Description
The present invention relates to be used for pack into the electric energy in electrochemical storage source of hybrid vehicle of optimum management---more properly be the equipment and the method for the charge level in such source.
Within the scope of the invention, " electrochemical storage source " refers to battery, particularly lithium ion (Li-ion), ni-mh (NiMH), nickel zinc (Ni-Zn) battery of any kind etc., and with the device of the known type of title " ultra-capacitor ".Hereinafter, all there are not restriction, term " battery " will be used for simplifying description no matter what scope of the present invention is.
The present invention for example more particularly be applicable to English title " the full mixing " known traditional, with the mixed drive chain car of the known rechargeable mixed type of English title " plug-in mixing " etc.
In the scope that should use, well-known, one of practical challenge that relates to the battery of realizing the electrochemical storage technology is battery whole life-span that can make vehicle-maintain usually between 10 and 15 years.
The aging of two kinds of main types taken into account once more:
-aging owing to what use; And
-so-called natural aging is even because battery is also aging when not using.
Wearing out of battery in the forfeiture gradually that shows its performance aspect institute's electric energy stored and the available output.Therefore battery should leave surplus when the life-span begins, so that it always can be up to specification aspect energy and power when end-of-life.Yet battery is an expensive component, and it should the most reasonably be sized according to the Specification of vehicle, and minimizing its cost, this is the first planning criterion of successfully putting on market with hybrid vehicle and elec. vehicle.
Charge condition and temperature that two principal parameters that influence its life-span are batteries.For example, the storing temperature of battery or utilization are low more, and its life-span is just long more.Equally, the charge condition of battery or utilization are low more, and its life-span is just long more.
Natural aging is a parameter of far can not ignore.In fact, general, the time of vehicle 95% is in the so-called " STOP " pattern (rest on stop in the garage, lastingly vehicle etc.).Therefore, some technology is compared more from the aging restriction of its use with quilt in addition and is limited by natural aging.
On the other hand, can consider that the aging natural aging that is similar in so-called " circulation " pattern is because the effect of electric current is by the either large or small temperature build-up performance as the function of this current's intensity.
Therefore, in order to improve the life-span of mixed drive chain vehicle:
1. should be for example through coming to obtain as possible lowest possible storage or serviceability temperature by means of actv. ventilation or a/c system; And
2. the charge condition that should reduce battery as far as possible is to reach and to use compatible minimum level.
Therefore the life-span in electrochemical storage source depends on the temperature that its charge condition and it are stored and use.In order to confirm this notion, the following general nature life-span is provided usually at commercially available lithium cell according to charge condition:
-be 18 years for the storage when 50% charge condition and 25 ° of temperature, and
-be 2.6 years for the storage when 100% charge condition and 25 ° of temperature.
When at the temperature place average charge state that equates when 50% changes to 100%, see the very large reduction of life-span of this battery.Equally,, then see sizable reduction in this life-span if average running temperature changes to 60 ° from 25 °, and if these two adverse factors combinations (high temperature and high charge condition), it is also bigger that this reduces nature.
In order to attempt to improve the battery of packing in the hybrid vehicle along with the performance in past time, when vehicle in car-parking model, it will be possible when the stop that prolongs, making the discharge of storage source at least.Can for example give for example ventilation and air-conditioning installation power supply of power consumpting device.
As an example, in the prior art, in patent application FR 2 891 774 A1 (Reynolds), such equipment and method have been described.The equipment of the type lithium ion battery of the management vehicle that is used for packing into has been instructed in this patent application, and this vehicle comprises the charge detector of this battery and the partial discharge device of battery, so that its charge condition drops to predetermined threshold value.And, in one embodiment, obtain partial discharge through the live part of battery being transferred to second lead-acid battery.
Yet said method only is adapted to the optimization needs felt by halves.In fact, very clear, utilize the essentiality of second battery to have defective: volume, weight, excess charges etc.On the other hand; In another distortion of being instructed; Always at the parking period that prolongs, partial discharge can be uniquely through obtaining for drafting apparatus (motor-driven ventilating set) power supply, and this drafting apparatus allows the cooling of battery certainly; But the loss with electric energy comes to an end, because the partial discharge of battery only in the end is utilized.
The object of the invention is to alleviate the defective of the equipment of prior art, and some defective in these defectives just is alerted.
The purpose that the present invention confirms is to be used for optimum management pack into the equipment and the method for the battery of the hybrid vehicle electric energy that---more generally to be the storage source of supplying with the electrochemical energy of mixed drive chain---provided.When vehicle stopped (being called " car-parking model " hereinafter) in the time of an elongated segment, the peculiar layout of the present invention allowed said storage source to be under the predetermined charge condition threshold value, wore out so that reduce it.
For this reason, first key character according to the method for the invention at the stroke end, that is to say, before arriving car-parking model, increases the contribution of electrical motor, so that battery is under the threshold value in this pattern.Be used to realize that according to the method for the invention equipment comprises the massaging device of vehicle; More properly be the modern notion vehicle automatic data processing equipment (ADPE) of the for example digit count type of outfit usually, it is indicated to the only remaining preset distance x in final destination that vehicle will be in car-parking model to vehicle.
