Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle capable of correcting a stop position of a louver fin for changing a blowing direction of conditioned air blown from an air outlet of an air conditioning duct and a center position of a target swing range of the louver fin. The present invention relates to an air conditioner for a vehicle.

[0002]

2. Description of the Related Art Conventionally, air-conditioning air blown from a face air outlet of an air-conditioning unit is changed according to a temperature difference between an inside air temperature detected by an inside air temperature sensor and a set temperature set by a temperature setting device. Vehicular air conditioner in which the blowing direction is changed (first conventional example: for example, Japanese Patent Laid-Open No. 57-10791
No. 2) is known.

[0003] Conventionally, even when the conditioned air blown out from the face air outlet of the air conditioning unit is in a direction avoiding the occupant, the amount of insolation detected by the insolation sensor exceeds the predetermined amount of insolation. In this case, there is also known a vehicle air conditioner (second conventional example: for example, Japanese Patent Application Laid-Open No. 59-160617) in which the blowing direction of the conditioned air is directed to the occupant.

[0004]

However, in recent years, the layout of the passenger compartment has been liberalized (so-called seat arrangement).
Is progressing. For example, there are seat slides for moving a third seat largely in the front-rear direction of the vehicle, for example, a rotating facing seat for rotating a second seat by 180 °, an all-flat seat for fully reclining all seats, and the like.

[0005] In the case of a vehicle (one-box car) equipped with such a seat capable of arranging a plurality of seats, even if the air-conditioning air is blown out so as to have the blowing direction as initially set at the time of sunshine or cool down. Or, even if the position where the occupant is located is set as the target position and the control is performed so that the air-conditioning air blowing direction swings around the target position,
It is conceivable that the position of the occupant is significantly deviated from the initial position. In this case, since the direction of the air-conditioned air blows out of the position where the occupant is located, there is a problem that the occupant's air-conditioning feeling, particularly the cooling feeling, is reduced. Also, the front seats are not as good as the middle and rear seats, but are dissatisfied with the initial settings due to the occupant's physique, posture, seat position, and the like. Here, it is conceivable to install a dedicated sensor for detecting the position where the occupant is located in the vehicle and to blow out the conditioned air toward the position where the occupant is detected by the sensor. The necessity of adding a dedicated sensor causes a problem that the number of parts increases and the price of the whole vehicle becomes expensive.

On the other hand, when the temperature difference between the in-vehicle set temperature and the in-vehicle temperature is equal to or more than a predetermined value, the swing of the wind deflecting blade (louver) is stopped, and the temperature difference between the in-vehicle set temperature and the in-vehicle temperature is less than the predetermined value. In such a case, a vehicle air conditioner (third conventional example: for example, Japanese Patent Publication No.
No. 8621) is known. However, when the occupant feels that the predetermined value is still hot for the occupant, the louver swings in a direction to avoid the occupant's direction again as long as the louver is swinging back to his own direction as long as the louver is less than the predetermined value. Therefore, there is a problem that the occupant cannot reflect the desired air-conditioning state in the control. Conversely, when the occupant feels cold, even if he tries to remove the louver that has swung from the direction of the occupant, the louver will swing again as long as the swing conditions are satisfied. There is a problem that it cannot be reflected in control.

Here, irrespective of the original louver swing control, it is conceivable that the louver swing is stopped for a predetermined time or more to reflect the air conditioning state desired by the occupant in the control. When the temperature of the blown conditioned air is very low, the area where the conditioned air is blown for a long time becomes local cooling, and the occupant feels cold and is uncomfortable. In addition, when the solar radiation hitting the occupant's body is very strong, if the air conditioning wind is not applied for a long time, the passenger feels hot and is uncomfortable.

[0008]

SUMMARY OF THE INVENTION In view of the above problems, the present invention does not require the addition of a dedicated sensor for detecting the position of an occupant. The purpose is to be able to correct the position. In addition, the present invention, in view of the above problems,
It is an object of the present invention to allow a passenger to reflect a desired air-conditioning state in control.

