A vehicle orientation control device is provided in a four wheel drive vehicle capable of applying braking and driving force to each of the vehicle wheels. The vehicle orientation control device (24) is provided in a vehicle control device (10) for controlling the four wheel drive vehicle and includes a standard yaw rate calculating unit (25), a yaw rate sensor (22), a target yaw moment calculating unit (26), a braking and driving force commanding unit (15), and a yaw moment control unit (27). The yaw moment control unit (27) includes an allocation ratio varying unit (27a) for continuously changing the front and rear allocation ratio of the yaw moment control torque to be distributed to the front and rear wheels (3) and (2) in dependence on the detected actual yaw rate that is detected by the yaw rate sensor (22).
