The above-described face air outlet is installed at the center of the vehicle interior instrument panel in the left-right direction of the vehicle. The face air outlet has a swing grill 10 as wind direction adjusting means capable of adjusting the blowing direction of the conditioned air. Is provided.

The swing grill 10 will be described with reference to FIG. FIG. 2 shows the swing grill 1 shown in FIG.
FIG. 2 is a schematic cross-sectional view of the device viewed from an A direction. The swing grill 10 includes a plurality of vertical louvers 11 for adjusting the blowing direction of the vehicle in the left-right direction among the blowing directions of the conditioned air, and a plurality of horizontal louvers for adjusting the blowing direction of the vehicle in the vertical direction among the blowing directions of the conditioned air. 12 are provided.

Of these louvers 11 and 12, the vertical louver 11 is driven by a step motor 13. Specifically, an arm 14 is attached to the rotation shaft of the step motor 13, and the arm 14 and the vertical louver 11 are connected by a link lever 15. When the step motor 13 is driven based on the output signal of the microcomputer 31, the arm 14 swings and the arm 14
As a result, the link lever 15 is displaced in the vehicle left-right direction, and the direction of the vertical louver 11 in the vehicle left-right direction is adjusted.

The swing grill 10 is provided with a potentiometer 16 as a blow-out direction detecting means for detecting a blow-out direction of the conditioned air in the vehicle left-right direction. The potentiometer 16 detects the rotation position (rotation angle) of the rotation shaft of the step motor 13, and the signal is input to the microcomputer 31. The microcomputer 31 calculates the direction of the vertical louver 11 in the left-right direction of the vehicle based on the signal of the potentiometer 16.

FIG. 3 is a flowchart showing the entire control executed by the microcomputer 31 when the automatic control state of the air conditioner is set by an AUTO switch (not shown) provided on the operation unit 37. Will be described with reference to FIG.

The microcomputer 31 starts the control at step 100 when the IG is turned on, and at step 110
To set initial values such as various conversions and flags. In the next step 150, while inputting the environmental condition signals from the inside temperature sensor 33, the outside temperature sensor 34, and the solar radiation sensor 35, the signal from the potentiometer 16 is input, and further operated by the temperature setting switch 36 and the operation unit 37. Enter the switch status.

In the next step 200, step 150
The target blowing temperature (TAO) of the conditioned air blown into the vehicle interior is calculated according to the following equation 1 based on the environmental condition signal and the like input in step (1).

[0032]

## EQU1 ## TAO = KSET × TSET-KR × TR-K
AM × TAM−KS × TS + C, where KSET, KR, KAM, and KS are coefficients, C is a constant, TSET is the set temperature, TR is the inside air temperature, TAM is the outside air temperature, and TS is the amount of solar radiation.

Next, the routine proceeds to step 300, where the opening of the air mix damper 22b is calculated with respect to TAO, and the actuator for driving the air mix damper (not shown) is controlled via the drive circuit 30 so that the opening is obtained. This controls the temperature of the conditioned air blown out from the outlet into the vehicle interior.

Next, the routine proceeds to step 400, where the amount of air blown is calculated, and the voltage (blower voltage) applied to the blower motor 24 via the drive circuit 30 is controlled. This allows the fan 23
By controlling the number of rotations, the amount of air blown into the vehicle compartment is controlled. Next, the process proceeds to step 500, where the inside / outside air introduction ratio by the inside / outside air switching damper 22a is calculated, and an inside / outside air switching damper driving actuator (not shown) is controlled via the drive circuit 30.

Next, the routine proceeds to step 600, where the blow-out mode is calculated, and the defroster damper 22c and the face damper 22 are calculated.
d and an actuator (not shown) for driving the foot damper 22 e are controlled via the drive circuit 30. In addition,
When the blowout mode is manually selected, each of the dampers 22c, 22d and 22e is controlled so as to be in the selected mode.

Next, the routine proceeds to step 700, where a compressor (not shown) is controlled. Next, the routine proceeds to step 800, where the wind direction is controlled. This wind direction control will be described later.
After the process in step 800, the process returns to step 150 to read various signals again, and thereby, in step 200, TA
O is calculated according to the TAO and the state of the switch read in step 150.
The control of air conditioning is repeated by 00, 500, 600, 700, and 800.

