Abstract: Method (200), and related system (100), for monitoring a status of a tyre (99) fitted on a vehicle, the method comprising: -with the vehicle in motion and the tyre (99) in rotation, acquiring (3, 6) a motion signal representative of a motion of a crown portion (31) of the tyre (99), wherein the motion signal temporally corresponds to a plurality of turns of the tyre (99); -filtering (15, 42) from the motion signal a part of the motion signal temporally corresponding at least to each passage of the crown portion (31) in a footprint area of the tyre (99), for obtaining a filtered motion signal; -obtaining (4, 7) a frequency spectrum of the filtered motion signal; -determining (11) the status of the tyre (99) based on the frequency spectrum.

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.
