Li Jiafeng Wei Zhongjin

Abstract：To improve the fault diagnosis level of the electronic control engine and create better conditions for automobile operation， this paper selects RBF neural network as the research tool， constructs the fault diagnosis function according to the operation principle of the electronic control engine， and compiles the diagnosis program in the MATLAB environment. In order to test the reliability of the fault diagnosis scheme proposed in this paper， this research has set up three kinds of fault states to simulate this fault diagnosis. The simulation results show that the fault diagnosis scheme proposed in this paper meets the requirements of improving diagnosis accuracy and diagnosis efficiency and can be popularized and applied.
