Abstract:
The service reliability of the electric vehicle motor has been a consumer’s concerned topic. The service reliability of the electric vehicle motor data analysis are used the combination of ordinary least square and mathematical expectation empirical distribution function fitting method to estimate the parameters. At the same time, the neural network model and the mathematical expectation empirical distribution function are used to fit the estimation parameters, and the two methods are compared. The parameter estimation method usually used is affected by subjective factors. The benchmark of the reliability model is the empirical distribution function, and its precision affects the precision of the reliability model. In this paper, 18 electric vehicle motors with the same configuration are selected, and the failure data are collected in the same environment. The results show that the method of estimating parameters by neural network and empirical distribution function is more accurate and practical.
