Abstract
A method for determining characteristics of an axle geometry of a vehicle including the following: steering a wheel mounted on an axle of the vehicle to various steering positions having different steering angles; determining the spatial position of the wheel at the different steering positions; determining the particular axis of rotation of the wheel in the different steering positions from the results of the determination of the spatial position; modeling a parametric model of the steering axis; adapting the parametric model of the steering axis to the axes of rotation of the wheel determined from the measurement of the spatial position; and determining characteristics of the axle geometry from the adapted parametric model of the steering axis.
