Vehicle heat dissipation control method and system

Abstract

The invention relates to the technical field of vehicle heat dissipation, and provides a vehicle heat dissipation control method and system. The vehicle heat dissipation control method comprises the steps of detecting the temperature of a heating component of a vehicle, the temperature change rate, and the vehicle running speed; determining a target cooling importance degree corresponding to the detected temperature and the temperature change rate, wherein the cooling importance degree indicates an importance degree of cooling the heating component of the vehicle; determining a corresponding cooling request level based on the detected temperature, the temperature change rate and the determined target cooling importance degree; and based on the detected vehicle running speed and the determined cooling request level, controlling a heat dissipation component to execute a heat dissipation action of a corresponding heat dissipation amplitude, wherein the heat dissipation amplitude is in positive correlation with the running speed of the vehicle and the cooling request level. Therefore, the risk that the heating component is burnt down due to the fact that the temperature rises too fastduring high-speed driving and is not reduced in time is avoided, and safe heat management on important heating components in the vehicle heat dissipation control process is guaranteed.