More accurately, the computing machine of the mixed drive chain of management vehicle utilizes two kinds of control algorithms or rule:
-outside the route of the final destination that will be placed in car-parking model near vehicle, computer-implemented so-called first " normally " algorithm of the mixed drive chain of management vehicle, it has nothing different with the algorithm of prior art at the beginning,
In case the computing machine of the mixed drive chain of-management vehicle is notified vehicle to be positioned at the preset distance place that will be placed in the place of car-parking model from vehicle; Perhaps exist vehicle to be placed in sizable possibility of car-parking model in this place at least; It just utilizes so-called second special algorithm at the stroke end---adapt to the algorithm of the respective contribution of electrical motor and Thermal Motor, so that return under the charge condition threshold value of being scheduled to during placing car-parking model at the charge condition of stroke end battery.
In preferred implementation of the present invention, the massaging device of vehicle comprises in-vehicle navigation apparatus, and it comprises the geo-positioning system through so-called " GPS " (global positioning system) type satellite.Other system is available naturally.For example, in future, when capable of using, Europe " Galileo " system can be used to replace or replace " GPS " system.
In equally preferred embodiment, the massaging device of vehicle is relevant with learning device, the stroke that this learning device is realized along with vehicle with the data storage relevant with the place of the common parking of vehicle or position in memory storage.
The present invention supposes the equipment that has the charge condition of measuring battery naturally, but that such equipment is technical personnel is known, therefore need not describe it in more detail.
According to the configuration of the system's (navigationsystem, GPS, computing machine or management program type etc.) on the vehicle Already in, apparatus and method according to the invention is according to several kinds of actual embodiments---especially according to four kinds of following main modes---possibly worsened:
-for the vehicle that has the integrated with guidance system,, utilize the information of this equipment in the time of can being provided in the situation of destination usually for the ignorant stroke of user.
-for the vehicle that has the integrated with guidance system; But the situation of its stroke is not provided; Because known by the user, GPS position measuring system capable of using, its near in computing machine, enumerate for example present the destination of frequent car-parking model the time relevant with this navigationsystem.So must in equipment of the present invention, prepare learning system, its store car is placed the geographic position in the place of car-parking model continually.This information can be by the temporal information completion, so that distinguish parking site of different nature, and for example parking site during on weekdays and the parking site during weekend.
-for the vehicle that does not have navigationsystem, the GPS position measuring system of any external device of the information network that is connected to vehicle capable of using is for example always for example connecting the system that exists on some portable phone of networking through so-called " bluetooth " type.When near in computing machine, enumerate for example present the destination of frequent car-parking model the time, this information is passed to the control computer of mixed drive chain.As before, must in equipment of the present invention, prepare learning system equally, its store car is placed the geographic position in the place of car-parking model continually.This information equally can be by the temporal information completion, so that parking site during distinguishing on weekdays and the parking site during weekend.
-last, for both not having navigationsystem also not have integrated GPS or be connected to the vehicle of the possibility of external system, learning system can be learnt based on mileage.In this case; Must consider working day so as to obtain so-called " work " route at least and " weekend " route between difference, and corresponding moment on daytime, purpose is the place that places car-parking model according to time management; That is to say, respectively " work place " or " place, residence ".

Hereinafter, scope is any all not restriction, and we are in the scope of advantageous applications of the present invention hereinafter,, that is to say type lithium ion of in hybrid vehicle, loading onto or the similarly optimum management of the electric energy of battery only if mention on the contrary.
Fig. 1 schematically shows the example according to the optimum management equipment 1 of such battery BAT of preferred implementation of the present invention.
Should understand fully, constitute on the Already in a lot of whole or in part modern notion vehicles of main device, equipment and circuit according to equipment 1 of the present invention.For major part,, or, only need little change for fraction without any need for change.As an example, program recorded should only be suitable for adapting to the characteristic of method of the present invention in some computing machine, will detail like hereinafter.These characteristics are expression extra advantage of the present invention in addition.
Also show Thermal Motor MTH and the electrical motor MTE of hybrid vehicle VH in the figure; According to one of essential characteristic of the present invention, the corresponding contribution of Thermal Motor MTH and electrical motor MTE is under the control according to energy-optimised managerial tools 1 of the present invention through two control rules by means of different so-called " normally " and " specific ".
The last data of connection different module and the mechanical connection of power-type electrical connection and driving engine MTH and MTE and vehicle VH of in Fig. 1, having illustrated.The operation of these mechanical connections and driving engine MTH and MTE itself has no difference with prior art.Therefore it is unhelpful describing it in more detail.
The contribution of heating power and electrical motor MTH and MTE when in a manner known way, the monitor 10 difference management vehicle VH of mixed drive chain drive.For this reason, the monitor of mixed drive chain 10 is controlled the control unit 12 of Thermal Motor on the one hand, and the control unit 14 at control motor on the other hand.The latter comes control motor MTE through the current converter 13 by battery BAT power supply.
