[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air conditioning controller for automatically controlling air conditioning in a vehicle compartment,
The present invention relates to an air conditioning control device for a vehicle that obtains a control characteristic suitable for a passenger's sense of heat.

[0002]

2. Description of the Related Art As a conventional vehicle air-conditioning control device, the set temperature characteristics desired by an occupant are sequentially stored for each outside temperature to estimate a desired room temperature for each season, and the set temperature is corrected according to the desired room temperature. There are some that are controlling the air conditioner. However, even if the outside temperature is the same (season), the thermal sensation felt by the occupant varies greatly depending on the initial room temperature, and the set temperature characteristics also differ. For this reason, even if the set temperature change characteristic is stored with only the outside air temperature as a condition and the air conditioning control value is corrected, it is difficult to accurately match the thermal sensation of the occupant in the indoor thermal environment, which is constantly changing.

In order to solve the above problem, for example, there is a "vehicle air conditioning control device" disclosed in Japanese Patent Application Laid-Open No. 3-54015. In this technique, room temperature is added to the storage condition, the set room temperature information is stored in a region divided by the room temperature and the outside temperature, and the set temperature is corrected (updated) based on the set room temperature information. . The details will be described below.

FIG. 29 is a flow chart showing the operation of the vehicle air conditioning control device. First, initial setting is executed (S10), and the target indoor temperature T _DT is set based on a predetermined process according to the outside air temperature (S11). After that, various detection signals from the vehicle interior temperature sensor and the like were input (S1
2) After that, it is judged whether or not the manual setting of the target room temperature by the manual setting means is executed (S13), and when it is judged that the manual setting is executed, the set room temperature T set by the manual setting means is set. Substituting _D into the target room temperature T _DT ,
The value of the target room temperature T _DT is changed (S14).

Next, the outside air temperature range is determined based on the outside air temperature T _A input in step S122 (S15), and the value of the target room temperature stored value R corresponding to the determined outside air temperature range is determined. The target room temperature stored value is updated by rewriting the set room temperature T _D (S16). After that, the target blowout temperature calculation (S17), the mix door control (S18), the blower control (S19), the compressor control (S20), and the mode control (S21) are executed.
As a result, the occupant's preference of the air conditioning state can be reflected in the automatic control.

[0006]

However, under the condition that the amount which changes momentarily during one use, such as room temperature, is not stored in the entire area at the time immediately after the start of use. In some cases, or when there is an area where operations are rarely performed even after the number of times of use, control stability may be adversely affected. For example, if the initial room temperature is high even if the outside temperature is the same, it will take several areas with different room temperatures until the room temperature becomes stable.

Further, when the area operated by the target occupant is limited and there is an area having no stored information, the set temperature in that area remains at the initial value, and the set temperature has an unexpected pattern. It may fluctuate.

The present invention has been made in view of the above, and not only the seasonal thermal environment condition such as the outside temperature but also the thermal environment condition that fluctuates in a short time such as the room temperature is one condition. The purpose is to store the environment setting characteristics, estimate the target air-conditioning condition, and correct it to match the thermal sensation of the occupant with high accuracy and ensure control stability.

[Control Operation of Air Conditioner] FIG. 3 is a flowchart showing the control operation of the entire air conditioner. That is, when the automatic air conditioner operation switch 35, which is the start switch of the air conditioner 1, is pressed, the values of the predetermined constants A to U and the occupant setting change information used in the calculation of each step described later are stored in the controller 30. The initialization process of reading from the memory built in is executed (S101), and then
An air-mix door for controlling the amount of cold air passing through the heater core after executing the data input processing for reading the output signal of each sensor as the thermal environment information detecting means, the set room temperature of the occupant, and the state of each switch (S102), and passing through the heater core after passing through the evaporator. The opening degree X of is calculated (S103). That is, the target outlet temperature Tof required to reach the set room temperature under the current heat load state is obtained, and the air mix opening X for adjusting the outlet temperature Tof is calculated.

Subsequently, when the target outlet temperature is Tof, the outlet mode processing for determining the optimum outlet mode is executed (S104), and the inlet processing for determining the state of the inlet is executed (S105). Further, the blower fan voltage Vfan is determined by the blower fan applied voltage characteristic that is predetermined so as to blow out the air volume according to the target blowout temperature Tof.
The air volume processing for determining is executed (S106).

Then, the above steps S104 to S106.
The output process of outputting a control signal to each actuator is performed so that the control amount calculated in step S10 is obtained (S10).
7) Then, the process returns to step S102 and the processes of steps S102 to S107 are repeatedly executed until the off switch is pressed. The details of each step will be described below.

