The invention provides a range extender starting control method and system, a vehicle, electronic equipment and a storage medium, and relates to the technical field of range extender control, and the method comprises the steps that in the process that a generator is controlled to drag an engine to start at a first target torque set in a closed-loop torque control mode, the current rotating speed of the generator is obtained; controlling the generator to be switched from a closed-loop torque control mode to a closed-loop rotating speed control mode according to the current rotating speed of the generator; and after the engine is dragged to start according to a first target rotating speed set by the closed-loop rotating speed control mode, the torque of the generator is controlled to be reduced. In the starting process of the engine, the rotating speed of the generator can be intervened in time, and after the engine is started, the torque of the generator is controlled to be reduced in time, so that the influence of the output torque of the engine on the rotating speed of the generator is reduced, the overshoot of the rotating speed of the engine can be reduced, and the NVH noise problem in the starting process of the range extender is solved.

    本申请提供了一种增程器启动控制方法、系统、车辆、电子设备及存储介质,涉及增程器控制技术领域,所述方法包括:在控制发电机以闭环转矩控制模式所设定的第一目标转矩拖动发动机启动的过程中,获取所述发电机的当前转速;根据所述发电机的当前转速,控制所述发电机从闭环转矩控制模式切换到闭环转速控制模式;在根据所述闭环转速控制模式所设定的第一目标转速拖动所述发动机启动之后,控制所述发电机的转矩减小。本申请能够在发动机启动的过程中,及时对发电机的转速进行干预,在发动机启动之后,及时控制发电机的转矩减小,以减小发动机输出转矩对发电机转速的影响,进而能够减小发动机转速的过冲量,改善增程器启动过程中的NVH噪声问题。
