The invention discloses a hybrid vehicle energy management method, which comprises the steps of obtaining a plurality of initialization data sets used for representing boundary values of preset numerical value intervals of target parameters under a preset condition, and obtaining a fuzzy logic control model according to each initialization data set; inputting the actual total power of a target vehicle, the charge quantity of a storage battery, the efficiency of a fuel cell and the current of the fuel cell, which are contained in the target parameters, into the fuzzy logic control model to obtain the power of the fuel cell corresponding to each initialization data set; optimizing the fuzzy logic control model according to the fuel cell power corresponding to each initialization data set. Thus, the fuzzy logic control model is optimized, the reasonable distribution of the power between the fuel cell and the storage battery is realized, and the control effect of an energy management strategy is improved.
