Title: DEVICE AND METHOD FOR MONITORING A BRAKE-APPLYING ELECTROMECHANICAL DEVICE FOR VEHICLE BRAKES
Abstract:
The invention concerns a device and a method for monitoring an electromechanical brake-applying device designed for motor vehicle brakes. Said electromechanical brake-applying device comprises the following elements: a control member comprising an electric motor (29) provided with electric supply; preferably a cylinder with accumulator (1) including a spring (5) which can be tensioned by the control member and serving to actuate a plunger (7) to apply and release the vehicle brake. The monitoring device (39) has a detecting unit (43) for establishing an intensity and/or voltage curve of the current flowing in the electric supply (42) whereof the output is connected to an evaluating unit (45) for comparing the values of said intensity and/or voltage curve with previously stored threshold values and/or a previously stored threshold value characteristic.
