    • The invention relates to a method for determining the rotational axis and the rotating center of a vehicle wheel by means of at least two image capture units assigned to each other in position and situation during the journey of the vehicle, and by means of an analysis unit arranged downstream of said units, processing the recorded image information, taking into account multiple wheel features (10) present on the wheel or attached for the measurement, and by means of at least one bodywork feature present on the bodywork or attached for the measurement, wherein 2D-coordinates of the wheel features (10) and of the at least one bodywork feature are synchronously detected, and from these the 3D-coordinates of the features are calculated at certain time intervals and counted back to a previously established reference time point or corresponding reference position of the vehicle wheel, taking into account the distance traveled by the at least one bodywork feature relative to the reference position. To achieve measurement results that are as error free as possible, especially also when traveling on a real driving surface, it is provided that the paths of the wheel features (10) and of the at least one bodywork feature in the evaluation undergo an analysis with respect to the effects of at least one of the influencing variables, steering lock angle, steering motion, driving surface unevenness, and change of speed, and that from the analysis, correction factors or compensation functions are obtained for correcting the effects.

    • A method for compensating axial misalignment between wheel-mounted alignment sensors and an axis of rotation for an associated wheel. The method compensates sensors mounted to each wheel of a vehicle simultaneously, without requiring jacking of the vehicle wheels above a supporting surface, and which only requires wheel rotational movement over an arc of 60 degrees or less. The method utilizes measurements of a change in a wheel toe angle and measurements of a change in a wheel camber angle, during a measured rotational movement of the wheel, to identify sinusoidal variation in the respective toe and camber angles during the wheel's rotational movement, from which a measure of axial misalignment between the wheel-mounted alignment sensor axis of rotation and the wheel axis of rotation is identified.

    • A vehicle alignment sensor system includes a first sensor assembly for measuring at least a first angle with respect to a fixed reference, that angle being related in a predetermined manner to an alignment angle of a vehicle whose alignment is to be measured, and a second sensor assembly for mounting in a known geometrical relationship to a wheel of a vehicle whose alignment is to be measured. The first sensor assembly has at least one detector, and the second sensor assembly has at least a pair of emitters in fixed geometrical relationship with respect to each other. The detector is capable of measuring the apparent geometrical relationship of the pair of emitters to determine a relative alignment angle of the vehicle, so that a true alignment angle of the vehicle is determinable from the first angle and the relative alignment angle. A calibration method using the present invention is also disclosed.

    • An apparatus and method for determining the orientation parameters of a wheel-alignment optical target 10 affixed to a vehicle wheel 20 by a no-compensation wheel clamp 16. The wheel-alignment optical target includes a stub shaft 24 adapted for insertion within an axial bore 18 of the no-compensation wheel clamp after the wheel clamp is secured to the vehicle wheel. An optical imaging system observes the optical target and measures the orientation of the target face in a first position. The optical target is rotated partially about the longitudinal axis of the stub shaft, and the optical target is again observed and the orientation of the target face is again measured by the optical imaging system. By comparing the measured orientations of the optical target at the two rotational positions, a compensation vector Vc describing the alignment of the target face relative to the stub shaft is be determined and stored for subsequent uses of the optical target.
