How to turn on smart cars in the first year of 5G commercialization?

As a new generation of information technology, the most prominent features of 5G are large bandwidth, low latency and wide connections-it can achieve data rate as high as 10Gbit/s, delay as low as 1 millisecond and connections per square kilometer 1 10,000. Relying on these characteristics, 5G has been endowed with the mission of connecting everything and empowering all walks of life since its birth. Especially in the automotive field, 5G has always been considered by the industry as a key technology to promote the accelerated landing of autonomous driving and car networking.

2065438+On June 6, 2009, the Ministry of Industry and Information Technology officially issued 5G commercial licenses to China Telecom, China Mobile, China Unicom and China Radio and Television, and China's 5G commercial journey officially started. So what does the arrival of the 5G era mean for the automobile industry? How will 5G technology subvert the automobile and even the entire travel industry in the future?

"As the fifth generation of mobile communication, 5G will bring revolutionary changes to the automotive industry and accelerate the development of autonomous driving, in-vehicle entertainment and navigation systems. In terms of vehicle networking, with the help of 5G technology, it is also possible to break the limitations of the vehicle's own sensors, share data with other vehicles, roads and infrastructure, and generate predictive information through research and judgment, thus helping the autonomous driving technology to be more mature and perfect. " A few days ago, it was jointly sponsored by Volvo and Global Automobile Group. "Redefine the gene of 5G car networking", Shi Jianhua, deputy secretary general of China Automobile Industry Association, said at the 2020 China Smart Car Summit Forum. For example, in automatic overtaking, cooperative collision avoidance, vehicle formation and other scenes, due to the high requirements for reliability and time delay, it is inseparable from the support of 5G.

On the supply side, the application of 5G technology is expected to accelerate the transformation and upgrading of the traditional automobile industry to the smart automobile industry. At present, major domestic car companies have started their own 5G pace. From smart city to intelligent transportation, and then to intelligent cockpit, China car companies have already laid out in advance.

"5G will bring great changes to the form of the automobile industry, help the automobile industry to achieve true intelligence and enter the fast lane of autonomous driving. What 5G brings us is not only the change of product form, but also the change of business ecological environment. Just like the emergence of smart phones, it has brought about changes in the ecology, life and environment of the whole human society. After the car is connected by 5G, this analogy can also be made. It is no longer just a means of transportation, but a huge social change. "

Shi Jianhua also pointed out that although 5G can make cars smarter, the problems it faces cannot be ignored. For example, 5G technology has not been commercialized, and the research and development level is relatively weak, so the future vehicle operation should be guaranteed. "Therefore, China automobile enterprises must face up to difficulties, plan strategies, strengthen exchanges and cooperation with technology companies and the telecommunications industry, take challenges as opportunities, and form new competitiveness. In the end, when the 5G era comes, there will be many new business ecological models in the automobile industry. Whoever can grasp it is likely to gain huge business opportunities. "

Justin, executive deputy general manager of Shanghai Intelligent Networked Automobile Technology Center Co., Ltd. believes that with the help of 5G, the brand-new intelligent networked automobile, garage, travel service, intelligent transportation and information security are all combined, which may form a scale of 2 trillion, which is equivalent to rebuilding a Pudong.

Among them, in the intelligent networked automobile industry, Hongyuan believes that there are two routes that can be commercialized quickly: low-speed complex scenes, such as AVP, high-speed simple scenes, such as traffic jam-assisted TJP and high-speed automatic driving HWP. If we want to pursue both high speed and complex scenes, it will take time. There is a big problem here, which is cost. China is a low-cost country, and consumers are extremely sensitive to prices. If consumers refuse to pay the bill, it will be difficult to achieve commercialization.

