Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle air conditioner, and more particularly to a device that performs air conditioning correction according to the vehicle speed.
[0002]
[Prior art]
Conventionally, as a vehicle air conditioner, there is one described in JP-A-3-148323. This publication describes that the air load is corrected based on the outside air temperature and the vehicle speed, paying attention to the fact that the heat load of the air conditioner varies with the outside air temperature according to the vehicle speed. Here, in this publication, it is considered that the thermal load changes according to the vehicle speed, and when the vehicle speed increases, the outside air is blown to the outer surface of the vehicle, which affects the air conditioning state in the vehicle interior.
[0003]
[Problems to be solved by the invention]
By the way, normally, the vehicle air conditioner can be switched between an outside air mode for air conditioning outside air and an inside air mode for air conditioning inside air. And, as a result of examination by the present inventor, it was found that in the inside air mode, there is a problem that air that is not air-conditioned by the vehicle speed enters the vehicle interior, adversely affects the air-conditioning state, and air conditioning feeling is bad. .
[0004]
In other words, the vehicle has structural gaps such as manufacturing limitations, and the inside air mode is a mode that sucks in the inside air. Therefore, in the inside air mode, the pressure in the vehicle interior is lower than the pressure of the outside air, and in the inside air mode. It was found that when the vehicle was traveling at high speed, outside air entered the vehicle interior through the gap due to the traveling wind pressure.
Therefore, an object of the present invention is to correct the air conditioning according to the amount of heat of the outside air entering from the clearance of the vehicle.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention employs the following technical means. According to the first to tenth aspects of the present invention, an inside air circulation mode in which the inside air inlet (3) is fully opened and the outside air inlet (4) is fully closed, and the outside air inlet (4) is fully opened and the inside air inlet ( 3) It is provided with inside / outside air switching means (5) for switching between the outside air mode for fully closing,
The air conditioning control means (6, 17, 18, 20) determines whether the inside / outside air mode of the air sucked into the air passage (2) is the inside air circulation mode, and only when the inside air circulation mode is determined . Based on the vehicle speed, the air-conditioning state of the air blown into the passenger compartment is corrected.
[0006]
As a result, the air-conditioning control means corrects the air-conditioning state of the blown wind based on the amount of heat of the outside air that enters the vehicle interior from the gap of the vehicle that increases in accordance with the vehicle speed. Air conditioning control can be performed.
In particular, in the invention described in claim 3, when the temperature outside the passenger compartment is lower than the temperature inside the passenger compartment, the temperature control means (17, 18, 20) blows air into the passenger compartment as the vehicle speed increases. It is characterized by correcting so as to increase the temperature.
[0007]
As a result, when the temperature outside the passenger compartment is lower than the temperature inside the passenger compartment, the occupant feels uncomfortable that the outside air enters from the gap of the vehicle, and this discomfort increases as the vehicle speed increases, but as the vehicle speed increases. Since the temperature of the air blown into the passenger compartment is increased, it is possible to prevent the passenger from feeling uncomfortable and to provide the passenger with a good air conditioning feeling.
[0008]
In particular, in the invention described in claim 4, the temperature control means (17, 18, 20) increases the temperature of the blown air into the vehicle compartment as the difference between the temperature outside the vehicle compartment and the temperature inside the vehicle compartment increases. It is characterized by correcting as follows.
As a result, the greater the difference between the temperature outside the passenger compartment and the temperature inside the passenger compartment, the more discomfort that the occupant is cold due to the outside air entering the passenger compartment, but the higher the difference, the higher the temperature of the blowout air. Therefore, it is possible to prevent the passenger from feeling uncomfortable according to the air conditioning environment.
[0009]
In particular, in the invention described in claim 5, when the temperature outside the passenger compartment is higher than the temperature inside the passenger compartment, the temperature control means (17, 18, 20) blows air into the passenger compartment as the vehicle speed increases. The temperature is corrected so as to be lowered.
