Abstract

<P>PROBLEM TO BE SOLVED: To control air conditioning based on the detection of influence of the solar radiation by a simple system. <P>SOLUTION: The temperature of each portion in the cabin is detected by a non-contact temperature sensor. First air conditioning correction values f1, f5 are calculated according to a magnitude relation of the temperature difference (TSWDr-TSWPa) of the right and left side windows and the magnitude. For the target blow-off temperature calculated every air conditioning zone, a Dr side is corrected by the first air conditioning correction value f1 which is increased as the temperature of the side window at the Dr side rises, and a Pa side is corrected by the first air conditioning value f5 which is increased as the temperature of the side window at the Pa side rises.

Description

  The present invention relates to a vehicle air conditioner that automatically controls the air conditioning capability in accordance with changes in a set temperature and an air conditioning load in a passenger compartment.

Conventionally, a temperature distribution around an occupant in a passenger compartment is finely measured by a matrix IR (infrared ray) sensor, which is a non-contact temperature detecting means, and is generated as a thermal image, and the size and direction of solar radiation by pattern processing of the thermal image There are some which perform the air conditioning control by estimating the influence of the above (for example, see Patent Document 1).
JP-A-10-230728

  However, in the above prior art, in order to grasp the solar radiation distribution from the thermal image, a large number of pixels of the matrix IR sensor are required, and both the sensor element itself and its image processing apparatus are complicated and expensive. . Further, since the image processing result is used for air conditioning control, the air conditioning control is complicated, and it is difficult to ensure the reliability of the entire system as an air conditioning apparatus.

  An object of this invention is to detect the influence of solar radiation with a simple system in view of the said point, and to perform air-conditioning control based on this.

  In order to achieve the above object, the first feature of the present invention is that the temperature detection means (7Fr, 7Rr) has windows (100a, 100b, 100c, 100d, 90Fr, 90Rr) and / or the temperature in the vicinity (101a, 101b, 101c, 101d, 91Fr, 91Rr) of a window in a different direction, and the air conditioning control means (8) calculates the detected temperature difference. The air conditioning correction values (f1, f5, f1b, f5b, f1c, f5c, f1d, f5d, FrSunDr, FrSunPa, RrSunDr, RrSunPa) for correcting the air conditioning load according to the temperature difference are calculated and this air conditioning correction is performed. The air conditioning state is corrected based on the value.

  The vehicle is provided with windows in four directions, that is, right and left side windows, left and right front and rear side windows, a front front window, and a rear rear window.

  By the way, when the solar radiation directly hits the window in the certain direction of the vehicle and in the vicinity of the window, the temperature of the window and the vicinity of the window rises accordingly. At this time, passengers close to this window feel the heat due to the effects of solar radiation.

  Therefore, of these, compare the temperature of the respective windows and / or the temperature of the interior part in the vicinity of the window in different directions of the vehicle, for example, right and left, front and rear, or front and right or left. Thus, the direction of solar radiation can be grasped, and the intensity of solar radiation can be grasped by the temperature difference between them.

  Then, if an air conditioning correction value for correcting the air conditioning load is calculated based on the temperature difference between the windows in the different directions and / or the vicinity of the window, the air conditioning correction value includes the thermal sensation of the passengers affected by solar radiation. Correlation can be provided. Therefore, by correcting the air-conditioning state according to the air-conditioning correction value, it is possible to perform comfortable air-conditioning control according to the passenger's sense of temperature.

  Further, when detecting the window in the different direction and the temperature in the vicinity thereof, the temperature distribution in that direction is not detected, so that a large number of IR sensor pixels are not required as temperature detecting means, and a simple system can be obtained.

  Note that various combinations of the windows in different directions and / or the vicinity of the windows are possible as follows. (A) Side windows (100a, 100c) on the right side of the vehicle and side windows (100b, 100d) on the left side, (b) At least one side window (100a, 100b) on the right side and left side of the vehicle, A front window (90Fr), (c) at least one side window (100c, 100d) on the right and left sides of the vehicle, a rear window (90Rr) behind the vehicle, and (d) a front window (90Fr) in front of the vehicle. Rear rear window (90Rr), (e) Interior of vehicle right side window (100a, 100c) and right side window (101a, 101c), left side window (100b, 100d) of vehicle, and left side window Interior (101b, 101d), F) At least one side window (100a, 100b) on the right side and left side of the vehicle and an instrument panel (91Fr) in the vicinity of the front window (90Fr), (G) At least one side window (100c, 100d) and a rear tray (91Rr) in the vicinity of the rear window (90Rr), (ku) at least one of the right and left side windows (100a, 100b) of the vehicle, and an interior (101a, 101) in the vicinity of the side window and the front Window (90Fr), (K) At least one of the right and left side windows (100c, 100d) of the vehicle and the interior (101c, 101d) and rear window (90Rr), (ko) of the vehicle in the vicinity of the side window At least one of the side windows and the left side windows (100a, 100b), the interior (101a, 101b) in the vicinity of the side window, the instrument panel (91Fr) in the vicinity of the front window, (S) at least on the right side and the left side of the vehicle One of the side windows (100c, 100d), the interior (101c, 101d) in the vicinity of the side window, the rear tray (91Rr) in the vicinity of the rear window, and the like.

  The second feature of the present invention is that the first air conditioning correction value (f1) calculated in accordance with a window in a different direction or a temperature difference in the vicinity thereof when it is determined that all window windows that can be opened and closed are fully closed. F5, f1a, f5a, f1b, f5b, f1c, f5c, f1d, f5d), and the window glass is not fully closed, that is, at least one window glass is opened. If it is determined, the third air conditioning correction value (f8, f9, f8a, f9a, f8b) calculated according to the difference between the temperature of the part where the temperature rise is large due to solar radiation and the temperature of the part where the temperature rise is small. , F9b), the air conditioning state is corrected.

  Thereby, in the fully closed state, an air conditioning state based on the first air conditioning correction value considering the direction and intensity of solar radiation can be realized. If not in the fully closed state, a part where the temperature rise due to solar radiation is large and a part where the temperature rise is small The temperature difference accurately reflects the air conditioning load on the side where the window glass is not opened. If the air conditioning state is corrected by the third air conditioning correction value due to this temperature difference, the window glass will be opened. The air conditioning correction for solar radiation and cold radiation can be performed with high accuracy on the side that is not.

  Note that the window glass is fully closed when all the windows are in the low temperature range or the high temperature range outside the intermediate temperature range when the outside temperature detected by the outside temperature sensor (81) as the outside environment of the vehicle is in the temperature range. It can be determined that the glass is in a fully closed state. That is, during normal use, when the outside air temperature is in a low temperature range (for example, 10 ° C. or lower), the occupant is in a state of heating the passenger compartment, and the outside air temperature is in a high temperature range (for example, 30 ° C. or higher). In the case of temperature, it can be considered that the window glass is fully closed in order to cool the passenger compartment. Conversely, when the outside air temperature is in the intermediate temperature range, the occupant may open the window glass to take in a large amount of fresh outside air. Whether or not the window glass is in a fully closed state can be determined based on the outside air temperature.

  The third feature of the present invention is that the air-conditioning control means sets the lowest temperature in one direction among the temperatures of the plurality of windows in one direction among the detected parts in two different directions detected by the temperature detection means. The temperature is to be detected.

  When an object having a higher temperature than the window temperature such as an occupant exists near the window to be measured, the temperature of the window may not be an accurate temperature. Therefore, by extracting the lowest temperature from the temperatures at a plurality of locations in the window and using this as the window temperature, an accurate window temperature can be detected.

  According to a fourth feature of the present invention, the air conditioning control means calculates a second air conditioning correction value for increasing heating according to the detected temperature of the detected portion, and sets the air conditioning state according to the second air conditioning correction value. It is to correct.

  The detected temperature of the detected part, that is, the window or the interior part in the vicinity of the window reflects the degree of influence of the cold radiation on the passenger in the vicinity. Therefore, the second air conditioning correction value (f2, f7) for increasing the heating according to the temperature of the window or the interior part near the window is calculated, and the air conditioning state is corrected based on the second air conditioning correction value. Thus, it is possible to realize an air conditioning state that matches the occupant's warm feeling.

  The second air conditioning correction value can be calculated so as to become smaller as the influence of solar radiation on the vehicle interior determined according to the detected window temperature increases. That is, the window temperature reflects the degree of cold radiation. However, if the influence of solar radiation increases, the window temperature increases accordingly, and as a result, the degree of influence of cold radiation decreases. Therefore, if the window temperature rises, the second air conditioning correction value is decreased to reduce the heating intensity, thereby preventing the face from being burned by overcorrection.

  According to a fifth feature of the present invention, the air conditioning control means corrects the temperature of the window detected by the temperature detection means in accordance with a change in temperature of a part affected by solar radiation other than the window detected by the temperature detection means. It is to be.

  According to this, the window temperature that takes time until the temperature rises and stabilizes after the solar radiation hits is corrected according to the temperature change of the part where the temperature rises with good response under the influence of solar radiation other than the window Thus, the window temperature can be adapted to the change in the sensation of the passenger affected by the solar radiation, and air conditioning suitable for the sensation of the occupant can be performed.

  The sixth feature of the present invention is that the air conditioning capability on the window side is set to be higher than the air conditioning capability on the center side of the vehicle. Thereby, the air-conditioning capability on the window side that is easily affected by solar radiation or cold radiation can be enhanced, and air conditioning that matches the sensation of the passenger can be performed.

  Specifically, the side face air outlets (2a, 2b, 2c, 2d) that blow the air conditioned air toward the window side rather than the center face air outlets (20a, 20b, 20c, 20d) that blow the air conditioned air toward the center side. The air conditioning capacity can be set high. Or the sheet | seat air conditioner (200) which ventilates from several blower outlets (206a, 206b, 207a, 207b) of a sheet | seat skin is provided, and the air conditioning of the blower outlet of the window side rather than the center side is carried out among the blower outlets of this sheet | seat skin. Ability can be set high. In this case, as the air conditioning capacity, it is conceivable to increase the amount of air blown from the air outlet, or to lower the air temperature at the cooling side or higher at the heating side.

  The seventh feature of the present invention is that when the temperature detecting means detects the temperature of the window, the temperature at the bottom of the window (A2, B2, C2, D2, A11, B11, C11, D11, A12, B12, C12, D12). ) Is detected. As a result, when there are smokers among the passengers, only the upper part of the window may be opened for ventilation, but even at this time, if the temperature of the lower part of the window is detected, it can be accurately detected as the window temperature. it can.

  In addition, the code | symbol in the bracket | parenthesis of each means described in a claim and this column shows the correspondence with the specific means as described in embodiment mentioned later.

  The inside air temperature sensors 84 and 85 are respectively disposed in front and rear of the vehicle interior, detect the air temperatures on the Fr side and the Rr side in the vehicle interior, and respectively output the inside air temperature signals TrFr and TrRr corresponding to the detected temperatures. It outputs to ECU8.

  The evaporator temperature sensor 86 detects the blown air temperature of the evaporator 53 and outputs an evaporator blown temperature signal TeFr corresponding to the detected temperature to the air conditioner ECU 8. The evaporator temperature sensor 87 is the blown air temperature of the evaporator 63. And outputs an evaporator outlet temperature signal TeRr corresponding to the detected temperature to the air conditioner ECU 8.

  In addition, the air conditioner ECU 8 includes temperature setting switches 9, 10, 11, and 12 in which the desired temperatures TsetFrDr, TsetFrPa, TsetRrDr, and TsetRrPa of the air conditioning zones 1 a, 1 b, 1 c, and 1 d are set by the occupant. Each non-contact temperature sensor 7Fr, 7Rr for detecting the surface temperature of each part of 1a, 1b, 1c, 1d is connected. In the vicinity of the temperature setting switches 9, 10, 11, 12, there are provided displays 9 a, 10 a, 11 a, 12 a as desired temperature display means for displaying the set contents such as the desired temperature.

  The non-contact temperature sensor 7Fr for Fr and the non-contact temperature sensor 7Rr for Rr use a so-called matrix IR in which a thermopile detection element that detects an electromotive force change corresponding to a change in the amount of input infrared rays as a temperature change is used. Sensors for Fr and Rr have the same configuration. Below, Fr non-contact temperature sensor 7Fr is demonstrated.

  As shown in FIG. 4, the non-contact temperature sensor 7Fr is a sensor chip in which a lens 75 that collects infrared rays from each detected portion and a plurality of sensor elements that detect incident infrared rays are arranged in a matrix. 70a, 70b, an electronic circuit 77 for processing output signals from the sensor chips 70a, 70b, and a connector 78 for outputting an electric signal from the electronic circuit 77 to the air conditioner ECU 8.

  As shown in FIG. 5, the non-contact temperature sensors 7Fr and 7Rr are disposed on the left and right center vehicle interior ceilings of the Fr side occupant and the Rr side occupant. Infrared rays from the window 90Fr to the side windows 100a and 100b on the Fr side and the side windows 100c and 100d on the Rr side to the rear window 90Rr can be condensed, that is, a detection range.

  In the first embodiment, the detected portions of the non-contact temperature sensors 7Fr and 7Rr are exemplified as matrix detection ranges on the Dr side in FIGS. 6 (a) and 6 (b), respectively. It is set as shown by the positional relationship seen from. 6 and 7, the detected parts are denoted as A1, A2,..., And the temperatures of the detected parts described later are also denoted as A1, A2,. In any of the following embodiments, the detection range and the temperature in the range are the same notation.

  In other words, in the first embodiment, the Fr non-contact temperature sensor 7Fr has two surface temperatures A1 and A2 in the vertical direction of the side window 100a on the FrDr side and the temperature A5 of the abdomen of the FrDr occupant on the FrDr side. As the detected portion, and the surface temperatures B1 and B2 in the vertical direction of the side window 100b on the FrPa side at the left-right symmetrical position of the vehicle, and the temperature B5 of the abdomen of the FrPa occupant as the detected portion on the FrPa side Each is set and arranged.

  Similarly, in the first embodiment, the Rr non-contact temperature sensor 7Rr is configured to calculate the surface temperatures C1 and C2 at two locations in the vertical direction of the side window 100c on the RrDr side and the temperature C5 of the abdomen of the RrDr occupant on the RrDr side. And two surface temperatures D1 and D2 in the vertical direction of the side window 100d on the RrPa side at the left-right symmetrical position of the vehicle and the temperature D5 of the abdomen of the RrPa occupant are detected on the RrPa side. Are set and arranged respectively.

  In the first embodiment, by setting the temperature detection portions of each side window 100a, 100b, 100c, and 100d to two locations, even if the face or hand of a passenger with high temperature enters the detection range of each sensor cell, The reliability of the detected value is increased.

  In addition, since the surface temperatures A2, B2, C2, and D2 at the lower part of the windows are detected as the temperature detection portions of the side windows 100a, 100b, 100c, and 100d, respectively, for the ventilation of the passenger compartment due to the smoking of passengers. Even if any one of the side windows 100a, 100b, 100c, and 100d is opened, glass is present in the lower part of the window, and therefore it can be accurately detected as the window temperature.

  The air conditioner ECU 8 is a well-known one that includes an analog / digital converter, a microcomputer, and the like. Each non-contact temperature sensor 7Fr, 7Rr, each temperature sensor 81, 82, 84, 86, 87, and temperature setting. The output signals output from the switches 9, 10, 11, and 12 are analog / digital converted by an analog / digital converter and input to the microcomputer.

  The microcomputer is a well-known computer composed of a memory such as a ROM and a RAM, a CPU (Central Processing Unit), and the like, and is supplied with power from a battery (not shown) when an ignition switch is turned on.

  Next, the operation of the first embodiment in the above configuration will be described.

  When the power is turned on, the air conditioner ECU 8 starts a control program (computer program) stored in the memory, and executes an air conditioning control process according to the main routine shown in FIG. Here, the front seat air-conditioning process and the rear seat air-conditioning process are executed alternately, and the front seat air-conditioning process and the rear seat air-conditioning process are executed every certain period Ts (specifically, 250 ms). Is done. Hereinafter, the front seat air conditioning process and the rear seat air conditioning process will be described separately with reference to FIG.

<Front seat air conditioning>
First, the front seat air conditioning process will be described. Since the FrDr side and the FrPa side are respectively processed, the following description will mainly focus on the air-conditioning zone 1a on the FrDr side, and the description on the air-conditioning zone 1b on the FrPa side will be simplified.

  First, in step S121, set temperature signals TsetFrDr and TsetFrPa are read from the temperature setting switches 9 and 10. Further, in step S122, the outside air temperature signal Tam is read from the outside air temperature sensor 81, and the inside air temperature TrFr is read from the inside air temperature sensor 84. Further, the detected temperature signals A1, A2, A5, B1, B2, B5 and C1, C2, C5, D1, D2, D5 of the detected part are read from the non-contact temperature sensors 7Fr, 7Rr.

  Next, in step S123, the set temperature signal TsetFrDr, the outside air temperature signal Tam, and the inside air temperature signal TrFr are substituted into Equation 1 to calculate the target blowing temperature TAOFrDr of the air blown into the vehicle interior. This target blowing temperature TAOFrDr is a target temperature required to maintain the temperature of the FrDr-side air-conditioning zone 1a at the set temperature TsetFrDr regardless of changes in vehicle environmental conditions (air-conditioning heat load conditions). The amount corresponds to the load.