FIG. 4 is a detailed flowchart of step 800 for controlling the wind direction, which will be described below with reference to FIG.

Here, the microcomputer 31 includes:
A large number of wind direction control characteristics (maps) are stored for each of the conditions of the outside air temperature and the amount of solar radiation for obtaining the direction of the conditioned air from the face outlet based on the environmental conditions related to the air conditioning in the vehicle cabin. Then, one wind direction control characteristic is selected from a number of wind direction control characteristics based on the outside air temperature and the amount of solar radiation, and the blowout direction of the conditioned air is determined based on the inside air temperature from the selected wind direction control characteristics. Has become.

FIG. 5 shows an example of the wind direction control characteristic.
In FIG. 5, the solid line is a predetermined wind direction control characteristic, and the fixed mode or the swing mode is determined based on the inside air temperature. The fixed mode is a control state in which the blowout direction of the conditioned air from the face outlet is fixed in a fixed direction (in the present embodiment, the occupant direction). On the other hand, the swing mode is a control state in which the blowing direction of the conditioned air from the face outlet changes periodically. In the present embodiment, as shown in FIG. 6, the blowing direction of the conditioned air in the swing mode changes between the occupant direction and the direction directly behind the vehicle (that is, the non-occupant direction away from the occupant).

In FIG. 4, in step 810, 1 is set based on the outside air temperature and the amount of solar radiation inputted in step 150.
One of the wind direction control characteristics is selected, and the blowing direction of the conditioned air from the face outlet is determined based on the inside air temperature based on the selected wind direction control characteristics.

In the next step 820, it is determined whether or not the wind direction has been manually operated (changed) as described below. That is, the microcomputer 31 compares the direction of the vertical louver 11 calculated based on the output signal to the step motor 13 with the direction of the vertical louver 11 calculated based on the signal of the potentiometer 16, and when the two match. Determines that there is no manual operation of the wind direction. On the other hand, when the direction of the vertical louver 11 is changed by the occupant, the vertical louver 11 calculated based on the output signal to the step motor 13 is output.
Does not match the direction of the vertical louver 11 calculated based on the signal of the potentiometer 16, and in this case, it is determined that there is a manual operation of the wind direction.

No manual operation of the wind direction (Step 820 is N
In the case of O), the process proceeds to step 830, in which the swing grill 10 is controlled so as to be in the air-conditioning air blowing direction determined in step 810. Specifically, for example, at the beginning of air conditioning at the time of cooling down in summer, the fixed mode is selected because the inside air temperature is high, and the direction of the vertical louver 11 is controlled so that the conditioned air is blown out toward the occupant. Inside air temperature is first
When the temperature drops to the set temperature TR1, the swing mode is selected, and the vertical louver 1 is selected based on the swing characteristics shown in FIG.
The direction of 1 is changed periodically.

On the other hand, there is a manual operation of the wind direction (step 82).
If 0 is YES), the process proceeds to step 840 to change (learn) the wind direction control characteristics. Specifically, for example, at the time of cool-down in summer, the inside air temperature becomes equal to the first set temperature TR.
When the inside air temperature TR2 is higher than 1, that is, when the fixed mode is selected, if the manual operation of the wind direction is performed to reduce the cooling feeling, the manual operation of the wind direction is performed as shown by a broken line in FIG. Then, the wind direction control characteristic is changed so that the mode is switched from the fixed mode to the swing mode at the inside air temperature TR2 at the time when the operation is performed. Then, after changing the wind direction control characteristics in step 840, the process proceeds to step 830,
At 30, the swing mode is immediately executed.

In the next step 810, the direction of the conditioned air from the face air outlet is determined based on the changed air direction control characteristics. Therefore, the taste of the occupant is learned, and the timing of switching from the fixed mode to the swing mode or the timing of switching from the swing mode to the fixed mode can be adjusted to the occupant's preference, so that the user does not need to manually operate the next time. The wind direction control according to the passenger's preference is automatically performed.

(Second Embodiment) As a method of changing the wind direction,
Generally, an operation is performed in which the wind direction is directed toward the occupant at the beginning of air conditioning at the time of cooling down (when the inside air temperature is high), and when a certain sense of warmth is satisfied, the wind direction is removed from the occupant. Therefore, in the second embodiment, the change (learning) of the wind direction control characteristics is performed based on the sensation of the occupant.

