The invention provides a reaction force control device for a pedal which changes the pedal reaction force without deteriorating the operability of a pedal or generating a sense of discomfort. In a state in which the second reaction force is set, when a recovery condition for decreasing a second reaction force to a first reaction force is satisfied (t3 time point), a pedal reaction force decreasing from the second reaction force to the first reaction force is decreased, and a rate D in this case is set slowly. The rate D is determined based on a depression of the pedal, a pedal force applied to the pedal, an elapsed time, or a predetermined function. The reduction of the pedal reaction force is slower, so that the driver can be prevented from feeling uncomfortable, and the operation feeling and operability of the pedal are not deteriorated.
本发明提供一种踏板反作用力控制装置,在不会使踏板的操作性变差或者产生违和感的情况下使踏板反作用力变化。在设定为第二反作用力的状态下,在使第二反作用力下降至上述第一反作用力的恢复条件成立的情况下(t3时间点),使从第二反作用力向第一反作用力下降的踏板反作用力下降,较缓地设定该情况下的下降梯度D。该下降梯度D可以是基于踏板开度、踏力或经过时间或预定的函数等而决定的梯度,通过踏板反作用力的下降较缓,能够避免或抑制驾驶员感到违和感,另外,踏板的操作感和操作性不会变差。
