摘　　要：5G低时延高可靠的网络切片在车联网行业得到广泛关注,车路协同各场景的发展演进也体现了5G应用正逐步深化。从5G灵活的网络定制能力入手,分析了车路协同发展过程以及各业务场景对网络性能的需求,并基于典型的车路协同系统架构,论述车联网业务的5G网络切片实现流程,涵盖了切片创建、切片资源调度和切片安全保障等主要内容。5 G network slicing has received widespread attention in the vehicular network industry, and the development and evolution of various scenarios of vehicle-road collaboration also reflect that 5 G applications are gradually deepening. In this paper, the development process of vehicle-road collaboration and the network performance requirements are analyzed firstly. Then we present the system architecture of vehicle-road collaboration. Subsequently, implementation cases and specific processes are given out, in-cluding network slicing creation process, scheduling system for slice resources. Finally, the key technologies of network slicing to en-sure the vehicle-road collaboration security are introduced.
