2. Description of the Related Art As a conventional vehicle air conditioner, there is a "vehicle air conditioner controller" disclosed in Japanese Patent Application Laid-Open No. 3-54015. As shown in FIG. 27, the operation of the vehicle air-conditioning control device is performed, after the initial setting (S10) is executed, by a detection signal from a temperature sensor or the like, or by a temperature or air volume setting operation via an operation unit. A signal is input (S11), and a target outlet temperature of air blown into the vehicle interior is calculated based on the input signal (S1).

This is because the operation of the occupant at the set room temperature increases the airflow to bring the room temperature in the cabin closer to the set room temperature as quickly as possible, and the airflow is changed regardless of the occupant's preference and operation. Because it was. As a result, there has been a problem that the occupant may feel uncomfortable in the control reaction corresponding to the operation.

[0004] The present invention has been made in view of the above, and provides a dead zone between the temperature setting and the air volume setting to realize an operation with less discomfort for the occupant in a control reaction corresponding to the operation. Aim.

Further, in the air conditioner according to claim 6, the air conditioning control means CL6 operates one of the temperature setting means CL4 and the air flow setting means CL5 by the operation frequency detecting means CL7. Based on the difference between the frequency and the number of times both are operated within a predetermined time, the amount of the dead zone control is controlled to be smaller as the frequency or the number of times both are operated is larger.

Further, in the air conditioner according to claim 7, the air conditioning control means CL6 controls the amount of the temperature dead zone or the airflow dead zone based on a signal from the thermal environment detecting means CL3.

In the air conditioner according to the present invention, the air conditioning control means CL6 divides the thermal environment into a plurality of conditions based on a signal from the thermal environment detecting means CL3, and separates the thermal environment for each of the conditions. The amount of the dead zone or the airflow dead zone is individually calculated.

According to a ninth aspect of the present invention, in the air conditioner, the air conditioning control means CL6 sets an amount of a temperature dead zone and an airflow correction amount in accordance with a temperature set amount by the temperature setting means CL4. The amount of the airflow dead zone and the temperature correction amount are set in accordance with the airflow set amount according to the above, both the operation of the temperature setting means CL4 and the airflow setting means CL5 are performed, and the amount of operation by the temperature setting means CL4 is outside the temperature deadband.

In the air conditioner according to the eleventh aspect, the temperature setting means CL4 or the airflow setting means CL5 sets the current control target temperature or the airflow to increase or decrease.

[0017]

In the air conditioner according to the present invention, there is provided an association between the temperature setting means and the air flow setting means, wherein the operation of one means is corrected for the operation of the other means. In addition to providing a dead zone where each operation amount is within the predetermined range, control is performed so that only the target operation is performed and the other means is not operated if the operation amount is within the predetermined range. In addition, the sense of discomfort to the control reaction of the executed operation is reduced.

Further, in the air conditioner according to the present invention (claim 2), the width of the dead zone in which there is no operational association is automatically controlled to an appropriate range.
Depending on whether the operation of the temperature setting means and the airflow setting means has been performed substantially simultaneously or whether only one of them has been performed, if the operation of both means is performed, the width of the dead zone is gradually increased. So that the correction of the other means can be automatically performed only by operating one of the means, so that the occupant can correct the other means by operating only one of the means. Can be reduced. If only one operation is performed, the width of the dead zone is gradually widened to increase the area in which the operation of only one unit does not correct the other unit. Even when the amount is relatively large, the other means is not corrected, so that the control response to the operation performed by the occupant is less uncomfortable.

Further, in the air conditioner according to the present invention (claim 3), the non-operating time for both use and the non-operating time for single use are calculated and integrated, and the width of the dead zone increases as the both non-operating time becomes longer. Since the time has been reduced, the time from one operation to the next operation is regarded as the time satisfied by the operation, and the width of the dead zone is controlled in accordance with the satisfaction time when both are used and the time when used alone.

Further, in the air conditioner according to the present invention (claim 4), the correction direction of the temperature setting means when the airflow setting means is operated is set with respect to a target heat environment such as a room temperature deviation. Hot or cold,
Since the correction direction is changed, for example, in the winter, when the passenger has just boarded and the room temperature is low, if the occupant performs control to increase the airflow, the correction of the temperature setting means is corrected in a direction to warm up more, so that the occupant can be corrected. To accurately match the warm / cool, wind speed sensation.

In the air conditioner according to the present invention (claim 5), when both the temperature setting means and the air flow setting means are performed almost simultaneously, one operation corrects the other means. Instead, the settings made by operating the respective means were used as they were, so if the automatic control did not match the occupant's warmth / cooling, the sense of wind speed, the occupant could freely set the temperature and wind speed, Even if an association is provided, a degree of freedom of setting is provided in a case where it does not match the occupant's feeling.

In the air conditioner according to the present invention, the temperature setting means and the air flow setting means may include:
The frequency or the number of times only one of the means is operated is compared with the frequency or the number of times both are operated within a predetermined time, and the larger the frequency or the number of times both are operated, the smaller the dead zone width is, and the more optimal the dead zone is. Control the width.

In the air conditioner according to the present invention (claim 7), the width of the dead zone is changed according to the thermal environment. For example, in the case of an unpleasant thermal environment, the air conditioner is used as an air conditioner. In many cases, cooling and heating are operated at the maximum capacity in terms of calorific value, and the airflow is often the maximum airflow or an airflow close to the maximum airflow, so even if the width of the dead zone is narrowed, the temperature and There is no room for airflow correction. Therefore, the width of the dead zone is increased in a thermal environment far from the comfortable thermal environment.

In the air conditioner according to the present invention (claim 8), the width of the temperature dead zone or the airflow dead zone is individually stored for each thermal environment. If it is close to, narrow the dead zone width,
An optimum dead zone width is set according to each thermal environment, such as widening the dead zone when the vehicle is far from a comfortable thermal environment.