As a result, when the temperature outside the passenger compartment is higher than the temperature inside the passenger compartment, the outside air entering through the gaps in the vehicle gives the passenger a discomfort that it is hot, and this discomfort increases as the vehicle speed increases, but the vehicle speed increases as the vehicle speed increases. Since the temperature of the air blown into the room is lowered, it is possible to prevent the passenger from feeling uncomfortable and to give the passenger a good air conditioning feeling.
[0010]
In particular, in the invention described in claim 6, the temperature control means (17, 18, 20) lowers the temperature of the blown air into the vehicle compartment as the difference between the temperature outside the vehicle compartment and the temperature inside the vehicle compartment increases. It is characterized by correcting as follows.
As a result, the greater the difference between the temperature outside the vehicle interior and the temperature inside the vehicle interior, the more discomfort that the passengers are hot due to the outside air entering the vehicle interior, but the larger the difference, the lower the temperature of the blown air. Therefore, it is possible to prevent the passenger from feeling uncomfortable according to the air conditioning environment.
[0011]
In particular, the invention described in claim 8 is characterized in that the air volume control means corrects the air volume to be increased as the vehicle speed increases.
As a result, the air volume control means corrects the air volume to increase as the vehicle speed increases, so that the influence of outside air that is not air-conditioned by the increased air volume can be canceled and comfortable air conditioning control can be performed.
[0012]
In particular, in the invention described in claim 9, the air volume control means (6, 20) corrects the air volume to be increased as the difference between the temperature outside the passenger compartment and the temperature inside the passenger compartment increases. Yes.
As a result, the greater the difference between the temperature outside the passenger compartment and the temperature inside the passenger compartment, the more easily the passengers feel uncomfortable due to the outside air entering through the gaps in the vehicle, so the greater the difference, the greater the air volume. Comfortable air conditioning control can be performed by canceling the influence of outside air that is not air-conditioned by the increased air volume.
[0013]
Further, in the invention described in claim 10 in particular, the necessary blowing temperature calculating means (500) for calculating the necessary blowing temperature of the blowing air into the vehicle interior based on at least the temperature in the vehicle interior and the set temperature outside the vehicle interior; Based on the necessary blowing temperature calculated by the necessary blowing temperature calculating means (500), a target blowing amount determining means (600) for determining a target blowing amount of the blowing means (6) and a necessary blowing temperature calculating means (500). An air outlet mode determining means (700) for determining an air outlet mode of the air outlet (9) based on the calculated required air outlet temperature;
The air volume control means (6, 20) is characterized in that the air volume is corrected by correcting the target air volume determined by the target air volume determining means (600) based on the vehicle speed.
[0014]
Here, if the required blowout temperature is corrected according to the vehicle speed, the blowout port mode is set based on the necessary blowout temperature, which causes a problem that the blowout port mode causes hunting. However, according to the tenth aspect, since the air volume control means corrects the target air flow rate, no correction is made to the necessary blowing temperature itself. Therefore, according to claim 10, the above problem can be solved.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
Next, a first embodiment of the present invention will be described with reference to the drawings. First, the overall configuration of the present embodiment will be described with reference to FIG.
The vehicle air conditioner 1 includes an air conditioning case 2 that forms an air passage that guides air into the passenger compartment. On the air upstream side of the air conditioning case 2, there are an inside air inlet 3 for inhaling air in the vehicle interior (hereinafter referred to as “inside air”), and an outside air inlet 4 for inhaling air outside the vehicle interior (hereinafter referred to as “outside air”). The opening ratio of the suction ports 3 and 4 is adjusted by the inside / outside air switching door 5. The inside / outside air switching door 5 is driven by driving means (specifically, a servo motor) 19. Thereby, the vehicle air conditioner 1 can switch between the inside air mode and the outside air mode as the inside / outside air mode. The inside air mode is a mode in which the outside air inlet 4 is closed by the inside / outside air switching door 5 and the inside air inlet 3 is opened so that all the inside air is taken into the air conditioning case 2. On the other hand, the outside air mode is a mode in which the outside air suction port 4 is opened by the inside / outside air switching door 5 and the inside air suction port 3 is closed, so that all the outside air is taken into the air conditioning case 2.
