Abstract

Abstract: The integrated transmission device possesses some inherent characteristics of the multiple working modes, discontinuity, multi-coupling, which lead to problems such as the fault detection difficulty and fault isolation inaccuracy. Analyzed in detail the structure and working principle of torque converter compensation circuit, the bond graph modeling and diagnosis methods were studied. Then the relationship between global analytical redundancy and fault characteristic matrix is established, which accurately accomplishes the fault detection and isolation. Finally, the rules between the analytical redundancy relations and different faults are verified by simulation experiments, which indicate that the design and application of FDI based on GARRs method is feasible for the hybrid system. This method provides a new technology for the sensors optimization configuration and the testability growth for the new equipment.
