The invention discloses an intelligent intersection cooperative path planning system, and provides an innovative solution for the path planning problem of an automatic driving vehicle under the condition of no lane line at a complex intersection. The system monitors traffic conditions and vehicle information in real time through roadside sensing equipment arranged at an intersection. A real-time local map is generated through a data fusion algorithm, and the map reflects the road structure, the road surface condition and the vehicle distribution. The system sets lane priorities according to a traffic accident handling mode to ensure orderly passing of vehicles at the intersection. The path planning algorithm generates an optimal path for the autonomous vehicle in combination with the real-time map and the priority. And the generated path information is broadcasted through the vehicle-mounted communication system, and the vehicle performs path adjustment according to the path information to avoid collision and conflict. A fault-tolerant mechanism responds to a sensing system fault, and traffic safety is guaranteed.

    本发明公开了一种智能交叉路口协同路径规划系统,针对自动驾驶车辆在复杂路口无车道线情况下的路径规划问题提供了创新解决方案。该系统通过在交叉路口布置的路侧感知设备实时监测交通状况和车辆信息。通过数据融合算法生成实时本地地图,该地图反映了道路结构、路面状况和车辆分布。系统根据交通事故处理方式设定车道优先级,确保交叉路口车辆有序通行。路径规划算法结合实时地图和优先级,为自动驾驶车辆生成最佳路径。生成的路径信息通过车载通信系统广播,车辆根据路径信息进行路径调整,避免碰撞和冲突。容错机制应对感知系统故障,保障交通安全。
