Abstract: In recent years, the automobile industry has developed rapidly. With the support of national strategic goals such as carbon neutralization and carbon peaking, electric vehicles are increasing. With the large capacity battery, the vehicle weight will increase while bringing long endurance, and the vehicle stability and comfort will decrease accordingly. The all-wheel interconnected suspension described in this paper studies how to improve the vehicle's driving stability and comfort. The damper of the whole vehicle is connected through the hydraulic pipeline, and the flow is controlled by the flow limiting valve. By identifying the driving attitude of the vehicle and the driver's intention, the pressure of the specific pipeline is adjusted, so as to improve the damping under specific circumstances, and reduce the vehicle's roll pitch without losing the vehicle's comfort, thereby enhancing the vehicle's stability and improving the vehicle's handling.

摘要： 近年来汽车产业发展迅猛，在碳中和碳达峰等国家战略目标的支持下，电动车日益增 多，大容量电池在带来长续航的同时也使车重随之增加，车辆稳定性以及舒适性相应下降。 文章所描述的全轮互联悬挂就如何提高车辆的行驶稳定性以及舒适性进行研究，将全车的阻 尼器通过液压管路进行连接，并用限流阀进行流量控制，通过识别汽车行驶姿态以及驾驶员 意图，对特定管路的压力进行调节，从而改善特定情况下的阻尼，在不损失汽车舒适性的前 提下降低车辆的侧倾仰俯，从而增强车辆稳定性，提升汽车的操控性。
