Abstract: 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.

Abstract: 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.

Abstract: A method for suppressing a lateral rollover tendency of an at least two-axle and at least two-track vehicle, wherein when a first threshold value of a dynamic and/or static quantity correlating with a vehicle lateral acceleration is exceeded, maximum brake pressures are introduced into the wheel brakes of the vehicle as a rollover prevention, with the threshold value representing a value at which a risk of rollover is encountered at a permissible vehicle load of any type; and a second threshold value of a quantity correlating with the vehicle lateral acceleration is provided, at which low brake pressures are introduced, which is lower than the first threshold value, and wherein the quantity correlating with the vehicle lateral acceleration represents a low rollover tendency level.

Abstract: The present invention relates to a method for modifying a driving stability control of a vehicle wherein the input variables essentially composed of the predetermined steering angle (?) and the driving speed (v) are converted into a nominal value of the yaw velocity ({dot over (?)}nominal) on the basis of a vehicle model defined by running characteristics. The nominal value is compared with a measured actual value of the yaw velocity ({dot over (?)}measured), and an additional yaw torque (MG) is calculated in an ESP controller according to the result of the comparison and used to define an ESP intervention which produces an additional yaw torque by way of pressure quantities applied to the wheel brakes of the vehicle.

Abstract: The present invention relates to a method for improving the control behavior and stability under a thermal load of an automotive vehicle control system with brake intervention, such as TCS, BTCS, ESP, etc. In order to reduce the thermal stress on the brake system in a control system without engine interface, some of the control functions that may involve critical thermal loads on the brake system are at least temporarily disabled or allowed only to a limited extent in defined control situations.
