5G promotes the future of autonomous driving

June 18, 2019
(This website Wuhan news): 5G arrival, how to use in the car, a few days ago, Jun Feng Automobile Company technical person Xiao Bing and related experts received an exclusive interview with this network.

Before the 5G commercial presses the fast forward button, the three major operators in China have completed 5G technology-related infield and outfield tests in pilot cities such as Beijing, Shanghai, Hangzhou, Shenzhen and Guangzhou, and in health care, education, and urban management. And other areas to try 5G application solutions.

Among them, the industry is most concerned about the 5G application scenario of the Internet of Vehicles. Regardless of whether it can become a "killer application" for 5G, major telecom operators, communication vendors represented by Huawei, ZTE, and Qualcomm, or Internet giants, have long been in the field of car networking. Pan Feng, deputy director of the Radio Research Center of China Information and Communication Research Institute, analyzed China News Weekly. The integration and innovation of 5G and Internet of Vehicles not only helps China to seize the strategic commanding heights of the development of the Internet of Vehicles, but also helps accelerate the 5G in China. Innovative deployment applications.

What application scenarios can the car network achieve? What is the promotion of the 5G license to the Internet of Vehicles? Many industry insiders believe that the launch of 5G commercial licenses is a stimulus to the industry, which can accelerate the development of key areas such as chips and resource concentration. However, the application scenarios of car networking and auto-driving under 5G technology really landed. Policy support, infrastructure construction and many other aspects of synergy."

Xiao always described the following scenario to us:

“The vehicle is driving on the road. The push and reminder of the traffic light signal in front is synchronized with the center console in the vehicle. The vehicle can know the abnormal conditions such as road construction and wet skiing ahead of time, reminding the driver to adjust the driving route; the vehicle is getting crossed. Pedestrian information on the road reminds the driver to avoid it in time..."

“In the Fengfeng guided driving project, V2X is mainly realized by obtaining information from the government cloud platform through the 4G network and direct information interaction between the car and the car through point-to-point.”

C-V2X (Cellular Vehicle-to-Everything) has become the focus of automotive networking technology for automotive companies, communications industry chain companies and telecom operators. In short, C-V2X is based on cellular technology, which connects cars to everything, including cars and cars (V2V), cars and networks (V2N), cars and infrastructure (V2I), cars and pedestrians (V2P). ) Four types of scenes.

“The current stage of C-V2X development is mainly based on the evolution of LTE mobile communication technology to form LTE-V2X/LTE-eV2X technology, which can be used to meet the needs of automotive active safety warning and traffic efficiency improvement services.”

What is the actual promotion of 5G for the Internet of Vehicles? It can be seen from a set of data comparison: the self-driving car runs at a speed of 60 kilometers per hour. If the time delay is 60 milliseconds, the braking distance of the car is about 1 meter; if it is a delay of 10 milliseconds, the braking of the car The distance is 17 cm; if the theoretical delay of 5 G is reduced to 1 msec, the braking distance is shortened to only 17 mm.

Low-latency, high-bandwidth, high-stability and other 5G features enhance vehicle perception, decision-making, and execution capabilities, and provide a good foundation for vehicle networking and autonomous driving applications, especially for applications involving vehicle safety control. . “High-level auto-driving functions involving low-latency, high-reliability vehicle control, such as formation driving, remote control, etc.; and applications requiring large bandwidth, such as high-precision map downloading, video backhaul, etc.” Tsinghua University Dai Yifan, director of the Intelligent Networking Automotive Center of Suzhou Automotive Research Institute, told reporters.

The 5G commercial timetable is ahead of schedule, and the innovation of the vehicle networking industry is becoming increasingly active, facing a broad market development prospect. According to the China Society of Automotive Engineering, the ratio of sales of new car networks in China will reach 80% and 100% respectively in 2025 and 2030, and the total market size will exceed one trillion yuan. According to Accenture, an international consulting firm, the size of the Chinese car networking market will account for a quarter of the global market in 2025.

"The biggest market for mobile IoT may be the Internet of Vehicles. The application of 5G technology represented by driverless cars may be the earliest application." Miao Wei, Minister of Industry and Information Technology, said at the "2019 Boao Forum for Asia". The Ministry of Industry and Information Technology is studying the development of vehicle networking, and will work with the Ministry of Communications to accelerate the digitalization and intelligent transformation of highways.

Previously, in December 2018, the Ministry of Industry and Information Technology issued the "Car Network (Intelligent Networked Vehicles) Industry Development Action Plan" (hereinafter referred to as "the "Action Plan"), proposed the intelligent networked car large-scale commercial time point - 2020 In the future, the intelligent networked car with high-level autopilot function and 5G-V2X will gradually realize large-scale commercial applications. The "Action Plan" also stated that by 2020, the cross-industry integration of the car networking industry will achieve breakthroughs. Intelligent networked cars with high-level auto-driving functions will achieve specific scene scale applications, and the penetration rate of car networking will reach more than 30%.

