The invention discloses a vehicle body posture adjusting method and system, and the method comprises the steps that: a vehicle body displacement detection value, a vehicle body angle detection value and a vehicle body acceleration detection value are obtained respectively, the displacement conversion compensation amount of a vehicle body is calculated through a control module according to the displacement detection value, and the angle conversion compensation amount of the vehicle body is calculated according to the angle detection value; the acceleration conversion compensation amount of the vehicle body is calculated according to the acceleration detection value; the control module carries out vehicle body posture adjustment judgment according to the displacement conversion compensation amount, the angle conversion compensation amount and the acceleration conversion compensation amount and outputs decoupling and distribution, the actual overall compensation amount of a vehicle body is determined, compensation needing to be carried out by the whole vehicle needs to be converted into compensation motion of the whole specific actuator, and the compensation motion is adjusted. The control module controls the vertical damping actuator, the transverse damping actuator and the longitudinal damping actuator to output compensation motion according to the actual overall compensation amount, compensation control is conducted on the vehicle in the vertical direction, the transverse direction and the longitudinal direction, and the comfort of passing through a curve road section is improved.

    本发明公开一种车体姿态调节方法及车体姿态调节系统,分别得到车体的位移检测值、车体的角度检测值、车体的加速度检测值,控制模块根据位移检测值计算车体的位移转化补偿量,根据角度检测值计算车体的角度转化补偿量,根据加速度检测值计算车体的加速度转化补偿量;控制模块根据位移转化补偿量、角度转化补偿量、加速度转化补偿量进行车体姿态调节判断,并输出解耦与分配,确定车体的实际整体补偿量,整个车辆所要进行的补偿需要转化为整个具体的作动器的补偿运动,控制模块根据实际整体补偿量,控制垂向阻尼作动器、横向阻尼作动器和纵向阻尼作动器输出补偿运动,分别从垂向、横向、纵向上对车辆进行补偿控制,提升通过曲线路段的舒适性。
