Claim Text:
1. A method for determining characteristics of an axle geometry of a vehicle as part of an axle alignment procedure, the method comprising: steering a wheel mounted on an axle of the vehicle to various steering positions having different steering angles; determining, by a spatial position determining unit, a spatial position of the wheel in the different steering positions; determining, by an evaluation unit including a processor, an axis of rotation of the wheel in the particular steering position from the results of the determination of the spatial position; modeling, by the evaluation unit, a parametric model of the steering axis; determining, by the evaluation unit, the axis of rotation of the wheel from the parametric model of the steering axis for the different steering positions; adapting, by the evaluation unit, the parametric model of the steering axis to the axes of rotation determined from the measurement of the spatial position of the wheel in the different steering positions; and determining, by the evaluation unit, characteristics of the axle geometry from the adapted parametric model of the steering axis, for the axle alignment.
