A method for determining the axis of rotation and of the center of rotation of a vehicle wheel

摘要

The invention relates to a method for determining the axis of rotation and of the center of rotation of a vehicle wheel in position by means of at least two and position of the associated picture-taking units during the travel of the vehicle and a these downstream, the recorded image information processing evaluation device with the inclusion of a plurality of existing or on the wheel is mounted for the measurement wheel features (10) and at least one on the vehicle body, which is present or is mounted for the measurement body feature, wherein time synchronously 2 - d - coordinates of the wheel features (10) and the at least one vehicle body from this feature is detected and whose 3 - d - coordinates are calculated in certain time intervals and in a predetermined reference point or corresponding reference position of the vehicle wheel while taking into account of the relative to the reference position of the at least one vehicle bodywork feature route traveled be back-calculated. To achieve the most error-free measurement results, in particular, also during travel on a real roadway, it is provided that the track curves of the wheel features (10) and the at least one body feature in the evaluation of an analysis with respect to the effects of at least one of the influencing variables steering angle, steering movement, road unevenness, be subjected to change in speed, and that from the analysis of correction values or mechanical function for correcting the effects are obtained ..
