TELE AID, general
The name TELE AID stands for TELE MATIC A LARM I DENTIFICATION ON D EMAND. TELE AID is an automatic emergency call system using the availability of new technologies such as vehicle location finding via satellite and wide distribution of mobile telephone network for reducing accident causes (rescue time reduction). Emergency calls and precise location description are automated by TELE AID and therefore do not depend on incorrect human behavior in stress situations.
Information processing of systems associated to TELE AID is performed via conventional wiring and vehicle's own bus systems (CAN and D2B = digital data bus or fiber optic cables).
TELE AID includes three services:
- TELE AID emergency call
- TELE AID telediagnosis
- TELE AID info call.
Function sequence for a TELE AID emergency call
A TELE AID emergency call can be actuated automatically or manually.
The following actuation procedures should be distinguished:
- Automatically,
- by the restraint system control unit (N2/7)
OR
- by the external tilting cone sensor (B66).
- by the restraint system control unit (N2/7)
- Manually,
- by operating the SOS pushbutton switch (S93/3)
If an alarm is triggered, the telephone transmitter/receiver unit and TELE AID, D2B (A35/17) sets up an emergency call telegram containing information on the accident severity, vehicle identification, vehicle positioning and type of alarm actuation.
The emergency call telegram is transmitted via the vehicle telephone equipment (digital network).
The service provider number to be dialed is stored on the SIM card (TELE AID SIM) integrated in the CTEL and TELE AID transmitter/receiver, D2B (A35/17), and is dialed automatically by the system. If the CTEL antenna (A2/22) is faulty, a switchover is made automatically to the TELE AID backup antenna (A2/50).
If the power supply is interrupted (e.g. battery failure) the system is able to switch automatically over to an additional battery (G1/1).
When the vehicle battery is disconnected for repair purposes, for example, the system switches automatically over to the additional battery (G1/1) when the telephone system is not set to the service mode.
The emergency call telegram is received and decoded by the service provider. The position information that it contains is converted into a town and a street name using a street database and relayed to the responsible rescue headquarters (usually the Police) together with other information from the emergency call telegram.
The decoded emergency call telegram is transmitted to the rescue service by the service provider as follows:
- Either via electronic data transmission or
- via a telephone voice connection.
TELE AID emergency call is supplemented by TELE AID telediagnosis and the MB information service.
TELE AID telediagnosis allows assistance to be obtained quickly in the case of a vehicle defect.
Requirements and function sequence for TELE AID telediagnosis are practically identical with the function sequence for a TELE AID emergency call.
If vehicle operational problems occur, the driver can reach the responsible centers via the MB Info.
With a TELE AID service (emergency call, telediagnosis, MB information) a voice connection (via mobile telephone network) is accomplished from the vehicle to the associated service point. Then the required rescue measures are started there.
When initially started the system performs an authorization. To do this a valid SIM (Subscriber Identification Module) card (for TELE AID) must be installed in the telephone transmitter/receiver unit and TELE AID, D2B (A35/17) and a service contract agreed with the corresponding service provider.
A SIM card for the D1 or D2 network can be installed for the TELE AID service (code 855).
Without authorization is not possible to operate a TELE AID service. If no authorization has been obtained or the TELE AID emergency call system is malfunctioning, the SOS pushbutton switch (S93/3) indicator lamp comes on and an error message appears in the instrument cluster (A1) display.
Fault message in the case of TELE AID E-Call
If no authorization has been obtained or the TELE AID telediagnosis/MB information service is malfunctioning, an error message appears also in the instrument cluster (A1) display.
The following structogram indicates, strongly simplified, the sequence of a TELE AID emergency call.
The abbreviations used have the following meaning:
