The era of V2X technology is coming

In 2021, when autonomous driving technology is not yet ready for road use, some V2X technologies will become the focus of the implementation of intelligent connected technology.

Four automakers have already mass-produced V2X technology, mainly focusing on V2I and V2V functions

At present, there are four companies in China that have mass-produced V2X technology, including both independent brands and joint venture car companies. The joint ventures are mainly American brands, namely Buick and Ford. Other factions of joint venture brands have not yet launched related functions or plans.

In terms of function realization, it is mainly concentrated in the fields of V2I and V2V, mainly to improve driving safety and traffic efficiency. The specific functions of each company are different, among which Buick has realized more functions.

V2X technology serves autonomous driving and is currently in the LTE-V2X development stage. 2025 is an important milestone.

According to the "Intelligent Connected Vehicle Technology Roadmap 2.0", connected technology and autonomous driving technology complement each other and develop in a coordinated manner. In my country, the top-level design also plans the technical path for the development of vehicle networking technology, evolving from LTE-V2X to 5G-V2X. LTE-V2X technology mainly supports assisted driving safety and traffic efficiency improvement, while NR-V2X supports autonomous driving.

Regarding the specific implementation plan, the "Intelligent Vehicle Innovation and Development Strategy" points out that by 2025, the vehicle wireless communication network (LTE-V2X, etc.) will achieve regional coverage, and the new generation of vehicle wireless communication network (5G-V2X) will be gradually applied in some cities and highways. In terms of technical implementation, the "Intelligent Connected Vehicle Technology Roadmap 2.0" proposes to complete technical research on NR-V2X spectrum, coexistence of LTE-V2X and NR-V2X equipment, and NRUu control of LTE direct link by 2025.

That is to say, before 2025, LTE-V2X and NR-V2X will coexist.

However, from the perspective of market application, C-V2X technology will be faster than autonomous driving. The plan given in the "Intelligent Connected Vehicle Technology Roadmap 2.0" is that from 2020 to 2025, the C-V2X terminal new car assembly rate will reach 50%, and from 2026 to 2030, it will reach 100%. The application plan of autonomous driving technology is that from 2020 to 2025, the sales volume of PA and CA-level intelligent connected vehicles will account for 50% of the total vehicle sales volume in that year, and by 2026-2030, the proportion will be 70%.

It is expected that starting from 2021, the implementation and progress of various V2X technologies will be accelerated.
