解析：大数据汽车电子故障远程在线诊断技术的应用

摘要

随着汽车电子化程度日益提高，通过移动互联与大数据的运用，对行驶中的汽车电子控制系统(燃油喷射系统、自动变速器、制动防抱死系统、安全气囊、空调、悬架等)进行远程在线诊断(On Board Diagnostic)，将自动诊断所得到的汽车主要部件的工作状态与系统故障（故障码及数据流）利用移动互联与大数据连接到服务中心，并进行远程车辆诊断，以便随时为驾乘人员以及维修人员提供准确的故障位置和原因成为必然。%With the increasing improvement of automotive electronization, it is inevitable to apply the mobile internet and big data to conduct the On Board Diagnostic of the electronic control system (fuel injection system, automatic transmission, anti lock braking system, airbag, air conditioning, suspension) of automobile, then send the working conditions and system failures (DTCs and data stream) of main automobile parts to the service center and conduct remote vehicle diagnostics, so as to provide accurate fault location and cause to passengers and maintenance personnel.