In the described example of Fig. 1, navigationsystem 16 comprises proper navigationsystem 160, and it has computing machine and display equipment (not shown) and GPS type position measurement apparatus 161 usually.The module that is called BSI (intelligent servo case) 15 of one of navigationsystem 16 computing machine through constituting vehicle VH is come to one of the monitor 10 transmission following messages of mixed drive chain or another according to engineering selection predetermined and that will clearly express hereinafter:
The geographic position of-vehicle the VH that calculates by GPS measuring equipment 161;
-or placing the distance that remains to be covered before the car-parking model by what navigationsystem 160 was calculated;
-or the change definite value of the control rule of the mixed drive chain that calculates by navigationsystem 160.
In all cases, place the geographic coordinates in the place of car-parking model should be stored in memory device continually.
This is stored in the memory storage of the monitor 10 that is equipped with the mixed drive chain and realizes, this is itself not calculate under the situation of change definite value of control rule of mixed drive chain in navigationsystem 16.Under opposite situation, this is stored in the memory storage of the computing machine that is equipped with navigationsystem 161 and realizes.
To arrive navigationsystem 16 that notified or during according to preset distance in the destination that memory device is read of the geographic coordinates of the position that places car-parking model continually as vehicle VH; The monitor 10 of mixed drive chain is used so-called " specific " control rules, and it controls the contribution that rule is compared obvious increase electrical motor MTE with so-called " normally " that be applied to all the other strokes that vehicle VH accomplished.This switches constant value calculation is realized by the computing machine 160 of navigationsystem 16 or the monitor 10 of mixed drive chain according to above-mentioned selection technology.Should " specific " control the charge condition that rule allows to reduce battery BAT; It is called " SOC " (charge condition) hereinafter; SOC is by so-called BMS (battery measurement system; According to normally used English title) 11 calculating of charge condition measurement module, so that the latter is having under the threshold value that is in predetermined charge condition SOC on the position of identifying of car-parking model.The signal of measuring charge condition SOC is transferred to the monitor 10 of mixed drive chain through the connection of data.
The monitor 10 of mixed drive chain is by means of the consumption and the CO that optimize hydrocarbon fuel
2The contribution that comes the Thermal Motor MTH and the electrical motor MTE of managed-mixed chain of the energy management algorithm of discharging, the life-span that keeps the BAT battery simultaneously.In a manner known way, the chaufeur (not shown) of vehicle VH puts teeth in mechanical couplings definite value C by means of pedal.According to aforementioned algorithm, two couplings of its definition definite value:
The coupling definite value C of-Thermal Motor MTH
1, and
The coupling definite value C of-electrical motor MTE
2,
C
1And C
2With equal C at any time.
The temperature of the charge condition that depends in part on battery BAT of the machinery of electrical motor MTE contribution and this battery when vehicle VH drives.For example, during the level of the charge condition SOC battery BAT is in the lower limit of permission near, the contribution of Thermal Motor MTH keeps preponderating.The development of control rule, positive management algorithm is called normal and called after SOC so that the charge condition SOC of battery BAT keeps approaching us
MnormaleThe definite value of predetermined charge state.
As indicated; Compare with " specific control rule "; We are called " normally controlling rule " with this control rule; Specific control rule is compared the contribution that increases electrical motor MTE with so-called " normally " control rule, so that reduce charge condition SOC, makes battery BAT reach the value that is lower than predetermined threshold; Rather than place the car-parking model of vehicle VH, this predetermined threshold to be called parking threshold value " SeuiilPark " (for the storage of the overall safety of battery BAT and the dead ship condition that prolongs) hereinafter.
With " normally " control rule contrast of being adopted by threshold value SeuiilPark, " specific " control rule is therefore relevant with the restriction that replenishes.In " specific " control rule, be called SOC
MspecifiqueThe level of definite value of charge condition of battery BAT be SOC for example
Mspecifique＜SOC

Now will be through more specifically coming to describe in more detail to relate to first practical embodiments of vehicle with reference to figure 2 and 3, this vehicle comprises the optimum management equipment according to the charge condition in electrochemical storage of the present invention source that is equipped with integrated notice navigationsystem.
The monitor 10 (Fig. 1) of mixed drive chain receives the information of expression up to the distance X that remains to be covered at a distance of the geographic coordinates position D of predetermined value d from final geographic coordinates position F (placing the car-parking model of expectation).This distance X is calculated by navigationsystem 16.Until position D, the monitor 10 of mixed drive chain is used so-called " normally " control rule.Estimate by GPS measuring equipment 161 apart from d.
When vehicle VH was on the D of geographic coordinates position, the monitor 10 of mixed drive chain made counting machine increase progressively (in Fig. 1, not schematically showing), and it calculates from the position D distance Y that F covers to the final destination at any time.On the other hand, the D from this geographic coordinates position, the monitor 10 of mixed drive chain begin to use so-called " specific " control rule according to one of essential characteristic of the present invention.