TAOFrDr = KsetFr × TsetFrDr−KrFr × TrFr
−KamFr × Tam−CFr + f10 + f2
... (Formula 1)
Note that KsetFr, KrFr, and KamFr are the gain of each signal, and CFr is a constant. Further, f10 and f2 are correction values for correcting the target blowing temperature according to the temperature of each detected part detected by the non-contact temperature sensors 7Fr and 7Rr, and details will be described later.

  Similarly, the outside air temperature signal Tam, the set temperature signal TsetFrPa, and the inside air temperature TrFr are substituted into Equation 2 to calculate the target blowing temperature TAOFrPa of the air blown into the vehicle interior. This target blowing temperature TAOFrPa is a target temperature required to maintain the temperature of the FrPa-side air conditioning zone 1b at the set temperature TsetFrPa, and is an amount corresponding to the air conditioning load of the air conditioning zone 1b.

TAOFrPa = KsetFr × TsetFrPa−KrFr × TrFr
-KamFr × Tam-CFr + f11 + f7
... (Formula 2)
Note that KsetFr, KrFr, and KamFr are the gain of each signal, and CFr is a constant. Further, f11 and f7 are correction values for correcting the target blowing temperature according to the temperatures of the respective detected parts detected by the non-contact temperature sensors 7Fr and 7Rr, and details will be described later.

  Next, in step S124, based on the average value of TAOFrDr and TAOFrPa (= (TAOFrDr + TAOFrPa) / 2, hereinafter referred to as Fr target average value), the inside / outside air mode is determined by the control map of FIG. In FIG. 9, SW1 is the target opening degree of the inside / outside air switching door 51, and the target opening degree SW1 is changed to continuously switch between the inside air mode (inside air 100%) and the outside air mode (outside air 100%). . By switching the inside / outside air switching door 51, the inside air (inside air) is introduced from the inside air introduction port 50a in the inside air mode (inside air circulation mode), and the outside of the vehicle compartment is introduced from the outside air introduction port 50b in the outside air mode (outside air introduction mode). Air (outside air) is introduced.

  Specifically, as shown in FIG. 9, in a region where the Fr target average value (corresponding to TAO in FIG. 9) is equal to or lower than a predetermined temperature (maximum cooling region), the inside / outside air switching door 51 causes the inside air inlet port to enter. When the inside air circulation mode in which 50a is fully opened and the outside air introduction port 50b is fully closed is selected and the Fr target average value becomes higher than a predetermined temperature, the outside air introduction port 50b is fully opened by the inside / outside air switching door 51, and the inside air introduction port 50a is opened. Select the outside air introduction mode that fully closes. Further, when the Fr target average value (TAO) is in an intermediate temperature range, the inside / outside air mode is set to the inside / outside air mixing mode in which both the inside air and the outside air are introduced simultaneously.

  Next, in step S125, the air outlet mode is individually determined for the Fr-side air conditioning zones 1a and 1b in FIG. FIG. 10 is a control map for determining the air outlet mode stored in advance in the ROM. In this example, as TAOFrDr (corresponding to TAO in FIG. 810) rises, the air outlet mode of the air conditioning zone 1a is changed to the face mode. (FACE) mode → bilevel (B / L) mode → foot (FOOT) mode is automatically switched sequentially. Further, as TAOFrPa (corresponding to TAO in FIG. 10) rises, the air outlet mode of the air-conditioning zone 1b is automatically automatically switched from the face (FACE) mode to the bi-level (B / L) mode to the foot (FOOT) mode. It is supposed to switch to.

  Here, the face mode is a mode in which conditioned air is blown out only from the face outlet, and the foot mode is a mode in which conditioned air is blown out only from the foot outlet. The bi-level mode is a mode in which conditioned air is blown out from the face air outlet and the foot air outlet.

  For example, in the face mode, the face air outlets 2a and 20a (2b and 20b) are opened at the air outlet switching door 56a (56b), and the conditioned air flows from the face air outlets 2a and 20a (2b and 20b) only in the vehicle interior. Blow out toward the upper body of the passenger. In the bi-level mode, the face outlets 2a, 20a (2b, 20b) and the foot outlet (not shown) are opened at the outlet switching door 56a (56b), and the conditioned air is supplied to the face outlets 2a, 20a (2b). 20b) and the foot outlet, the air is blown out simultaneously to the passenger's upper body side and passenger's lower body side in the passenger compartment. In the foot mode, the foot outlet is fully opened at the outlet switching door (not shown), and the conditioned air is mainly blown out from the foot outlet toward the passenger's lower body side.

  As described above, when the air outlet zone is determined for each air conditioning zone, each servo motor of each air outlet switching door is controlled for each air conditioning zone so that the air outlet mode determined for each air conditioning zone is set. Open and close the air outlet switching doors.

  Next, in step S126, the blower voltage to be applied to the blower motor 52a is determined based on the above-described Fr target average value (average value of the target blowing temperature TAOFrDr and TAOFrPa). The blower voltage is for controlling the air volume of the blower 52, and is determined according to the control map of FIG. 11 stored in advance in the ROM based on the Fr target average value.

  In the control map of FIG. 11, when TAO in FIG. 11 corresponds to the target average value for Fr and this average value (= TAO) is in the intermediate region, the blower voltage (that is, the air volume of the blower 52) becomes a constant value. When TAO is larger than the intermediate region, the blower voltage (that is, the air volume of the blower 52) increases as the TAO increases. When TAO is smaller than the intermediate region, the blower voltage (that is, the air volume of the blower 52) decreases as TAO decreases. In this way, the blower voltage is determined.

  Next, in step S127, target opening degrees θ1 and θ2 of the air mix doors 55a and 55b are calculated by the following mathematical formulas 3 and 4.

θ1 = {(TAOFrDr−TeFr) / (Tw−TeFr)} × 100 (%)
... (Formula 3)
θ2 = {(TAOFrPa−TeFr) / (Tw−TeFr)} × 100 (%)
... (Formula 4)
In Equations 3 and 4, TeFr is an evaporator outlet temperature signal of the evaporator temperature sensor 86, and Tw is a cooling water (hot water) temperature signal of the cooling water temperature sensor 82. θ1 = 0% and θ2 = 0% are maximum cooling positions, and in the FrDr side passage 50c and the FrPa side passage 50d, the entire amount of air (cold air) after passing through the evaporator 53 on the Fr side flows through the bypass passages 51a and 51b. . Further, θ1 = 100% and θ2 = 100% are maximum heating positions, and the entire amount of air (cold air) after passing through the evaporator 53 on the Fr side flows into the core heater 54 in the FrDr side passage 50c and the FrPa side passage 50d. Heated.

  Control signals indicating the inside / outside air switching mode, the target opening θ1, θ2, the outlet mode, and the blower voltage determined as described above are output to the servo motors 510a, 550a, 550b, 560a, 560b, the blower motor 52a, and the like. Then, each operation of the inside / outside air switching door 51, the air mix doors 55a and 55b, the outlet switching doors 56a and 56b, the blower 52, etc. is controlled (step S128).

  Thereafter, when a certain period of time elapses in step S129, the process returns to step S121, and the above-described air conditioning control process (steps S121 to S129) is repeated. By repeating such calculation and processing, the air conditioning of the air-conditioning zones 1a and 1b on the Fr side is automatically controlled.

<Rear seat air conditioning treatment>
Next, the rear seat air conditioning process will be described. Also in the rear seat air conditioning process, the air conditioning process is performed by the control routine shown in FIG.

  First, in step S121, set temperature signals TsetRrDr and TsetRrPa are read from the temperature setting switches 11 and 12. In step S122, the outside air temperature signal Tam is read from the outside air temperature sensor 81, and the inside air temperature TrRr is read from the inside air temperature sensor 85. Further, the detected temperature signals A1, A2, A5, B1, B2, B5 and C1, C2, C5, D1, D2, D5 of the detected part are read from the non-contact temperature sensors 7Fr, 7Rr.

  Next, in step S123, the set temperature signal TsetRrDr, the outside air temperature signal Tam, and the inside air temperature signal TrRr are substituted into Equation 5 to calculate the target blowing temperature TAORrDr of the air blown into the vehicle interior. This target blowing temperature TAORrDr is a target temperature required to maintain the temperature of the RrDr-side air conditioning zone 1c at the set temperature TsetRrDr regardless of changes in vehicle environmental conditions (air conditioning thermal load conditions), and air conditioning in the air conditioning zone 1c. The amount corresponds to the load.

TAORrDr = KsetRr × TsetRrDr−KrRr × TrRr
−KamRr × Tam−CRr + f10 + f2
... (Formula 5)
Note that KsetRr, KrRr, and KamRr are the gain of each signal, and CRr is a constant. Further, f10 and f2 are correction values for correcting the target blowing temperature according to the temperatures of the detected parts detected by the non-contact temperature sensors 7Fr and 7Rr as described above.

  Similarly, the outside air temperature signal Tam, the set temperature signal TsetRrPa, and the inside air temperature TrRr are substituted into Equation 6 to calculate the target blowing temperature TAORrPa of the air blown into the vehicle interior. This target blowing temperature TAORrPa is a target temperature required to maintain the temperature of the RrPa-side air conditioning zone 1d at the set temperature TsetRrPa, and is an amount corresponding to the air conditioning load of the air conditioning zone 1d.

TAORrPa = KsetRr × TsetRrPa−KrRr × TrRr
−KamRr × Tam−CRr + f11 + f7
... (Formula 6)
Note that KsetRr, KrRr, and KamRr are the gain of each signal, and CRr is a constant. Further, f11 and f7 are correction values for correcting the target blowing temperature according to the temperatures of the detected parts detected by the non-contact temperature sensors 7Fr and 7Rr as described above.

  Next, without executing the determination process of the inside / outside air mode (step S124) (this is because the outside air mode is not set in the rear seat air conditioning), the determination process of the outlet mode is performed in the next step S125. Execute.

  That is, the air outlet mode is individually determined for each air-conditioning zone 1c, 1d on the Rr side according to FIG. FIG. 10 is a control map for determining the outlet mode stored in the ROM in advance. In this example, as TAORrDr (corresponding to TAO in FIG. 10) increases, the airflow in the air-conditioning zone 1c on the RrDr side is increased. The exit mode is automatically and sequentially switched from the face (FACE) mode to the bi-level (B / L) mode to the foot (FOOT) mode. Further, as TAORrPa (corresponding to TAO in FIG. 10) rises, the air outlet mode of the air-conditioning zone 1d on the RrPa side is changed from the face (FACE) mode to the bi-level (B / L) mode to the foot (FOOT) mode. It is designed to automatically switch sequentially.

  Here, the face mode is a mode in which conditioned air is blown out only from the face outlet, and the foot mode is a mode in which conditioned air is blown out only from the foot outlet. The bi-level mode is a mode in which conditioned air is blown out from the face air outlet and the foot air outlet.

  For example, in the face mode, the face air outlets 2c and 20c (2d and 20d) are opened at the air outlet switching door 66a (66b), and the conditioned air flows from the face air outlets 2c and 20c (2d and 20d) only in the vehicle interior. Blow out to the upper body side of the Rr occupant. In the bi-level mode, the face outlets 2c, 20c (2d, 20d) and the foot outlet (not shown) are opened at the outlet switching door 66a (66b), and the conditioned air is supplied to the face outlets 2c, 20c (2d). , 20d) and the foot outlets simultaneously blow out to the upper body side and lower body side of the Rr-side occupant in the passenger compartment. In the foot mode, the foot outlet is fully opened at the outlet switching door (not shown), and the conditioned air is mainly blown out from the foot outlet toward the passenger's lower body side.

  As described above, when the air outlet zone is determined for each air conditioning zone, each servo motor of each air outlet switching door is controlled for each air conditioning zone so that the air outlet mode determined for each air conditioning zone is set. Open and close the air outlet switching doors.

  Next, in step S126, the blower voltage to be applied to the blower motor 62a is determined based on the average value of the target outlet temperatures TAORrDr and TAORrPa (= (TAORrDr + TAORrPa) / 2, hereinafter referred to as Rr target average value). The blower voltage is for controlling the air volume of the blower 62, and is determined according to the control map of FIG. 11 stored in advance in the ROM based on the average values of TAORrDr and TAORrPa.

  In the control map of FIG. 11, when the target average value for Rr (= TAO) is in the intermediate region, the blower voltage (that is, the air volume of the blower 62) is a constant value, and when TAO is larger than the intermediate region, this TAO is As the value increases, the blower voltage (that is, the air volume of the blower 62) increases. Further, when TAO is smaller than the intermediate region, the blower voltage (that is, the air volume of the blower 62) decreases as TAO decreases. In this way, the blower voltage is determined.

  Next, in step S127, the target opening degrees θ3 and θ4 of the air mix doors 65a and 65b are calculated by the following formulas 7 and 8.

θ3 = {(TAORrDr−TeRr) / (Tw−TeRr)} × 100 (%)
... (Formula 7)
θ4 = {(TAORrPa−TeRr) / (Tw−TeRr)} × 100 (%)
(Equation 8)
In Equations 7 and 8, TeRr is an evaporator outlet temperature signal of the evaporator temperature sensor 87, and Tw is a cooling water (hot water) temperature signal of the cooling water temperature sensor 82. θ3 = 0% and θ4 = 0% are maximum cooling positions, and in the RrDr side passage 60c and the RrPa side passage 60d, the entire amount of air (cool air) after passing through the evaporator 63 on the Rr side flows through the bypass passages 61a and 61b. . Further, θ3 = 100% and θ4 = 100% are maximum heating positions. In the RrDr side passage 60c and the RrPa side passage 60d, the entire amount of air (cold air) after passing through the evaporator 63 on the Rr side flows into the core heater 64. Heated.

  The control signals indicating the target openings θ3, θ4, the outlet mode, and the blower voltage determined as described above are output to the servo motors 650a, 650b, 660a, 660b, the blower motor 62a, etc., and the air mix door The operations of 65a and 65b, the outlet switching doors 66a and 66b, and the blower 62 are controlled (step S128).

  Thereafter, when a certain period of time elapses in step S129, the process returns to step S121, and the above-described air conditioning control process (steps S121 to S129) is repeated. By repeating such calculation and processing, the air conditioning of the air conditioning zones 1c and 1d on the Rr side is automatically controlled.

  In the following, the inside / outside air mode control (Fr side) performed in accordance with the main routine of FIG. 8 based on the calculated target blowing temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa in the air conditioning zones 1a to 1d as described above. Only), control of the air-conditioning state by air outlet mode control, blower voltage control, and air mix door opening control is called basic air-conditioning control.

  Next, calculation processing of the correction values f10, f2, f11, and f7 in Equation 1, Equation 2, Equation 5, and Equation 6 will be described based on the calculation routine of FIG. The calculation routine of FIG. 12 is performed in common in step S123 of the main routine for all the air conditioning zones 1a to 1d.

  First, in step S200, first air conditioning correction values f1 and f5 are calculated. Specifically, the first air conditioning correction value f1 corresponds to the temperature difference between the Dr side side window and the Pa side side window (TSWDr−TSWPa) in the left-right direction as a detected portion in two different directions. It is calculated based on the map shown in the block of S200. Similarly, the first air conditioning correction value f5 is in the map shown in the block of S200 in FIG. 12 with respect to the temperature difference (TSWPa−TSWDr) between the Pa-side side window and the Dr-side side window in the left-right direction. Calculated based on

  Here, the Dr-side side window temperature TSWDr and the Pa-side side window temperature TSWPa are calculated by Equations 9 and 10, respectively.

TSWDr = MIN (A1, A2, C1, C2) (Formula 9)
TSWPa = MIN (B1, B2, D1, D2) (Equation 10)
In Equations 9 and 10, MIN is an operator that selects the minimum value in the parentheses. That is, each side window temperature TSWDr, TSWPa is the same even when the occupant's face or hand, which is higher than the window temperature, enters the detection range among the plurality of portions of the Dr and Pa side windows. By eliminating the influence of the high temperature part, an accurate window temperature can be extracted.

  The first air conditioning correction values f1 and f5 are negative values that increase in magnitude as the side window temperatures TSWDr and TSWPa on the Dr and Pa sides rise due to the effects of solar radiation from the Dr and Pa sides, respectively. Is calculated as

  Next, correction values f3 and f6 are calculated in step S210, and second air conditioning correction values f2 and f7 are calculated in step S220. Specifically, the correction values f3 and f6 are positive values that increase in magnitude as the Dr-side and Pa-side side window temperatures TSWDr and TSWPa decrease based on the map shown in the block of S210. Is calculated as the value of.

  Further, in step S220, the correction values f3 and f6 are corrected to f2 = f3 × f4 and f7 = f6 × f4 by a proportional coefficient f4 that increases as the vehicle speed Vh detected by the vehicle speed sensor 88 increases. Thus, the second air conditioning correction values f2 and f7 are calculated. That is, the second air conditioning correction values f2 and f7 are correction values reflecting the cold radiation and the effects of the solar radiation on the Dr side and Pa side.

