Abstract: Method for Detecting a Wheel of a Vehicle The invention relates to a method for detecting a rotating wheel of a vehicle by evaluating the Doppler shift of a measuring beam, which is emitted by a detector unit passed by the vehicle, reflected by the wheel and returned in Doppler-shifted form, wherein, in a relative position to the wheel, the vehicle comprises an onboard unit, which can establish a radio communication with a transceiver having a known location in the detector unit, comprising: measuring the direction and distance of the onboard unit from the transceiver on the basis of at least one radio communication between the same; and controlling the radiation direction or radiation position of the measuring beam in accordance with the measured direction and distance and taking into consideration the aforementioned relative position and location; wherein this relative position is stored in the onboard unit and is read from the onboard unit by way of a radio communication for the purpose of the aforementioned consideration.