The feature of the present invention lies in the calculation of the set room temperature correction amount by reading the data from the set room temperature correction map in the initialization process of step S101 and the set room temperature in the data input process of step S102 in the above flow chart. It is information storage for the correction map.

Initialization Process FIG. 4 shows details of the initialization process shown in FIG.
Here, first, the constants A to F used in the calculation of the target outlet temperature Tof in step S103, the constants F, G, and H used in calculating the air mix opening, and the constants required for determining the outlet mode in step S104. The constants I to L, the constants M to Q required for determining the suction port mode in step S105, and the constants R to U required for determining the blower fan voltage in step S106 are set (S201).

Next, from the set room temperature change storage information stored in the set room temperature correction map of the volatile memory, the set temperature correction amount Tptc, cor [i] [ j] is calculated (S20
2) Return to the main flow. The set room temperature correction map, which is a feature of the present invention, is shown in FIG. 12B for each region divided by the heat load (25 ° C.-room temperature Tic) and the outside air temperature Tamb (° C.) as shown in FIG. As shown in
The set room temperatures for the past N times and their average values are stored. The timing and contents of storage will be described later. Note that Fig. 1
2 (b) j (outside temperature range), i (heat load range)
Indicates the address of the set room temperature correction map.

Next, the processing contents of step S202 will be described with reference to the flowchart shown in FIG. Figure 11
First, the value of the counter for the outside air temperature region is reset to 1 (j = 1) (S901), and subsequently, the correction amount stored in the storage region corresponding to the outside air temperature region j is set in descending order of room temperature. Are read in the order of storage array (S902).
That is, Tptc, mem [i] [j] (i = 1, 2, ..., N
h1). Here, i = 1: When the cooling heat load is large i = 2: When the cooling heat load is slightly large i = 3: Optimal temperature state i = 4: When the heating heat load is slightly large i = 5: The heating heat load is large Each corresponds to a state.

Next, the set room temperature correction amount Tptc, mem
Modify the values of [i] [j] according to the following rule, and
ptc, mem1 [i] [j] (i = 1, 2, ...,
Nh1, j = 1, 2, ..., Namb) (S9)
03). That is, if i = 1, 2 and Tpt
c, mem [i] [j] is Tptc, mem [i +
1] [j], Tptc, mem1 [i]
[J] = Tptc, mem [i + 1] [j], and i = 4,5 and Tptc, mem1 [i]
If [j] is smaller than Tptc, mem1 [i-1] [j], Tptc, mem1 [i] [j] = Tpt
c, mem [i-1] [j], and Tptc, mem
1 [i] [j] = Tptc, mem [i] [j]. Here, “1” of Tptc and mem1 indicates the corrected set room temperature correction amount.

This limits the set temperature so that the set room temperature does not become higher during cooling than in a region where the heat load is small, and similarly limits the correction direction of the set temperature so that it does not become lower during heating. It is a thing. This can prevent the control direction from going backwards.

Then, the value of j is incremented (j = j
+1) (S904), and the value of j is the stored number N of the outside temperature region.
Whether or not amb is exceeded, that is, j <Namb is determined (S905), and when it is determined that it is not exceeded, the above steps S902 to S904 are repeated until the value of j exceeds the stored number Namb of the outside air temperature region. . Conversely,
When it is determined that the value of j exceeds the number of storages Namb in the outside air temperature region, next, Tptc, mem1 [i]
[J] (i = 1, 2, ..., Nh1, j = 1, 2, ...
······································
2, ..., Nh1, j = 1, 2, ..., Namb)
(S906).

That is, if j = 0, then Tpt
c, cor [i] [j] = (1−W1) · Tptc, m
em1 [i] [j] + W1 · Tptc, mem1 [i]
[J + 1], and if j = Namb, then Tp
tc, cor [i] [j] = (1−W1) · Tptc,
mem1 [i] [j] + W1 · Tptc, mem1
[I] [j-1], and if 1 <j <Namb, then Tptc, cor [i] [j] = (1-2.W
1) .Tptc, mem1 [i] [j] + W1. (Tp
tc, mem1 [i] [j-1] + Tptc, mem1
[I] [j + 1]).

Here, W1 is the degree of influence exerted by the adjacent outside air temperature region data, and is a predetermined value satisfying 0 <W1 <1. After that, Tptc, mem1
[I] [j] (i = 1, 2, ..., Nh1, j = 1,
2, ..., Namb) for the outside air temperature region is judged whether or not the values smoothed by the above-mentioned regulation are inconsistent (S9).
07), if it is determined that there is a contradiction, the previous value is used (S908). On the other hand, if it is determined that there is no contradiction, the process returns to step S202 and returns to the main flow.

As described above, the stored manual setting characteristic is not used as it is, but when the setting characteristic inconsistent as the control direction is stored, the interpolation is performed by using another setting characteristic. ， Control stability can be secured.

