GF91.60-P-4105-02SK WSS Control Unit, Task
GF91.60-P-4105-02SK WSS Control Unit, Task
- as of 1.6.06
- with CODE (494) USA version
Task
^
Evaluation and voltage supply of:
-
Belt tension sensor (B48/3)
-
Pressure sensor (B48/4)
^
Weight categorization of applied weight (adult, object or child seat)
^
Provision of the weight classification and seat occupation recognition information on the Controller Area Network bus Class B (interior) (CAN-B)
^
Save self-test and faults
After recognizing that the front passenger seat is occupied, the Weight Sensing System (WSS) control unit (N110) uses the detected data from the
pressure sensor (B48/4) and from the belt tension sensor (B48/3) to perform a weight classification for the person, object or child seat.
The data for the weight classification are made available over CAN-B to the restraint systems control unit (N2/7) for precise control of the front
passenger airbag unit.
