The invention provides a whole vehicle thermal management control method of a pure electric vehicle. The method comprises the following steps: dividing a pure electric vehicle integrated model into a passenger compartment sub-module, a battery sub-module, a heat pump sub-module and an electric drive sub-module by adopting a modularization strategy; a BP neural network reduced-order model of each sub-module is established, and each BP neural network reduced-order model is trained; the passenger compartment sub-module, the battery sub-module, the heat pump sub-module and the electric drive sub-module are integrally fused by adopting an integrated learning algorithm to obtain an integrated thermal management system reduced-order model, and the integrated thermal management system reduced-order model fuses thermal management control data output by each trained BP neural network reduced-order model to obtain a thermal management control module. And obtaining a thermal management control strategy of the pure electric vehicle. The whole vehicle integrated neural network reduced-order model established by the invention can ensure the model precision and improve the calculation speed at the same time, so that rapid solution and online estimation are realized, and a basis is provided for the research of an intelligent control strategy of a pure electric vehicle.
