DESCRIPTION

The Bendix® Wingman® Advanced™ system is an integrated combination of three features:

• Adaptive cruise control with braking;

• Alerts (several different types); and

• Collision mitigation technology.

PART ONE: ADAPTIVE CRUISE CONTROL WITH BRAKING

The adaptive cruise control with braking feature is an additional upgrade of ordinary cruise control. When using cruise control, the Wingman Advanced system will maintain the set speed, and also will intervene, as needed, to help maintain a set following distance behind a detected forward vehicle.

Using a radar sensor mounted to the front of the vehicle — with a range of approximately 500 feet — the Wingman Advanced system reacts to detected forward vehicles in the same lane, traveling in the same direction. See Figure 1.

The adaptive cruise control with braking feature is designed

FOR THE BENDIX® WINGMAN®

to help the driver maintain a set following distance between his vehicle and a detected forward vehicle when cruise control is set. See the gray "Radar Beam" area in Figure 2.

Once cruise control is set and the system is maintaining a set following distance between you and the vehicle in front:

RADAR

The STRIPED area approximates the zone where the collision mitigation feature is ready to intervene with up to two-thirds of the vehicle’s braking capacity, if needed, as long as the vehicle is traveling above 15 mph.

The GRAY area approximates the zone where the Wingman Advanced system – when cruise control is set – is ready to intervene with up to one-third of the vehicle’s braking capacity, if needed.

Detected Forward Vehicle

BEAM

NOT TO SCALE

If the vehicle in front of you slows down below the cruise control’s set speed, the Bendix® Wingman® Advanced

™

system will intervene and, as necessary, in this order:

(a) reduce the engine throttle; then

(b) apply the engine retarder; then

in an attempt to maintain the set following distance behind the vehicle ahead. NOTE: If during the intervention, it is necessary to apply the foundation brakes, the vehicle will not automatically resume the cruise control set speed.

If the vehicle ahead slows below the cruise control’s set speed, but then accelerates away, and the Wingman Advanced system did not need to use the foundation brakes, the system will automatically accelerate back to the original cruise control set speed, and again maintain a set following distance behind any detected forward vehicles.

Because the Wingman Advanced system operates along with normal cruise control, all the typical features built into cruise control work as usual. For example, limits

imposed by factory-set road speed governors, etc. are fully supported by the Wingman Advanced system.

PART TWO: ALERTS

Bendix Wingman Advanced also assists by giving audible and visual alerts, whether or not cruise control is on. See Pages 8-10 for more information on the three types of alerts the driver may hear and/or see displayed.

PART THREE: COLLISION MITIGATION TECHNOLOGY

See the striped area in Figure 2. The Wingman Advanced collision mitigation technology is designed to be ready to react to the presence of moving vehicles in front of your vehicle (whether or not cruise control is set). Collision mitigation interventions can be up to two-thirds of the vehicle’s braking capacity. The system provides the driver with an alert before an intervention occurs. The driver must immediately act to potentially avoid, or lessen the severity of, a collision.

WHEN NOT TO USE BENDIX WINGMAN ADVANCED ADAPTIVE CRUISE CONTROL WITH BRAKING

The adaptive cruise control with braking feature in Wingman Advanced is automatically ready when normal cruise control is set.

WARNING: This vehicle’s cruise control must be used only in the same conditions that are normally recommended for ordinary cruise control. As noted below, there are certain situations when cruise control should NOT be used.

• Inclement Weather/Low Visibility Situations – Do not use cruise control

in inclement weather or low visibility conditions such as rain, snow, smoke, fog, ice or other severe weather conditions that may affect the performance of the Wingman Advanced system.

• Dense Trafc – Do not use cruise control

in heavy trafc.

• Sharp Curves and Winding Roads – Do not use cruise control when traveling sharply curved or winding roadways. CAUTION: Road curvature may impact the radar’s ability to track vehicles ahead in the same lane.

• Entrance or Exit Ramps – Do not use cruise control when entering or exiting roadways.

• Downhill Grades – Do not use cruise control on downhill grades.

1.1 IMPORTANT SAFETY INFORMATION

This vehicle's cruise control must be used only in the same conditions that are normally recommended for ordinary cruise control. Vehicle manufacturers may use alerts, messages, and dash arrangements that vary from the examples shown here. Consult the vehicle operator’s manual for applicable details regarding use and operation.

• Construction Zones – Do not use cruise control in construction zones.

• Off-Road – Do not use cruise control in off-road conditions.

• Smaller Forward Vehicles – Smaller vehicles, such as motorcycles, may be

difcult for the radar to identify. It is the

driver’s responsibility to be aware of these types of vehicles and to slow down if necessary.

Visit www.bendix.com for more information along with any updates to these limitations and restrictions.

AUTOMATIC FOUNDATION BRAKE APPLICATIONS

The vehicle automatically manages foundation brake priorities among the various vehicle systems that use the foundation brakes, such as Bendix® Wingman® Advanced™ system, Bendix® ESP® Electronic Stability Program, Bendix® ATC (Automatic Traction Control) and Bendix ABS (Antilock Braking System).

NOTE: Cruise control will automatically cancel whenever the Wingman Advanced system applies the foundation brakes. You can verify that your cruise control is disengaged by observing that the cruise-enabled icon is no longer illuminated. You must resume or set cruise control in order to regain normal cruise control functionality and to reengage the adaptive cruise control with braking feature of the Wingman Advanced system.

Additional information, and complete troubleshooting procedures for the Bendix ESP stability system, can be found in the Bendix Service Data Sheet SD-13-4869.

1.2 SYSTEM COMPONENTS

The radar sensor (or radar) used in the Wingman Advanced unit is located at the front of the vehicle – either on the bumper or just behind it on a cross-member. See Figure 3.

Also see the Alerts and Warnings section of this manual for more detailed information about the alerts.

NOTE: For some integrated systems, the volume level of the alerts is not adjustable, nor can they be switched off.

1.3 ACTIVATING THE BENDIX® WINGMAN® ADVANCED™ SYSTEM

To have the Wingman Advanced cruise control with braking features of the Wingman Advanced system (engine dethrottle/retard, foundation brake interventions) the vehicle’s regular cruise control must be switched on. See Figure 5

for examples of switches that may be used.

When the vehicle reaches the desired cruise speed, the driver presses the cruise control set switch to activate the system. The Wingman Advanced system will then engage and help the driver maintain a set following distance behind the vehicle traveling in front.

Once the cruise control speed is set, a cruise-enabled icon (or similar) will illuminate on the instrument panel. If the cruise-enabled or set (or similar) icon does not illuminate, the Wingman Advanced system is not functioning normally. Refer to the vehicle operator’s manual to double-check the location of the icon, and for further troubleshooting information.

FIGURE 3 - COMPONENT: RADAR SENSOR

The radar sensor is pre-aligned at the factory and no adjustment should be needed. If the radar sensor becomes misaligned (or a diagnostic trouble code is issued), either a message – or light on the dash, depending on the vehicle – lets the driver know that service is needed.

The Wingman Advanced system is either fully integrated into the vehicle dashboard, or uses the Bendix® Driver Interface Unit (DIU). See Figure 4.

