Make, electric machine controller 16 controls the second motor 10, the second motor 10 transfers torque to the first sun gear 15,
By the first planetary gear 12, power is transmitted to the first planet carrier 6, then by the drive pair speed change of the first planet carrier 6
Case 9, then main ratio wheel 17 and differential mechanism 13 are delivered to by auxiliary transmission 9, power is passed by differential mechanism 13
It is handed to wheel.It is adapted to city under the pattern to run at a low speed, gearratio nSecond sun gear=nSecond motor*ZFirst sun gear/(ZFirst tooth Circle+ZFirst sun gear), auxiliary transmission i=1+Z5/Z1With 1, therefore it is respectively n that output speed, which is calculated,out=nSecond motor*ZThe One sun gear/((ZFirst gear ring+ZFirst sun gear)*(1+Z5/Z1)*iBase ratio) and nout=nSecond motor*ZFirst sun gear/((ZFirst gear ring+ZFirst too Sun wheel)*iBase ratio).If battery electric quantity is less than battery management system threshold value, it can directly switch to and meet driving mould
Formula, first clutch 2 is closed, and engine start generates electricity to the first motor 3, and electric energy is carried out in time
Supplement.
Under Dual-motors Driving pattern, the clutch 5 of first clutch 2 and the 3rd unclamps, described second from
Clutch 4 is closed, and the engine 1 does not work, and the automobile power source 18 passes through the electric machine controller 16
Powered to the motor 10 of the first motor 3 and second, the common work of 3 and second motor of the first motor 10
Make the driving automotive wheel.
As shown in figure 1, during motorized motions pure using bi-motor, first clutch 2 and the pine of the 3rd clutch 5
Open, second clutch 4 is closed.Now the first gear ring 11 and the first motor 3 are directly connected to, the first sun gear
15 and second motor 10 be directly connected to.Power directly can be transmitted to by the first motor 3 and the second motor 10
One gear ring 11 and the first planetary gear 12, then drive the first planet carrier 6 to rotate by the first planetary gear 12, then
Auxiliary transmission 9 is passed to until main ratio wheel 17, differential mechanism 13 and wheel.Now, according to needed for vehicle
Rotating speed, in conjunction with auxiliary transmission gear, made respectively by control strategy two motors efficiency highest,
Exported under the minimum rotational speed and torque of energy consumption.
The pattern, in the case where obtaining identical speed, the rotating ratio list motor drive mode of the second motor 10
Rotating speed it is lower, this can make motor in higher business efficiency downward driving and can improve mileage number；And two
Under individual motor driving, the maximal rate of vehicle traveling is largely increased, and high-speed working condition is adapted in this mode
Traveling.Output speed can calculate low gear for nout=(ZFirst gear ring*nFirst motor+ZFirst sun gear*nSecond motor)/((ZFirst gear ring+ZFirst sun gear)*(1+Z5/Z1)*iBase ratio), high gear nout=(ZFirst gear ring*nFirst motor+ZFirst sun gear*nSecond motor)/((ZFirst Gear ring+ZFirst sun gear)*iBase ratio)。
Secondly, the electronic infinite variable speed device pattern includes：Hybrid mode and composite flooding pattern；Its
In,
Under hybrid mode, the first clutch 2 and second clutch 4 are closed, the 3rd clutch
Device 5 unclamps, and engine 1 and second motor 3 composition hybrid power system drive the automotive wheel,
First motor 3 is used to aid in the hybrid power system.
As shown in figure 1, using hybrid mode, first clutch 2 and second clutch 4 are closed, the
Three clutches 5 unclamp.Hybrid power system (ECVT patterns) is constituted by the motor 10 of engine 1 and second,
It is on the basis of pure electronic Dual-motors Driving, to introduce combustion engine powered under the pattern.Therefore, the first motor 3
Power output can be greatly reduced, and only provide auxiliary power, major power is provided by engine 1, therefore phase
More electronic than pure, the power output of the first motor 3 is significantly smaller, reduces battery consumption, improves battery durable
Ability；And the second motor 10 then serves as chronotropic action, engine 1 is set to have been at work under optimal fuel efficiency
Make, save fuel oil.