  In the next step S230, third air conditioning correction values f8 and f9 are calculated. Specifically, first, the temperature TSWDr (according to Equation 9) and TSWPa (according to Equation 10) of the Dr-side and Pa-side side windows, where the temperature is likely to rise due to solar radiation (the temperature rise is large), Temperature differences (TSWDr−A5) and (TSWPa−B5) from the temperatures A5 and B5 of the abdomen of the FrDr and FrPa occupants that are not easily affected, that is, the temperature rise due to solar radiation is small. The third air conditioning correction values f8 and f9 are calculated as negative values that increase in size as the temperature differences (TSWDr−A5) and (TSWPa−B5) increase, respectively.

  The third air conditioning correction values f8 and f9 are set according to the window temperature based on the temperature of the part where the temperature rise due to solar radiation is small. That is, even if the window glass on either the left or right side (Dr side or Pa side) is opened and a large amount of outside air enters the passenger compartment and the air conditioning correction on that side is disturbed, on the side where the window glass is not opened The influence of cold radiation and solar radiation can be detected relatively stably by the window temperature and the temperature of the abdomen of the passenger. Therefore, the third air conditioning correction values f8 and f9 can be air conditioning correction values that take into account the effects of cold radiation and solar radiation on the side where the window glass is not opened.

  Note that the processing in step S230 can be independently calculated not only on the Fr side but also on the Rr side as described above. In this case, the third air conditioning correction values f8 and f9 are calculated based on the map described above using the abdomen temperatures C5 and D5 of the RrDr occupant and RrPa occupant instead of A5 and B5, respectively.

  In the next step S240, it is determined whether or not the outside air temperature Tam is an intermediate temperature range (for example, 10 ° C. to 30 ° C.). When the outside air temperature Tam is an intermediate temperature range as a parameter representing the environment outside the vehicle, there is a relatively high possibility that the occupant has opened the window glass. Conversely, on the low temperature side (for example, 10 ° C. or lower) or the high temperature side (for example, 30 ° C. or higher) where the outside air temperature Tam is outside the intermediate temperature range, the window glass can be opened to bring the vehicle interior into a heating state or a cooling state. Sex is very low. Thus, step S240 for determining whether or not the outside air temperature Tam as the environment outside the vehicle is in the intermediate temperature range corresponds to the window glass closed state determining means.

  When the determination result of step S240 is NO, it is determined that the outside air temperature Tam is a temperature in a low temperature region or a high temperature region, and all the window glasses are closed, and the process proceeds to step S250. In step S250, the first air conditioning correction values f1 and f5 calculated in S200 are used as the air conditioning correction values f10 and f11 on the cooling side.

  If the determination result in S240 is YES, it is determined that the outside air temperature Tam is an intermediate temperature range, and the window glass is not fully closed, that is, at least one side window is open. The process proceeds to S260. In step S260, the third air conditioning correction values f8 and f9 calculated in S230 are used as the air conditioning correction values f10 and f11 on the cooling side.

  In addition to the outside air temperature Tam as described above, the window glass closed state determination means detects, for example, whether or not it is in a rain state using a rain sensor. If it is a rain state, the window glass is determined to be in a fully closed state. May be.

  Then, in step S270, based on Formula 1, Formula 2, Formula 5, and Formula 6, FrDr side, FrPa side target blowing temperature TAOFrDr, TAOFrPa, and RrDr side, RrPa side target blowing temperature TAORrDr, TAORrPa are Calculated.

  Since the first embodiment is configured as described above, the following effects can be obtained.

  In a vehicle, the occupant feels the hottest when low-elevation solar radiation hits the occupant's face. On the other hand, when the window, particularly the side window, is radiated at a low elevation angle, the sunshine hits substantially at right angles to the glass surface, and the window temperature rises, which is correlated with the sensation of the passenger.

  In the first embodiment, the solar radiation direction and the intensity of solar radiation can be grasped from the difference between the left and right side window temperatures detected by the temperature detection means, and the first air conditioning correction value calculated based on the solar radiation direction and the intensity of the solar radiation in each air conditioning zone. The target blowing temperature corresponding to the air conditioning load is corrected. Therefore, it is possible to perform air-conditioning control that mitigates the influence of solar radiation in accordance with the occupant's warm feeling without using a solar radiation sensor.

  Note that the non-contact temperature sensor detects a plurality of portions of the side window, selects the lowest temperature among the plurality of detection temperatures, and uses this as the side window temperature. Even if the face or hand of an occupant with a high temperature enters, this can be eliminated and the side window temperature can be detected accurately. Therefore, the contribution degree to the air conditioning of a part with a high detected temperature can be lowered.

  In addition, since the second air conditioning correction value for increasing the heating is calculated according to the temperature of the side window in the vicinity of the occupant representing the degree of the influence of the cold radiation to the occupant, the air conditioning control that matches the sensation of the occupant Is possible. Furthermore, the second air conditioning correction value is decreased as the side window temperature increases, that is, the degree of strengthening heating is reduced when the influence of solar radiation increases, so When the knee cold is alleviated, it is possible to prevent the hot flash of the face due to overcorrection of heating.

  Further, as a parameter representing the environment outside the vehicle, it is determined whether or not the window glass is in a fully closed state depending on whether or not the outside air temperature is in an intermediate temperature range. Air conditioning correction that takes into account the effects of solar radiation based on the side window temperature difference, and if it is determined that any of the window glass is open, it is less susceptible to the temperature and solar radiation of parts that are susceptible to solar radiation Since the third air conditioning correction value is calculated according to the difference from the temperature of the part, the air conditioning correction for the solar radiation and the cold radiation can be accurately performed on the side where the window glass is not opened by the third air conditioning correction value.

  In addition, the airflow resistance of the window side is reduced by reducing the airflow resistance of the side face air outlet on the window side (that is, the opening area is larger) than the airflow resistance of the center face air outlet on the vehicle center side among the face air outlets for passengers in each air conditioning zone. Therefore, it is possible to always perform sufficient air-conditioning correction on the window side against overwhelming cold due to cold radiation and heat due to partial solar radiation, and to suppress overcorrection on the vehicle center side. .

Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is simplified or omitted. 1) -D. 1) will be described.

  The air outlet arrangement state of the indoor air conditioning unit of the vehicle air conditioner in the second embodiment is shown in FIG. 1 as in the first embodiment, and the overall configuration diagram including the indoor air conditioning unit and the control block is shown in FIG. Similar to the embodiment, it is shown in FIG. Description of these FIG. 1 and FIG. 2 is omitted.

  A. 1) FIG. 13 is a schematic configuration diagram of the center on the Fr side or the Rr side, the side face outlet, and the duct in the second embodiment. The opening positions of the center face outlets 20a, 20b and 20c, 20d on the Fr side and the Rr side and the side face outlets 2a, 2b, 2c, 2d on the Fr side and the Rr side are the same as those in the first embodiment. It is.

  That is, also in the second embodiment, the Fr side center face air outlets 20a and 20b are arranged near the center of the instrument panel 91Fr in the left-right direction, and the Fr side side face air outlets 2a and 2b are arranged on the instrument panel 91Fr. It is arrange | positioned in the left-right direction both ends vicinity. Further, the center face air outlets 20c and 20d on the Rr side are arranged near the center of the rear tray 91Rr in the left-right direction, and the side face air outlets 2c and 2d on the Rr side are the ceilings on the doors near the left and right windows on the rear seat ( It is provided on the roof side and blows mainly to the upper body of the window side of the Rr side occupant.

  However, in the second embodiment, as shown in FIG. 13, the center side face outlets 20a, 20b, 20c are provided in any of the air-conditioning zones 1a, 1b, 1c, 1d of FrDr, FrPa and RrDr, RrPa. 20d and the side face outlets 2a, 2b, 2c, and 2d have approximately the same opening area (ventilation resistance), and both are arranged at the branching portions of the side face outlet and the center face outlet. Air distribution doors 68a, 68b, 68c, and 68d for adjusting the air ratio are provided. The opening degree of the air distribution doors 68a, 68b, 68c, 68d is adjusted by each actuator (not shown) controlled by the air conditioner ECU 8.

  B. 1) The non-contact temperature sensors 7Fr and 7Rr for Fr and Rr have the structure shown in FIG. 4 as in the first embodiment, and are arranged at the position of the vehicle interior ceiling shown in FIG. Depending on the arrangement of the sensor elements, infrared rays from the front window 90Fr to both side windows 100a and 100b on the Fr side and from both side windows 100c and 100d on the Rr side to the rear window 90Rr can be collected. .

  In the second embodiment, the detected portions of the non-contact temperature sensors 7Fr and 7Rr are exemplified as matrix detection ranges on the Dr side in FIGS. 14A and 14B, respectively, and the vehicle in FIG. It is set as indicated by the positional relationship seen from above.

  In the first embodiment, the temperatures A1, A2, B1, B2, C1, C2, D1, and D2 of each of the four side windows are detected. However, in the second embodiment, the temperatures under the side windows are detected. The point which detects the temperature of interior part 101a, 101b, 101c, 101d differs.

  That is, in the second embodiment, the Fr non-contact temperature sensor 7Fr includes two surface temperatures A3 and A4 in the front-rear direction of the interior portion 101a below the side window 100a on the FrDr side, and the temperature A5 of the abdomen of the FrDr occupant. As the detected part on the FrDr side, and two surface temperatures B3 and B4 in the front-rear direction of the interior part 101b below the side window 100b on the left and right sides of the vehicle in the left-right symmetrical position, and the temperature of the abdomen of the FrPa occupant B5 is set and arranged as a detected part on the FrPa side.

  Similarly, the Rr non-contact temperature sensor 7Rr has two surface temperatures C3 and C4 in the vertical direction of the interior portion 101c below the side window 100c on the RrDr side, and the temperature C5 of the abdomen of the RrDr occupant on the RrDr side. As the detection part, and the surface temperature D3, D4 in two vertical directions of the interior part 101d below the side window 100d on the RrPa side at the left-right symmetrical position of the vehicle, and the temperature D5 of the abdomen of the RrPa occupant are measured on the RrPa side. Each of the detected parts is set and arranged.

  By providing two temperature detection parts for the interior parts 101a to 101d under each side window, the reliability of the detection value is improved even when the face or hand of a passenger with high temperature enters the detection range of each sensor cell. ing.

  C. 1) The operation in the second embodiment basically follows the main routine shown in FIG. 8 by the air conditioner ECU 8 as the basic air conditioning control, in accordance with the control maps of FIGS. A seat air conditioning process and a rear seat air conditioning process are performed. Similarly to the first embodiment, the target blowout temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa in the air-conditioning zones 1a to 1d, which are basic expressions of the air-conditioning control, are expressed by Expression 1, Expression 2, Expression 5, and Expression 6, respectively. The target opening degrees θ1, θ2, θ3, and θ4 of each air mix door are calculated by Equation 3, Equation 4, Equation 7, and Equation 8, respectively.

  However, the second embodiment is different from the first embodiment in that the interior portions 101a to 101d under the side windows are differently detected parts in two directions, and accordingly, the target shown in FIG. The calculation routine of the blowing temperature is partly different from the calculation routine of FIG. 12 in the first embodiment. In the following, steps that perform the same processing as in the first embodiment will be denoted by the same reference numerals, description thereof will be omitted, and different processing contents will be described.

  In step S201, first air conditioning correction values f1a and f5a are calculated. Specifically, the first air-conditioning correction value f1a is the detected part in two different directions, and the interior parts 101a, 101c under the Dr side side window and the interior parts 101c, 101d under the Pa side window are in the left-right direction. Is calculated based on the map shown in the block of S201 in FIG. 16 for the temperature difference (TUSWDr−TUSWPa). Similarly, the first air conditioning correction value f5a is the temperature of the interior parts 101c, 101d under the Pa-side side window and the interior parts 101a, 101c under the Dr-side side window, which are left and right, as the detected parts in two different directions. It calculates based on the map shown in the block of S201 of FIG. 16 with respect to a difference (TUSWPa-TUSWDr).

  Here, the interior temperature TUSWDr under the Dr side window and the interior temperature TUSWPa under the Pa side window are calculated by Equations 11 and 12, respectively.

TUSWDr = MIN (A3, A4, C3, C4) (Formula 11)
TUSWPa = MIN (B3, B4, D3, D4) (Formula 12)
In Equations 11 and 12, MIN is an operator that selects the minimum numerical value in parentheses. That is, the interior temperature TUSWDr, TUSWPa under each side window is the detection range of the face and hand of the occupant whose temperature is higher than the window temperature among a plurality of portions of the Dr side and Pa side side interior parts. Even in the case of entering, it is possible to extract an accurate interior portion temperature by eliminating the influence of these high temperature portions.

  These first air conditioning correction values f1a and f5a increase in magnitude as the interior temperature TUSWDr and TUSWPa under the side windows of the Dr and Pa sides rise due to the effects of solar radiation from the Dr and Pa sides, respectively. Is calculated as a negative value.

  Next, correction values f3a and f6a are calculated in step S211, and second air conditioning correction values f2 and f7 are calculated in step S221. Specifically, the correction values f3a and f6a are respectively increased in magnitude as the interior temperature TUSWDr and TUSWPa under the side windows on the Dr side and Pa side decrease based on the map shown in the block of S211. Is calculated as a positive value that increases.

  In step S221, the correction values f3a and f6a are corrected to f2 = f3a × f4 and f7 = f6a × f4 by a proportional coefficient f4 that increases as the vehicle speed Vh detected by the vehicle speed sensor 88 increases. Thus, the second air conditioning correction values f2 and f7 are calculated. That is, the second air conditioning correction values f2 and f7 are correction values reflecting the cold radiation and the effects of the solar radiation on the Dr side and Pa side.

  In the next step S231, third air conditioning correction values f8a and f9a are calculated. Specifically, first, the interior temperature TUSWDr (according to Equation 11) and TUSWPa (according to Equation 12) under the side windows of the Dr side and Pa side, which are sites where the temperature is likely to rise due to solar radiation (large temperature rise). The temperature differences (TUSWDr−A5) and (TUSWPa−B5) from the temperatures A5 and B5 of the abdomen of the FrDr and FrPa occupants that are not easily affected by solar radiation, that is, the temperature rise due to solar radiation is small are calculated. The third air conditioning correction values f8a and f9a are calculated as negative values that increase in size as the temperature differences (TUSWDr−A5) and (TUSWPa−B5) increase, respectively.

  The third air conditioning correction values f8a and f9a are set according to the interior temperature under the side window with reference to the temperature of the part where the temperature rise due to solar radiation is small. That is, even if the window glass on either the left or right side (Dr side or Pa side) is opened and a large amount of outside air enters the passenger compartment and the air conditioning correction on that side is disturbed, on the side where the window glass is not opened The influence of cold radiation and solar radiation can be detected relatively stably by the temperature of the interior part under the side window and the temperature of the abdomen of the passenger. Therefore, the third air conditioning correction values f8a and f9a can be air conditioning correction values that take into account the effects of cold radiation and solar radiation on the side where the window glass is not opened.

  In addition, this step S231 process can be independently calculated not only on the Fr side but also on the Rr side as described above. In this case, the third air conditioning correction values f8a and f9a are calculated based on the above-described map using the abdomen temperatures C5 and D5 of the RrDr occupant and RrPa occupant instead of A5 and B5, respectively.

  The next step S240 is the same processing step as the window glass closed state determination means as in the first embodiment, and a description thereof will be omitted.

  When the determination result of step S240 is NO, it is determined that the outside air temperature Tam is a low temperature region or a high temperature region, and all the window glasses are closed, and the process proceeds to step S251. In step S251, the first air conditioning correction values f1a and f5a calculated in S201 are used as the air conditioning correction values f10 and f11 on the cooling side.

  If the determination result in S240 is YES, it is determined that the outside air temperature Tam is an intermediate temperature range, and the window glass is not fully closed, that is, at least one side window is open. The process proceeds to S261. In step S261, the third air conditioning correction values f8a and f9a calculated in S231 are used as the air conditioning correction values f10 and f11 on the cooling side.

  Then, in the same manner as in the first embodiment, in step S270, based on Formula 1, Formula 2, Formula 5, and Formula 6, the target blowing temperatures TAOFrDr, TAOFrPa, RrDr side, and RrPa side on the FrDr side and FrPa side are calculated. Target blowing temperatures TAORrDr and TAORrPa are calculated.

  D. 1) In the second embodiment, as described above, as in the first embodiment, in each air conditioning zone, basic air conditioning control (only on the Fr side) inside / outside air mode control, outlet mode control, In addition to performing blower voltage control and air mix door opening control), the center side face outlets 20a to 20d and the side face based on the calculated air conditioning correction values not performed in the first embodiment. Calculation of the blowing ratio with the outlets 2a to 2d (FIG. 16, S270) and air distribution door control (FIG. 8, S128) according to the calculated ratio are performed.

  That is, in step S270, the Dr-side and Pa-side cooling-side air conditioning correction values f10 and f11 and the Dr-side and Pa-side second air-conditioning correction values f2 and f5, which are correction terms for the target blowing temperature, are shown in FIG. As shown to (a)-(d), the ratio (blowing ratio) of the side face blowing air volume and center face blowing air volume in each air-conditioning zone 1a-1d is calculated.

