A vehicle control device includes a depression amount detection unit, a depression speed detection unit, a reaction force setting unit, and a reaction force generation unit. The reaction force setting unit sets a value of a reaction force in a manner of separating characteristics into advancement characteristics and return characteristics. The reaction force setting unit sets a value of a reaction force with respect to a depression amount in such a way that, in main advancement characteristics except for both ranges corresponding to start of depressing and end of depressing among advancement characteristics, a degree of increase of a value of a reaction force relatively decreases, as a depression amount increases until a predetermined ratio with respect to a maximum depression amount of an accelerator pedal reaches, and a degree of increase of a value of a reaction force relatively increases, as a depression amount increases after the predetermined ratio reaches; and sets a value of the reaction force in such a way that a value of the reaction force decreases, as a depression amount decreases.

Vehicle control device

An operation device in which in-vehicle devices are controlled in accordance with a rotation angle of an input unit operated by a manual operation of a driver, which includes a commander rotatable about a rotation shaft, a rotation angular speed calculation unit that detects a rotation angular speed of the commander, a motor that gives an operation reaction force for each predetermined rotation angle of the commander, and an ECU that controls the operation reaction force given by the motor, wherein the ECU changes the operation reaction force in accordance with the rotation angular speed detected by the rotation angular speed calculation unit.