FIGURE 4 - BENDIX DRIVER INTERFACE UNIT (DIU)

Although the system functions the same, how the alerts are displayed to the driver can be different. Where a DIU (Driver Interface Unit) is used, all visual, text, and audible indicators and alerts will be provided by the DIU. The DIU allows the volume to be adjusted. See Appendix F.

The driver can switch off the Wingman Advanced system manually by either stepping on the brake pedal or switching off the cruise control.

FIGURE 5 - EXAMPLES OF CRUISE CONTROL SWITCHES

IMPORTANT NOTE: Cruise control will automatically cancel whenever Wingman Advanced applies the foundation brakes.

1.5 HOW A DRIVER INTERACTS WITH THE BENDIX® WINGMAN® ADVANCED™ SYSTEM

Table 2 illustrates how the Wingman® Advanced™ system will respond to various actions a driver may take when using Wingman Advanced system on the road.

The driver is always responsible for the control and safe operation of the vehicle at all times. The Bendix® Wingman® Advanced™ system does not replace the need for a skilled, alert professional driver, reacting appropriately and in a timely manner, and using safe driving practices.

How a Driver Interacts with Bendix® Wingman® Advanced™ (1.5)

Action Reaction of Wingman Advanced

If the driver does this: Expect the Wingman Advanced system to do this:

Steps on the brake. (During a collision mitigation event.)

The driver is always in control and is able to apply full braking power.

Steps aggressively on the accelerator. (During a collision mitigation event.)

Steps on the brake. (When in cruise.)

Steps on the accelerator. (When in cruise.)

Switches on the cruise control.

Switches off the cruise control.

Sets the cruise control speed.

Covers or blocks the radar.

Uses normal cruise control “+/-” switch.

TABLE 2 - HOW A DRIVER INTERACTS WITH BENDIX® WINGMAN® ADVANCED™

The driver is always in control. His/her actions override any Wingman Advanced system actions. Note: If cruise control is engaged, it will be overridden until the accelerator is released; then cruise control will resume the original set speed automatically.

Cruise control will be cancelled.

Cruise control will be overridden until the accelerator is released; then cruise control will resume the original set speed automatically.

Nothing. The adaptive cruise control with braking feature will not engage until the driver sets the cruise control speed.

The adaptive cruise control with braking feature will turn off; the collision mitigation feature remains active and ready to intervene. The driver will continue to hear all alerts as needed.

The adaptive cruise control with braking feature is automatically activated. Your vehicle maintains a set speed and following distance behind the vehicle ahead.

The Wingman Advanced system performance will be diminished or even disabled and a Diagnostic Trouble Code (DTC) will be set. A blockage will also affect engine cruise control availability.

Vehicle speed increased (+) or reduced (-) to achieve the new set speed while actively maintaining following distance with the vehicle ahead, if one is present within 500 feet.

NOTE: The system responses above are typical, but may vary from the descriptions shown here by vehicle manufacturer, or earlier versions of the Wingman Advanced system. These are examples of driver actions and typical Wingman Advanced system responses, however this chart does not attempt to cover all possible situations.

THE FORWARD VEHICLE DETECTED ICON

When cruise control is switched on and set and a vehicle ahead of you is detected by the radar, the detected forward vehicle icon — or similar — will illuminate on the vehicle dashboard.

This is an indication to the driver that the Bendix® Wingman® Advanced™ system is actively managing the distance between your vehicle and the vehicle ahead, and may intervene automatically, if needed.

See Figure 6 for examples.

FIGURE 6 - FORWARD VEHICLE DETECTED ICONS

ADJUSTING THE CRUISE CONTROL SPEED

Use the switch(es) provided by the vehicle manufacturer to set your cruise control speed. When adjusted, your set speed will typically be indicated on the vehicle dash, message center, or speedometer.

1.7 WINGMAN ADVANCED COLLISION MITIGATION FEATURE OPERATION

Whenever your vehicle is traveling at above 15 mph, the Wingman Advanced collision mitigation feature is ready to intervene, if needed. It does not require cruise control to be set. The collision mitigation feature of Wingman Advanced will alert you automatically and apply up to two-thirds of the vehicle’s braking capacity, if a collision with the detected forward vehicle is likely to occur. You, the driver, must immediately act to potentially avoid, or lessen the severity of, a collision.

Collision mitigation is ready to intervene as long as no DTCs are active in either the brake system, Wingman Advanced system, or any other contributing vehicle system.

AUTOMATIC FOUNDATION BRAKE APPLICATIONS

The vehicle automatically manages foundation braking priorities among the various vehicle systems that use the foundation brakes, such as Wingman Advanced, Bendix® ESP® (Electronic Stability Program), Bendix®ATC (Automatic Traction Control) and the Bendix® ABS (Antilock Braking System).

1.8 ALERTS AND WARNINGS

The Bendix Wingman Advanced system operates differently compared to other cruise control/forward collision warning systems. It is important for YOU to fully understand the system’s features, especially the driver alerts and warnings.

1.6 FOLLOWING DISTANCE

Following distance refers to the time gap, measured in seconds, between your vehicle and the vehicle ahead. The actual physical distance between the two will vary based on the speeds of both vehicles; however, the set gap will remain the same for all set cruise speeds.

FOLLOWING DISTANCE ADJUSTMENT SWITCH

This optional Wingman® Advanced™ feature, allows the driver to adjust the following distance or time gap. The availability of this feature is determined by the vehicle manufacturer. The switch has an increase or decrease function. Pressing increase (+) will provide a larger following distance, measured in seconds. Pressing decrease (-) will provide a shorter following distance.

Three important warnings provided by the Wingman Advanced system are the Following Distance Alert (FDA), Impact Alert (IA), and Stationary Object Alert (SOA). The driver will be alerted by any of the three warnings, whether or not the cruise control is activated.

See Appendix F, Sections 3.0-5.0, for more information about how DIUs communicate alerts.

WARNING: Any audible and/or visual alert by the

system means that your vehicle is too close to the vehicle ahead and the driver must immediately act to potentially avoid, or lessen the severity of, a collision.

IMPACT ALERT (IA)

FOLLOWING DISTANCE ALERT (FDA)

The Impact Alert is the most severe warning issued by the Bendix® Wingman® Advanced™ system. This alert indicates that a collision with the detected forward vehicle is likely and the driver must immediately act to potentially avoid, or lessen the severity of, a collision.

The Impact Alert is ready to alert the driver whenever the vehicle is moving above 15 mph.

When activated, the IA will sound and a visual message/ icon typically appears on the dash screen or Bendix® Driver Interface Unit (DIU) display. The actual sound/display method varies by vehicle manufacturer.

NOTE: The Impact Alert is typically accompanied by automatic brake interventions. The Wingman Advanced system will apply up to two-thirds of your vehicle’s braking capacity. The driver must apply additional braking, when necessary, to maintain a safe distance from the vehicle ahead.

See Figure 7 for an example of an Impact Alert Icon.

The Following Distance Alert (FDA) provides both audible and visual alerts whenever the time between your vehicle and the detected forward vehicle ahead is less than one and a half (1.5) seconds* and decreasing. Once the audible alert is given, the driver should increase the distance between his/her vehicle and the vehicle ahead until the audible alert stops.