  That is, in the FrDr-side air conditioning zone 1a, when the air volume determined by the FrDr-side air outlet switching door 56a controlled by the basic air-conditioning process is 100%, the air volume blown from the FrDr-side side face air outlet 2a. As the ratio, as shown in FIG. 17 (a), the correction value MAX (| f10 |) is selected by selecting the correction value having the larger magnitude (absolute value) of the cooling side air conditioning correction value f10 and the second air conditioning correction value f2. , | F2 |) is increased, the blowing rate is increased from 10% to 90%. At this time, the amount of air blown from the center face outlet 20a on the FrDr side decreases from 90% to 10%.

  Since the second air conditioning correction value f2 is a correction value that contributes to strengthening the heating, the FrDr side air distribution control map shown in FIG. 17 (a) is influenced by the effects of solar radiation and cold radiation from the Dr side. That is, when the air conditioning correction is performed to increase the air conditioning capacity of the cooling or heating by each air conditioning correction value, the blown air volume of the FrDr side face outlet 2a which is the window side outlet is also the blown air volume of the FrDr side center face outlet 20a. This further increases the air-conditioning capacity on the FrDr side window side.

  Similarly, in the FrPa-side air conditioning zone 1b, when the air volume determined by the FrPa-side outlet switching door 56b controlled by the basic air-conditioning process is 100%, the outlet from the FrPa-side side face outlet 2b As the air flow rate ratio, as shown in FIG. 17B, a correction value having a larger magnitude (absolute value) of the cooling side air conditioning correction value f11 and the second air conditioning correction value f7 is selected, and this correction value MAX (| f11 As the magnitude of |, | f7 |) increases, the blowing rate is increased from 10% to 90%. At this time, the amount of air blown from the center face outlet 20b on the FrPa side decreases from 90% to 10%.

  Since the second air conditioning correction value f7 is a correction value that contributes to strengthening heating, the FrPa-side air distribution control map shown in FIG. 17B is affected by the effects of solar radiation and cold radiation from the Pa side. That is, when the air-conditioning correction is performed so as to increase the air-conditioning capacity of cooling or heating by each air-conditioning correction value, the blow-off air amount at the FrPa-side side face air outlet 2b which is the window-side air outlet is also the blow-off air amount at the FrPa-side center face air outlet 20b. By further increasing, the air conditioning capacity on the FrPa side window side is further increased.

  Similarly to the Fr side, on the RrDr side air conditioning zone 1c, when the air volume determined by the RrDr side air outlet switching door 66a controlled by the basic air conditioning process is 100%, the Rr side is the top of the RrDr side door. As shown in FIG. 17 (c), the air flow rate ratio from the side face air outlet 2c provided on the ceiling of the air outlet increases as the correction values MAX (| f10 |, | f2 |) increase. Increase the percentage from 10% to 90%. At this time, the amount of air blown from the center face air outlet 20c on the RrDr side decreases from 90% to 10%. Thereby, like the FrDr side, it is possible to further increase the air conditioning capability of the window side on the RrDr side according to the influence of solar radiation and cold radiation from the Dr side.

  Further, in the RrPa-side air conditioning zone 1d, when the air volume determined by the RrPa-side air outlet switching door 66b controlled by the basic air-conditioning process is 100%, the airflow is provided on the ceiling above the RrPa-side door. As shown in FIG. 17 (d), the ratio of the amount of air blown from the side face outlet 2d increases from 10% to 90% as the correction values MAX (| f11 |, | f7 |) increase. increase. At this time, the amount of air blown from the center face outlet 20d on the RrPa side decreases from 90% to 10%. Thereby, the air-conditioning capability of the window side on the RrPa side can be further increased according to the influence of solar radiation and cold radiation from the Pa side, similarly to the FrPa side.

  Based on the blowing ratios thus determined, the opening degree of each of the air distribution doors 68a, 68b, 68c, 68d is controlled by each actuator (not shown) in step S128 in FIG.

  Since the second embodiment is configured as described above, the following effects can be obtained.

  In a vehicle, the occupant feels the hottest when low-elevation solar radiation hits the occupant's face. On the other hand, during low elevation solar radiation, the temperature of the interior part under the side window also rises in the same manner as the side window temperature, and thus has a correlation with the sensation of the passenger.

  In the second embodiment, the solar radiation direction and the intensity of solar radiation can be grasped from the temperature difference between the interior parts under the left and right side windows detected by the temperature detecting means, and the first air conditioning correction value calculated based on this can be obtained. The target blowing temperature corresponding to the air conditioning load in each air conditioning zone is corrected. Therefore, it is possible to perform air-conditioning control that mitigates the influence of solar radiation in accordance with the occupant's warm feeling without using a solar radiation sensor.

  Note that the non-contact temperature sensor detects a plurality of parts of the interior part under the side window, and selects the lowest temperature among the detected temperatures as the interior part temperature under the side window. Even if the face or hand of an occupant with a high temperature enters the detection range of the cell of the temperature sensor, this can be eliminated and the interior temperature under the side window can be accurately detected. Therefore, the contribution degree to the air conditioning of a part with a high detected temperature can be lowered.

  In addition, the second air conditioning correction value for increasing the heating according to the interior temperature under the side window near the occupant representing the degree of the influence of the cold radiation on the occupant is calculated. Air conditioning control becomes possible. Further, the second air conditioning correction value is decreased in accordance with the rise in the interior temperature under the side window, that is, the degree of strengthening heating is reduced when the influence of solar radiation increases, so the influence of solar radiation is large and the cold radiation is large. When the cold of the shoulders and the cold of the knees are alleviated, it is possible to prevent the hot flash of the face due to overcorrection of the heating.

  Further, as a parameter representing the environment outside the vehicle, it is determined whether or not the window glass is in a fully closed state depending on whether or not the outside air temperature is in an intermediate temperature range. Air conditioning correction that takes into account the effects of solar radiation using the first air conditioning correction value based on the temperature difference inside the interior of the side window, and if it is determined that any window glass is open, it is susceptible to solar radiation. The third air conditioning correction value is calculated according to the difference between the temperature of the interior part under the side window, which is a part, and the temperature of the abdomen of the occupant, which is a part that is not easily affected by solar radiation. Air conditioning correction for solar radiation and cold radiation can be performed with high precision on the side where the glass is not opened.

  Furthermore, as the air-conditioning correction value for correcting the air-conditioning to reduce the influence of solar radiation and cold radiation increases (that is, the influence of solar radiation and cold radiation increases), the face to the passengers of each air-conditioning zone Air distribution control is performed to increase the amount of air blown from the side face air outlet on the window side from the amount of air blown from the center face air outlet at the center of the vehicle. Thus, it is possible to always perform sufficient air-conditioning correction on the window side and to suppress overcorrection on the vehicle center side.

(Third embodiment)
Next, a third embodiment of the present invention will be described. The third embodiment is different from the first embodiment in that A.A. 2) The point to be detected in the detection ranges of the non-contact temperature sensors 7Fr and 7Rr for Fr and Rr is different; 2) There is a feature in that the calculation methods of the first and third air conditioning correction values for correcting the target blowing temperature are different due to different detected parts, and the other configuration is the same as that of the first embodiment. Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is simplified or omitted. 2), B. 2) will be described.

  The air outlet arrangement state of the indoor air conditioning unit of the vehicle air conditioner in the third embodiment is shown in FIG. 1 as in the first embodiment, and the overall configuration diagram including the indoor air conditioning unit and the control block is shown in FIG. Similar to the embodiment, it is shown in FIG. Further, the Fr-side or Rr-side center, the side face outlet, and the duct configuration are also shown in FIG. 3 as in the first embodiment. Description of these FIGS. 1 to 3 is omitted.

  A. 2) The non-contact temperature sensors 7Fr and 7Rr for Fr and Rr have the structure shown in FIG. 4 as in the first embodiment, and are arranged at the position of the vehicle interior ceiling shown in FIG. Depending on the arrangement of the sensor elements, infrared rays from the front window 90Fr to both side windows 100a and 100b on the Fr side and from both side windows 100c and 100d on the Rr side to the rear window 90Rr can be collected. .

  In the third embodiment, the detected portions of the non-contact temperature sensors 7Fr and 7Rr are exemplified as matrix detection ranges on the Dr side in FIGS. 18A and 18B, respectively, and the vehicle in FIG. It is set as indicated by the positional relationship seen from above.

  In the first embodiment, the temperatures A1, A2, B1, B2, C1, C2, D1, and D2 of each of the four side windows are detected. In the third embodiment, in addition to them, The difference is that the temperature of the interior portions 101a to 101d under the side window and the temperature of the front window 90Fr are detected.

  That is, in the third embodiment, the Fr non-contact temperature sensor 7Fr includes two surface temperatures A1 and A2 in the vertical direction of the side window 100a on the FrDr side and the interior portion 101a below the side window 100a on the FrDr side. The surface temperature A3, the temperature A5 of the FrDr occupant's abdomen, and the surface temperature A8 of the front window 90Fr are used as detected portions on the FrDr side, and in the vertical direction of the side window 100b on the FrPa side that is in the left-right symmetrical position of the vehicle. Two surface temperatures B1 and B2, a surface temperature B3 of the interior portion 101b under the side window 100b on the FrPa side, an abdomen temperature B5 of the FrPa occupant, and a surface temperature B8 of the front window 90Fr are detected on the FrPa side. Each part is set and arranged.

  Similarly, the Rr non-contact temperature sensor 7Rr includes two surface temperatures C1 and C2 in the vertical direction of the side window 100c on the RrDr side, a surface temperature C4 on the interior portion 101c below the side window 100c on the RrDr side, and RrDr. The temperature C6 of the occupant's abdomen is used as a detected part on the RrDr side, and two surface temperatures D1 and D2 in the vertical direction of the side window 100d on the RrPa side at the left-right symmetrical position of the vehicle, and the side window on the RrPa side The surface temperature D4 of the interior part 101d below 100d and the temperature D6 of the abdomen of the RrPa occupant are set and arranged as the detected part on the RrPa side, respectively.

  By providing two temperature detection portions for each side window, the reliability of the detection value is improved even when the face or hand of an occupant having a high temperature enters the detection range of each sensor cell.

  B. 2) The operation in the third embodiment basically follows the main routine shown in FIG. 8 by the air conditioner ECU 8 as the basic air conditioning control in accordance with the control maps of FIGS. 9 to 11 as in the first embodiment. Front seat air conditioning processing and rear seat air conditioning processing are performed. Similarly to the first embodiment, the target blowout temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa in the air-conditioning zones 1a to 1d, which are basic expressions of the air-conditioning control, are expressed by Expression 1, Expression 2, Expression 5, and Expression 6, respectively. The target opening degrees θ1, θ2, θ3, and θ4 of each air mix door are calculated by Equation 3, Equation 4, Equation 7, and Equation 8, respectively.

  However, the third embodiment is different from the first embodiment in that the side windows 100a to 100d and the front window 90Fr are detected in two different directions, and the target shown in FIG. The calculation routine of the blowing temperature is partly different from the calculation routine of FIG. 12 in the first embodiment. In the following, steps that perform the same processing as in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different processing contents will be described.

  In step S202, first air conditioning correction values f1b and f5b are calculated. Specifically, the first air conditioning correction value f1b corresponds to a temperature difference (TSWDr−TFrW) between the Dr-side side windows 100a and 100c and the front window 90Fr in one of the left and right directions as different two-direction detected parts. Thus, the calculation is performed based on the map shown in the block of S202 of FIG. Similarly, the first air conditioning correction value f5b is a detected portion in two different directions with respect to a temperature difference (TSWPa−TFrW) between the Pa side side windows 100c and 100d and the front window 90Fr on the other in the left and right direction. It is calculated based on the map shown in the block of S202 in FIG.

  Here, the Dr-side side window temperature TSWDr and the Pa-side side window temperature TSWPa are calculated by the above formulas 9 and 10, respectively, as in the first embodiment. As in the first embodiment, among the plurality of portions of the Dr-side and Pa-side side windows 100a to 100d, even when the face or hand of an occupant having a temperature higher than the window temperature enters the detection range, By eliminating the influence of these high temperature parts, an accurate window temperature can be extracted.

  Further, the front window temperature TFrW is calculated by the following formula 13.

TFrW = MIN (A8, B8) (Formula 13)
These first air-conditioning correction values f1b and f5b correspond to the increase in Dr-side and Pa-side side window temperatures TSWDr and TSWPa based on the front window temperature TFrW due to the influence of solar radiation from the Dr-side and Pa-side, respectively. Calculated as a negative value that increases in magnitude.

  Next, correction values f3 and f6 are calculated in step S210, and second air conditioning correction values f2 and f7 are calculated in step S220. Since these processes are the same as those in the first embodiment, description thereof will be omitted.

  In the next step S231, third air conditioning correction values f8a and f9a are calculated. Specifically, first, the interior temperature TUSWDr (according to the equation 14), TUSWPa (according to the equation 15) under the side window on the Dr side and Pa side, where the temperature is likely to increase due to solar radiation (the temperature increase is large), The temperature differences (TUSWDr−A5) and (TUSWPa−B5) from the temperatures A5 and B5 of the abdomen of the FrDr and FrPa occupants that are not easily affected by solar radiation, that is, the temperature rise due to solar radiation is small are calculated. The third air conditioning correction values f8a and f9a are calculated as negative values that increase in size as the temperature differences (TUSWDr−A5) and (TUSWPa−B5) increase, respectively.

  The interior temperature TUSWDr and TUSWPa under the Dr and Pa side windows in the third embodiment are calculated by the following formulas 14 and 15.

TUSWDr = MIN (A3, C4) (Formula 14)
TUSWPa = MIN (B3, D4) (Formula 15)
The third air conditioning correction values f8a and f9a are parts in the vehicle interior that are far from the window and that are close to the window based on the occupant temperature (A5, B5) that is a part where the temperature rise due to solar radiation is small. It is set according to the temperature of the interior part under the side window, which is a part where the temperature rise due to solar radiation is large. That is, even if the window glass on either the left or right side (Dr side or Pa side) is opened and a large amount of outside air enters the passenger compartment and the air conditioning correction on that side is disturbed, on the side where the window glass is not opened The influence of cold radiation and solar radiation can be detected relatively stably by the temperature of the interior part under the side window and the temperature of the abdomen of the passenger. Therefore, the third air conditioning correction values f8a and f9a can be air conditioning correction values that take into account the effects of cold radiation and solar radiation on the side where the window glass is not opened.

  In addition, this step S231 process can be independently calculated not only on the Fr side but also on the Rr side as described above. In this case, the third air conditioning correction values f8a and f9a are calculated based on the above-described map using the abdomen temperatures C6 and D6 of the RrDr occupant and RrPa occupant instead of A5 and B5, respectively.

  The next step S240 is the same processing step as the window glass closed state determination means as in the first embodiment, and a description thereof will be omitted.

  When the determination result of step S240 is NO, it is determined that the outside air temperature Tam is a temperature in a low temperature region or a high temperature region, and all the window glasses are closed, and the process proceeds to step S252. In step S252, the first air conditioning correction values f1b and f5b calculated in S202 are used as the air conditioning correction values f10 and f11 on the cooling side.

  If the determination result in S240 is YES, it is determined that the outside air temperature Tam is an intermediate temperature range, and the window glass is not fully closed, that is, at least one side window is open. The process proceeds to S261. In step S261, the third air conditioning correction values f8a and f9a calculated in S231 are used as the air conditioning correction values f10 and f11 on the cooling side.

  Then, in the same manner as in the first embodiment, in step S270, based on Formula 1, Formula 2, Formula 5, and Formula 6, the target blowing temperatures TAOFrDr, TAOFrPa, RrDr side, and RrPa side on the FrDr side and FrPa side are calculated. Target blowing temperatures TAORrDr and TAORrPa are calculated.

  Since the third embodiment is configured as described above, the following effects can be obtained.

  In a vehicle, the occupant feels the hottest when low-elevation solar radiation hits the occupant's face. On the other hand, when the window, particularly the side window, is radiated at a low elevation angle, the sunshine hits substantially at right angles to the glass surface, and the window temperature rises, which is correlated with the sensation of the passenger.

  In the third embodiment, the solar radiation direction and the intensity of solar radiation can be grasped from the difference between the left and right side window temperatures detected by the temperature detecting means and the front window temperature, and the first calculated based on this can be obtained. The target blowing temperature corresponding to the air conditioning load in each air conditioning zone is corrected by the air conditioning correction value. Therefore, it is possible to perform air-conditioning control that mitigates the influence of solar radiation in accordance with the occupant's warm feeling without using a solar radiation sensor.

  Note that the non-contact temperature sensor detects a plurality of portions of the side window, selects the lowest temperature among the plurality of detection temperatures, and uses this as the side window temperature. Even if the face or hand of an occupant with a high temperature enters, this can be eliminated and the side window temperature can be detected accurately. Therefore, the contribution degree to the air conditioning of a part with a high detected temperature can be lowered.

  Similarly, for the front window temperature and the interior temperature under the side window, by selecting the minimum value from the temperatures of multiple parts, the effects of high temperature parts such as the occupant's face and hands are eliminated and accurate. The temperature can be detected.

