[0206] The corresponding drive motor 11 is in a non-working state, the engine clutch 4 is disengaged, and the generator clutch 6 is engaged.
[0207] Specifically, in this embodiment, under the operating condition of vehicle braking energy recovery, the engine clutch 4 is disengaged and not connected to the engine 1, and the generator clutch 6 is engaged to connect the generator 7 to the differential assembly 25, and the differential assembly 25 carries the generator 7 to achieve energy recovery.
[0208] The transmission ratio is changed by combining the low-range synchronizer 19 with the second first-stage driven gear 18, the low-range synchronizer 19 with the first first-stage driven gear 17, the high-range synchronizer 16 with the first intermediate shaft gear 13, and the high-range synchronizer 16 with the second intermediate shaft gear 14. At the same time, the engine clutch 4 is disengaged and not connected to the engine 1, and the generator clutch 6 is engaged to connect the generator 7 to the differential assembly 25, and the differential assembly 25 carries the generator 7 to achieve energy recovery.
[0209] In the above embodiment, the engine 1 and the combined drive motor 11 have torque or speed gears, and the transmission ratio changes formed by the transmission chain composed of the clutch module and the gear module form more gear states. For example, corresponding to the first gear of the engine 1, it is the first gear of the torque of the engine or the first gear of the speed. The same applies to the second gear of the engine 1, the third gear of the engine 1, and the fourth gear of the engine 1. For another example, corresponding to the first gear of the drive motor 11, it is the first gear of the torque of the drive motor or the first gear of the speed. The second gear of the drive motor 11, the third gear of the drive motor 11, and the fourth gear of the drive motor 11 are the same. For another example, corresponding to the first gear of the engine 1 combined drive motor 11, it is the first gear of the torque of the engine 1 combined drive motor 11 or the first gear of the speed, the second gear of the engine 1 combined drive motor 11, the third gear of the engine 1 combined drive motor 11, and the fourth gear of the engine 1 combined drive motor 11 are the same.
[0210] Among them, the first gear of the engine 1 combined with the drive motor 11 is to control the torque gear while matching the transmission speed of the engine 1 and the drive motor 11. For example, the drive motor 11 controls the speed in coordination with the speed of the engine 1, and then according to the increase in torque demand due to the vehicle's driving conditions (such as uphill), the drive motor 11 increases the current to increase the torque, and under the premise of the current transmission ratio, the speed control is guaranteed to be stable and the speed control ability is reduced to be affected by the road conditions.
[0211] In this embodiment, "engagement" refers to the meshing connection between gears in the gear module, "engagement" refers to the connection state of the clutch component in the clutch module, and "disengagement" refers to the disconnection state of the clutch component in the clutch module.
