Beschreibung
Zusammenfassung:	The invention discloses a control method for a hybrid power system, the hybrid power system comprises an engine, a motor, a first clutch, a second clutch, a transmission and a power battery, the first clutch is an electromagnetic clutch, and the control method comprises the steps that the real-time electric quantity of the power battery is obtained; determining a target working mode of the hybrid power system according to the real-time electric quantity; under the condition that the target working mode is the pure electric mode, the first clutch is controlled to be disconnected so as to control the motor to independently drive the transmission; and under the condition that the target working mode is the pure fuel oil mode, the first clutch is controlled to be engaged, and the engine is controlled to independently drive the transmission. By means of the technical scheme, the electromagnetic clutch can enable the engine and the motor to be flexibly matched with the transmission so as to achieve multiple driving
