Abstract:
1. A method for setting a clamping force applied by a parking brake, the method comprising: regulating, by a control unit, a first parameter of the electric actuator to a defined value, wherein regulation of the parameter occurs while an auxiliary clamping force is generated by the parking brake, wherein the parking brake includes an electromechanical brake device having an electric actuator for generating an electromechanical clamping force, and an auxiliary brake device which is additionally activated for generating the auxiliary clamping force; and simultaneously setting, by the control unit, a first state variable of the auxiliary brake device which determines the auxiliary clamping force to a setpoint value without feedback control; wherein the auxiliary clamping force of the auxiliary brake device is activated by the control unit when the state variable of the actuator lies outside a defined value range.
