"The development direction of a new generation of smart cars is the combination of autonomous driving and connected cars. At present, auto companies are also making autonomous driving products, and these products are still separate: assisted driving is assisted driving, Internet of Vehicles. It is the Internet of Vehicles, and the combination of the two is an opportunity and challenge for all automotive companies, including emerging companies. "At the Second Global Smart Car Frontier Summit held recently, a professor at Tsinghua University and the State Key Laboratory of Automotive Safety and Energy Conservation Director Li Keqiang put forward his views in an interview with a reporter from China Automobile News.
New features of intelligent network
Recently, the popularity of intelligent connected cars has soared and entered a period of rapid development around the world. It is not important whether the direction of intelligent cars in the future is 100% autonomous driving or highly automated driving. However, on existing vehicles, through a new generation of mobile Internet Technology, making it well-connected based automation, this must be a development trend, is still in the ascendant in the world, the main body of research may not only be traditional cars, but also not only auto companies among the participants, There are also Internet companies, communications companies, and cross-border integration of the enterprise ecosystem, which may be a good development model.
Li Keqiang believes that whether it is autonomous driving or intelligent connected cars, in the true sense of autonomous driving under various working conditions and conditions, it should be said that there is still a long way to go, and there is still a long way to go. For highly automated driving, if you can talk about some specific scenarios, such as valet parking and other specific areas and specific scenarios, it is still a competitive point for mass production of cars.
Intelligent connected cars are a new product form, new business model, and new ecology. In the new round, based on a new generation of mobile Internet technologies, including big data, cloud, and AI, they have entered this field. The development model has a big impact. It should be emphasized that the safety issues of automotive products, including the various functional safety issues and information security issues mentioned, are also issues that need to be focused on for development.
As Intelligent Connected Vehicles are new products, new models, and new formats, it is an inevitable trend to truly promote the industrialization of this product in the real sense of industry cooperation and cross-border collaboration. Li Keqiang said that according to the current development trend, there is a relatively successful project in Japan's national project-the dynamic basic map platform, which fully separates the application layer and the basic layer. The basic layer requires industrialization in a coordinated manner.
Autonomous Driving China Solution
Looking at China from the perspective of international developments, there are some new features and new requirements for the development of intelligent connected cars. In the era of autonomous driving, especially in the era of intelligence, local attribute requirements are more intense. In other words, future autonomous driving products must have autonomous driving products under the working conditions of each country. It can be considered that there will be both self-driving products with Japanese local attributes, and of course there will be self-driving products with local attributes in China. Therefore, we chose a product called "Automated Driving with Chinese Plan" for products adapted to local attributes in China.
Li Keqiang's explanation is that, first, autonomous driving plus "network-connected", first of all, we must adapt to China's infrastructure, including China's road infrastructure, information infrastructure, China's map, positioning, communication, these are completely local attributes . The second is that if future autonomous driving is to be networked, there must be a networked operating platform. This platform must be in China, where there is a standard for Chinese networked operations. Future automotive products and product architecture will change. At least the current electrical and electronic architecture will change, and the electrical and electronic architecture of the car will change. Of course, it is a new standard vehicle. In the future, special emphasis will be placed on electrical and electronic, including on-board architecture of information.
Therefore, around these futures, which are local attribute standards and local attribute schemes, there will naturally be autonomous driving for Chinese schemes. In the future, if you want to adopt a networked approach, the vehicle is running on an intelligent infrastructure and has an operating platform to meet information security. This new product form will change from product architecture to operations to future value-added models.
"In the future, China will really promote autonomous driving, and the product form will change. There are five basic platforms in this product form." Li Keqiang said, including cloud control basic platform, high-precision dynamic map basic platform, vehicle terminal basic platform, computing Basic platform, information security basic platform. These five platforms are new parts and new key and important components after the new generation of automotive products enter the era of intelligent networking. The key components of traditional cars are the engine, power system, drive system, control system, braking system, and driving system. In the era of intelligent networking, there are these five technology platforms on the system. These five technology platforms are basic components and products. How to develop, produce, and use this product is a complete function that we must think about and must promote when promoting the industrialization of autonomous driving.
In the future, any platform for autonomous driving, car-to-car connection, car-to-people connection, car-to-cloud connection, is a basic platform itself, not the current product, it must be a changed product, and this changed product can only rely on one family. It is collaborative.
Under such circumstances, the product shape of the infrastructure will affect the industry chain after connection. The traditional industrial form-second-tier suppliers, first-tier suppliers, and then to the OEM. In the era of intelligent networking, it is assumed that there are three large blocks in the middle of the development of the controller. It is necessary to negotiate with information and communication, to discuss cooperation and collaboration. It is not a family that can dominate. It can only be achieved by data interaction. .
Information security deserves attention
Because of the Internet of Vehicles in autonomous driving, there will naturally be network information security issues. In autonomous driving, including high-precision maps, all rely on network communication.
Among them, the vehicle can be connected to the cloud through real-time communication, and a series of analysis and judgment can be made through the cloud, and finally the physical end can be interfered. Including the information security basic platform and the vehicle terminal platform, we can use this kind of positioning and such a collaborative development model to promote effective and reasonable market-oriented competition in this society. "The five basic platforms will form a new development model for the industry in the future, which is based on the national development strategy and the major needs of the industry, supported by the needs of real enterprises and used by real enterprises to complete the re-synergy of these five platforms. "" Li Keqiang believes.
The five basic platforms involve strategic infrastructure, which has both social attributes and market-oriented competition support. For R & D, industrialization, and application, consensus needs to be gathered and top-level design required. Of course, such platform development requires gathering resources, integrating innovation, and cross-border personnel to form and operate such a company. "When such companies develop products, they also need market-driven and coordinated development. Of course, they are complex systems, they need to be modeled and applied, and they need to build a whole social ecology. Only in this way can industrialization be truly formed."