If do not locate yet the chaufeur decision is not parked in the geographic coordinates position F (it is considered to represent the final destination) that navigationsystem 16 is notified or the monitor 10 of mixed drive chain is discerned; And vehicle VH is away from this position F; When this reaches predetermined new value a at interval; That is, with respect to the value (d+a) of geographic coordinates position D, the monitor 10 of mixed drive chain is used normal control rule again.
When vehicle VH arrive from the new final destination F ' of parking geographic coordinates apart from d be called the geographic coordinates position with reference to D ' time, the cycle of just having described repeats.It should be noted that if vehicle VH turns back, this final destination F ' possibly obscure with the fwd final destination.
In the description in front, suppose that optimum management equipment 1 according to the battery BAT of preferred embodiment is equipped with the navigationsystem 16 (be integrated into the system of equipment 1 or have the networking mobile units that GPS inserts) of traditional type.Under opposite situation, available permission replaces integral body " navigationsystem 160-GPS 160 " according to the computing machine (not shown) that time of departure, the kilometer distance of since last " parking site ", having covered and expression " cut-off time table, parking period or length of the halt and until the distance of next parking site " and the ternary data computation that is recorded in the accumulation in the storage list separate vehicle VH and destination (parking site).To the necessary device of aforementioned calculating is available (possibly seek help from car-mounted computer, vehicle electronics clock etc.) in the notion vehicle in modern times usually.
Fig. 2 illustrates the charge condition SCO (ordinate) of battery BAT and the diagram of curves of the typical evolution of the relation curve of the distance (abscissa) (being respectively variable X and Y) that separates the geographic coordinates F of vehicle VH and final destination.
Do not put the position D of F as long as vehicle has arrival to off normal, normally control rule and just be employed, and the definite value of charge condition equals SOC apart from d

Shown in preceding, if vehicle is not parked in the geographic coordinates F place of the final destination of expectation, be lower than value (d+a) as long as separate the distance Y of this F and vehicle VH, specific control rule just continues to be employed, and the definite value of charge condition keeps equaling SOC

Fig. 3 is illustrated in the stage of carrying out in the practical embodiments of just having described or the logical diagram 2 of step:
The module 20 that is called " normal strategy " is the modules that are exclusively used in the application of so-called " normally " control rule.This module 20 by priori be integrated in the monitor 10 of mixed drive chain.
Under opposite situation (branch " is "), distance Y and value (d+a) that second comparison module 22 has relatively been covered since the D of position.If distance Y, then starts " normal strategy " module 20 less than (d+a) (branch " denys ") and uses normal control rule.
Under opposite situation (branch " is "), the module 23 that is called " specific policy " is activated to be used to use specific control rule.
The process of just having described constantly repeats (turning back to module 20 from the output of module 23).
Now will be through more specifically coming to describe in more detail to relate to second practical embodiments of vehicle with reference to figure 4; This vehicle comprises the optimum management equipment according to the charge condition in electrochemical storage of the present invention source; It is equipped with non-notice integrated with guidance system or does not also have the integrated with guidance system, but is equipped with the information network that is connected to vehicle VH and sends the suitable external system of GPS position (geo-location) information of this vehicle.
When vehicle VH be positioned at the external GPS measuring equipment estimated from final purpose destination location F distance during for the position D of the front definition of d; The monitor 10 of mixed drive chain increases progressively counting machine, and counting machine calculates the distance Y that from position D advances to the geographic coordinates F of final destination.As before, the D from the position, the monitor 10 of mixed drive chain is used so-called specific control rule.
Equally; And, do not locate if the chaufeur decision is not parked in geographic coordinates position F (it is considered to represent the final destination), and vehicle VH is away from this position F to be quite analogous to the mode of the mode of in first embodiment, describing; When this reaches new predetermined value a at interval; That is, with respect to the value (d+a) of geographic coordinates position D, the monitor 10 of mixed drive chain is used normal control rule again.
Fig. 4 is a charge condition (ordinate) that battery BAT is shown and the diagram of curves of the typical evolution of the relation curve of the distance (abscissa) of the geographic coordinates F that separates vehicle VH and final destination.
The diagram of curves of Fig. 4 is similar to the diagram of curves of Fig. 2 very much, is to send the characteristics of system of GPS position of vehicle VH except be not equipped with notice navigationsystem or present unique equipment owing to this equipment.Particularly, the curve S OC of the instant variation of the charge condition of expression battery BAT
iDevelopment at first sight the curve with shown in Figure 2 is identical, can be used for comparable vehicle ' condition naturally.Particularly, curve when normal control rule is employed from value SOC
MnormaleA part to another part fluctuation, and when specific control rule is employed, be in value SOC fast
MspecifiqueUnder (from position D).Therefore redescribe Fig. 4 no longer in more detail.
