Door system greatly affects the vehicle’s safety and operational performance, so it is necessary and urgent to carry out reliability analysis of door system. The methodology proposed in this paper involves FTA and FRPN (Fuzzy Reasoning Petri Net) method. First, fault tree model of door system is established on the basis of failure causality analysis; second, the FRPN model is converted from a fault tree model through graphical transformation rule, and the reasoning algorithm is used to calculate the failure rate of target event. Finally, the important degree of initial events is calculated to evaluate the influence of different faults. The results show that the EDCU failure, DLS breakage, Screw/nut clamping are the most critical faults. The result is helpful for the technical personnel to assess the systems’ behavior and to improve their performance by adopting suitable maintenance strategies.