The FDA is ready to alert the driver whenever the vehicle is moving above

ve (5) mph. If the following

distance continues to decrease, the driver will hear more rapid audible alerts. When the FDA reaches its highest level, typically a red LED also illuminates on the instrument cluster. The FDA may be accompanied by a visual alert.

* 1.5 seconds is the system default and may vary by

eet/OEM.

FIGURE 9 - DRIVER INTERFACE UNIT (DIU) SHOWING EXAMPLES OF FOLLOWING DISTANCE ALERTS WITH PROGRESSIVELY FASTER AUDIBLE ALERTS.

FIGURE 7 - EXAMPLE OF IMPACT ALERT ICON

FIGURE 8 - IMPACT ALERT TEXT AND LIGHT PATTERN AS

SEEN ON THE BENDIX® DIU

Above: Examples of other vehicle

manufacturer’s displays.

FIGURE 10 - FOLLOWING DISTANCE ALERT

STATIONARY OBJECT ALERT (SOA)

Stationary Object Alert (SOA) – The Bendix Wingman® Advanced™ system will give up to a three (3) second alert to the driver when approaching a detected,

sizable, metallic (radar-reective), stationary object in

your lane of travel. This alert indicates that a collision with a stationary object is likely and the driver must immediately act to potentially avoid, or lessen the severity of, a collision.

The SOA is ready to alert the driver whenever the vehicle is moving above ten (10) mph.

The driver should be especially careful when approaching certain types of vehicles or objects. The Wingman Advanced radar may not be able to detect vehicles and objects with limited metal surfaces (such as recreational vehicles, horse-drawn buggies, motorcycles, logging trailers, etc.).

NOTE: Entering a curve may reduce the alert time to less than three (3) seconds.

Advanced system foundation brake applications for at least 20 minutes.

• If the system does not detect a driver intervention within 15 seconds after the brake overuse alert sounds, it will shut itself off and set a Diagnostic Trouble Code (DTC). The driver will continue to receive alerts, but ALL Wingman Advanced interventions (de-throttling, engine retarder or brake applications) will be disabled until the next ignition cycle.

Note: In all cases, the driver still has the ability to apply the foundation brakes if necessary. The driver should take care since overheated brakes may reduce the vehicle’s braking capability.

(See Appendix F7.0).

FIGURE 11 - STATIONARY OBJECT ALERT DISPLAYED

BRAKE OVERUSE ALERT

The Bendix® Wingman® Advanced™ system provides a warning when the system is intervening and using the foundation brakes excessively. Overuse of the foundation brakes can lead to the brakes overheating and a potential loss of braking performance caused by brake fade. Using cruise control on downhill runs will

cause this alert to be activated.

Approach grades as you would normally, with the appropriate gear selected and at a safe speed. Cruise control should NOT be used on downhill grades.

When the system detects brake overuse, depending on the vehicle manufacturer, a text message will be displayed on the dashboard and an audible alert will be activated. The driver should intervene immediately.

FIGURE 12 - BRAKE OVERUSE WARNING

• Once the brake overuse alert is activated, certain

driver interventions that cancel cruise control – like

stepping on the brake pedal or switching off cruise – will

discontinue the alert. Following an overuse alert, the

driver should not reset cruise control for at least 20

minutes. This gives the brakes time to cool down. If

the driver chooses to reset cruise control during that

20 minute period, Wingman Advanced interventions

will be limited to de-throttling and engine retarder only.

The system will automatically disable all Wingman

1.9 WINGMAN ADVANCED SYSTEM DIAGNOSTIC TROUBLE CODES

The Wingman Advanced system is monitored and if any malfunction is detected, a Diagnostic Trouble Code (DTC) will be set and the driver will be alerted. The exact alert given depends on the vehicle manufacturer: refer to your vehicle operator’s manual and Sections 3 and 4.

1.10 RADAR SENSOR INTERCHANGEABILITY

Many variables must be considered when determining whether or not the radar sensor can be relocated from one vehicle to another vehicle. They include, but are not limited to, the version of the Bendix® ESP® stability system used on the vehicle, the instrument cluster, the vehicle ECU, the engine and the transmission. at 1-800-AIR-BRAKE to determine if this is a viable option.

WARNING:

without contacting Bendix rst!

Do not interchange radar sensors

Contact the Bendix Tech Team

1.11 ALERT VOLUME

For Wingman Advanced systems installed on vehicles with alerts that come directly through the instrument cluster, audible alert levels are pre-set at the factory and can not be turned off, nor can the volume be adjusted. However, where the Bendix® Driver Interface Unit (DIU) is used, volume adjustment is permitted.

1.12 POTENTIAL FALSE ALERTS

In certain unusual trafc or roadway conditions, Wingman

Advanced may issue a false alert.

Drivers should take into account the road conditions, and any other factors they are encountering, as they choose how to react to any alerts they receive from the Wingman Advanced system.

2.2 EQUIPMENT MAINTENANCE: BRAKE SYSTEM AND ABS FUNCTIONALITY

Importance of Antilock Braking System (ABS)

Maintenance – Optimal Bendix® Wingman® Advanced™ system braking requires a properly maintained ABS system, without any active ABS Diagnostic Trouble Codes (DTCs).

Have active DTCs repaired by a qualied technician. Any

ABS DTCs will cause Wingman Advanced to deactivate.

Importance of Brake Maintenance – Optimal

Wingman Advanced braking requires properly maintained foundation brakes (drum, wide-drum, or air disc) which meet appropriate safety standards and regulations. Brake performance also requires that the vehicle be equipped with

properly sized and inated tires, with a safe tread depth.

System Problems – If a problem with the Wingman

Advanced system is detected, depending on the vehicle manufacturer, typically there will be a message on the dashboard display. Depending on the type of problem detected, the system will determine if the vehicle may continue normal cruise control functions (without the

benets of Wingman Advanced), or whether all cruise

control functions should be disabled until service is performed. The system should be serviced as soon as possible to restore full Wingman Advanced functionality.

2.3 SYSTEM PREVENTIVE MAINTENANCE

The Wingman Advanced system is relatively maintenance free. The key items to keep the system functioning properly include:

1. Keep the radar lens clean and free of obstructions.

2. Inspect for any damage to the bumper or the Wingman

Advanced bracket or radar. Never use the radar unit

as a step. NOTE: If the radar sensor was originally installed behind a panel, check the panel for damage, etc. that may impact the radar’s performance before reinstalling. Replace the panel, if necessary, with an original OEM supplied panel. Do not paint over the

panel.

3. Perform appropriate inspections of the braking system as required by the manufacturer to ensure brakes are in proper working order.

4. Ensure that the tires are properly inated and that

adequate tread is present.

Radar Inspection – The driver should inspect the

radar and mounting bracket regularly and remove any mud, snow, ice build-up, or other obstructions. The installation of aftermarket deer guards, bumper guards, snow plows or similar potential obstructions is not recommended, and could impair the operation of the radar. See Appendix A3.

Radar Damage/Tampering - In cases where the

bumper and/or radar have sustained any damage, or if you suspect that the radar has been tampered with, do not use the cruise control until the vehicle has been repaired. In addition, an indicator on the dash typically will illuminate if the system detects any of these conditions. Consult your vehicle’s operator’s manual or contact Bendix for more information.

NOTE: Any vehicle trouble code that disables vehicle cruise control will also cause a diagnostic trouble code in Wingman Advanced.

