When an ECU carries out vehicle yaw motion control on such a vehicle that a conversion rate of converting the braking/driving force into a vertical force is larger on rear wheels than on front wheels, a driver-requested braking/driving force is distributed to the four wheels so that a distribution ratio is larger for the rear wheels than for the front wheels. Thus, when roll control necessary as a result of the vehicle yaw motion control is carried out, a target braking/driving force of a turning outer wheel for which the largest control driving force is required becomes hard to reach a driving limit. From the foregoing, when vehicle motion control is carried out with use of a braking/driving force of each wheel, each wheel is prevented from reaching a driving force limit as much as possible.
