Abstract: An accelerator pedal device includes a slide guide path which is formed in a housing, a first slider which is engaged with the pedal arm for receiving pedaling force as being slidably arranged in the slide guide path and which includes a first inclined face inclined against a movement direction of the first slider, a second slider which is slidably arranged in the slide guide path and which includes a second inclined face contacted to the first inclined face, and an urging spring which exerts urging force in a direction opposing to the pedaling force as being engaged with the second slider, wherein the slide guide path is formed as being tapered in a direction of movement of the first slider and the second slider which are moved in association with depression of the accelerator pedal. Accordingly, desired hysteresis can be obtained on the pedaling force while achieving downsizing.

Abstract: An accelerator pedal apparatus includes an accelerator pedal, a hysteresis generating mechanism which generates hysteresis on pedaling force, a reaction force adding mechanism which adds reaction force to push back the accelerator pedal toward a rest position, and controller which performs drive control of the reaction force adding mechanism, while the controller performs drive control of the reaction force adding mechanism so that reaction force is added during returning as well as during depressing of the accelerator pedal under predetermined conditions as the reaction force being larger than pedaling force difference between pedaling force at the depression side and pedaling force at the return side of the pedaling force hysteresis to obtain an appropriate accelerator feeling and to quickly perform danger avoidance or danger notification.

Abstract: An accelerator pedal apparatus including an actuator pedal, a hysteresis generating mechanism which provides a hysteresis pedaling force characteristic having larger pedaling force in a depression direction than that in a return direction, and a reaction force adding control mechanism which adds operational reaction force to operation of the accelerator pedal based on an adjustment force generation command from an upper unit, while the operational reaction force added by the reaction force adding control mechanism is not larger than a hysteresis amount generated by the hysteresis generating mechanism.
