Method for detecting a wheel of a vehicle

摘要

A rotating wheel of a vehicle is detected by evaluating the Doppler shift of a measuring beam emitted by a detector unit passed by the vehicle, reflected by the wheel and returned in Doppler-shifted form. 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. The direction and distance of the onboard unit from the transceiver are measured on the basis of at least one radio communication between the same. The radiation direction or radiation position of the measuring beam is controlled in accordance with the measured direction and distance and taking into consideration the aforementioned relative position and location. The 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.

1. 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, the method comprising:
measuring the direction and distance of the onboard unit from the transceiver on the basis of at least one radio communication between the onboard unit and the transceiver; 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 relative position and location; wherein the 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 consideration.
