Suspension system fault diagnosis method based on fuzzy mathematics

In order to ensure the performance of vehicle suspension always in good condition, the suspension performance should be detected regularly, to identify the fault symptom and fault reason. In view of the complex correlation of the suspension symptom and fault reason, this paper puts forward the diagnosis method based on fuzzy mathematics, introduces fuzzy mathematical method into the suspension fault diagnosis, and analysis the ambiguity relationship between the fault symptom and fault reason, establishes a fuzzy comprehensive evaluation model of the suspension fault diagnosis. And by means of the state parameters method, set up the membership function model and evaluate the suspension system comprehensively according to the Maximum Subordination Principle. The typical examples show the accuracy and practicality of the model.
