The invention further relates to a kind of method of controller motor-car starting period, described Motor Vehicle is by internal combustion engine drive and have an automatic clutch, at first internal-combustion engine by starter motor from static acceleration, from a predetermined critical speed, the engagement process of clutch is started, so that the beginning starting period, and start the injection process after the time in a segment sync.
The meaning of term " synchronously " is that motor control unit can be identified the absolute angle of I. C. engine crankshaft instantaneous position.This has comprised such information, that is, each cylinder alignment is in the part of which circulation.Usually use sensing system owing to adopting, be only possible this has only crossed several angle after bent axle rotates first after.
The invention still further relates to the method for starting vehicle internal combustion engine, the bent axle of internal-combustion engine links to each other with a drivetrain that comprises speed changer by at least one separable clutch, described drivetrain comprises at least one motor, preferably take I. C. engine crankshaft to a predefined initial rotation position by motor in the starting preparatory stage, during operation, the angular velocity of bent axle and angular orientation are determined by vehicle speed sensor.
The invention further relates to a kind of method that reduces the speed changer noise of vehicle drive train, internal-combustion engine is applied on a live axle and the motor, this motor is connected on the live axle by a cross box, and an activatable clutch is arranged between internal-combustion engine and the cross box.
Background technique
In order to satisfy following mobility requirement, Motor Vehicle must satisfy some additional requirements.In environmental policy is discussed, to pollute and interference that noise produces to special concern.As the result of international treaties, the legislator has stipulated severe reduction automobile CO 2Discharging and all oil consumption (Flottenverbrauch).
Except the target of environmental policy, also it should be noted that the demand of world market and vehicle user.The tendency that motor vehicle construction is comfortable and safe and circus caravan is arranged and the increase of the market share of so-called SUV (multifunctional movement automobile) causes the increase of vehicle weight is therefore so that reach oil consumption and emissions object becomes more difficult.The emotional factor of ignoring mobility fully also is impossible.Driving also is very important aspect, does not have the automobile of Driving to be difficult to sell to such an extent that go out.
To want on the one hand less oil consumption and discharging in order reaching, will to increase these conflicting targets of comfort level and handling on the other hand, must implement to comprise system's measure of whole drivetrain.
The more and more automation of the function of Motor Vehicle.This refers specifically to the set up procedure of Motor Vehicle.When a Motor Vehicle begins when mobile from static with the motor of idle running, cranking internal combustion engine at first, engaging clutch then is in order to produce positive engagement between internal-combustion engine and driving wheel.This cycle time is crucial, the time between the beginning that the beginning of its process starting process and Motor Vehicle accelerate.Whether the automatic system whether car steering person accepts depends primarily on it and manages to make the objective standard of time-delay, noise and flutter aspect to minimize and make the subjective criterion optimization.
In traditional system, internal-combustion engine is at first accelerated by starter motor and does not implement to spray, and to avoid discharging unburned hydrocarbons, makes the limiting value of waste gas deteriorated.Course of injection carried out after lock in time for the first time, and in stage lock in time, on the one hand, the phase place of piston and valve is in the zone that allows, and on the other hand, the enough height of the speed of motor are guaranteed abundant burning.From effectively spraying for the first time, can think that internal-combustion engine will provide a positive moment.Then the engagement process of clutch begins to start, and therefore, after the idle running time first time, moment can be delivered on the driving wheel of Motor Vehicle, and accelerating process begins.Until the whole endurance that Motor Vehicle begins to accelerate is depended on basically from the beginning of this process lock in time process during this period of time.Partly depend on during this period of time the output of starter motor, the rotary inertia of internal-combustion engine and friction torque, the required speed of lock in time and the internal-combustion engine phase place when this process starting.
Particularly can produce recoil momentum when the driving wheel of wheeled vehicle starts suddenly, this recoil momentum is exactly a vibration of making us bothering passenger's sensation.
EP0743216A2 has introduced a kind of hybrid vehicle, and it has an internal-combustion engine and an electric clutch motor also has an auxiliary motor.Starting process occurs by the electric clutch motor, and clutch motor and auxiliary motor are excited by following mode: the torque that acts on the live axle of driving wheel keeps constant.
U.S. Patent number 6244368B1 has introduced a kind of hybrid vehicle, and it has a motor and an internal-combustion engine.Under electric drive mode, when internal-combustion engine during by motor starting, its driving force is increased to the degree of the desired starting power of internal-combustion engine.
Starting and the driver element of internal combustion engine of motor vehicle can be known from DE19858992A1.Internal-combustion engine can be connected on the drivetrain that comprises cross box by a bent axle and clutch.Described cross box is connected with a motor, utilizes described motor can implement various starting methods.One starting cleansing phase is arranged before every kind of starting method, and bent axle is by electric machine rotation therebetween, and surveys starting conditions therebetween and clutch is closed, makes the decision of operational phase subsequently, and determines the start-up parameters of these operational phases.An electric start-control device is surveyed in the output of clutch and speed state and the speed process of input side by two velocity transducers that are arranged on the clutch both sides, start the starting method that the cleansing phase decision will be adopted at one, and determine its start-up parameters.
Velocity transducer judges that as a standard for example speed of crankshaft is relatively cheap, can only be a such shortcoming in position of determining bent axle more than the minimum speed in coarse mode but brought.Especially, in the situation that the bent axle slow-speed, velocity transducer just no longer can be used for having surveyed the position of bent axle.Even position transducer also can provide the accurate angle information of crank position again in the static situation of low speed or relative complex.
DE19808472A1 has introduced a kind of method for starter motor motor-car fuel injection type internal combustion engine.In time before igniting, motor is taken to a position by a drive unit low speed, on described position, the piston of a cylinder is parked on the top dead center, along with ignition order, motor is forced to carry out a further little rotation displacement, then sprays and lights a fire.The position of bent axle is surveyed by an independent crankshaft position sensor.