[0009]

According to the first aspect of the present invention, when the stop position command means is instructed to stop the oscillating motion of the blow-off state varying means, the air-conditioning duct blows through the air outlet. If the state of the conditioned air to be blown is shifted from the position where the occupant is, the occupant directly moves the blowing state changing means so that the state of the conditioned air blown from the air outlet is directed to the position of the occupant. . As a result, the current position of the blow state variable means detected by the blow state detecting means differs from the stop position of the blow state variable means instructed by the stop position command means. In such a case, the stop position of the blowing state changing means instructed by the stop position instructing means is output to the stop position instructing means so as to be corrected to the current position changed by the operation of the occupant or in the vicinity thereof.
Therefore, without adding a dedicated sensor for detecting the position where the occupant is, it is possible to correct the target blowing state of the conditioned air according to the position where the occupant is. For this reason, even if the position of the occupant is significantly deviated from the initial position by changing the state of the seat of the vehicle, the conditioned air blown from the air outlet of the air conditioning duct may not remove the occupant. Absent. Thus, the air-conditioning feeling of the occupant can be improved by the air-conditioning air blowing from the air outlet of the air-conditioning duct being directed toward the occupant.

According to the second aspect of the present invention, when a command is issued from the stop position storage means to stop the blow state changing means at the previously set initial position, the blow state changing means is controlled at the initial position. Is controlled such that the actuator stops. When a correction command is input from the stop position correcting means, the stop position storing means rewrites the stop position of the blow state changing means to the current position detected by the blow state detecting means. According to the third aspect of the invention, when the manual setting means instructs the blow state changing means to stop at the manual operation position determined by the manual operation of the occupant, the blow state variable at the manual operation position. The operating state of the actuator is controlled such that the means stops.

According to the fourth aspect of the present invention, when the blowing state changing means is oscillating, the blowing state of the conditioned air blown from the air outlet of the air conditioning duct is shifted from the position where the occupant is. In this case, the occupant directly moves the blowing state changing means so that the conditioned state of the conditioned air blown out from the air outlet is directed to the position where the occupant is. As a result, the current position of the blowing state variable means differs from the target position predicted from the operation speed of the actuator determined by the target position determining means. In such a case, the center position of the target swing range of the blowing state changing means is output to the center position command means so as to be corrected to the current position changed by the operation of the occupant.
As a result, from the next time, the blow state changing means swings in the target swing range around the corrected center position. Therefore, the same effect as that of the first aspect can be achieved.

According to the fifth aspect of the present invention, when a command is issued from the center position storage means to cause the blowout state variable means to oscillate about the previously set initial position, the initial position is set. The operation state of the actuator is controlled such that the blowout state variable means swings in a target swing range centered on. When a correction command is input from the center position correcting means, the center position storing means rewrites the center position of the target swing range of the blowing state changing means to the current position detected by the blowing state detecting means. According to the sixth aspect of the present invention, when the manual setting means instructs the blowing state variable means to swing around the manual operation position determined by the manual operation of the occupant, the manual operation is performed. The operating state of the actuator is controlled such that the blowing state variable means swings in a target swing range centered on the position.

According to the present invention, when the air-conditioning state detected by the air-conditioning state detecting means is largely different from the target air-conditioning state set by the air-conditioning state setting means, the swing of the blowing state changing means is changed. By controlling the operation state of the actuator so that the dynamic movement stops at the center position of the target swing range of the blow state changing means, the conditioned air blown out from the air outlet of the air conditioning duct locally hits the occupant. Thereby, the air conditioning feeling of the occupant can be improved. According to the invention described in claim 8, when the amount of solar radiation detected by the amount of solar radiation detecting means is equal to or greater than a predetermined amount of solar radiation, the swinging motion of the blowing state variable means causes the target swing of the blowing state variable means to change. By controlling the operation state of the actuator so as to stop at the center position of the movement range, the conditioned air blown from the air outlet of the air conditioning duct locally hits the occupant. Thereby, the air conditioning feeling of the occupant can be improved. According to the ninth aspect of the present invention, when the inside air temperature detected by the inside air temperature detecting means is significantly different from the set temperature set by the temperature setting means, the swinging motion of the blowing state variable means is changed. By controlling the operating state of the actuator so as to stop at the center position of the target swing range of the blowing state changing means, the conditioned air blown from the air outlet of the air conditioning duct locally hits the occupant. Thereby, the air conditioning feeling of the occupant can be improved.