To explain the location management process that is called GPS in more detail now, that is to say, the geo-location of the vehicle through obtaining the geographic coordinates of vehicle on map.
There are three kinds of possible main sources that are used to obtain this GPS position:
-the vehicle mounted GPS guidance system relevant with the sensor of proprioception type (automobile runs mileage mensuration, the angle of bearing circle, the speed of a motor vehicle ...): such system is particularly suitable for providing point-device location information;
-(the instrument type flows) is vehicle-mounted or turn to the GPS navigation system: such system provides the enough location informations with good particularity of the contemplated application of the present invention; Perhaps
-have a networking mobile units that GSM inserts (for example, portable phone or have any similar instrument of information network of the be connected to vehicle VH of GPS function): that such system provides relative inaccuracy (radius of general about 2km) but same to the enough location informations of the contemplated application of the present invention.
According to source available on vehicle, the situation below considering:
If-having the geographic coordinates position F (Fig. 2 and 4) in final place uniquely, the initiation of so-called specific control rule is in the Distance Remaining d place startup of leaving final place F of being calculated through considering straight-line distance uniquely at D place, geographic coordinates position.
If-do not have the geographic coordinates position F and the navigation data in final place, at D place, geographic coordinates position the initiation of so-called specific control rule through consider that the most probable route that vehicle VH chooses the road through (by learning program or the estimated route of data that provides from the navigationsystem in guided mode) calculated between position D and final position F from the Distance Remaining d of final place F startup.
See from function view, can distinguish three kinds of main devices that on vehicle VH, exist:
-have hereinafter device (Fig. 1: navigationsystem 16) by " navigation " function of general terms " navigation " expression.Within the scope of the invention, be considered on the meaning of term " navigation " Ying Zaida, that is, calculating separates the system of vehicle and final destination, and is not only the navigationsystem according to traditional definition, that is to say location and route calculation system.Therefore, term " navigation " can be particularly useful for proposing the system from the distance of destination according to date, cut-off time table and milimeter number within the scope of the invention.
-guarantee the device of the guiding of combination drive function, it is by term " monitor of mixed drive chain " (Fig. 1: 10) expression; And
-guarantee vehicle general utility functions coordination and by term " BSI " (Fig. 1: the 15) device of exchange of management of expression.
About the exchange of information, there are several kinds of possibilities in the computing machine according to function " calculating Distance Remaining d " is transferred to:
1. " navigation " can be through " BSI " and " monitor of mixed drive chain " exchange message.
2. the exchange between " BSI " and monitor should be reduced to minimum to avoid blocking the message of vehicle.
3. the exchange of information can be accomplished according to three kinds of patterns:
-by the transmission (incident) of information requested;
-continuous information is sent (periodically); And
-continuous transmission (mixing) after request.
4. the character of tradable information depends on the device of realizing function " calculating Distance Remaining X " and " comparing with threshold value d ".
4.1 if this function is transferred to " navigation ": Boolean type computing regulation " normally " control rule is to the conversion (" Distance Remaining X＜d km ": result " very " or " vacation ") of " specific " control rule.
4.2 if this function is transferred to " monitor of mixed drive chain ", can present two kinds of situation:
4.21 the so-called solution that minimizes basically of the residue straight-line distance of considering uniquely to be calculated: this calculatings is realized by " monitor of mixed drive chain " from the present position and the final geographic coordinates position F to be arrived of vehicle; And
4.22 consider the so-called transfer solution of the most probable route that vehicle VH is chosen the road through to final geographic coordinates position F to be arrived: the distance of covering before the F in the in-position is transmitted to allow " normally " control rule to control the conversion (through comparing the threshold value of Distance Remaining X and d km) of rule to " specific ".
Can consider two kinds of main hypothesis:
First hypothesis: function " Distance Remaining X " and " comparing with threshold value d " are transferred to " navigation ".
There are several interests in this solution:
-by means of the updating device of " navigation " (for example; By means of conventional information support own; Support for this conventional information; Refresh routine is by records such as so-called USB type key, CD or DVD) allow possibly the upgrading of logic device of these operations (for example, the new parametrization of the threshold value of Distance Remaining d);
-available computing power is more important: can obtain approximately preferably, the more favourable and scalability transfiguration of cost performance is prone to;
If-navigation exists, then function is unique available: therefore directly be incorporated in " navigation " this function more appropriate; And
-with the exchange of " monitor of mixed drive chain ": except host-host protocol, 1 bit is just enough.
Alternatively, can imagine in " navigation " or " monitor of combination chain " started this function via the punctual request of " BSI ".
Second hypothesis: function " Distance Remaining X " and/or " comparing with threshold value d " are transferred to " monitor of combination chain ".
This solution has the function single-piece benefit of reorganization mixed drive chain; But have several shortcomings, especially the essentiality of the computing power of the prior loading of the message between " monitor of combination chain " and " navigation " and increase " monitor of combination chain ".Therefore in possible measure, preferably seek help from first solution, because second solution causes higher cost.
