Abstract
Apparatus and method for determining the alignment positions and orientations of vehicle wheels includes a pair of measurement transducers, each of which is mounted on separate vehicle wheels and each of which is capable of measuring the range and relative bearing to the other. Three such pairs of measurement transducers are mounted on the vehicle wheels in conventional locations. A computer is connected to the transducers and programmed to compute the toe alignment measurements in a conventional manner. The computer is further programmed to compute the coordinates of the wheels, in an arbitrary coordinate system, from the relative range and bearing measurements. The coordinate system may be transformed relative to the sensor center line, the vehicle thrust line, the vehicle frame or body center line, or any desirable reference frame, thereby providing measurements of the actual wheel positions and alignment angles in that transformed coordinate system. To facilitate determining a coordinate system relative to the body or frame, additional transducers may be used to determine the location of the body relative to the sensors.
