With continued reference to Fig. 2, it is shown that the air throttle turbogenerator 202 in engine system 200, should Engine system 200 includes the electromotor 10 described above with reference to Fig. 1.Air throttle turbogenerator The throttle valve bypass valve 208 that 202 include turbine 206, is arranged in throttle bypass 204 and by This turbo-driven auxiliary generator 210.In certain embodiments, air throttle turbogenerator can To include throttle valve bypass valve 208.As an alternative, air throttle can have the valve block of wedge shape, Such as, under the conditions of some, this wedge shape valve block stops the air-flow entering throttle bypass.
Air throttle turbogenerator 202 utilizes generally to be wasted by carrying out engine charge throttling Energy.Such as, the pressure change of air throttle 62 can be used to guide air-flow to pass through turbine 206. Turbine 206 is driven to battery 212 and provides the auxiliary generator 210 of electric current.In this configuration, Such as, because in some conditions via mechanically operated main generator 214 filling battery 212 Electricity can reduce, and can increase via the charging of auxiliary generator 210, therefore electromotor system The aggregate efficiency of system is enhanced.
As it can be seen, inlet channel 42 and air throttle 62 are flow through in air inlet.As it has been described above, air throttle Position can be changed, so that the air inflow being supplied to engine cylinder changes by controller 12 Become.Air inlet is walked around air throttle 62 from the position of air throttle 62 upstream and is guided by throttle bypass 204 Position to air throttle 62 downstream.Air inlet such as can due to the pressure differential at air throttle two ends quilt Guide by throttle bypass 204.And, in the example embodiment shown in Fig. 2, air throttle Turbogenerator 202 includes throttle valve bypass valve 208.As below with reference to described by Fig. 3, Throttle valve bypass valve 208 can be modulated to regulate the charge flow rate by throttle bypass 204. In some instances, throttle valve bypass valve 208 can be to open and close throttle bypass 204 Close/open valve.In other examples, throttle valve bypass valve 208 can be to control to pass through throttle bypass The flow modulation valve of the variable of the air-flow of 204.Throttle valve bypass valve 208 can be plunger valve, Guiding valve, gate valve, butterfly valve or other suitable volume control devices.And, throttle valve bypass valve 208 can be by solenoid, pulse width modulation solenoid, DC motor, motor, true Empty diaphragms etc. activate.
The air-flow being conducted through throttle bypass 204 flows through turbine 206, this turbine 206 with from The energy that this air-flow extracts rotates auxiliary generator 210.Auxiliary generator 210 produces supply battery The electric current of 212.Battery 212 can be the electric power of the vehicle that engine system 200 is disposed therein The various parts of system provide electric power, such as lamp, pump, electric fan, fuel injector, lighter, Air-conditioning etc..Battery 212 can also be charged by by the mechanically operated main generator of electromotor 10 214. As below with reference to described by Fig. 4, the charging of battery 212 can be at main generator 214 and auxiliary Help and coordinate between electromotor 210, thus improve the aggregate efficiency of this system.Such as, auxiliary generator 210 in the state when providing current to battery 212 by increase fuel consumption from main generator 214 Period, such as, during vehicle slowly travels or accelerates, can be that battery 212 provides electric current.And And, when main generator 214 is degenerated or breaks down, auxiliary generator 210 can be battery 212 Electric current is provided.Auxiliary generator 210 can be small power generator, such as, produces than main generating The electric current that machine 214 is few.
Fig. 3-5 illustrates to illustrate have air throttle turbogenerator, such as above ginseng for operation Examine the flow process of the control program of the engine system of air throttle turbogenerator 202 described by Fig. 2 Figure.The flow chart of Fig. 3 illustrate for according to enter electromotor air-flow regulation throttle valve bypass valve with Control by throttle bypass and therefore by the control program of the air-flow of turbine.The flow process of Fig. 4 Illustrate for being electricity via air throttle turbogenerator (such as auxiliary generator) and main generator The control program of pond charging.The flow chart of Fig. 5 illustrates for during instant engine operating mode, example As when throttle position Rapid Variable Design and/or turbine trip speed change, regulation enters the air-flow of cylinder Control program.Each program can performed the most in the same time by same controller or performed simultaneously. For example, it is possible to be battery controlling via the either or both of which of auxiliary generator and main generator While charging, control throttle valve bypass valve to regulate the air-flow by throttle bypass.As separately One example, during transient behaviour, can regulate based on by the air-flow of the change of air throttle Throttle valve bypass valve.
