The embodiment of the invention provides a control method for a hybrid power system, the hybrid power system and a controller. The hybrid power system comprises a through shaft gear pump, the through shaft gear pump comprises a first input end and a second input end, the first input end is connected with a first branch, and the second input end is connected with a second branch. Acquiring the first output torque of the engine and the residual electric quantity of the power battery in real time; under the condition that the first output torque and the residual electric quantity meet a first preset condition, a second input end of the through shaft gear pump is controlled to be communicated with a second branch; and the second output torque of the motor is adjusted to change the first output torque, so that the fuel consumption rate of the engine is increased. By introducing the through shaft gear pump comprising the two input ends, flexible matching of motor models is achieved, the cost is effectively reduced, and bidirectional power transmission of the through shaft gear pump by the engine and the motor is achieved.

    本申请实施例提供一种用于混合动力系统的控制方法、混合动力系统及控制器。混合动力系统包括贯通轴齿轮泵,贯通轴齿轮泵包括第一输入端和第二输入端,第一输入端与第一支路连接,第二输入端与第二支路连接,方法包括:在贯通轴齿轮泵的第一输入端与第一支路连通的情况下,实时获取发动机的第一输出扭矩和动力电池的剩余电量;在第一输出扭矩和剩余电量满足第一预设条件的情况下,控制贯通轴齿轮泵的第二输入端与第二支路连通;调节电机的第二输出扭矩以改变第一输出扭矩,以提高发动机的燃油消耗率。本发明通过引入包括两个输入端的贯通轴齿轮泵,实现了电机型号的灵活匹配、有效降低成本,以及实现了发动机和电机对贯通轴齿轮泵的动力双向传递。
