摘要： Disclosed is a method and a system for determining a cornering angle of a tyre fitted on a vehicle during a running of said vehicle on a rolling surface. The method comprises the steps of: determining the lateral acceleration of a portion of the tyre tread spaced apart from the equatorial plane of said tyre; determining a rotation speed of said tyre; and determining said cornering angle from said lateral acceleration and said radial speed, by using characteristic curves of lateral acceleration amplitude versus predetermined values of cornering angle for at least one rotation speed.

摘要： A method for determining a load exerted on a tyre fitted on a vehicle during a running of said vehicle comprises the following steps: acquiring a first signal comprising a first portion representative of a radial deformation to which a first tread area portion of said tyre is subjected during passage of said first tread area portion in a contact region between said tyre and a rolling surface; measuring an amplitude of said radial deformation in said first signal portion; estimating a rotation speed and an inflation pressure of said tyre in correspondence of said radial deformation; deriving said tyre load from said amplitude, said rotation speed and said inflation pressure.