In this embodiment, a skin temperature sensor for detecting the occupant's skin temperature is added to the vehicle air conditioner shown in FIG. 1, and the occupant's warmth is estimated from the skin temperature detected by the skin temperature sensor.
As the skin temperature sensor, for example, an infrared sensor capable of detecting the occupant's skin temperature in a non-contact manner is used.

Further, a large number of wind direction control characteristics (maps) are stored for each condition of the outside air temperature and the amount of solar radiation, and one wind direction control characteristic is selected from among a number of wind direction control characteristics based on the outside air temperature and the amount of solar radiation. . FIG. 7 shows an example of the wind direction control characteristic. In FIG. 7, the solid line indicates the predetermined wind direction control characteristic. In the present embodiment, the fixed mode or the swing mode is determined based on the occupant's thermal sensation estimated from the skin temperature. It is supposed to.

For example, at the beginning of air conditioning at the time of cool-down in summer, the occupant's thermal sensation is usually slightly hot or very hot, so the fixed mode is selected and the conditioned air is blown toward the occupant vertically. The direction of the louver 11 is controlled. When the inside air temperature decreases due to the air conditioning and the occupant's warm feeling becomes slightly cooler, the swing mode is selected, and the direction of the vertical louver 11 is periodically changed based on the swing characteristics shown in FIG.

Here, when the occupant is not feeling warm during cool down, for example, if a manual operation of the wind direction is performed to reduce the cooling sensation, as shown by a broken line in FIG.
The wind direction control characteristic is changed so that the mode is switched from the fixed mode to the swing mode when the occupant's thermal sensation becomes insensitive.

According to the present embodiment, when the blowing direction of the conditioned air is changed by the manual operation, the wind direction control characteristic is changed. Therefore, the preference of the occupant is learned, and the manual operation is not required from the next time. Even in this case, it is possible to automatically control the wind direction according to the occupant's preference according to the occupant's warmth. In addition, since the wind direction is controlled according to the occupant's feeling of warmth, the wind direction can be controlled in accordance with the occupant's feeling.

(Other Embodiments) In the first embodiment, when the occupant changes the wind direction by manual operation, the vertical louver 11 is directly operated. However, the fixed mode is changed from the swing mode to the swing mode or from the swing mode to the fixed mode. A wind direction switch for switching to the mode may be provided, and the mode may be switched between the fixed mode and the swing mode by operating the wind direction switch. Then, when the wind direction switch is operated, it is determined in step 820 in FIG. 4 that there is a manual operation of the wind direction.

In the first embodiment, when the direction of the vertical louver 11 is changed by manual operation while the fixed mode is selected, the mode is switched from the fixed mode to the swing mode. If an operation is performed to remove the wind direction facing the occupant from the occupant direction in the selected state, it is considered that the occupant feels that the current airflow is large, so in such a case, It is also possible to change the wind direction and reduce the amount of air blow.

When the fixed mode is selected, the manual air volume changeover switches (air volume setting means) 371 and 372
When the air volume is reduced by operating the button, the air volume may be reduced and the mode may be switched to the swing mode.

In the first embodiment, the wind direction control characteristic is changed so that when the direction of the vertical louver 11 is changed by manual operation while the fixed mode is selected, the mode is switched from the fixed mode to the swing mode. However, if the direction of the vertical louver 11 is changed by manual operation when the fixed mode is selected, the direction of the vertical louver 11 set by the manual operation is learned without switching the mode. You may do it. That is, the wind direction control characteristic is changed at step 840 in FIG. 4 so that the direction of the vertical louver 11 is changed at the inside air temperature when the manual operation is performed.

Further, in the second embodiment, the swing pattern when the swing mode is selected changes the blowing direction of the conditioned air in a constant pattern with respect to time as shown in FIG. Alternatively, the swing pattern when the swing mode is selected may be such that the blowing direction of the conditioned air is changed based on the occupant's thermal sensation so that the occupant's thermal sensation is constant. Specifically, for example, by controlling the wind direction so that the wind direction is directed toward the occupant when the occupant temperature is not sensed and the wind direction is removed from the occupant when the occupant temperature is slightly cool, the occupant's temperature is reduced. It can be in a certain range of insensitive or slightly cool.
