Abstract

A method of onboard determination of vehicle wheel alignment is provided. In a first step, a lateral acceleration signal is generated, using an accelerometer mounted on the vehicle wheel. In a second step, a first lateral acceleration value ais derived from a first portion of the lateral acceleration signal, which is during a longitudinal acceleration aof the vehicle. In a third step, a second lateral acceleration value ais derived from a second portion of the lateral acceleration signal, which is measured when the longitudinal acceleration has ceased and the vehicle is travelling at constant speed. In a fourth step, the magnitude of the longitudinal acceleration aassociated with the first portion of the lateral acceleration signal is measured. In a fifth step, a toe angle α of the vehicle wheel is determined according to the following relationship: where g is the gravitational acceleration constant.
