ABSTRACT:
A gasoline engine power assisted pedal operated vehicle. The amount of assist provided by the engine is varied in response to variations in the manual force applied by the operator to the pedal mechanism. However, in order to provide smoother power assist, rapid changes in manual power application and, specifically, rapid reductions are dampened in the engine response. In addition, the system includes a disabling device for disabling the connection between the engine and the vehicle propulsion system if the vehicle brakes are actuated.
