Method and apparatus for vehicle wheel alignment testing

摘要

Method and apparatus for non-contact evaluation of wheel alignment for vehicles utilizes laser-based range-finders mounted at locations between which the vehicle is driven for test purposes. Range-finding at three locations on the wheel enables wheel attitude to be determined. Locations are chosen so that range-finding is carried out where a significant contour in the wheel assembly occurs, thereby enabling a clear and characteristic signal to be obtained from relatively simple apparatus.
