A vehicle control device including a motion condition detector detecting motion conditions including a rotational motion and a longitudinal acceleration of a vehicle on which a load is to be loaded, a wheel load acquisition unit acquiring wheel loads of wheels, a loading state acquisition unit acquiring a loading state of the load loaded on the vehicle, an inertia value calculator calculating an inertia value including principal axes of inertia about a center of gravity of the vehicle with the load included, based on the acquired loading state, and a controller performing overturning prevention control that suppresses an increase in difference between the wheel loads of front and rear wheels of the vehicle, using the acquired wheel loads of the wheels, the inertia value, and detection values of the motion conditions.
