摘要
近年来,随着无线通信技术的发展,车用无线通信(V2X)技术的性能优势逐渐受到重视,该技术可以有效弥补单车感知缺陷,并结合基础设施建设,打造智慧交通系统。文章对比分析V2X技术两大发展路线,阐述长期演进(LTE)-V2X各主要通信方式,基于现行LTE-V2X网络架构,设计了一种将V2X技术引入软件定义的通信恢复功能模块,可有效提高通信效率,保证链路正常切换和恢复。
The performance benefits of vehicle to everything(V2X) communication technology have slowly come to be appreciated in recent years.This technology communication technology can not only effectively make up for sensor defects of single car autonomous driving,but also combine with infrastructure construction to create intelligent transportation systems.In this paper,the two major development routes of V2X technology are compared and analyzed,and the main communication modes of long term evolution(LTE)-V2X are described.Based on the current LTE-V2X network architecture,a software-defined communication recovery function module is designed to introduce into V2X technology,which can effectively improve the communication efficiency and ensure normal link switching and recovery.
