Embodiment
Below with reference to accompanying drawing embodiments of the invention are described.In the following description, for the identical identical label of parts mark.Their title is also identical with function.Thereby do not repeat detailed description for them.
With reference to Fig. 1, the vehicle that the control gear in the embodiments of the invention has been installed is described.Motor generator set) (1) 200, PCU (Power Contro1 Unit: power control unit) 300,battery 400, MG (2) 500, mixed power ECU (Electronic Contro1 Unit: electronic control unit) 600, A/C (air conditioner) ECU 700 and A/C unit 702 this vehicle comprises:motor 100, MG (motor generator:.The control gear that embodiments of the invention relate to is for example realized by the program of being carried out by mixedpower ECU 600.
In the present embodiment,, use the hybrid vehicle thatmotor 100 has been installed to describe, but also can replace hybrid vehicle and use fuel cell car or the electric vehicle that fuel cell has been installed about vehicle.
Motor 100 makes bent axle (not diagram) rotation by combustion fuel and Air mixing gas, produces driving force.The driving force that is produced bymotor 100 is assigned on two paths by power splitting mechanism 102.A path is the path ofdriving wheel 106 by retarder 104.Another path is to drive the path that MG (1) 200 generates electricity.
In addition, connected the outlet pipe that is used to discharge the exhausting air that produces because of combustion fuel on the motor 100.In this outlet pipe, be provided with thecatalyzer 108 of purification of exhaust gas.Thiscatalyzer 108 is that hydrocarbon and carbon monoxide are oxidized to carbon dioxide and water, and the three-way catalyst of nitrogen oxides reduction.In order to make thiscatalyzer 108 performance catharsiss, need fully thiscatalyzer 108 of heating, for example after stopping for a long time, pilotedengine 100 o'clock, because the temperature ofcatalyzer 108 is low, thereby need be used to improve the warming-up of temperature.In the present embodiment, differentiate the warming-up that whether needs to carry outcatalyzer 108 with catalyst temperature TC.
For this reason, on the position of theclose catalyzer 108 of outlet pipe, be provided with catalyst-temperature pickup 602.This catalyst-temperature pickup 602 links to each other with mixedpower ECU 600, and the signal of representing catalyst temperature TC is sent to mixed power ECU 600.When catalyst temperature TC is lower than predetermined temperature, differentiate for carrying out the warming-up ofcatalyzer 108.
In addition, for the warming-up that whether needs to carry outcatalyzer 108, for example also can differentiate by measuring the launched operation of self ignition switch (not have diagram) transit time or engine water temperature or the transit time after system brings into operation afterwards.
In addition, though the hybrid vehicle in the present embodiment hasmotor 100 andcatalyzer 108, but also can replace them to constitute other structures, for example also can have fuel cell, modification device and catalyzer, the gas (especially CO) that is produced when wherein, described catalyzer purification utilization modification device extracts hydrogen.
MG (1) 200 drives by the power of themotor 100 that distributed bypower splitting mechanism 102, thereby generates electricity.The electric energy that is sent by MG (1) 200 is according to the state of the operating condition of vehicle or the residual capacity of battery 400 (SOC:State Of Charge, charged state) and by flexible Application.For example, when cruising or anxious the acceleration, the electric energy that is sent by MG (1) 200 is supplied to MG (2) 500 by PCU 300.
On the other hand, when the SOC ofbattery 400 was lower than predetermined value, thetransducer 302 of the electric energy that is sent by MG (1) 200 by PCU 300 was transformed to direct current from Ac, and adjusts voltages bytransformer 304, is stored into then in thebattery 400.
Battery 400 is the battery pack that constitute by a plurality of battery modules that a plurality of monocels are combined into one that are connected in series.But, also can replacebattery 400 and the use capacitor.
MG (2) the 500th, the three phase current electric rotating machine.The electric energy of at least one side in the electric energy that MG (2) 500 sends by the electric energy that stores in thebattery 400 with by MG (1) 200 drives.The driving force of MG (2) 500 is passed on thewheel 106 by retarder 104.Thus, MG (2) 500auxiliary engines 100 make vehicle driving, perhaps only make vehicle driving by the driving force from MG (2) 500.