In the air conditioner according to the present invention, the temperature setting means and the airflow setting means are operated together, and the temperature dead zone and the airflow are adjusted according to the target temperature adjustment amount and the airflow adjustment amount. Adjust the width of the dead zone, for example,
The target temperature adjustment amount is a predetermined amount, and the airflow adjustment amount is determined accordingly.In this case, the airflow set amount has already been set, and therefore, a corrected airflow obtained by adding the airflow adjustment amount to the current airflow. The airflow setting is compared with the set airflow setting.If the airflow setting is larger than the corrected airflow, the occupant determines that a larger airflow adjustment amount is desired, and the width of the temperature dead zone is made smaller, and the airflow adjustment amount is reduced. To be greater than the current value. The same applies to the amount of temperature adjustment.If the set temperature is higher than the correction temperature, the width of the airflow dead zone is made smaller if the direction of heating the vehicle interior thermal environment is higher, and conversely, the vehicle interior thermal environment If the set temperature is lower than the corrected temperature, the width of the airflow dead zone is made smaller.

An air conditioner according to the present invention (Claim 1)
In 0), a minimum / maximum width is provided in each dead zone, and if it is within the minimum / maximum range, the width of the dead zone is adjusted, but only within the minimum / maximum range, for example,
By adjusting the ratio of airflow correction to the amount of temperature adjustment,
The width of the dead zone will not be zero or close to zero. Further, since the width of the dead zone does not take a value larger than an appropriate range, for example, the airflow correction is extremely small for a large value of the temperature adjustment amount, and the airflow correction does not substantially work. .

An air conditioner according to the present invention (Claim 1)
In the case of 1), for example, an operation system that does not specifically set the target temperature in the vehicle interior but adopts an increase / decrease setting of the target value with respect to the current target value is adopted. The occupant can perform a more intuitive input operation than the numerical value of the temperature.

[Control Operation of Air Conditioner] FIG. 5 is a flowchart showing the control operation of the entire air conditioner. That is, when the auto air conditioner operation switch 35, which is the start switch of the air conditioner 1, is pressed, predetermined constants A to U used for the calculation of each step described later are set.
The initialization process of reading the value of the occupant and the setting change information of the occupant from the nonvolatile memory and the volatile memory built in the controller 30 is executed (S100), and then the output of each sensor as the thermal environment information detecting means is executed. A data input process for reading a signal, a set room temperature of the occupant, and the state of each switch is executed (S101), and an air mix opening process for obtaining an opening X of an air mix door for controlling the amount of cold air passing through the heater core after passing through the evaporator.

Subsequently, an outlet mode process for determining an optimal outlet mode when the target outlet temperature is Tof is executed (S
103) Then, a thermal sensation / wind sensation reporting process is executed (S103).
104). Further, a manual switch process and an output process are executed (S105), and the process returns to the step S101.
The processing of S105 is repeatedly executed. Hereinafter, details of each step will be described.

FIG. 6 is a flowchart showing details of the initialization process. Here, an initial setting of constants used in the control flowchart is performed (S200). That is, the constants A to H, P, and Q used in the calculation below.

Air Mix Opening Process FIG. 8 is a flowchart showing details of the air mix opening process. Here, first, the target outlet temperature Tof is calculated from the outside air temperature, the room temperature, the corrected set room temperature, and the amount of solar radiation (S400). That is, Tof = A × Tam + B × Tic + C × Tptc ′ + D × Qsun + E is calculated. Thereafter, the opening X of the air mix door is calculated based on the target outlet temperature (S401). That is, X = F × Tof ² + G + Tof + H is calculated.

FIG. 9 is a flowchart showing details of the outlet mode processing. Here, the blowing mode is determined based on the target blowing temperature (S500). That is, if the target outlet temperature is high, the foot (outlet) mode is set, if the target outlet temperature is medium, the bi-level mode is set, and if the target outlet temperature is low, the vent mode is set.

Thermal sensation and wind speed report processing [Thermal sensation and wind velocity report processing 1] FIG. 10 is a flowchart showing details of the thermal sensation and wind velocity report processing. In the thermal sensation / wind sensation reporting processing, if the operation amount by the temperature setting means CL4 is equal to or less than a predetermined amount, the airflow correction control having a temperature dead zone in which the target value of the airflow is not corrected is executed. If the manipulated variable is less than or equal to the predetermined value, temperature correction control is performed with an airflow dead zone that does not correct the target temperature value. Hereinafter, the control related to the dead zone will be described in detail. Here, first, it is determined whether or not the thermal sensation switch has been pressed (S2600). If it is determined that the thermal sensation switch has been pressed, the operation change amount ΔT of the thermal sensation switch is calculated (S260).
1). That is, ΔT = (value after setting) − (value before setting) is calculated. Thereafter, it is determined whether or not the wind speed switch has been pressed (S2602). If it is determined that the switch has not been pressed, the process proceeds to step S2603.

Step S2603 shows a case where only the thermal sensation switch is operated and the wind speed sensation switch is not operated. Here, the operation change amount ΔW of the wind speed switch is calculated with respect to the operation change amount ΔT of the thermal switch calculated in step S2601. Here, ΔT is the difference between the position of the thermal sensation switch before the operation and the position after the operation, and ΔW is the difference between the position of the wind speed sensation switch before the operation and the position after the operation. In the illustrated example, when ΔT is +1 or −1, ΔW is set to zero. That is, when ΔT is the above value, the target value is not corrected by the wind speed switch. That is, in the operation in which ΔT is −1 to +1, the above range is referred to as a dead zone in the sense that no control is performed on the target value by the wind speed switch.

By executing the above-described control, there is provided an association between the temperature setting means CL4 and the airflow setting means CL5 in which the operation of one means is corrected for the operation of the other means. When each operation amount is within a predetermined range, a dead zone is provided so as not to have an association. For this reason, for example, when the occupant wants to change the temperature and operates the thermal sensation switch, and when the operation amount is equal to or less than a predetermined value, the air volume does not change as in the related art.
Since only the temperature changes, the control reaction to the executed operation is less uncomfortable.

Note that ΔT = 0 corresponds to the case where no operation is performed. Next, the case where ΔT is +2 will be described. As shown, ΔW is +1. Accordingly, if the operation change amount of the thermal sensation switch is ΔT = + 2, the wind speed sensation switch increases ΔW by adding ΔW to the current value. The same applies to values other than the above described ΔT. Here, when both the thermal sensation switch and the wind speed sensation switch are operated, the operation set value of each switch is used as it is by going to step S600 or step S1600.