[0016]
In the air conditioning case 2, a blower 6, a cooling unit 7, and a heating unit 8 are arranged from the air upstream side to the downstream side, and the air that has passed through the heating unit 8 is formed at the downstream end of the air conditioning case 2. In addition, the air is blown out from the air outlets 9 to various parts in the vehicle interior.
The blower 6 generates an air flow in the air conditioning case 2 and blows out air sucked from the inside air inlet 3 or the outside air inlet 4 toward the vehicle interior.
[0017]
The cooling means 7 is constituted by the refrigerant evaporator 7 of the refrigeration cycle 10. The refrigeration cycle 10 includes a refrigerant compressor 11, a refrigerant condenser 12, and a decompression unit 13 in addition to the refrigerant evaporator 7, and is a well-known one coupled by a refrigerant pipe 14. The refrigerant compressor 11 is connected to the engine 15 via an electromagnetic clutch 11a, and the power of the engine 15 is transmitted to the refrigerant compressor 11 when the electromagnetic clutch 11a is turned on.
[0018]
The heating means 8 includes a heater core 8 that uses engine cooling water (medium) as a heat source. Engine heater water heated by the engine 15 flows into the heater core 8, and the flow of the heated coolant water is adjusted by the water valve 16.
In the air conditioning case 2, a bypass passage 36 is formed for the cold air from the refrigerant evaporator 7 to bypass the heater core 8. An air mix door 17 is provided on the air upstream side of the heater core 8 to adjust the ratio of the amount of cold air from the refrigerant evaporator 7 that flows through the heater core 8 and the amount that flows through the bypass passage 36. The air mix door 17 is driven by drive means (specifically, a servo motor) 18.
[0019]
Specifically, each of the air outlets 9 includes a face air outlet for blowing air-conditioned air toward the passenger's upper body, a foot air outlet for blowing air-conditioned air toward the passenger's feet, and air-conditioning air from the vehicle window. It consists of a defroster outlet for blowing out towards the glass. These outlets are selectively opened and closed by an outlet switching means (not shown).
[0020]
In addition, the control device 20 that controls the air conditioner includes an inside air sensor 21 that detects the temperature inside the vehicle interior, an outside air sensor 22 that detects the temperature outside the vehicle interior, a solar radiation sensor 23 that detects the amount of solar radiation irradiated into the vehicle interior, The post-evaporator sensor 24 that detects the air temperature immediately after passing through the refrigerant evaporator 7, the vehicle speed sensor 26 that detects the vehicle speed, and the water temperature sensor 27 that detects the temperature of the hot water circulating in the heater core 7 are connected to the input. An air conditioning operation panel 25 is input to the control device 20.
[0021]
The air conditioning operation panel 25 is provided with a temperature setter 25a for setting a desired temperature Tset in the passenger compartment and an inside / outside air changeover switch 25b for switching the inside / outside air mode by manual operation.
The control device 20 is a well-known device having an A / D converter, a microcomputer, etc. (not shown) inside, and signals from the sensors 21 to 24 are A / D converted by the A / D converter. After that, it is configured to be input to the microcomputer. .
[0022]
The microcomputer is a well-known computer having a CPU, ROM, RAM, I / O, etc. (not shown), and power is supplied from the battery 28 when the ignition switch 27 of the engine is turned on.
Next, the operation of the present embodiment will be described based on the flowchart of FIG.
First, when the air conditioner automatic control processing is started in step 100, first, in step 200, initialization processing of data and flags used for the subsequent processing is performed.
