The invention belongs to the field of automobiles, and particularly relates to a height adjusting method for an automobile carrying an air suspension. The current height h of the air suspension is obtained, the target height h'of the height of the air suspension is obtained, and the adjusting direction of the air suspension is obtained according to the current height and the target height; (1) if the height sensor does not fail, the height of the air suspension detected by the height sensor is matched with the air suspension to complete adjustment of the adjusting height; and (2) if the height sensor breaks down, adjusting the adjusting height by matching with the air suspension through air bag parameters of the air suspension. According to the method, when the height sensor breaks down, the height of the front and rear shafts of the air suspension can be accurately adjusted, and the safety of an automobile is improved.

    本发明属于汽车领域,具体涉及一种搭载空气悬架的汽车高度调节方法。获得空气悬架的当前高度h,获得空气悬架高度的目标高度h′,根据所述当前高度和目标高度得到空气悬架的调节方向;检测高度传感器是否故障:(1)若高度传感器未故障,则通过高度传感器检测到的空气悬架高度来配合空气悬架完成所述调节高度的调节;(2)若高度传感器故障,则通过空气悬架的气囊参数来配合空气悬架完成所述调节高度的调节。本发明方法能够在高度传感器故障时,准确调节空气悬架的前后轴高度,提高了汽车的安全性。
