Abstract
A method for localization the position of wheels of a vehicle includes: storing, for each wheel, an image of the intensity of the signal originating from an electronic module fitted to the wheel; controlling the emission by each electronic module of a sequence of n signals emitted with predetermined time intervals; computing for each sequence of n signals, the temporal variation of the correlation coefficients between each signal of the sequence and each of the stored images; computing the peak of correlation of the correlation coefficients of each of the n signals and the temporal position over a wheel revolution of each of the n peaks of correlation; and selecting, for each stored image, the wheel at the origin of the emission of sequences having the highest peaks of correlation associated with time intervals corresponding to the time intervals of emission of the n signals of the sequences.
