Abstract: Method (200), and related system (100), for monitoring a status of a tyre (99) fitted on a vehicle, the method (200) comprising: —in a first operative phase with the tyre (99) in a reference status: —during an advancement of the vehicle, acquiring (3) at least one first signal representative of a motion of a crown portion (31) of the tyre (99); —obtaining (4) a first frequency spectrum of the at least one first signal, the first frequency spectrum comprising a first plurality of peaks; —identifying (5) 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 (6) a second signal representative of the motion of the crown portion (31); —obtaining (7) a second frequency spectrum of the second signal, the second frequency spectrum comprising a second plurality of peaks; —identifying (8) a second determined peak in the second plurality

Abstract: Method (200), and related system (100), for monitoring a status of a tyre (99) fitted on a vehicle, the method (200) comprising: —with said vehicle in motion and said tyre in rotation, acquiring (3) a motion signal representative of a motion of a crown portion (31) of the tyre (99), the motion signal temporally corresponding to a plurality of turns of the tyre (99); —obtaining (4) a frequency spectrum of the motion signal; —determining (11) the status of the tyre (99) based the frequency spectrum, wherein the motion signal is representative of an axial component of the motion of the crown portion (31).
