The invention discloses an extended-range hybrid vehicle MPC energy management strategy time domain adjustment method, which comprises the following steps: acquiring historical working condition data of a hybrid vehicle, and preprocessing the historical working condition data to obtain a historical working condition data set; training the RBF neural network prediction model based on the historical working condition data set, and obtaining a trained RBF neural network prediction model after optimization and parameter adjustment; obtaining a feature vector of the current working condition, and inputting the feature vector of the current working condition into the trained RBF neural network prediction model to obtain a prediction working condition; constructing a fuzzy logic controller, and inputting the predicted working condition into the fuzzy logic controller to obtain a predicted time domain length; and on the basis of the predicted time domain length, a global optimal control strategy is obtained in combination with an MPC controller of DP dynamic programming, and the global optimal control strategy is sent to a bottom layer controller. According to the method, the appropriate MPC time domain and the global optimal control strategy are obtained, and the local optimization result and the fuel economy are improved.