WO 01/88370A1 has introduced a kind of starting process and starter device of internal-combustion engine, and bent axle is by an electric machine rotation to a predetermined initial position.The position of bent axle is surveyed by an independent rotation that cooperates with bent axle and position transducer, and this position transducer is relatively expensive.
DE10062985A1 has introduced a kind of method and control gear of measuring the I. C. engine crankshaft angle, and internal-combustion engine and a motor are linked together, and its rotor is connected with the mode of bent axle with a kind of torsional rigid like this.Described motor comprises one to its control gear of controlling and a determining instrument, and this determining instrument is used for the angular orientation with respect to stator of rotor is measured.In order to measure crankshaft angles, control gear is surveyed and sent in the current angular orientation of rotor by the instrument that is used for the mensuration angular orientation.Then corresponding in real time crankshaft angles is determined on the basis of the angular orientation value that detects by control gear.Then, the crankshaft angles of measuring like this sends to the control unit of internal-combustion engine by control gear.
EP1113169A1 described a kind of internal-combustion engine starting arrangement and a kind of engine starting and stop process during control described starting arrangement method.Described starting arrangement has the electric drive system that a cover contains a motor, and described motor can link to each other with internal-combustion engine by a clutch.
Be known as starter generator (SSG) that sidepiece installs by a clutch during by internal combustion engine drive when one, one alternately momentum transmit by the transmission gear between motor and drivetrain, described alternately momentum is produced by the combustion stroke of internal-combustion engine.When a low generator momentum was fetched via described motor, the transmission momentum between internal-combustion engine and the motor can change that it is positive and negative.The flank of intervening gear is usually in the situation that require each other rigid support, and described flank can be separated from each other in possible play scope and again mutually collision, thereby can hear rattling sound.This situation occurs when low speed, particularly occurs when the racing speed of internal-combustion engine.
Summary of the invention
The objective of the invention is to make power transmission begin front shortest time by the control of optimizing starting period therefore also makes the acceleration of Motor Vehicle minimum.Another object of the present invention is to reduce at least the reaction momentum during impulse starting.A further object of the invention is the shortest time before the engagement of by the control of optimizing starting period, particularly optimizing clutch begins power transmission and therefore makes the acceleration of Motor Vehicle minimum.Another object of the present invention is the simplest enough possible mode to be positioned to be fit to the starting process to bent axle.Another object of the present invention is to avoid the click of gear-box, particularly in idling of IC engine.
Described purpose realizes according to the present invention in such a way, in the starting process internal-combustion engine when clutch is closed by motor driving, the clutch capacity of clutch reduces according to the parameter of at least one restriction at least, described parameter is motor speed, time, the torque of motor etc. of engine speed, the motor of internal-combustion engine preferably, preferably, automatic clutch is decontroled.
With the internal-combustion engine in the drivetrain of motor during starts, between driving machine and internal-combustion engine, carry out power transmission via clutch.According to present technical merit, clutch remains closed until reach a target velocity when internal-combustion engine accelerates process usually.Although described program can guarantee starting,, need the relatively long time, because only have a gear in the speed changer after this just to mesh, the actual movement of vehicle could begin like this.The method according to this invention can be saved time, and this is because even the cause that also can begin to declutch before burner oil begins.
Internal-combustion engine accelerates to obvious such speed greater than the desired minimum speed of starting process in advance.
According to described inventive concept, thereby can reduce time of starting period, thereby, compress into journey even before momentum is transferred on the internal-combustion engine by motor, also can start the pine of clutch, and internal-combustion engine is along with the sliding clutch that increases continuously is continued to accelerate.The drag torque of internal-combustion engine depends on the position of bent axle.The on the one hand transmission torque in order to grow as far as possible, on the other hand in order to let the clutch be slipped fast, the beginning of clutch process is arranged on a piston of internal-combustion engine through after the top dead center.The moment of decontroling can come to determine as follows:
1) by accurately measure the position of the angle of rotation of motor with the device that is called encoder, the absolute angle of described motor can both be read out if having time in institute.When having carried out calibration before between the encoder of the position transducer of internal-combustion engine and motor, this encoder can be used for drawing the conclusion of internal-combustion engine position.This synchronously or calibration finished by such mode: when clutch closure and crankshaft speed surpass in the situation of a predetermined minimum speed, at position transducer and synchronous for implementing between the device of Accurate Measurement motor rotary angle position, the latter is adjusted to the adaptation position transducer.
2) when the drag torque of the Assist force internal-combustion engine of motor, can derive from torque curve the top dead center position of piston.According to predetermined parameter, therefore can begin to open clutch through atdc at piston.
Before starting period began, all clutches in the drivetrain between internal-combustion engine and motor all were closed, had therefore produced being rotationally connected between motor and the internal-combustion engine.If motor is connected with driving wheel, then cut off such connection.Then motor is with the torque actuated internal-combustion engine of maximum.When reaching a predetermined speed, for example 500min -1, clutch capacity is reduced or just opening of automatic clutch begun behind top dead center position.Also beginning after clutch begins to open of the injection of fuel.When the injection process began, engine speed should be than a large at least 100min of critical velocity that can realize reliable starting process -1
For so that can mesh the first gear in a kind of very fast mode in automatic speed-changing system, the driving of motor is stopped using or of short duration counter-rotating after automatic clutch is opened.The part of the drivetrain of perhaps also can automatic transmission or linking to each other with automatic transmission is braked, and preferably retarding torque is provided by motor simultaneously.
After the starting process of internal-combustion engine, clutch meshes once again, and Motor Vehicle begins to accelerate simultaneously.After the starting process of internal-combustion engine, described internal-combustion engine provides very large torque, thereby the speed of increase oneself further makes Motor Vehicle accelerate on the other hand on the one hand.
The method according to this invention makes the reach of Motor Vehicle accelerating process, has therefore realized obviously faster response performance.
The invention further relates to a kind of device of controller motor-car starting period, described Motor Vehicle is equipped with an internal-combustion engine and an automatic clutch, described device is configured to trigger a motor so that internal-combustion engine accelerates from static the beginning, and described device further is arranged to trigger automatic clutch.This device has such feature according to the present invention: described device begins through the minimizing of atdc clutch torque with piston.Control device of electric motor according to the present invention has reduced described accelerating process and has begun the front time.
