  • Patent number: 11447116
    Abstract: A method (200) for detecting the clearance of a brake (100) of a motor vehicle, in particular a utility motor vehicle, includes the following steps: reading measurement signals of a wear sensor (115) disposed on the brake (100), determining an output signal value that is representative of the non-actuated state of the brake from the measurement signals, determining an event signal value that is representative of the braking state of the brake from the measurement signals, and determining the clearance from the difference between the event signal value and the output signal value, wherein the measurement signals of the wear sensor are examined for the presence of a characteristic signal oscillation that arises as a result of bringing into contact the brake lining with the counterpart thereof that is to be braked. A controller (10) carries out the method on a brake (100).
