2. Navigation system outline

(a) Vehicle position tracking methods

It is essential that the navigation system correctly tracks the current vehicle position and displays it on the map. There are 2 methods to track the current vehicle position: autonomous (dead reckoning) and GPS* (satellite) navigation. Both navigation methods are used in conjunction with each other. *GPS (Global Positioning System)

NAVIGATION – NAVIGATION SYSTEM

Operation Description

The radio and navigation assembly calculates the current vehicle position (direction and current position) using the direction deviation signal from the gyro sensor and the running distance signal from the vehicle speed sensor and creates the driving route.

The radio and navigation assembly displays the vehicle track on the map by processing the vehicle position data, vehicle running track, and map data from the map disc.

The map data from the map disc is compared to the vehicle position and running track data. Then, the vehicle position is matched with the nearest road.

The vehicle position is matched to the position measured by GPS. Then, the measurement position data from the GPS unit is compared with the vehicle position and running track data. If the position is widely different, the GPS measurement position is used.

The running distance signal from the vehicle speed sensor includes the error caused by tire wear and slippage between the tires and road surface. Distance correction is performed to account for this. The radio and navigation assembly automatically offsets the running distance signal to make up for the difference between it and the distance data of the map. The offset is automatically updated.

Navigation is performed even where the GPS radio wave does not reach.

NAVIGATION – NAVIGATION SYSTEM

HINT: The combination of autonomous and GPS navigation makes it possible to display the vehicle position even when the vehicle is in places where the GPS radio wave cannot receive a signal. When only autonomous navigation is used, however, the mapping accuracy may slightly decline.

(b) Autonomous navigation

This method determines the relative vehicle position based on the running track determined by the gyro and vehicle speed sensors located in the radio and navigation assembly. (1) Gyro sensor

Calculates the direction by detecting angular velocity. It is located in the radio and navigation assembly.

(2) Vehicle speed sensor

Used to calculate the vehicle running distance.

NAVIGATION – NAVIGATION SYSTEM

This method detects the absolute vehicle position using radio waves from a GPS satellite. * GPS satellites were launched by the U.S. Department of Defence for military purposes.

Current longitude/latitude/altitude is determined using the radio wave arrival time from four satellites.

NS–7

GPS

Number of satellites Measurement Description

2 or less Measurement impossible

3 2-dimensional measurement is possible

4 3-dimensional measurement is possible

Vehicle position cannot be obtained because the number of satellites is not enough.

Vehicle position is obtained based on the current longitude and latitude. (This is less precise than 3-dimensional measurement.)

Vehicle position is obtained based on the current longitude, latitude and altitude.

I100029E03

NS–8

NAVIGATION – NAVIGATION SYSTEM

(d) Map matching

The current driving route is calculated by autonomous navigation (according to the gyro sensor and vehicle speed sensor) and GPS navigation. This information is then compared with possible road shapes from the map data in the map disc and the vehicle position is set onto the most appropriate road.

Start

Map Matching

Actual driving route

Driving route on the display (Route by estimation)

The system compares the shape of the roads L1, L2 and L3 to the estimated running track after the vehicle makes a right turn. At point A, the vehicle position differs enough from the shape of L1 that the display switches to the road L2.

6. AVC-LAN Description

(a) What is AVC-LAN?

AVC-LAN, an abbreviation for "Audio Visual Communication Local Area Network", is a united standard developed by the manufacturers in affiliation with Toyota Motor Corporation. This standard pertains to audio and visual sign als as well as switch and communication signals.

Example:

Radio Receiver (Resistor 60 to 80 Ω)

AVC-LAN

I100032E09

NS–14

NAVIGATION – NAVIGATION SYSTEM

(b) Purpose:

Recently , car audio systems have rapidly developed and the functions have vastly changed. The conventional car audio system is being integrated with multi-media interfaces similar to those in navigation systems. At the same time, customers are demanding higher quality from their audio systems. This is merely an overview of the standardization background. The specific purposes are as follows: (1) To solve sound problems, etc. caused by using

components of different manufacturers through signal standardization.

(2) To allow each manufacturer to concentrate on

developing products they do best. From this, reasonably priced products can be produced. HINT:

• If a short to +B or short to ground is detected in the AVC-LAN circuit, communication is interrupted and the audio system will stop functioning.

• If the audio system has a navigation system installed, the multi-display unit acts as the master unit. If the navigation system is not installed, the audio head unit acts as the master unit instead. If the radio and navigation assembly is installed, it is the master unit.

• The radio and navigation assembly contains a resistor that is necessary to enable communication on the different AVC-LAN circuits.

• The car audio system with an AVC-LAN circuit has a diagnostic function.

• Each component has a specified number (3digit) called a physical address. Each function has a number (2-digit) called a logical address.

