Research on Reasoning Method of Diagnosis for the Electronic Engine in Fault Knowledge

Abstract

Vehicle is a complicated mechanical system. Its fault often caused by the interactions between the hidden deep reason and multiple systems. Our work is form the electronic engine diagnosis reasoning knowledge to solve the problems of such faults. In order to make fault process and fault concept clearly, constraint relation and causal chain between fault and symptom are introduced. Problems solved including the binding interaction between ontologies, transfer process from the failure to of the final symptom, and inference rules of reasoning rules.