3.1 TROUBLESHOOTING BASICS

This section introduces three initial steps to accurately troubleshoot the Bendix® Wingman® Advanced™ system.

We recommend reading this introductory section, as well as the Troubleshooting/Diagnostics Section (4.0), before performing any troubleshooting.

When diagnosing the Wingman Advanced system, a current version of Bendix® ACom® Diagnostics software will be required. This software is available as a free download from www.bendix.com.

Which radar sensor is installed?

The Wingman Advanced (FLR20) system covered in this SD sheet has a

at rectangular radar

sensor.

If your Wingman Advanced system has a black “eyeball” (FLR10) radar sensor, use SD sheet SD-61-4962 instead (formerly SD-13-4962.)

Troubleshooting Basics (3.1)

Questions Next Steps

Have the driver run the Power-Up Self-Test.

Power-Up Self-Test

This is a self diagnostic check, to determine if the system operation is normal.

Park the vehicle. Power off.

Put the key into the ignition, and turn to the “ignition power” position.

Toggle the cruise control switch at least once, and leave it in the “on” position.

Start the vehicle, but do not drive away.

Note that if the cruise control is in the “off” position, or if the vehicle is moving, this test will not run.

The self-test will start after 15 seconds, and takes approximately ve (5)

seconds to complete. (Note that other vehicle system self-tests, e.g. the ABS “chuff” test, may run during the initial 15 seconds after ignition “on.”) As the Wingman Advanced self-test runs, the driver should hear a short set of beeps. The test checks the engine, transmission, and brake systems to make sure they are communicating. In addition, depending on the vehicle, the test

may briey display a distance alert message and/or cause the Forward Vehicle

Detected icon in the instrument cluster to illuminate; this is normal.

Does the driver hear a long warning beep?

Have the driver describe the system behavior that they believe shows it is not working properly.

TABLE 3 - TROUBLESHOOTING BASICS

If no problem is found and the test is passed, no additional beeps/lamps will be displayed nor will a trouble code be set.

If the system has found an issue that will prevent it from functioning properly, a long warning beep will sound to alert the driver, and a Diagnostic Trouble Code (DTC) will be logged in the system (typically with a status indicator/dash icon illuminated). For descriptions of all DTCs, see Section 4.3: Diagnostic Trouble Codes.

When diagnosing the system, especially in cases where there are no diagnostic

trouble codes logged, nd out which part of the system behavior appears to be

operating improperly. See Section 3.2: Narrowing Down the Problem.

3.2 NARROWING DOWN THE PROBLEM

Use the questions found in Table 3.2 below to help assess if the Bendix® Wingman® Advanced™ system is not performing correctly. Be sure to have a thorough understanding of the system’s normal behavior; this will reduce the troubleshooting time. The table provides a guide to basic troubleshooting questions and possible corrective actions. Items in Italics cross-reference to the service procedures in this manual to repair the condition described.

If Bendix Tech Team assistance is needed, prior to calling 1-800-AIR-BRAKE (1-800-247-2725, option 2), complete the Troubleshooting Checklist (See Appendix E), to help reduce the time needed to troubleshoot the system.

Narrowing Down the Problem (3.2)

Questions Next Steps

Blocked Radar Sensor Issues

Is mud, ice, or snow covering the radar sensor?

Is anything blocking the view of the radar sensor?

Potential False Warnings

Do false alerts seem to happen in construction zones or going under bridges?

Mounting Problems

Is the radar sensor mounting location (bumper or cross-member) damaged?

• Does the system seem to not "see" as far as it “used to”, or warn on many more overhead bridges/signs than previously?

Does the mounting bracket look damaged or tampered with?

Other Questions

Has the system worked properly in the past and is not working correctly now?

Clean the radar sensor front surface immediately. Remove anything blocking the radar sensor then power cycle and read any remaining trouble codes.

Read Section 4.3: Diagnostic Trouble Codes. Read Appendix A3: FLR20 Radar Sensor Mounting Clearance. If the vehicle's cruise control is set and the radar sensor is blocked by ice, snow, mud, tampering, etc. so that it cannot "see" a forward vehicle, Wingman Advanced may log a diagnostic trouble code (DTC).

After the blockage is removed, the DTC will clear automatically when the vehicle’s ignition is cycled.

Add a visual check of the radar sensor for blockage to the driver’s pre-trip inspection checklist.

Several road scenarios have a tendency to cause false warnings, including construction zones and bridges. Unless these false warnings are frequent, the system is likely reacting normally. The driver should not set the cruise control in construction zones. If driver complaints persist, continue asking questions to more

narrowly dene the driving condition presenting the problems. Review proper

operating conditions in the operator's manual.

Re-align the radar sensor vertically and laterally. Use the following procedures:

• Inspect the radar mounting. A solid mounting surface is necessary in order to hold the alignment. If the bumper or mounting cross-member is damaged,

replace it rst, then align the radar sensor.

• Appendix B1 - Go to Appendix B1 and use the owchart to nd out the procedure needed. Follow the actions directed in the procedure and align the radar.

• Appendix B4 - Check the vertical alignment and adjust if needed.

Other than expected surface scratches or some discoloration over time, there should be no visible damage to the radar sensor bracket assembly. If so, realign the radar sensor vertically and laterally. If radar sensor alignment can not be held in place, the bracket assembly must be replaced. Verify the bumper is not damaged.

• Check the Vertical Alignment (6.6) and adjust if needed.

• Check the Lateral Alignment (6.8) and adjust if needed.

The Radar Sensor Mounting - The radar sensor needs a solid mounting surface in order to hold the alignment. If the bumper or mounting cross-member is

damaged, replace it rst, then align the radar sensor.

This is a good indication that something has changed; review the questions listed above with the driver to further diagnose the problem.

Has the radar sensor been changed recently?

TABLE 4 - NARROWING DOWN THE PROBLEM (PAGES 14-15)

If so, the new radar sensor may be incompatible with the vehicle. In addition, check any system trouble codes with Bendix® ACom® Diagnostics software.

Read Section 4.3: Diagnostic Trouble Codes.

Narrowing Down the Problem (3.2)

Questions Next Steps

Did the radar sensor currently on the vehicle come from another vehicle?

With cruise control set, does the system consistently apply the foundation brakes when a forward vehicle slows?

Does a diagnostic trouble code (DTC) seem to occur when driving through the desert or in barren areas (no road signs, trees or vehicles)?

Does the system seem to disengage after an automatic braking event?

Does cruise control disengage sometimes when the brakes come on and not at other times?

Does the connector or wiring appear damaged?

Does the system generate a diagnostic trouble code going down a grade when using ACB to slow the vehicle, but the code goes away later?

The radar sensor may be incompatible with the new vehicle. Follow Section

1.10: Radar Sensor Interchangeability procedure and check system trouble codes with Bendix® ACom® Diagnostics software. Read Section 4.3: Diagnostic Trouble Codes.

This is normal operation. Continue asking the driver questions to determine if the radar system interventions are not the expected Bendix Wingman Advanced behavior. If the radar system interventions are not typical, the radar sensor may be misaligned.

• Inspect the radar mounting. A solid mounting surface is necessary in order

to hold the alignment. If the bumper or mounting cross-member is damaged,

replace it rst, then align the radar sensor.