Data Input Processing FIG. 5 shows details of the data input processing shown in FIG. Here, the input signal from each sensor and the setting state of the manual setting switch are input and set to the corresponding variables.

That is, the detected room temperature is Tic, the detected outside air temperature is Tamb, the detected solar radiation amount is Qsun, the passenger set room temperature is Tptc, and the manually set blower fan voltage set value is Vfa.
Each of them is set to n and m, and the selected states of the outlet mode switch and the inlet switch are input (S301).

Next, it is judged whether or not the set room temperature Tptc has been changed (S302). When it is judged that the change has been made, then, after a sufficient time has passed since the change, the setting becomes a constant value. If it is determined that the setting has fallen to a certain value (S303), and if it is determined that the setting has fallen to a certain value, the change information of the setting room temperature is changed to the heat load of the setting room temperature correction map shown in FIG. And an area corresponding to the outside temperature are stored (S304).

As shown in FIG. 12A, the set room temperature correction map is shown in FIG. 12 for each area divided by the heat load (25 ° C.-room temperature Tic) and the outside air temperature (Tamb).
As shown in (b), the set temperature of past N times and the average value thereof are stored. The number of set room temperatures to be stored is limited to a preset value, and when the number of times is changed more than once in the same area, the oldest setting is successively replaced so that the latest information can always be stored.

Further, as the average value here, the arithmetic average value of all the stored set temperatures is used, but a weighted average value in which a newer one is weighted more may be used. If such a weighted average value is used, it becomes possible to store the set room temperature closer to the recent setting, and the new setting can be reproduced in the memory of the operator.

Further, the median value may be used instead of the average value. That is, it is the value located at the center when the stored data are arranged in order of size. The effect of using the median value is that when a large (or small) data is suddenly stored compared to other data, the adverse effect of the data can be eliminated and a stable representative value can be obtained. It is in.

Air Mix Door Processing FIG. 6 shows details of the air mix opening processing shown in FIG. First, from the current room temperature Tic and the outside temperature Tamb, it is determined which storage area i, j corresponds to on the room temperature correction map shown in FIG. 11A, and the set room temperature correction amount Tpt is set.
Tp obtained in the above step S202 for c and cor
tc, cor [i] [j] are set (S401).

Next, the value of the set room temperature is corrected by the following equation (S402). That is, Tptc '= Tptc + Tptc, cor. After that, the value of the target outlet temperature Tof is calculated by the following formula (S403. That is, Tof = A * Tptc '+ B * Tamb + C * Qsun).
+ D × Tic + E. Next, the air mix opening X is calculated by the following formula (S404). That is, X = F × Tof ² + G × Tof + H is calculated.

Blow-Out Mode Processing FIG. 7 shows details of the blow-out mode processing shown in FIG. First, an outlet is selected using a predetermined outlet mode map according to the target outlet temperature Tof (S
501). Here, the balloon states in each mode are shown below. Vent mode: blows out only from the ventilator grill located on the instrument panel. Bi-level mode: blow out from both the ventilator grille and the foot outlet. Foot mode: Open at the foot outlet and the upper surface of the instrument, and blow out to the inside of the front window from the defroster outlet.

Next, it is judged whether or not the air outlet mode switch 41 is pressed (S502). If it is judged that the air outlet mode switch 41 is pressed, the vent mode (S503), the bi-level mode (S504), the foot In the mode (S505) and the defroster mode (S506), an outlet mode corresponding to each is selected.

Suction Port Processing FIG. 8 shows details of the suction port processing shown in FIG.
First, the state of the suction port is selected using a predetermined suction port map according to the target outlet temperature Tof (S60).
1). Here, each state is REC: 100% 20% FRE: 20% outside air introduction, 80% inside air circulation FRE: 100% outside air introduction.

Next, it is judged whether or not the suction port switch is pressed (S602), and if it is judged that it is pressed, it corresponds to outside air introduction (S603) and inside air circulation (S604). Select the suction port to use.

Air Volume Processing FIG. 9 shows details of the air volume processing shown in FIG. First, the blower fan applied voltage Vfan is selected using a predetermined blower fan applied voltage map according to the target blowout temperature Tof (S701). Next, it is determined whether or not the blower fan voltage setting switch is pressed (S7
02), when it is determined that the blower fan motor is pressed, the output value Vfan 'to the blower fan motor is set to the selected voltage Vf.
On the other hand, when it is determined that the button is not pressed, Vfan 'is set to the above step S7.
The blower fan voltage Vfan determined in 01 is set (S704).