[0023]
In step 300, the values (Tr, Tam, Ts, Te, Sp, Tw, Tset) obtained by A / D converting the signals from the sensors 21 to 24, 26, 27 and the air conditioning operation panel 25 are obtained. Read. Tr is a signal from the inside air sensor 21, Tam is a signal from the outside air sensor 22, Ts is a signal from the solar radiation sensor 23, Te is a signal from the post-evaporator sensor 24, Vc is a signal from the vehicle speed sensor 26, Tset is a signal from the temperature setter 25a, and Tw is a signal from the water temperature sensor 27.
[0024]
Next, in step S400, vehicle speed correction in the inside air mode, which is the main part of the present invention, is performed, but a detailed description will be given later.
Subsequently, at step 500, the required blowing temperature (TAO) of the air blown into the vehicle interior is calculated based on the various data stored in the RAM and the following formula 1 stored in the ROM.
[0025]
[Expression 1]
TAO = Kset * Tset-Kr * Tr-Kam * Tam-Ks * Ts + Trv + C
Kset, Kr, Kam, Ks, C are constants for correction, and Trv is a vehicle speed correction term set in step S400.
Next, at step 600, the blower voltage BLW to be applied to the blower 6 is determined. The blower voltage BLW is determined from the characteristics shown in FIG. 3 stored in the TAO and ROM.
[0026]
Next, at step 700, the outlet mode is determined from the TAO and the characteristics shown in FIG. 4 stored in the ROM. Here, the face (FACE) mode is a mode in which cool air is mainly blown out from the face outlet toward the upper body of the occupant, and the foot mode (FOOT) is mainly directed from the foot outlet to the feet of the occupant. The bi-level (B / L) mode is a mode in which mainly cool air is blown from the face air outlet, and hot air is mainly blown from the foot air outlet.
[0027]
Next, at step 800, it is determined whether to turn on or off the electromagnetic clutch 11a from the detection value Te of the post-evaporator sensor 24 and the characteristics shown in FIG. 5 stored in the ROM.
In step 900, the target opening .theta.0 of the air mix door 17 is calculated based on the various data stored in the RAM and the following mathematical formula 2 stored in the ROM.
[0028]
[Expression 2]
θ0 = {(TAO−Te) / (Tw−Te)} × 100 (%)
Next, in step 1000, a control signal is output to each actuator so that the control value determined in steps 700 to 900 is obtained.
Then, in step 1100, it is determined whether or not a predetermined cycle time τ has elapsed since the execution of the process of step 1200, and the next process is not performed until it is determined that the result of this determination is YES.
[0029]
Next, the contents of step 400, which is the main part of the present invention, will be described in detail. FIG. 6 is a flowchart showing the control contents of step 400.
First, in step 401, the inside / outside air mode is determined based on the characteristics stored in the TAO and ROM shown in FIG.
Next, in step 402, it is determined whether the inside / outside air mode determined in step 401 is the inside air mode. Here, since the inside / outside air mode can be set manually by the inside / outside air changeover switch 25b, it is determined in step S401 whether the inside / outside air changeover switch 25b is included or not, and whether or not it is the inside air mode. Yes.
[0030]
If the result of determination in step S402 is NO and the outside air mode is set, the process proceeds to step 404. In step S404 , the vehicle speed correction term Trv is set to zero. On the other hand, if the determination result in step S402 is YES and the inside air mode is set, the process proceeds to step 403, and in step 403, the vehicle speed correction term Trv is calculated. Here, the vehicle speed correction term Trv is calculated by Equation 3 below.
[0031]
[Equation 3]
Vehicle speed correction term Trv = Kvc × Frv
Further, Kvc in the equation 3 is determined from the vehicle speed Vc and the characteristic chart stored in the ROM as shown in FIG. Moreover, FRV, based on the difference between the inner air temperature Tr and the outside air temperature Tam, as shown in FIG. 9, is determined from the stored characteristic diagram above ROM.
[0032]
More specifically, as shown in FIG. 8, Kvc is 0 when the vehicle speed Vc is 0, and increases as the vehicle speed Vc increases when the vehicle speed Vc is 0 to 100 km / h, and when the vehicle speed Vc is 100 km / h. 1 When the vehicle speed Vc is faster than 100 km / h, Kvc becomes constant.
