Fig. 2 shows the signals that control method is transmitted according to the torque of the hybrid vehicle of first embodiment of the invention
Property flow chart.As shown in Fig. 2, it includes obtaining step S100, comparison step S200 and the first torque that the torque, which transmits control method,
Transmission step S300, respectively：
Step S100 obtains the speed of hybrid vehicle and the residual electric quantity of power battery；
The residual electric quantity is compared with the first default charge value, and the speed and first is preset by step S200
Speed is compared；
Step S300, when the residual electric quantity is less than the first default charge value and the speed is less than the first preset vehicle speed,
As shown in Figure 1, being linked into a gear of odd number gear 6, and first clutch 2 is engaged, to drive vehicle to travel, and is used in driving vehicle
The driving torque of traveling is transferred to the wheel 8 of hybrid vehicle by first clutch 2 and odd number gear 6；And it is linked into even number axis 5
Neutral gear, and engage second clutch 3 so that engine 1 drives motor rotation to generate electricity, be used in drive motor rotation with
The power generation torque of power generation is transferred to motor by second clutch 3.
According to the solutions of the embodiments of the present invention, since driving torque and power generation torque under the low speed are respectively by two clutches
It is independent to transmit, it in this way can be to avoid low-speed clutch large torque sliding wear problems of excessive heat.Motor passes through second clutch 3 and engine
1 is directly connected to, and is detached from wheel end, to which motor can be consistent with 1 rotating speed of engine under the low speed, thus has larger
Generated output and higher generating efficiency meet vehicle power consumption requirements and battery charge requirement, while but also with preferable warp
Ji property.
In one embodiment, the corresponding vehicle of shifting points when the first preset vehicle speed is configured as switching to two gears from a gear
Speed.Step S300 may include two kinds of operating modes, the first is that hybrid vehicle keeps off crawling in D, and second is hybrid electric vehicle
It steps on the gas in D gear low speed, speed increases, but shifting points when also not up to switching to two gears from a gear.
Under the first operating mode, engine 1 be in idling work pattern, output torque include two parts, one
Divide for driving vehicles to carry out crawlings by first clutch 2 and 6 one gear of odd number gear, another part drives electricity by even number axis 5
Machine generates electricity.
Under second of operating mode, for 1 output torque of engine unlike the first operating mode, engine 1 is to be in torque mould
Under formula, that is, the output torque part for being embodied in engine 1 is for by 6 one gear torque of first clutch 2 and odd number gear
Vehicle is driven, rather than vehicle is driven to carry out crawling.
In one embodiment, which transmits control method except including obtaining step S100, comparison step S200 and the
One torque transmission step S300 further includes the second torque transmission step.Wherein, which is, in remaining electricity
Magnitude is less than the first default charge value and speed and is increased above or when equal to the first preset vehicle speed, engages first clutch 2, together
When detach second clutch 3, and two gears of even number gear 7 are switched to from a gear, so that driving torque passes through first clutch 2 and strange
Number gear 6 is transferred to wheel 8, and makes that power generation torque passes through wheel 8 and even number gear 7 is transferred to motor.It is increased in speed supreme
When the first preset vehicle speed, need to exit the first torque transmittance process, i.e. low speed power generation mode, and enter ordinary travel
Power generation mode keeps off 7 gears to transmit power generation torque by gearbox even number, rather than by it is shown in FIG. 1 by second from
Clutch 3 transmits power generation torque.
Fig. 3 shows the operation principle of the engine mission of hybrid vehicle according to the above embodiment of the present invention
Figure, is shown the torque transmission paths in the second torque transmission step.As shown in figure 3, in the second torque transmission step,
First clutch 2 is to be in engagement state, and second clutch 3 is to be in discrete state, and power generation torque is by wheel 8
It is transferred to even number axis 5, then is transferred to motor.
It is transmitted in the torque shown in Fig. 1 and switches to the process that torque shown in Fig. 3 transmits and include：VCU unloads motor
Power generation torque, then ask engagement first clutch 2, while second clutch 3 detached, and be linked into 7 two gear of even number gear, to press
Driving torque and power generation torque are transmitted according to torque transmission paths shown in Fig. 3.
In one embodiment, which transmits the torque that control method can also include control hybrid vehicle and passes through
It is returned again to after second torque transmission step to the operation of the first torque transmission step.For carrying it under vehicle driving-cycle,
I.e. when unclamping the decline of throttle speed, allows to enter low speed power generation mode from conventional driving power generation mode, that is, turn again to Fig. 1 institutes
Show pattern.
When specific embodiment, the torque for controlling hybrid vehicle returns again to after the second torque transmission step to first
The operation of torque transmission step, including：Unload the power generation torque of the second torque transmission step；Be linked into odd number gear 6, engagement first from
Clutch 2；It is linked into the neutral gear of even number axis 5, engages second clutch 3.In one embodiment, the second torque is unloaded by VCU to pass
Pass the power generation torque of step, and VCU request engagement second clutches 3.
In one embodiment, it includes obtaining step S100, comparison step S200, first which, which transmits control method and remove,
Torque transmission step S300 and the second torque transmission step can also include third torque transmission step.The third torque transmits
Step is to engage first clutch 2 when residual electric quantity raises to above or is equal to the first default charge value, is linked into odd number gear
6, while second clutch 3 is detached, and it is linked into even number gear 7, so that driving torque is transmitted by first clutch 2 and odd number gear 6
To wheel 8, and unload power generation torque.
Fig. 4 shows the operation principle of the engine mission of hybrid vehicle according to the above embodiment of the present invention
Figure, is shown the torque transmission paths in third torque transmission step.The third torque transmission step is, in power electric
When pond electricity raises to above or is equal to the first default charge value, system needs to exit low speed power generation mode shown in FIG. 1, carries out
1 crawling pattern of engine, torque transmit as shown in Figure 4.Process from Fig. 1 to Fig. 4 is third torque transmission step, i.e. VCU
The power generation torque of motor shown in Fig. 1 is unloaded, then asks engagement first clutch 2, while detaching second clutch 3, and is linked into idol
7 two gear of number gear, to transmit driving torque and power generation torque according to torque transmission paths shown in Fig. 4.
According to the solutions of the embodiments of the present invention, it is switched to conventional driving power generation again after speed rising, not to engine 1
Only can be with one grade of odd number axis 4, third gear, five grades and seven grades of driving vehicles, it can also be with two of the even number axis 5 where motor
Shelves, fourth gear and six grades of driving vehicles, so that engine 1 can work in all gears, and motor can also pass through even number
Two grades of axis 5, fourth gear and six grades travel to vehicle and provide power-assisted or power generation.
Correspondingly, the embodiment of the present invention additionally provides a kind of torque transmission control system of hybrid vehicle, described mixed
