Abstract
A method for determining a speed using a measurement-sensor in a vehicle, the measurement-sensor including at least one coil and a ferromagnetic-transmitter-element, including: changing the inductance of the coil, using an inductive-speed-sensor having at least the coil and the ferromagnetic-transmitter-element; recording a change in the coil inductance, and determining the speed based on the changed coil inductance; in which in each case one inductive-speed-sensor is a wheel-speed-sensor for at least two vehicle wheels, and in which a reversal of the direction of movement of the ferromagnetic-transmitter-element as to the coil or a reversal of the direction of travel of the vehicle from forward travel to reverse travel or from reverse travel to forward travel is recognized based on at least one temporal-phase-offset of the temporal-profiles of the inductances recorded by the wheel-speed-sensors of the at least two wheels. Also described is a related driver assistance system and vehicle.
