The present invention relates to a roll control device for a vehicle, which suppresses the behavior of the vehicle from becoming unstable in the vicinity of a boundary region in a vehicle in which the roll stiffness distribution changes according to the roll state. A roll control device for a vehicle is provided with: a pair of left and right active suspensions for applying a vertical force to left and right wheels opposite to the rear axle of the vehicle; and a controller that controls the active suspension. The controller increases a control amount of the active suspension in accordance with an increase in lateral acceleration acting on the vehicle so as to increase roll stiffness of the rear axle. Furthermore, when the lateral acceleration exceeds the low acceleration range and increases to the high acceleration range, the controller reduces the gain of the control amount of the active suspension with respect to the lateral acceleration in accordance with the increase in the lateral acceleration.
本发明涉及车辆的侧倾控制装置,在侧倾刚度分配根据侧倾状态而变化的车辆中抑制车辆的举动在界限区附近变得不稳定。车辆的侧倾控制装置具备:左右一对主动悬架,以反相对于车辆的后轴的左右的车轮赋予上下方向的力;和控制器,控制主动悬架。控制器根据作用于车辆的横向加速度的增大来使主动悬架的控制量增大以使后轴的侧倾刚度增大。而且,在横向加速度超过低加速度区而增大至高加速度区的情况下,控制器根据横向加速度的增大来使主动悬架的控制量相对于横向加速度的增益降低。
