In a method for setting the clamping force exerted by a parking brake, which force is applied by an electric motor-based braking apparatus and, if necessary, by an additional braking apparatus, during an actuation phase of the electric motor-based braking apparatus, the motor resistance and the motor constant are determined from the present motor voltage, the present motor current, and the present motor rotation speed, and the clamping force achievable by the electric motor-based braking apparatus is ascertained therefrom. If the electric motor-based braking force does not reach a required target clamping force, an additional braking force is generated by the additional braking apparatus.
