Method of sensing the axle geometry on motor vehicles with independent wheel suspensions
First Claim
1. Method of determining at least one of toe-in, camber and caster on a motor vehicle having a plurality of vehicle wheels mounted on respective independent wheel suspension units, each of which includes a plurality of suspension links which support one of said wheels on a body of said motor vehicle, with measured values being sensed by measuring techniques and sent to a computer, wherein:
- inclination is measured for respective wheel suspension links of at least one of the respective wheel suspension units, independently of a level position of the motor vehicle;
measured inclination values are compared with one of vehicle-type-specific setpoint values and setpoint value ranges, adapted in the computer to the currently applicable motor-vehicle position, or measured inclination values are converted in the computer to a neutral motor-vehicle position and compared with the vehicle-type-specific setpoint values or setpoint value ranges based on a neutral motor-vehicle positions; and
based on deviations between the measured values and corresponding setpoint values or setpoint value ranges determined during comparison, at least one of a measuring or checking record of the axle geometry and a set of machine-processable alignment data is produced.

Abstract
A method of sensing the axle geometry, in particular the toe-in, camber and caster, on motor vehicles with independent wheel suspensions. The inclination of certain links of the wheel suspensions is measured in at least one arbitrary motor-vehicle position, or the inclination measurements are carried out in the case of certain links of the wheel suspensions and one specific location of the vehicle body in at least one arbitrary motor-vehicle position. The measured values sensed are sent via a data line or wirelessly to a computer and either compared with vehicle-type-specific setpoint values or setpoint value ranges adapted in the computer to the currently applicable motor-vehicle position or are converted in the computer to a neutral motor-vehicle position and compared with the vehicle-type-specific setpoint values or setpoint value ranges based on a neutral motor-vehicle position. With the aid of the deviations between the measured values and the corresponding setpoint values or setpoint value ranges determined during comparison, a measuring or checking record of the axle geometry and/or a set of machine-processable alignment data is produced.