According to the tenth aspect of the present invention, the occupant operation determining means determines that the occupant has operated the blowing state variable means when the blowing state variable means is oscillating in a predetermined swing range. In this case, at least one swing end of the swing range of the blow-out state changing means is limited according to the operation amount of the blow-out state change means by the occupant. Thereby, since the direction of the blowing state variable means does not face the adjacent air conditioning zone, the conditioned air does not enter the adjacent air conditioning zone, and the independent control of the adjacent air conditioning zone can be maintained.

According to the eleventh aspect of the present invention, the occupant operation determination means determines that the occupant has operated the blowout state variable means when the blowout state variable means is oscillating in a predetermined swing range. In this case, when the swing range before the operation of the occupant cannot be satisfied in order to restrict the blowing direction of the conditioned air to the adjacent air conditioning zone, the swinging motion of the blowing state changing means is continued until a predetermined time elapses. By stopping or decelerating, the influence on the adjacent air conditioning zone can be suppressed. According to the twelfth aspect of the present invention, the predetermined time is substantially equal to the time required for the blowing direction of the conditioned air to exceed the limit, enter an adjacent air conditioning zone, and return to the limit again. doing. According to the thirteenth aspect of the present invention, the position at which the blowing state changing means is stopped or decelerated is set near a restriction point for restricting the direction of air-conditioning air blowing to an adjacent air-conditioning zone.

According to the fourteenth aspect of the present invention, when the occupant operation determining means determines that the occupant has operated the blow state changing means, the current state of the blow state changing means detected by the blow state detecting means is provided. By stopping the swinging motion of the blowing state changing means at or near the position until a predetermined time has elapsed, the air conditioning state desired by the occupant can be reflected in the control.
According to the invention as set forth in claim 15, when the air-conditioning wind blows toward the occupant, the larger the air-conditioning load, the longer the predetermined time for stopping the swinging motion of the blow-off state variable means is set, And, when the blowing direction of the conditioned air is in the direction of removing the occupant, the larger the air conditioning load is, the shorter the predetermined time for stopping the swinging motion of the blowing state changing means is set.
The occupant does not feel hot during cooling or the occupant does not feel cold during heating, so that discomfort of the occupant can be suppressed. In addition, when the air-conditioning air blowing direction is the direction toward the occupant, the smaller the air-conditioning load, the shorter the predetermined time for stopping the swinging motion of the blowing state changing means, and the direction of the air-conditioning air blowing away from the occupant. In the case of, the smaller the air conditioning load, the longer the predetermined time for stopping the swinging motion of the blowing state changing means is, so that the occupant does not feel cold during cooling or the occupant does not feel hot during heating. Discomfort can be suppressed.

According to the sixteenth aspect of the present invention, when it is detected that the blowing state variable means has moved more than the movement amount expected from the operation speed of the actuator, the occupant operates the blowing state variable means. The decision is made.
Further, according to the seventeenth aspect of the invention, when it is detected that the blowing state variable means has moved out of the predetermined swing range, it is determined that the occupant has operated the blowing state variable means. . Thereby, it can be determined that the occupant has operated the blowing state changing means more easily than in the invention of claim 16.

Next, the above-described steps S4 to S1
A control signal is output to the various air conditioning functional components so as to be in the air conditioning control state determined or calculated in 3 (step S14). Next, it is determined whether a predetermined control cycle time (τ) has elapsed (step S15). If the result of the determination is YES, the process returns to step S2, and if the result of the determination is NO, the control waits until the control cycle time (τ) has elapsed.

Next, the swing louver control determination by the air conditioner ECU 50 will be described with reference to FIGS. Here, FIG. 13 to FIG.
6 is a flowchart showing a swing louver control decision by the control of FIG. This flowchart is performed for each blowout state variable device of each RrFACE grill 49.

First, it is determined whether the outlet mode of the second air conditioning unit 1b determined in step S10 is the FACE mode or the B / L mode (step S2).
1). If the result of this determination is NO, the routine exits from the routine of FIG. In addition, the determination result of step S21 is YES
In the case of, it is determined whether or not it is during the cool down.
Specifically, when the outside air temperature TAM is equal to or higher than 30 ° C., and when the second air conditioning unit 1b is activated within a predetermined time (for example, 10 minutes) from the start (engine start), or when the second set temperature T
It is determined whether the second inside air temperature TR (Rr) is higher than set (Rr) by, for example, 5 ° C. or more (step S).
22). If the result of this determination is YES, the routine of FIG. 14 is started and the louvers 43, 46 are stopped (auto-stop) (step S23). After that, FIG.
Exit the routine.