When the regenerative braking of vehicle,wheel 106 drives MG (2) 500 by retarder 104, thereby MG (2) 500 moves as generator.Thus, MG (2) 500 moves as Brake Energy is converted to the regeneration brake of electric energy.The electric energy that is sent by MG (2) 500 is stored in thebattery 400 bytransducer 302 andtransformer 304.
Mixedpower ECU 600 is based on the map of storing in the SOC of the variance ratio of the operating condition of catalyst temperature TC, vehicle, accelerator open degree, accelerator open degree, gear,battery 400 and temperature, the storage and program etc. and carry out calculation process.Thus, installed device on the mixedpower ECU 600 control vehicles is so that vehicle is in the operating condition of expectation.
Mixed power ECU 600 is lower than predetermined temperature determining catalyst temperature TC, in the time of need carrying out the warming-up ofcatalyzer 108, the execution warming-up travels, that is:pilot engine 100, and the exhausting air of utilizingmotor 100 to discharge is carried out warming-up tocatalyzer 108, simultaneously make vehicle driving with the driving force from MG (2) 500, wherein said MG (2) 500 is bybattery 400 supply electric energy.
When during the travelling of hybrid vehicle, when the SOC of battery 40 reduces to X% (for example, 40%), differentiate for can't be from the state ofbattery 400 to MG (2) 500 supply electric energy.In the case, do not supply electric energy frombattery 400 to MG (2) 500, hybrid vehicle is only travelled by the driving force of motor 100.At this moment,motor 100 drives MG (1) 200, and the electric energy that is sent by MG (1) 200 is stored in thebattery 400.
Mixedpower ECU 600 links to each other with A/C_ECU 700, thus receiving and transmitting signal mutually.In addition, A/C_ECU 700 links to each other with A/C unit 702.A/C_ECU 700 is according to by car indoor temperature transmitter 706 detected car room temperatures and by the serviceability of theswitch 708 of occupant's operation, control A/C unit 702.Blow out the air of the blowing temperature of setting by A/C_ECU 700 from A/C unit 702.A/C_ECU 700 determines to drive the voltage of A/C fan 704 based on the classification of car room temperature.
In addition, A/C_ECU 700 calculates in the A/C unit rotating speed of 702 drivencompressors 800 when carrying out cooling operation.Utilize technique known to get final product owing to calculate the method for the rotating speed ofcompressor 800, therefore do not repeat its detailed description here.
The rotating speed of thecompressor 800 that is calculated sends to mixed power ECU600 from A/C_ECU 700.The A/C transducer 802 that mixedpower ECU 600 controls link to each other withbattery 400 is so that the rotating speed ofcompressor 800 reaches the rotating speed of calculating.Compressor 800 drives by the power supply that A/C transducer 802 receives from battery 400.Compressor 800 drives, compressed refrigerant, thus A/C unit 702 carries out cooling operation.In addition, also can utilize from the electric energy ofbattery 400 supplies, and A/C unit 702 heats running.
A/C unit 702 except the occupant from the situation of car in-house operation switch 708, under the situation of outside car, having operatedcommutator 900, also can turn round.In order to receive the signal that sends fromcommutator 900, on A/C_ECU 700, connected receiving machine 902.By thesecommutators 900 and receivingmachine 902, can carry out the precoditioning (プ レ Kong Tone) of before the occupant enters in the car, carrying out cooling operation or heating running.
This precoditioning is under an embargo under the situation that does not satisfy predetermined condition.When precoditioning is under an embargo, utilize thetutorial light 1000 in the combination instrument (not having diagram) to inform that to the occupant precoditioning is under an embargo.In the case, the occupant can grasp the forbidden situation of precoditioning into the car the time.
Inform that the method that precoditioning has been under an embargo is not limited thereto, and in addition also can show that on the display device of display device on the control panel or automobile navigation instrument precoditioning is under an embargo.Also can inform that precoditioning is under an embargo with sound.Also can be undertaken in addition by the lamp of lighting or extinguish on the switch that is arranged oncommutator 900 or receivingmachine 902.
The control structure of the program of being carried out by mixedpower ECU 600 in the control system of the vehicle that relates to about present embodiment describes with reference to figure 2.