Alternatively, can imagine and have only function " with threshold value d relatively " transfer to " monitor of combination chain ".
Now will be through more specifically explaining the learning process that in preferred implementation of the present invention, realizes with reference to diagram of circuit shown in Figure 5.
First computing machine 30 determines whether that driving engine is activated." driving engine " should refer to the mixed drive chain.If result relatively is (branch " denys ") born, the geographic coordinates of the current time (time stamp data) of the vehicle-mounted clock HC that is then received and last known position of vehicle VH is stored in first memory storage 31.If result relatively is positive (branch " is "), then second comparator 33 confirms whether the GPS position of vehicle is available.If result relatively is positive (branch " is "), then new GPS position is recorded in second memory storage 34, replaces or replace the position of record in the past.If result relatively is (branch " denys ") born, then compares than returning of device 30 and be used for new comparison.Memory storage 34 is received in the geographic coordinates that the gps system (the for example system 161 of Fig. 1) that is noted as GPS on Fig. 5 is sent.Memory storage is connected to first data bank 35 of record first known location.This data bank itself is connected to first memory storage 31.The data that are recorded in the memory storage 31 are transferred to the position of registration of vehicle VH and second data bank of time on the one hand, are transferred to the 3rd comparator 37 that determines whether that driving engine is activated on the other hand.If result relatively is positive (branch " is "), then computer device 36 is activated.Computer device 36 calculates the parking period of the vehicle of the current time that data and clock HC from be recorded in data bank 35 provided.Result calculated is transferred to module 38, and it is parking period and existing list corresponding to the vehicle location of these parkings relatively, upgrades these tabulations and in table, writes the result of these operations---especially in the 3rd data bank 39 of record parking period---.Under opposite situation, if the result of the comparison that is realized by comparator 37 is (branch " denys ") born, then its input item is carried out returning of repetition, and new relatively being performed.
Should understand well,---especially memory storage, data bank and computer device---expression can be binned in unique electronic building brick with being separated whole or in part though the disparate modules of Fig. 5.This can relate to " tangible " circuit, or at least to a part (addressing of comparator function, computer device, memory storage etc.), relates to the logging program digital computer.
The example of structure of data bank of geographic coordinates that writes down parking period and the position of corresponding vehicle is illustrated by " Table I " that be placed on this specification sheets end.In order to confirm these notions, shown in this " Table I ", be noted as " P
1-T
1", " P
2-T
2" and " P
i-T
i" three couple " parking period-position ", i is an Any Digit.
There are two kinds of possibilities that are used to preserve the time length relevant with the final position (car-parking model) of given vehicle.As the position P that places car-parking model
ZAnd time T
zWhen being obtained by equipment of the present invention, " Table I " is read:
If-position P
ZThere is (for example, P
Z=P
i): the increase time is (at T
iBecome T
i'=T
i+ T
zSituation under), or preserve maximum time (at T
iBecome T
i'=max [T
i+ T
z] situation under), or realize T
iAnd T
zBetween aviation value and preserve this aviation value (at T
iBecome T
i'=moyenne [T
i+ T
z] situation under), this is according to the strategy that is adopted; Or
If-position P
ZNot known (it is not recorded in " Table I "), then with new row " P
Z-P
i" be added in " Table I ".
Allow identification to place the place P of car-parking model
ZProcessing can realize according to the strategy that is adopted according to several method:
1. can be according to the parking period of vehicle VH to position P
ZClassification; Or
2. can select the place that possibly place car-parking model of vehicle VH as follows, for example:
-in " Table I " by n the longest place of stoppage of vehicle time enumerated, n is the numeral of being scheduled to; Or
-stoppage of vehicle is more than the place of m minute or any unit At All Other Times, and m is the value of being scheduled to equally.
For given and be recorded in the application in the memory storage (read-only memory (ROM) of for example so-called ROM type); Once for all property ground set point value m and n---and more generally be our qualified predetermined all parameters of using by equipment according to the present invention; Or be variable on the contrary, for example in addition the management program of the navigationsystem of utilizing by the user of vehicle upgrade (keyboard etc.) simultaneously.
With with the similar method of the method for expecting about equipment shown in Figure 11; That is to say; Optimum management equipment according to the battery BAT of preferred embodiment; When equipment 1 was not equipped with traditional navigationsystem 16 (be integrated into the system of equipment 1 or have the networking mobile units that GPS inserts), " Table I " can not realize.In this case, must seek help from specific memory table (not shown), it is used to make the cut-off time table corresponding with the distance that separates vehicle VH and next parking site with parking period.Therefore this table should store the ternary data of the type of " cut-off time table-parking period-next stopping distance ".Employed unit can be hour and kilometer.
Now will be through more specifically describing the distortion of study of the location in the place that is placed car-parking model continually with reference to figure 6 and 7.
To be similar to the method for Fig. 2, Fig. 6 is the instant charge condition SOC that battery BAT is shown
i(ordinate SOC) and separate the diagram of curves of typical evolution of relation curve of the distance (X or Y, abscissa) of the geographic coordinates F of vehicle VH and final destination.Instant charge condition always is included in two extreme values---and be respectively maximum SOC
MaxWith minimum SOC
Min---between.