If the result of the determination in step S22 is NO, the second inside air temperature TR (Rr) is reduced to a predetermined temperature α.
(For example, 30 ° C.) or more is determined (step S24). If the result of this determination is YES, the operation proceeds to step S23. Also, if the determination result of step S24 is N
In the case of O, the solar radiation amount TS is a fixed amount β (for example, 500 W
/ M ² ) or more (Step S2)
5). If the result of this determination is YES, step S2
Proceed to 3. If the result of the determination in step S25 is NO, it is determined whether or not the solar radiation left-right angle is equal to or greater than a certain angle γ (for example, 60 °) (step S26). If the result of this determination is YES, the operation proceeds to step S23. Also, if the determination result in step S26 is NO, FIG.
The routine of 5 is started, and the louvers 43 and 46 are automatically swung (step S27). Thereafter, the process exits the routine of FIG.

Next, when the routine of FIG. 14 is started, the automatic stop position θc of the louvers 43 and 46 as previously described (for example, the initial setting) is read from a RAM or the like (stop position command means: step S31). Next, the louver motors 43a, 46 are stopped so that the louvers 43, 46 stop at the auto stop position θc read in step S31, that is, at a position where the occupants of the middle and rear seats are in the direction of blowing the conditioned air.
a is controlled (step S32).

Next, during the automatic stop, that is, while the operation of the louver motors 43a and 46a is stopped, the detected angle (current position) θs of the louver 43 in the left and right direction detected by each potentiometer 97 is read from the auto stop position (step S31). (Stop position) θc is determined. Further, it is determined whether or not the vertical detection angle (current position) θs of the louver 46 detected by each potentiometer 98 is different from the auto stop position (stop position) θc read in step S31 (step S33). If the result of this determination is NO, the routine exits from the routine of FIG.

Further, the determination result of step S33 is YES.
In the case of, the auto stop position θ of the louvers 43 and 46

The detected angle θs of the louvers 43 and 46 detected at 98 is stored as the automatic stop position θc. That is, the auto stop position θc is rewritten (stop position correcting means,
Stop position storage means: Step S34). Next, Louver 4
The center position θc of the automatic swing in steps 3 and 46 is corrected.
Specifically, the detection angles θs of the louvers 43 and 46 detected by the potentiometers 97 and 98 are stored as the center positions of the automatic swing. That is, the center position θc of the auto swing is rewritten (center position correcting means, center position storing means: step S35). Thereafter, the process exits the routine of FIG.

On the other hand, when the routine of FIG. 15 is started, the center position θc of the automatic swing as in the previous time (for example, the initial setting) is read (center position instruction means: step S4).
1). Next, the center position θc read in step S41
Is determined (target swing range determining means: step S42). Next, the louvers 43 and 46 are set in the automatic swing range around the center position θc as in the previous time (for example, the initial setting), that is, around the position where the conditioned air is blown out to the middle and rear seats. The louver motors 43a and 46a are controlled so as to swing (for example, 120 ° reciprocation) (step S4).
3). Next, the target louver angles (target positions) θn of the louvers 43, 46, which are predicted from the operating speeds of the louver motors 43a, 46a, are calculated (target position determining means: step S44). Specifically, when the swing speed of the louvers 43, 46 is a constant speed (for example, 10 ° / sec), FIG.
If the control cycle time of the routine of No. 5 is 1 second, for example, 1
Since the 0 ° louvers 43 and 46 will swing,
The target louver angle θn after one second is expressed by the ｛previous target position (θ
n) + 10 °.

Next, during the automatic swing, that is, during the operation of the louver motors 43a and 46a, the detection angle (current position) θs of the louver 43 in the left-right direction detected by each potentiometer 97 is determined in step S44. It is determined whether or not the angle is different from the target louver angle θn. Also, the vertical detection angle (current position) θs of the louver 46 detected by each potentiometer 98 is determined in step S4.
It is determined whether the target louver angle θn is different from the target louver angle θn determined in step S4 (step S45). If the result of this determination is NO, the routine exits from the routine of FIG.

