To suppress the destabilization of a behavior of a vehicle in the vicinity of a limit area, in the vehicle in which a roll stiffness distribution is changed according to a roll state.SOLUTION: A roll control device of a vehicle comprises a pair of left and right active suspensions for imparting vertical forces to left and right wheels of a rear axle of the vehicle at a reverse phase, and a controller for controlling the active suspensions. The controller increases a control amount of the active suspensions so as to increase the roll stiffness of the rear axle according to an increase of lateral acceleration which acts on the vehicle. Then, when the lateral acceleration is increased up to a high-acceleration area while exceeding a low-acceleration area, the controller lowers a gain of the control amount of the active suspensions with respect to the lateral acceleration according to the increase of the lateral acceleration.SELECTED DRAWING: Figure 2

    【課題】ロール状態に応じてロール剛性配分が変化する車両において限界域付近で車両の挙動が不安定になることを抑制する。【解決手段】車両のロール制御装置は、車両の後軸の左右の車輪に対して上下方向の力を逆相で付与する左右一対のアクティブサスペンションと、アクティブサスペンションを制御するコントローラとを備える。コントローラは、車両に作用する横加速度の増大に応じて後軸のロール剛性を増大させるようにアクティブサスペンションの制御量を増大させる。そして、横加速度が低加速度域を超えて高加速度域まで増大した場合、コントローラは、横加速度の増大に応じて横加速度に対するアクティブサスペンションの制御量のゲインを低下させる。【選択図】図2
