The microcomputer 190 operates by being supplied with power from the battery B via the ignition switch IG of the vehicle, and starts executing the computer program in response to the operation of the auto switch Sauto on the operation panel P.

By the way, in this embodiment, attention was paid to the following in calculating the preference amount Tk representing the preference state of the occupant in the air-conditioning control state. That is, in order to individually realize an air-conditioning control state that suits each occupant's preference, environmental factors such as temperature and airflow that affect the sensation of each occupant, and human factors such as the amount of clothing and exercise of each occupant are considered. Need to be considered individually. Therefore, based on these individual environmental factors and human factors, a standard thermal sensation that the majority of people will feel is calculated, and thereafter, every time the air conditioning control conditions are changed according to each passenger's individual preference, the same is calculated. Each change amount,
The basic temperature is stored in time series for each standard thermal sensation at the time of each change, and each preference amount is individually calculated for each standard thermal sensation from each time series change amount. If the occupant's preference is learned for each standard thermal sensation as a parameter of, even if various thermal environment factors change, comfortable air conditioning control suited to each occupant's preference can be achieved individually without frequent setting operations. Therefore, based on this attention, the calculation and learning of the favorite amount Tk and the calculation of the required blowing temperature Tao of the airflow into the vehicle compartment are performed as follows.

Thus, the following equations (1) and (2) are employed for calculating the desired amount Tk and the required blowing temperature Tao.

[0019]

[Equation 1] Tk = f (△ TMA, TSENS)

[0020]

## EQU2 ## where Tao = Kset.Tset-Kr.Tr-Kam.Tam-Ks.Ts + Tk. In the equation (1), the symbol .DELTA.TMA is a warm feeling switch 90a or 9 which is made according to the occupant's preference at a certain air conditioning control time.

The symbol TSENS represents a standard thermal sensation in the environment when the thermal sensation switch 90a or 90b is operated, and is a standard new effective temperature calculated based on a calorific value calculation formula regarding a known standard new effective temperature SET * described later. SET *.

Therefore, Equation 1 indicates that the preference amount Tk is specified as a function of the warming operation change amount average value ΔTMA and the warming feeling TSENS. Then, the thermal operation change amount average value ΔT
Corresponds to the value MA is sequential learning, will be sequentially learned and stored in the microcomputer 190 as in the example shown in the occupant in the following Table 1 maps every ΔTM for each TSENS in the air-conditioning control timing preferences.

[0022]

[Table 1]

In Equation 2, each code Kset, Kr,
Kam and Ks represent a set temperature gain, an inside temperature, an outside temperature gain, and a solar radiation gain, respectively. Equation 2 is stored in the ROM of the microcomputer 190 in advance.

In this embodiment configured as described above,
It is assumed that the vehicle is driven by starting the engine of the vehicle based on the closing of the ignition switch IG. If the auto switch Sauto is operated at the time Time = T0 (see FIG. 5), the microcomputer 190
According to the flowcharts of FIGS. 3 and 4, execution of the computer program is started in step 200, initialization processing is performed in step 210, and each output signal from the operation panel P, A- D converter 180
, And a wind speed detection signal from the wind speed sensor 170 are input. However, a desired set temperature Tset in the cabin of the vehicle (prestored in the ROM of the microcomputer 190 as 25 (° C.)) is read from the ROM at step 210. Further, it is assumed that the preference amount Tk of the air conditioning control by the occupant has been initialized to Tk = 0 (see Time = T0 in FIG. 5) in step 210.

After that, the microcomputer 190
In step 230, it is determined whether any of the first to third personal selection signals from the operation panel P has been generated. At this stage, if it is assumed in step 220 that the first personal selection signal has been input from the personal selection switch 80a of the operation panel P, the microcomputer 190 advances the computer program to step 240. Then, this step 240

When the calculation in step 240 is completed in this way, the microcomputer 190 determines in step 250 whether the amount of thermal sensation has been changed by operating at least one of the two thermal sensation switches 90a and 90b. Determine. Thus, in step 220, no new input has been made from at least one of the two warm-up switches 90a, 90b (Time = T0 to
Therefore, the microcomputer 190 determines “NO” in step 250 based on the determination that the amount of thermal sensation has not changed. Therefore, at this stage, since the change control timer built in the microcomputer 190 is stopped, the microcomputer 190
It is determined as "NO" at 0, and the computer program proceeds to the next step 270. However, the above-mentioned change control timer operates in response to a new input from at least one of the two temperature sensation switches 90a, 90b during related control required in accordance with this input.

When the computer program proceeds to step 270 as described above, the microcomputer 190

[0028]

Tk = KM.multidot.TMA where, in equation (3), the symbol KM represents a coefficient. The equation 3 corresponds to the equation 1, and the microcomputer 190
Is stored in advance in the ROM. Thereafter, in the next step 280, the microcomputer 190 determines the set temperature Tset in the step 210, the inside temperature Tr, the outside temperature Tam and the amount of solar radiation Ts in the step 220, and the preference amount Tk in the step 270 based on the equation (2). According to 0, the required blowing temperature Tao of the airflow into the vehicle compartment is calculated.

