The ball screw drive comprises a spindle rotatable by the electric motor and a ball screw nut displaceable on the spindle.

With the aid of the signal of the travel sensor, which indicates a displacement position of the actuation piston, a braking force currently applied by the actuation piston to the braking assembly is determined under consideration of the characteristic curve of the spring element.
