Description

For the method managing the hybrid power compressor of air conditioner loop
Technical field
The method that the present invention relates to the hybrid power compressor of the air conditioner loop of motor vehicles for managing band electromotor.
The present invention is in the field of air conditioning of the motor vehicles equipped with the band electromotor being automatically stopped and resetting system Have found particularly advantageous application, described system is all if implementing to be known as term " stop and starting " system of function.
Background technology
In some conditions, " stop and starting " function and including automatically causing when vehicle itself has stopped electromotor Stop completely, and exist subsequently, such as, automatically reset after being construed to the driver actions of the request of resetting and start Machine.
It is the situation stopped at red light for implementing the situation typical of " stop and starting " function.When vehicle stops at lamp Time only, " stopping " pattern of " stop and starting " function causes engine automatic stop, and vehicle subsequently enters " starting " pattern, Described " starting " pattern allows electromotor automatically to reset, and it is required for the device of the initial start for motor, Such as, contact key.When lamp turns green, order system detect clutch pedal, accelerator pedal depressed by driver or Can be construed to driver's expectation reset his any other action of vehicle and after starting vehicle, " starting " pattern oneself Move and reset electromotor, especially by alternator-starter.The benefit " stop and starting " function is saved at energy It is understood with polluting minimizing (particularly urban environment) aspect.
Further, it is known that the air conditioner loop of the vehicle of band electromotor includes refrigerant fluid compressor, it is by electromotor The axle of bent axle driven by being mechanically linked to the belt wheel of the bar of compressor and belt.In other words, the air-conditioning of vehicle Loop only can the operation when electromotor drives compressor.Therefore, the vehicle under " stop and starting " function background stops rank During Duan, compressor is no longer driven by the engine and stop operation of air conditioner.Thus, during these stop phases, can Can not keep the set point temperatures within cabin, therefore this may result in Vehicular occupant and feels uncomfortable sensation.
In order to ensure the temperature kept during the stage driving compressor at engine stop in cabin, it is proposed that such as by Hybrid power compressor including two discrete compression chamber substitutes the usual compressor driven by vehicle motor, described mixed Conjunction power compressor constitute, on the one hand, so-called mechanical compressor, its bar by electromotor in the way of identical with usual compressor Driving, on the other hand, so-called electric compressor, its bar is driven by auxiliary electric motor.The bar of Liang Ge compression chamber is independent.
When the engine is running, outside the stop phase determined by " stop and starting " function, refrigerant fluid is at sky Recall to and road cycles through by the shaft-driven mechanical compressor of the bent axle of electromotor, and electric compressor is closed.On the contrary, During " stopping and starting " stop phase of function, refrigerant fluid is guided towards electric compressor, described electric compressor then by Electric motor drive.Accordingly, because electric compressor, in the persistence of the operation of air conditioner loop and cabin, being maintained at of suitable temperature is sent out Motivation is performed after having stopped.
But, it is necessary to notice, during the stop phase of air conditioner loop, especially executed by " stop and starting " function During the engine stop stage added, cabin substantially has been adjusted to comfort conditions, thus in order to keep these conditions to continue The refrigeration work consumption being restricted to persistent period of tens seconds and provided by electric notor is than the power that must be provided by electromotor significantly Low, the lowest 2 to 3 times.Therefore it can be used for having the compression chamber reducing capacity by lower powered electric motor drive Electric compressor.
But, when air conditioner loop does not operates after the driving of mechanical compressor is interrupted by electromotor, refrigerant fluid Rearranging of pressure can occur along air conditioner loop, this be prone to produce opposing moment of torsion, for electromotor to mechanical compressor Drive stop and making electric notor be used for replace moment, electric notor must resist described opposing moment of torsion.But, at these Under part, the power variable needed for overcoming this opposing moment of torsion must be more than in order to keep cabin comfortableness and foot that electric notor necessarily be formed Enough power.
Summary of the invention
Therefore, the purpose of the present invention is to propose to the mixing of the air conditioner loop of a kind of motor vehicles for managing band electromotor The method of power compressor, described hybrid power compressor can, on the one hand, is driven by described electromotor, on the other hand, Electromotor to during the driving interrupt phase of compressor by electric motor drive, this allows to prevent that and turns round relative to opposing by using The electric notor of the power that square is the lowest and the difficulty that shows, described opposing moment of torsion is because of refrigerant fluid during the stopping of air conditioner loop The change of pressure and produce.
According to the present invention, because described method rose during being included in driving interrupt phase before described driving interruption starts Dynamic described electric notor, it is achieved that this purpose.
