[0168] Step S2: Control the transmission link of the vehicle hybrid system according to the operating conditions of the vehicle's power output.

[0169] Specifically, under different operating conditions, the engine 1 and / or the drive motor 11 work together or separately to provide load to the generator 11 and / or the differential assembly 25.

[0170] In this embodiment, controlling the transmission chain of the vehicle hybrid system according to the operating conditions of the vehicle's power output includes:

[0171] Determine whether the current vehicle power output is under a condition where only the engine is driving;

[0172] If yes, then engine 1 and generator 7 are in working condition, and drive motor 11 is in non-working condition;

[0173] Obtain gear control information;

[0174] Since engine 1 and generator 7 are in working condition and drive motor 11 is not in working condition, the transmission link is controlled according to the gear control information.

[0175] The gear control information includes the control information for engine 1 first gear, engine 1 second gear, engine 1 third gear and engine 1 fourth gear;

[0176] Corresponding to engine 1 first gear, engine clutch 4 is engaged, generator clutch 6 is engaged, and low gear synchronizer 19 is engaged with second-stage driven gear 18.

[0177] Corresponding to engine 1 second gear, engine clutch 4 is engaged, generator clutch 6 is engaged, and low gear synchronizer 19 is engaged with first stage driven gear 17.

[0179] Corresponding to the fourth gear of engine 1, engine clutch 4 is engaged, generator clutch 6 is engaged, and high-speed synchronizer 16 is engaged with the second intermediate shaft gear 14.

[0180] Specifically, in the case of engine-only operation, a four-speed transmission link is formed. During this period, engine 1 and generator 7 are in operation, while drive motor 11 is not in operation, and the load is driven only by engine 1.

[0181] In this embodiment, controlling the transmission chain of the vehicle hybrid system according to the operating conditions of the vehicle's power output includes:

[0182] Determine whether the current vehicle power output is in a state where only the drive motor is driving;

[0183] If so, then engine 1, generator 7 and drive motor 11 are in operation.

[0184] Obtain gear control information;

[0185] Based on the fact that engine 1, generator 7 and drive motor 11 are in working condition, the transmission link is controlled according to the gear control information.

[0186] The gear control information includes control information for drive motor 11 at first gear, drive motor 11 at second gear, drive motor 11 at third gear, and drive motor 11 at fourth gear.

[0187] When the drive motor 11 is in first gear, the engine clutch 4 is engaged, the generator clutch 6 is disengaged, and the low-gear synchronizer 19 is engaged with the second-stage driven gear 18.

[0188] When the drive motor 11 is in second gear, the engine clutch 4 is disengaged, the generator clutch 6 is disengaged, and the low-gear synchronizer 19 engages with the first stage driven gear 17.

[0189] Corresponding to the three gears of the drive motor 11, the engine clutch 4 is engaged, the generator clutch 6 is disengaged, and the high-speed synchronizer 16 is engaged with the first intermediate shaft gear 13.

[0190] The corresponding drive motor 11 is in fourth gear, the engine clutch 4 is disengaged, the generator clutch 6 is disengaged, and the high-speed synchronizer 16 is engaged with the second intermediate shaft gear 14.

[0191] Specifically, in the first gear of drive motor 11, engine 1 only drives generator 7 for charging, while vehicle movement is handled by drive motor 11; in the second gear of drive motor 11, engine 1 and generator 7 do not participate in the overall vehicle power output, while vehicle movement is handled by drive motor 11; in the third gear of drive motor 11, engine 1 only drives generator 7 for charging, while vehicle movement is handled by drive motor 11; in the fourth gear of drive motor 11, engine 1 and generator 7 do not participate in the overall vehicle power output, while vehicle movement is handled by drive motor 11; upshifting and downshifting are achieved by changing the gear ratio through low-gear synchronizer 19 and high-gear synchronizer 16.

[0192] In this embodiment, controlling the transmission chain of the vehicle hybrid system according to the operating conditions of the vehicle's power output includes:

[0193] Determine whether the current power output condition of the vehicle is a condition in which the engine and drive motor are driving simultaneously;

[0194] If so, then engine 1, generator 7 and drive motor 11 are all in operation;

[0195] Obtain gear control information;

[0196] Based on the fact that engine 1, generator 7 and drive motor 11 are all in working condition, the transmission link is controlled according to the gear control information.

[0197] The gear control information includes the control status of the first gear, the second gear, the third gear, and the fourth gear of the engine 1 combined drive motor 11.

[0198] When the engine 1 is combined with the drive motor 11 in first gear, the engine clutch 4 is engaged, the generator clutch 6 is engaged, and the low-gear synchronizer 19 is engaged with the second-stage driven gear 18.

[0199] When the engine 1 is combined with the drive motor 11 in second gear, the engine clutch 4 is engaged, the generator clutch 6 is engaged, and the low-gear synchronizer 19 is engaged with the first stage driven gear 17.

[0200] The engine 1 is combined with the drive motor 11 in three gears. The engine clutch 4 is engaged, the generator clutch 6 is engaged, and the high-speed synchronizer 16 is engaged with the first intermediate shaft gear 13.

[0201] The engine 1 is combined with the drive motor 11 in four gears. The engine clutch 4 is engaged, the generator clutch 6 is engaged, and the high-speed synchronizer 16 is engaged with the second intermediate shaft gear 14.

[0202] Specifically, the transmission ratio is changed by engaging the low-gear synchronizer 19 with the second-stage driven gear 18, the low-gear synchronizer 19 with the first-stage driven gear 17, the high-gear synchronizer 16 with the first intermediate shaft gear 13, and the high-gear synchronizer 16 with the second intermediate shaft gear 14. At the same time, the engine clutch 4 and the generator clutch 6 are engaged, so that the engine 1 and the drive motor 11 output power together to drive all loads.

[0203] In this embodiment, controlling the transmission chain of the vehicle hybrid system according to the operating conditions of the vehicle's power output includes:

[0204] Determine whether the current vehicle power output condition is the vehicle braking energy recovery condition;

[0205] If yes, then the drive motor 11 is in a non-working state;

[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 condition of vehicle braking energy recovery, the engine clutch 4 is disengaged and not connected to the engine 1, while the generator clutch 6 is engaged, connecting the generator 7 to the differential assembly 25. The differential assembly 25 then drives the generator 7 to achieve energy recovery.

[0208] The transmission ratio is changed by engaging the low-gear synchronizer 19 with the second-stage driven gear 18, the low-gear synchronizer 19 with the first-stage driven gear 17, the high-gear synchronizer 16 with the first intermediate shaft gear 13, and the high-gear 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, connecting the generator 7 to the differential assembly 25. The differential assembly 25 drives the generator 7 to achieve energy recovery.

[0209] In the above embodiments, engine 1 and combined drive motor 11 have torque or speed gears. Combined with the transmission ratio changes formed by the transmission link consisting of the clutch module and gear module, more gear states are created. For example, engine 1 in first gear corresponds to either engine torque or engine speed. The same applies to engine 1 in second, third, and fourth gears. Similarly, drive motor 11 in first gear corresponds to either engine torque or engine speed. The same applies to drive motor 11 in second, third, and fourth gears. Furthermore, engine 1 combined drive motor 11 in first gear corresponds to either engine torque or engine speed. The same applies to engine 1 combined drive motor 11 in second, third, and fourth gears.

[0210] In this configuration, the first gear of the engine 1 combined with the drive motor 11 controls 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 conjunction with the speed of the engine 1, and then increases the torque demand according to the vehicle's driving conditions (such as uphill driving).