  In addition, since the second air conditioning correction value for increasing the heating is calculated according to the temperature of the side window in the vicinity of the occupant representing the degree of the influence of the cold radiation to the occupant, the air conditioning control that matches the sensation of the occupant Is possible. Furthermore, the second air conditioning correction value is decreased as the side window temperature increases, that is, the degree of strengthening heating is reduced when the influence of solar radiation increases, so When the knee cold is alleviated, it is possible to prevent the hot flash of the face due to overcorrection of heating.

  Further, as a parameter representing the environment outside the vehicle, it is determined whether or not the window glass is in a fully closed state depending on whether or not the outside air temperature is in an intermediate temperature range. Air conditioning correction that takes into account the effects of solar radiation using the air conditioning correction value, and if it is determined that any window glass is open, it is a part that is susceptible to solar radiation, Since the third air conditioning correction value is calculated according to the difference between the temperature of the interior part under a certain side window and the temperature of the occupant's abdomen, which is a part that is not easily affected by solar radiation and is far from the window. With this third air conditioning correction value, it is possible to accurately perform air conditioning correction for solar radiation and cold radiation on the side where the window glass is not opened.

  In addition, the airflow resistance of the window side is reduced by reducing the airflow resistance of the side face air outlet on the window side (that is, the opening area is larger) than the airflow resistance of the center face air outlet on the vehicle center side among the face air outlets for passengers in each air conditioning zone. Therefore, it is possible to always perform sufficient air-conditioning correction on the window side against overwhelming cold due to cold radiation and heat due to partial solar radiation, and to suppress overcorrection on the vehicle center side. .

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described. The fourth embodiment is different from the first embodiment in A.M. 3) The point to be detected in the detection ranges of the non-contact temperature sensors 7Fr and 7Rr for Fr and Rr is different; 3) It is characterized in that the calculation method of the first and second air conditioning correction values for correcting the target blowing temperature is different due to the difference in the detected part and that the third tone correction value is not used, and the other configurations are The same as in the first embodiment. Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is simplified or omitted. 3), B. 3) will be described.

  The air outlet arrangement state of the indoor air conditioning unit of the vehicle air conditioner in the fourth embodiment is shown in FIG. 1 as in the first embodiment, and the overall configuration diagram including the indoor air conditioning unit and the control block is shown in FIG. Similar to the embodiment, it is shown in FIG. Further, the Fr-side or Rr-side center, the side face outlet, and the duct configuration are also shown in FIG. 3 as in the first embodiment. Description of these FIGS. 1 to 3 is omitted.

  A. 3) The non-contact temperature sensors 7Fr and 7Rr for Fr and Rr have the structure shown in FIG. 4 as in the first embodiment, and are arranged at the position of the vehicle interior ceiling shown in FIG. Depending on the arrangement of the sensor elements, infrared rays from the front window 90Fr to both side windows 100a and 100b on the Fr side and from both side windows 100c and 100d on the Rr side to the rear window 90Rr can be collected. .

  In the fourth embodiment, the detected portions of the non-contact temperature sensors 7Fr and 7Rr are exemplified as matrix detection ranges on the Dr side in FIGS. 21A and 21B, respectively, and the vehicle of FIG. It is set as indicated by the positional relationship seen from above.

  In the first embodiment, the temperatures A1, A2, B1, B2, C1, C2, D1, and D2 of each of the four side windows are detected. In the fourth embodiment, the left and right windows are detected. Alternatively, the interior temperature below is not detected, but the surface temperatures of the front window 90Fr and the rear window 90Rr are detected.

  That is, in the fourth embodiment, the Fr non-contact temperature sensor 7Fr receives the surface temperature A8 of the front window 90Fr on the FrDr side and the surface temperature B8 of the front window 90Fr on the FrPa side at the left-right symmetrical position of the vehicle. It is set and arranged as a detection unit.

  Similarly, the non-contact temperature sensor 7Rr for Rr is set and detected using the surface temperature C9 of the rear window 90Rr on the RrDr side and the surface temperature D9 of the rear window 90Rr on the RrPa side in the left-right symmetric position of the vehicle as detected parts. Has been placed.

  By providing two temperature detection portions for the front window and the rear window, the reliability of the detection value is improved even when the face or hand of an occupant having a high temperature enters the detection range of each sensor cell.

  In addition, although the non-contact temperature sensors 7Fr and 7Rr of the fourth embodiment are arranged on the left and right center ceilings, the present invention is not limited thereto, and the boundary portion between the lowermost part of the front window 90Fr and the instrument panel 91Fr is shown. Arranged at the center of the left and right sides to detect the surface temperature at a plurality of locations on the front window 90Fr, and similarly arranged at the center of the left and right of the boundary between the lowermost part of the rear window 90Rr and the rear tray 91Rr, You may make it detect the surface temperature of this.

  B. 3) The operation in the fourth embodiment basically follows the main routine shown in FIG. 8 by the air conditioner ECU 8 in accordance with the control map of FIGS. A seat air conditioning process and a rear seat air conditioning process are performed.

  However, the target blowing temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa in the air conditioning zones 1a to 1d, which are basic expressions of the air conditioning control, are different from the expressions 1, 2, 5, and 6 in the first embodiment. Is calculated using Note that the target opening degrees θ1, θ2, θ3, and θ4 of the air mix doors are calculated by the above formula 3, formula 4, formula 7, and formula 8, respectively, as in the first embodiment.

  Further, the fourth embodiment differs from the first embodiment in that the detected parts in two different directions are the front window and the rear window. Accordingly, the calculation of the target blowing temperature shown in FIG. 23 is made accordingly. The routine is different from the calculation routine of FIG. 12 in the first embodiment.

  In step S203, first air conditioning correction values f1c and f5c are calculated. Specifically, the first air conditioning correction value f1c is a detected portion in two different directions with respect to a temperature difference (TFrW−TRrW) between the front window 90Fr on one side in the front-rear direction and the rear window 90Rr on the other side. , Based on the map shown in the block of S203 in FIG. Similarly, the first air conditioning correction value f5c corresponds to a temperature difference (TRrW−TFrW) between the rear window 90Rr and the front window 90Fr on the other side in the front-rear direction as a detected portion in two different directions. It is calculated based on the map shown in the block of S203.

  Here, the front window temperature TFrW is calculated by Equation 13 as in the third embodiment. Further, the rear window temperature TRrW is calculated by the following mathematical formula 16.

TRrW = MIN (C9, D9) (Formula 16)
As in the first embodiment, even if the face or hand of an occupant whose temperature is higher than each window temperature is within the detection range among the plurality of parts of the front window and the rear window, the influence of these high-temperature parts. Therefore, accurate front window temperature and rear window temperature can be extracted.

  The first air conditioning correction values f1c and f5c are calculated as negative values that increase in magnitude as the front window temperature TFrW and the rear window temperature TRrW rise due to the influence of solar radiation from the Fr side and the Rr side, respectively. Is done.

  Next, in step S212, correction values f3b and f6b are calculated, and in step S222, second air conditioning correction values f2 and f7 are calculated. Specifically, the correction values f3b and f6b are calculated as positive values that increase in size as the surface temperature TRrW of the rear window 90Rr decreases based on the map shown in the block of S212. The In this example, f3b = f6b.

  In step S222, the correction values f3b and f6b are corrected to f2 = f3b × f4 and f7 = f6b × f4 by a proportional coefficient f4 that increases as the vehicle speed Vh detected by the vehicle speed sensor 88 increases. Thus, the second air conditioning correction values f2 and f7 are calculated. That is, the second air conditioning correction values f2 and f7 are correction values reflecting the effects of solar radiation and cold radiation from the Rr side. In this example, f2 = f7.

  Then, in the next step S271, the target blowout temperatures TAOFrDr and TAOFrPa on the FrDr side and FrPa side, and the target blowout temperatures TAORrDr and TAORrPa on the RrDr side and RrPa side are set to the first air conditioning correction values f1c and f5c and the second air conditioning. Using the correction values f2 and f7, the values are calculated by Expressions 17 to 20, respectively.

TAOFrDr = KsetFr × TsetFrDr−KrFr × TrFr
−KamFr × Tam−CFr + f1c + f2
... (Formula 17)
TAOFrPa = KsetFr × TsetFrPa−KrFr × TrFr
-KamFr × Tam-CFr + f1c + f7
... (Formula 18)
TAORrDr = KsetRr × TsetRrDr−KrRr × TrRr
−KamRr × Tam−CRr + f5c + f2
(Equation 19)
TAORrPa = KsetRr × TsetRrPa−KrRr × TrRr
−KamRr × Tam−CRr + f5c + f7
(Equation 20)
Note that KsetFr, KrFr, KamFr, KsetRr, KrRr, KamRr are the gains of the respective signals, and CFr, CRr are constants.

  Since the fourth embodiment is configured as described above, the following effects can be obtained.

  In a vehicle, the occupant feels the hottest when low-elevation solar radiation hits the occupant's face. On the other hand, the front window and the rear window have a correlation with the occupant's thermal sensation because the window temperature rises during low elevation solar radiation from the Fr side and the Rr side, respectively.

  In the fourth embodiment, the solar radiation direction and the intensity of solar radiation can be grasped from the difference between the one front window temperature in the front-rear direction detected by the temperature detection means and the other rear window temperature, and the calculation is based on this. The target air temperature corresponding to the air conditioning load in each air conditioning zone is corrected by the first air conditioning correction value. Therefore, it is possible to perform air-conditioning control that mitigates the influence of solar radiation in accordance with the occupant's warm feeling without using a solar radiation sensor.

  The non-contact temperature sensor detects a plurality of portions in each of the front and rear windows, and selects the lowest temperature from the plurality of detected temperatures to set it as the front and rear window temperatures. Even if the face or hand of an occupant with a high temperature enters the cell detection range, the temperature of the front and rear windows can be accurately detected. Therefore, the contribution degree to the air conditioning of a part with a high detected temperature can be lowered.

  In addition, since the second air conditioning correction value for increasing the heating is calculated according to the temperature of the rear window near the passenger on the Rr side that best represents the degree of the influence of the cold radiation on the passenger, the influence of the cold radiation is reduced. Air conditioning control that matches the warmth of the Rr side occupant that is most easily received is possible. In addition, the second air conditioning correction value is decreased as the rear window temperature increases, that is, the degree of strengthening heating is reduced when the influence of solar radiation increases. When the knee cold is alleviated, it is possible to prevent the hot flash of the face due to overcorrection of heating.

  In addition, the airflow resistance of the window side is reduced by reducing the airflow resistance of the side face air outlet on the window side (that is, the opening area is larger) than the airflow resistance of the center face air outlet on the vehicle center side among the face air outlets for passengers in each air conditioning zone. Therefore, it is possible to always perform sufficient air-conditioning correction on the window side against overwhelming cold due to cold radiation and heat due to partial solar radiation, and to suppress overcorrection on the vehicle center side. .

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described. The fifth embodiment is different from the first embodiment in that A.A. 4) Points to be detected in the detection ranges of the non-contact temperature sensors 7Fr and 7Rr for Fr and Rr are different; 4) The correction of the delay in the rise of the window temperature due to the change in the solar radiation state, C.I. 4) The calculation method of the 1st thru | or 3rd air-conditioning correction value which correct | amends target blowing temperature differs according to a to-be-detected site | part, and D. 4) A seat air conditioner is provided, which is characterized in that air distribution control is performed on the blowout air volume at a plurality of locations on the seat based on the first and third air conditioning correction values, and the other configurations are the same as those in the first embodiment. is there. Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is simplified or omitted. 4) -D. 4) will be described.

  The air outlet arrangement state of the indoor air conditioning unit of the vehicle air conditioner in the fifth embodiment is shown in FIG. 1 as in the first embodiment, and the overall configuration diagram including the indoor air conditioning unit and the control block is shown in FIG. Similar to the embodiment, it is shown in FIG. Further, the Fr-side or Rr-side center, the side face outlet, and the duct configuration are also shown in FIG. 3 as in the first embodiment. Description of these FIGS. 1 to 3 is omitted.

  A. 4) The non-contact temperature sensors 7Fr and 7Rr for Fr and Rr have the structure shown in FIG. 4 as in the first embodiment, and are arranged at the position of the vehicle interior ceiling shown in FIG. Depending on the arrangement of the sensor elements, infrared rays from the front window 90Fr to both side windows 100a and 100b on the Fr side and from both side windows 100c and 100d on the Rr side to the rear window 90Rr can be collected. .

  In the fifth embodiment, the detected portions of the non-contact temperature sensors 7Fr and 7Rr are exemplified as matrix detection ranges on the Dr side in FIGS. 24A and 24B, respectively, and the vehicle in FIG. It is set as indicated by the positional relationship seen from above.

  In the first embodiment, the temperatures A1, A2, B1, B2, C1, C2, D1, and D2 of each of the four side windows in the left-right direction are detected. In the fifth embodiment, these temperatures are detected. In addition, the temperature of the interior portions 101a to 101d under the side window, the temperature of the front window 90Fr, the temperature of the rear window 90Rr, and the temperature of the rear tray 91Rr are different.

  That is, in the fifth embodiment, the Fr non-contact temperature sensor 7Fr includes two surface temperatures A1 and A2 in the vertical direction of the side window 100a on the FrDr side and the interior portion 101a below the side window 100a on the FrDr side. The surface temperature A3, the temperature A5 of the FrDr occupant's abdomen, the two upper body temperatures A6 and A7 of the FrDr occupant, and the surface temperature A8 of the front window 90Fr are detected on the FrDr side and the vehicle is symmetrical The surface temperatures B1 and B2 in the vertical direction of the side window 100b on the FrPa side at the position, the surface temperature B3 of the interior portion 101b below the side window 100b on the FrPa side, the temperature B5 of the abdomen of the FrPa occupant, and FrPa Two upper body temperatures B6 and B7 of the passenger and the surface temperature B8 of the front window 90Fr Each as the detected portion of rPa side, it is set and arranged.

  Similarly, the Rr non-contact temperature sensor 7Rr includes two surface temperatures C1 and C2 in the vertical direction of the side window 100c on the RrDr side, a surface temperature C4 on the interior portion 101c below the side window 100c on the RrDr side, and RrDr. The temperature C6 of the occupant's abdomen, the two upper body temperatures C7 and C8 of the occupant RrDr, the surface temperature C9 of the rear window 90Rr, and the surface temperature C10 of the rear tray 91Rr are detected on the RrDr side, and Two surface temperatures D1, D2 in the vertical direction of the side window 100d on the RrPa side in the left-right symmetric position, a surface temperature D4 of the interior part 101d under the side window 100d on the RrPa side, D6 of the abdomen of the RrPa occupant, Two upper body temperatures D7 and D8 of the RrPa occupant and the surface temperature D9 of the rear window 90Rr , Respectively and a surface temperature D10 of Riyatore 91Rr as the detected portion of RrPa side, is set and arranged.

  The temperature is within the detection range of each sensor cell by providing a plurality of temperature detection portions for each of the side windows 100a to 100d, the interior portions 101a to 101d under the side windows, the front window 90Fr, the rear window 90Rr, and the rear tray 91Rr. Even when a high occupant's face or hand enters, the reliability of the detected value is improved.

  B. 4) In the fifth embodiment, the side window temperature rise delay due to the change in the solar radiation state, which was not considered in the first embodiment, is corrected. That is, even if the state of solar radiation hitting the glass changes suddenly, the glass temperature cannot follow the change in the solar radiation state and changes slowly.

  FIG. 26 is a flowchart showing the correction processing routine. This processing routine is executed when the detected temperature signal of each detected part is read from the non-contact temperature sensors 7Fr and 7Rr in step S122 in the main routine of FIG. The processing routine of FIG. 26 is executed on each of the Dr side and the Pa side. In FIG. 26, the Dr side is mainly shown, and the Pa side is shown in parentheses.

  First, in step S300, the Dr side (Pa side) side window temperature TSWDr (TSWPa) is substituted for the corrected Dr side (Pa side) side window temperature TSWDr * (TSWPa *) as an initial condition. The Dr-side and Pa-side side window temperatures TSWDr and TSWPa are calculated by the above formulas 9 and 10, as in the first embodiment.

  Next, in step S310, it is determined whether or not the Dr-side (Pa-side) side window temperature TSWDr (TSWPa) is higher than 4 seconds ago. If the determination result is YES, the process proceeds to step S320, and if it is NO, the process proceeds to step S340.

  In step S320, it is determined whether or not the Dr side (Pa side) occupant upper body temperature TPUDr (TPUPa) is higher than 4 seconds ago. If the determination result is YES, the process proceeds to step S330, and if it is NO, the process proceeds to step S340.

  In addition, Dr side and Pa side passenger | crew upper body temperature TPUDr, TPUPa are calculated by Numerical formula 21 and Numerical formula 22, respectively.

TPUDr = MIN (A6, A7) (Formula 21)
TPUPa = MIN (B6, B7) (Formula 22)
In step S330, both the Dr side (Pa side) side window temperature TSWDr (TSWPa) and the Dr side (Pa side) occupant upper body temperature TPUDr (TPUPa) have risen from the previous four seconds. Since the influence of solar radiation from the side) has increased, there is a possibility that a rise delay of the Dr side (Pa side) side window temperature TSWDr (TSWPa) may occur, so this rise delay is corrected by Equation 23 (Equation 24).