Fig. 3 illustrates and illustrates for regulating throttle valve bypass valve, such as, retouched above with reference to Fig. 2 The throttle valve bypass valve 208 stated is to control the air-flow control program 300 by throttle bypass.Tool Body is said, program 300 determines the air-flow entering electromotor, and based on this air-flow, regulates this solar term The position of door bypass valve.In some instances, controller can be PID (PID) Controller.In other examples, controller can utilize opened loop control, or open loop component (component) feedback is added.Such as, this feedback can be air-flow, and this air-flow can be real What border was measured enters the air-flow of engine cylinder and/or turns based on air-distributor pressure and/or electromotor The air-flow of speed.
In the 302 of program 300, determine operating mode.This operating mode can include engine speed, start Airborne lotus, intake air temperature and/or pressure (MAP) and/or flow rate (MAF) etc..
Once it is determined that after operating mode, program 300 proceeds to 304, determine that air-flow is the least 304 In thresholding air-flow.Can be the air-flow when pre-test for this air-flow determined, or from such as starting The current air-flow that other parametric inferences of machine rotating speed and MAP go out, or based on all moments of torsion as desired The current desired air-flow of other parameters.Or can be based on measuring for this air-flow determined Infer or imminent air-flow that desired parameter is anticipated.The thresholding determined for this Air-flow it may be that such as, for the minimum air flow required for turbine drive auxiliary generator.One In a little examples, this thresholding air-flow can be steady state value.In other examples, this thresholding air-flow is permissible Based on such as engine speed, engine load, intake air temperature and/or pressure and engine temperature One or more operating parameters and change.
If it is determined that air-flow is less than this thresholding air-flow, then program 300 proceeds to 308 and closes this Throttle valve bypass valve.In some instances, this throttle valve bypass valve can be switch valve and solar term Door bypass valve is by cutting out this throttle valve bypass valve regulation to make position.In other examples In, this throttle valve bypass valve can be flow modulation valve.In such an example, can be regulated this Throttle valve bypass valve to of completely closed position to close this throttle valve bypass valve.For example, it is possible to Throttle valve bypass valve is regulated to of completely closed position during the such as operating mode of tickover state.
On the other hand, if it is determined that air-flow is more than this thresholding air-flow, then program 300 proceeds to 306, At 306 regulation throttle valve bypass valve opening and throttle positions, enter engine cylinder to maintain Air-flow thus meet torque demand.Such as when torque demand increases, air throttle position can be regulated Put so that air throttle is opened more and increased by the air-flow of air throttle.Equally, moment of torsion is worked as When requiring to increase, throttle valve bypass valve can be regulated so that this throttle bypass opens increase. But, in some instances, beating of throttle valve bypass valve can be reduced when throttle position increases Open.Such as, when the state of charge of the battery charged by air throttle turbogenerator reaches threshold value And when no longer expecting to be charged by air throttle turbogenerator, opening of throttle bypass can reduce Or close.As another example, when throttle position reaches the position of wide opening air throttle, Throttle bypass opening can be closed.
In this way it is possible to control throttle valve bypass valve so that maintain the phase entering electromotor The air-flow hoped.Such as, when air-flow is less than thresholding air-flow, valve opening is closed so that not gas Stream passes through throttle bypass.When air-flow more than thresholding air-flow time, regulation valve open with valve position so that The air-flow entering engine cylinder makes the charging carrying out battery meet torque demand simultaneously, if If expecting.
Fig. 4 illustrate illustrate for the battery in engine system (such as above with reference to Fig. 2 The battery 212 described) flow chart of control program 400 that charges.Specifically, program 400 is true Determine the state of charge of battery.State of charge based on battery and other operating mode (such as vehicle deceleration, Main generator degeneration etc.), via in air throttle turbogenerator and mechanically operated main generator One or more realizes the charging of battery.
In the 402 of program 400, determine that whether the state of charge (SOC) of battery is more than first Limit value.This first threshold value is it may be that such as corresponding to battery is fully charged or the electricity of maximum charge The high threshold of lotus state.If it is determined that the state of charge of battery is more than this first threshold value, then program 400 proceed to 412 and charge battery without main generator or air throttle turbogenerator.
On the other hand, if it is determined that the state of charge of battery is less than the first threshold value, then program 400 Proceed to 404, and determine that whether the state of charge of battery is less than the second threshold value.This second Limit value can correspond to the low threshold of the minimum charge level of battery, less than this minimum charging water Flat, battery is not provided that the enough electric power of the various parts of the power system for running vehicle.Make For another example, the second thresholding can correspond to provide within one period of specific persistent period The charge level of electric power.Therefore, the second threshold value is less than the first threshold value.
