摘　　要：针对汽车非确定性故障诊断特点,基于模糊数学理论,提出了由概率统计法及专家优序法综合确定模糊隶属度的方法,结合对故障程度的描述,建立汽车非确定性故障诊断数学模型。以此为基础,有选择地借鉴模糊数学理论中的模式识别方法对故障进行诊断,最后以实例验证了该模型的实用性。With the traits of automobile uncertain malfunction diagnosis,this paper establishes mathematic model of uncertain malfunction diagnosis of automobile based on fuzzy theory and description of malfunction degree,bringing forward the fuzzy membership grade method through probability statistic and expert preferential ordinal number.Based on all of these ,the automobile malfunction is diagnosed by using selected pattern recognition,and the model is proved practical by an example.