In addition, the decision result in the step S45 is YES.
In the case of, the auto stop position θ of the louvers 43 and 46

The detected angle θs of the louvers 43 and 46 detected at 98 is stored as the automatic stop position θc. That is, the auto stop position θc is rewritten (stop position correcting means,
Stop position storage means: Step S46). Next, Louver 4
The center position θc of the automatic swing in steps 3 and 46 is corrected.
Specifically, the detection angles θs of the louvers 43 and 46 detected by the potentiometers 97 and 98 are stored as the center position θc of the automatic swing. That is, the center position θc of the automatic swing is rewritten (center position correcting means, center position storing means: step S47). After that, FIG.
Exit the routine.

[Operation of First Embodiment] Next, the operation of the vehicle air conditioner of the present embodiment will be briefly described with reference to FIGS.

For example, when the outlet mode of the first air-conditioning unit 1a is the FACE mode (B / L mode may be used), the air is sucked into the first air-conditioning duct 2a from the inside air inlet 6a by the action of the first blower 4a. After the inside air is cooled to, for example, about 4 ° C. by the first evaporator 10a, the first heater core 13 is turned on in accordance with the opening of the first A / M door 15a.
The amount of air passing through “a” is adjusted, and the conditioned air has an optimum temperature according to the first set temperature Tset (Fr) set by the occupant on the front seat side. Thereafter, the conditioned air (cool air) is supplied to the plurality of front seats F opened at the most downstream end of the first air conditioning duct 2a.
The air is blown out from the ACE air outlet 21a into the first air conditioning zone on the front seat side in the passenger compartment of the vehicle 400. In particular, cold air
It is blown out toward the head and chest of the occupant on the front seat side in the air conditioning zone.

On the other hand, when the outlet mode of the second air conditioning unit 1b is the FACE mode (B / L mode), the second blower 4 is operated in the same manner as the first air conditioning unit 1a.
b from the inside air inlet 6b to the second air conditioning duct 2
After the inside air sucked into the inside b is cooled to, for example, about 4 ° C. by the second evaporator 10b, the second A / M door 15
The air amount passing through the second heater core 13b is adjusted according to the opening degree of the second seat b, and the second seat set by the occupants on the middle seat side and the rear seat side.
The conditioned air has an optimum temperature according to the set temperature Tset (Rr). Thereafter, the conditioned air (cool air) is supplied to the plurality of middle seats and the rear seats F which are opened at the most downstream end of the second air conditioning duct 2b.
The air is blown out from the ACE air outlets 31b and 32b into the second air conditioning zone on the rear seat side of the vehicle 400. In particular, the cool air is blown toward the occupant's head and chest on the middle seat side and the rear seat side in the second air conditioning zone.

Here, when the air-conditioning state in the second air-conditioning zone on the middle seat side and the rear seat side of the cabin of the vehicle 400 is at the time of cool-down or when there is solar radiation, FIGS. As shown, the middle and rear seat FACE outlets 31b, 3b
The louver 43 is set at the initially set auto stop position (initial setting position) in order to locally (spot-like) the conditioned air blown out from 2b to the occupants on the middle and rear seat sides.
After the 46 is driven, the louvers 43 and 46 stop. The blowing direction of the conditioned air at this time is indicated by an arrow at the time of initial setting in FIG. 16 and by an arrow in FIG. However, as shown in FIG. 16, the occupant on the middle seat side turns the middle seat 402 by 180 ° to be in a rotating facing state, or the occupant on the rear seat side has the rear seat 403.
To the rear side of the vehicle 400 or the like,
After the above operation, the direction in which the louvers 43 and 46 faced, that is, the air-conditioning air blowing direction determined by the initial setting and the middle seat side,
The position of the rear occupant may be shifted.

In this case, the occupant on the middle seat side is louver 4
By directly touching the louvers 43 and 46 toward the user by touching the louvers 43 and 46, the blowing direction of the conditioned air blown out from the middle seat side FACE air outlet 31b can be changed by the user (in the direction of the arrow after the sheet is moved in FIG. 16). ). In addition, the occupant on the rear seat side touches the louvers 43 and 46 directly and turns the louvers 43 and 46 toward himself, as shown in FIG.
The blow direction of the conditioned air blown from the middle and rear seat FACE outlets 31b and 32b is directed toward the user (the direction indicated by the black dot arrow in FIG. 16).

