Abstract
The invention relates to a process and control circuits for generating defined actuating forces for a brake that is actuated electrically by means of an actuator or electric motor, wherein a first relationship exists between the actuator position and the torque generated by the actuator when the brake is applied and a second relationship exists between the actuator position and the torque generated by the actuator when the brake is released, defining such relationships make it possible to determine the actuating forces occurring during operation without any additional sensors. For this purpose, the present invention proposes that the actuator torques resulting from the first and second relationships be evaluated for determining the efficiency.
