Emergency call, general
Emergency call (E-Call) is an automatic emergency call system which uses the availability of new technologies, such as vehicle locating via satellite and
telephone, to minimize the consequences of accident.
The emergency call report as well as the exact description of the location are made possible with E-Call, irrespective of human error in stress situations.
Operating procedure
An E-Call emergency call can be triggered automatically or manually. The following actuation procedures should be distinguished:
Type of triggering, automatic:
^
Restraint systems control unit (N2/7)
^
E-call control unit (A35/8) with integral tilting cone sensor (B66)
Type of triggering, manual:
^
By pressing the SOS pushbutton switch (S93/3)
If an alarm is triggered, an emergency call telegram is put together by the E-call control unit (A35/8) which contains information on the severity of the
accident, on the identification of the vehicle, the vehicle position and on the type of alarm triggering. The emergency call telegram is transmitted via the
vehicle's telephone equipment.
In the event of a defective telephone antenna (A2/22) the system automatically changes over to the emergency call system left backup antenna (A2/54) or
emergency call system right backup antenna (A2/55).
When the connection to the person involved in the accident is successfully completed, an emergency call (telephone voice connection) is passed on to the
rescue headquarters responsible (police, fire department etc.).