As described above, the occupants of the middle and rear seats operate the louvers 43 and 46, and
When the automatic stop 46 is set, the louver motor 43
Despite the stop of the operations of the potentiometers a and 46a, the detection angles of the potentiometers 97 and 98, that is, the current positions of the louvers 43 and 46 (output signals of the potentiometers)
Is changed by the air conditioner ECU 50. At this time, the air conditioner ECU 50 determines that the positions of the occupants on the middle and rear seats are the positions after the movement of the seat, and the auto stop positions and the center positions of the auto swing of the louvers 43 and 46 stored in advance. Is corrected to the detection angle detected this time and stored.

Therefore, when the second air-conditioning unit 1b is operating in a steady state (for example, when the second inside air temperature is approaching the second set temperature) from the above-described state at the time of cooling down or when there is solar radiation. Even if the air-conditioning state changes to a state where there is no sunshine and the louvers 43 and 46 are switched to a swing mode in which the louvers 43 and 46 are swung at a predetermined louver angle, the louvers 43 and 46 directed by the occupants on the middle seat side and the rear seat side. (The center position of the auto swing) as shown in FIG.
As shown in (1), the louvers 43, 46 swing in a predetermined swing range (for example, 120 ° reciprocation) around the rewritten center position (the broken line position in FIG. 17). The corrected auto stop positions of the louvers 43 and 46 and the center position of the auto swing are updated in both the vertical and horizontal directions. Thereafter, when the louvers 43 and 46 are automatically stopped so as to be directed locally (in a spot manner) to the occupants on the middle seat side and the rear seat side at the time of cool down or when there is solar radiation, the corrected auto stop position is targeted. Controlled.

On the other hand, the occupants of the middle and rear seats are louvers 4.
16 and FIG. 17 when the louvers 43 and 46 are operated in the automatic swing mode.
As shown in (a) and (b), the initially set swing range means that the swing range is out of the ideal swing range, so that correction is performed. Also in this case, the louver 43,
The automatic stop position and the central position of the automatic swing at 46 are updated in both the vertical and horizontal directions. Here, when the occupants of the middle and rear seats operate the louvers 43 and 46, and the swing ranges of the louvers 43 and 46 are significantly shifted from the initially set swing ranges,
A louver angle that should not be detected during the automatic swing is detected. Therefore, it can be easily detected that the air conditioner ECU 50 operates the louvers 43 and 46 by the occupants on the middle and rear seats directly touching the louvers 43 and 46.
At this time, the air conditioner ECU 50 stores the detected angle θs detected this time as the center position of the auto swing, assuming that the occupants on the middle seat side and the rear seat side are located outside the auto swing range, and stores the center position. Correct so that it swings to the center. Thereafter, the air-conditioning state in the second air-conditioning zone changes, and the air-conditioning air is directed locally (spot-like) to the occupants on the middle and rear seats, such as during cool-down or when there is sunlight. When the control is desired, the corrected center position is controlled as the automatic stop position.

On the other hand, when the occupants on the middle and rear sides operate within the swing range of the automatic swing, the operation becomes complicated. The reason is that the swing speeds of the louvers 43 and 46 (operating speeds of the louver motors 43a and 46a) are constant speeds, so that the louvers 43 and 46 swinging in a reciprocating swing range of 120 ° once for 12 seconds, for example. Assuming that the air conditioner ECU 50 is swinging, the air conditioner ECU 50
A potential change of twice is detected each time the position is detected at positions 3 and 46. Thus, when it is detected that the swing position of the louvers 43, 46 deviates from the target position θn predicted from the operating speed of the louver motors 43a, 46a, that is, based on the detection angle θs previously detected by the potentiometers 97, 98, When a large change of 10 ° or more is detected, it can be clearly determined that the occupants on the middle seat side and the rear seat side have operated (in the case of the air conditioner ECU 50 detecting five times per second). Therefore, it is determined that the detected angle θs detected this time is the position where the occupants on the middle and rear seats are located, and the detected angle θs is rewritten as the center position of the auto swing, and the rewritten center position is set as the center. Is controlled to swing in a predetermined swing range. Thereafter, the air-conditioning state in the second air-conditioning zone changes, and the air-conditioning air is directed locally (spot-like) to the occupants on the middle and rear seats, such as during cool-down or when there is sunlight. When control is desired, control is performed with the corrected center position of the auto swing (= auto stop position) as a target.

