Electromechanical braking system i.e. parking brake system, for use in motor vehicle, has control unit controlling motion of motor, where evaluation within unit is performed based on input parameter for diagnostic method

摘要

The system i.e. parking brake system (1), has an actuator (5) driven by a direct-current motor (28), which is operated in two opposite rotating directions. A control unit (10) controls or regulates motion of the direct-current motor. Evaluation within the control unit is performed based on an electrical parameter e.g. electric current, lying at the direct-current motor during application or releasing of the actuator. The electrical parameter is drawn as an input parameter for a diagnostic method to evaluate electric supply quality of the direct-current motor. An independent claim is also included for a method for operating an electromechanical braking system.
