A wheel alignment system uses head units attached to each of the four wheels of an automotive vehicle. Angle measurements are taken using light sources and light sensors. Pitch sensors measure the pitch of the head units with respect to a horizontal plane. The head units are connected to the left and right front wheels of the automotive vehicle. The pitch information is used to compensate for errors in left and right cross-toe measurements between the left and right front wheels of the automotive vehicle.
A system for measuring the angular relationship of wheels of a vehicle comprising: a first head unit for mounting to a first wheel of the vehicle, comprising: a first wheel for mounting to the first wheel; a first arm having a distal end, a proximal end, and a length, the proximal end connected to the first wheel mount, the first arm extending in a horizontal plane generally perpendicular to an axis of rotation of the first wheel; a first angle sensor connected to the first arm at the distal end of the first arm for sensing an angular relationship; a fir...
