초록

An apparatus and method for monitoring and automatically calibrating the primary sensors of a vehicle wheel aligner comprises secondary sensors for signaling the control means of the wheel aligner when the wheels are in known angular orientations. The outputs from the primary angle determining sensors of the wheel aligner are recorded when the secondary sensors signal the control means, and the control means calculates a calibration relationship between the outputs and the known angles to apply to future outputs of the primary sensors.

청구항

In combination with a vehicle wheel aligner having at least one primary sensor mountable to a wheel of a vehicle for measuring the angular orientation of the wheel with respect to a reference, the improvement comprising: first sensor means mountable to the wheel for generating a signal when the wheel is oriented at a first known angle with respect to the reference; and means responsive to the signal generated by the first sensor means for determining a difference between the angle measured by the primary sensor when the wheel is oriented at the first kno...
