SYSTEM AND METHOD FOR CONTROLLING PARKING BRAKE USING BACK ELECTROMOTIVE FORCE

An electromechanical brake system may comprise: an electric motor mechanically connected to a brake pad assembly to apply a parking brake; and a controller electrically connected to the electric motor. The controller is configured to, in response to a voltage associated with a back electromotive force generated by rotation of the electric motor caused by movement of the brake pad assembly, check a status of the parking brake and/or control the electric motor to re-apply the parking brake. A force of the parking brake re-applied in response to the voltage associated with the back electromotive force generated by the electric motor may be larger than a force of the parking brake previously applied before re-applying the parking brake.