In this distortion of according to the method for the invention realization, define specific SOCSOC
MspecifiqueEqual to hope the predetermined value SOC that in car-parking model, obtains
Park, and the second specific SOC value equals (SOC
Park+ z), for example:
SOC
mspecifique＝SOC
park＜(SOC
park+z)＜SOC
mnormale
At last, define the 3rd specific SOC value and equal (SOC
Park-y), for example:
SOC
mspecifique＝SOC
park＞(SOC
park-y)＜SOC
min
As shown in Figure 6; When vehicle VH is positioned at D place, geographic coordinates position---(d is estimated by the GPS measuring system apart from d from the position F of final destination; Fig. 1 for example: in the time of 161), the monitor of mixed drive chain increases progressively counting machine, and counting machine calculates from the position D distance Y that F ran to the final destination.On the other hand, at D place, this position, the monitor of mixed drive chain is in sight to be provided at the selection between " normally " control rule and " specific " control rule.
If the D from the position, the charge condition of battery is being higher than aforementioned value SOC
ParkThe level of+z, then the monitor of mixed drive chain is used " specific " control rule.Under opposite situation, monitor is used " normally " control rule.
If yet electrical motor is through using the instant charge condition SOC that " specific " control rule makes battery BAT
iDrop to (SOC
Park-y) under, " normally " control rule is employed again, that is to say, (the position D ' that locates apart from d ' on Fig. 6, opposite with the distortion of first embodiment: Fig. 2) before, this has the value SOC that makes instant charge condition at the position F that reaches home
iAgain the effect that increases.
If yet as in the situation of the distortion of first embodiment; Vehicle VH is not parked in F place, position; That is to say; Locate in the distance (d+a) of putting D of offing normal, the monitor of mixed drive chain is used the control rule of " normally " combination chain again, if this effect is not as being initiated (Fig. 6: D ' locates in the position) shown in preceding.
Fig. 7 is the logical diagram 4 of the logical diagram that is similar to Fig. 32 of stage and step that the method for second embodiment that has just described is shown:
The module 40 that is called " normal strategy " is the modules that are exclusively used in the application of so-called " normally " control rule.
Under opposite situation (branch " is "), second comparison module 42 confirms whether distance Y are lower than (d+a), and SOC whether
i＞(SOC
Park-y).If these results relatively are (branch " deny ") of bearing, then " normal strategy " module 40 is activated and normally controls rule again and is employed.
Under opposite situation (branch " is "), the module 43 that is called " specific policy " is activated to use specific control rule.
The process of just having described constantly repeats (output in module 43 turns back to module 40).
That has just described places the place of car-parking model and allows progressive study at the time length that stops of the vehicle in these places through storage according to various possible distortion according to the method for the invention.Thanks to this learning process and---the so-called normal and so-called specific---strategies of control rule of seeking help from two that realize the mixed drive chain, the life-span that---more properly when vehicle places so-called car-parking model---obviously increases battery through optimizing its charge condition becomes maybe (this be corresponding to the stop in the prolongation of the duration vehicle of the rule that meets the front establishment).
In order to confirm this notion, in being placed on " Table II " at this specification sheets end, reported as life-span of the model of common commercially available lithium ion battery on market general example with respect to temperature of storage (with ℃) and charge condition (with the SOC of %).
Can see, if SOC increases on the one hand, and if on the other hand in given SOC place temperature increase, the life-span of this battery reduces consumingly.In addition, practice shows that in fact this life-span keeps constant for the SOC that is lower than 50%.
Within the scope of the invention, we are more particularly interested in the optimum management of the charge condition of battery.In addition, always in order to confirm these notions, with the specific examples of consideration at 25 ℃ battery temperature, should be understood that the variation about the life-span of battery, the result who is obtained will be similar for other battery temperature.
Reach a conclusion from " Table II ": be from 17.7 natural life-span in the time of 25 ℃.Definition is the parameter of characteristic with the loss of the energy capacity of battery, is referred to as " the damage coefficient of battery " hereinafter.Temperature for SOC=50% and 25 ℃ defines this coefficient and at random equals 1.
" Table III " that is placed on the end of this specification sheets is illustrated in when equaling 25 ℃ steady temperature the variation as the damage of the damage coefficient of the battery of the function of SOC.
Always in order to confirm notion, hereinafter consideration is equipped with the situation of the hybrid vehicle VH of lithium ion battery, the opereating specification of this lithium ion battery is following: 70%≤SOC≤30%.
Suppose that in the process in life-span of vehicle, on the scope of the charge condition of permitting, each charge condition has the identical possibility that is occupied, and does not have the operating strategy of the charge condition of battery.
