The invention relates to the technical field of vehicle control, in particular to a vehicle suspension height self-adaption method and system. The vehicle suspension height self-adaption method comprises the steps that based on the running state of a vehicle, first road condition information in front of the vehicle is obtained at a first preset frequency; acquiring the speed of the vehicle and the distance from the vehicle to the uphill road section at a second preset frequency based on the uphill road section included in the first road condition information; controlling a front suspension of the vehicle to be compressed by a first height based on the fact that the ratio of the distance to the vehicle speed is smaller than the preset duration; if the distance is smaller than the preset length, controlling a rear suspension of the vehicle to extend by a second height, and acquiring second road condition information behind the vehicle; and based on the second road condition information that the rear wheels of the vehicle are located on the uphill road section, a rear suspension of the vehicle is controlled to be compressed at a preset speed until the compression amount reaches a third height. The suspension height self-adaption system for the vehicle is applied to the suspension height self-adaption method for the vehicle, and therefore the problem that the road holding force is insufficient when a commercial vehicle climbs a slope is solved.

    本发明涉及车辆控制技术领域,具体而言,涉及一种车辆用悬架高度自适应方法及系统。车辆用悬架高度自适应方法包括:基于车辆处于行驶状态,以第一预设频率获取车辆前方的第一路况信息;基于第一路况信息包含上坡路段,以第二预设频率获取车辆的车速及车辆至上坡路段的距离;基于距离与车速的比值小于预设时长,控制车辆的前悬架压缩第一高度;基于距离小于预设长度,控制车辆的后悬架伸长第二高度,并获取车辆后方的第二路况信息;基于第二路况信息包括车辆的后轮位于上坡路段,控制车辆的后悬架以预设速度压缩,直至压缩量达到第三高度。车辆用悬架高度自适应系统应用于车辆用悬架高度自适应方法,这样就解决了商用车爬坡时抓地力不足的问题。
