Abstract: A thermal management and control method includes: determining a total target amount of to-be-dissipated heat of an engine based on a minimum engine fuel consumption lookup table 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; 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 an air-cooling radiator, and a current ambient temperature, and determining a target rotation speed of a 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.
