中国汽车行业实施OBD系统的宏观分析

Macroscopical Analysis for the Automotive Industry of China to Bring OBD System into Effect

车载诊断系统 (OBD)是国际上在用车应用检查 /维护制度的下一代技术。OBD的目的就是确定是否由于汽车零部件的故障导致污染物排放超过规定值。因此 ,国内引进第二代车载诊断系统OBD2是必然趋势。本文通过对OBD概念、法规、技术特征与局限性的介绍 ,针对实施OBD2对中国市场形成的巨大挑战 ,提出了OBD2的实施要求 :燃油品质必须在全国范围内得到提高 ,国内汽车行业必须做好相应的准备。最后通过综合分析给出了国内推出OBD法规分

The On-Board Diagnostics (OBD) is the new generation technology throughout the world after in-use vehicles Inspection/Maintenance program. The aim of OBD is to make sure whether there is a certain part malfunction that results in the exhaust gas pollutants exceeding the prescribed limit.So it is necessary to introduce OBD2 into the domestic market.This paper represents the concept,regulation,technical characteristic,and limitation of OBD.Clearly, it is a huge challenge to carry out OBD2 in the automobile market of China.So it brings forward the requirements of OBD2:the fuel oil quality has to be improved throughout the country,and the domestic automotive industry have to be well prepared.Finally,it lists a 4-stepp suggestions for carrying out OBD in China.
