METHOD FOR DETECTING VEHICLE WHEEL Russian patent published in 2017 - IPC G01N21/84 

FIELD: transportation.

SUBSTANCE: invention relates to a method for detecting a rotating wheel (1) of a vehicle (2) by estimating the Doppler frequency shift of the measurement beam (6) emitted by the detector unit (5) by which the vehicle (2) passes, reflected by the wheel (1) and returned with a Doppler shift. In the position (R) relative to the wheel (1), the vehicle (2) comprises an on-board device (15) capable of establishing radio communication (23) with a transceiver (24) installed in a known position (L) in the detector unit; the method comprising: measuring the direction (δ) and the distance (z) to the on-board device (15) from the transceiver (24) by means of at least one radio communication (23) between said devices; and the control of the radiation direction (α, β, γ) or the position (A) of the measuring beam (6) radiation in accordance with the measured direction (δ) and distance (z) and taking into account the aforementioned relative position (R) and known position (L).

EFFECT: increasing the reliability of detecting the rotating wheel of the vehicle.
