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: A sensor assembly for use with a master cylinder is described. The master cylinder comprises an input-side activation element to which a signal transmitter element is coupled. The sensor module comprises a travel sensor for sensing travel carried out by the activation element, and a position sensor for sensing when a predefined position of the activation element is reached.

Abstract: A sensor module for use with a master cylinder of a brake system is described, wherein the master cylinder has an input-side activation element and an underpressure region for communicating with an underpressure brake booster. The sensor module comprises an underpressure sensor for detecting an underpressure in the underpressure region of the master cylinder as well as at least one further sensor for detecting a signal transmitter which is rigidly coupled to the activation element. The underpressure sensor and the at least one further sensor are accommodated in a housing of the sensor module. An opening in the housing permits communication between the underpressure sensor and the underpressure region of the master cylinder.
