Abstract

A method for determining a speed between a measurement-sensor, including at least one coil and a ferromagnetic-transmitter-element (FEM), including: changing the inductance of the coil and the voltage induced therein, in a vehicle using an inductive-speed-sensor having at least the coil and FEM; recording the inductance-change of the coil, and determining the speed based on the changed-inductance; in which the inductance-change is recorded and the speed is determined based on the changed-inductance only until the determined-speed has reached a speed-limit-value (SLV) starting from lower-speeds, in which a voltage-change induced in the coil is recorded and the speed is determined based on the changed-voltage when the determined-speed has exceeded the SLV starting from lower-speeds, and in which an inductance-change is recorded and the speed is determined based on the changed-inductance when the determined-speed has reached/dropped below the SLV starting from higher-speeds. Also described are a related driver assistance system and vehicle.
