In practical application, a hybrid electric vehicle has proved to be one of the most energy-saving, environment-friendly, mature and stable vehicle models at the present stage. The design of the oil-electricity hybrid electric vehicle not only adopts the traditional vehicle design method, but also introduces the structural elements of the vehicle electric system. Therefore, how to design a set of reasonable transmission structure and corresponding control strategy to enable the vehicle to achieve the optimal fuel economy under any working condition is the technical core for developing the fuel-electric hybrid electric vehicle.

Because of different research routes and strong competitive relationship among manufacturers, these excellent systems cannot be fallen to domestic enterprises at present. The invention is intended to provide a practical and relatively efficient and inexpensive solution in the field of hybrid vehicle transmission systems.
Disclosure of Invention

Wherein:

The half shaft A4 and the half shaft A5 are connected to two driving wheels of the automobile respectively.
The working process of the invention is as follows:
firstly, the system adopts a one-way clutch C1 to realize the power decoupling of the gear shifting action of a transmission shaft A1. The process is as follows:
controlling the throttle opening of an engine E1 to be reduced, absorbing engine energy by using a motor M1, enabling the rotating speed of an input shaft of a one-way clutch C1 to be lower than that of a low-rotating-speed gear on a transmission shaft A1, enabling the one-way clutch C1 to slide in a one-way mode, and decoupling power; at the moment, the synchronizer S1 acts to realize gear shifting; the throttle opening of the engine E1 is controlled to increase again, energy is fed back to the engine by the motor M1, the rotating speed of the input shaft of the one-way clutch C1 returns to normal, and the vehicle is driven by continuously outputting power.
In the gear shifting process of the transmission shaft A1, the motor M2 stably and continuously drives the vehicle through the transmission shaft A3, so that the control intention of a driver is realized, and the power interruption is avoided.
Secondly, a transmission shaft A3 connected with the motor M2 is subjected to a gear shifting process:
when the transmission shaft A3 connected with the motor M2 needs to be shifted, the motor M2 idles (does not output power), and the synchronizer S2 is switched to a neutral state. And then the motor M2 is quickly regulated according to the rotating speed requirement of the new gear, so that the synchronizer S2 and the new gear have the same rotating speed. Then the motor M2 idles (does not output power), and the synchronizer S2 shifts to a new gear. Finally, the motor M2 continues to output power in the new gear.
In the gear shifting process of the transmission shaft A3, the engine E1 and the motor M1 stably and continuously drive the vehicle through the transmission shaft A1, so that the control intention of a driver is realized, and the power interruption is avoided.
Third, the transmission shaft A1 and the gear G11 and the gear G12 in the system have 3 connection states through the synchronizer S1:
1. only gear G11 is connected, referred to as "front 1;
2. only gear G12 is connected, referred to as "front 2";
3. and the gear G11 and the gear G12 are not connected, and are called as the front neutral.
Fourthly, the transmission shaft A3, the gear G31 and the gear G32 in the system have 3 connection states through a synchronizer S2:
1. only gear G32 is connected, referred to as "rear 1;
2. only gear G31 is connected, referred to as "rear 2";
3. and the gear G31 and the gear G32 are not connected, and are called as 'rear neutral'.
And fifthly, combining the transmission shaft A1 and the transmission shaft A3 in one state, so that the system can realize 9 working modes:
mode 1: front neutral and rear neutral
The automobile is not connected with any power, and the wheels can rotate freely; the power output of each power source is in a suspended state.
The engine E1 can be stopped or started by the driving motor M1 and generate electricity through the motor M1.
Mode 2: front neutral + rear 1 gear
The automobile is driven by a motor M2, and the low-speed pure electric vehicle runs.
The engine E1 can be stopped, or started by the driving motor M1 and driven by the driving motor M1 to generate electricity.
Mode 3: front neutral + rear 2 gears
The automobile is driven by a motor M2 and runs purely electrically at high speed.
The engine E1 can be stopped, or started by the driving motor M1 and driven by the driving motor M1 to generate electricity.
Mode 4: front 1 gear and rear neutral gear
The automobile is driven by the engine A and the motor M1 together to run at a medium speed.
Mode 5: front 1 gear and rear 1 gear
The automobile is driven by the engine E1, the motor M1 and the motor M2 together, and runs at a low speed.
Mode 6: front 1 gear and rear 2 gear
The automobile is driven by the engine E1, the motor M1 and the motor M2 together, and runs at a medium speed.
Mode 7: front 2 + rear neutral
The automobile is driven by the engine E1 and the motor M1 together, and runs at high speed.
Mode 8: front 2 th gear and rear 1 st gear
The automobile is driven by the engine E1, the motor M1 and the motor M2 together, and runs at a medium speed.
Mode 9: front 2 + rear 2
The automobile is driven by the engine E1, the motor M1 and the motor M2 together, and runs at high speed.
The invention has the beneficial effects that:
the system employs a one-way clutch C1 to effect power shifting. The traditional dry clutch or wet clutch is omitted, the design and manufacture difficulty is reduced, the cost is saved, and the service life is prolonged.
When the system is operating in mode 2, the engine is not directly engaged in driving. The engine E1 can be started and stopped at any time through the motor M1; when the battery of the automobile is fully charged, the engine E1 is stopped; when the battery of the automobile is fed, the engine E1 works in the optimal fuel consumption rate interval and drives the motor M1 to generate electricity.
The speed ratio of the system 'rear 1 gear' and 'rear 2 gear' is not related to each other and can be designed independently, so that the 'rear 1 gear' can have enough climbing capability and low-speed acceleration performance; the "rear 2" gear may match the higher maximum vehicle speed. Another benefit of the independent transmission ratio design is that the motor M2 can operate more in the high efficiency region, thereby saving the system power.
When the system is in a mode 1 state, the motor does not follow up under the passive driving working condition of the automobile; for an automobile adopting the permanent magnet motor as the motor M2, the phenomenon of burning out high-voltage circuit devices cannot occur.
The system utilizes two power shafts (a transmission shaft 1 and a transmission shaft 3) to alternately drive the automobile, so that the automobile does not have the phenomenon of power interruption in the gear shifting process.
The system utilizes two motors, fully supports energy recovery of various strategies, and further improves the energy-saving effect of the automobile.
When the system is at high speed, the automobile is switched between the mode 6 and the mode 9 according to the charging state of the battery, and the output power of the engine is adjusted by using the energy of the battery in cooperation with the motor M2 and the motor M1, so that the engine always works in the optimal fuel consumption rate interval.
The system can be linked with all power sources, and the backup power (including the common output power of the battery and the engine) of the automobile is very high, so that the automobile has better high-speed acceleration performance.
The dynamic index of the system does not depend on the external characteristics of the engine any longer, and a high-efficiency engine (the general external characteristic index is poor) such as Miller cycle can be selected, so that the economy and the emission index of the system are improved greatly.
