Abstract: In a method for setting the clamping force, which is exerted by a parking brake, a portion of which clamping force is at least partially generated by an electromechanical braking device having an electric actuator, and another portion is additionally generated by an additional braking device, as needed, the actual force curve is determined and compared to a characteristic, defined force curve to determine the magnitude of the electromechanical clamping force to be supplied by the electric actuator. If the actual force curve corresponds to the characteristic force curve, then, in addition to the electromechanical clamping force, an additional clamping force of the additional braking device is also taken into account for obtaining the setpoint clamping force.
