The invention discloses a low-speed cross-country cruise speed control method and system. The method comprises the following steps: acquiring elevation information of obstacles in front of a vehicle; setting a correction coefficient of a target control vehicle speed according to the obstacle elevation information; determining a second cruise speed according to the correction coefficient; and controlling the vehicle to pass through the obstacle at the second cruise vehicle speed. In the low-speed cross-country cruise mode, the vehicle keeps cruise driving at the first cruise speed, the vehicle can automatically reduce the cruise speed in time and slowly pass when encountering an obstacle in the front, personnel injury or vehicle damage caused by too high speed is avoided, and therefore dynamic adaptive adjustment of the cruise speed along with the height of the road obstacle is achieved; a driver only needs to operate a steering wheel without worrying about the influence of obstacles, the vehicle automatically passes through the obstacles at a slow speed, and the trafficability and the running stability and safety of the vehicle in the low-speed cross-country cruise process are improved.

    本发明公开了一种低速越野巡航车速控制方法及系统。该方法包括获取车辆行驶前方的障碍物高程信息;根据所述障碍物高程信息设定目标控制车速的修正系数;根据所述修正系数确定第二巡航车速;控制车辆以所述第二巡航车速通过该障碍物。车辆在低速越野巡航模式下,保持第一巡航车速巡航行驶,当前方遇到障碍物,车辆能适时自动降低巡航车速,缓慢通过,避免车速过快造成人员伤害或车辆损坏,从而实现巡航车速随道路障碍物高度的动态适配调整,使得驾驶员只需操纵方向盘,不必担心障碍物的影响,车辆自动实现以缓慢的速度通过障碍物,提高低速越野巡航过程中的车辆通过性和行驶平稳安全性。
