基于车联网的控制器远程诊断与刷写

Diagnostics and Software Updata of Vehicle Unit Based on Telematics

为了获得驾驶车辆的数据分析,避免或解决车辆控制单元在驾驶中失去功能的状态,设计和实现一种基于车联网服务平台数据分析以及远程控制器刷写的系统。该系统包括整车控制模块、车载终端、3G/4G无线通讯以及服务平台。车载终端采集整车行驶状态数据上报服务平台进行数据分析;整车控制器模块需要刷写时,服务平台通过3G/4G无线通讯下发刷写数据给车载终端,再由车载终端下发给整车控制器进行刷写。通过车型的功能应用表明该系统的数据诊断以及刷写可靠、准确可以整车对各种控制器进行数据诊断刷写。

In order to obtain the data analysis of the driving cars and to avoid or resolve the loss of functions in the driving, the design and implementation of a data analysis diagnostics and software updata system based on the telematics.The system includes a vehicle unit, vehicle terminal,3G / 4G wireless communication and service platform. Vehicle terminal acquisition vehicle driving state data reporting service platform for data analysis; when the vehicle unit needs to software updata , service platform through 3G / 4G wireless communications transmit datas to the vehicle terminal,and then datas are distributed by the vehicle terminal to the vehicle unit which needs software updata. By application,the system is reliable,accurate and can be the way for a variety of vehicle unit diagnostics and software updata.
