Abstract
A brake system includes an electromechanical brake having a friction surface, a lining support, an electric motor for moving the lining support, a spring acting on the lining support, and a control and monitoring unit. A control and monitoring unit ascertains from at least one first value ascertained during a first movement of the lining support by the electric motor, an operating behavior value for a real operating behavior of an operating parameter of the relevant brake, and ascertains, by a comparison of the at least one real operating behavior value to at least one stored operating behavior expectation, a correction factor. The brake control system corrects by the one correction factor and activates a regulator of the electric motor using the corrected brake control signal. The control and monitoring unit is performs a calibration by a spring force of the at least one spring during the first movement.