Output Processing FIG. 10 shows details of the output processing shown in FIG.
First, a drive signal is sent to each actuator of the air mix door, the air outlet mode door, and the air inlet mode door so that the air mix opening X, the air outlet mode, and the air inlet are set in steps S103 to 105. It is output (S801). Next, a drive signal is output to the blower fan motor so that the blower fan voltage Vfan 'set in step S106 is obtained (S80).
2).

[Embodiment 2] [Change of smoothing weight depending on the number of setting change information stored] Next, a second embodiment will be described. Step S2 above
Another embodiment of the correction processing of the set room temperature correction map shown in 02 will be described with reference to the flowchart of FIG. First, the average value Tptc, m of the set room temperature correction map
em [i] [j] and the number of set room temperature change information Num
[I] [j] (i = 1, 2, ... Nh1, j = 1,
2, ..., Namb) are read (S1001).

Next, the counter j in the outside air temperature region is set to 1 (j = 1) (S1002), and the counter i in the heat load region is set to 2 (i = 2) (S1003). Thereafter, it is determined whether Num [i] [j] exceeds Num0 or Num [3] [j] + Num1 (S1004). That is, it is determined whether or not Num [i] [j]> Num0 Num [i] [j]> Num [3] [j] + Num1 is satisfied. Correction value Tptc, mem [i]
Correcting the value of [j], Tptc, mem1 [i]
It is set to [j] (S1005).

In step S1005 described above, the number of stored set room temperature change information is small, and the reliability of the data is lacking. Therefore, the same restrictions as those in the first embodiment are set in the control contradictory direction. . That is, if Tptc,
mem [i] [j]> Tptc, mem [i + 1]
If [j], Tptc, mem1 [i] [j] = T
ptc, mem [i + 1] [j], and Tptc, m
em1 [i] [j] = Tptc, mem [i] [j], and is forcibly adjusted to the value on the smaller heat load side.

On the contrary, when it is determined that the above equation is not satisfied, the set room temperature correction values Tptc, mem [i] [j] are set.
The value of is corrected (S1006). Step S1006
In this case, since the number of memories is large and it can be judged as the characteristic of the operator, even if the stored data is in a controlly contradictory direction, the weight is loaded with the characteristic at the time of stability as a reference to take in the correction value. That is, if T
ptc, mem [i] [j]> Tptc, mem [i +
1] [j], Tptc, mem1 [i] [j]
= Tptc, mem [i] [j]. (Num [i]
[J], (Num [i] [j] + Num [3]
[J])) + Tptc, mem [3] [j] [Num
[3] [j], (Num [i] [j] + Num [3]
[J])], and Tptc, mem1 [i] [j] =
Tptc, mem [i] [j].

Further, the counter i in the heat load area is decremented (i = i-1) (S1007), and i <
It is determined whether 1 is satisfied (S1008). Here, in the determination, the processes of steps S1004 to S1007 are repeated until i becomes smaller than 1.

Next, the process shifts to the flowchart of FIG. In FIG. 14, steps S1009 to S1014
Each of the steps indicates the correction processing on the heating side. First, when it is determined in step S1008 that i <1 is satisfied, then the set value of i is set to 4 (i = 4) (S1009). ), And then Num [i] [j] is Num
0 or Num [3] [j] + N
It is determined whether or not um1 is exceeded (S1010).
That is, it is determined whether or not Num [i] [j]> Num0 Num [i] [j]> Num [3] [j] + Num1 is satisfied. Correction amount Tptc, mem [i]
[J] is corrected (S1011). That is, if T
ptc, mem [i] [j] <Tptc, mem [i-
1] [j], Tptc, mem1 [i] [j]
= Tptc, mem [i-1] [j], and Tpt
c, mem1 [i] [j] = Tptc, mem [i]
[J].

On the contrary, if it is determined in step S1010 that the above equation is satisfied, the set room temperature correction amounts Tptc, mem [i] [j] are corrected (S10).
12). That is, temporarily, Tptc, mem [i]
If [j] <Tptc, mem [i-1] [j],
Tptc, mem1 [i] [j] = Tptc, mem
[I] [j]. (Num [i] [j], (Num [i]
[J] + Num [3] [j])) + Tptc, mem
[3] [j]. (Num [3] [j], (Num [i]
[J] + Num [3] [j])), and Tptc, m
em1 [i] [j] = Tptc, mem [i] [j].

After that, i is incremented (i = i +
1) (S1013), and then it is determined whether i> 5 is satisfied (S1014). As a result, if it is determined that i> 5 is not established, the process returns to step S1010, and conversely, if it is determined that i> 5 is established,
The value of the set room temperature correction amount Tptc, mem1 [3] [j] is set to Tptc, mem [3] [j] (S101).
5). That is, Tptc, mem1 [3] [j] = T
ptc, mem [3] [j].

