[0026]
Each of these doors 17, 19, 21 serves as a blowing mode switching means, and is opened and closed in conjunction with a common actuator 22 via a link mechanism (not shown). By opening / closing the doors 17, 19, and 21, a known blowing mode is switched and set.
[0027]
Two center face outlets 24 and 25 are arranged at a substantially central portion in the vehicle left-right (width) direction on the upper side of the instrument panel (instrument panel) 23 arranged in the front part of the vehicle interior. And the side face blower outlets 26 and 27 are arrange | positioned in the vehicle side left-right direction vicinity in the upper part side of the instrument panel 23. FIG. Air conditioned air is blown through the face opening 18 to each of the face outlets 24 to 27. The air conditioning unit 10 is mounted in the inner space of the instrument panel 23 in the passenger compartment.
[0028]
And each face blower outlet 24-27 is equipped with the wind direction adjustment grille 24a-27a which can adjust the wind direction of blowing air to an up-down direction and a left-right direction, respectively. That is, the wind direction adjusting grills 24a to 27a include a plurality of vertical wind direction plates (vertical louvers) that adjust the blowing direction of the conditioned air in the vehicle left-right direction, and a plurality that adjusts the blowing direction of the conditioned air in the vehicle vertical direction. It is a well-known lattice-like structure provided with a horizontal wind direction plate (lateral louver).
[0029]
Further, the center face air outlets 24, 25 have actuators 24b for automatically swinging the vertical wind direction plates of the center wind direction adjusting grills 24a, 25a in the left-right direction of the vehicle and swinging the wind direction adjusting grills 24a, 25a in the left-right direction of the vehicle. 25b are provided. The side face outlets 26 and 27 are provided with potentiometers 26b and 27b that constitute detection means for detecting the adjustment positions of the vertical wind direction plates of the side wind direction adjusting grills 26a and 27a in the vehicle left-right direction.
[0030]
Next, the electric control unit of the present embodiment will be described. The air conditioning control device 30 is a control means configured by a microcomputer and its peripheral circuits, and the air conditioning control device 30 is a predetermined unit in the microcomputer. The operations of the actuators 11b, 15a, 22, 24b, 25b and the blower driving motor 12b are controlled by arithmetic processing based on the control program.
[0031]
The air conditioning control device 30 receives signals from various sensors that detect environmental conditions that affect the air conditioning state in the passenger compartment. Specifically, an inside air temperature sensor 31 that detects an air temperature (inside air temperature) TR in the vehicle interior, an outside air temperature sensor 32 that detects an air temperature (outside air temperature) TAM outside the vehicle interior, and the blown air temperature TE of the evaporator 13 are set. Respective signals from the evaporator temperature sensor 33 to be detected, the water temperature sensor 34 to detect the water temperature TW of the heater core 15, and the solar radiation amount TS and the solar radiation sensor 35 that detect the direction of solar radiation are input to the air conditioning controller 30. Is done.
[0032]
Here, the solar radiation sensor 35 has a plurality of solar light reception sensors arranged in the left-right direction of the vehicle, and enters the vehicle interior by determining an output difference between the plurality of solar light reception sensors by the air conditioning control device 30. The solar radiation direction can also be determined.
[0033]
The air conditioning control device 30 also receives detection signals from the potentiometers 26 b and 27 b of the side face outlets 26 and 27 and an operation signal from the air conditioning operation panel 36.
[0034]
The air conditioning operation panel 36 is disposed in the vicinity of the instrument panel 23 in the passenger compartment, and is provided with a plurality of operation members 37a to 37f that are manually operated by an occupant, and operation signals of the plurality of operation members 37a to 37f are provided. Input to the air conditioning control device 30. Specifically, the plurality of operation members include an AUTO switch 37a for setting an automatic control state of the air conditioner, a temperature setting switch 37b for setting the passenger compartment temperature to a passenger's favorite temperature TSET, and an inside / outside air mode. The inside / outside air changeover switch 37c, the blowout mode changeover switch 37d for setting the blowout mode (face, bilevel, foot, foot differential, defroster), the blower amount changeover switch 37e for setting the blower amount of the blower 12, and the center face outlet A swing switch 37f for instructing a swing operation of the wind direction adjusting grills 24a and 25a.
[0035]
Next, the operation of this embodiment will be described with reference to FIG. FIG. 2 is a control routine executed by the microcomputer of the air-conditioning control device 30. The control routine is started by turning on an ignition switch of a vehicle engine (not shown). First, in step S100, it is determined whether the swing switch 37f is on. If 37f is in the on state, the process proceeds to step S110, and a temporary swing range θ0 of the air direction adjusting grills 24a and 25a of the center face outlets 24 and 25 is calculated.
