The invention discloses an engine shutdown control method, device and equipment and a storage medium. The method comprises the steps that when the vehicle works in a series working mode and receives apure electric working mode request, the torque of an engine is reduced from the current torque to the first torque, and the engine is maintained to operate at the current rotating speed through an electric generator during torque reduction of the engine; when the current torque of the engine is smaller than the first torque, the engine is controlled to be switched to a fuel cut-off state; and after the engine is in the fuel cut-off state, the electric generator is controlled to output negative torque, so that the rotating speed of the engine is lower than a rotating speed threshold value. According to the technical scheme, rapid shutdown of the engine can be ensured, and the NVH level of the whole vehicle in the shutdown process is improved.

    本发明公开了一种发动机停机控制方法、装置、设备及存储介质。该方法包括:当所述车辆工作于串联工作模式,且接收到纯电动工作模式请求时,将发动机扭矩由当前扭矩降低至第一扭矩,在所述发动机降低扭矩期间通过发电机维持所述发动机以当前转速运行;当所述发动机的当前扭矩小于所述第一扭矩时,控制所述发动机切换至断油状态;在所述发动机处于断油状态后,控制所述发电机输出负扭矩,以使所述发动机转速低于转速阈值,通过本发明的技术方案,以实现能够保证发动机快速的停机,提升停机过程中的整车NVH水平。