If it is determined in step S2600 that the thermal sensation switch has not been pressed, then
It is determined whether or not the wind speed switch has been pressed (S260).
4). If it is determined that the switch has been pressed, the operation change amount ΔW of the wind speed switch is determined (S2605). That is, ΔW = (value after setting) − (value before setting) is calculated. After that, the processing shifts to Step S2606.

Step S2606 is a case where only the wind speed switch is operated and the thermal switch is not operated. Here, ΔT is obtained for ΔW. That is, in the illustrated example, if ΔW is −1 to 1, ΔT
Is set to zero. That is, for ΔW = −1 to 1, Δ
This is called a dead zone because it does not affect T. If Δ
If W = 2, the sign of ΔT changes according to the sign of the room temperature deviation ΔTic (calculated in step S1602). That is, if ΔTic is positive, it means that the room temperature Tic has not dropped to the target temperature Tptc ′, so that ΔT = −1 and correction is made to the cooling side.

By executing the above-described control, there is provided an association between the temperature setting means CL4 and the airflow setting means CL5 in which the operation of one means is corrected for the operation of the other means. When each operation amount is within a predetermined range, a dead zone is provided so as not to have an association. For this reason, for example, when the occupant wants to change the temperature and operates the thermal sensation switch, and when the operation amount is equal to or less than a predetermined value, the air volume does not change as in the related art.
Since only the temperature changes, the control reaction to the executed operation is less uncomfortable.

If it is determined in step 2604 that the wind speed switch has not been pressed, this means that neither the thermal switch nor the wind speed switch has been operated, and both ΔT and ΔW are set to zero (S2607). . That is, ΔT = ΔW = 0.

Thereafter, the Δ calculated in the above step is calculated.
Using T, the value of the thermal sensation switch is corrected by adding ΔT (S2608). That is, T = V. T + ΔT. Furthermore, using the ΔW calculated in the above step, the value of the wind speed switch is corrected by adding ΔW (S2609). That is, W = V. W + ΔW. Then, after step S600 (FIG. 11,
12) or after step S1600 (FIGS. 13 to 1).
6)).

In FIG. 11 and FIG. 12, first, an external thermal environment index value Tload is calculated based on the external temperature Tamb and the solar radiation Qsun (S600). That is, Tload = R × Tam + S × Qsun is executed.

Thereafter, the external thermal environment index value Tloa
Then, a target room temperature Tptc with respect to d. Corrected target room temperature Tpt according to the value of T
c and cor are obtained (S602). Next, the target room temperature Tptc obtained in step S601 and the corrected target room temperature Tptc, c obtained in step S602 are described.
The target room temperature Tptc 'corrected by combining with or is obtained (S603). That is, Tptc '= Tptc + Tptc, cor is calculated.

Thereafter, the predetermined upper limit Tptc, max of the target room temperature is compared with the above-mentioned Tptc '(S6).
04), that is, it is determined whether or not Tptc ′> Tptc, max is satisfied. If it is determined that Tptc ′ is larger, the upper limit Tpt of the target room temperature is set as Tptc ′.
ptc and max are applied (S606). That is, Tptc '= Tptc, max. Conversely, if it is determined that Tptc 'is smaller, the lower limit Tptc, m of the predetermined target room temperature is determined.
In and Tptc 'are compared (S605). That is, it is determined whether or not Tptc '<Tptc, min is satisfied, and if Tptc' is determined to be smaller, the lower limit Tpt of the target room temperature is set as Tptc '.
ptc, min is applied (S607). That is, Tptc '= Tptc, min. On the other hand, if it is determined that Tptc 'is larger, the room temperature deviation, that is, the room temperature Tic and the target room temperature T
The blower fan application voltage setting value Vfan is set according to the difference from ptc '(S608).

Thereafter, the value V.sub. In accordance with W, a corrected blower fan voltage Vfan, cor is calculated (S609), and the blower fan applied voltage set value Vfan obtained in step S608 is calculated in step S6.
The correction is performed by the correction amount obtained in step 09, and the corrected value is set as Vfan again (S610). That is, Vfan ← Vfan × (1 + Vfan, cor).

Thereafter, Vfan obtained in step S610 is compared with a predetermined upper limit value Vfan, max of the blower fan voltage (S611). That is, it is determined whether or not Vfan> Vfan, max is satisfied. As a result, if it is determined that Vfan is larger, Vfan is set to Vfan.
n and max are applied (S613). That is, Vfan = Vfan, max. Conversely, if it is determined that Vfan is smaller, then Vfan is compared with a predetermined lower limit value Vfan, min of the blower fan voltage (S61).
2). That is, it is determined that Vfan <Vfan, min. As a result, if it is determined that Vfan is smaller, Vfan, min is applied as Vfan (S614). That is, Vfan = Vfan, min. On the other hand, when it is determined that Vfan is larger, a series of thermal sensation and wind speed sensation reporting processing ends.

In place of FIGS. 11 and 12, FIG.
As shown in 3 to 16, a series of processes described below may be executed. First, the external thermal environment index value Tload is calculated based on the external temperature Tamb and the solar radiation Qsun (S160).
0). That is, Tload = R × Tam + S × Qsun is calculated, and then the target room temperature Tptc for the external thermal environment index value Tload is obtained (S1601). Further, a deviation ΔTptc between the current room temperature Tic and the corrected target room temperature Tptc ′ is calculated (S1602). That is, ΔTptc = Tic−Tptc ′ is calculated. Thereafter, it is determined whether or not the thermal sensation switch has been pressed (S1603). The correction target room temperature Tptc, cor is obtained according to the value of T (S160).
4), thermal sensation switch Learning of T is performed (S160)
8). Conversely, if it is determined that the thermal sensation switch has not been pressed, it is next determined whether or not the area is a learned area (S1605).

That is, the thermal environment is divided into predetermined regions.
For example, an area to be stored is divided into a plurality according to the outside air temperature. Next, when the air conditioning operation by the occupant reaches a predetermined number of times in each area, it is determined that learning has been performed in that area,
Let's call it a learning area. Conversely, a region that has not yet reached the predetermined number is referred to as an unlearned region. In this step, it is determined whether or not it is in the learning area.

