摘要
由于智能网联汽车LTE-V2X功能对安全预警、自动驾驶的重要作用,如何定量准确评估汽车无线通信能力是智能网联汽车测评领域的关注点。其中,汽车通信能力除了受自身芯片能力及天线系统增益的制约外,还受到外界无线信道环境的影响。本文针对前期LTE-V2X功能实际道路测试中发现的通信中断问题,选取了3个典型道路场景,对LTE-V2X终端的通信距离、丢包率等数据进行采集与分析,下一步将对采集到的无线信道环境进行信道建模与试验室复现,为智能网联汽车通信可靠奠定基础.
As the LTE-V2X function of intelligent connected vehicle plays an important role in safety warning and automatic driving,how to quantitatively and accurately evaluate the wireless communication capabilities of vehicle is the focus of intelligent connected vehicle's evaluation.The vehicle communication capability is not only restricted by its own chip capability and antenna system gain,but also affected by the external wireless channel environment.Aiming at the communication interruption problem found in the actual road test of the LTE-V2X function in the early stage,this paper selects three typical road scenarios to collect and analyze data such as the communication distance and packet error rate.Next,channel modeling and laboratory reproduction of the collected wireless channel environment will be implemented,which is the basis of the reliable communication of intelligent connected vehicle.
