The invention discloses a large-scale unmanned vehicle lane change cloud scheduling method based on twin lanes, and the method comprises the steps: 1, carrying out the feature extraction of a physical lane through a cloud server, and building a twin lane section model; 2, predicting a time-varying distance between a lane changing vehicle and surrounding vehicles based on a twin lane coordinate system; 3, establishing a method for calculating the priority of a single lane-changing vehicle and the relevancy between vehicles, and evaluating the joint lane-changing scheduling priority of the vehicles; and 4, the cloud server calculates and generates a parallel lane changing task queue of vehicle joint lane changing scheduling, and issues a scheduling instruction to execute target vehicle section joint lane changing scheduling. The efficient scheduling method is provided for large-scale unmanned vehicle lane changing, the safety and reliability of vehicle lane changing in a complex scene can be improved, and theoretical support is provided for construction of an intelligent traffic system.

    本发明公开了一种基于孪生车道的大规模无人驾驶车辆换道的云调度方法,包括:1云服务器对物理车道进行特征提取,建立孪生车道区段模型;2基于孪生车道坐标体系预测换道车辆与周围车辆的时变距离;3建立换道车辆单车优先级与车间相关度计算方法,评估车辆联合换道调度优先级;4云服务器计算生成车辆联合换道调度的并行换道任务队列,下发调度指令执行目标车辆区段联合换道调度。本发明为大规模无人驾驶车辆换道提供高效率的调度方法,能够提高复杂场景下车辆换道的安全性与可靠性,为智能交通系统的建设提供理论支撑。