The invention further relates to a kind of Motor Vehicle, it has an internal-combustion engine and a motor, also has the automatic clutch in the drivetrain between internal-combustion engine and motor, and the control gear of control starting period.
In order to reduce recoil momentum in the impulse starting process, motor is by this way operation during the impulse starting process: the compensation that it is at least part of or reduce at least the recoil momentum of internal-combustion engine.Preferably, described impulse starting process preferably produces by driving wheel.
Mainly contain the possibility of two kinds of controls:
1) driving machine is accurately operated by the drag torque of internal-combustion engine.Clutch capacity is along with the torque of motor is transmitted accurately.If produce too fast or too high impact for the torque of transmitting motor, then this has caused the slip of convertible (schltbar) clutch, and as a result those impacts are cushioned.This method is suitable when the drag torque of internal-combustion engine can be fully by motor compensating.
2) when motor can not compensate whole drag torque of internal-combustion engine, it operates with an average torque.In order not allow any permanent slip of clutch, this torque must be enough high.Described clutch comes work with a capacity that all is equivalent in all cases described torque.Produce if impact by the cylinder compression, for example also high than clutch capacity, thereby this will cause the buffering of slip and the described impact of clutch.If produce than the little torque of described average drag torque, the momentum of internal-combustion engine just reduces thereupon.
For the shortest time before power transmission is begun, advantageously, be located at before lock in time the starting time of the engagement process of clutch.
The relevant discovery relevant with the present invention is, in the situation that each self-configuring of described system component, described engine speed is high more a lot of than the critical velocity that can successfully start process in lock in time.The method according to this invention, internal-combustion engine accelerate to the First Speed of the minimum speed that requires above the starting process at first in the situation that clutch has been opened an acceleration fully.As the corresponding result who then begins the clutch engagement, the Speed Reduction of internal-combustion engine, the simultaneously acceleration of Motor Vehicle begins.Control occurs by this way: in order successfully to finish the starting process, in the speed of lock in time still enough height.Like this, internal-combustion engine will provide an extra torque, increase on the one hand described speed, on the other hand further accelerating vehicle.The method according to this invention allows therefore the beginning in advance of the acceleration process of Motor Vehicle realized a response performance of obviously accelerating.
When the end of the engagement process of clutch is after lock in time, can realize especially stably starting performance.Therefore, when clutch still has certain slip, realized the igniting first time of internal-combustion engine, thereby most of torque shock ends absorbed by clutch at this moment still.
One of the method according to this invention embodiment particularly preferably, the zero hour of starting period clutch open, in other words, when internal-combustion engine is static, open.Described clutch also can be closed in the zero hour of starting period, in other words, speed changer static at internal-combustion engine and Motor Vehicle can be closed when neutral, therefore clutch is opened at very first time point, engaged at gear of the second time point, engagement process at the 3rd time point clutch begins, and then begins in a synchronous time injection process.This distortion of described method also is favourable, even in the long-time quiescent period, also will not remain on open mode by clutch.
Particularly preferably be that when the injection process began, engine speed was than a large at least 100min of critical velocity that can realize reliable starting process -1Can guarantee so the reliable starting process under all operating conditions.
The invention further relates to the device of controller motor-car starting period, described Motor Vehicle is equipped with an internal-combustion engine and an automatic clutch, and this device is configured to trigger starter motor, so that from static acceleration internal-combustion engine, being configured to start the engagement process of clutch, so that beginning starting period and begin course of injection in lock in time.Described device has following feature according to the present invention: described device determines that the beginning of engagement time of clutch is prior to described lock in time.Engine controlling unit according to the present invention has reduced the acceleration process and has begun the front time.
The invention further relates to a kind of Motor Vehicle, it has an internal-combustion engine, the control gear of automatic clutch and the described starting period of control.The present invention can be applied to be equipped with in particularly advantageous mode the Motor Vehicle of a starter generator.Being connected in the drivetrain is a motor, and this motor can be used as starter motor and generator simultaneously.
In order to determine best lock in time, particularly preferably be that the device that is used for the control starting period is connected to camshaft-signal sensor and crankshaft sensor simultaneously.Can determine reliably like this at which cylinder to occur to spray for the first time and igniting.
When being set to automatic transmission, the speed changer of Motor Vehicle can obtain special advantage.Particularly advantageous when speed changer is set to continuously variable transmission.As mentioned above, the starting process can be carried out by this way,, does not need any intervention of driver that is, in this case, at first adopts a closed clutch, and it at first is opened, in order to mesh a gear, then carries out actual engagement process.According to an embodiment particularly preferably of the present invention, Motor Vehicle is equipped with an automatic parking brake device, the control coupling of itself and starting period.Such automatic parking braking device is the second braking device, and it starts in the time of stationary vehicle, and continuous firing is until be applied to enough torques on the drivetrain in order to start the acceleration process.With a such automatic parking brake device, the driver does not need to take any special measure, just can start to walk on the road surface that tilts easily.
In order to satisfy various load-up conditions during starts, an inclination sensor can suitably be provided, its device with the control starting period links to each other.Described inclination sensor is at the inclined degree of vertically measuring car body, can determine optionally that like this a starting process must carry out upward slope.
The load condition of further being correlated with that when the Motor Vehicle heavy duty, provides.In this case, after the engagement process of clutch begins, must wish a stronger braking of internal-combustion engine, therefore mesh the beginning of process and must be postponed a little.This situation can be by relatively coming present engine torque and the torque phase that precomputes to determine, it is state unloaded and that just be moved except the driver that the torque that precomputes represents vehicle.Described torque can from the clutch engagement, be determined by the decline situation of engine speed.Because on the road, the load of vehicle is constant or change seldom, and the previous value of measuring can be used as an estimated value, until determined new numerical value.