Thereafter, the counter j in the outside air temperature region is incremented (j = j + 1) (S1016), and then it is determined whether or not j is larger than Namb (S1017).
That is, it is determined whether or not j> Namb, and the above steps S1003 to S1016 are repeated until j is determined to exceed Namb. If it is determined that j> Namb, Tptc, The smoothing process of mem1 [i] [j] is performed on the outside air temperature region to obtain Tptc, cor [i].
[J] is determined (S1018).

As described above, by adopting the above-mentioned configuration, in the case where the same change is always repeated even if the control is contradictory, the operation is conditionally added, whereby The air conditioner can be controlled by a setting pattern that is closer to the operating characteristics of the occupant.

[Third Embodiment] [Correction process using membership function of fuzzy theory,
Setting Correction] Next, a third embodiment will be described. First, the processing in this embodiment of step S202 (reading of data from the set room temperature correction map in the initialization processing) shown in FIG. 4 will be described based on the flowchart shown in FIG.

From the set room temperature correction map, the average value Tptc,
mem [i] [j] and the number of set room temperature change information Num
[I] [j] (i = 1, 2, ... Nh1, j = 1,
2, ..., Namb) are read (S1101). Next, the counter j in the outside air temperature region is set to 1 (j = 1) (S1102), and the counter i in the heat load region is set to 1 (i = 1) (S1103).

After that, the number of memories Num when stable
[3] [j] and Num [i] currently being processed
From [j], the weight W used in the subsequent step
Is obtained according to a rule based on the fuzzy theory shown below (S1104). The rule used here is: Num [i] [j] = A and Num [3]
[J] = B then W = C, where A = {ZO, MI, BG} B = {ZO, MI, BG} C = {ZO, MI, BG} (where ZO, MI, BG are Show fuzzy variables of membership function), rule table of this rule and A,
The membership functions of the fuzzy variables ZO, MI, and BG of B and C are shown in FIGS. 16 and 17, respectively. As shown in FIG. 16, the number of rules Nr is 9, and the weight W inferred by the MAX-min method for each of these rules is W.
[K] (k = 1, 2, ..., 9) is fuzzy by the centroid method to determine W.

Next, using the obtained weight W and the stored data Tptc, mem [3] [j] in the stable state, Tp
The values of tc, mem [i] [j] are corrected by the following equation, and Tpt
c, mem [i] [j]. That is, Tptc, mem1 [i] [j] = W [i] .Tpt
c, mem [i] [j] + (1-W [i]). Tpt
Using c, mem [3] [j], the set room temperature correction amount of the storage area i is determined (S
1105).

As shown in the rule table of FIG. 16, in the present embodiment, even if the number of storages Num [i] [j] stored in the room temperature storage area currently being processed is large, the stable area The rule is determined so that the weight is slightly reduced when the number of memory of is large, and the center of MI of the membership function of the fuzzy variable C is set to a side smaller than 0.5. As a result, the weight of the stored data in the stable region is increased as a whole, and the set room temperature is corrected mainly based on the stored data in the stable region while the number of times of storage in the regions other than the stable region is small.

Next, the counter i in the heat load area is incremented (i = i + 1) (S1106), and then i> 5.
It is determined whether or not (S1107). Step S1107
In, the processing of steps S1104 to S1106 is repeated until it is determined that i exceeds 5 (Nh1). If it is determined that i> 5 is satisfied, the counter j in the outside air temperature region is incremented (j = j + 1) (S1108), and then it is determined whether or not j> Namb (S1109). In step S1109, j is N
The above step S110 until it is determined that the value exceeds amb.
The processes of 1 to S1108 are repeated. Also, Tptc, m
The values of em1 [i] [j] are smoothed to the outside air temperature region and Tp
Set to tc, cor [i] [j] (S1110)
After that, return to the main flow.

[Fuzzification of Judgment of Heat Load 25 ° C.-Tic] Next, in step S 401 (determining the set room temperature correction amount by judging the storage area to which the current outside temperature and room temperature belong) shown in FIG. Another embodiment will be described with reference to the flowchart shown in FIG.

First, from the current room temperature Tic, the region belonging degree ω [k] (k = 1, 2, ...
..Nh1) is determined by the rule and membership function shown in FIG. 19 (S1201). Then, based on the obtained ω [k], the value of Tptc, cor is calculated by the following formula 1
Then, the process returns to the main flow (S1202).

[0078]

[Equation 1]

As described above, the characteristic of changing the set room temperature, which is stored stepwise in each heat load region, can be continuously set according to the change of the room temperature. Therefore, there is an effect that the control does not change suddenly and becomes smooth.

[Fourth Embodiment] Next, a fourth embodiment will be described. The fourth embodiment is an application of the above embodiment to the manual operation of the air volume. Hereinafter, only the characteristic part will be described in detail for each process.

