Abstract
Method (), and related system (), for monitoring a status of a tyre () fitted on a vehicle, the method () comprising: —in a first operative phase with the tyre () in a reference status: —during an advancement of the vehicle, acquiring () at least one first signal representative of a motion of a crown portion () of the tyre (); —obtaining () a first frequency spectrum of the at least one first signal, the first frequency spectrum comprising a first plurality of peaks; —identifying () a first determined peak in the first plurality of peaks and determining a first frequency of the first determined peak; —in a second operative phase subsequent to the first operative phase: —during an advancement of said vehicle, acquiring () a second signal representative of the motion of the crown portion (); —obtaining () a second frequency spectrum of the second signal, the second frequency spectrum comprising a second plurality of peaks; —identifying () a second determined peak in the second plurality of peaks corresponding to the first determined peak in the first plurality of peaks, and determining () a second frequency of the second determined peak; —determining () a reference frequency as a function of the first frequency of the first determined peak; —determining () a current frequency as a function of the second frequency of the second determined peak; —monitoring () the status of the tyre () based on a comparison between the current frequency and the reference frequency, or between two values of a same physical quantity, the two values being correlated to the current frequency and to the reference frequency respectively, wherein the physical quantity is a mass or a moment of inertia or a stiffness of the tyre ().
