Abstract

The following features may be carried out: providing a wheel suspension alignment system having four measuring heads situated in a known position with respect to one another; recording a wheel or a measuring target mounted on it in an initial position of the vehicle; shifting the vehicle from the initial position to at least one further position; recording a wheel, or a measuring target mounted on it, of the vehicle standing in the further position; recording a reference target in at least one of the initial position and the further position of the vehicle, and determining from this an absolute scale; carrying out local 3D reconstructions for determining the translation vectors, the rotation vectors and the wheel rotational angles as well as the wheel rotational centers and the wheel rotational axes of the wheels; and determining the wheel suspension alignment parameters of the vehicle.
