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.
