C-V2X(Cellular V2X) 표준 특허 동향 분석

C-V2X (Cellular V2X, Cellular Vehicle-to-Everything) is a technology designed to enable vehicles to communicate while moving in the cooperative intelligent transport system and also allowing transportation participants to communicate without restrictions. C-V2X refers to V2X technology based on standards related to cellular communication defined by the 3GPP international standardization organization, and is a technology that encompasses technologies that support vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and vehicle-to-network (V2N) communication In C-V2X, data is transmitted in real time based on 4G LTE and 5G networks, and C-V2X includes all technologies that allow vehicles to exchange real-time information with the surrounding environment equipped with appropriate communication functions, such as traffic accident prevention, traffic flow optimization, and autonomous driving. In this paper, based on patents applied for, published, and registered through IP5, the world top five patent office, in relation to V2X and sidelink(V2X link) for C-V2X, we analyze patent trends by standardization stage, patent trends by issuing country, and patent trends by applicant nationality to accurately understand the technological maturity, predict the development direction of V2X technology, and derive measures to strengthen technological competitiveness.
