Patent ID: 8620554

Claim:
An accelerator apparatus comprising: an accelerator device; an accelerator device position sensor that detects an accelerator device position of the accelerator device; and a reaction force controller that adjusts a reaction force of the accelerator device, the reaction force controller being configured to set a first position threshold based on an operating state, set a second position threshold that is equal or less than the first position threshold, increase the reaction force in response to the accelerator device passing the first position threshold, reduce the reaction force at a reaction force decrease rate to return to the base reaction force in response to the accelerator device being reduced to a position below the second position threshold from a position above the first position threshold, and vary the reaction force decrease rate based on a change condition of the accelerator device position indicating a rate at which the accelerator device moves past a reaction force increase cancellation threshold at a time as the accelerator device is reduced to a position below the second position threshold.
