Abstract
A method for operating a parking brake which has an actuator with an actuating element and an electric motor, the electric motor is operatively connected to the actuating element in order to displace the latter, the electric motor is actuated in order to displace the actuating element by a predefined movement travel, and an actual movement travel of the actuating element is monitored in order to actuate the electric motor. The method includes determining the actual movement travel of the actuating element in a manner which is dependent on a motor current and/or a motor voltage of the electric motor.
Claims7
A method for operating a parking brake including an actuator having an adjusting element and an electric motor operatively connected to the adjusting element, the method comprising:
- controlling the electric motor in order to displace the adjusting element along a predetermined movement path;
- monitoring an actual movement path of the adjusting element so as to control the electric motor;
- and
- determining the actual movement path of the adjusting element in dependence upon a motor current of the electric motor and/or a motor voltage of the electric motor.
A device for operating a parking brake, comprising:
- an actuator having an adjusting element configured to be displaced along a predetermined movement path, and an electric motor operatively connected to the adjusting element and configured to displace the adjusting element along the predetermined movement path;
- and
- a control device operatively connected to the actuator and configured to
- control the electric motor in order to displace the adjusting element along the predetermined movement path,
- monitor an actual movement path of the adjusting element so as to control the electric motor, and
- determine the actual movement path of the adjusting element in dependence upon a motor current of the electric motor and/or a motor voltage of the electric motor.