If it is determined that the state of charge of battery is more than the second threshold value, then program 400 proceeds to 406, Determining whether vehicle slows down 406, the most whether car speed reduces, if vehicle driver Not to accelerator pedal apply pressure, if vehicle driver to vehicle brake apply pressure and/ Or vehicle deceleration in other suitable manners.
If it is determined that vehicle slows down, then program 400 proceeds to 408, main at 408 batteries Electromotor and air throttle turbogenerator (such as, auxiliary generator) charging.In the vehicle deceleration phase Between, main generator such as can produce electric current so that battery charging is not increased combustion via regenerative braking Material consumes.And, auxiliary generator can also provide electric current to charge battery.By this way, During vehicle deceleration, the charging of battery can be maximized.
On the other hand, if it is determined that vehicle is not to slow down, then program 400 proceeds to 410, And with air throttle turbogenerator, battery is charged.Such as, it is more than due to the state of charge of battery Second threshold value and owing to battery charging can be increased via main generator during non-deceleration regime Refuelling consumes, and battery can be only via by the turbo-driven auxiliary of air throttle turbogenerator Generator charging.
Return to 404, if it is determined that the state of charge of battery is less than the second threshold value, then program 400 Proceed to 414, determine whether main generator degenerates 414.Such as, electromotor degeneration can be with base In the minimizing produced by this electromotor curtage level, electric current or electricity can not be provided for battery Pressure etc. determines.
If it is determined that main generator is degenerated, then program 400 proceeds to 420 and makes in inlet manifold Vacuum maximize so that via turbine battery charge increase.Such as increase inlet manifold In vacuum will increase the pressure differential at air throttle two ends, thus increase and enter entering in throttle bypass The flow of gas and increase turbine can energy.For example, it is possible to by regulation air-fuel ratio, row Gas recirculation (EGR), variable valve timing, gear ratio, forbidden energy cylinder deactivation and joining machine Tool drive vacuum pump in one or more, air-distributor vacuum can be increased.Show at one In example, gear ratio can be regulated by downshift, thus increase the vacuum in inlet manifold.As Another example, it is possible to reduce the amount of exhaust gas recirculatioon is to increase the vacuum in inlet manifold.Separately In one example, air-fuel ratio (such as, running stoichiometric(al) rather than dilute proportioning) can be reduced To increase the vacuum in inlet manifold.
In some instances, i.e. box lunch main generator can also take this action to increase when not degenerating Add air-distributor vacuum, thus increase the charging carried out by auxiliary generator.But, it is however generally that, These action may increase fuel consumption, thus reduces fuel economy.In some instances, control Device processed can calculate the fuel economy penalty increasing air-distributor vacuum to running main generator , and select to increase the more efficient way that the electric power of battery is exported (penalty).
On the other hand, if it is determined that main generator is not degenerated, then program 400 proceeds to 416, 416 determine that vehicle the most slows down.As described above, determine that vehicle the most slows down, The most whether car speed reduces, if vehicle driver does not applies pressure to accelerator pedal Power, if vehicle driver applies pressure and/or car in other suitable manners to vehicle brake Slow down.
If it is determined that vehicle slows down, as it has been described above, program 400 proceed to 408 and via Air throttle turbogenerator and main generator are battery charging.Such as, because via auxiliary generator Charge for battery with main generator, simultaneously because charge to fuel economy with main generator Impact reduces, so the charging of battery can be maximized.
On the other hand, if it is determined that vehicle is not to slow down, then program 400 proceeds to 418 also And with air throttle turbogenerator, the charging of battery is allowed as many with air-distributor vacuum, and And only with main generator, the charging of battery is sufficient for total charging of desired battery.Such as, by Can reduce, the most only via auxiliary generator by increasing air-distributor vacuum in fuel economy The as many electric current that the charging of battery is allowed with inlet manifold.Similarly, since main generator meeting Reducing fuel economy, therefore main generator can run and only be sufficient for battery always charge to produce The electric current for battery.Therefore, in some instances, provide for battery from auxiliary generator Current ratio main generator many (such as, when the pressure drop at air throttle two ends is relatively high).At other In example, the electric current provided for battery from main generator can than auxiliary generator more (such as, When the pressure drop at air throttle two ends is relatively low).