The pattern is more suitable for long-distance running, simultaneously as the first motor 10 has always a demand for power supply, works as cell tube
Manage system detectio to battery electric quantity less than threshold value when, or when engine is under some operating modes, not only meet
Operating mode, and unnecessary power is outputed, the first motor 3 can start working as generator, be automobile electricity
Charge and provide electric energy for the second motor 10 in pond 18.The same low gear of output speed is nout=(ZFirst gear ring*neng+ZFirst sun gear*nSecond motor)/((ZFirst gear ring+ZFirst sun gear)*(1+Z5/Z1)*iBase ratio), high gear nout=(ZFirst gear ring*neng+ZFirst sun gear*nSecond motor)/((ZFirst gear ring+ZFirst sun gear)*iBase ratio)。
Under composite flooding pattern, the clutch 5 of first clutch 2 and the 3rd is closed, second clutch
Device 4 unclamps, engine 1 and first motor 3 composition electricity generation system, and the electricity generation system is by generation
Electric energy is exported to second motor 10, and second motor 10 drives the automotive wheel.The pattern is hair
Motivation drives the first motor 3 to generate electricity, the single motor-driven composite mode of the second motor 10.
Such as Fig. 1, using electricity generation system and the composite flooding pattern of driving work simultaneously, now first clutch 2,
3rd clutch 5 is closed, and second clutch 4 unclamps.The first motor 3 is driven to constitute generating by engine 1
System is generated electricity；Because the 3rd clutch 5 is closed, the locking of the first gear ring 11, therefore the second motor 10
Drive pattern is as pure electronic single motor drive mode.Output torque and rotating speed drive with pure electronic single motor
Pattern is identical；Under the pattern, chemical energy is changed into electric energy by engine by the generating to the first motor 3,
The second motor 10 is provided power to again to work.Overcharging for battery can be effectively prevented, electricity can also be made
Pond is maintained at more than the minimum electricity of battery management system.The pattern is also to pure electronic single motor driven systems
Expand, pure electronic single motor drive mode is run at a low speed in city proper, may suffer from heavy congestion,
In particular cases battery electric quantity differs and surely supplemented in time；Institute in this mode can be to pure motorized motions mould
Under formula, timely electric energy supplement is carried out.
To sum up, the present invention proposes a kind of two grades of stepless drive systems of hybrid power electronics, and the system features are
Power coupling is carried out using single planetary gear train, the auxiliary transmission of additional two gears, structure uses ripe
Ravigneaux formula planetary gear train.The system can not only realize single motor or the pure motorized motions of bi-motor, moreover it is possible to
Realize that engine is mixed dynamic with motor, etc. various modes.And due to gear increase, power performance is improved,
There are advantageous effects for the second half speed-raising, it is to avoid whole accelerator motor works all in high energy consumption.Phase
For prior art, the present invention has advantages below：Structure is using conventional line star-wheel and ripe Ravigneaux formula
Planetary gear train, both structures are ripe, simple, it is easy to integrated；Compared with dynamic device mixed at present, if
The power of motor and volume of meter are smaller, and course continuation mileage is longer, and dynamic property is also improved；Functionally can be real
Under existing electric-only mode, single motor driving and Dual-motors Driving.Under mixed dynamic model formula, engine is mixed with motor
Close driving.Also it can realize that one group of motor MG1 constitutes electricity generation system, another group of motor MG2 by engine driving
The pattern of driving moment traveling, and two grades of variable speed can be carried out under each pattern；And the present invention's is mixed
Dynamic device can realize that oneself charges, it is not necessary to which in case of emergency power supply is looked in parking, and convenience is greatly improved；
Simultaneity factor can also carry out ramp auxiliary except combining engine start and stop, brake force energy regenerating, save
Integral vehicle cost.
