Dynamic Cruise Control (DCC): Function
The new Dynamic Cruise Control (DCC) with brake function maintains the set speed at a constant level even on downhill gradients.
- Accelerating to the set speed - Engine intervention via the DME (acceleration of approx. +1.2 m/s2 )
- Decelerating to the set speed - Independent brake intervention via the DSC (DCC achieves a maximum deceleration of -2.5 m/s2 )
- Lateral acceleration is restricted to max. 4.0 m/s2
In order to realize these functions the system requires the use of the Longitudinal Dynamics Management (LDM), which is used to supply data/driver request signals to the DME.
IMPORTANT:
Cruise control does not relieve the driver of his personal responsibility. Cruise control is a comfort system. Adjustments by the driver will always have a higher priority than cruise control.
The driver should decide whether (and how) the system is used based on road and traffic conditions and visibility.

When the cruise control is active, the brake lights are actuated during automatic braking (required by law). If automatic braking is actuated, a signal is sent from the DSC to the Footwell Module (FRM).
