The invention relates to a vehicle roll driving device and an active roll vehicle, belongs to the technical field of vehicle chassis, and particularly relates to the technical field of vehicle roll driving and control. The vehicle roll driving device is formed by a roll mechanism and a steering mechanism, the movement amount of a sliding block relative to a vehicle body is actuating displacement u, when the actuating displacement u is changed, the roll angle beta is changed, a roll function beta = f(u) of the relation between the roll angle beta and the actuating displacement u is obtained, vehicle roll is achieved, a linear displacement actuator is adopted to drive the vehicle to roll, the actuating displacement u and the steering angle theta serve as control parameters, and independent control over vehicle body roll and vehicle steering is achieved. The device is applied to roll driving and control of the active roll vehicle, so that the vehicle automatically inclines by a certain angle to resist centrifugal force or roll-over force when turning over a corner or running over an inclined road surface, and a stable running posture is kept.
本发明涉及一种车辆侧倾驱动装置及主动侧倾车辆,属于车辆底盘技术领域,特别涉及车辆侧倾驱动及控制技术范畴,由侧倾机构和转向机构形成车辆侧倾驱动装置,滑块相对车身移动量为致动位移u,致动位移u改变时、侧倾角β变化,获得侧倾角β与致动位移u关系的侧倾函数β=f(u),实现车辆侧倾,采用线性位移致动器驱动车辆侧倾运动,以致动位移u和转向角θ为控制参数,实现车身侧倾与车辆转向独立控制;应用于主动侧倾车辆的侧倾驱动、控制,以便车辆在过弯时或者驶过倾斜路面时自动倾斜一定角度来抵抗离心力或侧翻力,以保持稳定的行驶姿态。
