机动车定期检验用OBD诊断仪技术要求研究

Research on the Technical Requirements of OBD Scan-Tool for Vehicle Emission Inspection

通过国内外机动车定期检验用OBD诊断仪技术要求的分析和对比,发现美国加州对OBD诊断仪的认证非常完善,而国内对OBD诊断仪还没有统一的认证要求,建议针对OBD诊断仪实际使用出现的车型覆盖不全、初始化序列不一致等问题补充认证要求,保证定期检验OBD检查的真实性和有效性。

Through the analysis and comparison of the technical requirements of OBD scan-tool for vehicle emission inspection at home and abroad, it is found that the certification of DAD is very perfect in California, while there is no unified certification requirement for OBD scan-tool in China. It is recommended that the certification requirements be supplemented for the problems such as incomplete coverage of vehicle models and inconsistent initialization sequence that appear in the actual use of OBD scan-tool, so as to ensure the authenticity and validity of OBD inspection for vehicle emission inspection.
