The operation of the invention is described below by the mode of operation of the hybrid transmission driveline:
(1) pure electric drive first gear and second gear mode: in the working mode, the engine 33 is shut down, the engine is in a static state due to self drag torque and speed regulation of the generator 35, the driving motor 34 starts output torque, power is transmitted to the input shaft first gear 25 and the input shaft second gear 23 fixedly connected to the driving motor input shaft 22 through the driving motor input shaft 22, and is transmitted to the second shaft first gear 27 and the second shaft second gear 21 correspondingly meshed with the input shaft first gear 25 and the input shaft second gear 23 through the sliding gear sleeve 26 and the shifting gear seat 28, and then is transmitted to the output driving gear 20 fixedly connected to the second shaft 19, and is transmitted to the output driven gear 9, and finally is transmitted to the output flange 14 through the output shaft 13, so that the vehicle is driven to run. This process gear shift is automatically accomplished by the shift mechanism 24.
(2) Driving by a generator: when the generator 35 is driven, the electromagnetic valve 8 is firstly started to ventilate the locking cylinder 6, the piston fork shaft 5 is pushed to move rightwards, the locking shifting fork 4 is driven, the locking gear sleeve 3 is shifted to be combined with the locking gear ring 2, and the engine input shaft 1 is locked.

(3) Starting the engine 33: the engine 33 can be started by using the generator 35, at this time, the generator 35 rotates to output torque, and the power of the generator 35 is transmitted to the engine 33 through the generator input shaft 30, the generator driven gear 31, the generator driving gear 7, the sun gear 15, the planet gear 17, the planet carrier 16 and the engine input shaft 1 in sequence to drive the engine to start.

When the hybrid mode is driven, the output speed ratio of the engine 33 is controlled by controlling the rotation speed of the generator 35, so that the engine always works in the optimal fuel economy area.
(6) A braking energy recovery mode: when the vehicle goes down a slope or decelerates, the inertia of the vehicle is transmitted to the output driven gear 9 through the output flange 14 and the output shaft 13, and then along the reverse line of the modes (1) and (2), the torque is transmitted to the driving motor 34 and the generator 35 to generate electricity, so that the storage battery is charged, and the energy recovery and the reutilization are realized.
