Function requirements for initiating automatic emergency call
^
Circuit 15R
Function sequence for initiating automatic emergency call
The emergency call system control unit receives the crash signal from the supplemental restraint system control unit via a direct line. Simultaneously, the
emergency call system control unit receives the crash signal (redundant) and the crash level from the supplemental restraint system control unit via the
following route:
-
Chassis CAN (CAN-E)
-
Front SAM control unit with fuse and relay module (/)N10/1
-
Diagnostic CAN (CAN D)
Function sequence for transmission of emergency call data and communication with the service center
After a manual or automatic emergency call has been triggered, the emergency call system control unit completes a voice connection to the service
center.
After the service center replies with a special tone, the emergency call system control unit automatically sends an SMS with the following data to the
service center over the integrated communication module:
-
Vehicle position, direction of ravel and history
-
Vehicle data and crash analysis (accident severity)
The communication module integrated into the emergency call system control unit transmits and receives the mobile phone signals or data in the
following way:
-
Direct line
-
Frequency switchover control unit (N96), with code (389) Mobile phone preinstallation with universal interface, USA/ Canada, and direct line
-
Multifunction antenna (A28/11)
If connection to the service center cannot be established when an automatic emergency call is triggered, a voice connection is automatically set up using
the emergency number "911" and it is then necessary to communicate the listed data verbally.
If a manual or automatic emergency call is active, this is indicated by one of the two red light-emitting diodes (LED) integrated into the emergency call
system button flashing. This is also indicated in the instrument cluster (A1) and on the Audio/COMAND display (A40/8).
In the event of a manual or automatic emergency call, other vehicle-related services (e.g. MB-Info call) and, on vehicles with code (389) Mobile phone
preinstallation with universal interface, USA/Canada, any active mobile phone connections are interrupted.
In the event of a multifunction antenna malfunction (e.g. defective because of rollover) the emergency call system control unit automatically uses the
emergency call system antenna (A2/52) to transmit mobile phone signals or data.
