摘要： The present invention concerns a method of on board determination of vehicle wheel alignment. In a first step (21) of the method, a lateral acceleration signal is generated, using an accelerometer mounted on the vehicle wheel. In a second step (22), a first lateral acceleration value a
y Acc is derived from a first portion of the lateral acceleration signal, which is during a longitudinal acceleration a
0 of the vehicle. In a third step, (23) of a second lateral acceleration value a
y CS is 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 (24), the magnitude of the longitudinal acceleration a
0 associated with the first portion of the lateral acceleration signal is measured. In a fifth step (25), a toe angle α of the vehicle wheel is determined according to the following relationship: where g is the gravitational acceleration constant.
