The following embodiments can be partially combined with each other as long as the combination is not particularly hindered, even if not particularly specified.

(1st Embodiment)
This embodiment will be described with reference to FIGS. The automotive air-conditioning system of the present embodiment is a system for air-conditioning the cabin of the automobile 1. The automobile 1 to which the automobile air-conditioning system is applied includes an autonomous vehicle in which an autonomous driving system performs at least a part of acceleration, steering, braking, and the like in place of an occupant, in addition to an occupant mainly performing a driving operation. Contains.

First, the automobile 1 will be described. As shown in FIGS. 1 and 2, the automobile 1 includes a ceiling member 10 that covers an upper part of a vehicle interior, a seat 11 for an occupant to sit on, and a seat for detecting a state of the seat 11. A state detector 12 is provided. Note that the front and rear arrows shown in FIGS. 1 and 2 indicate the front and rear direction DR1 of the automobile 1. 1 and 2 indicate the vertical direction DR2 of the vehicle 1.

The ceiling member 10 is a member constituting the roof of the automobile 1. The ceiling member 10 is supported by a front pillar Pa, a center pillar Pb, and a rear pillar (not shown). Specifically, the ceiling member 10 includes a roof panel 101 which is an exterior material forming a body, and a roof trim 102 which is an interior material and covers the entire inner surface of the roof panel 101. In the present embodiment, the roof trim 102 forms a ceiling portion in the vehicle interior.

The seat 11 is installed in the vehicle interior. The seat 11 has a seat cushion 111 that supports the lower body (for example, buttocks) of the occupant, a seatback 112 that supports the upper body of the occupant (for example, the back), and a headrest 113 that supports the head of the occupant. ing.

The seat 11 is configured to be slidable in the front-rear direction DR1 with respect to the floor in the vehicle compartment. That is, the seat 11 is provided with a position adjustment mechanism (not shown) that adjusts the position of the seat cushion 111 in the front-rear direction DR1.

In addition, the seat 11 is configured to be able to change from an upright state in which the seatback section 112 is upright with respect to the seat cushion section 111 to a rearwardly inclined state in which the seatback section 112 is inclined rearward more than the upright state. . That is, the seat 11 is provided with an angle adjusting mechanism for adjusting the angle of the seat back portion 112 with respect to the seat cushion portion 111 (that is, the reclining angle). Although FIG. 1 illustrates a driver seat on which a driver sits as the seat 11, the seat 11 is not limited to a driver seat. The seat 11 may be a passenger seat, a rear seat, or the like as long as the reclining angle can be adjusted.

The sheet state detection unit 12 detects the state of the sheet 11, and is configured to be able to detect whether the state of the sheet 11 is a standing state or a backward state. Specifically, the seat state detection unit 12 includes an angle sensor 121 that detects a reclining angle.

Next, the vehicle air conditioning system will be described. As shown in FIG. 1, the vehicle air conditioning system includes an air conditioner 20, an air outlet 30, an air outlet adjustment mechanism 40, a driving unit 50, and a control device 70. I have.

The air conditioner 20 is a device that draws air outside the vehicle compartment or air inside the vehicle compartment and generates conditioned air that blows out into the vehicle compartment. Although not shown, the air conditioner 20 is configured by a rear air conditioner that air-conditions the rear part of the vehicle interior. The air conditioner 20 is disposed, for example, between the interior material and the exterior material on the rear side of the automobile 1. Note that the air conditioner 20 is not limited to the rear air conditioner, but may be, for example, a seat air conditioner or a front air conditioner, or may be configured as a dedicated device independent of other air conditioners.

The air conditioner 20 includes an air conditioner case 21 forming an outer shell, and accommodates a blower 22 for generating an airflow inside the air conditioner case 21, a temperature adjusting device 23 for adjusting the temperature of the airflow generated by the blower 22, and the like. I have. Note that the temperature adjusting device 23 includes a cooler such as an evaporator and a heater such as a heater core.

Although not shown, the blower 22 is configured by an electric blower that drives a fan with an electric motor. The blower 22 is configured to be able to change the blowout amount of the conditioned air in accordance with a control signal from a control device 70 described later.

Although not shown, the temperature adjusting device 23 adjusts the temperature of the conditioned air by adjusting the air volume ratio of a cooler such as an evaporator, a heater such as a heater core, and air passing through the cooler and air passing through the heater. It consists of an adjustment unit. The temperature adjusting device 23 is configured to be able to change the blow-out temperature of the conditioned air generated according to a control signal from a control device 70 described later.

