On the following day, at the Global Intelligent Car Summit of the 100-members Association, Hou Jianren, Director of Electronic Information Department of the Ministry of Industry and Information Technology, said: “The new “four modernizations†of automobiles become an inevitable trend. For the Chinese auto industry, whether it is traditional or new energy vehicles, the new system The emergence of architectures, new technology paths, and new business models is expected to enable China to get rid of the passive situation of the traditional car following path."
In fact, the reason why the development of smart cars is sought after, and the emergence of new economic forms is the main reason. At present, the national level is seeking innovation-driven, mainly to find new economic growth points. Therefore, building intelligent network-linked vehicles is still to find the economic growth point, and these growth points mainly come from the car to undergo a structural change from the hardware The proportion is large, and it turns into a larger proportion of software and services.
Li Jun, an academician of the Chinese Academy of Engineering, said: “China has analyzed the smart gridlink car. From an advantage point of view, we have a special trip scenario, a good communication base, and institutional advantages. At the same time, the country has a better strategy. It is also building a national intelligent network alliance center, but the challenges are also very serious, the technology has not been at the forefront, and the strong alliance between our OEMs has not yet begun, and foreign countries have become a new mode of operation of enterprises in this regard."
Breaking through the core technologies For automobiles to be intelligent, the key lies in designing new architectures with functions such as sensing, computing, communication, and decision making, and building an intelligent computing platform with data fusion, high-speed computing, intelligent decision-making, and collaborative control capabilities.
At the same time, the innovative applications of new generation information technologies such as artificial intelligence, 5G communication, new display, augmented reality, big data, and cloud computing will form new bearing points in automotive intelligence, new architecture, and intelligent computing platforms. Typical applications, the platform will become the basis and core of automotive intelligence.
According to Li Jun’s understanding, to develop smart cars: First, we must seize the key to development, break through core technologies, identify core technologies, digitization, sensors, and especially computing platforms; second, build the “four bases†of intelligent network-linked vehicles. That is, basic materials, basic technologies, basic components, and basic technologies. The third is to grasp scientific and technological innovations. Now many companies invest in this field, and the power of capital is very strong. However, it is necessary to prevent the core from being caught and to consume some of the capital.
From the just-concluded CES exhibition in the United States, it can be seen that the strategic layout of autonomous driving for major companies that promote automotive intelligence has become increasingly tilted toward new-style computing chips and application solutions based on computing platforms. The core tasks and priorities for the development of electronic information industry in the future.
In addition, according to the functional requirements of intelligent vehicles, Hou Jianren believes that the new architecture is based on the power, chassis, body, and electrical and electronic controls of traditional automobiles. It includes five main parts, namely, the perception of the environment, the calculation and decision-making, and the implementation of controls. Part of the network communication part and security guarantee part to realize the driving and information security of the car.
Under the new system architecture, the intelligent computing platform mainly completes the high-speed calculation and processing of multiple, massive and heterogeneous data in the process of vehicle driving and information interaction, providing real-time response to planning decisions and control, and realizing auto-driving and networking services. Intelligent computing platforms, which are composed of computing chips, sensor control, communication networks, operating systems, and artificial intelligence algorithms, will play an increasingly important role and become the core and commanding point of the industrial ecology.
To build an industrial ecology However, mastering only the core technologies can not meet the needs, and it must have our own characteristics and satisfy all needs. For example, in the past, if people were to get a car, they were all looking for a car. They needed to stop a taxi on the road, and later they set up a car. Now, you can go to the parking lot to find a shared car, but in fact, these are not intelligent, only to find people to find a car, car to find people, find a car, to achieve the entire process of intelligence is the real smart car.
These car prices alone cannot be achieved and need to be promoted at the national level. In this regard, Li Jun said: "Our country's scientific and technological innovation should be tilted to the above aspects, at least to achieve the new energy vehicle's tilt. At the same time, to create a new innovation platform, but what is the innovation platform, the current Ministry of Industry and Information Technology in the creation of national intelligent network The United Automotive Innovation Center, the Ministry of Science and Technology, the National Development and Reform Commission, and the Ministry of Education are also building. The entire country’s innovation platform is in what form, and it is also necessary for us to explore."
At the same time, he stressed: “Intelligent grid-linked vehicles are typical asset-light development models. Cross-border integration is one of the most important features. The degree of cross-border growth is also to be enhanced. It is necessary to cross-industry with other industries, such as the ITS industry and the ICT industry. In addition, we must plough the city, because the market is in the city, and the application scenario is also in the city, so as to promote the deep integration of smart cities, intelligent transportation and smart cars."
From this point of view, cross-border integration is the basic feature of the entire intelligent transportation system. It requires the cooperation of multiple industries such as the automobile manufacturing industry, transportation industry, communications industry, IT industry, and operation service industry. There are requirements for road safety, traffic efficiency, and entertainment services.
The communication system provides information services for automobiles. The first is the improvement of transportation efficiency. The information and entertainment services have important help. The second is V2X, vehicles and vehicles, vehicles and infrastructure, vehicles and people. V2X stands for all vehicles and other things. The way of communication.
In fact, in September 2016, 5GAA was established internationally. This alliance combines car manufacturers, telecom operators, and telecom equipment manufacturers with more than 40 companies. In the past, car networking had 802.11P and C-V2X. It was a system of traditional cellular networks and formed the standardization of V2X, also called C-V2X. Therefore, the establishment of the 5GAA alliance has enabled so many car manufacturers, manufacturers, telecom operators, and telecom equipment vendors to support the C-V2X industry. At the same time, Qualcomm and Ford have also conducted C-V2X tests.
The V2X communication standard has always existed two major support camps: First, the DSRC program dominated by the United States, Europe, and other countries. At present, most enterprises adopt this communication standard; the second is the LTE-V program, which is made by domestic Datang Telecom and Huawei's leading communications program. Therefore, the communication system faces the choice of the technology path.
In response, Wang Min, chief engineer and chief scientist of Datang Telecom Technology Industry Group, said: "802.11P has been released for many years and has undergone a lot of tests, but the LTE-V standard is a new standard, and the new standard is With advanced technology and adaptability to the development needs of the modern automotive industry, more tests and more experiments are needed in the domestic demonstration area, while the LTE-V combines the existing cellular network infrastructure and can be used as an intelligent network for automobiles. Lianhua provides more comprehensive services, however, does this network need to have a corresponding operator, what kind of company can take on the role of operators, what kind of services are provided, what kind of business model, and what is the charging model? It will require the collaboration of various industries and will require more guidance and assistance from the government."
The core of smart cars lies in information exchange: computing platforms will seize the commanding heights
“The future of automobiles is bound to be an era driven by intelligence and pure electric power. The most suitable vehicle for intelligentization is new energy vehicles. After clearing a new direction, vehicle products must work hard in terms of comprehensive performance, so it is necessary to increase energy storage. Specific energy, intelligent control, etc.†On January 20th, Minister of Science and Technology Wan Gang expressed at the China Electric Vehicles Centenary Forum.