Initialization Processing Initialization processing will be described with reference to the flowchart of FIG. Steps S1301 and S1302 are respectively shown in FIG.
Since it is the same as steps S201 and S202 shown in FIG. After the process of step S1302 is finished, the air volume correction amount Vfan, mem [i] [j] under each thermal environment when the air conditioner is used this time is determined from the air volume change information stored in the air volume correction map of the volatile memory. And the number of data stored in the air volume correction map Num, f
An [i] [j] is read (S1303), and the process returns to the main flow.

The air volume correction map is the same as the set room temperature correction map shown in FIG.
For each area divided by 5 ° C.-Tic and Tamb, the past N times the air volume change value and the average value that is the representative value thereof are stored (see FIG. 11B).

Data Input Processing Data input processing will be described with reference to the flowchart of FIG. Steps S1401 to S1404 are the same as steps S301 to S304 shown in FIG. 4, respectively, and description thereof will be omitted. After the processing of step S1404 is finished, it is determined whether or not the blower fan voltage is manually set (S1405). If it is determined that the blower fan voltage has been manually set, then it is sufficient time to start changing the blower fan setting voltage. And the blower fan setting has fallen to a fixed value, that is, whether or not the change of the blower fan voltage has converged (S1406).

As a result, when it is determined that the blower fan voltage has converged, the change information of the blower fan voltage is stored in the area corresponding to the present room temperature and outside air temperature of the air volume correction map shown in FIG. The air volume change information to be stored stores the difference between the blower fan voltage setting value Vfan (determined in step S1501 in FIG. 22) and the setting voltage Vfan, m manually set at the time of automatic control, and is representative. As the value, an average value with the already stored fan voltage change value is calculated and stored (S1407). The number of air volume change information to be stored is limited to a predetermined value N, and when the number of times of change is N or more in the same area, the oldest set value is sequentially replaced so that the latest information can always be stored. is there. Also in this case, as in the first embodiment, the average value as the representative value may be a weighted average value in which the weight is increased for the latest data, or the median value may be used.

Air Volume Processing The air volume processing will be described with reference to the flowchart of FIG. First, similarly to step S701 shown in FIG. 8, the blower fan applied voltage Vfan at the time of automatic control is calculated according to the target outlet temperature Tof at that time (S150).
1), the storage areas of the air volume correction maps corresponding to the current room temperature Tic and the outside air temperature Tamb are set to i and j, respectively (S1502). After that, the corrected blower fan voltage Vfa
The correction amount Vfan, cor of n is calculated (S1503),
It is determined whether or not the blower fan voltage setting switch is pressed (S1504).

If it is determined that the blower fan voltage setting switch is pressed, Vfan, m is set to the blower fan output value Vfan ^' (S150).
5). On the contrary, if it is judged that the button has not been pressed, V
After setting fan and cor to the blower fan output value Vfan ^' (S1506), the process returns to the main flow.

[Method of Calculating the Value of Vfan, cor] Next, the method of calculating the value of the corrected blower fan voltage Vfan, cor in step S1503 will be described with reference to the flowchart of FIG. First, it is determined whether or not i <3 (cooling unsteady state, room temperature / high temperature side) (S1601), i <3 (cooling unsteady state,
If it is determined that it is not the room temperature / high temperature side), then it is determined whether i> 3 (heating unsteady, room temperature / low temperature side) (S1602).

In step S1601, i <3
When it is determined that the cooling load is unsteady, the room temperature and high temperature side, the air volume change information Vfan, mem [i] [j] included in the target storage area i, j and the one having the lower heat load are displayed. The air volume change information Vfan, mem [i + 1] [j] is read, and the corrected air volume Vfan, cor [i] is read.
[J], Vfan, cor [i + 1] [j] are calculated based on the following equation (S1603). That is, Vfan, cor [I] [j] = Vfan + Vfa
n, mem [I] [j] Vfan, cor [I + 1] [j] = Vfan, pr
ed + Vfan, mem [I + 1] [j].

However, Vfan, pred is a blower fan voltage obtained assuming that the room temperature is the room temperature corresponding to the heat load storage area i + 1 in the current thermal environment.
It is obtained using Tof and pred calculated by the following equation. That is, Tof, pred = A × Tptc ′ + B × Tamb + C
× Qsun + D × Tic, c [i + 1] + E where Tic, c [i] (i = 1 or 2) is as shown in FIG.
In the characteristic map shown in (a), it is the lower boundary temperature of each heat load storage area i, and in this embodiment, Tic, c [2] = Tptc ′ + 8 Tic [3] = Tptc ′ + 3. .

