Technology Study on Automobile Fault Diagnosis based on FPN

As the development of automobile technology,the corresponding devices are more and more advanced,and more and more complex,so it makes the diagnosis technology for automobile fault more and more difficult.Because of its characteristics adapting to dynamic feature of described system,Petri net is systematic modeling tool,and is widely applied in the field of automobile fault diagnosis.Through the summarization of study development on applying FPN to automobile fault diagnosis in recent years,it is visual,specific and easy to realize for maintaining data with computer.It can effectively find out the cause of automobile fault,and puts forward maintenance method to achieve the goal of maintenance.
