METHOD FOR CALIBRATING AND/OR ADJUSTING THE INTRINSIC COORDINATE SYSTEM OF A VEHICLE ASSEMBLY RELATIVE TO A COORDINATE SYSTEM OF THE VEHICLE AND VEHICLE TEST BENCH FOR IMPLEMENTING THE METHOD
The present invention relates to a method, in which the position and orientation of a test bench assembly (1) is determined in a current position. The test bench assembly (1) interacts with the vehicle assembly in the vehicle test bench. In order to be able to calibrate the vehicle assembly, the position and orientation of the test bench assembly (1) must be known. The position of the test bench assembly (1) in the vehicle test bench can be altered. This can result in a torque occurring when the test bench assembly (1) is offset to the side, which leads to an inclination of the support (2) of the test bench assembly (1). This inclination of the support (2) should be taken into account and, if necessary, compensated for, when determining the position and orientation of the test bench assembly (1). The invention also relates to a vehicle test bench for carrying out such a method.

A method is for determining the axle geometry of a vehicle, wherein light of a given structure is projected onto a vehicle wheel, and the diffusely reflected light can be analyzed in order to determine the orientation of the plane of the vehicle wheel. Several lines of a laser light generated by means of one or several laser light sources are projected on the wheel, and one or several of these lines fades in and/or out in temporal succession. The reflected light is captured by means of one or several cameras.

METHOD AND DEVICE FOR ADJUSTING THE STEERING WHEEL OF A MOTOR VEHICLE
The invention relates to a method and a device for adjusting the steering wheel of a motor vehicle. The aim of the invention is to enable an automatic adjustment of the steering wheel in the steering clearance centre by 'stabilising' or carrying out a steering hysteresis measurement, and the subsequent adjustment of the steering wheel, in a simple, rapid and cost-effective manner. To this end, the invention relates to a method for adjusting the steering wheel of a motor vehicle in the steering wheel clearance centre, said method being characterised by the following steps: the floating plates of the vehicle geometry test bed, on which the front wheels of the motor vehicle are arranged, are rotated when the wheels are stopped in order to cause the rotation of steering wheel; the steering wheel angle is determined according to the triggered steering wheel movement; and the steering wheel clearance centre is adjusted. The invention shows that reproducible rotations of the steering wheel can be triggered by the floating plates of the vehicle geometry test bed, enabling an automatic adjustment of the steering wheel in the steering wheel clearance centre to be carried out rapidly and easily.
