摘要
目的提升老年人汽车界面满意度,设计适合老年人使用的汽车界面。方法提出基于失效模式与效应分析(FMEA)、故障树分析(FTA)的研究方法,首先成立会议小组进行SHERPA分析,绘制汽车界面层次任务分析图;随后运用FMEA找出汽车界面中的潜在失效模式,计算风险优先数值;接着选取风险优先数值高的失效模式,运用FTA寻找其发生的原因,对其以图形化表示;再对故障树进行定性定量分析,计算故障树的最小切集和失效事件发生概率,找到失效发生的核心因素;最后对失效事件进行改良并对改良后的结果进行验证。结论以老年人汽车界面为例进行研究,该方法可以有效发现老年人操作汽车界面发生错误的原因,不仅可以帮助设计师找到改良的重点,还可以使老年人获得良好的驾驶体验。
The work aims to improve the satisfaction of automobile interface for the elderly,and design a suitable automobile interface for the elderly.A research method based on failure mode and effect analysis(FMEA)and fault tree analysis(FTA)was proposed.Firstly,an expert group was set up to carry out SHERPA analysis and draw the hierarchical task analysis diagram of automobile interface.Then,the potential failure mode of automobile interface was found by FMEA and the risk priority value was calculated.Then,the failure mode with the highest risk priority value was selected and the cause of the failure was found by FTA.Graphical representation of failure causes and qualitative and quantitative analysis of fault tree were carried out.The minimum cut set of fault tree and the probability of failure events were calculated to find the core factors of failure occurrence.Finally,the failure events were improved and the improved results were verified.Taking the automobile interface for the elderly as an example,this method can find out the reasons for the errors of automobile interface operation of the elderly efficiently.It can not only help designers find the focus of improvement,but also enable the elderly to get a better driving experience.
