摘要： An oscillating structure is coupled to a crown portion of a tyre. The oscillating structure includes a housing and a piezoelectric element coupled to the housing. The piezoelectric element is able to oscillate in an oscillation direction, which could match either a longitudinal or a radial direction of the tyre. An electrical signal generated by the piezoelectric element is processed so as to determine at least one operating parameter of the tyre. The processing includes determining whether a rotation speed of the tyre is greater than a threshold speed; and, in the negative, extracting information for determining the at least one operating parameter of the tyre from a low-pass filtered signal. Such low-pass filtered signal is obtained by removing at least frequency components of the electrical signal having a frequency higher than or equal to a resonance peak frequency of the oscillating structure.
