The embodiment of the invention provides a method and device for determining the target opening degree of an active air inlet grille, and relates to the technical field of electric automobiles. The method comprises the following steps: acquiring a current temperature value and a target temperature value in a vehicle, and determining a difference value between the current temperature value and the target temperature value; wherein the target temperature value is a preset in-vehicle temperature value; determining a total air volume value of the heat pump air-conditioning system according to the difference value, and calculating a total energy consumption value according to the total air volume value of the heat pump air-conditioning system; and according to the total energy consumption value, the target opening degree of the active air inlet grille is determined. By adopting the technical scheme, the overall energy consumption of the electric vehicle can be reduced as much as possible according to different temperature scenes.

    本公开实施例提供了一种主动进气格栅的目标开度确定方法及装置,涉及电动汽车技术领域。该方法包括:获取车内的当前温度值以及目标温度值,并确定当前温度值和目标温度值的差值;其中,目标温度值为预先设置的车内温度值;根据差值,确定热泵空调系统的总风量值,并根据热泵空调系统的总风量值计算总能耗值;根据总能耗值,确定主动进气格栅的目标开度。采用本技术方案,能够根据不同的温度场景,尽可能地降低电动车的整体耗能。