As shown in FIG. 9, Frv becomes 0 when the difference between the inside temperature Tr and the outside temperature Tam is 0 ° C. Frv becomes negative when the difference between the internal temperature Tr and the external temperature Tam is lower than 0 ° C., that is, when the temperature of the external air is higher than that of the internal air, and gradually increases in the range of 0 to −10 ° C. Is set to a small value.
[0033]
Further, Frv becomes positive when the difference between the inside temperature Tr and the outside temperature Tam is higher than 0 ° C., that is, when the temperature of the inside air becomes higher than the outside air, and gradually increases in the range of 0 to 10 ° C. It is set large. For example, since the outside temperature Tam is higher than the inside temperature Tr when the passenger compartment is cooled in summer, Frv is calculated to be larger as the difference between the inside temperature Tr and the outside temperature Tam increases. When the vehicle travels in such a state, Kvc is calculated to be larger as the vehicle speed Vc increases.
[0034]
For example, if the difference is −10 ° C., Frv is −5 ° C. and the vehicle speed Vc is 100 km / h, Kvc is 1. Therefore, in this case, the vehicle speed correction term Trv is calculated as -5 by -5 × 1. Since this vehicle speed correction term Trv is calculated by the above equation 1 in step 500, the required blowout temperature TAO is calculated so as to be 5 ° C. lower than when the vehicle speed Vc is 0 and the difference is 0. Is done. As a result, the air mix door 17 controls the temperature of the conditioned air to be lowered.
[0035]
In other words, in the inside air mode, as the vehicle speed Vc increases, the amount of outside air that is not air-conditioned from the gap in the manufacture of the vehicle increases. In some cases, the occupant feels uncomfortable due to the outside air entering the vehicle interior. The unpleasant sensation varies depending on the internal temperature Tr at that time, and increases as the difference between the internal temperature Tr and the external temperature Tam increases.
[0036]
Therefore, in the present embodiment, the required blowing temperature TAO is calculated so as to decrease as the vehicle speed Vc increases and the difference between the internal temperature Tr and the external temperature Tam increases. The influence of outside air can be satisfactorily canceled, comfortable air conditioning control can be performed, and the air conditioning feeling of the occupant can be improved.
[0037]
On the other hand, for example, when the passenger compartment is heated in winter, the internal temperature Tr is higher than the external temperature Tam. Therefore, the larger the difference between the internal temperature Tr and the external temperature Tam, the larger the Frv is calculated. When the vehicle travels in such a state, Kvc is calculated to be larger as the vehicle speed Vc increases.
For example, if the difference is 10 ° C., Frv is 5 ° C., and if the vehicle speed Vc is 100 km / h, Kvc is 1. Therefore, in this case, the vehicle speed correction term Trv is calculated as 5 by 5 × 1.
[0038]
Since the vehicle speed correction term Trv is calculated by Equation 1 in step 500, the required blowing temperature TAO is 5 ° C. higher than when the vehicle speed Vc is 0 and the difference is 0. Is calculated. As a result, the temperature of the conditioned air is controlled by the air mix door 17 to be high.
That is, of course, even in winter, as the vehicle speed Vc increases, the amount of outside air that is not air-conditioned from the gaps in the manufacture of the vehicle increases. As a result, discomfort is given to the occupant by the outside air entering the vehicle interior, and the discomfort increases as the difference between the inside temperature Tr and the outside temperature Tam increases.
[0039]
Therefore, in the present embodiment, the required blowing temperature TAO is calculated so as to increase as the vehicle speed Vc increases and the difference between the internal temperature Tr and the external temperature Tam increases. The influence of the outside air to be canceled can be satisfactorily canceled, comfortable air conditioning control can be performed, and the air conditioning feeling of the occupant can be improved.