Therefore, driving compressor and therefore before air conditioner loop stops operation at engine stop, electric notor is opened in advance Begin to operate.Therefore, electric notor need not overcome the various changes of refrigerant fluid pressure, and it stops going out afterwards at air conditioner loop completely Now in air conditioner loop.Then can use lower powered electric notor, and there is no any shortcoming.
According to the first embodiment of the present invention, wherein, described hybrid power compressor includes the first refrigerant fluid compression Chamber and second refrigerant fluid compression chamber, described first refrigerant fluid compression chamber includes to be driven by described electromotor The first dynamic constrictor, described second refrigerant fluid compression chamber includes can be by the second compression of described electric motor drive Bar, described method includes that multiple step, the plurality of step include that detecting electromotor in advance interrupts the driving of the first constrictor Stage, include from the first compression chamber refrigerant fluid switched to the second compression chamber, and be included in electromotor to the first pressure The driving of contracting bar is interrupted starting to start before electric notor.
First embodiment is carried out, especially when described driving interruption is engine stop, and more specifically, when described Engine stop is to be determined by the function (such as " stop and starting " function) that is automatically stopped and resets of vehicle motor When being automatically stopped.
According to the second embodiment of the present invention, wherein, described hybrid power compressor includes variable capacity refrigerant fluid Compression chamber, described variable capacity refrigerant fluid compression chamber includes can be by described electromotor in the higher interval of capacity Driving and by the single constrictor of described electric motor drive in the relatively low interval of capacity, described method includes multiple step, institute State multiple step and include that detect electromotor in advance drives interrupt phase, includes the capacity of compression chamber from capacity constrictor Higher interval switch to the relatively low interval of capacity, and be included in electromotor and interrupt starting to rise before galvanic electricity to the driving of constrictor Motor.
Generally, the invention provides, the solution being electromotor with the constrictor of hybrid power compressor is interrupted in described driving Except coupling, and more specifically, the releasing to couple and be automatically stopped and reset function (such as by vehicle motor of electromotor " stop and starting " function) determine, or determined by vehicle acceleration request.
In the case of there is the hybrid power compressor of two discrete compression chamber, electromotor and the first constrictor it Between perform to release and couple, and in the case of there is the hybrid power compressor of variable capacity compression chamber, in electromotor and chamber Perform between the single constrictor of room to release to couple.
It practice, electric notor started by for examining before the driving of hybrid power compressor is interrupted starting by electromotor The device of the engine stop being automatically stopped and resetting function surveying vehicle motor performs, or by being used for detecting car The device of acceleration request performs.
In the framework of " stop and starting " function, these detection devices can change terrifically, and is generally dependent on structure The strategy that person selects.Action it is contemplated that such as, when the speed of vehicle is under given threshold value, on detection brake pedal.

Detailed description of the invention
Shown in Fig. 1 is the conventional air-conditioning loop of the motor vehicles of band electromotor, including the compressor of refrigerant fluid 10, described refrigerant fluid can be organic and inorganic or meltable fluid.Supercritical carbon dioxide CO can be quoted2For unrestricted Property example, be denoted as R134A, 1234yf or GAR(" whole world alternative refrigerant (Global Alternative Refrigerant) ").In the downstream of compressor 10, pressurized refrigerant agent fluid passes through heat exchanger 11, and it is referred to as titanium dioxide " gas cooler " of carbon or " condenser " for R134A, this is due in this case, be initially the cold-producing medium of gas phase with Liquid leaves condenser.
In the example of fig. 1, exchanger 11 can be water type exchange device, or the air class directly cooled down by extraneous air Type exchanger.
Guided towards relief valve 12 after refrigerant fluid, thus refrigerant fluid enter vaporizer 13(herein, Heat exchange then occurs between the air blowed towards the cabin of vehicle and cooled cold-producing medium) the most cooled.
The refrigerant fluid being reheated when vaporizer 13 exports is returned to compressor 10 subsequently, new to perform Thermal cycle.
As the most appreciable, the compressor 10 of Fig. 1 is the hybrid power pressure with two discrete compression chamber types Contracting machine, i.e. on the one hand, including the first chamber 101 of the first constrictor 111, this first constrictor 111 can starting by vehicle The axle of the bent axle of machine (not shown) drives via belt and belt wheel 30, and described belt and belt wheel 30 are by clutch 31 machinery ground chain Receive bar 111, and, on the other hand, including the second chamber 102 of the second constrictor 112 independent of the first bar 111, institute State the second constrictor to be driven by electric notor 20.
