Functional networking of the suspension control systems
The signals of the Integrated Chassis Management (ICM) and the Dynamic Stability Control (DSC) interact functionally for the distribution of the locking torque at the rear axle.
The Dynamic Stability Control (DSC) remains the deciding control unit for decisions regarding the stabilization of the drivability. In this case, the Dynamic Stability Control (DSC) request a defined locking torque for the stabilization of the vehicle. The opening of the lock is thus suppressed. In the process, the Integrated Chassis Management (ICM) makes signals available via the longitudinal acceleration, lateral acceleration and yaw rate.