If it is determined that the area is the learning area, it is determined whether the absolute value of the room temperature deviation ΔTic is within 2 ° C. (S1606). That is, it is determined whether or not | ΔTic | ≦ 2 ° C. is established. If it is determined that | ΔTic | ≦ 2 ° C., the stored thermal cooling / cooling is performed with respect to the external thermal environment index value Tload. Feeling switch V. The value of T is reproduced for use in control (S1609). Conversely, | ΔTi
If it is determined that c | ≦ 2 ° C., the room temperature deviation ΔT
ptc, the stored thermal sensation switch V.P. The value of T is reproduced for use in control (S1610).

In step S1605,
If it is determined that the area is not the learning area, the thermal sensation switch is not pressed and the room temperature is not corrected because it is an unlearned area (S1607), that is, Tptc '= Tptc.

In step S1608, the thermal sensation switch V.V. Learn T. That is, the illustrated step S
As shown in step S1609 or step S1610, the thermal sensation switch V.V.
The set value of T is learned. Although the value of the thermal sensation switch is an integer value in step S1609 or step S1610, it is calculated and stored by a real value at the time of learning, and the value is stored in step S1609 or step S1.
At the time of reproduction at 610, it is used after being rounded to an integer value.

Next, the target room temperature Tptc and the corrected target room temperature T
target room temperature Tpt corrected by combining ptc and cor
c ′ is obtained (S1611). That is, Tptc '= Tptc + Tptc, cor is calculated. Thereafter, the predetermined upper limit Tptc, max of the target room temperature is compared with the above Tptc '(S1).
612). That is, it is determined whether or not Tptc '> Tptc, max holds. If it is determined that Tptc' is larger, the upper limit Tptc of the target room temperature is set as Tptc '.
ptc and max are applied (S1614). That is, Tptc '= Tptc, max.

On the other hand, if it is determined that Tptc 'is smaller, then the predetermined lower limit T of the target room temperature is determined.
ptc, min is compared with the above Tptc ′ (S16)
13). That is, it is determined whether or not Tptc '<Tptc, min is satisfied, and if Tptc' is determined to be smaller, the lower limit Tpt of the target room temperature is set as Tptc '.
ptc, min is applied (S1615). That is, Tptc ′ = Tptc, min. On the other hand, if it is determined that Tptc 'is larger, the room temperature deviation, that is, the room temperature Tic and the target room temperature T
The blower fan application voltage setting value Vfan is set according to the difference from ptc '(S1616).

Thereafter, it is determined whether or not the wind speed switch has been pressed (S1617). If it is determined that the switch has been pressed, learning of the wind speed switch is performed (S1620). Conversely, when it is determined that the wind speed switch has not been pressed, it is next determined whether or not the current position is in the learning area (S161).
8). Here, when it is determined that it is the learning area, it is further determined whether or not the room temperature deviation is within 2 ° C. (S
1619). That is, it is determined whether or not | ΔTic | ≦ 2 ° C. holds. As a result, | ΔTic |
If it is determined that ≦ 2 ° C., the value V.V. of the wind speed switch with respect to the external thermal environment index value Tload. W is reproduced for use in control (S1621). Conversely, | ΔT
If it is determined that ic | ≦ 2 ° C., the room temperature deviation Δ
The value of the wind speed switch with respect to Tptc. W is reproduced for use in control (S1622).

As described above, in step S1620, learning of the wind speed switch is performed. Illustrated step S162
1 or the wind speed sensation switch V.1 against the external thermal environment index value or the room temperature deviation as in step S1622. The set value of W is learned. Although the value of the thermal sensation switch in step S1621 or step S1622 is an integer value, it is calculated and stored as a real value during learning, and the value is stored in step S1621 or step S1622.
When reproducing with, it is used by rounding it to an integer value.

Next, the value V. The correction blower fan voltage Vfan, cor is calculated according to W (S
1623), Vfan is corrected by the correction amount obtained in step S1623, and the corrected value is set as Vfan again (S1624). That is, Vfan ← Vfan × (1 + Vfan, cor). Thereafter, Vfan obtained in step S1624 is compared with a predetermined upper limit value Vfan, max of the blower fan voltage (S1625). That is, it is determined whether or not Vfan> Vfan, max is satisfied. As a result, if it is determined that Vfan is larger, Vfan is set to Vfan.
n and max are applied (S1627). That is, Vfan = Vfan, max.

On the other hand, if it is determined that Vfan is smaller, then Vfan is compared with a predetermined lower limit value Vfan, min of the blower fan voltage (S16).
26). That is, it is determined whether or not Vfan <Vfan, min holds. As a result, if it is determined that Vfan is smaller, Vfan is set as Vfan.
Apply n and min. That is, Vfan = Vfan, min. On the other hand, when it is determined that Vfan is larger, the processing for reporting the thermal sensation and the wind velocity is terminated.

Manual Switch Processing and Output Processing FIGS. 17 and 18 are flowcharts showing details of the manual switch processing and output processing. Here, first, it is determined whether or not the outlet mode (selection) switch is pressed (S700), and if it is determined that the switch is pressed, the vent outlet mode (S701) is selected according to the position. Level blowing mode (S702), foot blowing mode (S7)
03). Conversely, if it is determined that the outlet mode (selection) switch has not been pressed, and if the switch has not been pressed, the above selected mode is selected and the determined blow mode is set. Thus, the command is output to the outlet setting actuators 22, 23, 24 (S704).

Thereafter, it is determined whether or not the front defroster switch has been pressed (S705). If it is determined that the switch has been pressed, the front defroster is operated (ON) (S706). In this case, the air conditioner compressor (not shown) is operated, the refrigeration cycle is operated, and the evaporator 11 performs dehumidification. Further, the actuators 22, 23, and 24 are operated as the outlet mode to set a defroster outlet mode in which conditioned air is blown to the front window. Specifically, the actuators 22, 23, and 24 are controlled so as to allow only the introduction of the conditioned air to the defroster duct 16 and prevent the introduction of the conditioned air to the vent duct 17 and the foot duct 18. Further, if the air volume is stopped, the air volume is set to a predetermined value. When the temperature of the air-conditioned air blows down due to the dehumidifying action, the opening degree of the air mix door 13 is controlled by the actuator 14 so as to be adjusted to a predetermined blow-out temperature. This makes it possible to remove fogging of the front window.

