The invention relates to an air suspension height grade adjusting method and system, and belongs to the technical field of automobiles. The air suspension height grade adjusting method comprises the following steps that a vehicle is provided with a plurality of height grades used for adjusting the height of a vehicle body; an intermediate target level is set in the interval of each height level; obtaining a target height grade and a current vehicle body height grade; selecting a middle target level between the target height level and the current vehicle body height level; and adjusting the air springs of the front axle and the rear axle to the middle target grade. Therefore, after the target height level is determined again, reversing adjustment can be carried out immediately at the position of the middle target level along with switching of the target height level, switching descending in the ascending process and switching ascending in the descending process are achieved, adjustment and switching do not need to be carried out after the target height level determined previously is completed, and the operation is simple and convenient. Therefore, the response speed of height level adjustment is accelerated, and the driving experience of a driver is improved.

    本申请涉及一种空气悬架高度等级调节方法及系统,属于汽车技术领域,该空气悬架高度等级调节方法包括以下步骤:车辆设置有多个用于调节车身高度的高度等级;各个高度等级的区间中均设置有中间目标等级;获取目标高度等级和当前车身高度等级;选取目标高度等级和当前车身高度等级之间的中间目标等级;将前桥和后桥的空气弹簧均调整至中间目标等级。因此,当目标高度等级重新确定后,随着目标高度等级的切换,在中间目标等级的位置,能立马进行换向调节,实现上升过程中切换下降以及下降过程中切换上升,不需要等到之前确定的目标高度等级完成后再进行调节切换,进而加快高度等级调节的响应速度,提高驾驶人员驾乘体验感。
