Abstract:
1. A method for hydraulic boosting of an electric parking brake of a vehicle comprising providing at least one brake actuator ( 2 c , 2 d ), which for electric and hydraulic operation of the at least one brake actuator ( 2 c , 2 d ) includes a hydraulic service brake function and an electric parking brake function, wherein an application force (F) electrically generated with the parking brake function is superimposed with a boosting brake force generated by subjecting the brake actuator ( 2 c , 2 d ) to a hydraulic boosting brake pressure (P u ) provided by the service brake function, operating of the parking brake to generate a specified application force, detecting the application force generated by the brake actuator ( for a measurement of the actual value (I performing by means of the parking brake function a further application function for further application of the brake actuator (
