Abstract: A method for locating the longitudinal position, on the front end or rear end of a vehicle with engine, of wheels fitted with an electronic module. Each electronic module incorporates elements for measuring vibrations stressing the corresponding wheel and resulting from rotation of the engine. First, a spectral analysis is performed in a preliminary phase, with the engine running, of signals delivered by the respective measurement elements of wheels mounted on the front end and the rear end, to establish a criterion for differentiating the signals by a frequency offset between these signals. Locating the longitudinal position of the wheels includes carrying out a spectral analysis of the signals delivered by the different measurement elements, with the engine running, and deducing from the frequency offset between the signals an indication of the longitudinal position of each wheel.

Abstract: A method of transmitting signals from electronic housings, each mounted on one wheel of a vehicle, to a central unit (11) on the vehicle, uses spread spectrum. There is allocated, on the one hand, to each electronic housing (6-9) and to the central unit (11), a first common generic orthogonal spread code (Cg) identical for the electronic housings and the central unit and, on the other hand, to each electronic housing, a second orthogonal spread code (Ci) specific to the electronic housing. An initializing procedure causes the transmission by each electronic housing of a spread signal (e) based on the common generic spread code (Cg), incorporating the second specific orthogonal spread code (Ci) and the identification code (ID) of the electronic housing. Subsequent transmissions include transmission by each electronic housing of a spread signal (e) on the basis of the second specific spread code (Ci) of the electronic housing.
