摘　　要：随着汽车结构日益复杂,其故障诊断也越来越具有不确定性。文中将模糊数学思想引入汽车故障诊断过程中,建立了汽车故障诊断模型。该模型确立了汽车故障征兆与故障原因之间的模糊关系矩阵,依据最大隶属度原则确定故障原因。最后,通过实例分析,验证该模型的正确性和有效性。With the intricacy of electronic technology eonstruetion, its faults diagnosis is more uneertain. The fuzzy mathematical method was introduced in the process of auto faults diagnosis, and the faults diagnosis model for auto electric was established. The fuzzy relationship matrix between the faults symptoms and faults reason was identified, and the faults reason was determined by maximum subordination principle. At last, the model was proved to be right and effectiveness by example analysis.
