The invention relates to a method and device for determining the opening degree of an active air-inlet grille, electronic equipment and a medium. The method comprises the steps that the heat dissipation required power of the whole vehicle is determined according to the current vehicle speed, the current opening degree, the vehicle acceleration, the passenger compartment required temperature and the power battery required temperature; according to the vehicle heat dissipation demand power, the first pre-adjustment cooling water flow and the current vehicle speed, the pre-adjustment opening degree is determined; obtaining a second pre-adjusted cooling water flow according to the first pre-adjusted cooling water flow; according to the current vehicle speed, the current active air inlet grille opening degree, the pre-adjusting opening degree, the first pre-adjusting cooling water flow, the second pre-adjusting cooling water flow and the power limiting values of the whole vehicle NVH on a cooling fan and a cooling water pump at the current vehicle speed, the whole vehicle demand power variation combination is determined; and according to the minimum value in the whole vehicle demand power variation combination, the needed opening degree of the air inlet grille is determined. The combined control of the opening degree of the active air inlet grille can be achieved, and the combined control meets the requirements for heat dissipation, wind resistance, energy consumption, comfort and NVH.

    本发明涉及一种主动进气格栅开度的确定方法、装置、电子设备及介质。该方法包括:根据当前车速、当前开度、车辆加速度、乘员舱需求温度和动力电池需求温度,确定整车散热需求功率;根据车辆散热需求功率、第一预调节冷却水流量和当前车速,确定预调节开度;根据第一预调节冷却水流量,获取第二预调节冷却水流量;根据当前车速、当前主动进气格栅开度、预调节开度、第一、第二预调节冷却水流量、当前车速下整车NVH对冷却风扇和对冷却水泵的功率限值,确定整车需求功率变化量组合;根据整车需求功率变化量组合中的最小值,确定所需进气格栅开度。本发明可实现满足散热、风阻、能耗、舒适性、NVH多方面需求的主动进气格栅开度的联合控制。
