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 ay Acc is derived from a first portion of the lateral acceleration signal, which is during a longitudinal acceleration a0 of the vehicle. In a third step, a second lateral acceleration value ay 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, the magnitude of the longitudinal acceleration a0 associated 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: α = arcsin ( a Y Acc - a Y CS - a 0 ⁢ cos ⁡ ( arcsin ⁡ ( a Y CS g ) ) ) · 180 π where g is the gravitational acceleration constant.
