Abstract: A method for locating at least one wheel of a vehicle, the wheels each being equipped with an electronic device which sends a wheel rotation signal to a central unit, a speed sensor for each wheel which supplies a signal to the central unit. For each electronic device, at least two sequences of several acquisitions are performed by formation of the signal with simultaneous acquisition by the central unit of the signal transmitted by each speed sensor. A pairing is performed of the two signals for an electronic device with each of the wheel speed signals. For each pair, a phase offset is measured between the two signals. When a constant phase offset is measured in the pairs with a speed sensor, the electronic device associated with the signal is identified as being assigned to the wheel associated with the speed sensor.
