In 2020, "new infrastructure" has become the focus of attention. According to statistics, as of March 1, 13 provinces and cities across the country released a list of key project investment plans for 2020, involving a total investment of about 34 trillion yuan in new infrastructure. Seven major sectors, including 5G infrastructure, charging piles, big data centers, artificial intelligence, industrial Internet, etc., covering all aspects of transportation and travel, industrial production, livelihood protection, communications and so on.
Seven major areas of new infrastructure
Autonomous driving into the fast lane
Compared with the traditional "iron and public infrastructure", "new infrastructure" with a strong industrial Internet gene, emphasizing the use of many already existing cutting-edge technology, It emphasizes the use of many existing cutting-edge technologies and techniques to transform and upgrade traditional industries, and is a "merging" development process. From this point of view, the technology accumulation of many Chinese technology enterprises over the years has laid the foundation for the development of the "new infrastructure".
Taking the? Artificial Intelligence (AI), one of the seven major sectors of the "new infrastructure", for example, can be considered the crown of AI technology, as autonomous driving integrates almost all types of AI technology. Its development and application involves a variety of aspects from the underlying hardware to AI technology and platforms, including chips, sensors, computer vision, cloud platforms, big data services and other technology segments, covering environment perception, decision-making, high-precision maps and localization, vehicle networking V2X, decision-making and control, testing and validation and other complex subdivisions of the industry chain.
Tencent self-driving car road test
Every industrial revolution is driven from the three major fields of energy, transportation and information. With the country's strong support for the development of the new energy industry, the popularization of 5G communication networks with large bandwidth and low latency, and the construction of intelligent roads, autonomous driving will enter the fast lane of development.
Technology companies to increase technical investment in the field of automated driving
In the past few years, in order to realize the commercialization of automated driving, Tencent as the representative of a large number of science and technology companies invested a large amount of resources, for automated driving to meet the "new infrastructure" era has been a sufficient reserve of technical capital.
1, high-precision maps covering the country's highways and expressways
Taking high-precision maps as an example, it can provide vehicles with accurate vehicle location information and rich road element data information, and help the car anticipate the complex information on the road surface, such as gradient, curvature, heading, etc. For self-driving cars above the L4 level, high-precision maps are a necessary condition.
China has only a handful of enterprises with high-precision map production qualifications, and Tencent is one of them. At present, Tencent's high-precision map team has completed the collection of high-precision maps and data production for expressways and highways in key cities across the country, and L4-level self-driving cars based on high-precision maps have also begun road tests.
2, automatic driving simulation technology landing application
Testing and verification, is a major difficulty in the landing of automatic driving technology. Absolute safety is human expectations and requirements for self-driving cars, and the industry generally believes that to do this, at least 11 billion miles of test data is needed to optimize the self-driving system. That would require 100 cars, running around the clock at 40km/h for more than 500 years, an unreachable goal for any company.
In order to accumulate enough test data, using simulation platforms to improve testing efficiency has become a common choice in the industry. Tencent has also utilized its powerful game engine, industrial-grade vehicle dynamics model, 3D reconstruction and other technologies to create TAD?Sim, an automatic driving simulation system.

By means of high-precision and scalable simulation technology, Tencent's automatic driving simulation platform can build a scenario infinitely close to the real world based on specific needs, which can not only meet the needs of continuous iteration, but also provide the best possible solution for the industry. In addition to scenario-based cloud simulation, Tencent has also built virtual city-based cloud simulation, which allows self-driving vehicles to run continuously in a virtual environment and supports massively parallel acceleration to improve testing efficiency and meet the validation needs for the development of self-driving technology.
At present, the National Intelligent Networked Vehicle "Changsha" Test Center and other automatic driving test and verification organizations are also adopting Tencent's simulation platform to explore innovative applications for test and verification.
3. Conform to the times? Layout 5G-V2X
V2X is another key technology for autonomous driving to land, in which V stands for vehicle and X stands for any object that interacts with the vehicle's information, and the current X mainly contains vehicles, people, traffic roadside infrastructure and networks. The role of this technology is to open the vehicle, road, people's closed loop, real-time information interaction between the vehicle and the outside world, in order to maximize to make up for the lack of single-vehicle intelligence, to ensure that the self-driving car in the extremely complex traffic environment can also be safe driving.
V2X technology needs to rely on 5G to bring large broadband, low-latency information interaction. In the "new infrastructure", the construction of 5G has also been given top priority as the key to supporting the digital, networked and intelligent transformation of the economy and society.
In terms of the use of 5G-V2X, Tencent's Future Network Lab officially released the 5G Vehicle-Road Collaboration open-source platform in May 2019, focusing on the field of vehicle-road collaboration based on edge computing, and focusing on solving the industry's pain points such as low penetration rate of terminal equipment, lack of mainstream software to reach the user, lack of effective connectivity of road equipment, and fragmentation of road information, so as to promote the rapid landing of intelligent networked vehicle applications. The rapid landing of the intelligent networked car application.
Conclusion:
On the one hand, the new infrastructure boom has brought more development opportunities to technology enterprises, on the other hand, the innovative exploration of technology enterprises has also provided the basis for the new infrastructure power. It can be said that Tencent as the representative of the technology enterprises, reserves a large number of cutting-edge technology, in the "new infrastructure" to promote, popularize, can help players in the automatic driving industry to achieve rapid development, and promote the construction of intelligent transportation system.
In the future, along with the comprehensive rollout of the "new infrastructure", the upstream and downstream of the autonomous driving industry chain will usher in more room for development, and such a virtuous cycle is of great significance to the construction of the intelligent transportation system represented by the autonomous driving technology and even the overall development of the whole society.
