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.

*GPS (Global Positioning System)

Operation	Description
Vehicle Position Calculation	The navigation receiver assembly calculates the current vehicle position (direction and current position) using the direction deviation signal from the gyro sensor and the driving distance signal from the vehicle speed sensor and creates the driving route.
Map Display Processing	The navigation receiver assembly displays the vehicle track on the map by processing the vehicle position data, vehicle driving track and map data from the map disc.
Map Matching	The map data from the map disc is compared to the vehicle position and driving track data. Then, the vehicle position is matched with the nearest road.
GPS Correction	The vehicle position is matched to the position measured by GPS. Then, the GPS measurement position data is compared with the vehicle position and driving track data. If the position is widely different, the GPS measurement position is used.
Distance Correction	The vehicle speed signal includes the error caused by tire wear and slippage between the tires and road surface. Distance correction is performed to account for this. The navigation receiver assembly automatically offsets the signal to make up for the difference between it and the distance data of the 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 cannot receive a signal. When only autonomous navigation is used, however, the mapping accuracy may slightly decrease.

Autonomous navigation
This method determines the relative vehicle position based on the driving track determined by the gyro located in the navigation receiver assembly and the vehicle speed signal.
1. Gyro sensor
  Used to calculate the direction by detecting angular velocity. It is located in the navigation receiver assembly.
2. Vehicle speed signal
  Used to calculate the vehicle driving distance.

GPS^* navigation (Satellite navigation)

This method detects the absolute vehicle position using radio waves from GPS satellites.

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

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

Map matching
The current driving route is calculated by autonomous navigation (according to the gyro sensor and vehicle speed signal) 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.

Service area

Fig 11: Identifying Service Areas Of AM And FM Broadcasts
Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
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.
Radio reception problems
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.
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.
  
  Fig 12: Identifying Radio Phasing & Ionosphere
  Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
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.
  
  Fig 13: Identifying Radio Multipath
  Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
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 less likely to deflect.

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
AM	Noise occurs when listening to an intermittent broadcast	An identical program transmitted from multiple towers can cause noise where the signals overlap
AM	Noise occurs only at night	Signal phasing
FM	Noise occurs while driving in a specified area	Multipath noise resulting from a change in FM frequency
