When the absolute value of the road gradient resistance value |F<SB>gra</SB>| is equal to or larger than a second predetermined value F<SB>a2</SB>, the target acceleration and deceleration correction value α<SB>gra</SB>is set to have an inclination of a road gradient directional component of a gravitational acceleration (g.sinθ) and have an absolute value small for maximum acceleration αV<SB>max</SB>of the vehicle, and the saturation of the driving force can be prevented. The larger the absolute value of the road gradient resistance force |F<SB>gra</SB>| is, the larger the variation rate of the target acceleration and deceleration correction value α<SB>gra</SB>is.
