Zusammenfassung
(EN)

The present invention relates to a method for determining parameters of the chassis geometry of wheels of a non steered axle, amuse of the method, a test bench for a vehicle, and a measuring unit. The method relates to determining the parameters of the chassis geometry of the Wheels of the rear axle of a vehicle from measurements of the toe angle in two measuring positions of the vehicle in the test bench, which positions are mutually offset in the x-direction. Wheel runout compensation is achieved thereby. The geometric driving axle thus determined can be used for setting driver assistance systems and for setting the parameters of the chassis geometry of the steered wheels of the front axle. A measuring unit can be designed such that a plurality of parallel lines for generating a planar pattern are generated by means of a parallel displacement of a sensor in the x-direction, which sensor emits linear light having one line. A linear sensor of this kind can in turn be replaced by a sensor comprising a point light source by means of which a line is scanned.
