GF82.95-P-2021FLU Vehicle Tracking, Function

GF82.95-P-2021FLU Vehicle Tracking, Function
- with CODE (359) TELE AID emergency call system

Vehicle tracking function requirements
^ Circuit 30g On
^ Emergency call system authorized and operating properly
^ The vehicle-related vehicle tracking service is authorized separately
^ The driver is registered and authorized with the service center
^ One mobile phone network is available in sufficient strength and quality

Vehicle tracking, general
The following points are vehicle tracking objectives:
- Retrieval of stolen or misappropriated vehicles
- Fast assistance in event of a "car jacking"

The vehicle tracking function consists of the following subfunctions:
^ Function sequence, "Antitheft alarm"
(with code (551) Antitheft alarm system (ATA [EDW]))
^ Function sequence for vehicle theft telephone message from driver to police and then to service center
^ Function sequence, "vehicle tracking"

Function requirements, "Antitheft alarm" (with code (551) Antitheft alarm system (ATA [EDW]))
^ Anti-theft alarm system (ATA) active for t > 30 s

Function sequence, "Antitheft alarm" (with code (551) Antitheft alarm system (ATA [EDW]))
If the anti-theft alarm system is triggered, the emergency call system control unit (N123/4) receives an "ATA alarm" message over the following via the following route:
- Rear SAM control unit with fuse and relay module (N10/2)
- Interior CAN (CAN B)
- Front SAM control unit with fuse and relay module (N10/1)
- Diagnostic CAN (CAN D)

The "ATA alarm" message is transmitted by the communication module integrated into the emergency call system control unit to the service center via the following route:
- Direct line
- Multifunction antenna (A28/11)

The service center receives the "ATA alarm" message and advises the driver by telephone that the ATA alarm has been triggered. "Vehicle tracking" will not yet be activated by the service center.

Function requirements, vehicle theft telephone message from driver to police and then to service center
^ The driver was informed by the service center that the ATA alarm has been triggered (with code (551) Anti-theft alarm system (ATA))
^ Driver notices that vehicle has been stolen

Function sequence for vehicle theft telephone message from driver to police and then to service center
If the driver has been informed by the service center that his/her vehicle has been stolen or if the driver himself/herself notices that the vehicle has been stolen, it is first necessary for the driver to report the theft to the police. The driver receives a number from the police, which confirms that the vehicle theft has been reported. The driver calls the service center on the telephone and passes on this number. The service center checks the inquiry and the driver's authorization.

Function requirements, "vehicle tracking"
^ Vehicle reported as stolen by driver, by telephone, to police and then to service center and authorization with the service center
^ An emergency call system control unit communication module authorized for the corresponding vehicle-related service is configured ex-factory with the telephone number of the corresponding service provider
^ A higher-priority vehicle-related service is not active
^ No faults in Global Positioning System (GPS) antenna system and signals present from at least three GPS satellites

Function sequence, "vehicle tracking"
After reporting the theft to the service center and authorization with the service center, an initiation command is sent to the vehicle.
The initiation command is received by the communication module integrated into the emergency call system control module via the following route:
- Multifunction antenna
- Direct line

The emergency call system control unit then activates the GPS position finding and also the voice connection to the vehicle. Then the communication module integrated into the emergency call system control unit sends the position data to the service provided in the same manner as the "ATA alarm" message.

The position data is transmitted cyclically and for the following events:
- When a specific distance is exceeded
- Detection of damage or manipulation to the vehicle
- Circuit 15 On or circuit 15 Off (ignition switched on or off)

The service center forwards the location of the vehicle to the responsible command staff (e.g. police). The command staff can then decide whether or not to speak to the driver.

Vehicle tracking can only be deactivated by the service center.

In the event of a multifunction antenna failure (e.g. defective because of rollover) the emergency call system control unit automatically uses the emergency call system antenna (A2/52) to transmit the mobile phone signals.