How to achieve --- synergy and ecology?

"5G needs cross-industry application innovation, jointly explore the multi-party win-win 5G business model, and strengthen the 'cloud-pipe-edge-end' collaborative deployment for 5G applications." Xiao and all experts believe that due to 5G technology changes, products The maturity is high. In the early days of commercialization, operators and equipment manufacturers have completely solved the problems of network planning, networking, operation and maintenance, etc., and the compatibility between 5G terminals and networks needs to be gradually implemented in the commercial process. Optimized and perfected.

In fact, the three major operators in China have already deployed the car networking business ten years ago. They intend to dominate the development of the car networking industry. In 2018, they will independently establish their car business and set up a car network or IoT subsidiary to develop a car network. Business and automotive cooperation. In 2018, China Mobile integrated the establishment of the car networking company - Zhongzhi Zhixing Network Technology Co., Ltd. (hereinafter referred to as "Zhongzhi Zhixing"). In April of this year, China Unicom's car networking subsidiary Unicom Zhiwang Technology Co., Ltd. introduced 9 strategic investors, including many traditional car companies such as FAW, Dongfeng Motor and Guangzhou Automobile.

At the same time, Huawei and other communications equipment vendors have accelerated penetration in the field of car networking. Huawei, which was rumored to be “making a car”, officially upgraded its auto business on May 27 and set up a smart car solution BU, ranking first-level. "Car networking, artificial intelligence, and edge computing are the three breakthroughs for Huawei's future." Ren Zhengfei previously said that Huawei's car networking can set up commercial organizations and increase strategic investment in autonomous driving.

In terms of Huawei, the three supporting business operators BG, enterprise BG and consumer BG are relatively mature, and the automotive sector is a new business opportunity. As early as 2013, Huawei established the car networking business department. In the same year, the car module ME909T was launched, and the car communication was deeply deployed in the field of car networking and automatic driving.

Different from Huawei, BAT and other Internet giants are basically entering the Internet with the software system as the entry point, positioning the Internet as a "total solution". For example, Tencent and Baidu respectively passed the "AI IN CAR car system" and "small car The OS system" entered the automotive field.

Since the beginning of 2019, the Internet giant has been active in the field of car networking. On January 27th, Baidu officially released CarLife, a cross-platform car networking solution. This is the second major move of Baidu's entry into the Internet of Vehicles following the release of CarNet during the Beijing Auto Show last year. Previously, Baidu announced the “Apollo” program in 2017, announcing the opening of an autonomous driving platform, which became the largest Internet company in the wave of automatic driving.

Tencent, a relatively low-key in the field of car networking, officially released the "Eco-Car Networking" solution on May 22. The Tencent Department and third-party content services are ecologically integrated into the car to get through the car, in the car, and after the car experience; based on the AI scene, realize the intelligent scene-driven "Thousands of people + service to find people."

Ali also continues to work in the field of car networking. On May 26, Alibaba Cloud Computing Co., Ltd. and Qianfang Technology signed the Cooperation Framework Agreement. At the same time, Alibaba.com acquired 223 million shares of Qianfang Technology for RMB 3.6 billion, and held a 15% stake in Qianfang Technology, becoming the company's second largest shareholder.

With the improvement of industry maturity, the connection between car networking and car safety and big data has received much attention. Data ownership is also considered to be the core asset of car companies. Liu Gang, deputy secretary-general of China Automotive Network Industry Technology Innovation Strategy Alliance, told China News Weekly, “Many vehicle manufacturers will choose to establish their own platforms and establish them in order to ensure their own data security and achieve future leadership in the field of automatic driving. Subsidiaries or looking for external deep strategic cooperation to complete digital transformation, such as Zebra Zhixing, Xiongzhi Zhiyun, Wutong Chelian, and Wenzhong Intelligence."

Our vision---the future of autonomous driving

Every time the communication technology is iterated, the higher network speed is the focus of the upgrade, and the speed increase will be applied to many vertical industries. 5G defines three business scenarios: eMBB (Enhanced Mobile Broadband), mMTC (Massive Machine Communication), and uRLLC (Super Reliable Low Latency Communication).

Specifically, eMBB is mainly for high-traffic mobile broadband services such as 3D/Ultra HD video, which is equivalent to the enhancement of 4G network. The user experience rate is 0.1~1gpbs, and the peak rate is 10gbps. The mMTC scene corresponds to the Internet of Things and other connections. The application, according to relevant standards, can support 1 million devices per square kilometer; while uRLLC is ultra-reliable and low-latency (less than 1ms) is suitable for auto-driving, industrial automation and other scenarios.

For the construction and deployment architecture of 5G networks, 3GPP defines two standard options: non-independent networking (NSA) and independent networking (SA). The primary task of promoting 5G commercial is to choose the networking mode.

Looking forward to the future, Junfeng Motor Corporation has done a lot of work in smart car technology development and technology reserve. The intelligent operation based on 5G technology will be fully launched, and a great era of smart cars will be opened.
