The invention relates to the technical field of automatic driving, in particular to a vehicle guiding method based on ACC and green wave traffic, and the method comprises the steps: judging whether a vehicle enters a green wave traffic scene, guiding the vehicle speed calculation according to the traffic light information transmitted by a road test RSU of the green wave traffic, and judging whether a barrier vehicle exists in front or not. Decisions of emergency braking, cruising, early warning and mild braking are made; according to the vehicle guiding method provided by the invention, through fusion of single vehicle sensing and V2X sensing, compared with a single vehicle ACC function, the monitoring distance and area are increased, and the change state of traffic lights at a front intersection can be sensed earlier; the sensing precision and accuracy are improved, and the missed judgment rate and the misjudgment rate are reduced; through more types of information sensed by V2X, the traffic efficiency is improved, and the traffic safety is ensured.
本发明涉及自动驾驶技术领域,具体涉及一种基于ACC与绿波交通的车辆引导方法,包括判断车辆是否进入到绿波交通的场景内,根据绿波交通的路测RSU发出的红绿灯信息,引导车速计算,判断前方是否存在障碍车辆,做出紧急制动、巡航、预警、温和制动的决策;本发明通过本申请的车辆引导方法,通过单车感知和V2X感知的融合,相对于单车ACC功能,增加了监控距离和区域,可更早感知前方路口交通灯变化状态;提高了感知精确度和准确度,减少了漏判率和误判率;通过V2X感知的更多种类的信息,提高通行效率及确保交通安全。
