The invention relates to a vehicle semi-active suspension integrated control method and a control system. The method comprises the following steps: obtaining control damping to control a suspension: if a vehicle is about to roll laterally, enhancing the damping according to lateral acceleration, and then controlling the suspension; if the vehicle is about to pitch, enhancing the damping according to the longitudinal acceleration, and then controlling the suspension; and if the vehicle is about to roll and pitch, enhancing and superposing the damping according to the lateral acceleration and the longitudinal acceleration to serve as control damping to control the suspension. According to the method, roll and pitch principles are combined, the suspension damping is actively adjusted according to a vehicle body posture (pitch and roll) in the vehicle driving process, intervention is performed in advance, roll and pitch of the vehicle body are effectively restrained on the basis that vehicle riding comfort and driving safety are both considered, and the stability of the vehicle driving posture is improved.
本发明涉及一种车辆半主动悬架集成控制方法及控制系统,方法按照如下步骤得到控制阻尼对悬架进行控制:若车辆即将侧倾,则将阻尼根据侧向加速度增强后对悬架进行控制;若车辆即将俯仰,则将阻尼根据纵向加速度增强后对悬架进行控制;若车辆即将侧倾且即将俯仰,则将阻尼分别根据侧向加速度和纵向加速度增强并叠加后作为控制阻尼对悬架进行控制。本发明的方法结合侧倾和俯仰原理,针对车辆行驶过程中车身姿态(俯仰和侧倾)主动进行悬挂阻尼的调节,提前进行干预,在兼顾车辆乘坐舒适性和行驶安全性的基础上,有效抑制了车身的侧倾和俯仰,改善车辆行驶姿态的稳定。
