Method and System for Determining a Cornering Angle of a Tyre During the Running of a Vehicle

摘要

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