TSWDr * (current) = TSWDr * (4 seconds ago) + (ΔTPUDr−ΔTSWDr)
(Equation 23)
TSWPa * (current) = TSWPa * (4 seconds ago) + (ΔTPUPa−ΔTSWPa)
... (Formula 24)
This Equation 23 (Equation 24) is obtained by adding the amount of increase in the Dr side (Pa side) occupant upper body temperature for 4 seconds ΔTPUDr (ΔTPUPa) to the corrected Dr side (Pa side) side window temperature TSWDr * (TSWPa *) 4 seconds ago. Is corrected to be the current correction Dr side (Pa side) side window temperature TSWDr * (TSWPa *) by adding the difference between the increase amount ΔTSWDr (ΔTSWPa) of Dr and the Dr side (Pa side) side window temperature It is. That is, the response of the increase in the side window temperature is improved by correcting the amount that the increase in the side window temperature is slower than the increase in the passenger upper body temperature.

  On the other hand, in step S340, at least one of the Dr side (Pa side) side window temperature TSWDr (TSWPa) and the Dr side (Pa side) occupant upper body temperature TPUDr (TPUPa) has not increased in temperature compared to 4 seconds ago (that is, the temperature When there is no change or the temperature is decreased), the corrected Dr side (Pa side) side window temperature TSWDr * (TSWPa *) after the response is improved to the original value by the calculation according to Formula 25 (Formula 26). It is intended to achieve smooth convergence to the original value while suppressing the discomfort of passengers due to sudden changes.

TSWDr * (current) = TSWDr * (4 seconds ago)
-(TSWDr * (4 seconds ago) -TSWDr (current)) / 30
... (Formula 25)
TSWPa * (current) = TSWPa * (4 seconds ago)
-(TSWPa * (4 seconds ago) -TSWPa (current)) / 30
... (Formula 26)
By repeating the above processing, the Dr side (Pa side) side window temperature is corrected so as to change rapidly on the rising side, and in a constant temperature state after the response is improved or in a temperature lowering state, it returns to a smooth original value. Can be achieved.

  C. 4) The operation in the fifth embodiment is basically the same basic air-conditioning control as in the first embodiment, and the air-conditioner ECU 8 follows the main routine shown in FIG. Front seat air conditioning processing and rear seat air conditioning processing are performed. Similarly to the first embodiment, the target blowout temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa in the air-conditioning zones 1a to 1d, which are basic expressions of the air-conditioning control, are expressed by Expression 1, Expression 2, Expression 5, and Expression 6, respectively. The target opening degrees θ1, θ2, θ3, and θ4 of each air mix door are calculated by Equation 3, Equation 4, Equation 7, and Equation 8, respectively.

  However, the fifth embodiment is different from the first embodiment in that a side window and a rear window are used as detected parts in two different directions, and accordingly, the calculation of the target blowing temperature shown in FIG. 27 is performed. The routine is different from the calculation routine of FIG. 12 in the first embodiment. In the following, steps that perform the same processing as in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different processing contents will be described.

  In the calculation routine shown in FIG. 27, the Dr-side and Pa-side side window temperatures TSWDr and TSWPa are the same as those described in B. In 4), the correction values TSWDr * and TSWPa * described with reference to FIG. 26 are used.

  In step S204, first air conditioning correction values f1d and f5d are calculated. Specifically, the first air conditioning correction value f1d is a graph showing the temperature difference (TSWDr−TRrW) between the Dr-side side window and the rear window 90Rr in one of the left and right directions as different two-direction detected parts. It is calculated based on the map shown in the block of S204 of 27. Similarly, the first air-conditioning correction value f5d corresponds to the temperature difference (TSWPa−TRrW) between the Pa-side side window and the rear window 90Rr on the other in the left-right direction as different two-direction detected parts in FIG. It is calculated based on the map shown in the block of S204.

  Here, the Dr-side side window temperature TSWDr and the Pa-side side window temperature TSWPa are calculated by the above formulas 9 and 10, respectively, as in the first embodiment. Further, the rear window temperature TRrW is calculated by Expression 16 as in the fourth embodiment.

  As in the first embodiment, even when the face or hand of the occupant whose temperature is higher than the window temperature is within the detection range among the plurality of portions of the Dr-side and Pa-side side windows, By eliminating the influence of the above, an accurate window temperature can be extracted.

  These first air conditioning correction values f1d and f5d correspond to the side window temperatures TSWDr and TSWPa on the Dr side and Pa side that rise due to the influence of solar radiation from the Dr side and Pa side, respectively, with the rear window temperature TRrW as a reference. Calculated as a negative value that increases in magnitude.

  Next, correction values f3b and f6b are calculated in step S212, and second air conditioning correction values f2 and f7 are calculated in step S222. Specifically, the correction values f3b and f6b are calculated as positive values that increase in size as the surface temperature TRrW of the rear window 90Rr decreases based on the map shown in the block of S212. The In this example, f3b = f6b.

  In step S222, the correction values f3b and f6b are corrected to f2 = f3b × f4 and f7 = f6b × f4 by a proportional coefficient f4 that increases as the vehicle speed Vh detected by the vehicle speed sensor 88 increases. Thus, the second air conditioning correction values f2 and f7 are calculated. That is, the second air conditioning correction values f2 and f7 are correction values reflecting the effects of solar radiation and cold radiation from the Rr side. In this example, f2 = f7.

  In the next step S232, third air conditioning correction values f8b and f9b are calculated. Specifically, first, FrDr side, FrPa side occupant upper body temperature TPUDr (according to the above equation 21), TUPPa (according to the above equation 22), which are sites where the temperature is likely to increase due to solar radiation (larger temperature rise), Temperature differences (TPUDr−A5) and (TPUPa−B5) are calculated from the temperature A5 and B5 of the abdomen of the FrDr and FrPa occupants below the upper body, which is less affected by solar radiation, that is, the temperature rise due to solar radiation is small. The The third air conditioning correction values f8b and f9b are calculated as negative values that increase in size as the temperature differences (TPUDr−A5) and (TPUPa−B5) increase, respectively.

  The third air conditioning correction values f8b and f9b are set according to the occupant's upper body temperature based on the temperature of the part where the temperature rise due to solar radiation is small. That is, even if the window glass on either the left or right side (Dr side or Pa side) is opened and a large amount of outside air enters the passenger compartment and the air conditioning correction on that side is disturbed, on the side where the window glass is not opened The effects of cold radiation and solar radiation can be detected relatively stably based on the difference between the upper body temperature of the occupant and the temperature of the abdomen. Therefore, the third air conditioning correction values f8d and f9d can be air conditioning correction values that take into account the effects of cold radiation and solar radiation on the side where the window glass is not opened.

  In addition, this step S232 process can be independently calculated not only on the Fr side but also on the Rr side as described above. In this case, the upper body temperature of the RrDr occupant and the RrPa occupant is calculated using C7 and C8 in Equation 21 and D7 and D8 in Equation 22. Further, the third air conditioning correction values f8d and f9d can be calculated based on the above-mentioned map by using the abdominal temperatures C6 and D6 of the RrDr occupant and RrPa occupant instead of A5 and B5, respectively.

  The next step S240 is the same processing step as the window glass closed state determination means as in the first embodiment, and a description thereof will be omitted.

  When the determination result of step S240 is NO, it is determined that the outside air temperature Tam is a low temperature region or a high temperature region, and all the window glasses are closed, and the process proceeds to step S253. In step S253, the first air conditioning correction values f1d and f5d calculated in S204 are used as the air conditioning correction values f10 and f11 on the cooling side.

  If the determination result in S240 is YES, it is determined that the outside air temperature Tam is an intermediate temperature range, and the window glass is not fully closed, that is, at least one side window is open. The process proceeds to S262. In step S262, the third air conditioning correction values f8b and f9b calculated in S232 are used as the air conditioning correction values f10 and f11 on the cooling side.

  Then, in the same manner as in the first embodiment, in step S270, based on Formula 1, Formula 2, Formula 5, and Formula 6, the target blowing temperatures TAOFrDr, TAOFrPa, RrDr side, and RrPa side on the FrDr side and FrPa side are calculated. Target blowing temperatures TAORrDr and TAORrPa are calculated.

  D. 4) The fifth embodiment includes a seat air conditioner that blows air from a plurality of air outlets of the seat skin, in addition to the same indoor air conditioning unit as in the first embodiment. Another feature is that the air outlet control in the seat air conditioning is performed in accordance with the air conditioning correction values.

  FIG. 28 is a diagram illustrating a schematic configuration of a seat air conditioner according to the fifth embodiment. In FIG. 28, an FrDr seat (seat cushion 30a, seat back 31a) and an FrPa seat (seat cushion 30b, seat back 31b) are shown.

  The sheet air conditioner 200 includes a blower unit 201 that blows conditioned air, and an FrDr duct 202a and an FrPa duct 202b that guide the conditioned air from the blower unit 201 to the FrDr sheet and the FrPa sheet, respectively. The FrDr duct 202a is branched into a window side duct 203a and a center side duct 204a, and the FrPa duct 202a is branched into a window side duct 203b and a center side duct 204b.

  Each skin of the FrDr seat cushion 30a, seat back 31a, and FrPa seat cushion 30b, seat back 31b is provided with a number of window side outlets 206a, 206b in a line along the window side, A large number of center side outlets 207a and 207b are provided in a line shape at the center of the left and right of the seat.

  The window side and center side ducts 203a and 204a on the FrDr side are connected to the window side outlet 206a and the center side outlet 207a of the FrDr sheet, respectively, and the conditioned air from the blower unit 201 is supplied to the skin from the outlets 206a and 207a. Blow out. Similarly, each of the ducts 203b and 204b on the FrPa side is connected to the window side outlet 206b and the center side outlet 207b of the FrPa sheet, respectively, and the conditioned air from the blower unit 201 is out of the skin through the outlets 206b and 207b. Blow out.

  An air distribution door 205a that adjusts the ratio of the amount of air blown to both the ducts 203a and 204a is provided at a branch portion between the window side duct 203a and the center side duct 204a of the FrDr duct 202a. Similarly, an air distribution door 205b that adjusts the ratio of the amount of air blown to both the ducts 203b and 204b is provided at a branch portion between the window side duct 203b and the center side duct 204b of the FrPa duct 202b.

  The air distribution doors 205a and 205b are independently controlled in opening degree by the air conditioner ECU8. In addition, control of the ventilation volume from the ventilation unit 201, blowing temperature, etc. is performed by normal seat air-conditioning control by air-conditioner ECU8.

  Next, the operation of the air distribution control of the seat air conditioning in the fifth embodiment will be described. The air conditioner ECU 8 is connected to the C.I. According to the first air conditioning correction values f1d and f5d and the second air conditioning correction values f2 and f7 described in 4), the window-side blowing ratio in each seat, that is, the opening degree of the air distribution doors 205a and 205b is calculated.

  Specifically, for the FrDr seat, the magnitude | f1d | of the first air-conditioning correction value f1d calculated according to the Dr-side side window temperature TSWDr affected by the Dr-side solar radiation, and the rear window 90Rr side The correction value MAX (| f1d |, | f2 |) of the larger one of the magnitude | f2 | of the second air conditioning correction value f2 calculated according to the influence of the solar radiation and the cold radiation from is calculated.

  Similarly, for the FrPa seat, the magnitude | f5d | of the first air-conditioning correction value f5d calculated according to the Pa-side side window temperature TSWPa affected by the Pa-side solar radiation and the rear window 90Rr side The larger correction value MAX (| f1d |, | f7 |) of the magnitude | f7 | of the second air conditioning correction value f7 calculated according to the influence of solar radiation and cold radiation is calculated.

  Then, the correction values MAX (| f1d |, | f2 |), MAX (| f1d |, | f7 |) increase as the correction values MAX (| f1d |, | f2 |) increase according to the characteristics shown in the maps of FIGS. The opening degree of the air distribution doors 205a and 205b is determined so that the blowout air volume ratio on the side increases.

  Note that the blowout ratios α (%) of the window-side air outlets 206a and 206b are airflow ratios when the airflow rates of the FrDr duct 202a and the FrPa duct 202b are set to 100%. Each outlet ratio of the outlets 206a and 206b is 100-α (%).

  When the correction value MAX (| f1d |, | f2 |) becomes large, the influence of the solar radiation on the Dr side increases from the map of each air conditioning correction value shown in FIG. 27 and the Dr side side window temperature TSWDr rises. Or when the rear window temperature TRrW decreases and the influence of cold radiation increases. Therefore, in this case, the window side blowing ratio on the Dr side is increased so that the air conditioning state on the window side of the FrDr occupant who is strongly influenced by solar radiation and cold radiation is adapted to the temperature sensation of the FrDr occupant, and against the uneven solar radiation. However, it is possible to sufficiently correct the seat air conditioning even for cold shoulders and cold knees caused by cold radiation.

  Similarly, when the correction value MAX (| f5d |, | f7 |) increases, the influence of solar radiation on the Pa side increases from the map of each air conditioning correction value shown in FIG. 27, and the Pa-side side window temperature TSWPa increases. When the temperature rises or when the rear window temperature TRrW decreases and the influence of cold radiation increases. Therefore, in this case, the window side blowing ratio on the Pa side is increased, the window air-conditioning state of the FrPa occupant who is strongly affected by solar radiation and cold radiation is adapted to the temperature sensation of the FrPa occupant, However, it is possible to sufficiently correct the seat air conditioning even for cold shoulders and cold knees caused by cold radiation.

  Further, as described above, when the degree of seat air conditioning on the window side is increased, the degree of seat air conditioning on the center side is lowered. Therefore, the seat air conditioning is not overcorrected on the center side.

  Since the fifth embodiment is configured as described above, the following effects can be obtained.

  In a vehicle, the occupant feels the hottest when low-elevation solar radiation hits the occupant's face. On the other hand, when the window, particularly the side window, is radiated at a low elevation angle, the sunshine hits substantially at right angles to the glass surface, and the window temperature rises, which is correlated with the sensation of the passenger.

  In the fifth embodiment, the solar radiation direction and the intensity of solar radiation can be grasped from the difference between the left and right side window temperatures detected by the temperature detecting means and the rear window temperature, and the first calculated based on this can be obtained. The target blowing temperature corresponding to the air conditioning load in each air conditioning zone is corrected by the air conditioning correction value. Therefore, it is possible to perform air-conditioning control that mitigates the influence of solar radiation in accordance with the occupant's warm feeling without using a solar radiation sensor.

  At this time, the window temperature is corrected by the temperature change of the upper body of the occupant, which is a part that is susceptible to solar radiation other than the window. That is, it is possible to correct the temperature of the window, which takes time until the temperature rises and stabilizes after the solar radiation hits, using the temperature change amount of the upper body of the occupant whose temperature rises with good response when the sun hits. Therefore, by using this corrected window temperature, it is possible to perform air conditioning that matches the occupant's feeling of warmth.

  It should be noted that the non-contact temperature sensor detects a plurality of portions in each of the side window and the rear window, selects the lowest temperature from the plurality of detected temperatures, and sets these as the side window temperature and the rear window temperature, respectively. Even if the face or hand of an occupant with a high temperature enters the detection range of the cell of the contact temperature sensor, this can be eliminated and the side window temperature and the rear window temperature can be detected with high accuracy. Therefore, the contribution degree to the air conditioning of a part with a high detected temperature can be lowered.

  In addition, since the second air conditioning correction value for increasing the heating is calculated according to the temperature of the rear window in the vicinity of the Rr-side occupant that best represents the degree of the influence of the cold radiation on the occupant, Combined air conditioning control is possible. In addition, the second air conditioning correction value is decreased as the rear window temperature increases, that is, the degree of strengthening heating is reduced when the influence of solar radiation increases. When the knee cold is alleviated, it is possible to prevent the hot flash of the face due to overcorrection of heating.

  Further, as a parameter representing the environment outside the vehicle, it is determined whether or not the window glass is in a fully closed state depending on whether or not the outside air temperature is in an intermediate temperature range. If air conditioning correction is performed with the air conditioning correction value taking into account the effects of solar radiation, and it is determined that any of the window glass is open, it will be affected by the passenger's upper body temperature and solar radiation, which are susceptible to solar radiation. The third air conditioning correction value is calculated according to the temperature difference of the abdomen, which is the lower part of the upper body of the occupant, which is a difficult part. And air conditioning correction for cold radiation can be performed.

  In addition, the airflow resistance of the window side is reduced by reducing the airflow resistance of the side face air outlet on the window side (that is, the opening area is larger) than the airflow resistance of the center face air outlet on the vehicle center side among the face air outlets for passengers in each air conditioning zone. Therefore, it is possible to always perform sufficient air-conditioning correction on the window side against overwhelming cold due to cold radiation and heat due to partial solar radiation, and to suppress overcorrection on the vehicle center side. .

  In addition, the influence of the first air conditioning correction value and the cold radiation that increase as the influence of the solar radiation increases the blowing ratio between the window-side air outlet and the central air outlet in the seat air conditioner. As the second air conditioning correction value that increases in response to the larger correction value, the blowing rate on the window side is increased, so even against uneven solar radiation, cold shoulder and knee cold Therefore, it is possible to sufficiently correct the seat air conditioning that can alleviate these effects.

