Method for locating the position of the wheels of a vehicle, each equipped with an electronic module for measuring operational parameters of each wheel, includes: controlling the transmission, by the module equipping that wheel, of n signals transmitted at times tto tfor given angular positions θto θof the module, to a connected central processing unit, and to speed sensors each positioned close to a wheel, capable of delivering, values convertible into angular values, data representing the orientation of the wheel. The central processing unit is programmed to calculate, for each series of angular values δto δprovided by a wheel measuring sensor at the times tto t, a characteristic value V1-Vr representing the dispersion of the values δ, (δ-θ) . . . (δ-θ), and to compare the characteristic values to allocate, to the electronic module, the position of the wheel located close to the wheel speed sensor. 2. The locating method as claimed in claim 1 , characterized in that the speed of movement Vof the vehicle (V) is measured and in that a threshold speed Vis determined beyond which an inhibit procedure is used: {'sub': v', 's', 'n', 'n', 'n', '1', '2', '2', 'n', 'n, 'consisting, when the speed of movement Vof the vehicle (V) becomes less than the threshold speed Vin storing the characteristic values V1, V2 . . .