Special advantage according to solution of the present invention obtains in the vehicle that is equipped with automatic starting one halt system.Automatic starting one halt system like this is static or close internal-combustion engine when not needing torque at Motor Vehicle, and is detecting automatic cranking internal combustion engine when needing accordingly there from the driver.
When the device that has for the rotary angle position that accurately detects motor, can obtain the position of the bent axle of the process of starting, when engine speed sensor when clutch closure and crankshaft speed are on a predetermined minimum speed be used for having carried out synchronously between the device of rotary angle position of Accurate Measurement motor, described rotary angle position is adjusted to the adaptation engine speed sensor, checks and control the setting of initial rotational position behind synchronized process by means of the device of the rotary angle position that is used for the mensuration motor.
The device that is used for the Accurate Measurement rotational position sometimes is used as standard fitting at motor.They can be by independent position transducers or also can be formed by the non-sensor, method of the rotary angle position of measuring motor.
In the method according to the invention, in order to measure accurate rotary crankshaft position at the dwell period of internal-combustion engine, and monitor accurate rotary crankshaft position in the starting preparatory stage, used the device of the rotational position of Accurate Measurement motor.Therefore just do not need other additional exact position sensors.
Can be arranged to like this, that is, make it to be in initial position by the motor driving bent axle, perhaps preferably make it to be in initial position by the motor braking bent axle.
The click of speed changer during for fear of idling of IC engine, can be according to the state in the cross box, that namely stretch or axial load, control in this wise torque in the drivetrain by the interaction effect of convertible clutch: namely suppress to drive vibration, and clutch is preferably driven by a clutch torque, its torque peak than the driving torque of internal-combustion engine is low, and described engine torque rises and falls in a looping fashion.Clutch capacity is directed into the average torque slightly higher than motor.
The reverse of torque mainly occurs in compression procedure, the bent axle braking that causes motor not follow, and this is because inertia and the low result who produces torque.
If the capacity movable of clutch becomes the generation torque slightly higher than motor, clutch is owing to compression cycle and maximization transmission clutch capacity, in the situation that the bent axle braking will begin slip, even in the other direction.In burning was afterwards impacted, when the torque ratio clutch capacity that produces was large, clutch still can slide.Existing method can not be avoided cutting stage lax between internal-combustion engine and the motor.Because the difference between maximum forward and the maximum reverse torque is little, the bump the when flank of tooth meets is subdued effectively, has therefore effectively avoided the click of speed changer.
When clutch capacity is reduced during compression procedure, obtained further raising, it is the most idealized to be to reach null value, because like this, the difference between maximum forward above-mentioned and the maximum reverse torque value is further reduced.

Embodiment
Reduce oil consumption and discharging in order to reach predefined target, to comprise, also comprise comfort level that part is conflicting and handling, must be by by the system's measure that comprises that whole drivetrain forms.Fig. 1 and 2 shows such hybrid drive train that is used for small-sized and compact car, and it can reach above-mentioned target.Fig. 1 shows the overall structure of hybrid electric drive system 10.The main driving source of drivetrain 11 is an internal-combustion engine 12 (for example diesel engine), it is less that this internal-combustion engine is compared basic motive (Basismotorisierung), and this internal-combustion engine is by automatic transmission 14 couplings of automatic clutch 50 with for example six gears.A motor 16 links to each other with automatic transmission 14 via cross box 18 by convertible clutch 50a, 50b (for example convertible timing clutch).Described motor 16 can be used as generator and motor simultaneously, this motor 16 has the approximately peak value power of lasting 5 seconds the 25kW of lasting motive force peace treaty of 10kW in described embodiment, and the high-power electronic device (Leistungselektronik) that is comprised of the battery pack 22 with 12 volts of voltages and the double layer capacitor 24 with 42 volts of voltages triggers.Cross box 18 can be by motor 16 switch on the one hand with live axle 30 couplings of automatic transmission 14, on the other hand with output shaft 32 couplings of automatic transmission 14.Described output shaft 32 guiding driving wheels 34.Compare with the layout on the bent axle that motor 16 is placed in internal-combustion engine 12, hybrid drive system 10 of the present invention has advantages of that the whole length of automatic transmission 14 does not require at the clutch region extension, and this application that motor is laterally installed forwardly is even more important.The motor 16 of described hybrid drive train 10 is independent, intrinsic unit optimized, and is irrelevant with automatic transmission 14.Be located in the system on the bent axle, especially difficult to the optimization in the space between stator (being positioned on the mission case) and the rotor (being positioned on the bent axle) in the asynchronous motor situation, thus cause sometimes loss in efficiency.
Be bolted on the cross box 18 by the high-power electronic device 20 that processor 26, transducer 28 and direct current-direct current transducer (referring to Fig. 4) forms.The double layer capacitor 24 that is used as energy storage device is arranged on above the automatic transmission 14 and is fixed on (referring to Fig. 2) on the car body.The cooling of high-power electronic device 20 and motor 16 is directly unified in the cool cycles of internal-combustion engine 12.
Described motor 16 can be used as starter motor and generator simultaneously, and therefore, these two assemblies can be omitted.In addition, braking force can reclaim (compensation) by motor 16, and described internal-combustion engine 12 is coupled with its friction horsepower, in the situation that system is installed in crankshaft side, this can only realize by a second clutch.
The another one importance of described hybrid electric drive system 10 is that the tractive force that motor 16 can be filled up when shifting of transmission interrupts, so that very smooth and easy during automatic transmission 14 gear shift.The gear shift comfort level that this causes the gear shift comfort level with the automatic frequency-conversion speed changer to be close.
Select double layer capacitor 24 rather than 42V battery, this allows to make motor 16 to have very high electric current as motor and generating function in the short time simultaneously.This provides when providing tractive force during speed-raising and gear shift and in the advantage of capacitor between convalescence.The energy Ratios battery that double layer capacitor 24 stores will lack, and it is better therefore not requiring motor 16 that the electric functions of long electric motor operated is provided.Therefore the strategy of energy management is designed to require that double layer capacitor 24 provides as much as possible, short loading and unloading circulation, and double layer capacitor 24 also is fit to such purpose.