(Other embodiments)
In the fifth embodiment, B.I. As explained in 4), when correcting the delay in the rise in the side window temperature, the rise in the side window temperature is caused by the change in the temperature of the occupant upper body temperature as a part affected by solar radiation other than the side window. The later minute was corrected. The correction method in the fifth embodiment is not limited to this, and can be variously changed as follows.

  Hereinafter, in various embodiments, steps that perform the same processing as the processing in the control routine of FIG. 26 of the fifth embodiment are denoted by the same reference numerals, description thereof is omitted, and only different steps are described.

  (1) As shown in FIG. 30, in step S331, as shown in Expression 27, the side window temperature may be corrected only by the increase ΔTPUDr (or ΔTPUPa) of the passenger upper body temperature for 4 seconds.

TSWDr * (current) = TSWDr * (4 seconds ago) + ΔTPUDr
TSWPa * (current) = TSWPa * (4 seconds ago) + ΔTPUPa
... (Formula 27)
As a result, it is possible to correct the amount by which the increase in the side window temperature is slower than the increase in the occupant upper body temperature.

  (2) As shown in FIGS. 24 and 25, the rear tray temperature MIN (C10, D10) is calculated based on the temperatures C10, D10 of the rear tray 91Rr detected by the Rr non-contact temperature sensor 7Rr used in the fifth embodiment. To do. Then, as shown in FIG. 31, it is determined in step S321 whether or not the rear tray temperature has risen more than 4 seconds ago. Furthermore, in step S332, as shown in Expression 28, the side window temperature may be corrected only by the increase in the rear tray temperature for 4 seconds.

TSWDr * (current) = TSWDr * (4 seconds ago) + rear tray temperature rise TSWPa * (current) = TSWDa * (4 seconds ago) + rear tray temperature rise
(Equation 28)
As a result, it is possible to correct the amount by which the rise in the side window temperature is slower than the rise in the rear tray temperature.

  (3) As in (2) above, it is determined in step S321 whether or not the rear tray temperature has risen, and in step S332, the above equation 28 is used to correct the amount by which the side window temperature rise is slower than the rear tray temperature rise. To do. Furthermore, in this example, in order to make the correction value of the side window temperature approach the true value immediately after the response is improved by Equation 29 in Step S341, the solar radiation on the Dr side and Pa side is obtained by Equation 29. After the change of direction, for example, when the correction of the side window temperature starts on the Pa side, the temperature difference response between the left and right (Dr side and Pa side) can be improved by lowering the Dr side correction temperature. .

TSWDr * (current) = TSWDr * (4 seconds ago)
-(TSWDr * (4 seconds ago) -TSWDr (current)) / 30
-(TSWPa * (4 seconds ago) -TSWPa (4 seconds ago)) / 30
TSWPa * (current) = TSWPa * (4 seconds ago)
-(TSWPa * (4 seconds ago) -TSWPa (current)) / 30
-(TSWDr * (4 seconds ago) -TSWDr (4 seconds ago)) / 30
(Equation 29)
(4) In the example shown in FIG. 33, as in the fifth embodiment, it is determined whether the occupant upper body temperature is rising (S320). Similarly to (1) above, in step S331, the side window temperature is calculated using Equation 27. The amount of increase in the vehicle's upper body temperature is slower than the increase in the passenger's upper body temperature. Furthermore, in this example, when the correction of the side window temperature on the Pa side (Dr side) is started by Equation 29 in Step S341, the correction temperature on the Dr side (Pa side) is lowered by the formula 29. The temperature difference response between the left and right (Dr side and Pa side) can be improved.

(Sixth embodiment)
Next, a sixth embodiment of the present invention will be described. The sixth embodiment is different from the first embodiment in that A.A. 5) A solar radiation sensor is provided to prevent malfunction of solar radiation correction. 5) The detected parts in the detection ranges of the non-contact temperature sensors 7Fr and 7Rr for Fr and Rr are different, and C.I. 5) The solar radiation correction value calculation method for correcting the target blowing temperature according to the influence of solar radiation is different from the first and third air conditioning correction value calculation methods. Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is simplified or omitted. 5), B.E. 5), C.I. 5) will be described.

  The air outlet arrangement state of the indoor air conditioning unit of the vehicle air conditioner in the sixth embodiment is shown in FIG. 1 as in the first embodiment. Further, the Fr-side or Rr-side center, the side face outlet, and the duct configuration are also shown in FIG. 3 as in the first embodiment. Description of these FIG. 1 and FIG. 3 is omitted.

  A. 5) The whole block diagram including the indoor air conditioning unit and the control block is shown in FIG. 34, which is partially different from the first embodiment. That is, in the sixth embodiment, solar radiation sensors 83a and 83b are connected to the input side of the air conditioner ECU 8.

  The solar radiation sensors 83a and 83b are well-known two-element (2D) type solar radiation sensors disposed at the frontmost part of the passenger compartment 1 and at the substantially central portion of the instrument panel 91Fr near the inside of the front window 90Fr in the left-right direction of the vehicle. It is. Among these, the solar radiation sensor 83a detects the solar radiation amount TsDr incident on the FrDr-side air conditioning zone 1a, and outputs the solar radiation amount signal TsDr to the air conditioner ECU 8. The solar radiation sensor 83b detects the solar radiation amount TsPa incident on the FrPa-side air conditioning zone 1b, and outputs the solar radiation amount signal TsPa to the air conditioner ECU 8. A 1D type solar radiation sensor 83r is also arranged near the left and right center of the rear tray 91Rr, which is the interior near the lower part of the rear window 90Rr at the rear of the vehicle interior 1, thereby detecting the amount of solar radiation particularly from the rear of the vehicle. The solar radiation amount signal can be used as appropriate.

  B. 5) The non-contact temperature sensors 7Fr and 7Rr for Fr and Rr have the structure shown in FIG. 4 as in the first embodiment. In the sixth embodiment, as shown in FIG. 35, the non-contact temperature sensor 7Fr is arranged in the overhead module 13 on the front side, and the non-contact temperature sensor 7Rr is the ceiling in the left and right center of the passenger on the Rr side. Is arranged. FIG. 36 shows an example of a detection range by the non-contact temperature sensor 7Fr as a rectangular block. That is, in the non-contact temperature sensors 7Fr and 7Rr, the size and position of each detection range can be arbitrarily set according to the arrangement of each lens 75 and each sensor element in FIG.

  In the sixth embodiment, the detected portions of the non-contact temperature sensors 7Fr and 7Rr are exemplified as matrix detection ranges on the Dr side in FIGS. 37A and 37B, respectively, and the vehicle in FIG. It is set as indicated by the positional relationship seen from above.

  That is, in the sixth embodiment, the Fr non-contact temperature sensor 7Fr calculates the surface temperature A12 of the FrDr side window 100a and the interior portion 101a below it, and the temperature A20 of the upper body of the FrDr occupant on the FrDr side. As the detected part, and the surface temperature B12 of the side window 100b on the FrPa side and the interior part 101b below it at the left-right symmetrical position of the vehicle, and the temperature C20 of the upper body of the FrPa passenger are used as the detected part on the FrPa side. , Respectively, are set and arranged.

  Similarly, the non-contact temperature sensor 7Rr for Rr includes the surface temperature C12 of the side window 100c on the RrDr side and the interior part 101c below it, and the temperature C20 of the upper body of the RrDr occupant as the detected part on the RrDr side, and The surface temperature D12 of the side window 100d on the RrPa side and the interior part 101d below it and the temperature D20 of the upper body of the RrPa occupant in the left-right symmetrical position of the vehicle are set and arranged as detected parts on the RrPa side, respectively. ing.

  Thus, in the sixth embodiment, the windows 100a to 100d and the window neighborhoods 101a to 101d are set as one detection range A12, B12, C12, and D12, respectively.

  Note that setting the window and the vicinity of the window to one detection range A12, B12, C12, D12 also means detecting the temperature at the lower part of each of the side windows 100a to 100d. Therefore, even if the side windows 100a to 100d are opened at the top for ventilation in the passenger compartment due to smoking by passengers, etc., there is glass at the bottom of the window, which can accurately detect the window temperature. it can.

  C. 5) The operation in the sixth embodiment is basically the same as in the first embodiment, and the basic air conditioning control is performed by the air conditioner ECU 8 according to the main routine shown in FIG. Front seat air conditioning processing and rear seat air conditioning processing are performed.

  However, the target blowing temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa in the air conditioning zones 1a to 1d, which are basic expressions of the air conditioning control, are calculated using the following Expression 30, Expression 31, Expression 32, and Expression 33, respectively. . Further, the target opening degrees θ1, θ2, θ3, and θ4 of each air mix door are calculated by Expression 3, Expression 4, Expression 7, and Expression 8, respectively, as in the first embodiment.

TAOFrDr = KsetFr × TsetFrDr−KrFr × TrFr
−KamFr × Tam−KsFr × FrTsDr + CFr
+ FrSunDr (Equation 30)
TAOFrPa = KsetFr × TsetFrPa−KrFr × TrFr
−KamFr × Tam−KsFr × FrTsPa + CFr
+ FrSunPa (Formula 31)
TAORrDr = KsetRr × TsetRrDr−KrRr × TrRr
−KamRr × Tam−KsRr × RrTsDr + CRr
+ RrSunDr (Formula 32)
TAORrPa = KsetRr × TsetRrPa−KrRr × TrRr
−KamRr × Tam−KsRr × RrTsPa + CRr
+ RrSunPa (Formula 33)
Note that TsetFrDr, TsetFrPa, TsetRrDr, and TsetRrPa are set temperature signals in the air-conditioning zones 1a, 1b, 1c, and 1d, TrFr and TrRr are Fr side and Rr side inside air temperature signals, Tam is an outside air temperature signal, FrTsDr and FrTsPa, respectively. Are detection signals from the solar radiation sensors 83a and 83b, and RrTsDr and RrTsPa are detection signals from the solar radiation sensors 83a and 83b, respectively.

  Further, KsetFr, KsetRr, KrFr, KrRr, KamFr, KamRr, KsFr, KsRr, the gain of each signal, CFr, CRr are constants.

  Further, FrSunDr, FrSunPa, RrSunDr, and RrSunPa correct the target blowing temperature in each of the air-conditioning zones 1a, 1b, 1c, and 1d according to the detected temperatures detected by the non-contact temperature sensors 7Fr and 7Rr, respectively. It is a solar radiation correction amount as an air-conditioning correction value.

  Here, calculation processing of the solar radiation correction amounts FrSunDr, FrSunPa, RrSunDr, and RrSunPa will be described based on a target blowing temperature calculation routine shown in FIG. The calculation routine of FIG. 38 is performed in common in step S123 in the main routine of FIG. 8 for all the air conditioning zones 1a to 1d.

  First, in step S400, factors f19 and f22 for preventing a solar radiation correction malfunction when there is no solar radiation are calculated. That is, the factor f19 for the Dr side is calculated as a value that increases from 0 to 1 as the product of the solar radiation amount FrTsDr on the Dr side and the coefficient f24 increases based on the map shown in the block of S400. Is done.

  The coefficient f24 is set as a value between 0 and 1 according to the Fr-side solar radiation amount ratio FrTsDr / Σ based on the map shown in the block of S400. However, Σ = FrTsDr + FrTsPa, and when Σ = 0, the solar radiation amount ratio FrTsDr / Σ = 0.

  That is, in the calculation on the Dr side, the solar radiation correction is not performed by setting the solar radiation amount ratio FrTsDr / Σ <0.5 and f24 = 0. Similarly, the coefficient f25 and the factor f22 are calculated on the Pa side.

  In the next step S410, solar radiation correction amounts FrSunDr, FrSunPa, RrSunDr, RrSunPa are calculated.

  Specifically, in the calculation on the FrDr side, the FrDr side solar radiation correction value f17 is based on the map shown in the block of S410 and the FrDr side window 100a that is a detection signal of the non-contact temperature sensor 7Fr and its window As the difference (A12-B12) between the temperature A12 of the nearby interior portion 101a and the temperature B12 of the symmetrical FrPa side window 100b and the interior portion 101b near the window increases, it becomes smaller than 0, that is, a negative value. Is calculated to be large.

  The solar radiation correction amount FrSunDr on the FrDr side is calculated as the product of the FrDr side solar radiation correction value f17 and the factor f19, FrSunDr = f17 × f19 (≦ 0). As a result, as the temperature on the FrDr side due to solar radiation rises higher than the temperature on the FrPa side, the negative correction value FrSunDr on the FrDr side increases, and the target blowout temperature TAOFrDr is lowered to control the air conditioning of the air conditioning zone 1a. Correct to the cooling side.

  Similarly, in the calculation on the RrDr side, the RrDr side solar radiation correction value f18 is calculated based on the map shown in the block of S410 and the RrDr side window 100c that is a detection signal of the non-contact temperature sensor 7Rr and the vicinity of the window. The larger the difference (C12−D12) between the temperature C12 of the interior part 101c and the temperature D12 of the symmetrical RrPa side window 100d and the interior part 101d near the window is smaller than 0, that is, the negative value is larger. Is calculated as follows.

  The RrDr-side solar radiation correction amount RrSunDr is calculated as the product of the RrDr-side solar radiation correction value f18 and the factor f19, RrSunDr = f18 × f19 (≦ 0). As a result, as the temperature on the RrDr side due to solar radiation rises higher than the temperature on the RrPa side, the solar radiation correction amount RrSunDr on the RrDr side becomes a negative value, and the target blowing temperature TAORrDr is lowered to control the air conditioning of the air conditioning zone 1c. Correct to the cooling side.

  Similarly, on the Pa side, the FrPa side solar radiation correction value f20 is based on the map shown in the block of S410, and the FrPa side window 100b that is a detection signal of the non-contact temperature sensor 7Fr and the interior portion 101b in the vicinity of the window. As the difference (B12-A12) between the temperature B12 of the vehicle and the temperature A12 of the window 100a on the FrDr side in the different direction of the vehicle, that is, the symmetrical position, and the interior portion 101a in the vicinity of the window becomes smaller, it becomes smaller than 0. The negative value is calculated to be large.

  The solar radiation correction amount FrSunPa on the FrPa side is calculated as the product of the FrPa side solar radiation correction value f20 and the factor f22, FrSunPa = f20 × f22 (≦ 0). As a result, as the FrPa side temperature due to solar radiation rises higher than the FrDr side temperature, the FrPa side solar radiation correction amount FrSunPa becomes a negative value, and the target blowout temperature TAOFrPa is lowered to control the air conditioning of the air conditioning zone 1b. Correct to the cooling side.

  Similarly, in the RrPa-side calculation, the RrPa-side solar radiation correction value f21 is calculated based on the map shown in the block of S410 and the RrPa-side window 100d that is the detection signal of the non-contact temperature sensor 7Rr and the vicinity of the window. The difference (D12-C12) between the temperature D12 of the interior part 101d and the temperature C12 of the window 100c on the RrDr side in the different direction of the vehicle, that is, the right and left symmetrical position, and the interior part 101c in the vicinity of the window increases. That is, the negative value is calculated to be large.

  The RrPa-side solar radiation correction amount RrSunPa is calculated as the product of the RrPa-side solar radiation correction value f21 and the factor f22, RrSunDr = f21 × f22 (≦ 0). As a result, as the temperature on the RrPa side due to solar radiation rises higher than the temperature on the RrDr side, the solar radiation correction amount RrSunPa on the RrPa side becomes a negative value, and the target blowing temperature TAORrPa is lowered to control the air conditioning in the air conditioning zone 1d. Correct to the cooling side.

  Then, in step S420, using the solar radiation correction amounts FrSunDr, FrSunPa, RrSunDr, RrSunPa calculated in this way, the target blowing temperatures TAOFrDr, TAOFrPa, TAORrDr, TAORrPa is calculated.

  As described above, in the sixth embodiment, the air conditioning correction value according to the temperature difference (A12−B12) and (B12−A12) between the FrDr and FrPa windows in different directions of the vehicle and the interior portion in the vicinity of the window. The solar radiation correction amounts FrSunDr and FrSunPa are calculated, and the air conditioning control is performed by correcting the target blowing temperatures TAOFrDr and TAOFrPa based on the solar radiation correction amounts FrSunDr and FrSunPa. Similarly, the solar radiation correction amounts RrSunDr, RrSunPa as air conditioning correction values according to the temperature difference (C12-D12), (D12-C12) of the windows of the RrDr and RrPa in different directions of the vehicle and the interior parts near the windows. Is calculated, and air conditioning control is performed by correcting the target blowing temperatures TAORrDr and TAORrPa based on the solar radiation correction amounts RrSunDr and RrSunPa.

  In the case of a vehicle, the occupant feels the hottest during low-elevation solar radiation where the occupant's face is exposed to solar radiation. The windows, particularly the side windows, are exposed to sunlight at an angle close to a right angle with respect to the glass surface during low elevation solar radiation, and this raises the temperature of the window and the vicinity thereof. On the other hand, during low elevation solar radiation, the occupant's sense of warmth due to accurate solar radiation cannot be grasped depending on the amount of solar radiation detected by the solar radiation sensor.

