中文摘要：

文中基于汽车健康管理的概念提出对汽车健康状态进行评估。汽车健康状态评估作为健康管理的重要内容具有重要的现实研究意义。汽车健康状态评估的结果可以为车主提供维修提醒，为汽车维修人员提供初步维修决策，其满足汽车健康管理的需求。汽车系统是一个灰色系统，文中采用灰色理论与聚类分析相结合的灰色聚类方法进行汽车健康状态评估，根据灰色聚类决策方法的原理，分析了汽车健康状态评估指标体系，然后使用模糊层次分析法确定各指标权重，最后利用灰色聚类方法对汽车健康状态等级进行评估。实例表明，基于灰色聚类理论建立的汽车健康状态评估模型科学合理、方便快捷，并具有很好的实用性。

英文摘要：

Based on concept of automobile health management,put forward assessing health status of the automobile in this paper. Auto-mobile health status assessment as an important part of health management has important practical significance. The results of automobile health status assessment can provide vehicle owners with maintenance reminders,vehicle maintenance personnel with initial maintenance decision,which meet the needs of automobile health management. Automobile system is a gray system,in this paper use gray clustering method,which combines the gray theory with clustering methods,on automobile health status assessment. Based on gray clustering theo-ry,the index system of automobile health status assessment is analyzed,then the fuzzy hierarchical analysis method is utilized to determine the index weight,finally the level of automobile health status is estimated by gray clustering method. The result of example shows the model is convenient,scientific and reasonable,and has good practicability.
