Beschreibung
Zusammenfassung:	When either one of a vehicle target braking/driving force and a target yaw moment cannot be achieved by a braking/driving forces of wheels, a distribution ratio is calculated to be a small value as a value indicating an acceleration or deceleration operation by a driver increases, and to be a great value as a value indicating a steering operation by a driver increases, for example. A straight line closest to a point of the target braking/driving force and the target yaw moment is specified, among sides of a quadrangle or hexagon indicating a range of the braking/driving force and yaw moment attainable by the braking/driving forces of the wheels in a rectangular coordinate of the braking/driving force and the vehicle yaw moment. The value of the coordinate at the target point, which is an internally dividing point of the straight line based upon the distribution ratio, is defined as the target braking/driving force after the modification and the target yaw moment after the modification, whereby the target braking/driving force and the target yaw moment are modified with the ratio based upon the condition of the driving operation by a driver.
