The invention relates to a fuel cut-off gear shifting control method and device for a vehicle, electronic equipment and a storage medium. The fuel cut-off gear shifting control method for the vehiclecomprises the steps that the fuel supply state of an engine of the vehicle is detected; if the vehicle engine is judged to be in the fuel cut-off state, whether the vehicle meets set conditions is detected, wherein the vehicle meets the set conditions that an air conditioner of the vehicle is turned on, the vehicle runs in a plateau environment or the vehicle is braked suddenly; if it is judged that the vehicle meets the set conditions, the fuel cut-off compensation rotating speed of the engine is obtained, wherein the fuel cut-off compensation rotating speed is larger than the corresponding engine fuel supply recovery rotating speed under the set conditions; and a downshift node of the vehicle is controlled according to the fuel cut-off compensation rotating speed. By means of the technical scheme, the corresponding engine rotating speed during vehicle downshifting is corrected in real time, so that the engine operates above the oil supply recovery rotating speed of the engine, the situation that oil supply of the vehicle is recovered in advance after the vehicle is powered off under the special working conditions such as air conditioner starting, plateau environment and sudden brake stepping is avoided, and then vehicle oil consumption is reduced.

    本公开涉及一种车辆的断油换挡控制方法及装置、电子设备及存储介质,车辆的断油换挡控制方法包括检测车辆发动机的供油状态;若判断车辆发动机处于断油状态,检测车辆是否满足设定条件;其中,车辆满足设定条件包括车辆的空调打开、车辆行驶于高原环境或者车辆急刹车;若判断车辆满足设定条件,获取发动机的断油补偿转速;其中,断油补偿转速大于设定条件下对应的发动机恢复供油转速;根据断油补偿转速控制车辆的降挡节点。通过本公开的技术方案,实时对车辆降挡时对应的发动机转速进行修正,以实现发动机在发动机恢复供油转速之上运行,避免出现开空调、高原环境以及急踩刹车等特殊工况下车辆在断油后提前恢复供油的情况,进而节省车辆油耗。
