METHOD FOR ADJUSTMENT OF VEHICLE WHEEL ALIGNMENT ANGLE Russian patent published in 2009 - IPC G01M17/00 G01B11/26 

FIELD: instrument making.

SUBSTANCE: invention is related to procedure of measurement and adjustment of vehicle wheels camber and toe. Method consists in the fact that optical target is made in the form of circular cylinder, an accidental image is applied on it. For each position of vehicle wheel they read images with the help of television chamber. Using computer, they calculate functions of mutual correlation of memorised video signals of extreme reading lines and extreme reading lines relative to central line, their extremes are defined, positions of which are used to identify appropriate shifts of optical target images. Shift of extreme reading lines images is identified. Ratio of extreme reading lines images shift to distance between extreme reading lines of television camera is identified, and its value is taken, when required, as wheel camber. Coefficient of television camera lens zoom is increased until this value of wheel camber is permanent to appropriate maximum value of television camera lens zoom coefficient. Shifts of extreme reading lines images are identified relative to central line, and camber is determined, steering wheel is installed in initial position, and wheel camber is adjusted.

EFFECT: simplified process of obtainment and application of information about shifts of optical target images.