If it is determined in step S705 that the front defroster switch has not been pressed, the front defroster is stopped (OFF) (S70).
7). That is, if the front defroster is operating, it is stopped and set to a normal air conditioning state.

Thereafter, it is determined whether or not the rear defroster switch has been pressed (S708). If it is determined that the switch has been pressed, the rear defroster is operated (ON) (S708).
709). That is, a current is applied to a heat wire (not shown) embedded in the rear window to heat the rear window and evaporate water droplets adhering to the surface. Also,
If the vehicle has a rear window equipped with a wiper, the wiper is activated. This removes fogging of the rear window.

If it is determined in step S708 that the rear defroster switch has not been pressed,
If the rear defroster is operating, it is stopped (OFF) (S710). Thereafter, it is determined whether or not the target blowing temperature Tof calculated in the above step S400 is equal to or higher than 60 ° C. (S711). That is, it is determined whether or not Tof ≧ 60 ° C. is satisfied. If it is determined that Tof ≧ 60 ° C. is not satisfied, then the target outlet temperature Tof is set to −
It is determined whether the temperature is 20 ° C. or less (S712). That is, it is determined whether or not Tof ≦ −20 ° C. is satisfied. If it is determined that Tof ≦ −20 ° C. is not satisfied, outside air is introduced using the air-conditioning air inlet as outside air (S713). Conversely, Tof ≦ −
If it is determined that 20 ° C. is satisfied, or if it is determined in step S711 that Tof ≧ 60 ° C. is satisfied, the internal air is circulated using the air-conditioning air suction port as the room (S714).

The above steps S711 to S71
In each step of 4, when the target outlet temperature is largely out of the comfortable room temperature range, the room is quickly circulated to the set room temperature by circulating the inside air. However, if the inside air circulation is left, the possibility of causing window fogging due to the humidity contained in the occupant's exhalation increases, so the outside air is usually set to be introduced.

Next, it is determined whether or not the suction port (selection) switch has been pressed (S715). If it is determined that the button has been pressed, external air is introduced (S716) or internal air circulation (S717) depending on the position. After that, the outlet
A command is output to the suction port and the actuator of the air mix door (S718), and further a command is output to the blower fan motor (S719).

[Temporary sensation and wind speed reporting process 2] Next, another thermal sensation and wind speed reporting process according to the present invention will be described. 19 and 20 are flowcharts showing the details of the thermal sensation and wind sensation reporting processing 2 of the air conditioner having the configuration shown in FIG. First, the operating frequency detecting means CL7 uses the thermal sensation switch independently for frequency F. T is detected (S3
600). Next, the frequency of independent use of the wind speed switch F.I. W
(S3601), and the frequency F. of operating both the thermal sensation switch and the wind sensation switch. 2 is detected (S3602). Here, in order to detect whether or not both operations have been performed, a predetermined time from when one operation is performed to when the other operation is performed is set, and during the time, the other operation is performed. Detect whether or not. Here, for example, about 30 seconds is appropriate as the monitoring time. It should be noted that the monitoring time may be appropriately adjusted according to the vehicle running state or the operation of the occupant vehicle. For example, the monitoring time is set longer while the vehicle is running, and shorter when the vehicle is stopped. In this way, when the occupant easily performs the air conditioning operation when the vehicle is stopped, the monitoring time can be shortened to determine whether the operation is the “simultaneous operation”.

Next, the frequency difference ΔF between single use and both operations is calculated (S3603). Here, a value obtained by subtracting the single use frequency from both use frequencies is defined as a frequency difference. That is, ΔF = F. 2- (FT + FW) is calculated. Thereafter, the frequency difference ΔF is compared with a predetermined value (S3604). That is, ΔF> F. It is determined whether or not set is satisfied. If it is determined that the value is larger than the predetermined value, the flag FLAG is set to 1 (FLAG = 1) (S3605). Conversely, if it is determined that the value is smaller than the predetermined value, the flag FLAG is set to 0.
Is set (FLAG = 0) (S3606).

Thereafter, it is determined whether or not the thermal sensation switch has been pressed (S3607). If it is determined that the thermal sensation switch has been pressed, the operation change amount of the thermal sensation switch is calculated (S36).
08). That is, ΔT = (value after setting) − (value of setting value) is calculated. Next, it is determined whether or not the wind speed switch has been pressed (S3609). If it is determined that the wind speed switch has been pressed, the process proceeds to step S600 or S1600. Conversely, when it is determined that the wind speed switch has not been pressed, it is further determined whether or not the flag FLAG is zero (S361).
0). That is, it is determined whether or not FLAG = 0. If it is determined that it is zero, the flow shifts to step S3611. Conversely, if it is determined that it is not zero, the flow shifts to step S3612.

Here, if both the thermal sensation switch and the wind velocity sensation switch are operated, the process proceeds to step S600 or step S1600. If both operations are performed, the respective set values are used for control as they are. No correction is made from one switch to the other.

Step S3611 is the same as step S2 described above.
603. Step S3612 differs from step S3611 in the width of the dead zone.
That is, in step S3611, the dead zone is ΔT = −1 to 1, but in step S3612, the dead zone is as narrow as ΔT = 0. Step S361 above
If the frequency of both operations is higher than the frequency of single operation from 0 to S3612, step S3612 is selected instead of step S3611, and the dead zone width is narrowed. That is, since there are many opportunities to operate both switches, the dead zone is narrowed, and the same effect as operating both switches can be obtained by operating only one of the switches.

Next, it is determined whether or not the wind speed switch has been pressed (S3613). If it is determined that the switch has been pressed, the operation change amount of the wind speed switch is determined (S361).
4). That is, ΔW = (value after setting) − (value before setting) is calculated. On the other hand, when it is determined that the wind speed switch is not pressed, it means that neither the thermal switch nor the wind switch is pressed, and both ΔT and ΔW are set to zero (S3616). That is, ΔT = ΔW = 0. Thereafter, it is determined whether or not the flag FLAG is zero (S3615). If it is determined that the flag FLAG is zero, the process proceeds to step S3617. Conversely, if it is determined that the flag FLAG is not zero, the process proceeds to step S3618. Transition.

