Further, in the low-angle and low pedal force scope of Das Gaspedal at GP1, motor/generator E-M/G uses as the driven by power motor, makes flywheel accelerate the speed that reaches predetermined by the signal control coupler.When equal angles and pedal force were in the GP2 scope in Das Gaspedal further reaches, elementary engine block OPOC1 started by the combination of ECC1 power-transfer clutch.The flywheel that rotates passes to bent axle CS1 to moment of torsion and starts elementary engine block OPOC1.Then elementary engine block OPOC1 drives flywheel and energy is passed to load.
Further, enter GP2 each time after the stage, ECC1 signal control coupler is closed.Motor/generator E-M/G and elementary engine block OPOC1 are used together by tandem, propulsive effort are provided for flywheel and change-speed box load by combination, and elementary engine block OPOC1 also can use separately.If elementary engine block OPOC1 uses with lower power, perhaps carry out transition period by the cold start-up requirement, motor/generator E-M/G replenishes in a limited time power is provided by in conjunction with coming and elementary engine block OPOC1 module series connection.On the other hand, when if elementary engine block OPOC1 uses with quite high power, hot machine state after perhaps using, when motor/generator E-M/G there is no need makeup energy is provided, then can be used as electrical generator or off line by the controller conversion, at this moment elementary engine block OPOC1 just makes unique propulsion source of vehicular drive.The design considerations that may also have other here is such as series-wound electric motor, by programme to assist charging in controller.
Further, when chaufeur is wanted to step on the juice, thereby can enter the GP3 stage by giving bigger pedal force of throttle pedal and the pedal angle being increased, ECC2 signal control coupler also can in conjunction with, also be combined with ECC1 signal control power-transfer clutch, secondary engine block OPOC2 is by the starting of the moment of torsion of bent axle CS2 and operation.Among the elementary engine block OPOC1 that secondary engine block OPOC2 has activated power input.In example, when needing maximum power, motor/generator E-M/G connects in the mode of series connection, and coming increases power for system.In addition, in the GP3 stage, elementary engine block OPOC1 and secondary engine block OPOC2 operate together as unit, and motor/generator charges the battery as an electrical generator.ECC2 signal control disconnect coupling when this state continuance is adjusted to Das Gaspedal power, secondary engine block OPOC2 is left unused and is shut down.
As shown in figure 14 a kind of hybrid power engine of the present invention system based on slow down and the brake situation under the diagram of curves of Das Gaspedal action control, the reference of describing among the embodiment " brake pedal " is as brake, input media perhaps slows down, also can be understood as other brake or deceleration input media, control lever for example, trace ball, handle, handle, CCS cruise control system, touch-screen and autobrake system also can provide similar functions.In this example, braking force is divided into two stages.When vehicle slides (BP0) when being applied to brake pedal with brakeless power; elementary engine block OPOC1 and secondary engine block OPOC2 are in and throw off and stopped status; vehicle mass inertia and flywheel inertia slide it, perhaps use a kind of sliding type change-speed box to come unidirectional rotation.When lower power is applied to brake pedal, be in first low-speed stage (BP1), have only electric regenerative brake to work, E-M/G is battery charge as an electrical generator.Braking regeneration is used, and makes car retardation by the change-speed box transmission.Need braking immediately, when the power that acts on brake pedal is increased to (BP2) when higher.Directly the machinery that is connected with wheel and hydraulic brake and braking energy reclaim and are used in the driving system.Certainly, can adopt the brake system of other types to substitute, for example: electric clipper control brake, the mechanical/hydraulic brake system, as long as they are available, also within the acceptable range, in other schemes, various variations in the BP2 scope also can use mechanical braking and regenerative brake to come battery is charged separately.
Further, the braking point " A " that chart shows in attached Figure 13 and 14, " B " and " C " is the multiple parameter that relies in the programming with the description of double end arrow.Such as, but be not limited to, external air temperature, air quality is measured, the oxygen level, highly, car load weight, car speed, engine temperature, engine speed, flywheel rotating speed, the flywheel temperature, road conditions (goes up a slope descending, smooth, coarse, smooth etc.), fuel performance, the selection of high fuel economy or drive performance, accumulator electric-quantity state.
Each operating chart under the different battery statuss of Figure 15 and a kind of hybrid power engine of the present invention shown in 16 system, system's various control element under given conditions namely works as the minimum and maximum critical level of battery charging state when combination and disengagement.Accompanying drawing 15 models provide when battery electric quantity near All Told Measurement 75% the time the control scheme.Accompanying drawing 16 models provide when battery electric quantity greatly about 30% or control scheme when lower.These two topmost difference of scheme are, when battery charge is low, before engine starting, E-M/G accelerates rotation with about 1000 rpms speed drive flywheel, start and continue to keep up to such as increasing battery charge at elementary engine block OPOC1, lower acceleration request just allows to be closed.This has one to describe breakpoint " A " " B " the design variation space relevant with " C " with accompanying drawing 13 and 14 before, between this Scheme Selection critical value 30% and 75% of battery electric quantity.
The simplified flow chart of the control operation of a kind of hybrid power engine of the present invention system as shown in figure 17.What this chart showed is the control logic of economic model, and this is used for hanging down Das Gaspedal acceleration when arriving moderate scope.If accelerator pedal angle increases greater than default critical level, control system will enter the aero mode that lowers category.When maximum power required, " motion " pattern may be provided.
