The invention provides a method for assisting lane changing and overtaking of a networked vehicle in a mixed sparse scene. The method comprises the following steps that the networked vehicle senses state information of a traditional vehicle on a road in real time and stores the state information; the networked vehicles traverse state information of surrounding traditional vehicles, identify lost timestamps or corresponding state information and repair the lost timestamps or the corresponding state information; establishing a vehicle state prediction model, and predicting future states of the networked vehicle and surrounding vehicles by using the vehicle state prediction model; establishing a lane-changing overtaking model, and simulating and testing a lane-changing overtaking process in advance by using the lane-changing overtaking model; and using a result output by the lane-changing overtaking model to evaluate the feasibility of the vehicle executing the lane-changing overtaking action at a certain moment in the future, and providing corresponding speed guidance for lane-changing overtaking for the vehicle with relatively high feasibility. The networking vehicle lane-changing overtaking auxiliary method can assist the networking vehicle to complete lane-changing overtaking operation, and solves the problem of how to safely and efficiently carry out lane-changing overtaking on the networking vehicle in a mixed sparse scene.

    本发明提供了一种混合稀疏场景下联网车辆变道超车辅助方法,包括如下步骤:联网车辆实时感知道路上传统车辆的状态信息并存储;联网车辆遍历周围传统车辆的状态信息,识别丢失的时间戳或相应的状态信息,并进行修复;建立车辆状态预测模型并利用所述车辆状态预测模型预测联网车辆及其周围车辆的未来状态;建立变道超车模型并利用所述变道超车模型提前仿真和测试变道超车过程;使用所述变道超车模型输出的结果来评估车辆在未来某个时刻执行变道超车动作的可行性,并对可行性较高的车辆提供变道超车相应的速度引导。该联网车辆变道超车辅助方法可辅助联网车辆完成变道超车操作,解决了联网车辆在混合稀疏场景下如何安全且高效的进行变道超车的问题。
