摘要
摘 要：车联网作为产业变革创新的重要催化剂，正推动着交通管理模式、汽车产业形态、人们出行方式和能源消费结构的深刻变化。首先分析了智慧交通和智能驾驶等对车联网通信在通信速率、时延和可靠性等方面的需求与挑战，进而介绍了蜂窝车联网（cellular vehicle-to-everything，C-V2X）中LTE-V2X和NR-V2X的关键技术及其国际标准演进，并指出C-V2X在全球竞争中已形成超越态势。在此基础上，分析了应用C-V2X的车车协同和车路协同在智慧交通和智能驾驶中的应用优势。最后介绍了C-V2X在我国的示范应用情况和发展展望，指出中国发展智慧交通和智能网联汽车之路：将积极推进“5G+C-V2X”新型基础设施建设，探索基于车联网的“聪明的车、智慧的路、协同的云”发展模式，进而支撑我国达成“碳达峰”与“碳中和”战略目标。
Abstract
V2X (vehicle-to-everything) is a promote and profound reform-and-innovation in transportation and automobile industries.It is changing the people’s travel mobility modes and ways of society energy consumption.The requirements and challenges of V2X communication performance in data rate
latency
and reliability
being required and challenged by intelligent transportation and automated driving applications were analyzed.The critical technologies and international standards evolutions of cellular vehicle-to-everything (C-V2X) were introduced
including LTE-V2X and NR-V2X.Then
the advantages of applying C-V2X were analyzed for vehicle-vehicle and vehicle-infrastructure cooperation in intelligent transportation and automated driving.Meanwhile
the field testing and industrial practice of C-V2X in China were presented
and the roadmap was envisioned for developing intelligent transportation and intelligent connected vehicles (ICV) in China.For example
the envisions include actively promoting the construction of “5G+C-V2X” and new type infrastructure
exploring the development mode of vehicle-infrastructure cooperation based on V2X
and eventually supporting China to reach the national low “carbon peak” and to achieve the national “carbon neutralization” strategic goals.
