Abstract
The present disclosed subject matter relates to a device and a method for detecting an axle of a vehicle travelling on a road. The device includes a plurality of radar sensors, which each, by means of an approximately vertically downwardly directed measuring beam of the transceiver thereof, at successive moments in time generate a Doppler speed measurement value for an object reflecting the measuring beam, and an evaluation unit, which is connected to measurement value outputs of the radar sensors and which is configured to detect an axle when two radar sensors, within a tolerance time window, generate maxima or minima of the speed measurement values thereof, said maxima or minima being of substantially identical size.
