Ge Yu Ming, vice president of China Information and Communication Research Institute, shared that 5G has entered a stage of large-scale development. Only three operators have now opened more than 600,000 5G base stations, and the Zhou Jianshe capacity exceeds 6.5438+0.5 million. In 2025, the total investment of 5G in China will reach10.5 trillion. The Internet of Vehicles is the empowerment of traditional industries by new generation technologies such as 5G and AI, and 5G communication technology brings more imagination to the application scenarios of vehicles. For example, the maturity of LTE—V2X technology can support the realization of some low-latency and high-reliability security early warning applications. For example, intersection collision warning, front and rear car brake warning and so on. ; The concept of intelligent cockpit: the realization of some autopilot functions and so on.
In his view, the challenges faced by the large-scale commercialization of the get-off network are not only technology, but also the need to build a new integrated industrial ecology. In the future, for the collaborative phase, it is necessary to build a highly coupled interconnected environment of people, vehicles, roads and clouds based on 5G, and realize advanced/fully automatic driving services such as vehicle-road collaborative control, vehicle-vehicle collaborative formation and remote operation, and finally support the realization of fully automatic driving.
Zhao Xinyong, general manager of Lu Hua Yi Yun Technology Co., Ltd. said that the development of car networking has brought new opportunities for intelligent transportation. The intelligent transportation of the future vehicle-road system can be roughly divided into two categories, one is urban transportation, and the other is intelligent expressway. How to develop intelligent transportation in the future? Zhao Xinyong simply summed it up as "one city, one road, one heart and one soul, cloud network cloud service, one phone and one price". Specifically, we must first realize the interconnection of transportation infrastructure, real-time perception of traffic data, and * * * enjoyment of data. Secondly, the improvement of intelligent transportation products, chips and clouds will be the main development trend of intelligent transportation system in the future, and the software architecture of urban traffic and highway management should be constructed. In addition, cloud network cloud service is mainly to establish monitoring database, query database and planning database in conjunction with large enterprises to provide services. One phone call and one price are mainly for reducing costs, unifying national standards, strengthening collaborative management and control of regional coordination, and making our city smoother.
Yao, a professor in the Department of Automation at Tsinghua University, said that vehicle-road coordination originated from "three drivers", namely, China problem-driven traffic, demand-driven intelligent driving and demand-driven comprehensive traffic. The core characteristics of cars and roads are perception and interaction. Taking driving safety as an example, many accidents are caused by insufficient perception. In order to realize perception and interaction, vehicle-road coordination needs the support of core technologies such as positioning, detection and communication, so as to grasp the state of each vehicle. It can be sensed by sensors such as camera, radar, microwave radar and laser radar, and interact with each other by low-delay and high-reliability communication technologies such as V2X, LTE-V(PC5) and 5G-PC5(NR). In the end, the large-scale promotion of vehicle collaboration technology will greatly change and improve the existing vehicle safety and traffic congestion, and support unmanned real road operation.
