The invention discloses a control method of an active air-inlet grille system, the active air-inlet grille system and a vehicle. The control method of the active air-inlet grille system comprises the steps that under the condition that the active air-inlet grille system does not meet a preset full-open condition, the active air-inlet grille system does not meet the preset full-open condition; the actual rotating speed value of the engine, the actual output torque of the engine, the actual water temperature of the engine and the actual air inlet temperature of the engine are obtained; determining a first opening value according to the actual rotating speed value and the actual water temperature; determining a second opening value according to the actual output torque and the actual air inlet temperature; the basic opening value of the active air-inlet grille is determined according to the first opening value and the second opening value, the basic opening value can be determined by combining the predicted thermal state of the engine through the method, and therefore the problem that hysteresis exists when the temperature of the engine is adjusted only according to the basic opening value determined according to the actual temperature of the engine is solved; and the accuracy of the obtained basic opening value is relatively high.

    本发明公开了一种主动进气格栅系统的控制方法、主动进气格栅系统和车辆,所述主动进气格栅系统的控制方法包括:在所述主动进气格栅系统未满足预设全开条件的情况下,获取所述发动机的实际转速值、所述发动机的实际输出扭矩、所述发动机的实际水温和所述发动机的实际进气温度;根据所述实际转速值和所述实际水温确定第一开度值;根据所述实际输出扭矩和所述实际进气温度确定第二开度值;根据所述第一开度值和所述第二开度值确定所述主动进气格栅的基础开度值,采用该方法可以结合发动机的预测热状态确定基础开度值,从而解决只根据发动机实际温度确定的基础开度值来调节发动机温度时存在滞后性的问题,并且所获得的基础开度值的准确性较高。
