Specifically, battery 2 is that the first motor 4 and the second motor 7 provide electric energy by inverter 10, makes the He of the first motor 4
Second motor 7 has power.At the same time, power is sequentially transferred to the first driving gear 301, the first driven tooth by engine 1
Take turns the 302, first motor 4, and with the power coupling of the first motor 4, then power the first clutch is sequentially transferred to by the first motor 4
Device 5, the second driving gear 801, the 3rd driven gear 803, the second motor 7 power is sequentially transferred to the 3rd driving gear 802,
3rd driven gear 803, and with being transferred to the power coupling of the 3rd driven gear 803 by the first motor 4, then power is by the 3rd
Driven gear 803 is sequentially transferred to the 4th driving gear 804, the 4th driven gear 805, wheel 9, so that wheel 9 rotates, that is, sends out
Motivation 1, the first motor 4,7 common driving moment 9 of the second motor rotate.
In this mode, second clutch 6 disconnects, and has cut off the power transmission between the motor 7 of engine 1 and second, has kept away
1 two different power paths of engine are exempted from because speed than difference causes gear clamping stagnation.
In above-mentioned pattern, engine 1, the first motor 4 or the second motor 7 can be allowed according to the demand of different moments of torsion
Efficient operation, two kinds of mode of operations given below：
As the first mode of operation：1 and second motor of engine, 7 common driving moment 9 rotates, the basis of the first motor 4
The efficiency of engine 1 may be at not working or generating two states.When the first motor 4 is in generating state, Ke Yitong
Cross inverter 10 to power for the second motor 7, unnecessary electric energy can be stored in battery 2.
As second of mode of operation：Whether engine 1 is operated alone wheel 9 and rotated, according to engine 1 in high efficient district work
Make, to make the first motor 4 and/or the second motor 7 dally, generate electricity.
As second of mode of operation, as shown in Figure 4, in combination drive pattern, engine 1 works, the first clutch
Device 5 is disconnected, and second clutch 6 engages, and power is transferred to the second motor 7 by engine 1, meanwhile, battery 2 is the He of the first motor 4
Second motor 7 provides electric energy, is rotated by engine 1, the first motor 4,7 common driving moment 9 of the second motor.
Specifically, battery 2 is that the first motor 4 and the second motor 7 are powered by inverter 10, makes the first motor 4 and second
Motor 7 rotates.The power of first motor 4 is sequentially transferred to the first driven gear 302, the first driving gear 301, and by engine
1 is transferred to the power coupling of the first driving gear 301, and then the power is sequentially transferred to the second driven gear 303, the second clutch

Rotate, i.e., engine 1, the first motor 4,7 common driving moment 9 of the second motor rotate.
In this mode, first clutch 5 disconnects, and has cut off the power transmission between the second motor 7 and wheel 9, has avoided
Engine 1 two different power paths than difference cause gear clamping stagnation because of speed.
In above-mentioned pattern, engine 1, the first motor 4 or the second motor 7 can be allowed according to the demand of different moments of torsion
Efficient operation, two kinds of mode of operations given below：
As the first mode of operation：1 and second motor of engine, 7 common driving moment 9 rotates, the basis of the first motor 4
The efficiency of engine 1 may be at not working or generating two states.When the first motor 4 is in generating state, Ke Yitong
Cross inverter 10 to power for the second motor 7, unnecessary electric energy can be stored in battery 2.
As second of mode of operation：Whether engine 1 is operated alone wheel 9 and rotated, according to engine 1 in high efficient district work
Make, to make the first motor 4 and/or the second motor 7 dally, generate electricity.
Increase journey pattern to enable when the fuel consumption of engine 1 is larger, operating efficiency is relatively low, in order to give full play to engine
The energy that fossil fuel discharges in 1, changes into electric energy, then pass through electric energy by increasing journey pattern by energy unnecessary in engine 1
Driving automotive wheel 9 rotates, and improves the service efficiency of fossil fuel.
As shown in Figure 5, in journey pattern is increased, engine 1 works, and first clutch 5 and second clutch 6 disconnect,
It is that the second motor 7 is powered by the motor 4 of engine 1 and first, battery 2, and is rotated by the driving moment 9 of the second motor 7.
In this mode, power is sequentially transferred to the first driving gear 301, the first driven gear 302, by engine 1
One motor 4, because first clutch 5 disconnects, therefore the mechanical energy supplied by engine 1 is converted into electric energy by the first motor 4, and is led to
Cross inverter 10 to power for the second motor 7, unnecessary electricity is then stored to battery 2.Power is sequentially transferred to the 3rd by the second motor 7

In battery 2.
When the energy recuperation mode is adapted to demand braking force smaller, the mechanical energy that wheel 9 is braked only is passed through into the second motor 7
Power storage is converted into, realizes low energy recovery.
As second of example：In energy recuperation mode, engine 1 does not work, and first clutch 5 engages, second from
Clutch 6 disconnects, and wheel 9 provides mechanical energy for the first motor 4 and the second motor 7 simultaneously, and the first motor 4 and the second motor 7 are distinguished
The mechanical energy of acquisition is converted into electric energy, and is stored in battery 2.
Specifically, it is driven to be sequentially transferred to the 4th driven gear 805, the 4th driving gear the 804, the 3rd by wheel 9 for power
Gear 803, the second driving gear 801 and the 3rd driving gear 802, and respectively by the second driving gear 801 and the 3rd driving tooth
