1. A method for controlling cooling of a vehicle, comprising:
by one or more processors, when the vehicle is operating, acquiring a current temperature value and a temperature change rate of a cooling object in the vehicle;
by one or more processors, determining a cooling demand value of the cooling object according to the current temperature value and the temperature change rate of the cooling object, and the cooling demand value is configured to describe cooling demand intensity of a corresponding cooling object; and
by one or more processors, determining an execution opening of a servo component in a cooling system of the vehicle according to a target demand value among the cooling demand values and a preset corresponding relation, and controlling the servo component to operate according to a corresponding execution opening so as to cool the cooling object, and the preset corresponding relation comprises a corresponding relation between execution opening of each of the servo components and the demand value, and the target demand value comprises a maximum value among the cooling demand values;
the step of determining the cooling demand value of the cooling object according to the current temperature value and the temperature change rate of the cooling object comprises:
according to the current temperature value and the temperature change rate of the cooling object, querying a preset cooling demand table and determining the cooling demand value of the cooling object;
wherein the cooling demand table being configured to describe a corresponding relation between a temperature value as well as the temperature change rate and the cooling demand value;
the step of determining the execution opening of the servo component in the cooling system of the vehicle according to the target demand value among the cooling demand values and the preset corresponding relation and controlling the servo component to operate according to the corresponding execution opening so as to cool the cooling object comprises:
determining the maximum value among the cooling demand values as the target demand value;
according to the target demand value, querying a control strategy table which is preset and determining the execution openings of the servo components, and the control strategy table is configured to describe the corresponding relation between the execution opening of each of the servo components and the demand value; and
according to the execution opening of the servo component, controlling a corresponding servo component to operate;
in the control strategy table, when the target demand value is less than or equal to a first cooling threshold, the execution openings corresponding to the servo components are 0;
when the target demand value is greater than or equal to a second cooling threshold, the execution openings corresponding to the servo components are an opening upper limit value; and
the second cooling threshold being greater than the first cooling threshold.
