Abstract
A differential travel sensor for a braking system of a vehicle includes: a field generation component, with the aid of which a first electrical and/or magnetic field having a predefined intensity distribution is generated in a spatial axis system fixedly definable with respect to a first body which is a driver brake force transmission component or an actuator force transmission component; and a sensor unit detecting at least one intensity variable of a second electrical and/or magnetic field generated due to an interaction of the first electrical and/or magnetic field with a second body, the second body being different from the first body and being the driver brake force transmission component or the actuator force transmission component.

15. A differential travel sensor for a braking system of a vehicle, comprising:
-
a field generation component situated one of on or adjacent to one of (i) a driver brake force transmission component of the braking system or (ii) an actuator force transmission component of the braking system, wherein the field generation component generates at least one of a first electrical field and a first magnetic field having a predefined intensity distribution in a spatial axis system defined fixedly with respect to a first body which is one of the driver brake force transmission component or the actuator force transmission component; a sensor unit situated on the vehicle in such a way that the driver brake force transmission component and the actuator force transmission component are displaceable in relation to the sensor unit, wherein the sensor unit determines at least one intensity variable of at least one of a second electrical field and a second magnetic field generated due to an interaction of the at least one of the first electrical field and the first magnetic field with a second body which is one of the driver brake force transmission component or the actuator force transmission component, the second body being different from the first body; and an analysis unit which determines, by taking into consideration the at least one intensity variable, an item of output information with respect to a differential travel present between the driver brake force transmission component and the actuator force transmission component. - View Dependent Claims (16, 17, 18)
