System Functions


The dynamic stability control system (DSC) controls longitudinal and transverse dynamics by means of engine and brake system intervention.

Dynamic Stability Control (DSC) incorporates the following functions.

- Anti-lock braking system (ABS)

- Electronic brake force distribution (EBV)

- Cornering brake control (CBC)

- Automatic stability control (ASC)

- Dynamic traction control (DTC)

- Engine drag torque control (MSR)

- Dynamic brake control (DBC)

- Electronically controlled deceleration (ECD) (only in conjunction with ACC)


Note: Yaw-rate control by the Active Front Steering (AFS)

Active Front Steering also influences the vehicle~s yaw characteristics. Consequently, the software in the DSC is modified accordingly in cars fitted with Active Front Steering (for example, 2 DSC sensors).
Dynamic Stability Control (DSC)

The DSC system determines the cars driving status at any given time by processing the signals

from the sensors. This condition is compared with the nominal values derived from a computational model. In this way, the system recognizes incipient instabilities.

The vehicle is stabilized as soon as a deviation overshoots the control threshold stored in the DSC control unit. Stabilization (within the limits imposed by the laws of physics) is achieved by reducing engine power and by braking individual wheels.

DSC interventions override the ABS and ASC functions.

The DSC function can be deactivated by means of the DSC button.
