To change a pedal reaction force without deteriorating the operability of a pedal or causing uncomfortable feeling.SOLUTION: When a return condition for lowering a second reaction force to the first reaction force while the second reaction force has been set is satisfied (at a time point t3), a pedal reaction force that may be lowered from the second reaction force to the first reaction force is lowered, and a lowering gradient D in this case is set gently. The lowering gradient D may be a gradient determined based on a pedal opening degree, a pedaling force, an elapsed time, a predetermined function, or the like. By lowering the pedal reaction force gently, a driver avoids or suppress uncomfortable feeling, and deterioration of pedal operating feeling and operability is prevented.SELECTED DRAWING: Figure 6

    【課題】ペダルの操作性を悪化したり、違和感を生じたりすることなく、ペダル反力を変化させる。【解決手段】第2反力が設定されている状態で第2反力を前記第1反力に低下させる復帰条件が成立した場合(t3時点)、第2反力から第1反力に向けて低下するペダル反力を低下させ、その場合の低下勾配Dを緩やかに設定する。その低下勾配Dは、ペダル開度や踏力もしくは経過時間あいは所定の関数などに基づいて決まる勾配であってよく、ペダル反力の低下が緩やかであることにより、運転者は違和感を抱くことが回避もしくは抑制され、またペダルの操作感や操作性が悪化することがない。【選択図】図6
