The invention provides a vehicle four-wheel suspension independent control method and system based on road condition detection, and the method comprises the steps: judging the abnormal type and giving an alarm when the road condition in front of a vehicle is detected to be abnormal, and obtaining the real-time distance between an abnormal point of the road condition in front of the vehicle and the vehicle; according to the abnormal type of the front road condition and the real-time distance, the damping and the rigid strength of the suspension related to the abnormal point are adjusted, and the damping and the rigid strength of the other suspensions are kept unchanged; and after judging that the vehicle passes through the abnormal point, controlling the damping and rigid strength of the adjusted suspension to recover. The control mode of the air suspension can be flexibly adjusted according to the road condition when facing the complex road condition, and the stability, controllability and safety of vehicle driving are enhanced.

    本发明提供一种基于路况检测的车辆四轮悬架单独控制方法及系统,方法包括:检测车辆前方路况异常时,判断异常类型并发出告警,获取车辆前方路况异常点与自车之间实时距离;根据前方路况异常类型与所述实时距离,调整与异常点相关悬架的阻尼和刚性强度,其余悬架的阻尼和刚性强度保持不变;判定自车驶过异常点后,控制被调整悬架的阻尼和刚性强度复原。本发明的空气悬架控制方式面对复杂路况能够根据道路情况灵活地调节,增强了车辆行驶的稳定性、可操控性与安全性。
