To make those skilled in the art more fully understand the present invention, mixing of the invention is described in detail with reference to Figure 11
The process of the working mode change control of power car.
As above, three reference factors of working mode change are：The speed of automobile, the SOC of electrokinetic cell, and vehicle
Load（It is designated as load）.Preestablish such as lower threshold value：Switching speed u, maximum SOC value S, minimum SOC value L, the first load threshold
Value a0, the second load threshold a1, the 3rd load threshold a2, the 4th load threshold a3, wherein 0<a0<a1<a2<a3<1.Such as Figure 11
It is shown to have following situation：
The speed of operating mode 1.<U, and SOC>L and Load<a0
Now the load of vehicle is smaller, and the SOC of electrokinetic cell is higher, using electric-only mode..
The speed of operating mode 2.<U, SOC≤L and Load<a0
Now the load of vehicle is smaller, and the SOC of electrokinetic cell is relatively low, using series model.Now power battery charging, makes
The SOC of electrokinetic cell is raised.
The load of 3. speeds of operating mode >=u and a0≤Load ＜ a1 now vehicle is relatively low, but because speed is higher, using parallel connection
Charge mode, now the first electric power generation, the second motor does not work, and is the situation that forerunner drives.Electrokinetic cell can now be supplemented
Electricity, raise SOC.
4. speeds of operating mode >=u and a1≤Load ＜ a2
Now the load of vehicle is higher, starts function to be worked in efficient region, now using pure engine mode.Now
First motor and the second motor are not worked, and battery is not worked, and are paralleling model, and automobile is only driven by pure engine forerunner
It is dynamic.
5. speeds of operating mode >=u and a2≤Load ＜ a3
Now the load of vehicle is very high, and now using the second motor assistant mode, motor is paralleling model with engine, the
One motor does not work, and the second motor carries out power-assisted in electric mode, now electrokinetic cell electric discharge, battery electric quantity reduction.
6. speeds of operating mode >=u and a3≤Load
Now the load of vehicle is high, now using full drive pattern.Now the first motor and the second motor are in electricity
Dynamic model formula carries out power-assisted, and gearbox output torque gives front and rear clutch by planetary gear reasonable distribution, plays drive to greatest extent
Power.Now electrokinetic cell electric discharge, battery electric quantity reduction.
The speed of operating mode 7.>0 and Load=0
Now use feedback braking pattern.Now the second electric power generation, battery charges.Battery SOC is raised.
From the foregoing, it will be observed that by different duty requirements, having formulated 7 kinds of drive patterns, using this, drive pattern can not only in 7
Preferable oil-saving effect is reached, and power performance can also be lifted, particularly in acceleration or climbing due to planetary gear energy
Reasonable distribution moment of torsion gives front and rear clutch, can to greatest extent play driving force, dynamic property is reached capacity.First motor is mainly used
Parallel connection+power generation mode in power generation cascade and paralleling model；Second motor is mainly used for pure motorized motions, tandem drive and energy
As generator during amount recovery, rear-guard power-assisted is provided during full driving.
At low speeds (referring to operating mode 1), electric-only mode is entered by controlling load signal, GES, will sent out
Low efficiency region under the slow-speed of revolution of motivation is masked.
Under parallel connection（With reference to operating mode 3,4,5,6）, different operating mould is entered by controlling load signal, GES
Formula, the low efficiency region under the high speed low torque of engine, high speed high torque is masked, and engine is always worked at efficiently
In region, fuel economy is improved.
Series model is preferentially entered when parallel connection and serial connection meets condition simultaneously（With reference to operating mode 2）, it is therefore an objective to engine work
Make point to be easily controlled, and be on most high-efficiency point, and generated output can be made relatively large, quickly can be charged to battery SOC
Desired value.
In the case of the first motor and the second motor simultaneously power-assisted, exported using planetary gear reasonable distribution gearbox and turned round
Square, makes front and rear driving force reach most preferably, realizes limit dynamic property.
Due to operating efficiency of the engine under low speed low torque, high speed low torque, high speed high torque, low speed and large torque very
Low, the operating point by adjusting engine of the invention makes the operating point of engine be in efficient region.Mode of operation of the invention
Control mode is mainly based upon the use " electric-only mode+series model " under speed operation, used under high-speed working condition " and gang mould
Formula（Charged in parallel pattern, pure engine mode, the second motor assistant mode）" principle, using electric-only mode by engine
Low speed low torque is masked with the operating point under low speed and large torque, using paralleling model that high engine speeds low torque is high with high speed
Operating point under moment of torsion masks, and then realizes that engine all has good economic performance under any operating mode.
The front/rear drive of the Motor torque coupled modes of engine+the first often occurs situation of the driving force more than adhesive force；It is single
Trailing wheel adhesive rate can not be played completely during the second motor rear-guard, in order to play adhesive rate to greatest extent, using planetary gear, and will
The output torque of gearbox section distributes to front and rear clutch, and wherein forerunner's torque distributing clutch should make the attached of front-wheel more greatly
Rate to be played to greatest extent；Rear-guard torque distributing clutch should be small, the moment of torsion and rear-guard electricity of the distribution of rear-guard clutch
The output torque of machine is coupled, and is obtained the adhesive rate of trailing wheel and is played to the limit.
