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).

Abstract: A method and system for estimating an unevenness parameter of a road segment having a length (L) are disclosed; the method and system take into account road unevenness induced vehicle body motions and are based on the estimation of the deformation, over multiple tire rotations, of at least two tires fitted to different axles of a vehicle.

Abstract: A method and system are disclosed for estimating a relative motion of vehicle body portions with respect to each other along a road segment having a length (L); the method and system allow to estimate road unevenness induced vehicle body motions and are based on the estimation of the deformation, over multiple tire rotations, of at least two tires of a vehicle.
