METHOD FOR DETECTING VEHICLE WHEEL Russian patent published in 2017 - IPC G01S7/41 G01S13/91 G01S13/58 G08G1/01 

FIELD: transportation.

SUBSTANCE: method for detecting a rotating wheel (1) of a vehicle (2) is proposed, characterized in that the wheel (1) is detected by estimating the Doppler shift of the frequency of the measuring beam (6) reflected by the wheel (1) and returned with the Doppler shift, emitted by the detector unit (5), past which said vehicle (2) passes. In the relative position (R) relative to the wheel (1), the vehicle (2) comprises an onboard device (15) capable of establishing the radio communication (23) with a transceiver (24) installed in a known position (L) in the detector unit. The method includes: measuring the direction (δ) and the distance (z) to the onboard device (15) from the transceiver (24) via the radio communication (23) between said devices and control of the radiation direction (δ, β, γ) or the radiation position (A) of the measuring beam (6) in accordance with the measured direction (δ) and the distance (z), and taking into account the aforementioned relative position (R) and the position (L). The relative position (R) is saved in the onboard device (15) and read from the onboard device (15) by means of the radio communication (23) for accounting at the above control.

EFFECT: creating an improved method for detecting wheels, based on Doppler measurements.
