摘要
随着汽车保有量快速增长,交通问题愈发严重,车联网在智能交通领域作用越来越重要。立足于车联网的定义和车载系统架构,着重介绍基于LTE-V的车载V2X系统设计关键技术和应用,包括VBOX硬件设计和软件设计,最后对V2X系统进行了实车验证,实验证明,当远车没有变道情况下预警准确率可达到100%,当远车存在不确定性变道的情况下,准确率能达到90%以上。
With the rapid growth of car ownership and traffic problems,the role of Internet of vehicles(IoV)in the intelligent transportation is becoming increasingly important.Based on the definition of IoV and the vehicle system architecture,this paper focuses on the key technologies and applications of the V2X system design based on LTE-V,including the hardware and software design of VBOX.Finally,the experiments reveal that the system is stable to achieve the desired requirements.When the remote vehicle(RV)has not changed the lane,the warning accuracy reaches 100%,and when the RV intends to change the lane with uncertainty,the accuracy reaches more than 90%.
