PROCESS FOR IMPROVING THE REGULATING BEHAVIOUR OF AN ANTI-LOCK SYSTEMS

摘要

In order to improve the regulating behaviour of an antilock or skid control system, in particular to improve the steerability of a vehicle and the drive stability when braking in a curve, criteria for recognising curves and their orientation are derived from the skidding of the individual wheels of the vehicle. When a curve is recognised, the normal regulation mode for straight driving is changed into a regulation mode for curve driving. The normal regulation mode for straight driving is characterised by an individual regulation of all wheels or by an individual regulation of the front wheels combined with a select-low regulation of the rear wheels. In the regulation mode for curve driving, the mean pressure level of the front wheel at the inner side of the curve is lowered by a predetermined value and the mean pressure level of the front wheel at the outer side the curve is increased by a predetermined value. The mean pressure level of the rear wheels may also be modified in a corresponding manner in vehicles provided with select-low regulation and pairs of valves for each wheel.