[Effects of the First Embodiment] As described above, the seat slide for largely moving the rear seat 403 in the front-rear direction, the rotating facing seat for rotating the middle seat 402 by 180 °,
Even in the case of a vehicle 400 capable of arranging a plurality of seats, such as an all-flat seat that fully reclines all seats, the occupants on the middle and rear seats are louvers 4.
The air conditioner ECU 50 detects that the louvers 43 and 46 have been operated by directly touching the radiators 3 and 46, so that it is easy to correct the target blowing direction of the conditioned air according to the position of the occupant on the middle and rear seats. Can be done. As a result, if the seat arrangement of the middle seat 402 and the rear seat 403 is changed, even if the positions of the occupants on the middle seat and the rear seat are greatly deviated from the initial setting positions, the stored auto stop position and the stored auto stop position are not changed. Since the center position of the auto swing is rewritten to the position after the seat is moved, the FACE outlets 31b and 32b on the middle and rear seat sides after the seat is moved.
The direction of the conditioned air blown out from b does not remove the occupants on the middle seat side and the rear seat side. Therefore, even if the positions of the occupants on the middle and rear seats are significantly deviated from the initial setting positions, the direction of the conditioned air blown out from the FACE outlets 31b and 32b on the middle and rear seats is changed. By going to, the cooling feeling of the occupant can be dramatically improved. Further, since it is not necessary to add a dedicated sensor for detecting the positions of the middle and rear occupants, the number of parts is reduced, and the product price of the entire vehicle 400 can be reduced.

The control signal is output to the servo motors 17 and 18 so that the A / M opening degree SW (Dr) and the A / M opening degree SW (Pa) determined in (1) (step 180). Next, a control signal is output to the servomotors 28, 29, and 39 so as to be in the outlet mode determined in step 140 (step 190). Next, a control signal is output to the louver motors 43a and 46a so that the blowing direction, the blowing position, and the swing range determined in step 150 are set (step 2).
00). Next, the control processing of step 150 will be described based on the flowchart of FIG. First, it is determined whether the outlet mode is the FACE mode or the B / L mode (step 301). If the determination result is NO, the louver direction is set so that the side louvers 43 and 46 are directed to the nearby side windows for the purpose of defogging the side windows and cutting the cold radiation by blowing the conditioned air to the side windows. (Step 3
02). After that, the process exits the control process of step 150.

If the decision result in the step 301 is YES.
In the case of, it is determined whether or not the timer is counting (step 303). If the result of this determination is YES, the flow proceeds to the control processing of step 314. If the result of the determination in step 303 is NO, it is determined whether or not cooling down is being performed during cooling. That is, the following equation 9
Then, it is determined whether or not the expression (10) and the expression (10) are satisfied (step 304).

## EQU9 ## 5 (degrees) <{TR-Tset (Dr)}

, And the Dr-side and Pa-side set temperatures set by the Pa-side temperature setting switches 64 and 65, respectively.

If the result of the determination in step 304 is YES, that is, if the vehicle is in a cool down state, the center louvers 43 and 46 are moved to the vicinity A (see FIG. 24) of the occupant's neck in the Dr-side and Pa-side air conditioning zones. The louver direction is determined so as to turn (fix), and the side louvers 43 and 46 are
The louver direction is determined so as to face (fix) the occupant's neck near B (see FIG. 24) in the r-side and Pa-side air conditioning zones (step 305). Thereby, the conditioned air is intensively blown out to the occupants in the Dr-side and Pa-side air-conditioning zones (local cooling). Next, it is determined whether or not the occupant has moved the center louvers 43 and 46 to, for example, C (step 306). If this determination result is NO, the center louvers 43, 46
The reference position (target position) of the swing range is set to the previous position (A) (step 307). Step 30
6 is YES, the center louver 43
The reference position (target position) of the swing range 46 is changed (corrected) to the current position (C) (blowing state correction means: step 308). Next, it is determined whether or not the occupant has moved the side louvers 43, 46 to, for example, D (step 30).
9). If this determination is NO, the side louver 4
The reference positions (target positions) of the swing ranges 3 and 46 are set to the previous position (B) (step 310). If the determination result of step 309 is YES, the reference position (target position) of the swing range of the side louvers 43, 46 is changed (corrected) to the current position (D) (blowing state correction means: step 311). .

