The invention discloses an emergency lane keeping system and a control method thereof, and belongs to the field of automobile control. The emergency lane keeping system comprises a front radar sensor, a foresight camera, a left rear angle radar sensor, a right rear angle radar sensor, a lower computer and an upper computer; and the front radar sensor, the foresight camera, the left rear angle radar sensor, the right rear angle radar sensor, the lower computer and the upper computer are electrically connected together. According to the method, the three factors of the vehicle running state, the driver driving behavior and the road environment condition are comprehensively considered. The road environment information is fused with data of the camera and the radar, and not only contains related information of a front lane, but also traffic flow information of vehicles coming in the opposite direction of a near lane, rear overtaking vehicles and the like. The system is suitable for multi-terrain roads. Through addition of multi-target road environment information and fusion confirmation of vehicle targets, the driving safety is further enhanced, unconscious lane departure of the vehicle is prevented, and collision with vehicles of adjacent lanes or road edges is avoided.
本发明公开了一种紧急车道保持的系统及其控制方法,属于汽车控制领域包括:前雷达传感器、前视摄像头、左后角雷达传感器、右后角雷达传感器、下位机和上位机,所述前雷达传感器、前视摄像头、左后角雷达传感器、右后角雷达传感器、下位机和上位机通过电性连接在一起。本发明综合考虑了车辆运行状态、驾驶员驾驶行为和道路环境状况三方面因素。且道路环境信息融合了摄像头和雷达的数据,不仅包含前方车道相关信息,还有临近车道对向来车和后方超越车辆等车流信息。该系统适用于多地形道路。多目标道路环境信息的加入,车辆目标的融合确认,进一步增强驾驶的安全性,防止车辆发生无意识的车道偏离,避免与邻近车道的车辆或者道路边沿发生碰撞。
