蜂窝车联网(C-V2X)及其赋能智能网联汽车发展的辩思与建议

Critical thinking and suggestions on C-V2X with the developments of intelligent connected vehicles

首先简要回顾了我国企业主导的蜂窝车联网(cellular vehicle-to-everything,C-V2X)国际标准,该标准解决了车车间及车路间的低时延和高可靠通信难题,兼具技术和产业优势,在全球产业竞争中已形成领先优势。在澄清车联网的相关概念、5G与C-V2X、车联网与车路协同、车联网与无人驾驶、单车智能与网联智能等相互关系的同时,阐述了本文的观点。进而,为抓住全球汽车产业革命和我国交通产业变革的重大战略机遇期,提出了我国基于5G+C-V2X的“聪明的车+智慧的路+协同的云”的车路云协同创新发展模式,实现智能网联汽车从智能网联辅助驾驶到智能网联无人驾驶及与智能交通融为一体的发展路径。最后,分析了相关产业进展情况与存在的问题,并提出相应的政策建议。

C-V2X(cellular vehicle-to-everything)is the international standards dominated by China’s enterprises for V2X wireless communications.Based on a brief review of C-V2X,it was indicated that C-V2X could provide capabilities such as low-latency and high-reliability for communications between vehicles and the surrounding traffic elements.C-V2X has demonstrated an obvious surpassing international technological trend and industrial competitions because of technical advantages.The related concepts of V2X,the relationship between 5G and C-V2X,the relationship between V2X and vehicle-infrastructure cooperation,the relationship between V2X and self-driving vehicles as well as the relationship between individual vehicle with intelligence and connected vehicles with cooperative intelligence,were clearly clarified.The insights about the development of C-V2X and intelligent connected vehicles(ICV)were presented.Facing the great strategic opportunities of global automobile industry revolution and China’s transportation industry reform,the innovative development mode of vehicle-infrastructure-cloud cooperation based on“5G+C-V2X”was proposed accordingly.Finally,the industrial progresses and problems were discussed with corresponding policy suggestions.
