Apparatus and method for detecting the thickness of a brake lining |
摘要 |
An apparatus and a method detect the current thickness and thus the wear of a brake lining of a motor-vehicle brake system, which has a wheel-brake actuator at each wheel that actuates the wheel brake and is individually electrically controlled. The wheel-brake actuator contains a hydraulic piston which is moved by an electric motor and is provided with a sensor that detects the brake pressure or brake force as well as with a further sensor that detects the travel of the hydraulic piston. The thickness of the brake lining is determined from signals of the two sensors. To that end, a measurement is made of the travel performed by the hydraulic piston until a predetermined brake pressure is reached.