When the calculation of the required outlet temperature Tao is completed in this way, the microcomputer 190 determines in step 290 the outlet temperature Te in step 220 and the required outlet temperature Tao in step 280 based on the following equation (4). The target opening degree SWo of the air mix damper 50 is calculated.

[0030]

## EQU00004 ## SWo = {(Tao-Te) / (Kw-Te)}. Times.100 (%) In Equation 4, the sign Kw represents a constant. Next, the microcomputer 190 determines the blowing mode according to the required blowing temperature Tao in step 280 based on a blowing mode pattern (see FIG. 6A) indicating the relationship between the blowing mode and the required blowing temperature Tao, and Based on the inside / outside air introduction mode pattern (see FIG. 6B) showing the relationship between the inside / outside air introduction mode 20 and the required blowing temperature Tao, the introduction mode is determined according to the required blowing temperature Tao, and the target feed of the blower 30 is performed. Based on Q-Tao data (see FIG. 6C) representing the relationship between the air volume Q and the required blowing temperature Tao, the target blowing volume Q is determined according to the required blowing temperature Tao in step 280.
The expression 4, the balloon mode pattern and the Q-Tao data are stored in the ROM of the microcomputer 190 in advance.

Next, the microcomputer 190
In step 300, the calculated target opening degree SWo, the determined blowing mode, the determined introduction mode, and the determined target air flow rate Q in step 290 are given as output signals to the servo motor 50a, the servo motor 70a, the servo motor 20a, and the drive circuit 30a, respectively. . For this reason, the servo motor 50a calculates the air mix damper 50 by the target opening degree SWo.
The servo motor 70a drives the outlet switching damper 70 to be in the determined blowing mode, and the servo motor 20a drives the inside / outside air switching damper 20.
Is driven to switch to the determined introduction mode, and the drive circuit 30a drives the blower 30 via the blower motor M so as to introduce the target air volume Q.

When the air flow introduced by the blower 30 into the air duct 10 via the inside / outside air switching damper 20 is cooled by the evaporator 40, a part of the cooling air flow is changed to the target of the air mix damper 50. Opening S
In accordance with Wo, the heater core 60
0, and flows toward the outlet switching damper 70, while the remaining cooling air flows directly through the air mix damper 50 toward the outlet switching damper 70 and mixes with the above-described heated air flow. Next, the mixed air flow is blown out as a blown air flow from at least one of the blowout port 13 and the blowout port 14 through the blowout port switching damper 70 into the vehicle interior at the required blowout temperature Tao. As a result, the air-conditioning temperature control in the vehicle compartment at the desired amount Tk = 0 is properly performed.

In the repetitive state of the arithmetic control as described above, when Time = T1 and T2 (see FIG. 5) are successively reached, the occupant feels the heat and presses the warm switch 90b twice. It is assumed that the reduced temperature sensation signal (see FIG. 5) is generated twice. Then, the microcomputer 1
In step 220, the CPU 90 determines “YES” based on the determination that the two thermal sensation signals are to be changed in step 220. However, in the present embodiment, an interruption program additionally stored in the ROM of the microcomputer 190 in advance responds to the operation of the warm-up switch 90a or 90b performed at each air conditioning control timing desired by the occupant as follows. Is executed. That is, in response to the operation of the warm-up switch 90a or 90b, the warm-up amount change input flag is set, and at the end of the operation, the warm-up amount change input timer (built-in the microcomputer 190) is reset and started to execute the predetermined warm-up. Sensitivity change time Tin (see FIG. 5)
, And the set state of the thermal sensation amount change input flag is maintained during that time.

At this stage, since the counting of the warming amount change input timer is not completed and the setting of the warming amount change input flag is maintained, the microcomputer 190 determines in step 310 that "NO , And a control change completion flag is set in step 310a (see Time = T1 in FIG. 5).
Based on the above, the occupant's preference amount Tk for air-conditioning control is calculated in accordance with the amount of change in warm operation 操作 TM (corresponding to the amount of change (−2 △ TU) by the two operations of the warm switch 90b at this stage).

[0035]

Tk = KM】 ΔTM However, at this stage, the calculation of the favorite amount TK is performed by using the expression (5) in order to provide a control that gives the operational feeling when operating the warm-up switch. Therefore, normally, Tk is calculated based on the equation (3), and control reflecting the past history is realized. Note that Equation 5 is stored in the ROM of the microcomputer 190 in advance.

If the determination at step 310 is "YES" at Time = T3 (see FIG. 5), the microcomputer 190 determines at step 320 the temperature change amount .DELTA. Calculated as the amount of change (−2 △ TU) due to the two operations of the sense switch 90b, and in step 330, the warm feeling in relation to the standard new effective temperature SET * at the time of determining “YES” in step 250 The operation change amount average value △ TMA is obtained from the above map △ TMA = 0.
Then, the average value obtained by adding the current change amount (−2UTU) to this value is updated as the thermal operation operation change amount average value ΔTMA and stored in the map (Time in FIG. 5). = T3-T4
reference). Then, the microcomputer 190 resets the control change completion flag in step 340 and starts reset start of a change control timer (built-in the microcomputer 190) (see Time = T4 in FIG. 5). For this reason, the change control timer sets a predetermined change control time Tc.
(See FIG. 5). Further, in step 350, the microcomputer 190 calculates the favorite amount Tk based on the equation 5 in accordance with the warming operation change amount ΔTM in step 320.

