Thermal management and control method and device, storage medium, and vehicle

A non-transitory computer-readable storage medium, storing a computer program, the computer program being executed by a processor to cause the processor to perform operations of a thermal management system of an engine, wherein

• the thermal management system comprises a water pump, an air-cooling radiator, and a thermostat, and the engine is connected with the water pump;
• and the air-cooling radiator is connected with the engine and the water pump through the thermostat,
• the operations comprise:
• querying a minimum engine fuel consumption lookup table based on a current rotation speed of the engine, a current torque of the engine, and a current ambient temperature when a current temperature of the engine is greater than or equal to a temperature threshold and an opening degree of the thermostat is greater than or equal to an opening degree threshold, and determining a total target amount of to-be-dissipated heat of the engine;
• querying a minimum thermal management system power consumption lookup table based on the total target amount of to-be-dissipated heat, an air inlet speed of the air-cooling radiator, and the current ambient temperature, and determining a target rotation speed of the water pump and a target rotation speed of the air-cooling radiator;
• and
• controlling a rotation speed of the water pump to be the target rotation speed of the water pump, and controlling a rotation speed of the air-cooling radiator to be the target rotation speed of the air-cooling radiator.
