Abstract:
1. A method for determining a cornering angle of a tyre fitted on a vehicle during running of said vehicle on a rolling surface, comprising: determining a lateral acceleration of a portion of said tyre axially extending between a pair of sidewalls of the tyre and which is spaced a distance from an equatorial plane of said tyre; determining a rotation speed of said tyre; and wherein said determining the lateral acceleration comprises acquiring a lateral acceleration signal when said portion of the tyre is outside a contact region between said tyre and said rolling surface, and acquiring a lateral acceleration signal when said portion of the tyre is within said contact region; and wherein said determining the lateral acceleration signal comprises calculating a peak value of said lateral acceleration signal within said contact region; and determining said cornering angle from said lateral acceleration and said rotation speed.
