The invention belongs to the technical field of monitoring storage data processing, and particularly relates to an automobile ECAS height control method and system. According to the scheme, when it is detected that the left and right height difference of a front suspension and the left and right height difference of a rear suspension of a vehicle are both larger than a set threshold value, interconnection between air bags on the two sides of the front suspension is controlled to be closed, and the front air bag and the rear air bag located on the lower side are inflated; the height difference of the left and right air bags of the front suspension and the left and right height difference of the rear suspension are smaller than a set threshold value. According to the scheme, when it is detected that the vehicle inclines laterally, interconnection of the air bags on the two sides of the suspension is closed firstly, air path connection between the air bags on the two sides is interrupted, then the air bag on the lower side is independently controlled to be inflated, and the situation that the higher side is inflated at the same time is avoided, so that the inflation efficiency of the lower side is improved, the vehicle body height is adjusted in time, and safety is improved. And the stability of the vehicle in the running process is improved.

    本发明属于监控存储数据处理的技术领域,具体涉及一种汽车ECAS高度控制方法及系统。方案包括:当检测到车辆前悬架左、右高度差以及后悬架左、右高度差均大于设定阀值时,分别控制前悬架两侧气囊之间的互联关闭以及前悬架两侧气囊之间的互联关闭,并对位于较低侧的前、后气囊充气;直至前悬架左、右气囊的高度差以及后悬架左、右高度差均小于设定阀值。本方案在检测到车辆发生侧倾时,首先关闭悬架两侧气囊的互联,中断两侧气囊之间的气路连接,然后单独控制较低侧的气囊进行充气,避免同时给较高侧充气,从而提高了对较低侧充气的效率,及时调整车身高度,提高了车辆行驶过程中的稳定性。
