Gear shifting control method for hybrid power system

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
