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.

车路协同典型应用场景可分为安全、效率、定位、视频、信息服务五大类[1],每类里面有多个典型的应用。当前各功能场景多以视频为核心的多源数据融合通过信号处理、视频识别、激光雷达信号识别、信息综合等应用功能对交叉路口周边内的车辆、行人等位置、速度、方向角度等进行分析和预测,但不同场景下信息融合对算力、时延、安全、管控等要求各异,且传统交通信息服务厂商多在路边部署工控机方式来做融合处理,无法满足全场景需求。随着5G、边缘计算的部署发展,车路边云协同融合成为可能,能更好地满足各场景对算力、存储、时延、安全等需求。本文重点讨论5G下边云协同的V2X技术实现方案等。
