The invention relates to the technical field of vehicle active safety, and provides an anti-roll moment distribution control method, which specifically comprises the following steps of: in a vehicle driving process, detecting a lateral acceleration ay of a vehicle in real time; an ideal roll angle # imgabs0 # under the current lateral acceleration ay is determined, the current vehicle body roll angle # imgabs1 # of the vehicle is detected, the difference value between the ideal roll angle # imgabs2 # and the current vehicle body roll angle # imgabs3 # serves as the input of a PID controller, the PID controller outputs the anti-roll torque # imgabs4 # currently needed by the vehicle, and the vertical load transfer amount delta Wf of a front suspension and the vertical load transfer amount delta Wr of a rear suspension are calculated; the anti-roll moment # imgabs5 is distributed to the front suspension and the rear suspension based on the vertical load transfer amount of the front suspension and the rear suspension. According to the vehicle suspension vertical load transfer amount, an anti-roll moment distribution method is designed, and roll stiffness of the front suspension and the rear suspension is further adjusted through stabilizer bars of the front suspension and the rear suspension, so that excessive steering amount of a vehicle is reduced, insufficient steering amount is increased, and active safety of vehicle driving is effectively improved.

    本发明涉及车辆主动安全技术领域,提供了一种抗侧倾力矩分配控制方法,该方法具体如下:车辆行驶过程中,实时检测车辆的侧向加速度ay,确定当前侧向加速度ay下的理想侧倾角#imgabs0#检测车辆当前的车身侧倾角#imgabs1#将理想侧倾角#imgabs2#与当前的车身侧倾角#imgabs3#的差值作为PID控制器的输入,PID控制器输出车辆当前所需的抗侧倾力矩#imgabs4#计算前悬架的垂直载荷转移量ΔWf以及后悬架的垂直载荷转移量ΔWr,基于前悬架、后悬架的垂直载荷转移量将抗侧倾力矩#imgabs5#分配给前悬架和后悬架。根据车辆悬架垂直载荷转移量设计抗侧倾力矩分配方法,进而通过前、后悬架的稳定杆来进进一步调节前后悬架的侧倾刚度,以此减少车辆过多转向量,增加不足转向量,有效提高车辆行驶的主动安全性。
