The first operating state may also be referred to as a full performance state, where the engine 100 and the battery 300 operate simultaneously, so that the hybrid assembly has a larger output power, thereby enabling the vehicle to have a better acceleration performance and enhancing the driving feeling.

Fig. 3 is a schematic diagram illustrating energy transmission of the hybrid assembly in a second operating state according to an embodiment of the present application. Referring to fig. 3, the engine 100 is operated alone when the hybrid assembly is in the second operating state. The power output from engine 100 is transmitted through transmission 200 to front axle 500 and hybrid rear axle 600. The power output by the engine 100 drives the front left wheel and the front right wheel to rotate through a front left half shaft 510 and a front right half shaft 520 which are connected with the front axle 500; the power output from the engine 100 rotates the rear left and right wheels via rear left and right half shafts 610, 620 connected to the hybrid rear axle 600.

Referring to fig. 4, when the hybrid assembly is in the third operating state, the battery 300 is operated alone. The battery 300 drives the motor 400 to rotate, and a part of the power output by the motor 400 is transmitted to the hybrid rear axle 600, and the rear left wheel and the rear right wheel are driven to rotate by a rear left half axle 610 and a rear right half axle 620 which are connected with the hybrid rear axle 600. Another part of the power output by the motor 400 is transmitted to the front axle 500 through the hybrid rear axle 600 and the gearbox 200, and the front left wheel and the front right wheel are driven to rotate through the front left half axle 510 and the front right half axle 520 connected with the front axle 500.

FIG. 4 illustrates a four-wheel drive mode (i.e., front left wheel, front right wheel, rear left wheel, and rear right wheel may simultaneously provide driving force); in other possible embodiments, a two-drive mode (i.e., driving force is provided only by the rear left wheel and the rear right wheel at the same time) may also be employed, in which the power output from the motor 400 is transmitted to the hybrid rear axle 600.

The third working state can also be called as a pure state, so that the oil consumption can be reduced, and the noise is lower in the driving process.

Fig. 5 is a schematic diagram illustrating energy transmission of the hybrid assembly in a fourth operating state according to an embodiment of the present application. Referring to fig. 5, the engine 100 is operated alone when the hybrid assembly is in the fourth operating state. Some of the power output from the engine 100 is transmitted to the front axle 500 and the hybrid rear axle 600 through the transmission 200, and the front left and right wheels are rotated by the front left and right half shafts 510 and 520 connected to the front axle 500, and the rear left and right wheels are rotated by the rear left and right half shafts 610 and 620 connected to the hybrid rear axle 600. Another part of the power output from engine 100 is transmitted to motor 400 through hybrid rear axle 600, and motor 400 converts the kinetic energy into electric energy to charge battery 300.

FIG. 5 illustrates a four-wheel drive mode (i.e., front left wheel, front right wheel, rear left wheel, and rear right wheel may simultaneously provide driving force); in other possible embodiments, a two-drive mode (i.e., only providing driving force through the rear left and right wheels) may be employed, where some of the power output from the engine 100 is transmitted to the hybrid rear axle 600 entirely through the transmission 200, and another of the power output from the engine 100 is transmitted to the motor 400 through the hybrid rear axle 600, and the motor 400 converts kinetic energy into electrical energy to charge the battery 300.

The fourth operation state may be also referred to as a running charge state, and may be used to charge the battery 300 during running, and is suitable for a case where driving is not very intense and there is a margin in the power of the engine 100.

Fig. 6 is a schematic diagram illustrating energy transmission of the hybrid assembly in a fifth operating state according to an embodiment of the present application. Referring to fig. 6, when the hybrid assembly is in the fifth operating state, the engine 100 is operated independently, the power output by the engine 100 is transmitted to the motor 400 through the hybrid rear axle 600, and the motor 400 converts the kinetic energy into electric energy to charge the battery 300.

The fifth operating state, which may also be referred to as a park charge state, may charge the battery 300 when the vehicle stops running, and is applicable to a case where no external charging device is available.