[0036]
Here, the temporary swing range θ0 is calculated based on the set temperature TSET by the occupant, the inside air temperature TR, the outside air temperature TAM, the solar radiation amount TS, and the solar radiation direction into the vehicle interior. Here, the level of the cooling heat load in the passenger compartment can be determined based on the set temperature TSET, the internal temperature TR, the external temperature TAM, and the solar radiation amount TS. Further, by determining the direction of solar radiation into the passenger compartment, it is possible to determine whether the solar radiation directly hits the occupant H.
[0037]
FIG. 3A shows the case where solar radiation is not directly applied to the passenger H and the cooling heat load in the passenger compartment is low. In this case, the swing range of the center wind direction adjusting grills 24a and 25a includes the passenger H. The provisional swing range θ0 is calculated so that a wide range, that is, θ0 = θc1 to θc2. In this example, θc1 to θc2 are maximum swing ranges of the center wind direction adjusting grills 24a and 25a.
[0038]
On the other hand, FIG. 3B shows a case where solar radiation is directly applied to the occupant H. In this case, the swing range of the center wind direction adjusting grills 24a and 25a is the face of the occupant H regardless of the cooling heat load level. The provisional swing range θ0 is calculated so as to be a spot-like narrow range centered on the portion H1, that is, θ0 = θc3 to θc2.
[0039]
Further, when it is determined that the cooling heat load in the passenger compartment is high, the swing range is centered on the face H1 of the occupant H as shown in FIG. 3B even when the solar radiation does not directly hit the occupant H. The temporary swing range θ0 is calculated so as to be a spot-like narrow range. Further, when it is determined that solar radiation does not directly hit the occupant H and the cooling heat load in the passenger compartment is low, naturally, the swing range is a wide range including the occupant H as shown in FIG. The temporary swing range θ0 is calculated so that
[0040]
In the next step S120, the vehicle left-right direction position θs of the wind direction adjusting grills 26a, 27a of the side face outlets 26, 27 is read based on the detection signals of the potentiometers 26b, 27b of the side face outlets 26, 27. .
[0041]
In the next step S130, the temporary swing range θ0 of the center wind direction adjusting grills 24a and 25a is corrected according to the side wind direction adjusting grill position θs to determine the final swing range θ1, and in step S140, the center face blowing is performed. A control signal of the final swing range θ1 is output to the actuators 24b and 25b of the outlets 24 and 25, and swing control of the center wind direction adjusting grills 24a and 25a is performed.
[0042]
In order to independently control the actuators 24b and 25b of the left and right center face outlets 24 and 25, the temporary swing range θ0 and the final swing range θ1 correspond to the left and right center face outlets 24 and 25, respectively. Of course, the calculation is performed independently.
[0043]
A specific example of the method for determining the final swing range θ1 will be described with reference to FIG. 4. FIG. 4 (a) corresponds to FIG. 3 (a), the solar radiation does not directly hit the occupant H, and This is a case where the cooling heat load in the passenger compartment is low. When the side wind direction adjustment grill position θs is a position toward the right side surface of the vehicle body (a position not facing the occupant H) θs1, the provisional swing range θ0 is not corrected and is determined as the final swing range θ1. That is, θ1 = θ0 (= θc1 to θc2).
[0044]
On the other hand, when the side wind direction adjustment grill position θs is the position θs2 toward the occupant H, the final swing range θ1 is set to the left side range of the occupant H face H1 (the range deviated from the occupant face H1). To do. That is, θ1 = θc1 to θc4. Thereby, it can prevent that the cool air from the center face blower outlet 25 directly hits the passenger | crew's H face part H1, and can prevent that the passenger | crew H's cooling feeling becomes excessive automatically.
[0045]
FIG. 4 (b) corresponds to FIG. 3 (b), and is a case where solar radiation hits the occupant H directly. When the side wind direction adjustment grill position θs is a position toward the right side surface of the vehicle body (a position that does not face the occupant H) θs1, the temporary swing range θ0 is not corrected and is used as the final swing range θ1. That is, θ1 = θ0 (= θc3 to θc2).
[0046]
On the other hand, when the side wind direction adjustment grill position θs is the position θs2 toward the occupant H, the final swing range θ1 is set to a wide range including the occupant H, that is, θ1 = θc1 to θc2. As a result, even when solar radiation directly hits the occupant H, it is possible to prevent cold air from both the center face air outlet 25 and the side face air outlet 27 from concentrating excessively on the face H1 of the occupant H. Thus, an appropriate cooling feeling can be imparted to the occupant H. In addition, since the swing operation is maintained in the range of θc1 to θc2, the feeling of fluctuation of the cold air due to the swing action can be maintained, and good cooling feeling due to the effect of the fluctuation of the cold air can be ensured.
