Abstract
A method whereby a central unit carried on board a motor vehicle can identify the wheels of a motor vehicle, by locating a radiofrequency black spot for transmissions between a wheel unit with which a wheel of a motor vehicle is equipped and a wheel-monitoring central control unit carried on board the vehicle, a wheel angle encoding independent of the transmission being in any case performed in order to measure the true rotation of the wheel at a given instant. A string of successive frames providing full angular coverage of the wheel is transmitted from the wheel unit, a receive rate for the frames being established and analyzed in order to detect at least one spot of poorer reception corresponding to the at least one black spot, the angle encoding providing an angle of rotation of the wheel at the instant of detection of the at least one black spot.
