Patent ID: 8316700

Claim:
A method for determining at least one operating parameter of a tyre fitted on a vehicle, comprising: providing an oscillating structure comprising a housing and a piezoelectric element coupled to said housing and capable of oscillating in an oscillation direction; coupling said oscillating structure to a crown portion of said tyre; rotating said tyre on a rolling surface so as to cause oscillation of said oscillating structure, thereby causing said piezoelectric element to generate an electrical signal; and processing said electrical signal so as to determine said at least one operating parameter of the tyre, wherein said processing of said electrical signal comprises: determining whether a rotation speed of said tyre is greater than a threshold speed; and in the negative, extracting information for determining said at least one operating parameter of the tyre from a low-pass filtered signal, the low-pass filtered signal being obtained by removing at least frequency components of said electrical signal having a frequency higher than or equal to a resonance peak frequency of said oscillating structure.