  As described above, by comparing the windows in different directions of the vehicle and the temperatures in the vicinity of the windows, the direction of solar radiation can be grasped, and further, the intensity of solar radiation can be grasped by the temperature difference therebetween. Therefore, by using the window and the temperature in the vicinity of the window, it is possible to perform air-conditioning control that reflects the occupant's thermal feeling during low elevation solar radiation. Further, since the temperature in the vicinity of the window is used, it is possible to detect solar heat without erroneous detection even when the window is opened.

  Furthermore, since the window and the temperature in the vicinity of the window in each of the different directions are detected in one detection range, the system can be simplified by reducing the number of sensor elements in the non-contact temperature sensor.

It is placed on the passenger compartment ceiling at the left and right center of the passenger. And the to-be-detected part of non-contact temperature sensor 7Fr, 7Rr is shown as a rectangular detection range in FIG. 40, and is set so that it may be shown by the positional relationship seen from the vehicle upper direction of FIG.

  That is, in the seventh embodiment, the Fr non-contact temperature sensor 7Fr includes a surface temperature A11 of the side window 100a on the FrDr side, and a surface temperature B11 of the side window 100b on the FrPa side at the left-right symmetrical position of the vehicle. The instrument panel, which is an interior part near the front window 90Fr, that is, the surface temperature F11 of the instrument panel 91Fr is set and arranged as a detected part.

The surface temperature R11 of the rear tray 91Rr, which is the interior part, is set and arranged as a detected part.

  Note that the temperature detection ranges A11 to D11 of the side windows 100a to 100d in the seventh embodiment are respectively set at the lower part of the window. Therefore, even if the side windows 100a to 100d are opened at the top for ventilation in the passenger compartment due to smoking by passengers, etc., there is glass at the bottom of the window, which can accurately detect the window temperature. it can.

  B. 6) The operation in the seventh embodiment basically follows the main routine shown in FIG. 8 by the air conditioner ECU 8 as the basic air conditioning control, as in the first and sixth embodiments. Front seat air conditioning control and rear seat air conditioning control are performed according to the control map. Similarly to the sixth embodiment, the target blowing temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa in the air-conditioning zones 1a to 1d, which are basic expressions of the air-conditioning control, are expressed by Expression 30, Expression 31, Expression 32, and Expression 33, respectively. Is calculated using

  However, in the seventh embodiment, the instrument panel 91Fr which is an interior portion near the side window and the lower front window, or the rear tray which is an interior portion near the lower rear window, is detected in two different directions from the sixth embodiment. According to this, the calculation routine of the target blowing temperature shown in FIG. 42 is partially different from the calculation routine of FIG. 38 in the sixth embodiment. In the following, steps that perform the same processing as in the sixth embodiment are denoted by the same reference numerals, description thereof is omitted, and different processing contents will be described.

  In step S400, as in the sixth embodiment, factors f19 and f22 are calculated. In the next step S411, solar radiation correction amounts FrSunDr, FrSunPa, RrSunDr, RrSunPa are calculated.

  Specifically, in the calculation on the FrDr side, the FrDr-side solar radiation correction value f17 is based on the map shown in the block of S411, and the temperature A11 of the FrDr-side window 100a that is a detection signal of the non-contact temperature sensor 7Fr. As the absolute value | A11−F11 | of the difference from the temperature F11 of the instrument panel 91Fr, which is the interior portion near the lower part of the front window 90Fr in a different direction, increases, it becomes smaller than 0, that is, a negative value increases. It is calculated as follows.

  The solar radiation correction amount FrSunDr on the FrDr side is calculated as the product of the FrDr side solar radiation correction value f17 and the factor f19, FrSunDr = f17 × f19 (≦ 0). As a result, as the temperature on the FrDr side due to solar radiation rises higher than the temperature of the instrument panel, or as the temperature of the instrument panel due to solar radiation rises above the temperature on the FrDr side, the solar radiation correction amount FrSunDr becomes a negative value. The temperature TAOFrDr is lowered to correct the air conditioning control of the air conditioning zone 1a to the cooling side.

  Similarly, in the calculation on the RrDr side, the RrDr side solar radiation correction value f18 is calculated based on the map shown in the block of S411, the temperature C11 of the window 100c on the RrDr side that is a detection signal of the non-contact temperature sensor 7Rr, and The absolute value | C11−R11 | of the difference with the temperature R11 of the rear tray 91Rr, which is the interior portion near the lower portion of the rear window 90Rr in a different direction, is calculated to be smaller than 0, that is, to increase the negative value. Is done.

  The RrDr-side solar radiation correction amount RrSunDr is calculated as the product of the RrDr-side solar radiation correction value f18 and the factor f19, RrSunDr = f18 × f19 (≦ 0). As a result, as the temperature on the RrDr side due to solar radiation rises higher than the temperature of the rear tray, or as the temperature of the rear tray due to solar radiation rises above the temperature on the RrDr side, the solar radiation correction amount RrSunDr becomes a negative value, and the target blowout The temperature TAORrDr is decreased to correct the air conditioning control of the air conditioning zone 1c to the cooling side.

  Similarly, on the Pa side, the FrPa side solar radiation correction value f20 is different from the temperature B11 of the FrPa side window 100b, which is a detection signal of the non-contact temperature sensor 7Fr, based on the map shown in the block of S411. The absolute value | B11−F11 | of the difference from the temperature F11 of the instrument panel 91Fr that is the interior portion near the lower portion of the front window 90Fr in the direction is calculated so as to become smaller than 0, that is, to increase the negative value.

  The solar radiation correction amount FrSunPa on the FrPa side is calculated as the product of the FrPa side solar radiation correction value f20 and the factor f22, FrSunPa = f20 × f22 (≦ 0). As a result, as the temperature on the FrPa side due to solar radiation rises above the temperature of the instrument panel, or as the instrument panel temperature due to solar radiation rises above the temperature on the FrPa side, the solar radiation correction amount FrSunPa becomes a negative value, and the target blowout The temperature TAOFrPa is lowered to correct the air conditioning control of the air conditioning zone 1b to the cooling side.

  Similarly, in the RrPa-side calculation, the RrPa-side solar radiation correction value f21 is calculated based on the map shown in the block of S411, and the temperature D11 of the RrPa-side window 100d, which is a detection signal of the non-contact temperature sensor 7Rr, The absolute value | D11-R11 | of the difference between the rear tray 91Rr and the temperature R11 of the interior near the rear window 90Rr in a different direction is calculated to be smaller than 0, that is, to have a negative value larger as the absolute value | D11-R11 | Is done.

  The RrDr-side solar radiation correction amount RrSunDr is calculated as the product of the RrDr-side solar radiation correction value f21 and the factor f22, RrSunPa = f21 × f22 (≦ 0). As a result, as the temperature on the RrPa side due to solar radiation rises higher than the temperature of the rear tray or as the temperature of the rear tray due to solar radiation rises above the temperature on the RrPa side, the solar radiation correction amount RrSunPa becomes a negative value, and the target blowout The temperature TAORrPa is lowered to correct the air conditioning control of the air conditioning zone 1d to the cooling side.

  Then, in step S420, the target blowing temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa of the air conditioning zones 1a to 1d are calculated based on the equations 30 to 33.

  As described above, in the seventh embodiment, the temperature difference between the side window and the instrument panel that is the interior portion near the front window in a different direction of the vehicle | A11−F11 |, | B11−F11 | The solar radiation correction amounts FrSunDr, FrSunPa, RrSunDr, and RrSunPa as the air conditioning correction values according to the temperature differences | C11-R11 |, | D11-R11 | from the rear tray near the rear window in different directions of the vehicle. The air conditioning control is performed by correcting the target blowing temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa based on the calculated solar radiation correction amounts FrSunDr, FrSunPa, RrSunDr, and RrSunPa.

  In the case of a vehicle, the occupant feels the hottest during low-elevation solar radiation where the occupant's face is exposed to solar radiation. The windows, particularly the side windows, are exposed to solar radiation at an angle close to a right angle with respect to the glass surface during low elevation solar radiation, which increases the temperature of the window, and thus correlates with the warmth of the passenger. On the other hand, during low elevation solar radiation, the occupant's sense of warmth due to accurate solar radiation cannot be grasped depending on the amount of solar radiation detected by the solar radiation sensor.

  As described above, by comparing the temperature of the side window in different directions of the vehicle and the instrument panel or rear tray, which is the interior part in the vicinity of the front window or the rear window, the direction of solar radiation can be grasped, and the temperature difference between them. Can grasp the intensity of solar radiation. Therefore, by using the temperature in the vicinity of the side window and the window, it is possible to perform air-conditioning control that reflects the occupant's warm feeling during low elevation solar radiation.

  Furthermore, since the temperature in the different directions or the temperature in the vicinity of the window is detected in one detection range, the system can be simplified by reducing the number of sensor elements in the non-contact temperature sensor.

  The solar radiation correction amount FrSunDr on the FrDr side is calculated as the product of the FrDr side solar radiation correction value f17 and the factor f19, FrSunDr = f17 × f19 (≦ 0). As a result, as the temperature on the FrDr side due to solar radiation rises above the temperature of the front window, or as the temperature of the front window due to solar radiation rises above the temperature on the FrDr side, the solar radiation correction amount FrSunDr becomes a negative value. The target blowing temperature TAOFrDr is lowered to correct the air conditioning control of the air conditioning zone 1a to the cooling side.

The difference is that the instrument panel 91Fr or the rear tray 91Rr, which is the interior part near the rear window, is different. Accordingly, the target blowout temperature calculation routine shown in FIG. 48 differs from the calculation routine of FIG. 38 in the sixth embodiment. The department is different. In the following, steps that perform the same processing as in the sixth embodiment are denoted by the same reference numerals, description thereof will be omitted, and different processing contents will be described.

  In step S400, as in the sixth embodiment, factors f19 and f22 are calculated. In the next step S413, solar radiation correction amounts FrSunDr, FrSunPa, RrSunDr, RrSunPa are calculated.

  Specifically, in the calculation on the FrDr side, the FrDr side solar radiation correction value f17 is based on the map shown in the block of S413, and the FrDr side window 100a that is a detection signal of the non-contact temperature sensor 7Fr and its window The larger the absolute value | A12−F11 | of the difference between the temperature A12 of the nearby interior portion 101a and the temperature F11 of the instrument panel 91Fr that is the interior portion near the lower front window 90Fr in a different direction is smaller than 0. That is, the negative value is calculated to be large.

  The solar radiation correction amount FrSunDr on the FrDr side is calculated as the product of the FrDr side solar radiation correction value f17 and the factor f19, FrSunDr = f17 × f19 (≦ 0). As a result, as the temperature on the FrDr side due to solar radiation rises higher than the temperature of the instrument panel, or as the temperature of the instrument panel due to solar radiation rises above the temperature on the FrDr side, the solar radiation correction amount FrSunDr becomes a negative value. The temperature TAOFrDr is lowered to correct the air conditioning control of the air conditioning zone 1a to the cooling side.

  Similarly, in the calculation on the RrDr side, the RrDr side solar radiation correction value f18 is calculated based on the map shown in the block of S413 and the window 100c on the RrDr side that is the detection signal of the non-contact temperature sensor 7Rr and the vicinity of the window 100c. The larger the absolute value | C12−R11 | of the difference between the temperature C12 of the interior portion 101c and the temperature R11 of the rear tray 91Rr, which is the interior portion near the lower portion of the rear window 90Rr in a different direction, is smaller than 0. The negative value is calculated to be large.

  The RrDr-side solar radiation correction amount RrSunDr is calculated as the product of the RrDr-side solar radiation correction value f18 and the factor f19, RrSunDr = f18 × f19 (≦ 0). As a result, as the temperature on the RrDr side due to solar radiation rises higher than the temperature of the rear tray or as the temperature of the rear tray due to solar radiation rises higher than the temperature on the RrDr side, the solar radiation correction amount RrSunDr becomes a negative value and the target blowout The temperature TAORrDr is decreased to correct the air conditioning control of the air conditioning zone 1c to the cooling side.

  Similarly, on the Pa side, the FrPa side solar radiation correction value f20 is based on the map shown in the block of S413, and the FrPa side window 100b that is a detection signal of the non-contact temperature sensor 7Fr and the interior portion 101b in the vicinity of the window. The absolute value | B12−F11 | of the difference between the temperature B12 of the instrument panel 91Fr and the temperature F11 of the instrument panel 91Fr in the interior near the front window 90Fr in a different direction is smaller, that is, a negative value. Is calculated to be large.

  The solar radiation correction amount FrSunPa on the FrPa side is calculated as the product of the FrPa side solar radiation correction value f20 and the factor f22, FrSunPa = f20 × f22 (≦ 0). As a result, as the temperature on the FrPa side due to solar radiation rises above the temperature of the instrument panel, or as the instrument panel temperature due to solar radiation rises above the temperature on the FrPa side, the solar radiation correction amount FrSunPa becomes a negative value, and the target blowout The temperature TAOFrPa is lowered to correct the air conditioning control of the air conditioning zone 1b to the cooling side.

  Similarly, in the calculation on the RrPa side, the RrPa side solar radiation correction value f21 is calculated based on the map shown in the block of S411 and the window 100d on the RrPa side that is the detection signal of the non-contact temperature sensor 7Rr and the vicinity of the window. As the absolute value | D12−R11 | of the difference between the temperature D12 of the interior portion 101d and the temperature R11 of the rear tray 91Rr, which is an interior portion near the rear window 90Rr in a different direction, becomes smaller, that is, The negative value is calculated to be large.

  The RrDr-side solar radiation correction amount RrSunDr is calculated as the product of the RrDr-side solar radiation correction value f21 and the factor f22, RrSunPa = f21 × f22 (≦ 0). As a result, as the temperature on the RrPa side due to solar radiation rises higher than the temperature of the rear tray or as the temperature of the rear tray due to solar radiation rises above the temperature on the RrPa side, the solar radiation correction amount RrSunPa becomes a negative value, and the target blowout The temperature TAORrPa is lowered to correct the air conditioning control of the air conditioning zone 1d to the cooling side.

  Then, in step S420, the target blowing temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa of the air conditioning zones 1a to 1d are calculated based on the equations 30 to 33.

  Thus, in the ninth embodiment, the temperature difference | A12−F11 |, | B12−F11 | between the side window and the instrument panel that is the interior portion in the vicinity of the front window in a different direction of the vehicle, or the side window Calculate solar radiation correction amounts FrSunDr, FrSunPa, RrSunDr, and RrSunPa as air conditioning correction values according to the temperature difference | C12-R11 |, | D12-R11 | Then, the air conditioning control is performed by correcting the target blowing temperatures TAOFrDr, TAOFrPa, TAORrDr, and TAORrPa based on the solar radiation correction amounts FrSunDr, FrSunPa, RrSunDr, and RrSunPa.

  In the case of a vehicle, the occupant feels the hottest during low-elevation solar radiation where the occupant's face is exposed to solar radiation. The windows, particularly the side windows, are exposed to sunlight at an angle close to a right angle with respect to the glass surface during low elevation solar radiation, and this raises the temperature of the window and the vicinity thereof. On the other hand, during low elevation solar radiation, the occupant's sense of warmth due to accurate solar radiation cannot be grasped depending on the amount of solar radiation detected by the solar radiation sensor.

  As described above, the direction of solar radiation can be grasped by comparing the temperature of the side window in the different direction of the vehicle and its neighboring interior parts with the front window or the rear window, and the intensity of solar radiation can be further increased by the temperature difference between them. I can grasp. Therefore, by using the temperature in the vicinity of the side window and the window, it is possible to perform air-conditioning control that reflects the occupant's warm feeling during low elevation solar radiation. Further, since the temperature in the vicinity of the window is used, it is possible to detect solar heat without erroneous detection even when the window is opened.

  In addition, the side window and the interior part in the vicinity thereof and the instrument panel or the rear tray are used as the visual field range as the detection range, so that, for example, a non-contact temperature with a relatively narrow viewing angle than when the side window or the front window is used as the visual field range. A sensor can be used.

  Furthermore, since the temperature in the different directions or the temperature in the vicinity of the window is detected in one detection range, the system can be simplified by reducing the number of sensor elements in the non-contact temperature sensor.

(Modification)
In each of the above embodiments, as the temperature detection means, the FrDr and FrPa air-conditioning zones 1a and 1b are detected in a matrix form by the Fr non-contact temperature sensor 7Fr disposed on the ceiling in the center of the front seat. Although an example in which the air-conditioning zones 1c and 1d of RrDr and RrPa are detected in a matrix by the arranged non-contact temperature sensor for Rr 7Rr is shown, the present invention is not limited to this.

  By using a dedicated matrix IR sensor for each air-conditioning zone and placing it on the ceiling above the occupant of each seat and near the window, it is easily affected by solar radiation from the side window to the upper body of the occupant's window. Temperature can be detected.

  Further, instead of the matrix IR sensor as the non-contact temperature sensor, a two-dimensional heat distribution diagram may be created by scanning the infrared light receiving range of the heat detection element in a one-dimensional direction or a two-dimensional direction. Thereby, the number of heat detection elements can be reduced.

  Further, the temperature detecting means is not limited to the non-contact temperature sensor, and for example, the temperature detecting element may be directly arranged on a detected part such as an interior part.