Then, it is determined whether or not the occupant has operated the louver (step 312). If the result of this determination is NO, the control process of step 150 is exited.
If the determination result of step 312 is YES,
The count of the timer is started, and the swing of the operated center louvers 43, 46 or the side louvers 43, 46 is stopped until the predetermined time shown in FIGS. 25 (a) to 25 (c) elapses (blowing state correction means). : Step 31
3). Here, the blowout temperature on the horizontal axis of the graph of FIG. 25A indicates the target blowout temperature, the cooling water temperature, the A / M opening degree in addition to the detection values of the Dr-side and Pa-side blowout temperature sensors 94a and 94b. Calculated from the temperature after evaporation. By adding a correction time according to the inside air temperature and the amount of insolation to the reference stop time obtained in FIG. 25A, it is possible to calculate a predetermined time more suited to the occupant's warmth. The stop time after the correction is 30 minutes at the maximum and 30 seconds at the minimum. The predetermined time is set to be longer as the air-conditioning heat load (for example, the solar radiation intensity or the like) is larger when the blowing direction of the conditioned air is toward the occupant, and when the air-conditioning air blowing direction is to remove the occupant. The shorter the heat load (for example, the solar radiation intensity), the shorter the setting.

Predetermined time (stop time) = reference stop time + indoor air temperature correction time + solar radiation correction time

Next, it is determined whether or not the counting of the timer has ended. That is, it is determined whether a predetermined time has elapsed (step 314). If the result of this determination is NO, the control process of step 150 is exited. If the result of the determination in step 314 is YES, the counting of the timer is terminated, and the restriction in step 313 is released (step 315). After that, the process exits the control process of step 150. Also, if the determination result of step 304 is N
In the case of O, that is, when not being cooled down during cooling or during heating, the center and side louvers 4
3 and 46 are determined so as to swing in the swing range corresponding to the air conditioning heat load, centering on the reference position of the swing range. Here, in the initial setting, the reference position of the center louver is on the Dr side, the vicinity A of the occupant's neck in the Pa side air conditioning zone (see FIG. 24), and the reference position of the side louver is on the Dr side.
It is the vicinity B of the occupant's neck in the Pa side air conditioning zone (see FIG. 24).

Then, the swing range (swing) of the center and the side louvers 43 and 46 is determined based on the direction of solar radiation, the amount of solar radiation (intensity of solar radiation) in the Dr-side and Pa-side air-conditioning zones, and the characteristic diagram of FIG. Range) θ (Dr) and θ (Pa) are determined. Then, based on the swing range of the center and side louvers 43 and 46, the characteristic diagram of FIG. 26B, and the following equations (12) and (13), the target swing range (target swing range) shown in FIG. ) Determine θ (Dr) and θ (Pa) (step 316).

[Equation 12] θ (Dr) = θ (Dr) + α

(13) θ (Pa) = θ (Pa) + α

Next, the target swing range θ (D (D) of the center and side louvers 43 and 46 obtained in step 316 described above.
r), θ (Pa) and the swing speed of each center and side louvers 43 and 46 are calculated based on the characteristic diagrams of FIGS. 28 and 29 (step 317). For example, the center, the wider the swing range of the side louvers 43, 46, the more the center,
The swing speed of the side louvers 43 and 46 is increased to make the swing cycle constant. Next, it is determined whether or not the occupant has operated during the swing of the center louvers 43 and 46 (step 3).
18). Here, the determination of the presence or absence of the occupant operation is made according to FIG.
As shown in (a) and (b), the louver motor 43a,
It may be obtained from the difference between the operating speed of 46a (the louver swing speed) and the moving speed of the potentiometers 97 and 98,
It may be determined that the detection values of the potentiometers 97 and 98 have moved out of the current swing range. If there is a switch for moving the louver, the input of the switch may be detected.

If the decision result in the step 318 is NO, the reference position of the swing range of the center louvers 43, 46 is set to the previous position (step 319). If the determination result in step 318 is YES, the reference position of the swing range of the center louvers 43, 46 is changed (corrected) to the current position (blowing state correction means: step 32).
0). Next, it is determined whether or not the occupant has operated during the swing of the side louvers 43 and 46 (step 32).
1). If this determination is NO, the side louver 4
The reference positions of the swing ranges 3 and 46 are set to the previous positions (step 322). If the determination result of step 321 is YES, the reference position of the swing range of the side louvers 43 and 46 is changed (corrected) to the current position (blowing state correction means: step 323). Thereafter, the process proceeds to the control processing of step 312.
