METHOD FOR OPERATING A BRAKING SYSTEM, CONTROL UNIT AND BRAKING SYSTEM

Abstract: a method for operating a braking system for a motor vehicle. the braking system includes at least one hydraulically actuatable wheel brake, a controllable pressure-generating device for providing a hydraulic pressure in a brake circuit including the at least one wheel brake, and an actuating element that is actuatable by a driver and is intended for specifying a braking request. the brake circuit is assigned a sensor for detecting an actual hydraulic pressure in the brake circuit. the pressure-generating device is controlled depending on the braking request and the actual hydraulic pressure detected in the brake circuit by the sensor. an efficiency value of the pressure-generating device is ascertained and stored depending on the braking request and the detected actual pressure. in the event of a function error of the sensor, the pressure-generating device is controlled at least depending on the braking request and the stored efficiency value.
