Abstract: A method for determining defects of an automated parking brake for a motor vehicle with at least one brake device includes detecting damage to the parking brake on the basis of a time profile of a variable representing an output torque of a parking brake actuator. The parking brake includes the parking brake actuator configured to be activated. The detection of the damage includes analyzing the time profile of the variable representing the output torque of the parking brake actuator during a first phase of an activation process of the parking brake for the identification. The activation process of the parking brake has at least two phases. A first phase of the activation process includes a no build up or reduction of a clamping force between at least one brake lining and a brake disk. A second phase includes a build up or reduction of the clamping force.

Abstract: A method for operating a wheel braking device having an electrically motorized actuator, wherein the actuator comprises an electric motor and an actuator element that can be moved by means of the electric motor. The actuator element is moved into a brake application position to actuate the wheel braking device and moved into a brake release position to release the wheel braking device. A movement travel of the actuator element is monitored while releasing the wheel braking device. The electric motor is switched from a control operation into a free-running operation during a release process and a free-running voltage is determined and that a minimum duration of movement of the actuator element for achieving the release position is calculated based upon the determined free-running voltage and is compared with a measured duration of movement of the actuator element to perform a plausibility check of the movement travel.
