Overview

The installation of the Bendix™ VORAD® VS-400 System is intended to cover a wide range of commercial vehicle applications. This
publication is intended to be a reference for commercial vehicle installations using the vehicle’s SAE J1939 data link interface. For vehicles
without a SAE J1939 data link, some installation procedures may vary for a proper system installation and operation.

Mounting Requirements - Forward Looking Radar (FLR)

The Forward Looking Radar (FLR) determines the distance, lane position (azimuth), relative speed (velocity), and direction of vehicles
in front of the host vehicle. The FLR is a Doppler radar that transmits at a 77 GHz frequency. A built-in yaw rate sensor (gyro) provides
relative azimuth for lane positioning in turns. The SAE J1939 interface allows the FLR to be installed as a Bendix™ SmartCruise™ adaptive
cruise control only stand-alone unit, or as a component of the complete Bendix™ VORAD® VS-400 System.

The FLR can track multiple objects simultaneously in relative motion within the radar’s effective range of view. Relative motion is defi ned
as an object’s movement towards, or away from, the radar transceiver.

Note: The Forward Looking Radar is only activated while the vehicle is in motion.

Note: The design of the Mounting Bracket may vary. This is a typical representation.

Located on the forward most position of the vehicle, the FLR transmits and receives low power, high frequency electromagnetic energy.
Transmitted energy that is refl ected off objects in front of the vehicle is received and processed by the radar’s internal microprocessor to
determine the object(s) relative distance, position (azimuth), speed (velocity), and direction of travel.

Mounting

Bracket

For proper operation, the 77GHz forward looking radar unit shall be installed on the vehicle with the following constraints:

• The radar unit must be rigidly attached to the forward most position of the vehicle chassis, perpendicular with the vehicle’s
forward thrust axis.

• The lateral position of the radar should be located as close to the vehicle’s center as possible (+/- 50mm).

• The vertical position of the radar must be at a minimum of 12” (304.8mm) and a maximum of 28” (711.2mm) from the ground.

• The radar must be installed in a manner that protects it from minor frontal impacts, as well as protecting the radar’s harness
connector from road debris.

• The mounting hardware must allow for a minimum of ±3° mechanical adjustment of the radar’s horizontal and vertical axis.

• The radar must be orientated so the harness connector is pointing in the downward position.

The mounting location must provide a clear view in front of the radar. Ideally, the radar will be recessed behind the profi le of the vehicle’s
front bumper or grill, but not to interfere with the radar’s sight profi le. See “No Radar Obstruction Zone” on next page.

Mounting Requirements

Requirements

The Forward Looking Radar can be mounted on the front of the vehicle, or integrated behind a non-metallic body panel as long as the
mounting, alignment, and material requirements are met in the following sections.

Field of View Defi nition

The Forward Looking Radar (FLR) fi eld of view in elevation and azimuth is illustrated below. The grey area represents a cross-cut view of
the three-dimensional “No Radar Obstruction Zone”.

Using the illustration below, the diameter of the hole in front of the Forward Looking Radar can de determined. For materials within 30mm
of the FLR, the hole diameter must be greater than 70mm. For materials 40mm from the front of the FLR, the hole diameter must be
greater than 90mm.

WARNING

!

▲

Any hole diameter less than the required size, will effect a clear line of sight for the FLR unit.

Mounting Requirements

Cover Material Requirements

Any material that may be located in the Forward Looking Radar’s fi eld of view (including bumpers, spoilers, etc.) can not be made out
of any metallic material or have any carbon content. It is recommended that any material that will be located in the FLR fi eld of view be
approved by Bendix Commercial Vehicle Systems prior to use.

If the radar has a cover perpendicular to the radar beam, even a very slight vibration of the cover can cause the refl ected radar signal to be
seen as a very strong false target at close range. If the radar cover is not perpendicular by more than 5° then the returned refl ection does
not enter the receiver channel and hence is not detected. The recommended angle of the beam to the cover is 50° to 80°. There have
been applications that have the cover perpendicular, but the forward radar and the cover were directly mounted to each other to minimize
the cover’s movement to the radar module. This may be a diffi cult condition to maintain.

The cover must not contain any metal or high carbon concentrations, as this reduces the radar range. The electrical characteristics of
the cover material (on microwave RF) and its thickness can effect the range as well. Polymeric or ceramic material is recommended.
Recommended thickness are based on the cover’s angle. The table on the following page lists material thicknesses for a perpendicular or
80° angle cover. The ideal thickness also depends on the angle of incidence of the cover relative to the radar beam axis. The materials in
this table do not represent the only possible make up for a cover.

The recommendation scoring system has been applied as follows:

• Losses shall be less than 0.7dB.

• Thickness for rigidity reasons shall be greater than 2mm.

Thickness accuracy: +/- 0.15mm

Thickness recommendation is based on cover being a fl at unpainted surface that extends beyond the “No Radar Obstruction Zone” (see
previous page). Since paints can impact the losses, they need to be evaluated separately. As with the cover, the paint must not contain
metal or carbon.

• The thickness depends on the angle of incidence of the bumper shield located in the radar fi eld view relative to the radar beam
axis; it should be updated with the real angle.

• The angle of incidence is recommended to be between 50° to 80°; 90° is prohibited so as to avoid any spurious refl ection of the
radar beam back into the Forward Looking Radar.

• Painting can induce extra losses that depend heavily on the painting thickness itself and on its painting process. These paints
need to be tested individually to assess their impact on the recommendations made in this document. For more information, see
the “Painting” section of this publication.
