FNN-based Intelligent Fault Diagnosis System for Vehicle Engine

According to the fuzziness and complexity of a variety of vehicle engine malfunctions,a kind of FNN-based intelligent fault diagnosis system was put forward.The system has the characteristic of fast inference speed,strong fault-tolerance ability by combine the advantages of the neural networks,fuzzy logic and expert system.Fuzzy logic concept was injected on the basis that neural network makes fault diagnosis to electronic control gasoline engine and applying fuzzy membership functions to depict the fault extent.By applying GUI function of MATLAB,a new man-machine interaction interface was designed.It has a great improvement in convenient operation,facilitates to use and is simply and intuitively updated.