• Appendix B1 - Go to Appendix B1 and use the owchart to nd out the

procedure needed. Follow the actions directed in the procedure and align the radar.

• Appendix B4 - Check the vertical alignment and adjust if needed.

The service technician will need to check trouble codes as well. Read Section

4.3: Diagnostic Trouble Codes.

In normal operation, the adaptive cruise control with braking feature of Bendix® Wingman® Advanced™ system may indicate a DTC if it hasn’t detected a metallic object after a pre-determined period. This is rare, but most likely to occur when driving in deserts or barren areas. If the system does set a DTC, Wingman Advanced provides a visible warning to the driver. In addition, the vehicle also will drop out of cruise mode, providing an audible and/or visual warning to the driver as well. The driver must pull off the road, and cycle the ignition to before the vehicle’s cruise control can be used.

This is normal operation. The driver must set or "resume" the cruise control once again to regain the following distance function.

This is normal operation. When traveling with lightly loaded trailers, or “bobtail”, the adaptive cruise control with braking feature of Wingman Advanced may continue to function even after an automatic brake application. No driver input is needed.

Wires can become corroded if the radar sensor is not plugged in properly. Clean the connectors on the wire harness, as well as the radar sensor, and reattach. If wires are chafed, replace the wire harness. Also, check for trouble codes.

Read Section 4.3: Diagnostic Trouble Codes, and Section 4.8: Troubleshooting Wiring Harnesses.

This is normal operation. The adaptive cruise control with braking feature of Wingman Advanced is not intended to be used on grades. Verify there are no diagnostic trouble codes. Proper downgrade driving techniques should be used.

Read Section 4.3: Diagnostic Trouble Codes.

Does the radar sensor have noticeable damage beyond normal discoloration or surface scratches?

TABLE 4 - NARROWING DOWN THE PROBLEM (PAGES 14-15)

The radar sensor and bracket are very durable. However, if the radar sensor housing or cover is cracked or broken, immediately look for trouble codes via a current version of Bendix® ACom® Diagnostics and replace the damaged radar sensor. Read Section 4.3: Diagnostic Trouble Codes, and Appendix A.02: Radar Sensor Mounting.

3.3 OVERVIEW OF POSSIBLE ISSUES

Some customer issues are actually misunderstandings of how the Bendix® Wingman® Advanced™ system performs normally. Use Table 5 below to learn the causes of potential issues if Wingman Advanced is not performing correctly. Some issues can be investigated by a visual inspection. Others may cause a diagnostic trouble code (DTC) to be logged: See Section 4.3: Diagnostic Trouble Codes.

Overview of Possible Issues (3.3)

Issue Description

Vehicle diagnostic trouble codes (DTCs)

System familiarity Verify the system functionality. Is it operating normally or not? Drivers who are unfamiliar

DTCs caused by temporary operating conditions

Radar sensor blocked

Damaged radar sensor or bracket

Damaged connector or wiring

Radar sensor misalignment

The Wingman Advanced system will not operate and will set a DTC if any of the following vehicle systems also show a DTC: engine, engine cruise, instrument cluster, Bendix® ABS, Bendix® ATC, Bendix® ESP, or transmission. These components must be repaired and cleared of DTCs before troubleshooting Wingman Advanced. (NOTE: Clearing the vehicle

DTCs may be the only step needed to reestablish full Wingman Advanced functionality. See Section 4.4: Clearing Diagnostic Trouble Codes (DTCs)

with the system may report dissatisfaction over the way it beeps or how it activates the brakes. Use Section 3.0: Introduction to Troubleshooting, Section 4.3: Diagnostic Trouble Codes and Section 3.1: Troubleshooting Basics to verify if the system is functioning normally; then continue.

Some Diagnostic Trouble Codes (DTCs) indicate a temporary condition and will clear when that condition is no longer present. If these persist, further investigation is warranted. See Section 3.1: Troubleshooting Basics.

If the system doesn’t seem to work at all, the radar sensor may possibly be blocked. A DTC will also be set. Visually inspect it, clear the blockage, turn the ignition on and run through a power cycle. See Appendix A3 for more information about radar mounting clearance.

If the vehicle has been in an accident, it is likely the radar sensor will need to be re-aligned or replaced. Inspect the radar sensor and housing for damage. Radar sensor discoloration

or small scratches may be acceptable. Signicant damage (such as cracks, or broken

pieces) will require radar sensor replacement. Regardless of the exterior condition, check for diagnostic trouble codes outlined in the Section 4.3: Diagnostic Trouble Codes (DTCs) to determine if radar sensor replacement is necessary.

Visually inspect the connector and wire harness for corrosion or chang. Refer to Sections

4.5: Troubleshooting Diagnostic Trouble Codes: Power Supply and 4.6 Serial Data (J1939) Communications Link of this document for additional troubleshooting.

Inspect the front of the vehicle. If (a) it has been damaged, or (b) if the vehicle does not track straight, either of these conditions must be repaired before troubleshooting Wingman Advanced.

If there is a DTC set or if the system does not function, the radar sensor may be severely misaligned and Wingman Advanced will not operate until this is corrected. See Appendix B - Bendix Wingman Advanced Radar Alignment.

J1939 network problems

Power to radar sensor problems

TABLE 5 - REVIEW OF POSSIBLE ISSUES

If the entire system is non-functional, it may be a J1939 network problem. Follow the instructions in Section 4.6: Serial Data (J1939) Communications Link.

If the entire system is non-functional, another likely cause may be a lack of power to the radar sensor. Follow the instructions in Section 4.5: Troubleshooting Diagnostic Trouble Codes: Power

Supply.

4.1 BENDIX® ACOM® DIAGNOSTICS SOFTWARE

Bendix® ACom® Diagnostics is a PC-based software program available as a free download from the Bendix web site (www.bendix.com) or on a CD from the online Bendix Literature Center (order BW2329). This software provides the technician with access to all the available ECU

diagnostic information and conguration capability. For

Bendix® Wingman® Advanced™ diagnostics, use a current version of ACom Diagnostics.

FIGURE 13 - BENDIX® ACOM® DIAGNOSTICS SOFTWARE

STARTING ACOM® DIAGNOSTICS

The Bendix ACom Diagnostics software can be started from the desktop shortcut, or from the main Windows® screen with “Start-Programs-Bendix-ACom® Diagnostics.” See Figure 14 and also Appendix G. To begin, the technician selects “Wingman” from the Starter screen, then “Start with ECU” from the Diagnostic Control panel.

FIGURE 14 - STARTING BENDIX® ACOM® DIAGNOSTICS SOFTWARE

NOTE: When using ACom Diagnostics for the rst time, the

service technician will be asked to select the communication adapter for both the Wingman Advanced and Bendix® EC-60™ controllers. While both controllers will use the same physical adapter, the technician will need to indicate which communication protocol to use for each. Once a successful connection has been made, these steps will no longer be necessary.

The Bendix® ACom® Diagnostics for ABS User Guide is available for download at www.bendix.com and should be used as a reference to all functions of the ACom service tool.

In general, the protocol for Wingman Advanced is described as CAN or CAN 250. (See Figure 15 for an example of an adapter compatible with Wingman Advanced). The Bendix

EC-60™ controller protocol will be described as J1708,

J1587, or Unied Diagnostic Services (UDS).