In step (simply being S with step below) 100, mixedpower ECU 600 differentiates the operation request whether precoditioning is arranged based on the signal that sends from A/C_ECU 700.When the operation request of precoditioning (being "Yes"), handle changing among the S102 in S100.If there be not (being "No" in S100), this is just handled and finishes.
In S102, the SOC of mixedpower ECU 600 counting cells 400.SOC obtains according to the integral value of the charging and discharging currents value of battery 400.Computational methods about SOC can be used technique known, thereby no longer repeat here to describe in detail.
In S104, whethermixed power ECU 600 differentiates the SOC ofbattery 400 greater than Y% (for example, 50%).Here, Y% is set to such value: even the SOC ofbattery 400 reduces during carrying out that warming-up travels, in the moment that warming-up finishes, the SOC ofbattery 400 can be less than X% yet.Y% is specifically, by various operating modes such as the long-time parking of hybrid vehicle combination, slow acceleration, anxious acceleration are experimentized, and the reduction of the SOC of thebattery 400 that reduces till obtaining warming-up and finishing, and this amount is added to the value that lower limit (X%) thatbattery 400 can power goes up gained.As the SOC ofbattery 400 during greater than Y% (being "Yes"), handle changing among the S106 in S104.If not (being "No"), handle changing among the S108 in S104.
In S106, mixed power ECU 600 allows precoditioning.At this moment, mixed power ECU600 sends the signal that expression allows precoditioning to A/C_ECU 700.Thus, A/C_ECU 700 control A/C unit 702 are with operation precoditioning.
In S108, mixedpower ECU 600 forbids precoditioning.At this moment, mixed power ECU600 sends the signal that precoditioning is forbidden in expression to A/C_ECU 700.Thus, A/C_ECU 700 control A/C unit 702 are not to carry out or to stop precoditioning.
In S110, mixed power ECU 600 lights thetutorial light 1000 in the combination instrument (not having diagram), informs that to the occupant precoditioning is under an embargo.
The following describes the operation of the mixedpower ECU 600 of the control gear that present embodiment relates to based on said structure and flow chart.
When be at Vehicular system stop in the middle of, thereby whenoperation commutator 900 has been asked the operation (in S100 for "Yes") of precoditioning, the SOC of counting cell 400 (S102), and whether differentiate SOC greater than Y% (S104).
As the SOC ofbattery 400 during greater than Y% (being "Yes" in S104), allow precoditioning (S106), the signal that will expression allows sends among the A/C ECU 700.Thus, A/C unit 702 is controlled with operation precoditioning.
On the other hand, SOC has not satisfied Y% (is "No" at S104) when the operation of precoditioning is requested (being "Yes" in S100), and perhaps SOC reduces to the occasion that does not satisfy Y% (is "No" at S104) because of precoditioning, forbids precoditioning (S108).
In case precoditioning is under an embargo (S108),tutorial light 1000 is just lighted, thereby the forbidden situation of precoditioning is apprised of to the occupant (S110).Thus, the occupant can grasp the electric energy deficiency ofbattery 400, the forbidden situation of precoditioning into the car.
As mentioned above, when the SOC that does not satisfybattery 400 greater than carrying out warming-up when travelling the condition of required SOC, the mixed power ECU of the control gear that present embodiment relates to forbids the operation of precoditioning.Thus, the minimizing that can suppress SOC guarantees to carry out the warming-up required SOC that travels.Therefore, between the warming up period of catalyzer, need not driving force, thereby the driving force that motor can be produced suppresses for catalyzer is carried out the required output of warming-up for the consumption of engine generation of travelling.Consequently, the exhausting air of amount that can suppress to surpass the purifying ability of catalyzer is discharged from.
Need the catalyzer of warming-up also to comprise the catalyzer etc. of the gas that purification is discharged from modification device, described modification device is modified as hydrogen with hydrocarbon class A fuel A, and with this hydrogen supply in motor or fuel cell.
In addition, in the above-described embodiment, be SOC according to the battery operation of determining to carry out precoditioning, but except precoditioning, also can determine according to the SOC of battery to carry out the operation of supplementary equipment classes such as burglar alarm.
In addition, in the above-described embodiment, be to determine to carry out the operation of precoditioning by mixed power ECU, but in addition, also can determine to carry out the operations of precoditioning by A/C_ECU 700.
