摘要: 车载诊断系统(On Board Diagnostics, OBD)是监测车辆废气排放量与排放污染以及监测车辆运行状态并回报异常状况的电子系统。台湾交通部道安会鉴于英国实施随车配备OBD减少了排放污染及车辆碰撞事故,乃要求近年国内各类汽车出厂一律安装OBD。因为OBD的可靠与否与车辆驾驶人的生命安全息息相关,因此OBD产品必须符合品质管理系统与可靠度验证测试标准或认证规范。本研究之主要目的是建构一套失效分析与可靠度的评估作业流程以有效改善OBD产品之可靠度。本研究以第二代车载诊断系统(OBD-II)为案例产品,藉由整合OBD-II产品由设计与制造阶段的潜在失效模式与效应分析资料以及产品使用失效后之维修回馈资料等,利用本研究所提出之失效分析与可靠度评估作业流程,制订OBD-II产品设计、制造之失效防制对策,验证了本研究方法确实可以提升OBD-II产品之可靠度。
On Board Diagnostics (OBD) is an electronic product designed for monitoring vehicle exhaust of hazardous gases and engine operation, and it also reports engine abnormal situations to vehicle driver. Knowing that the vehicle installed with OBD can effectively reduce the hazardous exhaust and traffic accidents in England, the Ministry of Communication in Taiwan decided to require all vehicles that use petrochemical fuel to have an OBD stalled. Since the safety of vehicle driver is closely related to the reliability and the quality of the OBD products, OBD product must meet their reliability test standards and conform to quality requirements. In this case, the reliability of OBD products should always be considered first. The main objective of this study is to establish a procedure to improve OBD product’s reliability and stability using failure analysis and reliability evaluation. The second generation On Board Diagnostics (OBD-II) was utilized as a case study to illustrate the effectiveness of the proposed method. The data used in this study included OBD-II FMEA data collected in the product design and manufacture stage, the failure correction and maintenance data. Through contrasting, comparing, checking and further analyzing the data using the proposed procedure, it is verified that the proposed procedure can provide an essence and effective counter-measure for fail prevention in OBD-II product design and manufacture stage, and the product reliability will thus be promoted.
