The invention provides an opening degree adjusting method and device for an active air inlet grille and a vehicle. The method comprises the steps that the reference opening degree value of the active air inlet grille is determined according to the current running state of the vehicle; determining a preset adjustment mode and a preset adjustment value of the active air inlet grille, and determining a candidate opening value according to the reference opening value, the preset adjustment mode and the preset adjustment value; determining a first energy consumption variable quantity corresponding to the wind resistance coefficient and a second energy consumption variable quantity corresponding to the cooling performance according to the candidate opening value; and whether the active air inlet grille is adjusted according to the candidate opening value or not is determined according to the first energy consumption variable quantity and the second energy consumption variable quantity. The method can ensure that the energy consumption of the whole vehicle can be reduced when the opening degree of the active air inlet grille is adjusted every time, so that the running stability of the vehicle is ensured.

    本申请提供一种主动进气格栅的开度调整方法、装置和一种车辆,其方法包括:根据车辆的当前运行状态确定主动进气格栅的基准开度值;确定主动进气格栅的预设调整方式和预设调整值,并根据基准开度值、预设调整方式和预设调整值确定候选开度值;根据候选开度值确定与风阻系数对应的第一能耗变化量和与冷却性能对应的第二能耗变化量;根据第一能耗变化量和第二能耗变化量确定是否按照候选开度值调整主动进气格栅。本方法能够保障每次调整主动进气格栅的开度都能降低车辆的整车能耗,从而保障车辆运行的稳定性。
