The invention relates to the technical field of automobile suspensions, in particular to an active adjusting method and system for an air suspension system and a vehicle, and aims to receive vehicle camera and radar signals and vehicle state information of the vehicle during driving and judge whether a bumpy road surface or a ponding road surface exists on a driving route of the vehicle or not. And meanwhile, roughness information of the bumpy road surface or length information of the waterlogged road surface is received, whether the vehicle needs to be lifted or not and the height needing to be lifted by the vehicle are judged according to the roughness of the road surface or the length of the waterlogged road surface, and when no continuous bumpy road surface or waterlogged road surface exists within the distance s1 in front of the vehicle, the vehicle height is restored to the normal vehicle height. Through combination with the camera and the radar, the height of the vehicle can be actively adjusted in advance in a specific scene, manual adjustment is not needed, the double-cavity air spring electromagnetic valve is closed before the height of the vehicle is adjusted, and therefore the adjusting speed can be increased, and the adjusting time can be shortened.

    本发明涉及汽车悬架技术领域,具体涉及一种空气悬架系统主动调节方法、系统及车辆,接收车辆摄像头和雷达信号,以及车辆在行驶中的车辆状态信息,判断车辆正行驶的路线上是否有坑洼路面或积水路面,同时也会接收坑洼路面的粗糙度信息或积水路面的长度信息,并根据路面粗糙度或积水路面的长度判断是否需要举升车辆及需要车辆举升的高度,当车辆前方s1距离内没有连续的坑洼路面或积水路面时,车高恢复至正常车高。通过和摄像头、雷达结合,在特定场景下可以提前主动的进行车辆高度的调节,不需要人手动调节,在车辆调节高度之前,关闭双腔空气弹簧电磁阀,从而可以提升调节的速度,减少调节时间。
