ABSTRACT:
An accelerator pedal control mechanism provides a positionable stop to resist pedal depression beyond a point at which optimum fuel economy is realized during vehicle acceleration. The position of the stop relative to the accelerator pedal is controlled by an electronic circuit that is programmed to select the desired point of accelerator depression for a given condition of engine operating parameters. A caged limit spring is carried on the underside of the accelerator pedal for engagement with the stop, thus allowing the operator to sense the additional resistance of the spring through the accelerator pedal when the appropriate amount of accelerator depression is reached. The spring allows the operator to override the programmed control by pressing on the accelerator pedal with sufficient force to overcome the limit spring.
