The invention discloses an active anti-rollover method for a trailer, which adopts an active anti-rollover device for the trailer, and the active anti-rollover device comprises an axle body, a left wheel axle, a right wheel axle, a left hydraulic actuator, a right hydraulic actuator and a frame, in the running process of the vehicle, when the risk of right turning is faced, the left hydraulic actuator is controlled to be shortened, the left hydraulic actuator drives the left wheel axle to drive the left wheel to move upwards, meanwhile, the right hydraulic actuator is controlled to be extended, the right hydraulic actuator drives the right wheel axle to drive the right wheel to move downwards, and then the gravity center of the vehicle deviates leftwards; and when the risk of left turning is faced, the left hydraulic actuator is controlled to extend, so that the left hydraulic actuator drives the left wheel axle to drive the left wheel to move downwards, and meanwhile, the right hydraulic actuator is controlled to shorten, so that the right hydraulic actuator drives the right wheel axle to drive the right wheel to move upwards, and the center of gravity of the vehicle shifts rightwards.

    本发明公开了一种挂车主动防侧翻方法,该方法采用一种挂车主动防侧翻装置,装置包括车桥本体、左侧车轮轴、右侧车轮轴、左侧液压动作器、右侧液压动作器和车架;车辆行驶过程中,当面临右侧翻风险时,控制左侧液压动作器缩短,使左侧液压动作器驱动左侧车轮轴带动左侧车轮上移,同时,控制右侧液压动作器伸长,使右侧液压动作器驱动右侧车轮轴带动右侧车轮下移,进而使车辆重心向左偏移;当面临左侧翻风险时,控制左侧液压动作器伸长,使左侧液压动作器驱动左侧车轮轴带动左侧车轮下移,同时,控制右侧液压动作器缩短,使右侧液压动作器驱动右侧车轮轴带动右侧车轮上移,进而使车辆重心向右偏移。
