PROBLEM TO BE SOLVED: To provide a vehicle control device capable of suppressing deterioration of drivability by appropriately controlling a clutch that can be optionally engaged and disengaged.SOLUTION: A vehicle control device includes: a differential mechanism connected to an engine and a drive wheel; a first rotary machine which is connected to the differential mechanism and outputs reaction force torque against engine torque; a second rotary machine; a battery; a transmission path of power between the differential mechanism and drive wheel; a first clutch that is connected to the transmission path and second rotary machine, and can be optionally engaged and disengaged with/from them; a second clutch connected to the transmission path and second rotary machine; detection means for detecting a travel range; and a control part. The second clutch is a one-way clutch for allowing transmission of only torque in a rotation direction for moving a vehicle forward to the transmission path from the second rotary machine. In the case when the travel range is a reverse range (Yes in step S10), the control part maintains the first clutch in an engaged state (steps S20, S30), and causes the vehicle to be moved backward by torque of the second rotary machine.SELECTED DRAWING: Figure 1
