A method and a device to adjust the axle geometry of a vehicle ( 1 ), wherein measurement values are taken into account, which are automatically detected at the wheels that are arranged at a fully assembled chassis ( 14 ) of the vehicle ( 1 ). Advantageously, the chassis ( 14 ) is moved to an empty-weight position and at least one of the wheels is rotated. Preferably, an additional measurement value, which represents an inclination of the steering wheel ( 18 ) of the vehicle ( 1 ) is detected and taken into account. Advantageously, the adjusting device for adjusting the axle geometry is integrated into an assembly line after assembly devices that serve to at least assemble the chassis ( 14 ) and the wheels of the vehicle ( 1 ).

1. A method, comprising:suspending a vehicle;while the vehicle is suspended, applying an external counter-force to a chassis of the vehicle; andwhile the vehicle is suspended, measuring a wheel alignment parameter for a wheel of the vehicle. 2. The method according to claim 1, further comprising:rotating the wheel during said measuring. 3. The method according to claim 2, wherein the wheel is rotated during said measuring for at least one full rotation of the wheel; and further comprising averaging results of said measuring over the full rotation. 4. The method according to claim 2, wherein said measuring comprises:identifying at least one point of the wheel as a reference point;determining a plane of rotation of the wheel; anddetermining a rotational axis of the wheel. 5. The method according to claim 4, further comprising:calculating further axle geometry parameters. 6. The method according to claim 1, further comprising:automatedly adjusting an axle geometry parameter based on the measured wheel alignment parameter. 7. The method according to claim 1, further comprising:measuring an inclination parameter for a steering wheel of the vehicle. 8. The method according to claim 7, further comprising:automatedly adjusting an axle geometry parameter based on the measured wheel alignment parameter and the measured inclination parameter. 9. An apparatus, comprising:a frame configured to suspend a vehicle;a device configured to apply a force to at least one wheel mounted to a chassis of the vehicle while the vehicle is suspended by said frame, the force being sufficient to spring-compress the chassis of the vehicle to a compressed position; anda metrology system arranged to measure an alignment value for the wheel of the vehicle while the vehicle is suspended by said frame. 10. The apparatus according to claim 9, wherein said metrology system comprises:a light source arranged to project light onto the wheel;a light detector arranged to receive light backscattered from the wheel; anda processor configured to calculate positional data for the wheel from the received light. 11. The apparatus according to claim 10, wherein said light source comprises a laser, and wherein said light detector comprises a video camera. 12. A method, comprising:in a vehicle production line, following a chassis assembly stage for a vehicle, bringing the vehicle, while suspended, in an empty-weight position;while the vehicle is in the empty-weight position, measuring an alignment parameter for a wheel of the vehicle;utilizing the alignment parameter to adjust an axle geometry for the vehicle; and removing the vehicle from the production line. 13. The method according to claim 1, wherein said measuring of the wheel alignment parameter is performed during said applying of the external counter-force. 14. The method according to claim 1, wherein the external counter-force causes the chassis of the vehicle to reach a construction position. 15. The method according to claim 1, further comprising:allowing the chassis of the vehicle to spring-deflect to a position for measurement. 16. The method according to claim 15, wherein the position for measurement is at least approximately an empty-weight position of the chassis of the vehicle. 17. The method according to claim 1, wherein the external counter-force is applied to the chassis of the vehicle via wheels mounted to the chassis. 18. The method according to claim 12, further comprising, following the chassis assembly stage and prior to bringing the vehicle in the empty-weight position, applying a force to the wheel that spring-deflects the chassis of the vehicle.
