Abstract: A calibration method is specified for an electro-hydraulic motor vehicle brake system. The brake system comprises a piston for building up a hydraulic pressure in the brake system, a first actuator having an electric motor, and a second actuator having a brake pedal interface. The first actuator and the second actuator are both capable of activating the piston, wherein a first sensor system detects a change in state of the first actuator, and a second sensor system detects a change in state of the second actuator. The calibration method starts with actuation of the electric motor, in order to activate the piston by means of the first actuator, wherein the second actuator follows the piston activation. During the piston activation, a first signal which is generated by the first sensor system and which permits a conclusion to be drawn about an extent of the piston activation, as well as a second signal which is generated by the second sensor system are detected.

Abstract: The present invention relates to an apparatus for determining a pedal displacement of a brake pedal for a vehicle brake system. In said case, a magnetic element disposed on a piston in the interior of a housing of a brake cylinder is used, which cooperates with a sensor element disposed at the outside of the brake cylinder in order to detect positions and movements of the piston. As positions and movements of the piston connected to the magnetic element correspond directly with positions and movements of a brake pedal connected rigidly and directly thereto or characterize said positions and movements in the case of an indirect connection to the brake pedal, it is possible on the basis of positions and movements, which are determined for the piston, to infer the underlying pedal displacement of the brake pedal.
