车载数据终端的功能需求研究

Research on the Functional Requirements of On-board Data Terminal

车载数据终端(又称为T-BOX)是新能源汽车和智能网联汽车的关键零部件。其通过4G或5G远程无线通讯、GNSS卫星定位和CAN总线通讯功能,实现车辆的数据采集存储上传和远程指令的接收转发,从而满足远程监控、报警、远程诊断等多种在线应用的需求。同时随着智能网联汽车的快速发展,车载数据终端的功能需求也在不断的丰富。因此,如何定义车载数据终端的功能需求成为了零件系统开发过程中的关键项。本文通过一款纯电动汽车样车的开发,进行车载数据终端的功能需求研究,得出关键功能需求及定义,从而使车载数据终端能更好的为智能网联汽车服务。

On-board data terminal (also known as T-box) is a key component of new energy vehicles and intelligent connected vehicles.Through 4G or 5G remote wireless communication,GNSS satellite positioning and CAN bus communication functions,it CAN realize vehicle data collection,storage,uploading and remote instruction receiving and forwarding,so as to meet the needs of remote monitoring,alarm,remote diagnosis and other online applications.At the same time,with the rapid development of intelligent connected vehicles,the functional requirements of on-board data terminals are also constantly enriched.Therefore,how to define the functional requirements of on-board data terminal has become a key item in the process of parts system development.In this paper,through the development of a pure electric vehicle sample,the functional requirements of on-board data terminals are studied,and the key functional requirements and definitions are obtained,so that the on-board data terminals can better serve intelligent networked vehicles.
