In order to solve the lack
of automatic transmission slippage fault data, the uncertainty of the link
between the source of the fault and the degree of failure, the lack of
applicability of the traditional Boolean logic gate, the T-S model and fuzzy
theory and the revision of the confidence index are proposed. The expert survey
method was combined and the analysis method was introduced into the fault tree.
The T-S model is introduced into the typical fault analysis, using the fuzzy
possibility to describe the failure probability of the component. The
connection between events is described with the T-S gate. The fault degree of the
component is described by the fuzzy number, the model simulation is
used to simulate the fault analysis, and the contribution or importance of the
top event to the failure of the component is obtained. The fuzzy possibility
and fault diagnosis of the top event are calculated. Without knowing the fault
mechanism accurately, we can find the weak link of the system, and provide
reference for automatic transmission slip fault diagnosis and maintenance.
