A heat circulation system of a vehicle comprises a heat pump system, a battery system and an electric drive system, an output port of the heat pump system is connected with an input port of the electric drive system, an output port of the electric drive system is connected with an input port of a one-inlet two-outlet three-way valve, and an output port of the one-inlet two-outlet three-way valve is connected with an output port of the battery system. One output port of the one-inlet and two-outlet three-way valve is connected with an input port of the heat pump system and an input port of the battery system through a tee joint, and the other output port of the one-inlet and two-outlet three-way valve and an output port of the battery system are connected with two input ports of the two-inlet and one-outlet three-way valve. And an output port of the two-inlet and one-outlet three-way valve is connected with an input port of the electric drive system. According to the method, a joint simulation model based on a whole vehicle transmission system model, a thermal management thermal model and a control strategy model is combined and associated with a use scene, DOE multi-parameter setting is carried out on a plurality of temperature set thresholds, optimization analysis of transmission system energy loss, thermal management accessory energy consumption, battery energy loss and the like is carried out, and the control strategy model is established. And finally, according to an energy consumption optimization principle, a temperature setting threshold value is determined, and real-time regulation and control are performed.