The structure of described electrical system as shown in Figure 4.Except motor 16, for electric water pump 36 provides 42V voltage.It also is possible providing electric power for other electrical assembly (air condition compressor, variable valve regulating device etc.).Described control unit is connected on the control network of vehicle via control unit connection set 38, the information that 38 guidings of control unit connection set are necessary and instruction are to the control network 42 of interior hybrid drive train, and described drivetrain links to each other with transmission control unit TCU with control unit of engine ECU.Communicate with high-power electronic device 20 by the special-purpose CAN of what is called (control area net（CAN）), high-power electronic device 20 comprises processor 26, transducer 28 and direct current-direct current transducer 29, and special-purpose CAN is by reference character 44 expressions.The control network 40 of vehicle and the control network 42 of drivetrain can be set to the CAN bus system.
Under existing conditions, internal-combustion engine 12 is set to three cylinder type diesel engines, and each cylinder has two valves, and cross-current type cylinder head scheme and variable eddy-current system.Internal-combustion engine 12 has: a usual pressure track ejecting system; One gas recirculation system, this system has cooler and electric exhaust gas recirculation valve; One electric water pump; One electric constant-temp regulator valve.The variable turbine geometry is provided as load concept (Aufladekonzept).
Reference character 46 expression 12V networks among Fig. 4, reference character 48 expression 42V networks.
Quite high engine load in having for example driving pattern (for example NEDC one new European driving pattern) that has improved respectively internal-combustion engine 12 thermodynamic efficiencies can be adjusted by volume mode and automatic transmission 14 acquisitions of load transfer (Lastenverschiebung durch Hubraumanpassung).Yet the higher load of generation has caused more difficult about NO xThe boundary conditions of discharging.Yet, NO xDischarging can reduce by optimizing the relative combustion parameter basically, and said parameter is piston groove for example, compression, the nozzle specification, nozzle projection, AGR ratio, air inlet activity (whirlpool) and the jet pressure under the boundary conditions of high specific engines load separately and spray starting point.
Fig. 3 has shown the concise and to the point layout of automatic transmission 14 and cross box 18.Forward gears gear 1 to 6 o'clock is synchronous, and reverse gear R is set to a sliding gear.
Clutch 50 is encouraged by an electric driving clutch actuator by a release lever.The gear shift of speed changer also produces in electronic mode.Two gear selector drums are encouraged respectively by two gear carriers (Zahnradstufen), and therefore, described gear can be engaged and break away from.A gear selector drum interrelates with reverse gear and 2,4 grades of gears, and another then contacts with gear 1,3,5 and 6.This shift strategy has guaranteed the very short speed-change and gearshift time.Because adjacent gear is on the different gear selector drums, by breaking away from simultaneously initial gear and engagement target gear, can obtain the very short shifting of transmission time, this former is possible by being only with hydraulic transmission.Even numbers gear shift (for example from 5 to 3) can occur very fast, because do not need to mesh an intermediate gear.
The coupling of described motor 16 and automatic transmission 14 produces by cross box 18.Kinetic current moves on the jack shaft 52 through two cylindrical gear pairs (Stirnradstufen) (gear pair (Stufe) S4 and S3) from motor 16, is equipped with the change wheel 54,56 of gear pair S2 and gear pair S1 on this jack shaft.This two change wheel 54,56 can by the conversion of the gear selector of gear R/2/4 drum, therefore, so just not need other exciter system.Gear pair S2 links to each other with motor 16 via the fourth speed gear 58 on the live axle 30.Internal-combustion engine 12 for example can be in this shift pattern starting.Gear pair S1 connects motor 16 and output shaft 31, thereby allows the result who advances, namely drives of short duration output peak value to allow.Because motor 16 can reach for example 20000min -1Rotating speed, thereby, must pay special attention to the configuration of gear, the structure of particularly gear pair S4, and bearing and sleeve pipe.
Motor 16 and high-power electronic device 20 are connected to described cross box 18 in present example, high-power electronic device 20 is included in processor 26, direct current one direct current electric transducer 29 and the transducer 28 in the housing.This has caused very compact layout, and caused on the one hand being used for guide current and for the very short path that the electric wire between motor 16 and the high-power electronic device 20 is cooled off, having caused on the other hand the adjacent component of double layer capacitor 24 and the short path between the engine cooling apparatus.The configuration of electrical system and interface as shown in Figure 5.
Strong asynchronous motor for example is fit to reach the requirement on the motor 16.Directly link in the cool cycles of internal-combustion engine 12 via a bypass about the frequency converter 28 that the cooling aspect is crucial especially.Only have after this, freezing mixture is directed into the more unessential motor 16 in hot aspect.Therefore, cooling and compact arrangement are the important requirements to transducer 28.Direct current one direct current electric transducer 29 power supply network 46 on the network 48 and 12V car that is used for being coupled on the 42V car.It mainly serves as the task of generator.As the result of compact arrangement, a simple topology can be implemented.Owing to generally not having the 42V network in present vehicle concept, present idea provides the simple possibility of the vehicle family of an expansion existence for the high consumer of demand motive force by a high voltage bus.It is local that described 42V network 48 also can be limited to motor 16 zones.So only be used for transducer 28 and the energy accumulator of being coupled.Sensing system 60 and diagnose interface 62 (for example RS-232) have replenished power-actuated characteristic curve.Diagnose interface 62 and special-purpose CAN44 can embed connector 63 or terminal 15/30/CAN links to each other by vehicle.
Compare with traditional drivetrain, motor 16 is integrated into provides following additional function in the described hybrid electric drive system 10:
The peace and quiet of-internal-combustion engine 12, the starting that quick and reduction is discharged,
-generator operation is powered to 12V and 42V In-vehicle networking on the car,
-recover (by electrodynamic or the internal-combustion engine braking energy recovery that emulation provides of thrusting),
-along with the quiet quick starting of motor is flame-out during idle running (play one and stop function),
-the gear shift that has tractive force to support,
-electricity starting support,
-accelerate to advance,
-impulse starting.
