System Description

NAVIGATION SYSTEM OUTLINE

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.

HINT:

OPERATION DESCRIPTION REFERENCE

Operation	Description
Vehicle Position Calculation	The display and navigation module display calculates the current vehicle position (direction and current position) using the direction deviation signal from the gyro sensor and running distance signal from the vehicle speed sensor, and creates the driving route.
Map Display Processing	The display and navigation module display processes the vehicle position data, vehicle running track, and map data from the map disc
Map Matching	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.
GPS Correction	The vehicle position is matched to the position measured by the GPS. Then, the measurement position data from the GPS unit is compared with the vehicle position and running track data. If the position is very different, the GPS measurement position is used.
Distance Correction	The running distance signal from the vehicle speed sensor includes error caused by tire wear and slippage between the tires and road surface. Distance correction is performed to account for this. The display and navigation module display automatically offsets the running distance signal to make up for the difference between it and the distance data of map. The offset is automatically updated.

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 be received. When only autonomous navigation is used, the mapping accuracy may slightly decline.

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 display and navigation module display.
1. Gyro sensor
  Calculates the direction by detecting angular velocity. It is located in the display and navigation module display.
2. Vehicle speed sensor
  Used to calculate the vehicle running distance.

GPS navigation (satellite navigation)

This method detects the absolute vehicle position using radio waves from a GPS satellite*.

HINT:

*: GPS satellites were launched by the U.S. Department of Defense for military purposes.

SATELLITES DESCRIPTION REFERENCE

Number of Satellites	Measurement	Description
2 or less	Measurement is impossible	The vehicle position cannot be obtained because the number of satellites is not enough.
3	2-dimensional measurement is possible	The vehicle position is obtained based on current longitude and latitude (this is less precise than 3-dimensional measurement).
4	3-dimensional measurement is possible	The vehicle position is obtained based on current longitude, latitude and altitude.

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.

  Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
2. Purpose:
  Recently, car audio systems have rapidly developed and the functions have vastly changed. The conventional car audio system is being integrated with multimedia 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 +B or short to ground is detected in the AVC-LAN circuit, communication is interrupted and the navigation system will stop functioning.
    - The display and navigation module display is the master unit.
RBDS FUNCTION OUTLINE (BROADCAST IN NORTH AMERICA ONLY)
The Radio Broadcast Data System (RBDS) is broadcast through conventional FM radio broadcasts. Even if a vehicle changes locations, the same information can be received from several FM stations without breaks. Information such as song names, traffic information, broadcast station names, etc. can be received.
SDARS SYSTEM FUNCTION OUTLINE (BROADCAST IN NORTH AMERICA ONLY)
Satellite Digital Audio Radio Service (SDARS) is a satellite digital radio broadcast provided by XM Satellite Radio Inc. The broadcast (pay-type) is performed through satellites and terrestrial repeater networks. Several unique channels are available, and even if a vehicle changes locations, the same information can be received without breaks. Information such as song names, broadcast station names, etc. can be received. Also, traffic information can be received and displayed on the navigation screen.

NOTE: To receive an audio-visual pay-type broadcasts, the customer must enter into a pay-type contract with XM Satellite Radio Inc. After entering into a contract, an ID registration is required. Also, if parts are replaced, the ID must be reregistered. Refer to the owner's manual for information on how to register the ID.
COMMUNICATION SYSTEM OUTLINE
1. Components of the navigation system communicate with each other via the AVC-LAN and AVC-LAN plus.
2. The radio receiver assembly has enough resistance (60 to 80 Ω) necessary for transmitting communication signals. This is essential for communication.
3. If a short circuit or open circuit occurs in the AVC-LAN circuit, communication is interrupted and the navigation system will stop functioning.
DIAGNOSTIC FUNCTION OUTLINE
1. The navigation system has a diagnostic function (the result is indicated on the master unit).
2. A 3-digit hexadecimal component code (physical address) is allocated to each component on the AVC-LAN and AVC-LAN plus. Using this code, the component in the diagnostic function can be displayed.