[0047]
Further, when the occupant manually operates the side wind direction adjusting grills 26a and 27a and changes the grill position while the swing operation of the center wind direction adjusting grills 24a and 25a is performed, step S120 in FIG. In S130, by correcting the temporary swing range θ0 based on the changed grill position, the final swing range θ1 in accordance with the occupant's intention to operate can be set. Therefore, it is possible to always set the swing range θ1 following the occupant's will.
[0048]
(Second Embodiment)
In the first embodiment, only the position in the vehicle left-right direction is detected by the potentiometers 26b and 27b as the side wind direction adjustment grill position θs. However, the position in both the vehicle left-right direction and the vehicle vertical direction is detected as the side wind direction adjustment grill position θs. Is detected by a potentiometer or the like, and the contact portion of the side face blowing air with respect to the occupant is specified in more detail on the basis of both the vehicle left-right direction and the vehicle vertical direction, and the final swing range θ1 is finely adjusted accordingly. May be corrected.
[0049]
For example, when the side face blown air (cold air) hits the face H1 which is the most sensitive part to the temperature sensation, the swing range of the center face blown air (cold air) is spot-like on the face H1 of the occupant H. When concentrated, the occupant H tends to feel excessive cooling, so the swing range of the center face blowing air (cold air) is expanded.
[0050]
On the other hand, when the side face blown air (cold air) hits the chest of the occupant H, the swing range of the center face blown air (cold air) is set to the above side because it is less sensitive to the warmth than the face H1. The face blowing air (cold air) is narrower than the case where the face H1 of the occupant H is hit.
[0051]
Thereby, according to the contact | abutting site | part with respect to the passenger | crew of the side face blowing air, a more fine and suitable swing range can be set.
[0052]
(Third embodiment)
Since the contact portion of the side face blown air against the occupant changes depending on the occupant's seating position, specifically the vehicle seat position, the handle position, etc., information on the vehicle seat position, the handle position, etc. is sent to the air conditioning control device 30. The final swing range θ1 may be corrected based on the information on the seating position of the occupant.
[0053]
Thereby, the effect similar to the said 2nd Embodiment can be exhibited. Further, if the final swing range θ1 is corrected using the second embodiment and the third embodiment together, the swing range can be set more appropriately.
[0054]
(Fourth embodiment)
In the first embodiment, the center wind direction adjustment grills 24a and 25a are described as swinging only in the vehicle left-right direction. However, the center wind direction adjustment grills 24a and 25a are actuated by actuators in both the vehicle left-right direction and the vehicle vertical direction. A swing operation may be performed.
[0055]
Here, as in the second embodiment, the side wind direction adjustment grill position θs can be detected by a potentiometer or the like in both the vehicle left-right direction and the vehicle vertical direction.
[0056]
As a result, in the fourth embodiment, when the side wind direction adjustment grill position θs faces the occupant's face, the final swing range θ1 by the center wind direction adjustment grills 24a and 25a is set to the occupant's chest (occupant) in the vehicle vertical direction. The lower part of the face part) is set. Conversely, when the side wind direction adjustment grill position θs is directed toward the occupant's chest, the final swing range θ1 by the center wind direction adjustment grills 24a and 25a is set toward the occupant's face in the vehicle vertical direction.
[0057]
Thus, according to the fourth embodiment, the swing range can be set finely and appropriately in accordance with the position change of the side wind direction adjustment grill position θs.
[0058]
(Fifth embodiment)
In the first embodiment, when the solar radiation is not directly applied to the occupant H and the side heat direction adjusting grille position θs is the position θs2 toward the occupant H when the cooling heat load in the passenger compartment is low, As shown in FIG. 4A, the final swing range θ1 is the left range (θ1 = θc1 to θc4) of the face H1 of the occupant H. In the fifth embodiment, in such a case, the center The wind direction of the wind direction adjusting grills 24a and 25a is set to a range deviated from the face H1 of the occupant H as θc1 to θc4, and the swing operation of the center wind direction adjusting grills 24a and 25a is stopped.
[0059]
Therefore, the cool air from the center face outlet 25 is blown out to a range outside the face H1 of the occupant H with the air direction fixed by the center air direction adjusting grills 24a and 25a.
[0060]
Thus, the correction of the swing control state of the center wind direction adjusting grills 24a and 25a in the present invention includes not only the correction of the swing range but also the stop (cancellation) control of the swing operation itself.