Next, Vfan, cor [i] [j] and Vfan, co obtained in step S1603 are obtained.
It is compared with r [i + 1] [j] (S1604). That is, Vfan, cor [i] [j] <Vfan, cor [i
+1] [j] and Vfan, cor [i] [j] <Vfa
If n, cor [i + 1] [j] holds, Vfan, cor [i] [j] is corrected by the following equation (S)
1605). That is, Vfan, cor [i] [j] ← Vfan, cor [i
+1] [j].

That is, the fact that the process has shifted to this step means that the air volume characteristic is stored so that the air volume becomes smaller than that on the side where the heat load is small, so that the air volume characteristic is adjusted to the side where the heat load is small. By doing so, the feeling of discomfort is eliminated.

Steps S1606 to S1608 correspond to the contents of steps S1603 to S1605, and although the contents of each step are the same, the directions of the heat load storage areas to be compared are opposite. That is, the above step S1602
When it is determined that i> 3 (heating unsteady, room temperature low temperature side), the air volume change information Vfan, mem [i] [j] included in the target storage area i, j and one heat Air volume change information Vfan, mem [i-
1] [j] is read, and the correction air volume Vfan,
cor [i] [j], Vfan, cor [i-1]
[J] is calculated by the following equation (S1606). That is, Vfan, cor [i] [j] = Vfan + Vfan,
mem [i] [j] Vfan, cor [i-1] [j] = Vfan, pre
d + Vfan, mem [i-1] [j].

However, similar to the processing of step S1603, Vfan and pred are obtained on the assumption that the room temperature has reached the room temperature corresponding to the storage area i-1 with a lower heat load while maintaining the current heat environment. The fan voltage, which is calculated using Tof and pred calculated by the following equation. That is, Tof, pred = A × Tptc ′ + B × Tamb + C
XQsun + DxTic, w [i-j] + E where Tic, w [i] (i = 4or3) is as shown in FIG.
In the characteristic map of (a), it is the boundary temperature on the high side of each heat load storage area i, and in this embodiment, Tic, c [4] = Tptc'-8 Tic [3] = Tptc'-3.

V obtained in the above step S1606
fan, cor [i] [j] and Vfan, cor [i-
1] [j] is compared. That is, Vfan, cor [i] [j] <Vfan, cor [i
−1] [j] and Vfan, cor [i] [j] <Vfa
When n, cor [i-1] [j] is satisfied, Vfan, cor [i] [j] is corrected by the following equation (S1).
608). That is, Vfan, cor [i] [j] ← Vfan, cor [i
-1] [j].

That is, the fact that the flow has moved to this step means that the air volume characteristic is stored so that the air volume becomes smaller than that on the side where the heat load is small, so the air volume characteristic is adjusted to the side where the heat load is small. This will eliminate discomfort.

In the above step S1602, i> 3
If it is determined that it is not (heating unsteady, room temperature / low temperature side), the heat load storage area is i = 3 (when room temperature is stable), so V
Vfan, mem [i] to fan, cor [i] [j]
The value of [j] is set as it is (S1609). That is, Vfan, cor [i] [j] ← Vfan, mem
Let [i] and [j].

Then, Vfan of the current heat load area i,
Cor [i] [j] is set as Vfan, cor (S1610). That is, Vfan, cor [i] [j] = Vfan, cor is set and the process returns to the main routine.

Next, another example of the method of calculating the correction amount Vfan, cor will be described with reference to the flowcharts of FIGS. First, it is determined whether or not the air conditioner has just been started or whether the outside temperature storage area j has been changed (S1701),
Immediately after the air conditioner is started, or when it is determined that the outside temperature storage area j has been changed, it is then determined whether i <3 (cooling unsteady state, room temperature / high temperature side) (S1702). As a result, i <3
(Unsteady cooling, room temperature / high temperature side), the Num of the outside air temperature storage area j currently being targeted is determined.
[K] [j] (k = 1, 2, 3) with a default value Num0
The air flow rate correction flag Flg [k] in the heat load region i exceeding Num0 is set to 1 and is set to 0 if Num0 is not exceeded (S1704).

After that, Flg [k] (k = 1, 2, 3)
The value of Vfan, mem [k] [j] is corrected by
fan, mem1 [k] [j] (S1705).
That is, Vfan, mem 1 [k] [j] = Flg [k] · V
fan, mem [K] [j] (k = 1, 2, 3), and the reliability of the change information is considered to be low for the storage area k in which the number of storages is equal to or less than the default value Num0, V
The value of fan, mem1 [k] [j] is set to 0.

