Abstract
A method for operating a vehicle brake having a brake servo unit and a parking brake actuator. In the case of a failure of the brake servo unit, the distance between brake linings of the vehicle brake and brake disk is reduced by actuating the parking brake actuator.
Claims9
A method for operating a hydraulic vehicle brake which is equipped with a brake servo unit including a hydraulic pump for generating a brake force applied on a wheel brake unit in response to pedal actuation, a parking brake function being additionally provided by a parking brake actuator, the method comprising:
- in the case of one of a partial failure and a complete failure of the brake servo unit, reducing a separation distance between brake linings of the wheel brake unit and a brake disk to an adjusted non-zero separation distance by actuating the parking brake actuator.
A regulating or control unit for implementing a method for operating a hydraulic vehicle brake which is equipped with a brake servo unit including a hydraulic pump for generating a brake force applied on a wheel brake unit in response to pedal actuation, a parking brake function being additionally provided by a parking brake actuator, comprising:
- means for reducing, in the case of one of a partial failure and a complete failure of the brake servo unit, a separation distance between brake linings of the wheel brake unit and a brake disk to an adjusted non-zero separation distance by actuating the parking brake actuator.
A vehicle brake system in a vehicle, comprising:
- a regulating or control unit for implementing a method for operating a hydraulic vehicle brake which is equipped with a brake servo unit including a hydraulic pump for generating a brake force applied on a wheel brake unit in response to pedal actuation, a parking brake function being additionally provided by a parking brake actuator, the regulating or control unit including:
- means for reducing, in the case of one of a partial failure and a complete failure of the brake servo unit, a separation distance between brake linings of the wheel brake unit and a brake disk to an adjusted non-zero separation distance by actuating the parking brake actuator.