By this way, the charging of battery can be coordinated between main generator and auxiliary generator, So that overall system efficiency increases.Such as, when fuel economy penalty (penalty) is low Deceleration during, electric current can be supplied to battery from auxiliary generator and main generator, thus The charging making battery is maximum.During state when when fuel economy penalty height, electric current is only from auxiliary Electromotor is helped to be supplied to battery so that fuel consumption reduces.
With continued reference to Fig. 5, it is shown that for controlling the air-flow of entrance electromotor during instantaneous state Program 500.Specifically, program 500 determines whether instantaneous state occurs and therefore, considering While the rotatory inertia of turbine, regulation enters the air-flow (such as, load) of engine cylinder. Such as, turbine can have sizable rotatory inertia, and the speed of turbine can be from air throttle When bypass valve cuts out, 0 rpm (RPM) under idle running and the highest load changes to Low to medium load more than 70000RPM.Therefore, the transient change of throttle position can not Change corresponding while causing air-flow.
In the 502 of program 500, determine engine operating condition.This operating mode can include engine speed, Engine load, air inlet flow rate and/or pressure, throttle position, accelerator pedal position, environment Pressure and ambient temperature etc..
After once operating mode determines, program 500 proceeds to 504, determines that instantaneous state is 504 No appearance.Such as, instantaneous state can change based on pinion ratio, air throttle or pedal position Relatively quick change, the change of turbine trip speed and/or the air-distributor pressure put or the change of air-flow And be identified.
If it is determined that there is not (such as, electromotor is under non-momentary state), journey in instantaneous state Sequence 500 proceeds to 506, utilizes based on from quality air stream at 506 air-flows entering electromotor First LOAD FOR of the measurement of quantity sensor determines.Such as, owing to instantaneous state not occurring, The air-flow measured corresponds directly to enter the air-flow of cylinder.Therefore, the first LOAD FOR can be based on By the mass air flow sensor being positioned in engine intake passage (such as above with reference to Fig. 1 institute The mass air flow sensor 120 described) Mass Air Flow measured.
On the other hand, if it is determined that instantaneous state occurs, program 500 proceeds to 508, 508 utilize the second LOAD FOR to determine the air-flow entering electromotor, and based on entering electromotor vapour The air-flow regulation operating parameters of cylinder.Such as, the air-flow (such as, load) entering cylinder can lead to Cross the second LOAD FOR to calculate, because delayed first loadometer caused due to turbine rotatory inertia Calculating may be inaccurate.
As an example, 510, the speed density calculated from Manifold Air Pressure can be used to Mass Air Flow is replaced to calculate this load.As another example, 512, load is permissible Time constant based on turbine.Such as, this time constant can be the function of parameter, this parameter example As by the pressure change of the air-flow of air throttle, air throttle, turbine trip speed and/or by auxiliary generator The electric current produced.In one example, the air-flow entering electromotor determines based on airflow model, The such as engine air flow calculation model 600 shown in Fig. 6.In such an example, by quality The air-flow that air flow sensor is measured is proportional 602.Such as, how much percentage ratio is determined Air-flow be transmitted through the air-flow of throttle bypass and how much percentage ratio and flow through air throttle.Such as, The air-flow percentage ratio transporting through throttle bypass based on throttle valve bypass valve can be opened and save Valve position and change.Equally, the percentage ratio of the air-flow flowing through air throttle can be based on air throttle by Logical valve open with throttle position and change.
It is as noted previously, as the rotatory inertia of turbine during instantaneous state, leaves the air-flow of turbine It is different from the air-flow entering throttle bypass.So, by the percentage ratio of the air-flow of throttle bypass, And the percentage ratio therefore flowing through the air-flow of turbine can be adjusted by turbine model 604.Whirlpool Wheel model 604 can include that the air-flow percentage ratio to including turbine time constant is applied one or more Individual filter.Such as, turbine model 604 can be the air-flow quantifying turbine during instantaneous state Delayed inertial model.In this way it is possible to determine and flow through throttle bypass and turbine and enter The flow of inlet manifold.
After application turbine model 604, the air-flow of regulation and by the air-flow percentage ratio of air throttle It is added 606, to determine the air-flow of the inlet manifold by air throttle downstream.Then manifold is filled Mold filling type 608 is applied to air-flow, to determine the air-flow (such as, load) entering engine cylinder. Manifold filling model 608 can depend on size and volume, the engine speed of such as inlet manifold Parameter with variable valve timing etc..