As described above, the air conditioner 20 of the present embodiment is configured to be able to change the amount and temperature of the blown conditioned air. The air conditioner 20 is connected to an air conditioner case 21 with an air conditioner duct 24 for guiding the conditioned air into the vehicle interior. As a result, the conditioned air generated by the air conditioner 20 is guided into the vehicle interior via the air conditioning duct 24.

The outlet 30 is an opening for blowing out the conditioned air generated by the air conditioner 20 into the vehicle interior. The outlet 30 is connected to the airflow downstream side of the air conditioning duct 24. The air outlet 30 is opened in the ceiling portion of the vehicle compartment so that the conditioned air is blown out toward the occupant seated on the seat 11. Specifically, the air outlet 30 is provided with a seat back portion in the vertical direction DR2 of the roof trim 102 constituting the ceiling portion of the vehicle interior so that the conditioned air is blown downward from the vicinity of the occupant's head. The area is set to overlap with 112.

The blowout adjusting mechanism 40 is provided in the blowout port 30 and adjusts a blowout range of the conditioned air blown out from the blowout port 30. Specifically, the blowout adjusting mechanism 40 includes a louver 41 having a plurality of blades 411 and a louver adjustment unit (not shown) for adjusting the angle of the louver 41. The outlet adjustment mechanism 40 can adjust the direction of the conditioned air blown from the outlet 30 in the front-rear direction DR1 by changing the angle of the louver 41 by the louver adjustment unit. The outlet adjustment mechanism 40 can adjust the spread width of the conditioned air blown out from the outlet 30 in the front-rear direction DR1 by changing the angle of the louver 41 by the louver adjustment unit.

The drive unit 50 is an actuator that drives the blow-out adjustment mechanism 40. The drive unit 50 is connected to the louver 41, and can adjust and hold the louver 41 at an arbitrary angle. The drive unit 50 is configured by an electric actuator whose operation is controlled in accordance with a control signal from the control device 70.

The vehicle air-conditioning system is capable of changing the mode of air-conditioned air blown out from the air outlet 30 by changing the angle of the louver 41 of the air outlet adjustment mechanism 40. The vehicle air-conditioning system according to the present embodiment can change the blowing mode to a normal blowing mode, a spot blowing mode, and a diffusion blowing mode.

The normal blowing mode is a blowing mode in which the conditioned air blowing range is set such that the conditioned air from the outlet 30 flows along the seat back portion 112 and hits the entire seat cushion portion 111. In the normal blowing mode, for example, as shown in FIG. 3, the angle of the louver 41 is set such that the plate surfaces of the plurality of blades 411 extend along the vertical direction DR2. In this example, the outlet range BR1 in the front-back direction DR1 near the outlet 30 is equal to the opening width of the outlet 30 in the front-back direction DR1. In the normal blowout mode, for example, as shown in FIG. 4, the conditioned air from the blowout port 30 hits the entire front portion of the body of the occupant sitting on the seat 11 in the upright state. Note that the angle of the louver 41 shown in FIG. 3 is an example, and may be set to a different angle from FIG.

The spot blowing mode is a blowing mode in which the conditioned air blowing range is set to be smaller than that in the normal blowing mode so that the conditioned air from the outlet 30 impinges on a part of the seat cushion 111. In the spot blowing mode, for example, as shown in FIG. 5, the lower end of the front blade 411 is located on the rear side of the upper end, and the upper end of the rear blade 411 is located on the rear side of the lower end. Is set to the angle of the louver 41. In this example, the outlet range BR2 in the front-rear direction DR1 near the outlet 30 is narrower than the outlet range BR1 in the normal outlet mode. In the spot blowing mode, for example, as shown in FIG. 6, the conditioned air from the air outlet 30 hits a local part (for example, a thigh) in the front part of the body of the occupant sitting on the seat 11 in the standing state. Note that the angle of the louver 41 shown in FIG. 5 is an example, and may be set to an angle different from that in FIG.

In the diffusion blowing mode, the blowing range of the conditioned air is set to be wider than that in the normal blowing mode so that part of the conditioned air from the outlet 30 also flows in front of the seat cushion 111 and behind the seat back 112. This is a blowing mode. In the diffusion blowing mode, for example, as shown in FIG. 7, the upper edge of the front blade 411 is located rearward of the lower edge, and the lower edge of the rear blade 411 is located rearward of the upper edge. Is set to the angle of the louver 41. In this example, the outlet range BR3 in the front-rear direction DR1 near the outlet 30 is larger than the outlet range BR1 in the normal outlet mode. In the diffusion blowing mode, for example, as shown in FIG. 8, part of the conditioned air from the air outlet 30 hits the entire front portion of the body of the occupant sitting on the seat 11 in the standing state, and the rest does not hit the occupant's body. Flows like so. Note that the angle of the louver 41 shown in FIG. 7 is an example, and may be set to an angle different from that in FIG.

