The document describes an ACPE system for judging pedal misapplication from driver accelerator pedal operation and vehicle motion without object detection sensors, and suppresses sudden acceleration. The system performs pedal error checks to determine whether sudden accelerator operation may be pedal misapplication, non-operation checks to verify whether the scene involves intended acceleration, and suppresses acceleration if steps determine pedal error. The system does not activate during intended acceleration in hard-to-distinguish scenes including turning, changing lanes, starting at stop signs or signal lights, and steep uphill driving. False positive activation depends on driver maneuver; measures applied in Japan include offering the system as an option, restricting access to dedicated key users only, and explaining possible false positive activation at point of sale.
