Introduction to DSC

Dynamic Stability Control (DSC II)

Dynamic Stability Control II (DSC II) is a further development to the ABS/ASC+T5 traction

control system. DSC I was introduced in other markets on the E32 and E31 vehicles with

the M70 engine.

The DSC system is designed to improve the lateral stability of the vehicle in all driving situ-

ations. Whereby ASC+T is primarily designed for longitudinal stability and providing the

optimum traction for driving off, DSC adds lateral stability control to the already proven sys-

tem.

For any given turning angle and speed of the vehicle, there is a set difference between the

rotational speeds of the front wheels. If the rotational speeds of the front wheels vary from

this set difference, it means the vehicle is understeering or oversteering through the turn.

This could lead to an unstable condition and possible loss of control.

The DSC system is designed to monitor this rotational difference and react to any changes

or deviations that might possibly occur. The DSC provides ASC control for the vehicle while

driving through corners or any time the vehicle is not moving straight ahead.

In essence, the ASC+T5 becomes a Dynamic Stability Control System with this added fea-

ture.
