摘要
随着物联网产业在全国范围内的大力发展,车联网作为物联网智慧交通的重要组成部分也受到了各行各业相关领域的重视。目前国内外主流汽车品牌相继推出带有车联网系统服务的传统车及新能源车辆,然而传统的车联网业务用户黏性低,业务发展远低于预期,且多数采用2G、3G网络技术,网络时延大,上下行速率低、可靠性差。为适应车联网连续广域覆盖、热点高容量、低功耗大连接、高可靠的应用场景,所选取的车联网通信渠道就必须能够满足低时延、高速率、高频谱利用率、高可靠性等优势。本文从整车厂OEM的角度出发,介绍了目前车联网通信接入服务所采用的主流通信协议及网络制式,详细分析了两大车联网通信渠道阵营DSRC与LTE-V的优劣势,阐明了通信渠道关键技术将会在智能网联汽车领域发挥着至关重要的影响。
With the rapid development of the Internet of things industry throughout the country, the vehicle networking as an important component of the Internet of things intelligent transportation has also been the attention of various fields of vehicle networking related areas. At present, domestic and international mainstream brands have launched a vehicle networking service system of traditional cars and new energy vehicles, but the traditional car networking business user viscosity, business development is far lower than expected, and most of the 2G and 3G network technology, network delay, low rates and poor reliability. Continuous network wide coverage, high capacity, low power consumption and large hot connection, low power consumption and high reliable application scenarios in order to adapt to the car, car networking communication channels selected must be able to meet the low delay, high rate, high spectral efficiency, high reliability and other advantages. This paper from the perspective of OEM vehicle plant, introduces the main communication protocol and network standard currently used in car networking communication access service, a detailed analysis of the big two network communication channels to camp DSRC and the advantages and disadvantages of LTE-V, plays an important role to clarify the key technology of the communication channel will be in the intelligent network connected car field.
