New Driving Stability Control System with Reduced Technical Effort for Compact and Medium Class Passenger Cars

Wheel slip control system have found a remarkable penetration in all car segments. The information on the wheel behavior has lead to further developments which control the brake performance as well as the driving of the car in general.

Latest systems introduced especially on luxury cars use wheel individual brake intervention to ensure vehicle stability under various driving maneuvers within the physical limits.

Such systems use vehicle dynamic sensors and special hydraulics which serve as energy source for the automatic brake application. The technical effort of such systems like the Dynamic Stability Control DSC has limited the installation to upper class cars so far. New approaches are required to allow for a more wide spread penetration.

Optimized hydraulics together with a rational design of the electronics seems to offer a basis for a more cost effective design. As a result of this a new Driving Stability Control Systems DSC was introduced in the 5 series BMW recently and will find its entry in the 3 series very soon. The 12- and 8-cylinder-versions of the 7-series already use DSC as standard.
