Vehicle tracking function sequence
The vehicle tracking function differentiates from the routine type of position finding only through the two following triggering variations; the subsequent
function sequence is identical:
^
Vehicle theft notification from customer per telephone to the CAC
^
Anti-theft alarm system active for > 30 s
Vehicle theft notification from customer per telephone to the CAC
Following a theft notification by telephone, the CAC checks the customer's query and legitimization and if the data matches up it issues an initiation
command to the vehicle.
Anti-theft alarm system active for > 30 s
If the anti-theft alarm system is triggered, the emergency call system control unit receives an "ATA alarm" message in the following way:
^
Front SAM control unit with fuse and relay module
^
Diagnostic CAN
The initiation command or the "ATA alarm" message is received or sent by the communication module integrated into the emergency call system control
unit via the multifunction antenna in the following way:
^
Discrete line
^
Frequency switchover control unit (N96), with code (389) Mobile phone preinstallation with universal interface, USA/ Canada
^
Discrete line
The emergency call system control unit activates the GPS position finding and also the voice connection to the vehicle. Following this, the
communication module integrated into the emergency call system control unit sends the position data to the service provider in the same way as the
initiation command or "ATA alarm" message. This is done cyclically and for the following events:
^
When a specific distance is exceeded
^
Recognition of damage or manipulation to the vehicle
^
"Circuit 15 ON" or "circuit 15 OFF" (ignition switched on or off)
The CAC forwards the location of the vehicle to the responsible command staff (e.g. police). The command staff can then decide whether to listen in or
talk to the drive
Vehicle tracking can only be deactivated by the CAC.
If the multifunction antenna malfunctions (e.g. defective because of rollover), the emergency call system control unit automatically uses the emergency
call system antenna (A2/52) to receive and transmit the initiation command or the "ATA alarm".
