摘要
Detection and transmission modules respectively fitted on several wheels of the vehicle are set up to transmit a detection signal incorporating an indication of a state of the wheel. The sensed signal is compared with several waveforms, respectively stored in relation to wheel positions, in order to select a wheel position for which the stored waveform matches the sensed signal. After pre-processing the sensed signal and identifying extrema of the pre-processed signal, the comparison between the sensed signal and a waveform comprises applying a time transform to the pre-processed signal to align first and second extrema of the pre-processed signal with first and second extrema of said waveform and computing a distance between the transformed signal and said waveform. The wheel position selected is the one for which the computed distance is minimum.