Described topological structure mainly allows electricity to drive and slides.Yet these functions are also limited by energy storage device.
Vehicle for a long time static (for example in the traffic lights front) and enable foot brake in, have clear and definite advantage aspect the consumption on driving pattern of stopping working of internal-combustion engine 12.The resolute acceptance of flame-out function is the of short duration reaction time that internal-combustion engine 12 is reset when idle running.This means that internal-combustion engine must start between the action of the loosening and gas pedal that brakes, like this, vehicle will begin mobile, and not have common delay in this case.Begin to reset by the minimizing of brake pressure or the small loosening up of braking pedal, so motor 16 accelerates internal-combustion engine 12.Then, initial gear is engaged, so cause the positive engagement with driving wheel.
In hybrid electric drive system 10 of the present invention, use very expeditiously an automatic transmission 14, can also pass through freely selecting of shift point, help in the automatic mode driving cycle, to reduce oil consumption.Simultaneously, by manual mode, also provide motility to make things convenient for the possibility of gear shift to the driver.More automatically change speed changer, unique shortcoming of such speed changer configuration is the short interruption of tractive force.This hybrid electric drive system 10 provides now when described tractive force minibreak and has driven the possibility of vehicle by motor 16, thereby can carry out very easily gear shift.When at the full and down gear up, the tractive force support according to gear and engine speed between 30% and 100%.This means that the tractive force when gear shift can be up in 100% of gear shift rear haulage power.Particularly from 1 to 2 with from 2 during to 3 gear shift, it is very important when considering the gear shift comfortable feel of automatic transmission, and the tractive force support is than whole velocity ranges taller 50% of internal-combustion engine.
The target of propulsion functions is to improve power character and the mobility of vehicle.Fig. 6 shows internal-combustion engine 12, motor 16 and obtainable total torque M GTorque characteristic curve.The torque of internal-combustion engine 12 is M B, the torque M of motor 16 EExpression.Torque M is illustrated on the speed n.
Move away and be even more important for the mobility of driving with first grade of acceleration, it also is applicable to particularly the spontaneity at high tap position.Fig. 6 shows the torque M of motivational drive motor 16 (ongoing operation) schematically eCurve, in addition the torque characteristic curve M of internal-combustion engine 12 B, and the motor on the output shaft 32 16 obtainable total torque M in the time of 5 grades GAs shown in the figure, the total torque M corresponding with the maximum power of internal-combustion engine 12 GCan in the situation that idling speed provide.By short overload motor 16, be possible to the such curve of all gear analyses.Owing to adopting native system, can not advance in any random time, the restriction of effective coverage then must be provided.When the driver required a corresponding output by an accelerator pedal, the speed of propulsion functions from starting to the maximum engine torque was (in the present embodiment near 2000min -1) be available.For fear of the overload speed changer, from the total torque M of internal-combustion engine 12 and motor 16 GCan be restricted to the maximum power M of internal-combustion engine 12 BThis provides power character in operating range to vehicle, and feature is so-called " turbine bore ", therefore is particularly conducive to approval and Driving.Because it is very fast that these velocity ranges (particularly in low grade) slip over, the power that requires from double layer capacitor 24 for this purpose is still in boundary.
Described propulsion functions also provides again consumption and compensation power, and this will be described in detail below.
In the NEDC driving cycle of testing in the present embodiment, the total energy consumption with vehicle of hybrid electric drive system 10 approximately is 4.3MJ.Approximately 1.3MJ loses during braking.This has represented whole cycle braking energy recovery and energy-conservation theoretical potential.The target of intelligence energy management is to utilize these brake losses by the braking that recovers as much as possible, and can again put into these brake losses in the operating process of vehicle in a kind of useful mode.Consider the boundary conditions of " the maximum output of motor " and " the maximum voltage skew of energy accumulator ", during the NEDC driving cycle, can obtain about 410kJ.This value has also been considered the usability of energy management in the driving operation of reality.The loading of energy accumulator and be discharged in the NEDC driving cycle and can accurately be scheduled to.When next section is wished a loading cycle, can receive a low-down energy level over a long time like this.In the driving operation of reality, lack this knowledge.Why Here it is must guarantee that energy accumulator always keeps a minimum energy deposit, and for example guarantee the gear shift that the tractive force support is arranged can obtain if having time sufficient energy reserve.This means the reduction of maximum voltage skew, therefore be reduced to about 410kJ at the NEDC driving cycle recovering potential.
Energy storage in order to ensure storage is coincide before and after the NEDC driving cycle, and the energy demand that compensates consumes during driving cycle.When considering whole efficiency chain, simple parallel is nonsensical in internal-combustion engine 12 operating electrical machines 16.Analysis to the NEDC driving cycle has shown of short duration high load(ing) point, yet it has caused CO basically 2And NO xTherefore, in these special scopes (propelling), support 12 selection strategy of internal-combustion engines to be inevitable with motor 16.
Fig. 7 has shown in the part of NEDC driving pattern, the torque M of internal-combustion engine 12 and motor 16 B, M ESummation.More clear for what explain, tractive force is left in the basket during being supported in gear shift.Fig. 8 has shown the response curve of the speed n of internal-combustion engine 12.
Fig. 9 and 10 has shown CO 2And NO xThe savings potential of discharging.The energy input that motor 16 is supported is 393KJ, as a result energy accumulator basic complete equilibrium before and after driving cycle.Present strategy can make NO xDischarging is minimizing 15% and CO approximately 2Discharging approximately reduces 9%.Curve V oAnd N oThe consumption and the NO that do not have motor 16 to support have been shown xDischarging, curve V uAnd N uShown and had consumption V and the NO that motor 16 is supported xDischarging.
