A control valve conditioning method in an electrohydraulic pressure control unit comprising at least one electrically triggered solenoid valve that is controlled in an analog manner. The solenoid valve is operated at a specific operating current according to a functional correlation or characteristic diagram between the valve current and the differential pressure characteristic curve when the pressure is controlled, said functional correlation or characteristic diagram being stored in the pressure control unit. The method comprises the following steps: a) temporarily applying at least one anti-hysteresis pulse to the solenoid valve during which a current is set far below or far above the operating current in the valve; b) applying the anti-hysteresis pulse at the desired operating current before or during controlled operation, and c) applying the anti-hysteresis pulse wherein the duration is limited in such a way that the anti-hysteresis pulse has largely no influence on the brake pressure.

Method for conditioning a control valve

The invention relates to a method for controlling the driving stability of a vehicle, wherein it is determined when a stable or unstable driving behavior prevails whether a tendency to a subsequent unstable driving behavior exists as a result of a highly dynamic inward swerve. In order to provide a method for controlling driving stability, which allows a reaction to predicted unstable driving situations by means of an intervention diminishing or avoiding critical driving situations, the steering force and/or the steering angle of a steering handle is corrected in this case in such a manner that when the steering handle is operated, the driver is assisted in the direction of an understeering vehicle course.
