Abstract
An accelerator pedal is urged in an accelerator closing direction by a hysteresis spring and a return spring. A first increase rate is obtained by dividing an urging force of the hysteresis spring exerted in an accelerator-full-opening position of the accelerator pedal by the urging force of the hysteresis spring exerted in an accelerator-full-closing position of the accelerator pedal. A second increase rate is obtained by dividing an urging force of the return spring exerted in the accelerator-full-opening position of the accelerator pedal by the urging force of the return spring exerted in the accelerator-full-closing position of the accelerator pedal. The second increase rate is smaller than the first increase rate.
Claims5
An accelerator apparatus comprising:
- a support member that is installable to a body of a vehicle;
- an accelerator pedal that is rotatably supported by the support member;
- a rotational angle sensing device that senses a rotational angle of the accelerator pedal relative to the support member;
- a resistance force application device that applies a rotational resistance force to the accelerator pedal such that the rotational resistance force is increased when a rotational angle of the accelerator pedal from an accelerator-full-closing position of the accelerator pedal is increased;
- a first urging device that urges the accelerator pedal in an accelerator closing direction through the resistance force application device;
- and
- a second urging device that urges the accelerator pedal in the accelerator closing direction without using the resistance force application device, wherein:
- a first ratio is defined as a value that is obtained by dividing an urging force of the first urging device at an accelerator-full-opening time by an urging force of the first urging device at an accelerator-full-closing time;
- a second ratio is defined as a value that is obtained by dividing an urging force of the second urging device at the accelerator-full-opening time by an urging force of the second urging device at the accelerator-full-closing time;
- and
- the second ratio is smaller than the first ratio.
