摘要
本文提出了一种基于主客观评价相关性模型来确定EPS失效可控性等级的客观指标的方法。首先选取两种典型的自转向失效模式作为评估对象,并设计了驾驶员在环的主客观评价实验,然后对实验数据进行线性回归分析并构建了EPS失效可控性的主客观评价相关性模型,确定了影响EPS失效可控性等级的客观指标。最后根据ISO 26262中C2等级可控性定义对应的主观评分,基于建立的相关性模型,得出适用于本文研究工况的满足EPS失效可控性C2等级所对应的客观指标的取值。
A method to formulate objective criteria for determining EPS failure controllability level based on asubjective and objective evaluation relevance model has been proposed.Firstly,two kinds of typical unintended steering failure modes are selected as the evaluation objects.Secondly,subjective and objective evaluation experiments with the feature of driver-in-the-loop are designed.Thirdly,the linear regression analysis is carried out on the experimental data,and the correlation models of the EPS failure controllability are establishedas well as the objective criteria.Finally,according to the subjective ratings corresponding to the C2 controllability level in the ISO 26262 and the correlation models,the values of objective criteriafor determining the C2 level of EPS failure controUabilityare established.
