ABSTRACT:
A system and method for controlling a vehicle sliding door driven by an electric motor. The method includes generating a periodic signal representing a door position, measuring first and second pluralities of signal periods such that errors in the periodic signal are minimized, comparing the first and second pluralities of signal periods, and generating a motor control signal operative to deactivate the motor when the second plurality of signal periods exceed a selected percentage of the first plurality of signal periods. A system for carrying out the method is also disclosed.