As described above, after the determination of "NO" or "YES" in step 310, step 350
Is calculated in step 280, the microcomputer 190 proceeds to step 280.
Set temperature Tset in step 210, step 220
The required blowing temperature Tao is calculated based on Equation 2 in accordance with the inside air temperature Tr, the outside air temperature Tam, and the amount of solar radiation Ts. Then, in step 290, the microcomputer 190 calculates the target opening degree SWo of the air mix damper 50 based on the required blowing temperature Tao and the outlet temperature Te in step 220 based on Equation 4, and calculates the blowing mode pattern, Based on the inside / outside air introduction mode pattern and the Q-Tao data, the blowout mode, the introduction mode, and the target airflow Q are determined according to the latest necessary blowout temperature Tao in step 280.

Thereafter, the result of each of these determinations is
00, the servo motor 50
a, the servo motor 70a, the servo motor 20a, and the drive circuit 30a. For this reason, the opening degree of the air mix damper 50, the blowing mode of the outlet switching damper 70, the introduction mode of the inside / outside air switching damper 20, and the amount of air blown into the blower 30 are controlled substantially in the same manner as described above. Then
The air flow introduced by the blower 30 is cooled by the evaporator 40 in substantially the same manner as described above, and from at least one of the outlet 13 and the outlet 14 via the air mix damper 50, the heater core 60, and the outlet switching damper 70. The air is blown into the vehicle interior at the latest required blow temperature Tao. As a result, the air-conditioning temperature control in the vehicle cabin, which matches the preference amount Tk in step 350, is properly performed.

Thereafter, "NO" is determined in step 250, and if the determination in step 260 is "YES" on the premise that the change control timer is counting time in step 340 (see Time = T4 to T5 in FIG. 5). , The microcomputer 190 determines in step 260a that the previous step 25
Standard new effective temperature S at the time of determination of “YES” at 0
In the comparison between ET * and the standard new effective temperature SET * at the present stage, when the difference between them is equal to or less than the predetermined temperature difference, it is determined to be "NO" based on the determination that the temperature environment is substantially the same, and the same as described above. The processing shifts to the calculation processing in step 350. On the other hand, at the time of determination of “YES” in step 260a, the microcomputer 190 determines that there has been a change in the amount of heat, and determines the relationship between the standard new effective temperature SET * at this stage and the map. The favorite amount Tk is calculated based on Equation 3 with reference to the average value ΔTMA of the change amount of the warm feeling operation.

Thereafter, "YES" in step 260a.
Alternatively, the necessary blowing temperature Tao, the target opening degree SWo, the blowing mode, the introduction mode, and the target blowing amount Q after the step 280 are substantially taken into consideration in consideration of the desired amount Tk in the step 270 or 350 after the determination of “NO”. Is determined similarly. Thereby, "YES" in step 260a.
Alternatively, in step 270 or 350 after the determination of "NO", the control of the air-conditioning temperature in the vehicle compartment that matches the desired amount Tk is properly performed. Further, the above control contents are for the case where the warm feeling switch 90b is operated, but the present invention is not limited to this, and substantially the same control contents are realized when the warm feeling switch 90a is operated.

If it is determined in step 230 that the second or third personal selection signal is generated from the operation panel P, the microcomputer 190 causes the computer program to execute the personal automatic control routine 360 or Proceed to 370. Thus, in the personal automatic control routine 360, the arithmetic processing in the steps subsequent to the above-described step 240 is performed substantially similarly so as to realize the preference of the occupant selecting the personal selection switch 80b for the air conditioning control. In the personal automatic control routine 370, the arithmetic processing in the steps subsequent to the step 240 is performed by the personal selection switch 80c.
Is substantially the same so as to realize the occupant's preference for air conditioning control.

As will be easily understood from the above description, in this embodiment, each of the personal selection switches 80a, 80b and 80c and each of the warming switches 90
a, 90b, and based on the selection operation of any one of the personal selection switches 80a, 80b, and 80c of each occupant and the selection operation of each of the warmth switches 90a, 90b,
By calculating and learning the amount of preference Tk for air conditioning control that matches the preferences of each occupant, and utilizing this learning result effectively to implement air conditioning control in the vehicle cabin, comfortable automatic air conditioning control that meets personal preferences is achieved. , Even if various thermal environmental factors change,
Accurate realization can be achieved without frequent setting change operations for the set temperature in the passenger compartment.

In the practice of the present invention, the method for calculating the thermal sensation is that the standard new effective temperature SET * is used instead of the standard new effective temperature SET *.
A PMV according to the SO standard may be used.

In practicing the present invention, when calculating the preference amount, the average value of the past control change amounts is not used. For example, the past change such as weighting over time or restricting data is performed. Any method can be used as long as the history can be taken as a favorite amount.
