Abstract

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.

Description

technical field [0001] The present application relates to the technical field of new energy vehicles, in particular to a hybrid vehicle energy management method and device. Background technique [0002] With the rapid development of the vehicle industry, hybrid vehicles with fuel cells are gradually developed. This hybrid vehicle has dual energy sources, one of which can use the electricity generated by the on-board fuel cell device as energy. The other can use the electricity generated by the battery as an energy source. Therefore, in order to better distribute energy, the hybrid electric vehicle with fuel cell needs to design an energy management strategy to coordinate the energy distribution among different energy sources. [0003] In related technologies, the energy management strategy of the hybrid vehicle with fuel cells is generally a rule-based energy management strategy. The rule-based energy management strategy needs to rely on experience to formulate rules, and t...