Further, for better understanding the diagram of circuit in the accompanying drawing 17, the symbol that uses is defined as follows:
Table A
Table B
Table C
Table D
Further, when ignition lock is opened, start-up routine based on battery electric quantity state " SOC " according to the flow process of accompanying drawing 17 decide which should in conjunction with.Other factors, for example engine coolant and ambient air temperature can be used as additional factor.In this example, only considered state of charge.This is a cyclic program, in whole service stage of system and be not subjected to the restriction of initial start stage, carries out repeatedly with default circulation all the time.
Further, measuring state of charge during startup decides it whether to be in critical level.In this example, whether four critical level scopes are used to determine coupler to activate and disconnect, be combined as a motor use with E-M/G, when battery status reduces, kinetic energy is provided, when battery status is in constant, break away from E-M/G, perhaps make it become electrical generator by configuration E-M/G battery electric quantity state is increased.Under exacting terms, when state of charge is in 15% or when following, it is that battery slowly charges that system enters " careful charging " pattern.Careful charge mode is constant current and constant potential normally, but the speed of electric current be battery 1 times of ampere of capacity/hour.
Secondly further, state of charge determines preliminary flow process, and, (in this diagram of circuit, the Das Gaspedal of setting is different with the example in the accompanying drawing 13 with brake pedal position based on the power demand of Das Gaspedal (GP) and brake pedal (BP) locality specific.), GP3 here, GOP2b, GOP2a, GP1 and GP0 are the subintervals of the demand power that arranges of whole Das Gaspedal.Similarly, BP0, BP1and BP2 are the subintervals that brake pedal power is set.When module as the table B as described in together in conjunction with the time be implemented.From the diagram of circuit of accompanying drawing 17 as can be seen, higher greater than 90% o'clock at definite electric weight, the scope of various change-over points definition is wider in the intermediate range of 30%-90% than state of charge.This is because when state of charge is high, does not need battery charge.Yet, at zone line, may need charging, during except system requirements higher (GP3 and GP2b).Under different situations, filter comes work according to the height of demand earlier.Behind second filter, just determine coupler whether in conjunction with making power plant module provide power to vehicle.
The detail flowchart of the control operation of a kind of hybrid power engine of the present invention system has been strengthened the control of system shown in Figure 18 A-18Q, is not only by state of charge, and judges based on the nearest iteration of program.For describe the diagram of circuit of 18A-18Q and accompanying drawing 17 quadrature arrangement in the accompanying drawing continuously at the independent page.From accompanying drawing 18 as can be seen, screening is along top horizon state of charge, just as accompanying drawing 17 for the first time.Provided the single icon that how to detect setting, each state of charge screening decision, such as, accompanying drawing 18A state of charge is to be equal to, or greater than 90%, accompanying drawing 18B-18E is that second screening determines, so state of charge 90% screening has covered 18A-18E.The 30%-SOC-90% screening has covered accompanying drawing 18F-18L, and the 15%-SOC-30% screening has covered accompanying drawing 18M-18Q.
Further, in accompanying drawing 18A-18Q, each SOC screening determines to have second screening step, namely decides current power demand setting according to Das Gaspedal and brake pedal.Different with accompanying drawing 17 is, also has the 3rd screening (label " step 1-3 ") after second screening, and program judges by looking back to circulate what is to carry out immediately.Based on the decision of " step 1 ", another condition " step 2 " judges whether change any coupler and first stage motor, the combination of inferior stage motor and motor/generator system.
Further, for example, the indication that accompanying drawing 18 first screening washers adopt is that state of charge is 〉=90%, in this case, whether Das Gaspedal is defined in the maximum subinterval GP3 of setting, and itself and the Das Gaspedal that arranges are in the past compared, decide various coupler to be activated or disconnect.If the previous cycle is determined Das Gaspedal in the GP3 scope of demand is set, just do not use variation, coupler is in state of activation.All coupler and flywheel and change-speed box all are in state of activation and satisfy greatest requirements.Yet the demand Das Gaspedal is in default GP2 scope, and inferior stage motor is in off-line state (ECC2=0), so inferior stage motor need be activated (ECC2=1) in step 3, comes to provide for flywheel and vehicle the kinetic energy of annex.If the demand Das Gaspedal is in default GP1, GP0 or brake pedal BP0 scope, in other words, online be connected with coupler (E-M=1) of motor, if arranging before, GP0 or brake pedal BP0, in other words, the vehicle of circulation before is in and slides, flywheel and change-speed box disconnect, and have only the online and coupler of motor (E-M=1) to activate to keep the flywheel rotation.If in the subinterval that is preset in BP2 or BP1 of brake pedal, has only the online and coupler combination (E-G=1) of electrical generator in other words.In the subinterval of this greatest requirements state, preferential demand is littler than the GP2 setting, and this just has a transition.Electrical motor produces human discomfort with one of elementary or inferior stage motor in conjunction with providing power as much as possible immediately.Yet shown in step 2, first stage motor (ECC1=1) can be than the first combination of step 3, and the 3rd step time stage motor also can be in conjunction with controlled step conversion is provided.
Further, following " step 2 ", " step 3 " are final program iteration codes that arranges in table D.Use this " to recall " function, controller can avoid activating suddenly in the circulation indivedual coupler, and smooth transition is provided when speed requirement and brake.Accompanying drawing 18B-18Q has shown that equally various Das Gaspedals and brake pedal subinterval arrange demand, and the screening conditions of control.
The above is only for preferred embodiment of the present invention, is not so limits claim of the present invention, so the equivalent structure that all utilizations specification sheets of the present invention and diagramatic content are made changes, all is included in protection scope of the present invention.
