The invention relates to the 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 corresponding target cooling request level based on the detectedtemperature and the temperature change rate; and controlling a heat dissipation component to execute a heat dissipation action of a corresponding heat dissipation amplitude based on the detected vehicle running speed and the determined target cooling request level, wherein the heat dissipation amplitude is in positive correlation with the vehicle running speed and the target cooling request level.Therefore, the vehicle speed is also considered in addition to the temperature and the temperature change rate of the heating component in the heat dissipation process, heat dissipation treatment should be conducted even if the temperature is low and the driving speed is high, and the risk that the heating component is burnt down due to the fact that cooling is not conducted in time when the driving temperature rise is too high can be avoided.
本发明涉及车辆散热领域,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;基于所检测的温度和温度变化率,确定相应的目标冷却请求等级;基于所检测的车辆行驶速度和所确定的目标冷却请求等级,控制所述散热部件执行相应散热幅度的散热动作,其中所述散热幅度与所述车辆行驶速度和所述目标冷却请求等级之间呈正相关关系。由此,在散热过程中除了考虑到发热部件的温度和温度变化率外还考虑了车速,即使温度较低但行驶速度较高时也应当进行散热处理,可以避免因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。
