Dynamic stability control DSC Mk60: Introduction

The E85 is equipped as standard with dynamic stability control Mk60. DSC Mk60 was first introduced on the E46 in 09/2000, but without DTC function (DTC = dynamic traction control).

From 09/2000 to 09/2001 DSC in the E46 was equipped with the ADB function (automatic differential brake). From 09/2001, DSC Mk60 has been available in the E46 with DTC function.

System supplier for DSC Mk60 is Continental Teves. For System Overview, refer to SYSTEM OVERVIEW  .

DSC is a dynamic driving system that maintains driving stability.

DSC optimizes:

• driving stability when pulling away, accelerating and braking
• traction

In addition, DSC recognizes unstable driving situations such as understeering or oversteering.

Within the limitations of the laws of physics, DSC helps to keep the vehicle on a safe course.

To do this, DSC must know the following parameters of driving dynamics:

• yaw rate as a measure of rotary movement of the vehicle around the vertical axis
• lateral acceleration as a measure of the coefficient of friction with the road surface
• road speed

In addition, the driver's requirements are recognized from the angle of the steering wheel and the pressure on the brake pedal. Moreover, speed sensors deliver information about the speed of each individual wheel. The actual situation in which the vehicle is currently moving is computed from the available data. The actual situation is compared to reference data computed by the DSC control unit.

If the actual data differ from the reference data, DSC is activated and intervenes in the braking system or in the engine control.

The advantages: 

The active intervention of DSC in the engine control and brakes provides outstanding driving stability and traction in all driving situations. DSC counters all negative dynamic driving forces and so creates a maximum degree of active safety within the limitations of the laws of physics.

DSC thus enhances driving comfort by allowing more relaxed driving.
