Abstract
A method for the chassis measurement of a motor vehicle by a chassis measuring device, measuring in a contactless manner, having two measuring devices situated opposite to each other, includes the steps of positioning a first vehicle axle between the two measuring devices; the contactless measuring of the two wheel rims of the first vehicle axle by the two measuring devices; the positioning of a second vehicle axle between the two measuring devices; the contactless measuring of the two wheel rims of the second vehicle axle by the two measuring devices; and ascertaining the wheel position values of all the measured wheel rims by the chassis measuring device.

A method for chassis measurement of a motor vehicle by a chassis measuring device that measures in a contactless manner, having two measuring devices arranged opposite to each other on a measuring station, comprising:
- a) positioning a first vehicle axle between the two measuring devices so that the motor vehicle stands on the measuring station in such a way that wheel rims of its first axle are positioned optimally with respect to the measuring devices;
- b) contactless measuring of two wheel rims of the first vehicle axle by the two measuring devices;
- c) positioning a second vehicle axle between the two measuring devices so that the motor vehicle stands on the measuring station in such a way that wheel rims of its second axle are positioned optimally with respect to the measuring devices;
- d) contactless measuring of two wheel rims of the second vehicle axle by the two measuring devices;
- and
- e) ascertaining wheel position values of all measured wheel rims by the chassis measuring device,
- wherein no targets are applied to the wheel.
A chassis measuring device for motor vehicles, comprising:
- two measuring devices positionable opposite to each other on a measuring station such that the two measuring devices are respectively allocated to one wheel rim of a same axle of a motor vehicle and that by one measuring device respectively one wheel rim is measureable, relative positions of the measuring devices with respect to each other being determined during performance of measurements, wherein the motor vehicle stands on the measuring station in such a way that wheel rims of its first axle are positioned optimally with respect to the measuring devices for a first measurement of its first axle, and the motor vehicle stands on the measuring station in such a way that wheel rims of its second axle are positioned optimally with respect to the measuring devices for a second measurement of its second axle;
- a data processing unit adapted to recalculate measuring results of successive measurements of wheel rims of at least two vehicle axes of the motor vehicle, while taking into account the relative positions of the measuring devices with respect to each other, into wheel position values;
- and
- an output unit adapted to output the wheel position values,
- wherein no targets are applied to the wheel.
A motor vehicle test line, comprising:
- a chassis measuring device for motor vehicles, including:
- two measuring devices positionable opposite to each other on a measuring station such that the two measuring devices are respectively allocated to one wheel rim of a same axle of a motor vehicle and that by one measuring device respectively one wheel rim is measureable, relative positions of the measuring devices with respect to each other being determined during performance of measurements;
- a data processing unit adapted to recalculate measuring results of successive measurements of wheel rims of at least two vehicle axes of the motor vehicle, while taking into account the relative positions of the measuring devices with respect to each other, into wheel position values;
- and
- an output unit adapted to output the wheel position values,
- wherein no targets are applied to the wheel.
