The invention discloses an automobile chassis automatic lifting method based on road surface change and a related device. The method comprises the steps that road surface data of a laser radar and image data collected by a camera are obtained; a road surface reference straight line is obtained through road surface data of the laser radar, and the road surface flatness is judged by comparing the road surface reference straight line with image data collected by the camera; road danger early warning is carried out through a driving program, and meanwhile the height of a chassis is increased; and after the vehicle chassis ascends, continuing to detect the flatness of the front road surface, if the flatness is uneven, keeping the height of the chassis, and otherwise, restoring the height of the chassis. When the device is used for assisting manual driving, a driver can be reminded of the front road condition, so that the driver can timely adjust the speed and automatically lift the chassis, and vehicle bumping or distress caused by the fact that the driver is neglected from observation is prevented; meanwhile, when the system is used for an automatic driving system, early warning can be conducted on the decision module, the system can automatically adjust the vehicle speed and lift the chassis conveniently, and driving comfort and safety are guaranteed.

    基于路面变化的汽车底盘自动升降方法及相关装置,包括:获取激光雷达的路面数据和摄像头采集的图像数据;通过激光雷达的路面数据得到路面基准直线,用路面基准直线和摄像头采集的图像数据进行对比判断路面平整度;通过驾驶程序进行道路险情预警,同时调高底盘高度;车辆底盘上升后,继续检测前方路面道路的平整度,若为不平整时,保持底盘高度,否则还原底盘高度。本发明当用于辅助人工驾驶时,可以提醒驾驶员前方道路情况,以便于驾驶员及时作出调整速度,自动升降底盘,防止因驾驶员疏于观察导致的车辆颠簸或遇险;同时也可用于自动驾驶系统时,可以对决策模块作出预警,方便系统自主调节车速,升降底盘,保障行驶舒适与安全。
