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).
Claims14
A method for monitoring a status of a tyre fitted on a vehicle, the method comprising:
- with the vehicle in motion and the tyre in rotation, acquiring a motion signal representative of a motion of a crown portion of the tyre, wherein the motion signal temporally corresponds to a plurality of turns of the tyre;
- obtaining a frequency spectrum of the motion signal;
- and
- determining the status of the tyre based the frequency spectrum,
- wherein the motion signal is representative of an axial component of the motion of the crown portion;
- and
- wherein the motion signal comprises a plurality of motion signal portions respectively temporally corresponding to a plurality of continuous time intervals, wherein each continuous time interval is temporally separated from the temporally subsequent continuous time interval, and wherein each motion signal portion temporally corresponds to a plurality of turns of the tyre.
A system for monitoring a status of a tyre fitted on a vehicle, the system comprising:
- a motion sensor fixed at a crown portion of the tyre and which detects a motion of the crown portion of the tyre and generates a motion signal representative of the motion;
- at least one processing unit in communication with the motion sensor and programmed to:
- acquire the motion signal, wherein the motion signal temporally corresponds to a plurality of turns of the tyre;
- obtain a frequency spectrum of the motion signal;
- and
- determine the status of the tyre based on the frequency spectrum,
- wherein the motion sensor detects an axial component of the motion of the crown portion and the motion signal is representative of the axial component of the motion;
- and
- wherein the motion signal comprises a plurality of motion signal portions respectively temporally corresponding to a plurality of continuous time intervals, wherein each continuous time interval is temporally separated from the temporally subsequent continuous time interval, and wherein each motion signal portion temporally corresponds to a plurality of turns of the tyre.
