The invention provides a suspension control method and device under vehicle steering, and the method comprises the steps: determining a roll angle, a pitch angle and a roll rate of a vehicle body of a target vehicle based on left front displacement, right front displacement, left rear displacement and right rear displacement; based on the roll rate and the vehicle speed of the target vehicle at the current moment, a first curve and a second curve are used for determining roll control torque; based on the roll angle and the pitch angle, using a third curve to determine a pitch control moment; determining a roll control weight coefficient and a pitch control weight coefficient by using the fourth curve and the fifth curve; and determining a driving value based on the roll control moment, the pitch control moment, the roll control weight coefficient and the pitch control weight coefficient. By means of the method and device, the problems that when the vehicle turns, the consistency performance is not high, and the control requirement and the comfort requirement cannot be well coordinated can be solved.

    本申请提供了一种车辆转向下的悬架控制方法和控制装置,所述方法包括:基于左前位移、右前位移、左后位移和右后位移,确定所述目标车辆的车身的侧倾角、俯仰角和侧倾率;基于所述侧倾率和所述目标车辆当前时刻的车速,利用第一曲线以及第二曲线,确定侧倾控制力矩;基于所述侧倾角和所述俯仰角,利用第三曲线,确定俯仰控制力矩;利用第四曲线,以及第五曲线,确定侧倾控制权重系数和俯仰控制权重系数;基于所述侧倾控制力矩、所述俯仰控制力矩、所述侧倾控制权重系数和所述俯仰控制权重系数,确定驱动值。通过所述方法和装置,能够克服车辆过弯时的一致性表现不高以及不能很好的协调操控需求与舒适需求的问题。