In step S1702,
When it is determined that i <3 (cooling non-steady state, room temperature / high temperature side), it is next determined whether i> 3 (heating non-steady state, room temperature / low temperature side) (S1703), i> If it is determined to be 3 (heating unsteady, room temperature / low temperature side), Num [i] [j] (i = 3) of the outside air temperature storage area j currently being targeted is determined, as in step S1704. , 4,
The air flow rate correction flag Flg [i] of the heat load region i exceeding the predetermined value Num0 by the value of 5) is set to 1 and is set to 0 when it does not exceed Num0 (S1706).

After that, as in the processing of step S1705, Vfa is set by Flg [k] (k = 3, 4, 5).
n, mem [k] [j] are corrected, Vfan, mem1
[K] [j] (S1707). That is, Vfan, mem1 [k] [j] = Flg [k] · Vf
an, mem [K] [j] (k = 3,4,5).

In step S1703, i> 3
If it is determined that the temperature is not (heating unsteady, room temperature / low temperature side), then Vfan, mem1 [i] [j] becomes Vfan, me because the heat load storage area is i = 3 (at room temperature stable).
The values of m [i] [j] are set as they are (S170).
8). That is, Vfan, mem1 [3] [j] = Vfan, mem
[3] [j]

24 and 25, steps S1709 to S1.
At 718, the same processing as steps S1601 to S1610 of the flowchart shown in FIG.
Vfan, mem instead of an, mem [i] [j]
1 [i] [j], Vfan, cor
[I] [j] is calculated to determine Vfan, cor, and the process returns to the main flow.

[Heat load 25 ° C.-T for stabilizing control
The determination of ic is made fuzzy] Next, another embodiment of Vfan, cor in step S1503 shown in FIG.
A description will be given based on the flowchart. First, the value of the modified blower fan voltage Vfan, cor [i] [j] corresponding to the outside temperature storage area j to which the current thermal environment belongs is shown in FIG.
3, calculated using the method of the flowchart of FIG.
However, Vfan, cor [i] [j] to be set is
The value of the heat load storage area i is limited to the range up to i = 3 when the air conditioner is started, and 0 is set to other Vfan, cor [i] [j] (S1801).

Next, from the current room temperature Tic, the region membership degree ω [k] for determining the region of heat load is determined by the rule and membership function shown in FIG. 19 (S1).
802). Then, based on the obtained ω [k], Vfa
The values of n and cor are determined by the equation 2, and the process returns to the main flow.

[0106]

[Equation 2]

By controlling in this way, the characteristics of the air volume change stored stepwise in each heat load region can be continuously set according to the change of the room temperature. Therefore, the control of the air volume is smooth without sudden changes.

[Other Application Examples] In the above-described embodiment, the heat load (2
5 ° C-room temperature Tic) and outside temperature Tamb are used,
Other application examples for achieving the object of the present invention are as follows. All of these have the same effect only by replacing the heat load and the outside air temperature in this embodiment. That is, firstly, as another example of the heat load (25 ° C.-room temperature Tic), Tptc-Tic room temperature Tic comprehensive heat load index al · (Tptc-Tic) + a2 · Tamb + a3 ·
Qsun + a4 ・ Hic + a5 ・ Qint + a6 (Hic: relative humidity in the passenger compartment, Qint: radiant heat from interior parts) The comfort index such as effective temperature ET and PMV is used.

Secondly, as another example of the outside air temperature Tamb, a total value season (calendar) in which the outside air temperature Tamb is added to the outside air relative humidity Hex, the amount of solar radiation Qsun, and the vehicle speed Vcar is used.

In the above embodiment, the combination of the total outside air temperature and the total heat load shown in FIG. 12 (a) can be stored as the correction map. When it is high, there is almost no case where the room temperature is lower than the set temperature, so it is possible to reduce the number of regions as shown in FIG. 28 or use it as a steady region.

Further, in the above-mentioned embodiment, the air conditioner for a vehicle having a minimum required number of constituent elements is applied. However, it is equipped with an auxiliary heater, an auxiliary cooler, and a dehumidifier lamp, and Even for those whose ability can be controlled by setting the occupant, the room temperature setting information of this embodiment, the heat load setting information of these auxiliary devices, and the load of the controlled object (for example, in the case of a dehumidifier, the target humidity and the current humidity The same effect can be obtained simply by replacing the difference.

[0112]

As described above, in the device according to the first aspect, the change information when the heat load condition is changed by the manual setting means is changed according to the thermal environment condition inside and outside the vehicle. When the amount of specific manual setting information stored in the divided storage area and stored in the storage area corresponding to the current thermal environment condition is small,
Or when the manual setting information that is inconsistent with the specific manual setting information in the storage area adjacent is stored, by calculating estimates a correction amount for a particular manual setting information, controls the air conditioner by the operation result Therefore, not only the seasonal thermal environment conditions such as the outside temperature, but also the thermal environment conditions that fluctuate in a short time such as room temperature are stored as one condition, and the environment setting characteristics are stored.
