The invention provides a gear shifting control method for a hybrid power system. The gear shifting control method comprises the following steps that a gear shifting signal is received; oil is filled into the high-gear clutch and the low-gear clutch, and an engine is driven through a first motor; ignition is conducted after the engine reaches the preset rotating speed, and the first motor and the engine jointly output power; when oil charging of the high-gear clutch and the low-gear clutch is completed and the engine reaches preset torque output, the high-gear clutch is engaged and enters a slip transmission state; when the rotation speed of the engine reaches the target synchronization rotation speed of the lower-range clutch, the torque of the higher-range clutch to the lower-range clutch is handed over. The gear shifting control method for the hybrid power system has the advantages of being simple in structure, convenient to implement, convenient to manufacture and the like.

    本申请提供用于混合动力系统的换挡控制方法。该换挡控制方法包括以下步骤:接收换挡信号;对较高挡位离合器和较低挡位离合器进行充油,并且通过第一电机来带动发动机;在发动机达到预定转速之后点火,并且第一电机和发动机共同输出动力;在较高挡位离合器和较低挡位离合器充油完毕且发动机达到预定扭矩输出时,使较高挡位离合器进行接合并进入打滑传动状态;在发动机的转速达到较低挡位离合器的目标同步转速时,进行较高挡位离合器到较低挡位离合器的扭矩交接。本申请的用于混合动力系统的换挡控制方法具有结构简单、便于实施、制造方便等优点。
