Abstract
Measurement devices are mounted on left and right steerable wheels of a vehicle. Caster is calculated for each of the wheels based upon measurements made with the measurement devices. Pitch at zero toe is determined for the left and right wheels and a steering axis inclination (SAI) compensation term is determined. Live caster is calculated using the live pitch of the wheel, the caster calculated for the wheel, the pitch at zero toe for the wheel and the SAI compensation term. An output representative of the live caster is provided.