In this hypothesis, the SOC of battery will be:
-time of 25% on scope [70%, 60%]
-time of 25% on scope [60%, 50%]
-time of 25% on scope [50%, 40%]
-time of 25% on scope [40%, 30%]
Suppose that under SOC=50% as indicated, the influence of charge condition is not felt, and the life-span of battery is with identical at 50% o'clock.
In addition, suppose its vehicle of user's daily use 1 hour its work place, and spend 1 hour every day equally and turned back to its residence that constitutes another the conventional place that places car-parking model to the conventional place that is considered to place car-parking model.Suppose vehicle in the work place during average 9 hours in car-parking model, and Saturday and Sunday, the neither one strategy can be implemented, because stroke is to be recorded in arbitrarily and not according among the managerial tools of the present invention.
To realize or not have to realize under the situation of operating strategy of charge condition according to the method for the invention relatively damage coefficient now, and stress when such strategy exists interests the life-span acquisition of battery owing to the battery of charge condition.
To consider that at first the specific operating strategy of neither one of the charge condition of battery expected (prior art vehicle).
The time in past is the distribution of as above expecting to the distribution of the different charge conditions of battery in the life of vehicle.So through according to coming to calculate the average coefficient that damages from it in the damage coefficient weighting of the percentum of each stage elapsed time of SOC to " Table III ".Under the situation of the operating strategy of the charge condition that does not have battery, infer battery K thus
SSAverage damage coefficient:
K
SS＝0.25*3.2+0.25*2.2+0.25*1+0.25*1＝1.85。
Therefore, in the example of being adopted, the life-span of battery has reduced 1.85 times.Therefore it is converted to life-span of equaling 9.5 years (coefficient 1 corresponding to 25 ℃ of life-spans during with SOC=50%) from the life-span that equals 17.7, and this representes tangible deterioration.
Consider to realize the operating strategy of battery charging state according to the method for the invention now.In described specific examples; This strategy is to prepare a computing machine; It confirms the end of stroke according to foregoing embodiment and the mixed drive chain is worked that the battery of vehicle is in and is lower than 50% charge condition when being in the car-parking model with convenient vehicle.
Again adopt hypothesis the same as before.Especially therefore the operating strategy of battery charging state only is applicable on weekdays during the distance that is on duty/goes home that on Saturday and Sunday, distance is to be recognized by the managerial tools according to battery charging state of the present invention arbitrarily and not.Suppose that during placing the stage of car-parking model as during travel phase, different charge condition SOC is along with the distribution of time is constant.
On weekdays, in car-parking model, SOC always is equal to or less than 50%.On weekdays, in driving mode (9 hours altogether), the distribution of the value of SOC is following:
-SOC=70% 2.5 hours
-SOC=60% 2.5 hours
-SOC＜50% 5 hour
On Saturday and Sunday, suppose that charge condition SOC is constant according to the distribution of time, car-parking model and the same in driving mode (on not by the route of layout, moving) through the supposition vehicle.Value to the SOC of these two days (48 hours altogether) is following:
-SOC=70% 12 hours
-SOC=60% 12 hours
-SOC＜50% 24 hour
For complete week, the value of SOC according to the distribution (with %) of the hours at these value places and with hour being distributed in " Table IV " that is placed on this specification sheets end of percentum be suggested.
Therefore; If use the operating strategy of the battery charging state of just having described; In particular example, calculate from the value of " Table IV ", the average damage COEFFICIENT K through this battery that the percentum weighting at each stage elapsed time of SOC is obtained as before
ASBecome:
K
AS＝0.09*3.2+0.09*2.2+0.83*1＝1.32
The ratio RE of the damage coefficient of the battery under the situation that is with or without strategy
SSASTherefore be RE
SSAS=1.85/1.32=1.4.
Compare RE
SSASAllow calculating to bring the interests in the life-span of battery by the operating strategy of the charge condition of this battery of realizing according to the method for the invention.
In said example, under the situation of this operating strategy that charge condition is arranged, the life-span is 13.4, and under the situation that is not having strategy, this life-span is 9.5 years, that is, and and 40% the increase in life-span.
In the reading in front, see easily that the present invention reaches its determined purpose well.
The present invention has lot of advantages, and it is enumerated in front and there is no need all to put forward.System especially allows to increase the life-span of battery simultaneously and the surplus that do not need too big energy capacity, so that it can meet in the predetermined Specification of the whole life period of vehicle.
The optimizing management strategy of---more generally be pack in the hybrid vehicle electrochemical storage source---obtains this characteristic through realizing battery, and does not need sizable change of the control system of mixed drive chain, and this allows to seek help from technique known own.In a preferred embodiment, in all or part of Already in modern usually concept car of the tangible circuit that it is sought help from, and realize that necessary according to the method for the invention change is reduced the change of the programming logic of car-mounted computer in essence.
Yet the present invention is not limited in embodiment and the application of describing about Fig. 1 to 7.
Equally, a lot of clear and definite examples only are presented and are used for showing essential characteristic of the present invention better, and only produce from this engineering selection in those skilled in the art's scope, and they can not limit any way that this is a scope of the present invention.