During the normal operation of air conditioner loop, the bar 111 of the first compression chamber 101 is driven by the engine, and belt wheel 30 leads to Cross clutch 31 and be connected to bar 111.Refrigerant fluid is circulated through the first chamber 101, the capacity of this first chamber 101 subsequently (100cmw3Level) it is selected to allow hybrid power compressor 10 and guarantees the optimum comfort level within vehicle cabin, regardless of whether The degree of external temperature, sunshine and relative humidity.
However, it is possible to happens is that, in some cases, compressor of air conditioner 10 is no longer driven by the electromotor of vehicle, and Therefore, air conditioner loop stops operation and can not ensure to maintain the suitable temperature within cabin again.This is exactly especially by for sending out Situation during the engine stop stage that the system being automatically stopped and resetting of motivation determines, described system can be implemented " stop and starting " function equipped with the vehicle of " stop and starting " function.
In order to ensure air-conditioning persistence in cabin, cycling through in hybrid power compressor 10 of refrigerant fluid Valve gear and be switched to the second chamber 102 from the first chamber 101, and electric notor 20 is started subsequently, in order to drive the second pressure Contracting bar 112 also keeps air conditioner loop to run during these stop phases.
When electric notor 20 from stop subsequently electromotor adapter time, vehicle cabin generally already at comfortable temperature, Thus, being substantially limited in the situation of tens seconds about persistent period of stop phase, electric notor 20 refrigeration work consumption provided is relatively Low.As example, in a usual manner, the refrigeration work consumption of 6kW is a need for, in order to ensure at 1000W.m2Sunshine and 50 With the comfort level in the vehicle cabin being exposed to 25 to 45 DEG C of high temperature under the relative humidity of 60%.But, when vehicle has been conditioned During to comfortable temperature, refrigeration work consumption to be provided is in 1kW to 3kW, and this depends on the section of vehicle.
Accordingly, with respect to the capacity of the first chamber 101, the capacity of the second compression chamber 102 can be limited to e.g., from about 20cm3Value.
Having shown that the hybrid power compressor 10 for driving the motor vehicles equipped with " stop and starting " function Electric notor 20 and electromotor mode of operation Fig. 3 chart in, value 0 is corresponding to the stopping of motor, and value 1 is corresponding to its behaviour Make.
As seen in the figure, when because electromotor is automatically stopped and the first compression according to " stop and starting " function When bar 111 is no longer driven by the engine, electric notor 20 begins operation to drive the bar 112 of the second compression chamber 102 therefore Ensure that the comfort level in cabin during the engine stop stage.
But, it is necessary to emphasizing, under these conditions, electric notor 20 must provide enough moment of torsion to overcome when starting Opposing moment of torsion, described opposing moment of torsion is by the refrigerant fluid pressure occurred in the engine stop moment in air conditioner loop again Arrange and cause.The moment of torsion to be provided by electric notor 20 then becomes very large and it needs to than ensuring that air-conditioning is strictly required The higher power of power.
Therefore, in order to avoid the too much overrate of electric notor 20, the present invention proposes a kind of dynamic for managing mixing The method of force compresses machine 10, described method includes that multiple step, the plurality of step include detecting electromotor in advance to the first pressure The driving interrupt phase of contracting bar 111, switches to the second compression chamber 102 including by refrigerant fluid from the first compression chamber 101, Interrupt starting to start electric notor 20 before to the driving of the first constrictor 111 with being included in electromotor.In like fashion, electric notor 20 Operation is started before air conditioner loop stops and before generation that therefore any pressure in air conditioner loop rearranges.Cause This, the power of electric notor 20 can be specified.
In order to perform, this of the starting of electric notor 20 is pre-to be first carried out, it is possible to use the dress implemented by " stop and starting " function Put, if whether be satisfied and these conditions are satisfied and just force engine stop detecting engine stop condition.
This is represented by Fig. 4, sees that the automatic stop condition of once electromotor " is stopped and starting " function in the diagram Detecting, the signal (such as being produced by car-mounted computer) started in advance of electric notor 20 is logical before the actual stopping of electromotor Cross the CAN(" Car Area Network " of vehicle) net is dispatched into the control circuit of electric notor.The automatic stop condition of electromotor depends on In the strategy that Vehicle structure person uses.Additionally, when vehicle is advanced with low speed (e.g., less than 5km/ hour), it may be considered that braking Action on pedal.
Fig. 4 illustrates another situation, and wherein, electric notor 20 can start operation, in order to guarantees to relax during air conditioner loop stops The persistence of thermophilic degree.This situation is when requiring that the optimal response to acceleration request is (by being applied to bent axle by peak torque Axle) time the situation accelerated of vehicle, realize by recovering the opposing moment of torsion that causes due to the driving of compressor.In this case, The driving of first compression chamber 101 is interrupted unrelated with the stopping of electromotor, but be used for driving the band of constrictor 111 of chamber The releasing of wheel 30 couples relevant.
