摘要
随着汽车功能的不断增加,如自动驾驶、音视频传输、软件远程更新等,对车载通讯技术的带宽要求越来越高。车载以太网以高带宽、低成本、技术相对成熟等特点进入汽车领域,并随着车辆智能化的发展,将会成为车载网络总线的核心技术之一。本文主要阐述了以太网相关协议包括物理层编码定义、VLAN应用、TCP/IP及应用层协议在汽车产品中的应用方法,为整车厂设计以太网通信协议提供指导。
With the increasing functions of automobiles,e.g.automated driving,audio/video transmission,remote software update,so the bandwidth requirements of vehicle BUS communication technology is higher and higher.Vehicle Ethernet with high bandwidth,low cost,relatively mature technology has been introduced into the automobile industry,and with the development of automotive intelligence,Ethernet will become one of the core technologies of vehicle network,this paper mainly aims at elaborating the applicable methodologies of Ethernet technology,which includes the physical layer coding definition,application of VLAN,TCP/IP and the application layer protocol,this paper provides guide for OEMs to develop Ethernet communication protocol.
