    摘要： 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 and 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. Said method comprises the following steps: a) at least one anti-hysteresis pulse during which a current is set far below or far above the operating current in the valve is temporarily applied to the solenoid valve; b) the anti-hysteresis pulse is applied at the desired operating current before or during controlled operation, particularly each time before the pressure is increased or reduced; and c) the duration of the anti-hysteresis pulse is limited in such a way that the anti-hysteresis pulse has largely no influence on the brake pressure.

    摘要： The invention relates to a method for hydraulically boosting an electric parking brake of a vehicle, said brake comprising at least one brake actuator (2c, 2d). Said vehicle has a hydraulic service brake function and an electric parking brake function for electrically and hydraulically actuating the at least one brake actuator (2c, 2d), wherein an application force (F) that is electrically generated by the parking brake function is superimposed on a boosting brake force that is generated by applying a hydraulic boosting brake pressure (P
    u ) provided by the service brake function to the brake actuator (2c, 2d). According to the invention, when the parking brake is actuated in order to generate a predetermined application force, the application force generated by the brake actuator (2c, 2d) is detected by means of a measured variable (I) representing the value of the application force as the actual value (I
    ist ), if an actual value (I
    ist ) of the measured value (I) is smaller than a first target value (I
    1 ,
    soll ) representing a first target force value (F
    1 ,
    soll ) of the application force, a hydraulic boosting brake pressure (P
    u ) corresponding to a predetermined target boosting brake pressure value (P
    u ,
    soll ) is applied to the brake actuator (2c, 2d), and by means of the parking brake function a tension adjustment function for adjusting the tension of the brake actuator (2c, 2d) to which the hydraulic boosting brake pressure (P
    u ) is applied is carried out in order to achieve the predetermined application force.
