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.

    本发明涉及车辆散热技术领域,提供一种车辆散热控制方法及系统,其中所述车辆散热控制方法包括:检测车辆发热部件的温度、温度变化率和车辆行驶速度;确定所检测的温度和温度变化率所对应的目标冷却重要度,其中冷却重要度指示对车辆发热部件进行降温的重要程度;基于所检测的温度、温度变化率和所确定的目标冷却重要度,确定相应的冷却请求等级;基于所检测的车辆行驶速度和所确定的冷却请求等级,控制散热部件执行相应散热幅度的散热动作,其中散热幅度与车辆行驶速度和冷却请求等级之间呈正相关关系。由此,避免因高速行驶温升太快而降温不及时而导致发热部件被烧毁的风险,并保障了车辆散热控制过程中对重要发热部件的安全热管理。
