Abstract: In This paper, the development trend of automatic driving business, the limitations of single vehicle intelligence, and the advantages of vehicle road coordination are introduced. At the same time, it focuses on the technical architecture and system requirements of vehicle road collaboration, the multi-level multi-source data fusion perception analysis architecture based on "end edge cloud", and the implementation path of three-level/four-level edge deployment based on roadside+edge cloud + regional/central cloud. The networking scheme of multi-level multi-source sensing fusion analysis capability based on edge cloud is then proposed, and its specific functions and delay requirements are discussed in detail. This research is of some reference value to the project planner and designer of vehicle road collaboration.
Key words : edge cloud collaboration;vehicle-road collaboration;V2X;edge computing;MEC

    車路協(xié)同典型應用場景可分為安全、效率、定位、視頻、信息服務五大類[1],每類里面有多個典型的應用。當前各功能場景多以視頻為核心的多源數(shù)據(jù)融合通過信號處理、視頻識別、激光雷達信號識別、信息綜合等應用功能對交叉路口周邊內(nèi)的車輛、行人等位置、速度、方向角度等進行分析和預測,但不同場景下信息融合對算力、時延、安全、管控等要求各異,且傳統(tǒng)交通信息服務廠商多在路邊部署工控機方式來做融合處理,無法滿足全場景需求。隨著5G、邊緣計算的部署發(fā)展,車路邊云協(xié)同融合成為可能,能更好地滿足各場景對算力、存儲、時延、安全等需求。本文重點討論5G下邊云協(xié)同的V2X技術(shù)實現(xiàn)方案等。
