Device and method for processing a signal received inside a vehicle and originating from one of its wheels, and corresponding learning process

Detection and emission modules (3) respectively installed on several wheels (2) of the vehicle (1) are capable of emitting a signal including an indication of a state of the wheel. The captured signal is compared to several waveforms respectively stored in relation to wheel positions, to select a wheel position for which the stored waveform matches the captured signal. After preprocessing the captured signal and identifying extrema of the preprocessed signal, the comparison between the captured signal and a waveform includes applying a temporal transformation to the preprocessed signal to align first and second extrema of the preprocessed signal with first and second extrema of said waveform, and calculating a distance between the transformed signal and said waveform. The selected wheel position is that for which the calculated distance is minimal.
