摘　　要：车路无线通信系统是交通运输领域数字化、智能化应用的重要组成部分,但其信道带宽资源往往受到限制。在自动驾驶等应用场景中,需要利用无线通信系统传输大量带有时间信息和空间信息的车路交互应用数据。文章在对常见的车路无线通信系统的应用特性进行分析后,提出了一种针对拓扑结构较为稳定的专用短程通信网络时空数据校准机制,并说明这一机制如何降低了时空数据校准应用对车路无线通信系统信道资源的需求。Vehicle-road wireless communication system is an important part of digital and intelligent application in the field of transportation.However,its wireless communication system bandwidth resources are often limited,but it is necessary to use this system to transmit a great deal of vehicle-road interaction data with time and space information.Based on the analysis of the application characteristics of common vehicle-road wineless communication systems,this paper proposes a time-space data calibration mechanism for dedicated short-range communication networks with stable topology,and explains how this mechanism reduces the channel resource requirements of vehicle-road wireless communication systems for time-space data calibration applications.
