Summary:To provide a vehicle behavior control device that performs control so that deceleration is applied to a vehicle and control so that a yaw moment is applied to the vehicle, which suppresses control from intervening excessively in the whole of the vehicle.SOLUTION: In a vehicle behavior control device equipped with a driving control system 4 and a braking control system 18, a PCM 14, when a steering angle increases, sets additional deceleration to be added to the vehicle and performs control of the driving control system 4 for achieving the additional deceleration; and when the steering angle decreases, sets a yaw moment in a direction opposite to a yaw rate generated in the vehicle as a target yaw moment which should be applied to the vehicle and performs control of the brake control system 18 for applying the target yaw moment to the vehicle. In particular, the PCM 14, when the steering angle is 0, sets the target yaw moment to 0 and stops controlling by the brake control system 18.SELECTED DRAWING: Figure 2 【課題】減速度を車両に付与する制御及びヨーモーメントを車両に付与する制御を行う車両の挙動制御装置において、車両全体として制御介入が過剰な状態になることを抑制する。【解決手段】駆動制御システム４及びブレーキ制御システム１８を備えた車両の挙動制御装置において、ＰＣＭ１４は、操舵角が増大している場合に、車両に付加すべき付加減速度を設定して、この付加減速度を実現するための駆動制御システム４の制御と、操舵角が減少している場合に、車両に発生しているヨーレートとは逆回りのヨーモーメントを、車両に付与すべき目標ヨーモーメントとして設定して、この目標ヨーモーメントを車両に付与するためのブレーキ制御システム１８の制御と、を行う。特に、ＰＣＭ１４は、操舵角が０であるときに、目標ヨーモーメントを０に設定して、ブレーキ制御システム１８による制御を終了させる。【選択図】図２