[0040]
In the present embodiment, as is clear from Equation 3 and FIG. 8, regardless of the season, it is possible to satisfactorily cancel the intrusion of the outside air according to the difference between the inside temperature Tr and the outside temperature Tam and perform the air conditioning control well. And the air conditioning feeling of the passenger can be improved. If it is determined in step 402 that the outside air mode is selected and the process proceeds to step S404, in the outside air mode, there is no problem that outside air that is not air-conditioned enters through the gap of the vehicle, so the vehicle speed correction term Trv is set to 0. It is as.
[0041]
(Second Embodiment)
The present embodiment is different from the first embodiment in the contents of steps 400 to 600. In the first embodiment, the necessary blowout temperature TAO is corrected based on the vehicle speed Vc, the internal air temperature Tr, and the external air temperature Tam. In this embodiment, however, the blower voltage is corrected in this embodiment. is there.
[0042]
First, FIG. 10 shows a flowchart showing the control contents in step 400. Since step 401 and step 402 are the same as those in the first embodiment, description thereof will be omitted.
If it is determined in step 402 that the outside air mode is selected, a blower correction term FrvL = 0 described later is set in step S406. On the other hand, if the inside air mode is determined in step 402, the blower correction term FrvL is calculated in step S405. The calculation process in step 405 will be described later.
[0043]
Next, step S500 calculates the required blowing temperature TAO by the following numerical formula 4.
[0044]
[Expression 4]
TAO = Kset * Tset-Kr * Tr-Kam * Tam-Ks * Ts + C
Kset, Kr, Kam, Ks, and C are correction constants.
In step 600, the blower voltage BLW ′, which is the final target air blowing amount in the arithmetic processing, is calculated by the following formula 5.
[0045]
[Equation 5]
Blower voltage BLW '= BLW + Kvc x FrvL
Here, BLW is a blower voltage determined from the characteristics of FIG. 3, and Kvc is a correction coefficient determined from the characteristics of FIG. The blower correction FrvL is determined from the characteristic diagram stored in the ROM shown in FIG.
In other words, as described above, when the outside air mode is determined in step 402, FrvL is set to 0 in step 406, so the blower voltage BLW ′ is determined as it is from FIG.
[0046]
On the other hand, if the inside air mode is determined in step 402 as described above, in step 405, the characteristics shown in FIG. 11 are determined. Specifically, the larger the absolute value of the difference between the inside temperature Tr and the outside temperature Tam, the larger the setting. Therefore, Kvc × FrvL is set larger as the absolute value becomes larger and the vehicle speed Vc becomes faster. As a result, as the absolute value increases and the vehicle speed Vc increases, the final blower voltage BLW ′ is set higher.
[0047]
As described above, in this embodiment, only the blower voltage is corrected based on the vehicle speed Vc and the absolute value of the difference between the internal temperature Tr and the external temperature Tam, and as the vehicle speed Vc increases and the absolute value increases. The blower voltage was increased. Also by this, it is possible to satisfactorily cancel the influence of the outside air entering from the gap of the vehicle, and comfortable air conditioning control can be performed. As a result, the passenger's air conditioning feeling can be improved.
[0048]
Further, the present embodiment has the following operational effects. In the first embodiment, when the required blowout temperature TAO fluctuates due to fluctuations in the vehicle speed Vc, for example, the blowout outlet mode is frequently switched as shown in FIG. As a result, hunting such as the air mix door 17 and the air outlet mode occurs. However, since the blower voltage is corrected in the present embodiment, it is possible to prevent such hunting in the outlet mode.
[0049]
(Other embodiments)
In the first embodiment, as shown in FIG. 9, Frv is determined by the difference between the internal temperature Tr and the external temperature Tam. However, as shown in FIG. 12, the Frv is set higher as the external temperature becomes higher. May be.
In the second embodiment, FrvL is determined by the absolute value of the difference between the internal temperature Tr and the external temperature Tam as shown in FIG. 11, but FrvL is determined according to the external temperature Tam as shown in FIG. You may decide.
