Proactive Reliability Analysis for Electric Vehicles

Abstract:

In this paper, a proactive strategy is proposed to analyze the system reliability in electric vehicles (EVs). The EVs system reliability is crucial and difficult to estimate because more electrical subsystems are employed such that the system is more complicated. Besides the component failure, we consider the uncertain dependency between components by using uncertain the logical structures of failure. The proposed method is theoretically based on the probabilistic graphical model. Therefore other tasks related to system reliability, such as fault diagnosis, can be converted to the inference problems of graphical model. Simulation examples demonstrate the effectiveness of our strategy.
