摘　　要：目前关于车联网的技术处于快速发展阶段,通信场景仿真分析尤为重要。然而,在车联网场景中有大量的移动节点,这使得在真实环境中进行实验变得困难。为此提出以virtual test drive(VTD)软件作为仿真平台,测试在车联网仿真环境中支持加载无线信道模型和编辑交通仿真场景,利用系统级仿真的方法输出5G网络和车联网网络对路面的覆盖情况并与实测环境进行仿真数据比对。仿真结果表明,车与基站通信(vehicle-to-network,V2N)得到的信噪比(signal-to-noise ratio,SNR)与参考信号接收功率(reference signal receiving power,RSRP)符合实测数据的预期,进而改善相较于传统车联网仿真在仿真测试与实际道路测试关联度较低的问题。At present,the technology of vehicle networking is in a rapid development stage,and simulation analysis of communication scenarios is particularly important.However,there are a large number of mobile nodes in vehicle networking scenarios,which makes it difficult to conduct experiments in real environments.This paper proposes using the software VTD(Virtual Test Drive)as the simulation platform to test the support for loading wireless channel models and editing traffic simulation scenarios in the vehicle networking simulation environment.The system level simulation method is used to output the coverage of 5G network and vehicle networking network on the road surface and compare the simulation data with the measured environment.The simulation results show that the signal-to-noise ratio(SNR)and reference signal received power(RSRP)obtained from vehicle to base station communication(V2N)meet the expectations of measured data,thereby improving the problem of low correlation between simulation testing and actual road testing compared to traditional vehicle networking simulation.