In this case, once acceleration request is detected by conventional sense device and real with constrictor 111 at electromotor Border releases before coupling, and electric notor 20 starts.
Shown in Fig. 2 is the hybrid power compressor 10' including variable capacity compression chamber 100 type, described variable The bar 110 of capacity compression chamber can be driven by electric notor 20, or by the axle of the bent axle of the electromotor (not shown) of vehicle via The belt of bar 110 can be mechanically linked to by clutch 31 and belt wheel 30 drives.
Here it is necessary it is emphasized that this framework of hybrid power compressor of air conditioner is different from the compressor of Fig. 1 is, its Only implement single compression chamber and can be equal to, by electromotor or electric notor, the single bar driven rather than there are two of independent bar Discrete compression chamber.
During normal operation, the bar 110 of compression chamber 100 is driven by the engine, and belt wheel 30 is coupled by clutch 31 To bar 110.The capacity of compression chamber is then close to heap(ed) capacity (such as, such as 100cm3Magnitude) value higher interval in It is chosen.Under these conditions, hybrid power compressor 10' is able to ensure that the optimal comfort level within vehicle cabin, nothing Opinion external temperature, sunlight and relative humidity degree.
However, it is possible to happens is that, as the hybrid power compressor 10 with two chambers of Fig. 1, air-conditioning pressure Contracting machine 10' is no longer driven by the electromotor of vehicle, and therefore, air conditioner loop stops operation and no longer guarantees to maintain within cabin Suitable temperature.As seen from above, this is to be automatically stopped and resetting that function determines starts by " stop and starting " type During machine stop phase, or the situation during the vehicle acceleration request stage.
In order to ensure the persistence of air-conditioning under these situations, the driving of compressor 10' is stopped by electric notor 20 at electromotor Operation is started during stage.In other words, it may be considered that electric notor 20 drives compression chamber 100 aspect to use himself at it subsequently Substitute electromotor.It is, of course, preferable to ground, electromotor and constrictor 110 debonding.
Having already described above, the refrigeration work consumption that will be provided during operation by electric notor 20 is relatively low.
Accordingly, with respect to nominal operating conditions, the capacity of compression chamber 100 can be reduced to be in about minimum capacity (such as 20cm3) capacity relatively low interval in value.
Certainly, the higher and relatively low interval of capacity can be the most only reduced to minimum and maximum capacity.Compression chamber Room 110 then switches between both capacity with dualistic manner, and this depends on that the power drive of the bar for chamber is to start Machine or electric notor.
The situation that the power asked about electric notor is relatively low, it can be envisaged that use the electric horse with or without brush Reaching, it is by low-voltage direct-current electric current (particularly being provided by the 12V network of vehicle) power supply, and current source can be battery 40 or dress Have or be not equipped with the additional unit of reservior capacitor.
In practical ways, variable capacity compression chamber 100 can be embodied by having vaned conventional compact chamber, and it enters Entering volume (corresponding to capacity) can be at such as 20cm3Minima and such as 100cm3Maximum between by change chamber The position of middle access aperture and be conditioned.
As the hybrid power compressor 10 of Fig. 1, can be by implementing for managing hybrid power compressor 10''s Method and avoid electric notor 20 to must provide for the moment of torsion that increases because opposing moment of torsion, described opposing moment of torsion is by refrigerant fluid pressure Rearranging and causing when air conditioner loop stops, described method includes that multiple step, the plurality of step include examining in advance Survey electromotor driving interrupt phase, include the capacity of compression chamber 100 from the higher interval switching of capacity constrictor 110 To the relatively low interval of capacity be included in electromotor and interrupt starting to start electric notor 20 before to the driving of constrictor 110.
No matter the driving of compressor 10' is interrupted by electromotor is owing to what " stop and starting " function determined is automatically stopped also Due to acceleration request, electromotor to the transformation between driving and the driving of electric notor 20 of constrictor 110 by clutch 31 Couple by belt wheel 30 is released with constrictor 110 and perform.
According to Fig. 4, by starting electric notor before coupling with the actual releasing of constrictor 110 at electromotor, it is thus achieved that expectation For making electric notor 20 start pre-first carrying out of operation.
Identical for detecting those of the device of engine stop or acceleration request and the compressor 10 for Fig. 1, be all The situation of electric notor 20 is controlled by starting signal in advance.
