The invention discloses an air suspension self-adaptive adjusting method based on a front camera. The method comprises the steps that (1) whether a vehicle is in a forward gear currently or not is detected; (2) if the detection result is yes, forming an estimated driving area within a front set distance according to the current vehicle speed and the lateral angle; (3) extracting a road surface image in the driving area from the front road surface image, and extracting an obstacle and an obstacle height in the driving area based on the road surface image in the driving area; and (4) calculating the bumping coefficient of the front road surface according to the height of the obstacle, determining the damping and rigidity of the air suspension based on the bumping coefficient of the front road surface, and adjusting the air suspension to the determined damping and rigidity. The highest height of the obstacle in the estimated driving area and the road bumping coefficient are obtained through the front camera, the height, rigidity and damping of the air suspension are adjusted in advance, adjustment of the air suspension has perspectiveness and self-adaptability, and the comfort and safety of the vehicle are improved.

    本发明公开一种基于前置摄像头的空气悬架自适应调节方法,包括:(1)检测车辆当前是否为前进挡;(2)若检测结果为是,则根据当前车速及侧向角形成前方设定距离内的预估行驶区域;(3)在前方路面图像中提取行驶区域内的路面图像,基于行驶区域内的路面图像来提取行驶区域内的障碍物及障碍物高度;(4)根据障碍物高度计算前方路面的颠簸系数,基于前方的路面颠簸系数确定空气悬架的阻尼及刚度,并调节空气悬架至确定的阻尼及刚度。利用前置摄像头获取预估行驶区域内障碍物的最高高度及路面颠簸系数,提前调节了空气悬架的高度、刚度及阻尼,使得空气悬架的调节具有前瞻性和自适应性,提升了车辆的舒适性及安全性。