7. Communication system outline

(a) Components of the navigation system communicate

with each other via the AVC-LAN.

(b) The radio and navigation assembly has enough

resistance (60 to 80 Ω) necessary for communication.

LAN circuit, communication is interrupted and the navigation system will stop functioning.

8. Diagnostic function outline

(a) The audio system has a diagnostic function (the

result is indicated on the master unit).

(b) A 3-digit hexadecimal component code (physical

address) is allocated to each component on the AVC-LAN. Using this code, the component in the diagnostic function can be displayed.

9. "Bluetooth" outline

(a) "Bluethooth" is a trademark owned by Bluetooth

SIG. Inc.

(b) "Bluetooth" is a new wireless connection technology

that uses the 2.4 GHz frequency band. This makes it possible to connect a cellular phone ("Bluetooth"

compatible phone assembly (the "Bluetooth" system is built in), and use the handsfree function of the cellular phone,

(b) Service area

(1) The service areas of AM and FM broadcasts are

vastly different. Sometimes an AM broadcast can be received very clearly but an FM stereo cannot. FM stereo has the smallest service area, and is prone to pick up static and other types of interference such as noise.

HINT: In addition to static, other problems such as "phasing", "multipath", and "fade out" exist. These problems are not caused by electrical noise, but by the radio signal propagation method itself.

E108734E01

Phasing

E108735E01

Ionosphere

I100011E02

(1) Phasing

AM broadcasts are susceptible to electrical interference and another kind of interference called phasing. Occurring only at night, phasing is the interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off the ionosphere and the other signal is received directly from the transmitter.

NS–20

Multipath

Fade Out

NAVIGATION – NAVIGATION SYSTEM

(2) Multipath

Multipath is a type of interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off buildings or mountains and the other signal is received directly from the transmitter.

I100012E02

(3) Fade out

Fade out is caused by objects (buildings, mountains, and other such large obstacles) that deflect away part of a signal, resulting in a weaker signal when the object is between the transmitter and vehicle. High frequency radio waves, such as FM broadcasts, are easily deflected by obstructions. Low frequency radio waves, such as AM broadcasts, are much more

I100013E02

difficult to deflect.

(d) Noise problem

Technicians must have a clear understanding about each customer's noise complaint. Use the following table to diagnose noise problems.

Radio Frequency Noise Occurrence Condition Presumable Cause

AM Noise occurs in a specified area Foreign noise

An identical program transmitted from

AM Noise occurs when listening to an intermittent broadcast

AM Noise occurs only at night Music beat from a distant broadcast FM Noise occurs while driving in a specified area

multiple towers can cause noise where the signals overlap

Multipath or phasing noise resulting from a change in FM frequency

HINT: If the noise does not match the examples above, refer to the descriptions about phasing and multipath.

SYSTEM NORMAL CONDITION CHECK

1. CHECK NORMAL CONDITION

(a) If the symptom is applicable to any of the following,

it is intended behavior, and not a malfunction.

Symptom Answer

A longer route than expected is chosen. Even when distance priority is high, the shortest route is not shown. Some paths may not be advised due to safety concerns.

When the vehicle is put into motion immediately after the engine starts, the navigation system deviates from the actual position.

When running on certain types of roads, especially new roads, the vehicle position deviates from the actual position.

Depending on the road conditions, the radio and navigation assembly may determine that a longer route is quicker.

If the vehicle starts before the navigation system activates, the system may not react.

When the vehicle is driving on new roads not available on the map disc, the system attempts to match it to another nearby road, causing the position mark to deviate.

(b) The following symptoms are not a malfunction, but

are caused by errors inherent in the GPS, gyro sensor, speed sensor, and radio and navigation assembly. (1) The current position mark may be displayed on a

nearby parallel road.

(5) When the vehicle runs on a steep hill, the

current vehicle position mark may deviate from the correct position.

I100070

(6) When the vehicle makes a continuous turn of

360, 720, 1,080, etc. degrees, the current vehicle position mark may deviate from the correct position.

I100071

(7) When the vehicle moves erratically, such as

constant lane changes, the current vehicle position mark may deviate from the correct position.

I100072

(8) When the ignition switch is turned on (ACC or

IG) on a turntable before parking, the current vehicle position mark may not point in the correct direction. The same will occur when the vehicle comes out of parking.

(9) When the vehicle runs on a snowy road or a

mountain path with the chains installed or using a spare tire, the current vehicle position mark may deviate from the correct position.

I100074

(10)When a tire is changed, the current vehicle

position mark may deviate from the correct position. HINT:

• Diameter of the tire may change, causing a speed sensor error.

• Performing the "tire change" in calibration mode will allow the system to correct the current vehicle position faster.