4.2 READING DIAGNOSTIC TROUBLE CODES (DTCs)

If the system generates a Diagnostic Trouble Code (DTC), where a lamp or icon is illuminated on the instrument cluster or the driver display, then a current version of ACom Diagnostics software is required. Select “Wingman” from the starter screen, then “Start with ECU”. Click “DTC” to show the diagnostic trouble codes. See Appendix G

for screen shots. See Section 4.3 for a complete table showing DTCs and troubleshooting information.

Verify the engine ECU conguration. Check for other

devices inhibiting J1939 communications.

4.7 ENGINE COMMUNICATIONS (J1939) TEST PROCEDURE

The Bendix® Wingman® Advanced™ system requires several J1939 messages from the engine ECU to control the engine and retarder torque for distance control and braking. The Wingman Advanced system will set a diagnostic trouble code if one of these messages is not present.

Use the engine manufacturer’s diagnostic test procedures to verify that there are no errors present in the engine that may prevent the Wingman Advanced system from controlling the engine or retarder torque.

4.7.1 J1939 TROUBLESHOOTING

PROCEDURE

1. Take all measurements at the harness connector unless

otherwise indicated.

CAUTION: DO NOT INSERT PROBES INTO THE BACK

SIDE OF THE CONNECTOR AS THIS WILL DAMAGE THE SEAL AROUND THE WIRE.

CAUTION: DO NOT INSERT ANY PROBE INTO THE

PIN ON THE MATING CONNECTOR OF THE RADAR SENSOR THAT IS GREATER THAN 0.62 MM DIAMETER OR SQUARE. THIS WILL DAMAGE THE CONNECTOR PIN

AND REQUIRE REPLACEMENT OF THE HARNESS.

2. Check for damaged or reversed J1939 wiring.

If the J1939 HIGH or J1939 LOW wiring circuits are

damaged, such as shorting together, the entire J1939 link will be lost. The problem may be intermittent, enabling the J1939 link to operate normally sometimes. In that event, multiple diagnostic trouble codes will be logged in multiple engine and vehicle controllers.

If the J1939 HIGH and J1939 LOW wiring circuits are

reversed, communication over the entire J1939 link will not be lost. Only those devices that are outside of the problem point from other devices will not receive, or be able to transmit, data messages.

3. Check for corroded or damaged wiring connector

problems such as opens or shorts to voltage or ground.

If the connector terminals are corroded, this may be

an indication of water intrusion into the wiring system and possibly into the radar sensor. Replacement of the entire harness is recommended. If the terminals of the radar sensor are corroded, replacement of the radar sensor is recommended.

4. Check for other J1939 devices which may be inhibiting

J1939 communication. The service technician should consult the vehicle manufacturer’s procedures for other J1939 troubleshooting procedures. The device’s power should be removed and measurements made at the ECU pins for shorts to ground and power pins and resistance between the J1939 HIGH or J1939 LOW input circuits.

5. Unplug the radar sensor. With the ignition switch off, measure the resistance (ohms) using a multimeter between harness pins 1 and 8. The reading should be approximately 60 ohms. If it is not, the vehicle wiring should be investigated using procedures described by the manufacturer.

6. Unplug the radar sensor. With the ignition switch off, using a multimeter, measure the resistance in ohms, between harness pin 1 and ground. The measurement should indicate an open circuit or very high resistance. If this is not the case, the vehicle wiring should be investigated using procedures described by the manufacturer.

7. Unplug the radar sensor. With the ignition switch off, using a multimeter, measure the resistance in ohms, between harness pin 8 and ground. The measurement should indicate an open circuit or very high resistance. If this is not the case, the vehicle wiring should be investigated using procedures described by the manufacturer.

4.8 TROUBLESHOOTING

WIRING HARNESSES

All wire harness connectors must be properly seated to maintain environmental seals. Push the mating connector until it seals with a click. Press the orange locking tab towards the center of the radar. When replacing an Advanced radar sensor, check that the wire harness connector is free of corrosion before plugging into a new radar sensor. Check for corroded or damaged wiring connector problems such as opens or shorts to voltage or ground.

If the connector terminals are corroded, this may be an indication of water intrusion into the wiring system and possibly into the radar sensor. Replacement of the entire harness is recommended. If the terminals of the radar sensor are corroded, replacement of radar sensor is recommended.

WARNING: Under no circumstances must the radar be removed or repositioned from the original production

line installation. The assembly should always be mounted in the original OEM location. If this location is not in the

center of the vehicle, the mounting offset will need to be programmed through Bendix® ACom® Diagnostics software.

CAUTION: Vehicle equipment, including bumpers, deer guards, etc. must not infringe upon the zone used by the radar sensor to emit and receive radar waves. See Appendix A3. Failure to comply with this requirement will impair the function of the radar. Only vehicle OEM-approved covers and/or cover panels may be installed in front of the radar.

The radar sensor assembly is mounted to the front of the vehicle using an adjustable bracket. This adjustable bracket allows for the radar sensor to be properly aimed laterally and vertically to maximize Wingman Advanced system

performance. When mounting a radar sensor, the wire harness connector should always point towards the passenger side of the vehicle.

A.1 VEHICLE APPLICATIONS

The radar sensor can be mounted and installed only on vehicles that have Bendix Wingman Advanced already installed.

At this time Wingman Advanced cannot be retrotted onto vehicles, even if that vehicle is equipped with the Bendix®

ESP® stability system.

CAUTION: Vehicle equipment, including bumpers, deer guards, etc. must not infringe upon the zone used by the radar sensor to emit and receive radar waves. Failure to comply with this requirement will impair the function of the radar. Only vehicle OEM-approved covers and/or cover panels may be installed directly in front of the radar.

For proper operation of your Wingman Advanced system, adhere to the following guidelines:

• The radar sensor assembly should be OEM-installed

on the vehicle following all OEM specications.

ZONE THAT MUST BE

KEPT CLEAR!

• The radar’s eld of view must NOT have interference

from any other vehicle components such as bumpers, cow-catcher bumpers, engine blankets, seasonal decorations, or any other commonly mounted front-of-

vehicle components. The radar signal is emitted from the front of the sensor with a spreading beam. In order to ensure that no adverse interference is experienced from bumpers or other nearby vehicle equipment, a suitable clearance must be maintained around the radar. This clearance must be maintained regardless if the vehicle is stationary or in motion. See the diagram below for a general guide and an example of how to calculate the zone required.

NOTE: Bendix does not certify nor offer warranty on Bendix Wingman systems where system performance is affected by beam obstructions of any kind or unapproved post-production covers. This document gives general guidelines that will work for most vehicles; exceptions may exist.

Keep all deer and moose guards,

bumpers, etc. outside of the required

radar beam clearance area.

B1.1 GENERAL INFORMATION ABOUT ADJUSTING THE ALIGNMENT

Accurate vertical and lateral alignment of the radar sensor is critical for proper operation of Bendix® Wingman® Advanced™. If the alignment is outside a certain range it could cause false warnings, missed warnings and a diagnostic trouble code in the system.

The radar sensor is mounted to the front of the vehicle using a bracket with three stand-offs, two of which are used when making adjustments, if necessary.

It is important to use the correct stand-off when making any alignment adjustments.

