The present invention achieves a transmission speed in a transmission device while alleviating engagement shock in an engagement device even if the traveling velocity of a vehicle traveling in a neutral state changes. The transmission device changes the rate of rotation of a transmission input member drive-linked to an internal combustion engine in accordance with the transmission speed and transmits the rotation to a transmission output member drive-linked to a wheel. If a transmission speed is to be achieved in the transmission device while the wheel is in rotation and while the vehicle is in neutral traveling state, a vehicle control device executes torque reduction processing for reducing the output torque (Teg) of the internal combustion engine with respect to a requested torque which is the torque of the internal combustion engine according to the accelerator opening, and such torque reduction processing is carried out on the basis of the change over time in the output synchronization rate of rotation (
