ICM: Integrated chassis management
Data from ride height sensors at the front and rear axle is directly evaluated by the Integrated Chassis Management (ICM). The automatic headlight beam throw adjustment thus ensures that oncoming traffic is not dazzled. In addition to the sensors, which are there for driving dynamics control, the Integrated Chassis Management includes a longitudinal and a lateral acceleration sensor for impact detection. Two wires provide a direct connection between the Integrated Chassis Management and the Crash Safety Module (ACSM) for transmission of the sensor signals.
The footwell module (FRM) receives the signals from the Integrated Chassis Management (ICM) via the CAN bus. The signal is transferred from FlexRay to the CAN bus in the central gateway module (ZGM).
The Body Domain Controller (BDC) receives the signals from the Integrated Chassis Management (ICM) as a message via the LIN bus.
