PROBLEM TO BE SOLVED: To make responsiveness of lateral acceleration of a vehicle body compatible with damping performance of yaw rate by a connection control of the lateral acceleration and the yaw rate. SOLUTION: A front wheel steering angle calculation means 14 calculates a front wheel steering angleδf to obtain a target lateral acceleration based on a steering wheel steering angleδ, vehicle speed V and the lateral acceleration YG, and generates the front wheel steering angleδf with a steering actuator 13. A yaw rate moment calculation means 15 calculates a yaw rate moment Mz based on a damping factor D and a yaw rateγto obtain a target yaw rate damping ratio. Since it generates the yaw moment Mz added with a differential element and a delay element by a differential limiting device 11 or a direct yaw moment control means 12, while improving the responsiveness of the lateral acceleration YG relative to the steering wheel steering angleδ, and the damping performance of the yaw rateγcan be also improved.