B2 LATERAL ALIGNMENT USING THE LEARNED ALIGNMENT SCREEN

This is the preferred and recommended method for lateral alignments

This method is for vehicles with Bendix® DIU® displays that use software whose version is 12.220 and above. To verify the DIU’s software version go to the Volume screen, where it is displayed in the top right-hand corner.

If the radar’s lateral alignment is not correct, the system calculates over the course of many hours of driving, an alignment adjustment value. The DIU displays the learned alignment value, and also shows the technician the direction to turn, and number of turns to make to, the lateral alignment adjustment screw.

B2.1 Tools needed: DIU (with software version 12.220 or above), and a Torx T-20 Screwdriver.

B2.2 Enter the DIU menu item titled “Radar” and select “Alignment Check”.

B2.3 Upon selecting the “Alignment Check” menu item the following screen will be displayed:

For example, the Figure above shows a correction value of ve (5) full turns counterclockwise is needed. The

correction count and arrow direction displayed shows that in order to adjust the radar to be correctly aligned with the travel of the vehicle, the lateral adjustment screw (lower right screw when facing the front of the vehicle) should be turned.

B2.4 Make the adjustment shown on the DIU.

IMPORTANT: Make necessary adjustments to the alignment standoff prior to resetting the alignment value.

B2.5 Select “Reset” and then “Exit” on the Bendix DIU screen to return to the default screen.

B2.6 Cycle the ignition power.

B2.7 IMPORTANT: Before returning the vehicle to service, go to Section B4 and check the vertical alignment.

Bendix FLR20 Radar Dynamic Alignment Method

This procedure may be used in rare cases where the stored alignment value is not

available. The vehicle must have a DIU with a software version 12.220 or above.

LATERAL ALIGNMENT USING THE DYNAMIC ALIGNMENT METHOD

Use the owchart B1 to be sure you are using the correct alignment procedure. This procedure is used in

the rare cases where a learned alignment value is not available. For example, in cases where a technician erroneously resets the alignment value before recording the Learned Alignment correction value and direction.

D1.1 Tools needed: DIU (with software version 12.220 or above), and a Torx T-20 Screwdriver. The assistance of

another vehicle will be necessary, and an assistant in the cab of the vehicle with the driver.

The DIU’s software version can be seen in the top right-hand corner of the Volume screen. The Bendix DIU’s

Dynamic Alignment Screen is used to show a dynamic calculation of the alignment of the radar.

D1.2 To perform the inspection, the vehicle must be traveling behind a cooperative vehicle on a straight, level length

of highway. Obeying all trafc laws, follow the vehicle in the same lane at a speed greater than 35 MPH.

For the most accurate results, the distance between the vehicles must be between 50 and 300 feet (15 to 91

meters), so the observed distance gure, displayed in the top left-hand corner of the display helps the driver

maintain the correct range. Verify that both vehicles remain in the middle of the lane during the test. The radar determines the distance and alignment to the vehicle ahead, and, if needed, calculates an alignment correction value, displayed on the screen.

D1.3 During the test, an assistant in the vehicle should observe where on the scale the triangle indicator shows the

alignment correction value. Because this is a dynamic measurement, the arrow will typically move through a range of positions. Note the average position where the triangle points over a length of time. This value gives the number of turns of the lateral adjust screw clockwise (CW) or counterclockwise (CCW), in order to correct any misalignment present. See Figure below. The number of turns may require less than a full screw turn, e.g. half way between 2 and 3 is 2.5 turns. The scale to the left of center shows when a clockwise (CW) adjustment is needed, and numbers to the right are for counterclockwise (CCW) adjustments.

The indicator triangle will move along the scale to show the number and direction of turns to make of the adjustment screw.

CW = Clockwise CCW = Counterclockwise

F1 Operator Interface

The Bendix® Wingman® Advanced™ system is either integrated into the vehicle's dash or console, or uses the Bendix® Driver Interface Unit (DIU) to communicate with the driver. (For integrated systems, see the vehicle

operator’s manual for more information.)

This Section describes the functions of the DIU. The DIU mounts in, or on, the vehicle dash and provides the interface between the driver and the Advanced system. The DIU provides visual and audio warnings to the driver and accepts input from the driver through the “Up”, “Down” and “OK” buttons.

The DIU contains an internal speaker to provide audible warnings, 2 LED arrays (one each in yellow and red), a single orange and blue LED and an LCD screen for visual warnings, and a light radar sensor to distinguish between day and night conditions.

F1.1 Start-Up Mode

At initialization, the DIU executes self-test routines during which the following screens are displayed and all

The modied volume setting will be retained through ignition cycles unless congured not to do so. If not congured, the volume setting will default to 100% on each new ignition cycle.

NOTE: The DIU can be congured to limit the minimum volume setting that the driver can select. The bar

shown above always represents the adjustable range based on minimum and maximum values. For example, if the minimum value is set to 50% (midpoint between lowest (70 +/- 3dB) and highest (89 +/- 3dB) audio levels, the bar represents an adjustable range from 50% (approx. 80dB) to 100% (approx. 89dB). Once the minimum (or maximum) has been reached, a message will be shown indicating that further adjustment is not allowed (e.g. “Minimum volume reached”). The step change per button press is approximately 2dB.

F1.4 Distance Setting (Dist. Setting)

On systems where changes are permitted, the “Distance Setting” option from the main menu will adjust the following distance that the Bendix® Wingman® Advanced™ system will attempt to maintain while in the following

distance mode. Distance Settings 1, 2, 3, and 4 will have different meanings based on the conguration chosen

by the user in Bendix® ACom® Diagnostics software. Generally, 4 relates to the farthest distance setting available

and 1 relates to the closest distance setting available. In many of the Advanced congurations available in ACom®,

two or more distance settings may be made equivalent to one another.

For more information on user congurations available through the Bendix ACom Diagnostics software, see

Section 5.4: Conguring Bendix Wingman Advanced Following Distance Alerts in this Service Data sheet for further information.

Selecting “Dist. Setting” from the main menu displays the following screen:

(No LEDs Illuminated)

F1.5 Distance Units (Dist. Units)

From the “Dist. Units” menu item, the user may choose to have the following distance from the forward vehicle displayed in either seconds or feet. By default, this item is set to seconds. If the user selects feet, the DIU will display the approximate distance from the bumper to the selected forward vehicle in feet. If the user selects seconds, the DIU will display the approximate distance from the bumper to the selected forward vehicle in seconds.

NOTE: Following distance in seconds is calculated based on the current speed of the Wingman® Advanced-equipped truck, and the distance, in feet, away from the selected forward vehicle. For instance, if the selected forward vehicle is 88 feet from the bumper of the Wingman Advanced-equipped truck, and the Wingman Advanced-equipped truck is traveling 60 mph, then the following distance in seconds would be 1.0 seconds because a truck traveling 60 mph can travel 88 feet in one (1) second.

The light sensor reading determines whether the current cab lighting mode is bright (day) or dark (night). When the light mode is bright, any brightness adjustment made by the driver is applied to only the bright mode setting. Likewise, when the light radar sensor sets the light mode to dark, any brightness adjustment made by the driver is applied to only the dark mode setting. This functionality allows the driver to adjust the brightness setting for the two cab lighting conditions after which the DIU will automatically toggle between the two settings based on the light radar sensor’s input. Both the bright mode setting and the dark mode setting are stored across power cycles.

