Abstract
An improved method and system are provided for performing rolling runout compensation for vehicle wheel alignment. A plurality of sets of camber and toe measurements are acquired for a pair of vehicle wheels, each at a different, relatively small rollback angle between measurements; e.g., rolling the vehicle more than 0° and less than 180° from the last wheel position. Best fit sine waves are computed for each of the camber and toe measurements using the acquired data, and the best fit parameters are applied to compute runout at the current wheel angle. The computed runouts are subtracted from the measured camber and toe values to get true camber and toe values of the pair of wheels.