Step S3617 is the same as step S2 described above.
606 is the same as the content. In step S3618, the dead zone is narrower than in step S3617.
If the frequency of both operations is high in steps S3615, S3617, and S3618, the dead zone width is narrowed by selecting step S3618, and the effect of correcting one by operating one switch can be more exerted. .

Thereafter, the Δ calculated in the above step is calculated.
Using T, the value of the thermal sensation switch is corrected by adding ΔT (S3619). That is, T = V. T + ΔT. Thereafter, the value of the wind speed switch is corrected by adding ΔW using the ΔW calculated in the above step (S3620). That is, W = V. W + ΔW. Then, after step S600 (FIG. 11,
12) or after step S1600 (FIGS.
16)).

In the above embodiment, the width of the dead zone in which no operational linkage is performed is automatically controlled to an appropriate range. That is, the operation of the temperature setting means CL4 and the airflow setting means CL5 is almost complete. Depending on whether the operation has been performed simultaneously or only one of them, if the operation of both means is performed, the width of the dead zone is gradually narrowed, and the operation of one of the means alone will cause the other to operate. The means can be automatically corrected. As a result, if the occupant operates only one of the means, the other means can also be corrected, so that the number of occupant operations can be reduced, and if only one operation is performed, the width of the dead zone is reduced. By gradually increasing the area where the operation of one means alone does not correct the other means, the correction of the other means is not performed even if the operation amount to one means is relatively large. The control reaction to the operation performed by the occupant can be made more comfortable.

[Declaration Process 3 for Thermal Sense and Wind Speed] Next, another process for reporting a thermal sensation and wind speed according to the present invention will be described. FIGS. 21 and 22 are flowcharts showing details of the thermal sensation and wind speed sensation reporting processing 3 of the air conditioner having the configuration shown in FIG. First, the non-operation time detecting means CL8 operates the thermal sensation switch and the wind speed switch, and then detects the non-operation time of each switch until the next operation is performed (S4600), and operates both switches. From the case, the time until the next single operation is used is the both non-operation time t. 2 and calculate the sum (S460).
1). Thereafter, the time from when the switch is used alone to when both switches are operated next is referred to as a single use non-operation time, which is defined as t. It is calculated as 1 and integrated (S4602). In addition,
The time from both uses to the next use is t. 2 and the time from single use to the next single use is t. It shall be added to 1 respectively.

After that, the integration time t. 2 and t. A ratio of 1 is calculated (S4603). That is, ratio = t. 2 / t. Calculate 1. Next, the ratio ratio is compared with a predetermined value (S4604). That is, ratio> ratio. It is determined whether or not set is satisfied. As a result, when it is determined that the ratio is large, the flag FLAG is set to 1 (FLAG = 1) (S4605). Conversely, ra
If it is determined that tio is small, the flag FLAG is set to 0 (FLAG = 0) (S4606).

Thereafter, it is determined whether or not the thermal sensation switch has been pressed (S4607). If it is determined that the thermal sensation switch has been pressed, the operation change amount of the thermal sensation switch is calculated (S46).
08). That is, ΔT = (value after setting) − (value of setting value) is calculated. Next, it is determined whether or not the wind speed switch has been pressed (S4609). If it is determined that the wind speed switch has been pressed, the process proceeds to step S600 or step S1600. Conversely, when it is determined that the wind speed switch has not been pressed, it is further determined whether or not the flag FLAG is zero (S461).
0). That is, it is determined whether or not FLAG = 0. If it is determined that it is zero, the flow shifts to step S4611. On the other hand, if it is determined that it is not zero, the flow shifts to step S4612.

Here, if both the thermal sensation switch and the wind sensation switch are operated, the process proceeds to step S600 or step S1600, and if both operations are performed, the respective set values are used for control as they are. , No correction is made from one switch to the other.

Step S4611 is the same as step S2 described above.
603. Step S4612 is different from step S4611 in the width of the dead zone.
That is, in step S4611, the dead zone is ΔT = −1 to 1, but in step S4612, the dead zone is as narrow as ΔT = 0. Step S461 above
If the frequency of both operations is higher than the frequency of single operation from 0 to S4612, step S4612 is selected instead of step S4611, and the dead zone width is narrowed. That is, since there are many opportunities to operate both switches, the dead zone is narrowed, and the same effect as operating both switches can be obtained by operating only one of the switches.

Next, it is determined whether or not the wind speed switch has been pressed (S4613). If it is determined that the switch has been pressed, the operation change amount of the wind speed switch is determined (S461).
4). That is, ΔW = (value after setting) − (value before setting) is calculated. Conversely, if it is determined that the wind speed switch is not pressed, it means that neither the thermal switch nor the wind speed switch is pressed, and both ΔT and ΔW are set to zero (S4616). That is, ΔT = ΔW = 0. Thereafter, it is determined whether or not the flag FLAG is zero (S4615). If it is determined that the flag FLAG is zero, the process proceeds to step S4617. Conversely, if it is determined that it is not zero, the process proceeds to step S4618. Transition.

Step S4617 is the same as step S2 described above.
606 is the same as the content. In step S4618, the dead zone is narrower than in step S4617.
If the frequency of both operations is high in steps S4615, S4617, and S4618, the dead zone width is narrowed by selecting step S4618, and the effect of correcting one by operating one switch can be more exerted. .

Thereafter, the Δ calculated in the above step is calculated.
Using T, the value of the thermal sensation switch is corrected by adding ΔT (S4619). That is, T = V. T + ΔT. Thereafter, the value of the wind speed switch is corrected by adding ΔW using the ΔW calculated in the above step (S4620). That is, W = V. W + ΔW. Then, after step S600 (FIG. 11,
12) or after step S1600 (FIGS.
16)).

