GF82.95-P-3005RIU Restraint System Control Unit Data, Function
GF82.95-P-3005RIU Restraint System Control Unit Data, Function
- with CODE (359) TELE AID emergency call system
Function requirements
^
Status "Circuit 15R ON"
^
Proper communication with restrain systems control unit (N2/7)
^
Automatic crash recognition including crash level by restraint systems control unit
General
In the event of an accident with airbag actuation, an automatic emergency call (E-Call) is transmitted immediately. An emergency call is sent out
regardless of the severity of the accident.
Function sequence
The emergency call system control unit (N123/4) receives the crash data on the one hand via a discrete line as a digital crash signal from the restraint
systems control unit and, on the other hand, it also receives the data (redundantly) including the crash level as follows:
-
Interior CAN
-
Central gateway control unit (N93)
-
Diagnostic CAN
The restraint systems control unit transmits a LIFE signal every t = 500 ms over the same path as the crash information including crash level. This allows
the emergency call system control unit to permanently monitor communication with the restrain systems control unit and proper function of the crash
recognition.
GF82.95-P-3005RM Restraint System Control Unit Data, Function
GF82.95-P-3005RM Restraint System Control Unit Data, Function
- with CODE (359) TELE AID emergency call system
The emergency call system control unit (N123/4) receives the messages listed below as a digital crash signal from the restraint systems control unit
(N2/7) over a discrete line. This information is also sent redundantly over the diagnosis bus from the central gateway control unit (N93). The central
gateway control unit (N93) receives the message over the Controller Area Network Bus Class B (interior) (CAN-B) from the restraint systems control
unit (N2/7).