Along with the movement of described brake petal, begun the quick starting of motor, thereby begun the starting command of the renewal starting of internal-combustion engine 12.Almost simultaneously, the torque of motor 16 accumulation beginning, internal-combustion engine is accelerated as a result.As long as the first gear is engaged, drive and prepare just to have carried out, then, utilize motor 16 just can drive away their vehicles.Figure 11 has shown internal-combustion engine 12 in the quick starting of rise-stopping between functional period, the speed n of motor 16 ESpeed n with internal-combustion engine 12 BT is plotted in the time.The place sends starting command at the S point.The first gear is in the T point gearing, and torque can be transferred on the driving wheel.Line G has shown shelves levels (Gangstufe), and in this case, shelves levels " 9 " have signified the neutral position.
Figure 12 shows the engine speed n when having motor 16 to support BCurve with the acceleration a of vehicle (calculating by record wheel speed at the cylinder Laboratory Furniture).Accompanying drawing 13 shows the engine speed n when not having motor 16 to support BCurve with the acceleration a of vehicle.Do not have electrodynamic support, (acceleration a becomes negative) produced typical tractive force interruption during gear shift.The help of motor 16 has been arranged, the interruption that has replenished tractive force of a lasting forward torque and part just may be provided.
In order to save fuel oil, internal-combustion engine can stop working under the specific vehicle state.When the vehicle-state change, internal-combustion engine starts again, and it also must be possible in the vehicle of a movement.A pulse that is set to the motor 16 of a starter generator can be used for hybrid electric drive system 10, in order to accelerate the pulse of internal-combustion engine 12 and driving wheel 34.A device that is arranged in speed changer 14 is essential, and this device is used for motor 16 is coupled to the speed changer input end, can be only uses before this device reaching one that limit, relatively low car speed (first grade).Therefore internal-combustion engine 12 directly can guarantee on the vehicle of a movement via motor 16 startings.When motor 16 and speed changer output terminal are coupled, can in the whole velocity range of vehicle, work via the starting of the pulse of driving wheel 34.Yet, can produce in this case a counter torque, it can be experienced by Vehicular occupant by the form of the impact making us bothering.
This counter torque can be by using motor 16 to compensate in the usefulness scope of motor 16 or weakening.
1) motor 16 is with the drag torque M of internal-combustion engine 12 SAccurately operated.Therefore, the clutch capacity M of clutch 50 KAccurately follow the torque M of motivational drive motor 16 EIf in order to adjust the torque M of motor 16 EAnd too fast or too high vibration occurs suddenly, and so, this will cause the slip of clutch 50, and result's vibration is cushioned.Drag torque M when internal-combustion engine 12 sIn the time of can being compensated by motor 16 fully, this method is fit to.
2) if motor 16 can not compensate whole drag torque M of internal-combustion engine 12 S, it will be to be equivalent to average drag torque M mTorque M EOperate, in order to guarantee that clutch 50 does not continue to slide described torque M EMust be enough large.Clutch 50 is with capacity M KOperate, its also with described average drag torque M mQuite.Produced by the cylinder compression if vibration is moving, for example it is than clutch capacity M KTo cause greatly, so like this slip of clutch 50 to cushion described vibration.If the average drag torque M of torque ratio that produces mLittle, the torque of motor 16 will correspondingly reduce.
In the starting of the internal-combustion engine 12 in hybrid electric drive system 10, power transmission produces between motor 16 and internal-combustion engine 12 via clutch 50.According to present technical merit, internal-combustion engine 12 will be accelerated until reach target velocity, and clutch 50 is closed.Although this provides safe driving, it needs one period considerable time.
This time can by in addition begin to open clutch 50 and continue to make internal-combustion engine 12 to accelerate to shorten by sliding along with the gradually increase of clutch 50 during just by motor 16 transmission when a torque.The drag torque of internal-combustion engine 12 depends on the position of bent axle.In order to transmit as far as possible for a long time torque on the one hand, open rapidly on the other hand clutch 50, a top dead center that begins to be moved to internal-combustion engine 12 of clutch process.Therefore, opening torque can decide by following dual mode:
1) by coming the rotary angle position of Accurate Measurement motor 16 with a kind of device that is called encoder, the absolute angle that just can read at any time motor 16.When having carried out calibration between the encoder of the position transducer of combustion motor 12 before and motor 16, this encoder can be used to draw the conclusion of the position of combustion motor 12.The calibration of carrying out between the encoder of the position transducer of this combustion motor 12 and motor 16 is carried out by this way: the closed and crankshaft speed when clutch 50 is in the situation that one be scheduled on the minimum speed, implement a synchronously operation between the encoder of the position transducer of internal-combustion engine 12 and motor 16, the latter is adjusted to the adaptation position transducer.
2) when the torque M of motor 16 eFollow the drag torque M of internal-combustion engine 12 sThe time, can be from the torque curve M of motor 16 EThe top dead center position of middle derivation piston.
The plotted curve of Figure 16 has shown the engine speed n on time t.When time t=0, internal-combustion engine is in state of rest, supposes in case during the corresponding requirements that for example shows in the mode of bend the throttle that detects that the driver sends, just send cranking internal combustion engine and drive the signal that leaves.The speed n of internal-combustion engine 101 is along with the starting of starter motor begins to increase.In case reach a predetermined speed n 1, clutch 102 begins engagement, and begins torque transfer to driving wheel 104.A driving torque is transferred on the wheel 102 from internal-combustion engine 101 via sliding clutch 102.The speed n of internal-combustion engine 101 is by the last value of the being reduced to n of torque transfer 2, but an appropriate device of its driven system control remains on and is the selected level of starting period.Value n 2To always be in minimum speed n MinOn, and generally always on idling speed.Assurance is by the predictability of system behavio(u)r, and described value can not drop on minimum speed n MinUnder.
Be injected in for the first time time t sBeginning, it is in time t SvncMore afterwards, so internal-combustion engine 101 begins to provide forward torque.The engagement process of clutch 102 is at time t EeFinish, it is in time t SyncAfterwards, so a direct power transmission has produced.
