Method for selecting power system configuration of heavy-duty hybrid electric vehicle

The invention discloses a heavy-duty hybrid electric vehicle power system configuration selection method which comprises the following steps: S1, selecting power system configurations of a plurality of heavy-duty hybrid electric vehicles as basic target vehicle types; S2, classifying the heavy-duty hybrid electric vehicle according to the configuration of a power system, and selecting control parameters of the vehicle under each configuration as simulation parameters; S3, based on the required power of the whole vehicle and the SOC of the battery, obtaining the output power of an engine of thehybrid electric vehicle through a fuzzy control strategy, and completing power distribution; and S4, on the basis of the power distribution result, globally optimizing the control parameters of the heavy-duty hybrid electric vehicle by adopting a genetic algorithm, simulating to obtain the fuel consumption and emission of each system configuration, and completing the selection of the power systemconfiguration on the basi