NOTE: The DIU does not allow the brightness control to completely shut off the LEDs.

F1.8 System Status

This screen shows the congured features of the system and their current operational status (i.e., “Failed”

or “OK”). The failed status means that some system malfunction is preventing the feature from properly operating and that the feature is not available for use by the driver at this time. Pressing “OK” exits this menu item.

F2.0 Driver Demonstration Mode

Selecting Demo from the main menu starts a demonstration mode that shows the various lights, display

screens, and sounds produced by the DIU – along with a brief explanation of their meaning – for the congured

features. Pressing the down ( ) arrow button advances through the screens. The up ( ) arrow button has no functionality in this mode. The mode may be exited at any time by pressing the OK button.

NOTE: This mode can only be entered while the vehicle is not moving. Also, while in the demonstration mode, if the vehicle begins to move, the demonstration mode terminates.

If a screen is associated only with a congurable feature, and that feature is not congured, then that screen

will not be shown in the demonstration mode.

The screens presented to the driver in the demonstration mode are shown with the following text: “Error! Reference source not found.”

F3.0 Following Distance Alerts (FDAs)

One of the features of the Bendix® Wingman® Advanced™ system is the Following Distance Alert (FDA). A proprietary system combining vehicle speed, forward vehicle speed, distance, and driving scenario, FDAs are used to provide the driver with distance alerts which are intelligent, in that they will give appropriate distance alerts for the given situation. They alert the driver to objects far ahead in highway and country road driving

situations while not over-alerting in dense city trafc.

The radar sensor uses the DIU to communicate the FDA alerts to the driver. This system can be congured

through a current version of Bendix® ACom® Diagnostics software, for use by a eet as a driver training tool with or without coordinating the data made available by Wingman Advanced. In addition to being a reminder of when a driver may be dangerously close to the vehicle ahead, the following distance alerts may also be

congured to reinforce safe following distance habits taught by the eet.

The FDA is based on the following interval between the host vehicle and the object ahead. In other words, this is the time required by the host vehicle to travel forward and reach the object’s current location. With the

exception of the volume, the FDA may not be adjusted by the driver through the DIU. A qualied technician

must connect to the vehicle through the diagnostic port and run ACom® Diagnostics, in order to change the

conguration. The volume can not be turned all the way down, but other adjustments may be made by the eet. See Section B1.3 for more details on volume adjustment.

The FDA system is intended only to alert the driver about following distance. For more information on alerts for forward objects with high relative velocities and sudden decelerations, see Section B4.0: Impact Alert.

Only objects detected in the vehicle's lane, traveling in the same direction, are considered valid objects for the FDA. For more information on stationary objects, see Section B5.0: Stationary Object Alert.

See Section 5.4: Conguring Bendix Wingman Advanced Following Distance Alerts.

Appendix F

F3.1 Object Detected

When there is no valid object detected and no other high priority alert is displayed, the DIU will stand by with the following screen:

(No LEDs Illuminated)

When a valid object is detected, and is outside the range of the rst level of alert, and no other higher priority

alert is displayed, the DIU will display the following and no audio tones will be issued. The distance to the object will be displayed in large characters in the white space at the center of the screen (not shown) in seconds, feet, or meters, depending on the menu-selected preferences. By default, seconds will be displayed.

F3.2 Following Distance Alert (FDA) Level 1 (Slow audible two-tone alert/single LED illuminated)

When FDA Level 1 is issued, the following distance to the object/vehicle ahead has been reduced to the

distance determined in the current conguration for FDA Level 1. The DIU will begin to give the driver audio

and visual alerts for as long as the forward vehicle is in this zone and traveling at the same speed or slower.

The DIU will not display following distance units while in an FDA Level. For FDA Level 1, the audible alert will be a single repeating tone, and the visual alert is a single yellow LED and a screen with the vehicles slightly closer as shown below.

F3.3 Following Distance Alert (FDA) Level 2 (Medium audible two-tone alert/two LED’s illuminated)

The DIU will give the driver audio and visual alerts for as long as the object/vehicle ahead is in this zone and traveling at the same speed or slower. The DIU will not display following distance while in an FDA Level. For FDA Level 2, the audible alert will be a repeating double tone, and the visual alert is two yellow LEDs and a screen with the vehicles closer as shown below.

F4.0 Impact Alert (IA)

The “Impact Alert”, uses a combination of distance to the vehicle ahead, plus high relative velocity, to decide when to issue a loud solid tone, as well as a visual indicator to the driver. The red LED bar across the top of the DIU will

illuminate and “ACB Requires DRIVER INTERVENTION” will ash using the two screens below:

All Red LEDs Illuminated

When the Impact Alert activates, the driver must immediately act to potentially avoid, or lessen the severity of, a collision.

The impact alert can not be congured or turned off.

NOTE: At most, the adaptive cruise control with braking feature of Bendix® Wingman® Advanced™ will apply up to one-third of the vehicle’s braking capacity. The driver must apply additional braking, when necessary, in order to maintain a safe distance from the vehicle ahead.

F5.0 Stationary Object Alert (SOA)

Stationary Object Alert (SOA) is an alert given to the driver when the radar detects a sizeable, nonmoving metallic object in the vehicle's path of travel. To reduce the number of false detections, such as bridges and

overhead signs, an advanced set of lters are put in place so the SOA will not warn on every stationary object.

The SOA can be congured to be on or off through Bendix® ACom® Diagnostics.

If a SOA is issued, the DIU will very briey send out an alert identical to a very brief FDA Level 2: continuous

tone and two yellow LEDs, with the display image switching between the two shown below.

F7.0 Brake Overuse Alert

Using cruise control on downhill runs is the primary cause for this alert to be activated. Cruise control should

NOT be used on downhill grades. Approach grades as you would normally, with the appropriate gear selected and at a safe speed.

To guard against foundation brake overuse by the adaptive cruise control with braking feature of the Bendix® Wingman® Advanced™ system, the frequency of foundation brake interventions is monitored. If the system detects a situation where the brakes are being applied too frequently by the system in a given time period, the brake overuse alert will activate. This is designed to help prevent overheating of the brakes, which may lead to brake fade and reduced vehicle

braking capability. In this situation, the Brake Overuse Alert will ash a message requesting driver intervention. Also, an

audible alert will sound and a blue LED will blink on the Bendix Driver Interface Unit (DIU), as illustrated below:

This alert will continue for 15 seconds, during which time the driver should step on the brake or turn off cruise control using the cruise control on/off switch.

• The intervention cancels cruise control.

• After a Brake Overuse Alert, for a period of time (typically 20 minutes), the Wingman

Advanced system will not use the foundation brakes when intervening. The system will be limited to de-throttling the engine and applying the engine retarder during this time.

Note: In all cases, the driver still has the ability to apply the foundation brakes if necessary. The driver should take care since overheated brakes may reduce the vehicle’s braking capability.

• The time period for this mode is measured from the time the Brake Overuse Alert was activated and lasts approximately 20 minutes.

• Note: The driver will continue to receive all three alerts (FDA, Impact, and Stationary Object).

• Additionally, the DIU message will change to “ACB Braking Overuse” and the blue LED will remain lit, as shown below:
