Additionally to the already available ASC and ASC+T of the BMW top models newly designed stability control systems will become introduced in the 3-Series and series BMW cars. All these systems are applicable on mechanic and automatic gearbox-equipped cars. Whereas ASC, available at BMW since ’87, is a pure engine-control system, where reduction of engine torque is used to avoid stability-critical situations 0n low-p road surfaces, the latest Automatic Stability Control Systems of BMW (ASC+T) additionally apply active braking to the driven wheels. The engine control of BMW‘s ASC-systems is based on a selected interface structure of engine management and transmission control units. Throttle control as well as active braking is realized differently depending on the respective model range. Whereas the BMW 750i and 850i use bifluid hydraulic units in add-on technique for ASC, ABS-integrated hydraulics in open or semi-open versions will be applied to the other types of the BMW model range. The newly designed ABS-integrated ASC-systems form the basis for further increased penetration of the car market with stability control systems. The different systems described in this paper show remarkable improvements in vehicle stability as well as in traction capability during critical driving situations. Performance data and statistical analysis of test results obtained with ASC-equipped cars prove, that the Automatic Stability Control Systems contribute significantly to improve active safety.
