ICM control unit
New: Sensors that used to be installed separately in the DSC sensor are now fitted in the ICM control unit. The ICM control unit uses these sensors to calculate variables that are important for the dynamic handling characteristics of the vehicle at that time:
- Longitudinal acceleration and vehicle inclination in longitudinal direction
- Lateral acceleration and vehicle inclination in transverse direction
- Yaw rate
The ICM control unit is available as a basic version and a high version. The high version differs in that it has:
- A larger microcontroller (required for calculation of the control operation of Integral Active Steering and Active Cruise Control)
- A redundant sensor system for lateral acceleration and yaw rate (safety requirement for Integral Active Steering).
