- Implementation of the nominal values of the ICM control unit (for DCC/ACC Stop&Go)
- Generation of signals from drive forces (for DCC/ACC Stop&Go)
|
| 11 |
Dynamic Stability Control (DSC) |
- Implementation of the nominal values of the ICM control unit (for DCC/ACC Stop&Go)
- Monitoring of stationary vehicle with ACC Stop&Go active
- Implementation of the functions of the Adaptive Brake Assistant at the request of the ICM control unit (precharging of the brake system and reduction in the threshold of the hydraulic Brake Assistant)

| 14 |
Other output signals |
- Calling up the Assistant window for setting the collision warning time (on CIC)
|
| 15 |
Control functions |
- The control functions for both DCC and ACC Stop&Go are integrated into the ICM control unit
|
| 16 |
Status control |
- ICM controls the status of DCC and ACC Stop&Go in accordance with received operating signals (and other signals). The status is needed outside the ICM control unit specifically for display information in the instrument cluster and in the head-up display
- The activation and deactivation of the collision warning is also controlled by the ICM.
