| 摘 要： | 随着社会的快速发展，各行各业更追求效率与安全，汽车的发展也是如此。人驾驶汽车时存在很多主观因素，会不可避免有许多视野盲区和路况信息，容易造成安全事故和交通拥堵的情况。在自动驾驶逐步推广的今天，蜂窝车联网（C-V2X，Cellular Vehicle-to everything）技术可以很好的实现汽车与汽车、汽车与交通设施的互联互通，不仅能为驾驶员提前警示危险，也助于推动自动驾驶汽车的发展。本文先讲述C-V2X的概念和网联车的相关设备。结合国内外的网联车主流的发展技术进行对比，即DSRC车用通信技术与C-V2X车用通信技术对比，突出C-V2X车用通信技术在现今发展的优势。通过对比欧洲、美国、韩国、日本、中国的C-V2X发展现状，表明中国虽然在网联车方面起步虽晚，但在无锡市建立了全球首个真实开放交通环境下的城市级示范地。本文也选取了比较典型的直道和交叉路口对通信设备不同情境下的通信能力进行测试，得出相关结论为未来的网联汽车发展起到推动作用。 |

| Abstract: | With the rapid development of society, all walks of life are more pursuing efficiency and safety, so is the development of automobiles. When driving a car, there are many subjective factors, there will be a lot of visual blind areas and road information, which is easy to cause safety accidents and traffic congestion. Nowadays, with the gradual promotion of autonomous driving, C-V2X (Cellular Vehicle-to everything) technology can well realize the interconnection between cars and cars and between cars and transportation facilities, which can not only warn drivers of dangers in advance, but also help promote the development of autonomous vehicles. This paper first describes the concept of c-v2x and the related equipment of the network. Combining the development technology of the network owner of the network, the DSRC vehicle USES communication technology to compare the communication technology of the c-v2x car, and the advantages of the communication technology of the c-v2x vehicle are present. By comparing the development of c-v2x in Europe, the United States, South Korea, Japan and China, it is a sign that China has been a late, but late, in the city of wuxi, the first urban demonstration site in the world's first real open transport environment. This paper also selects the corresponding communication ability of communication equipment in different situations, and concludes that the relevant conclusions will promote the development of the network. |
