摘要
为提高交通效率、保障交通安全以及满足人们对信息服务类业务的需求,实现汽车、通信、交通各领域的协同发展,V2X技术成为了汽车智能化和网联化的重点研究方向。目前V2X通信的主要标准是DSRC标准和C-V2X标准。首先对两种标准的发展历程、网络架构、关键指标进行分析;其次对两种标准的射频指标进行解读比对;最后概述C-V2X标准的演进、产业架构,并展望我国C-V2X的发展前景。
In order to improve traffic efficiency,traffic safety and to meet the demands of information services,to meet the coordinated development of vehicle,communication and transportation,V2X standards has become one of the key research directions of vehicle intelligence and connection.At present,the main standards of V2X communications are Dedicated Short-Range Communication(DSRC)standards and cell-based mobile communication C-V2X(Cellular to Evolution)standards(including LTE-V2X and 5G-V2X).Firstly,this paper analyzes the development history,network architecture and key indexes of the two standards.Secondly,the RF(Radio Frequency)indexes of the two standards are analyzed and compared.Finally,the standards evolution and industry architectures of C-V2X technology are summarized,and the development prospect of C-V2X standards in China is forecasted.