Note that this control calculates the respective continuous use time ratios of both the operation and the single operation. This continuous use time can be regarded as satisfaction with the operation, and the longer the continuous use time, the higher the satisfaction. Therefore, the higher the time ratio of the use of both, the narrower the dead zone width, so that the same effect can be obtained even in the single operation, and conversely, the lower the time ratio, the larger the dead zone width. The reaction on the control side as a single operation can be clarified, and the setting can be easily performed by the occupant.

[Declaration Processing 4 of Thermal sensation and Wind Speed] Next, another processing of reporting the thermal sensation and wind velocity according to the present invention will be described. 23 and 24 show other thermal sensations of the air conditioner,
It is a flowchart which shows the detail of the wind speed report processing 4.
First, the upper limit ΔTic, high of the room temperature deviation ΔTic is set (S5600), and the lower limit ΔTi of the room temperature deviation ΔTic is set.
c and low are set (S5601), and then the room temperature deviation ΔTic is calculated (S5602). That is, ΔTic = Tic−Tptc ′ is calculated.

Thereafter, the room temperature deviation is compared with the upper limit (S5603). That is, it is determined whether ΔTic> ΔTic, high is satisfied. As a result, when it is determined that ΔTic is small, the room temperature deviation is compared with its lower limit (S5604). That is, it is determined whether ΔTic <ΔTic, low is satisfied. As a result, if it is determined that ΔTic is small, the flag FLAG is set to 1 (FLAG = 1) (S5605). Conversely, ΔTi
If it is determined that c is large, the flag FLAG is set to 0 (FLAG = 0) (S5606).

Thereafter, it is determined whether or not the thermal sensation switch has been pressed (S5607). If it is determined that the thermal sensation switch has been pressed, the operation change amount of the thermal sensation switch is calculated (S56).
08). That is, ΔT = (value after setting) − (value before setting) is calculated. Next, it is determined whether or not the wind speed switch has been pressed (S5609). If it is determined that the wind speed switch has been pressed, the process proceeds to step S600 or S1600. Conversely, if it is determined that the wind speed switch has not been pressed, it is further determined whether or not the flag FLAG is zero. That is, it is determined whether or not FLAG = 0. If it is determined that it is zero, the flow shifts to step S5611. On the other hand, if it is determined that it is not zero, the flow shifts to step S5612.

Here, if both the thermal sensation switch and the wind speed sensation switch are operated, the process proceeds to step S600 or step S1600, and if both operations are performed, the respective set values are used for control as they are. , No correction is made from one switch to the other.

Step S5611 is the same as step S2 described above.
603. Step S5612 is different from step S5611 in the width of the dead zone.
That is, in step S5611, the dead zone is ΔT = −1 to 1, but in step S5612, the dead zone is as narrow as ΔT = 0. Step S561 above
If the frequency of both operations is higher than the frequency of single operation from 0 to S5612, step S5612 is selected instead of step S5611, and the dead zone width is narrowed. That is, since there are many opportunities to operate both switches, the dead zone is narrowed, and the same effect as operating both switches can be obtained by operating only one of the switches.

Next, it is determined whether or not the wind speed switch has been pressed (S5613). If it is determined that the switch has been pressed, the operation change amount of the wind speed switch is determined (S561).
4). That is, ΔW = (value after setting) − (value before setting) is calculated. Conversely, if it is determined that the wind speed switch is not pressed, it means that neither the thermal switch nor the wind speed switch is pressed, and both ΔT and ΔW are set to zero (S5616). That is, ΔT = ΔW = 0. Thereafter, it is determined whether or not the flag FLAG is zero (S5615). That is, it is determined whether or not FLAG = 0. As a result, if it is determined that it is zero, the flow shifts to step S5617, and if it is determined that it is not zero, the flow shifts to step S5618.

Step S5617 is the same as step S2 described above.
606 is the same as the content. In step S5618, the dead zone is narrower than in step S5617.
If the frequency of both operations is high in steps S5615, S5617, and S5618, the dead zone width can be narrowed by selecting step S5618, and the effect of correcting the other can be more exerted by operating one switch. .

Thereafter, the Δ calculated in the above step is calculated.
Using T, the value of the thermal sensation switch is corrected by adding ΔT (S5619). That is, T = V. T + ΔT. Thereafter, the value of the wind speed switch is corrected by adding ΔW using the ΔW calculated in the above step (S5620). That is, W = V. W + ΔW. Then, after step S600 (FIG. 11,
12) or after step S1600 (FIGS.
16)).

By controlling these steps, if the thermal environment is within the predetermined range, the flag FLAG is set to zero in step S5606, whereby steps S5612 and S5618 are selected to reduce the dead zone width. it can. Here, only two divisions within the predetermined range and outside the range are performed for the thermal environment, but it goes without saying that it is possible to select a more appropriate dead zone width by increasing the number of divisions.

[Declaration Processing 5 of Thermal Sense and Wind Speed] Next, another report processing of thermal sensation and wind speed according to the present invention will be described. FIG. 25 is a flowchart illustrating details of another thermal / wind sense reporting process 5 of the air conditioner. First,
It is determined whether both the thermal sensation switch and the wind sensation switch have been operated (S6600). As a result, when it is determined that both are operated, it is determined whether or not the set value of the thermal sensation switch is outside the temperature dead zone (S660).
1). If it is determined that the value is out of the range, the amount of the air volume correction is changed to the value set by the wind speed switch (S660).
2). Thus, the amount of air volume correction can be set to a value set by the occupant.

Next, it is determined whether or not the set value of the wind speed switch is outside the range of the air volume dead zone (S6603). As a result, when it is determined that the temperature is out of the range, the amount of the temperature correction is changed to the value set by the thermal sensation switch (S660).
4). Thus, the temperature correction amount can be set to a value set by the occupant. If it is determined in step S6601 that the set value of the thermal sensation switch is not out of the range of the temperature dead zone, the process jumps to step S6603. If it is determined that both of the switches have not been operated, in step S6603,
When it is determined that the set value of the wind speed switch is not out of the range of the airflow dead zone, as a step subsequent to step S6604, the above-mentioned steps S600 and thereafter (FIG. 11, 1)
2) or after step S1600 (FIGS. 13 to 1).
6)).