The embodiment of the method for Figure 17 is different in these places from Figure 16: clutch is engaged until time t at first 1Speed changer is in neutral position, so there is not power transmission.Clutch is at time t 1And t 2Between open, so can give a control command to automatic transmission, allow this automatic transmission remove to mesh first gear.From time t EsBeginning, the power formula of described method simulation Figure 16 is carried out.
Curve under the t-n of Figure 17 figure shows the course of action of clutch, and o represents open mode, and e represents engagement.
Figure 18 has schematically shown the chief component according to the drivetrain of the Motor Vehicle of first embodiment of the invention.An internal-combustion engine 101 links to each other with automatic transmission 103 via an automatic clutch 102.Described speed changer 103 drives driving wheel (here with 104 schematically show) via a drivetrain (representing with reference character 110) here.A bent axle starter generator 109 is provided in the upstream of clutch 102, and described generator is used especially for cranking internal combustion engine 101.Another clutch 112 selectively is provided between internal-combustion engine 101 and the bent axle starter generator 109, thereby allows the pure electric operating of vehicle.This embodiment is fit to simultaneously according to the method for Figure 16 with according to the method for Figure 17.
In the embodiment of Figure 19, starter generator 109 is set in parallel with speed changer 103.First tape drive 105 is arranged on the upstream of speed changer 103, and second tape drive 106 is arranged on the downstream of speed changer 103.Tape drive 105 links to each other with motor 109 with 108 via clutch 107 with 106, and described motor is used as a starter generator.Under the corresponding configuration of speed changer 103, also may be set to clutch 107 and 108 synchronizing ring or substitute them with synchronizing ring.
Because clutch 102 is arranged on the upstream of tape drive 105, thereby, only have the method according to Figure 17 can be suitable for such embodiment.By at time t 2Open clutch 102, the torque transfer from starter generator 109 to internal-combustion engine is interrupted, so speed n is at time t 2After begin to descend.
To one skilled in the art, obviously, by corresponding change, also may come with a similar embodiment method of executive basis Figure 16.
Figure 20 shows an internal-combustion engine 201, and it is connected to a drivetrain 204 via a bent axle 202 and a convertible clutch 203, is provided with a speed changer 205 in drivetrain 204.A motor 206 selectively is connected with speed changer 205, and described motor selectively is operably connected to transmission input shaft 210 or transmission output shaft 207.Internal-combustion engine 201, clutch 203, speed changer 205 and motor 206 such being arranged in the motor vehicle driven by mixed power are often used.
In order to monitor the speed of bent axle 202, a velocity transducer 208 for example is arranged on the zone of flywheel, and described sensor can only transfer the rotational position of detection bent axle 202 from a predetermined minimum speed, for example per minute 100 of bent axle 202.
Provide a pinpoint accuracy position transducer 209 or one without sensor, method, detected or monitored the exact position of the angle of swing of motor 206.Therefore, the position of described angle of swing can be measured with the validity of about 0.5 ° degree in crank angle.Such position transducer or without sensor, method in being set to the motor of polyphase machine as a kind of standard application.
For can quick starting after internal-combustion engine 201 is flame-out, in the starting preparatory stage, bent axle 202 be brought to a predetermined initial rotational position.Because before injection and fire fuel, bent axle 202 just is brought to an accurate predetermined start rotational position, so on the one hand the electronics of motor can Fast synchronization, internal-combustion engine can be optimized starting on the other hand, in order to fast as far as possible overcome for the first time compression stage.In order to realize these, the method according to this invention, the position of the angle of swing of bent axle 202 monitors by the position transducer 209 of motor 206 or without sensor, method, to measure the position of angle of swing.Yet precondition is before this, adjust described position transducer 209 or described without sensor, method to adapt to this crank position.This is carried out by velocity transducer 208, and this velocity transducer is as a standard of measuring crankshaft speed.Check in the first step whether clutch 203 is closed.If not, bring such state and bring bent axle 202 and drivetrain 204 and motor 206 between rigid rotating connect, cut off described drivetrain from driving wheel simultaneously.Whether the speed that also will check bent axle 202 is on the minimum speed, and velocity transducer 208 can be used to measure described position like this.When these two preconditions are satisfied (clutch 203 speed closed and bent axle 202 are higher than minimum speed), position transducer 209 or be adjusted to speed-adaptive sensor 28 without sensor, method, thus finish synchronous.This process is only required fractions of a second up to a few seconds, can and carry out during the coasting after internal-combustion engine 201 stops working.
In the starting preparatory stage, it can carried out near prestart after stopping working or only, and under the help of motor 206 and position transducer 209, bent axle 202 is brought to the predetermined start rotational position.This can be by effective driving of 206 pairs of bent axles 202 of motor, perhaps particularly after internal-combustion engine 201 stops working, by particularly occuring to the predetermined start position in a lower bent axle 202 brakings of the help of motor 206.
Therefore, in the situation of the exact position sensor that need not to add, the initial ready position of pinpoint accuracy of a bent axle 202 and very fast starting process can be arranged also.
Figure 21 shows a drivetrain 310 with an internal-combustion engine 301, and this internal-combustion engine acts on a live axle 302.Live axle 302 further is connected on the motor 304 via a cross box 303, and this motor is set to a side starter generator.A convertible clutch 305 is arranged between internal-combustion engine 301 and the cross box 303.Especially when machine dallies, click in the cross box 303, this results from compression and the combustion vibration of internal-combustion engine 301.
Figure 22 shows a plotted curve, has expressed the torque M on time t among the figure.The driving torque M of internal-combustion engine 301 B, clutch capacity M KAverage torque M with motor 304 EAll in figure, showed.The click of speed changer is from compression and the combustion vibration of internal-combustion engine 301.Can reduce by operated clutch 305 by this way the click of speed changer: the torque M of internal-combustion engine 301 BTorque peak be truncated, shown in dotted line.As clutch capacity M KBe set to the average square M slightly higher than motor EHave superiority especially.Clutch torque M KCan be than the torque M of internal-combustion engine BLittle.
