Distance difference sensor and brake booster device for vehicle brake system, brake system for vehicle, and method for determining distance difference

摘要

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.
