【Abstract】In this paper,the fault direction is determined through the analysis of fault phenomenon and system structure,and then the true cause of the fault is determined through FTA analysis and simulation test. Finally,the post-processing optimization scheme of this kind of problem is given,and the experimental verification on shows that it is feasible and effective.

【Key words】garage shifting;FTA;post-processing