In this case, in step S6602 and step S6604, the occupant set value is directly changed to the correction amount, but the past operation set value is stored and processed by a statistical method such as averaging. The latter value may be used as the correction amount. By doing so, the control can be stabilized.

[Thermal / Wind Feeling Reporting Process 6] Next, another thermal / wind feeling reporting process according to the present invention will be described. FIG. 26 is a flowchart showing details of another heat / cool sense / wind speed report processing 6 of the air conditioner.
The processing is inserted between step S3620 and step S600 or S1600 in the flowchart shown in FIG. When the processing in step S3620 ends,
Next, the final set value V.V. T is the upper limit of the thermal switch. T. It is determined whether it is larger than max (S7600). That is, T> V. T. It is determined whether or not max is satisfied. As a result, V.I. When it is determined that T is large, V.T. V. T. max is applied (S7601). That is, T = V. T. max.

On the other hand, V. If it is determined that T is small, the final set value V.V. T is the lower limit of the thermal sensation switch. It is determined whether it is smaller than Tmin (S7602). That is, T <V. T. It is determined whether or not min is satisfied. As a result, V.I. When it is determined that T is small, V.T. V. T. min is applied (S7603). That is, T = V. T. min. Conversely, V. If it is determined that T is large,
The process shifts to the steps after step S600 (see FIGS. 11 and 12) or steps after step S1600 (see FIGS. 13 to 16).

Thereafter, the final setting value V.V. W is the upper limit of the wind speed switch. W. It is determined whether it is larger than max (S7604). That is, W. > V. W. It is determined whether or not max is satisfied. As a result, V.I. If it is determined that W is large, V.W. W as V. W. max is applied (S7605). That is, W. = V. W. max. Conversely, V. If it is determined that W is small,
Next, the final setting value V.V. W is the lower limit of the wind speed switch. W. It is determined whether it is smaller than min (S7606). That is, W. <V. W. It is determined whether or not min is satisfied.

As a result, V.V. If it is determined that W is small, V.W. W as V. W. min (S76)
07). That is, W = V. W. min. Conversely, V. If it is determined that W is large, as the next step of steps S7605 and S7607,
The process shifts to the steps after step S600 (see FIGS. 11 and 12) or steps after step S1600 (see FIGS. 13 to 16).

[0106]

As described above, in the air conditioner according to the first aspect, between the temperature setting means and the air flow setting means, the operation of one means is corrected for the operation of the other means. In addition to the above-mentioned relationship, the respective operation amounts are not linked in a predetermined range, so that the control reaction to the executed operation is less uncomfortable.

According to the second aspect of the present invention, since the width of the dead zone in which no operational linkage is performed is automatically controlled to an appropriate range, the control reaction to the operation performed by the occupant is less uncomfortable. .

In the invention according to claim 3, the non-operating time for both use and the non-operating time for single use are calculated and integrated, and the width of the dead zone becomes smaller as the both non-operating time becomes longer. The time from to the next operation is regarded as the time satisfied by the operation, and the control response to the executed operation is adjusted to adjust the width of the dead zone according to the time of satisfaction when both are used and when the device is used alone. The discomfort is further reduced.

In the invention according to claim 4, the correction direction of the temperature setting means when the airflow setting means is operated is hot or cold with respect to a target thermal environment such as a room temperature deviation. Since the correction direction is changed according to the criterion described above, it is possible to accurately match the occupant's sense of warm / cool and wind speed.

According to the fifth aspect of the present invention, when both the temperature setting means and the air flow setting means are performed almost simultaneously, the correction of the other means by one operation is not performed and the respective means are not corrected. In order to utilize the setting by the operation as it is, if the above-mentioned association by automatic control does not match the occupant's warm / cool, wind speed sensation, the occupant can freely set the temperature and wind speed, so that the above association is provided. Also, it is possible to provide a degree of freedom in setting when the feeling does not match the occupant's feeling.

Further, in the invention according to claim 6, the frequency or the number of times that only one of the temperature setting means and the airflow setting means is operated, and the frequency or number of times that both are operated within a predetermined time. Since the width of the dead zone was reduced as the frequency or number of times both operations were increased,
The dead zone can be adjusted to a more optimal width.

Further, in the invention according to claim 7, since the width of the dead zone is changed according to the thermal environment, the correspondence between the operation and the reaction by the operation becomes clear, and the control which is easy for the occupant to realize is realized. Can be.

In the invention according to claim 8, the width of the temperature dead zone or the airflow dead zone is individually stored for each thermal environment. For example, when the temperature is close to a comfortable thermal environment, the dead zone is stored. An optimum dead zone width can be set according to each thermal environment, such as narrowing the width and widening the dead zone when far from a comfortable thermal environment.

According to the ninth aspect of the present invention, the corrected air volume obtained by adding the air volume adjustment amount to the current air volume is compared with the set air volume set amount, and if the air volume set amount is larger than the corrected air volume. For example, the occupant determines that he or she wants a larger airflow adjustment amount, and makes the width of the temperature dead zone smaller so that the airflow adjustment amount becomes larger than the current width. Similarly,
If the direction of heating the vehicle interior thermal environment is higher, the width of the airflow dead zone is smaller if the set temperature is higher than the corrected temperature, and conversely, if the direction of cooling the vehicle interior thermal environment is lower than the corrected temperature. If the set temperature is low, the width of the airflow dead zone is made smaller, so that the width of each dead zone can be set appropriately.

In the invention according to claim 10,
The minimum and maximum widths are set in each dead zone.
If it is within the maximum range, the width of the dead zone is adjusted, but only within the minimum and maximum ranges, for example, by adjusting the ratio of air volume correction to the temperature adjustment amount, the width of the dead zone is reduced to zero or zero. Since there is no proximity, it is possible to avoid the problem that the reaction to the operation becomes unclear, and since the width of the dead zone does not take a value larger than an appropriate range, for example, for a large amount of temperature control amount, The air volume correction is so small that the air volume correction does not substantially work.

In the invention according to claim 11,
Instead of setting the target temperature in the cabin specifically, it is a case where an operation system that increases or decreases the target value with respect to the current target value is adopted. Since sensible input operations can be performed, operability is further improved.