Lu Xiaofeng, general manager of Huawei's V2X product line, said that the changes brought by 5G and V2X to intelligent networked vehicles are mainly reflected in three aspects: First, experience enhancement. Through 5G technology, users can experience video, music, information and mobile office. Improve. Second, improve travel efficiency. The organic combination of V2X and 5G network can realize high-precision map dynamic update, remote maintenance, software upgrade, emergency call, navigation and other applications, which greatly improves people's travel efficiency. Thirdly, to improve driving safety, based on the interconnection between vehicles and road infrastructure, not only the potential dangers and special situations on the road, or the information that cannot be obtained in real time by traffic management platform, current Internet map and on-board sensors can be transmitted to vehicles as soon as possible, so as to realize the auxiliary driving functions such as collision avoidance, lane diversion and road information notification, but also the advanced automatic driving functions such as automatic formation, cooperative driving and remote driving. Especially the third point is particularly important. According to relevant statistics, if the driver can know the emergency on the road 2 seconds in advance when driving, it is possible to avoid more than 95% traffic accidents.

Yuan Xiaolin, global senior vice president of Volvo Car Group and president and CEO of Volvo Car Asia Pacific, also believes that the development of V2X road collaboration technology based on 5G will accelerate the further landing of smart cars and bring more possibilities for future travel. In his view, the combination of 5G and V2X technologies can truly realize the coordination of people, vehicles and roads and the real-time enjoyment of information, thus creating a more efficient, safer and more environmentally friendly intelligent transportation environment.

However, Yuan Xiaolin also pointed out that future travel is a huge ecology, and it is never possible to solve the problem alone, and open cooperation can maximize the value. In particular, the development of V2X vehicle-road collaborative technology requires partners in various fields to rely on public infrastructure and urban smart transportation resources to achieve effective cooperation and form a joint force, so that the accumulated experience of all parties can give full play. Only in this way can we achieve common development and make science and technology better serve travel and human beings.

Based on this, during this forum, Volvo and China Unicom formally signed a 5G strategic cooperation agreement. According to Liang Baojun, deputy general manager of China Unicom, in order to better help the arrival of the 5G era, China Unicom is accelerating the construction of 5G network infrastructure and actively carrying out extensive and in-depth cooperation with vertical industries. "We established the China Unicom 5G Innovation and Application Alliance. At present, there are nearly 1 0,000 members, which is to build a platform for innovation and joint innovation. " Liang Baojun said.

Among them, in the automotive field, China Unicom established its subsidiary Unicom Wang Zhi Technology on 20 15, which is fully responsible for the automotive information service of China Unicom. Up to now, it is reported that China Unicom has reached cooperation with more than 80 domestic and foreign car companies, serving more than 60 million networked cars. Moreover, China Unicom has also conducted in-depth research in the fields of V2X vehicle-road coordination, 5G remote assisted driving, automatic driving and intelligent transportation, and carried out 5G intelligent network connection and intelligent transportation application demonstration projects in several cities.

According to the agreement, the two sides will set up a 5G joint laboratory, based on the next generation mobile network technology of 5G, * * to promote the development of China V2X vehicle-road collaborative technology, * * * to research, develop and test the application of 5G and emerging V2X technologies in automobiles, thus helping China's automobile industry to achieve leap-forward development in the field of smart cars and become a global leader in smart cars.

It is worth mentioning that this is not the first cooperation between Volvo and China Unicom. As early as 20 13, the two companies have already carried out very close cooperation in the field of car networking, such as car networking driving, integrated communication, service operation and so on. On 20 19, China Unicom and Volvo jointly launched an automatic parking service project based on the 5G-V2X vehicle-road collaboration technology. In the pre-research project, 5G and V2X communication devices are added to the existing Volvo production vehicles, and existing sensing devices such as V2N (vehicle-to-cloud), V2I (vehicle-to-vehicle infrastructure) and V2V (vehicle-to-vehicle) are integrated to realize the unmanned parking service in specific scenes (test sites).

In the future, Yuan Xiaolin said that Volvo will continue to join hands with China Unicom and other partners to look forward to innovation and jointly promote the development of this smart car.
