Vehicle-to-everything (V2X)

Qualcomm, Hyundai Motor Company, BYD Company, Nissan Motor Co., LG Corp and Samsung are among the companies active in V2X. Qualcomm develops cellular and wireless technologies relevant to connected vehicles, including 5G NR-V2X capabilities. The company list also includes automotive manufacturers, electronics firms and suppliers working across vehicle communication and connectivity.

AUTOCRYPT is a V2X startup to watch, with 14 documents in the 24-month window and an 80% increase in activity. Its stated focus is mobility cybersecurity, including defenses and security services for V2X systems. Those capabilities address a persistent need as connected vehicles exchange safety and operational data across open networks.

Southeast University is a prominent research organization, with 209 documents in the 24-month window. Its researchers study V2V authentication, federated learning in vehicular networks and packet management for timely V2X updates. Xidian University is another active group, with work on V2X cooperation, secure authentication and cooperative vehicle-infrastructure perception.

V2X-related grant data records $230.9 million across 188 grants since 2020. This figure refers to grants in the dataset and should not be read as a complete measure of all commercial investment in V2X. Funding-round data also records $63.48 billion in aggregate rounds, but those rounds are not necessarily dedicated to V2X development.

BYD Company leads the listed V2X patent holders with 207 patents. Hyundai Motor Company follows with 113, and Nissan Motor Co. has 107. Other listed holders include Shenzhen Yinwang Intelligent Technologies Co., Ltd., Huawei, Qualcomm and Geely, showing activity across automakers and communications technology companies.

V2X patent activity declined 34.5% in the latest 12-month period compared with the previous 12 months. The 24-month patent window contains 4,660 patents. These figures indicate a recent slowdown in patenting, but do not by themselves show whether deployment, investment or technical progress is also slowing.

Recent work includes authentication, privacy protection, beam tracking and satellite-vehicular networking. In September 2026, Zhengzhou University of Light Industry published work on lightweight authentication, while Nanyang Normal University examined privacy-preserving batch authentication. In August 2026, Tokyo University of Science and Kozo Keikaku Engineering Inc. proposed O-RAN-based beam tracking for mmWave V2I.

The main approaches are DSRC and ITS-G5, LTE C-V2X, 5G NR-V2X, network-assisted cellular and hybrid multi-radio. DSRC and ITS-G5 provide direct short-range communication, while cellular approaches can add network assistance and broader-area connectivity. Hybrid multi-radio combines technologies, but increases integration and coordination demands.

The United States leads the country data with 49,025 documents, followed by China with 25,863 and Japan with 21,368. Germany has 18,891 documents, and India has 13,536. These figures indicate where V2X-related documents are associated; they do not measure deployment or market share.

V2X applications include fleet and transit operations, traffic operations, cooperative and automated driving, road safety and vulnerable road users. Fleet and transit operations account for 6,139 documents, while traffic operations account for 2,815. Other uses include sharing warnings with pedestrians and cyclists and coordinating vehicles with roadside infrastructure.
