PROBLEM TO BE SOLVED: To improve fuel consumption while securing travelling safety of a vehicle.SOLUTION: In a vehicle control device which is mounted in a vehicle and controls a movable aerodynamic member capable of vertically changing force transmitted to a vehicle by receiving traveling wind, when the occurrence of idle is not estimated (S2), a driving wheel is not actually idled (S3), a vehicle is not turned (S4) and a vehicle is not in a braking state (S5), since running safety of the vehicle is secured, ground contact pressure of a wheel is reduced to reduce rolling resistance by setting a movable aerodynamic member to cause lift in which force transmitted to the vehicle is directed upward. When a road surface condition is estimated not to be bad even though a driving wheel is actually idled (S7), when a side slip is prevented even during turning of the vehicle (S8), or when no slip by a wheel rock occurs during vehicle breaking (S9), running safety of the vehicle is secured, but slip or the like may be caused, so that the movable aerodynamic member is set to a neutral position in which force transmitted to the vehicle approaches to zero. |
