Method and system for determining operating parameters of a tyre during running of a vehicle

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.
