Abstract: In a method for operating a force-sensor-less electromechanical service brake in a brake system of a vehicle, a current value of a braking contact point and a current profile of a force-displacement characteristic of the electromechanical service brake are determined as a function of the total rotation angle of a shaft of an electric motor of the electromechanical service brake. These values are determined in regular driving operation of the vehicle. In the case of a braking request, the electric motor is activated in accordance with the current value of the braking contact point and the current profile of the force-displacement characteristic in order to satisfy the braking request. The electric motor has a detection element, which detects the total rotation angle of the shaft and a rotation rate of the electric motor.