With continued reference to Fig. 5, after once calculating the air-flow entering cylinder, can be according to reality Air-flow regulates one or more operating parameters of such as fuel injection timing and/or fuel injection amount. For example, it is possible in response to the change of the air-flow caused due to the delay of turbine spin even faster or slow its rotation Change, regulate one or more operating parameters.In one example, respond the minimizing of air-flow and subtract Few fuel injection amount.The minimizing of air-flow is likely due to the increase of air throttle opening and in instantaneous state It is delayed that the air-flow that period causes due to turbine rotatory inertia changes.As another example, response Enter the minimizing of the air-flow of engine cylinder, postpone fuel injection timing.By this way, such as, During instantaneous operating mode, the accuracy of air/fuel ratio control can be improved and aerofluxus can be reduced Discharge.
In some instances, 514, based on air-flow the stable state of throttle position can be mapped and The pressure change of air throttle, regulates operating parameters.Such as, response is due to the rotatory inertia of turbine The minimizing of the air-flow by throttle bypass caused, throttle position can be regulated so that Make it farther during instantaneous operating mode and/or move quickly thus increase the air-flow by air throttle.Example As, after in view of the time constant of turbine, the throttle position of amendment can be based on conveying wink Time state during expectation air-flow (such as transient flow) required for the calculating of throttle position. By this way, such as, during instantaneous operating mode, the accuracy of conveying expectation moment of torsion can be improved, Thus, increase cornering ability/operating characteristics.
In some instances, such as (tip in) period is being tilted, when the bigger increasing requiring air-flow Added-time, throttle valve bypass valve can be closed.By this way, all inlet air flow are to engine cylinder Available, and delayed less than cause due to the rotatory inertia of turbocharger.
Therefore, during instant engine operating mode, one or more operating parameters can be regulated, So that improve electromotor running efficiency and/or exhaust emissions and/or operating characteristics.
Fig. 7 illustrates and illustrates the air-flow caused due to the rotatory inertia of turbine during instantaneous operating mode Delayed curve chart.Solid line 702 illustrates time dependent throttle position.As it can be seen, should Throttle position starts and at moment t in primary importance1And t2Between be opened to the second position.Real Line 704 is shown through the air throttle preferable air-flow to inlet manifold.Preferably air-flow is corresponding to joint Valve openings makes when air throttle opens (or close), the air-flow entering inlet manifold increase (or Reduce) amount of corresponding air throttle opening change.Dotted line 706 is shown through by air throttle and air throttle Road is to the actual air-flow of inlet manifold.As it can be seen, increase at air throttle opening and increase at air-flow The delayed of air-flow increase is there is between adding.Such as, until at moment t2The most just reaching afterwards To preferable air-flow.This is due to the such as rotatory inertia institute of turbine when the velocity variations of turbine Cause.
Fig. 8 illustrates the curve illustrating the throttle control above with reference to the amendment described by Fig. 5 Figure.Solid line 802 is shown in the throttle position (example of the time internal standard during instant engine operating mode As, by the throttle position shown in line 702 in Fig. 7).As the example shown in Fig. 7, joint Valve position starts and at moment t in primary importance1With moment t2Between be opened to the second position. Dotted line 804 illustrates the throttle position of amendment.As it can be seen, according to the throttle control of amendment, The amount that this air throttle is opened is more than at moment t1Start and at moment t3At the end of standard knot valve Amount.
Solid line 806 is shown in the system not including air throttle turbogenerator by corresponding to by line The air-flow of the air throttle of the throttle position shown in 802.White point line 808 is shown in and includes air throttle In the system of turbogenerator, such as above with reference in the engine system described by Fig. 1 instantaneous By the air-flow of air throttle during state.As it can be seen, by the air-flow of air throttle reach corresponding to At moment t3The air-flow of second section valve position, owing to being reduced by the air-flow of air throttle, the moment t3Compare t2Late.Dotted line 810 illustrates when the joint according to the amendment corresponding to throttle position line 804 By the air-flow of air throttle when valve controls to regulate throttle position.As it can be seen, by regulation Including the throttle position in the system of air throttle turbogenerator, during instantaneous state, pass through The air-flow of air throttle is substantially equal to the solar term in the system by not including air throttle turbogenerator The air-flow of door.
Therefore, it can execution program, such as above with reference to the program 500 described by Fig. 5, wherein Throttle control is modified to during instantaneous operating mode regulate throttle position.By this way, exist During instantaneous operating mode, can substantially keep identical by the air-flow of air throttle and expectation can be kept Moment of torsion.
