V2X and vehicle-road collaboration research: 5G+V2X vehicle-road collaboration will provide strong support for highly automated driving

Zoath Automotive Research recently released the “2019-2020 V2X and Vehicle-Road Collaboration Industry Research Report”.

The V2X industry spawned by automobile networking has become an important strategic direction for developed countries or regions including the United States, Europe, and Asia. Various countries and regions have accelerated their industrial layout, formulated development plans, and passed policies, regulations, technical standards, and demonstration constructions. And other comprehensive measures to promote the industrialization process of V2X.

According to the “Smart Car Innovative Development Strategy” issued by the National Development and Reform Commission in February 2020, it is planned to achieve large-scale production of smart cars with conditional autonomous driving by 2025, and car wireless communication networks (LTE-V2X, etc.) to achieve regional coverage. The new generation of vehicle wireless communication network (5G-V2X) is gradually being applied in some cities and highways, and the high-precision time-space reference service network achieves full coverage. From 2035 to 2050, China’s standard smart car system will be fully completed and more complete.

At present, the mainstream V2X wireless communication technology in the world has two technical routes: IEEE802.11p (DSRC) and C-V2X (Cellular-V2X). The application layer standards are formulated by countries and regions based on regional application definitions.

C-V2X technology includes the current LTE-V2X technology and the 5G-V2X technology that is evolving backward. Most of the indicators of C-V2X technology are significantly better than DSRC, so it gradually surpasses behind and wins widespread support from the industry. China mainly promotes C-V2X technology.

In December 2019, the United States Federal Communications Commission (FCC) unanimously voted to pass a proposal that would redistribute most of the 5.9GHz frequency band and use these spectrums exclusively for unlicensed spectrum technology and C-V2X technology. In the past 20 years, 75MHz of the 5.9GHz band has been designated for DSRC, but the FCC is seeking to amend the rules and pointed out that the progress of DSRC has been stagnant for many years. Especially in April 2019, Toyota “suspended” the use of DSRC version of V2X communication technology, which caused a major blow to this technology.

Based on 5G NR V2X will help the development of highly autonomous vehicles

C-V2X is a communication technology based on the 3GPP global unified standards, including LTE-V2X and 5G-V2X. From the perspective of technological evolution, LTE-V2X supports smooth evolution to 5G-V2X.

The 3GPP R14 version standard supporting LTE-V2X was officially released in 2017; the 3GPP R15 version standard supporting LTE-V2X enhancement (LTE-eV2X) was officially completed in June 2018; the 3GPP R16+ version standard supporting 5G-V2X was announced on The study started in June 2018 and will form a complementary relationship with LTE-V2X/LTE-eV2X.

The design goal of LTE-V2X is mainly to support assisted driving, improve road safety, and improve efficiency and comfort; NR-V2X can better support autonomous driving and other new technologies by combining communication technology with new technologies such as artificial intelligence and big data. Features.

The establishment of the 5G NR V2X standard is progressing rapidly, and the physical layer specification is planned to be completed in March 2020.

In December 2019, among the 25 Rel-17 projects approved at the Plenary Session of 3GPP RAN in Spain, one of the standardization projects is “5G New Radio Sidelink Enhancement”, which will enhance the Rel-16 NR-V2X sidelink. In addition, the meeting also clarified the technological evolution route of the 3GPP 5G version 3 (Rel-17) that has attracted much attention from the industry. Chinese companies have led the establishment of a number of important standards for the 3GPP RAN R17 version. Leading the establishment of a number of important standard projects.

3GPP’s commercial deployment time for C-V2X (V2V/V2I)

C-V2X application process and deployment trends

The “Smart Car Innovation Development Strategy” clearly proposes to build an advanced and complete smart car infrastructure system, including (1) building smart roads and a new generation of national traffic control networks, combining 5G commercial deployment, and promoting the collaborative construction of 5G and the Internet of Vehicles; (2) Carry out research on the license for the use of dedicated spectrum for vehicle wireless communication, and rapidly promote the construction of vehicle wireless communication network; (3) Make full use of the existing Beidou satellite navigation and positioning reference station network to promote the construction of a unified national high-precision space-time reference service capacity; (4) Develop a unified smart car basic map, establish a complete geographic information system containing road network information, and provide real-time dynamic data services; (5) Make full use of existing facilities and data resources to coordinate the construction of a national smart car big data cloud control infrastructure platform .

As a key infrastructure for autonomous driving, 5G+V2X ushered in a policy outlet. Since 2019, V2X has been implemented in pilot projects. It is expected that around 2022, with the commercialization of 5G, the popularity of V2X commercialization will gradually increase, and 5G NR V2X will be tested and verified simultaneously to prepare for the large-scale application of high-level smart cars in 2025.

On the car side, the traditional T-BOX and other car terminal equipment will face changes. Automotive TCU (Tele Information Control Unit) vehicle-mounted terminals can integrate 4G/5G modules, C-V2X modules, vehicle navigation modules and other technologies and products. It is a new market opportunity for cockpit electronics and traditional car networking manufacturers, and it is also a huge challenge. Therefore, it is generally concerned by the market.

Huawei launched the C-V2X vehicle terminal T-BOX that is compatible with both 4.5G and 5G, PATEO launched the 4.5g c-v2x T-box, and Neusoft launched the T-box that integrates C-V2X/5G/Ethernet and other technologies. Box 3.0 product. The TCU launched by Samsung Harman abroad has a built-in cellular NAD and the second-generation chipset of Autotalks, providing C-V2X functions.

The development of the Internet of Vehicles has evolved from the initial TSP platform stage, to the intelligent network connection platform stage, and then to the autonomous driving cloud control platform stage (vehicle-road collaboration). As the gateway to big data for smart vehicles in the future, 5G TBOX will be the core product of automotive smart hardware manufacturers. At the same time, automakers are also cooperating with Tier1 and plan to launch 5G+v2X configurations in the next-generation models released.
