5G new infrastructure acceleration, how to pave the way to the landing of vehicle-circuit cooperation? The expert big shot said this!

Where is the new wind direction of vehicle networking technology and industry under the background of 5G? How to innovate intelligent transportation and help vehicle-road synergy? Vehicle networking pilot area application scenarios how to build?December 3, held in Chongqing, the fifth i-VISTA intelligent networked vehicles international symposium, come from the Institute of Communications, Tsinghua University, China Telecom, Datang Mobile, China Automobile Academy and other experts, around the "5G new infrastructure and vehicle road synergy", to bring high-energy point of view of the collision and technology sharing.

Ge Yuming, deputy director of the China Academy of Information and Communications Research, shared that 5G has entered a stage of large-scale development, and only three operators have opened more than 600,000 5G base stations, with more than 15,000 new construction every week. 2025 China's total investment in 5G will reach 1.5 trillion. Vehicle networking is the empowerment of 5G, AI and other new generation technologies in the traditional industry, 5G communication technology to vehicle application scenarios to bring more imagination. For example, the maturity of LTE-V2X technology can support the realization of some low-latency, high-reliability safety warning applications. For example, intersection collision warning, front and rear vehicle brake warning, etc.; the concept of intelligent cockpit; the realization of some automatic driving functions and so on.

In his view, in the face of the challenges faced by the current scale of commercialization of Telematics, not only lies in the technology, but also to build a new convergence of industrial ecology. In the future, for the cooperative stage, based on 5G to build a person, vehicle, road, cloud can be highly coupled interconnected environment, realize the vehicle and road cooperative control, vehicle-vehicle cooperative formation, remote operation and other advanced/completely automated driving business, and ultimately support the realization of fully automated driving.

Zhao Xinyong, general manager of Huaru Yi Yun Technology Co., Ltd, said that the development of Telematics brings new opportunities for intelligent transportation. Intelligent transportation in the future vehicle road system is broadly divided into two categories, one is urban transportation, the other is intelligent highway. How will the future development of intelligent transportation? Zhao Xinyong to "a city all the way, there is a core and a soul, cloud network cloud services, a price" briefly summarized. Specifically, first of all, is to realize the interconnection of transportation infrastructure, real-time perception of traffic data, data **** enjoy. Secondly, the improvement of intelligent transportation products, chip and cloud will be the main development trend of the future intelligent transportation system, to build the software architecture for urban transportation and highway management. In addition, the cloud network cloud service is mainly to unite large enterprises to establish a monitoring library, query library, and a pre-proposal library to provide services. One pass, one price is mainly to reduce costs, the implementation of the national standardization, strengthen the regional coordination of collaborative control, so as to make our city more smooth.

Yao Danya, a professor at Tsinghua University's Department of Automation, said the origin of vehicle-road coordination is "three drives", namely, China's traffic problem drive, intelligent driving demand drive, integrated transportation demand drive. Vehicle and road, its core features are perception and interaction. Taking driving safety as an example, many accidents are caused by insufficient perception. To realize perception and interaction, vehicle-road collaboration requires the support of core technologies such as positioning, detection, and communication in order to grasp the state of each vehicle, perceive it through sensors such as cameras, radar, microwave radar, and lidar, and interact with it through low-latency and highly reliable communication technologies including V2X, LTE-V (PC5), and 5G-PC5 (NR). Eventually, vehicle collaboration technology to carry out large-scale promotion, will significantly change and improve the existing vehicle safety and traffic congestion state, to support the real driverless on-road operation.
