Title
(EN) ACCELERATOR PEDALLING FORCE CONTROL DEVICE

Abstract
(EN)

PROBLEM TO BE SOLVED: To eliminate giving of incompatible sense by rattling of an accelerator pedal to a driver.

SOLUTION: When an accelerator opening APS becomes larger than an accelerator opening threshold value APSa and step force of the accelerator pedal 2 is increased relative to base step by a predetermined amount A, the step force is not steppingly increased but an increase ratio of the step force according to the accelerator opening is varied while continuously dividing it to two stages to increase the step force of the accelerator pedal 2. Further, it is set such that the increase ratio of the second step force becomes relatively larger than the increase ratio of the first-time step force. Thereby, when the step force of the accelerator pedal 2 is increased relative to the base step force, rebounding of a foot by rapid increase of the step force can be suppressed and deterioration of operability can be suppressed.

【課題】アクセルペダルのばたつきによる違和感を運転者に与えない。
【解決手段】アクセル開度APSがアクセル開度閾値APSaよりも大きくなりアクセルペダル2の踏力をベース踏力に対して所定量A増加させる際に、ステップ的に踏力を増加させるのではなく、アクセル開度に応じた踏力の増加割合を連続的に2段階に分けて変化させてアクセルペダル2の踏力を増加させている。そして、初回の踏力の増加割合に比べ2回目の踏力の増加割合が相対的に大きくなるよう設定されている。これによって、アクセルペダル2の踏力をベース踏力よりも増加させる際に、急激な踏力の増加により足が跳ね返されてしまうことを抑制することができ、操作性が悪化してしまうことを抑制することができる。