As described above, the vehicle air-conditioning system according to the present embodiment can change the blowing range of the conditioned air by switching the blowing mode to the normal blowing mode, the spot blowing mode, and the diffusion blowing mode.

Next, the control device 70 of the automotive air conditioning system will be described with reference to FIG. As shown in FIG. 9, the control device 70 includes a computer including a processor 70a, a storage unit 70b, an input unit 70c, and an output unit 70d, and peripheral circuits thereof. The storage unit 70b of the control device 70 is configured by a non-transitional substantial storage medium.

Various detection units such as the sheet state detection unit 12 are connected to the input unit 70c of the control device 70. The input unit 70c can acquire backward information indicating the change of the seat 11 from the standing state to the backward state by connecting the sheet state detecting unit 12. In the present embodiment, the input unit 70c constitutes an acquisition unit that acquires information on the state of the sheet 11.

Although not shown, an operation panel provided with an operation switch for the air conditioner 20, a temperature setting switch for determining a set temperature in the vehicle compartment, and the like are connected to the input unit 70c. The control device 70 receives setting information of the operation panel via the input unit 70c.

各種 Various control target devices such as the air conditioner 20 and the drive unit 50 that drives the blow-out adjustment mechanism 40 are connected to the output unit 70 d of the control device 70. The output unit 70d outputs a control signal to various control target devices based on the information acquired by the input unit 70c.

The control device 70 determines the control signals of the various control target devices by calculating the information acquired by the input unit 70c by the processor 70a according to the control program stored in the storage unit 70b. The control device 70 outputs the control signal determined by the processor 70a from the output unit 70d to various control target devices.

Next, control processing executed by the control device 70 will be described with reference to FIG. The control process illustrated in FIG. 10 is executed at a predetermined cycle by the control device 70 when, for example, the operation switch of the air conditioner 20 is turned on while the ignition switch or the start switch of the automobile 1 is turned on.

制 御 As shown in FIG. 10, in step S10, control device 70 determines whether or not the blowout range of the conditioned air blown out from blowout port 30 is within a predetermined range. The predetermined range is set to a range in which the conditioned air is blown toward the entire front portion of the occupant's body when the seat 11 is in the upright state. The predetermined range is a narrow range that is smaller than the maximum range of the blowing range that can be adjusted by the blowing adjusting mechanism 40. For example, the predetermined range can be set to a range equivalent to the blowing range in the normal blowing mode.

As a result of the determination processing in step S10, when the blowout range of the conditioned air exceeds the predetermined range, in step S12, the control device 70 maintains the blowout range, the blowout air amount, and the blowout temperature of the conditioned wind in the current state. . That is, the output unit 70d of the control device 70 outputs to the drive unit 50 a control signal indicating that the blowing range of the conditioned air is maintained in the current state. Further, the output unit 70d outputs a control signal to the air conditioner 20 indicating that the blowout air volume and the blowout temperature of the conditioned air are maintained in the current state.

On the other hand, as a result of the determination processing in step S10, when the blowout range of the conditioned air is within the predetermined range, the control device 70 determines in step S14 that the sheet 11 is in the backward state based on the detection result of the sheet state detection unit 12. Is determined. Specifically, control device 70 determines whether or not the reclining angle detected by seat state detection unit 12 is an angle indicating a backward state. That is, the control device 70 acquires information on the sheet 11 from the angle sensor 121 included in the sheet state detection unit 12 with the input unit 70c, and the acquired information indicates the backward movement information indicating a change from the standing state to the backward movement state. Is determined.

If the result of the determination processing in step S14 is that the sheet 11 is not in the backward state but in the upright state, the control device 70 proceeds to step S12 and sets the blowout range, blowout air amount, and blowout temperature of the conditioned air to the current state. maintain. For example, when the blowing mode is set to the normal blowing mode, the control device 70 maintains the blowing range of the conditioned air in the blowing range in the normal blowing mode. In this case, as shown in FIG. 11, the conditioned air hits the entire front portion of the body of the occupant sitting on the seat 11 in the upright state.

Here, when the air-conditioned air blowing range is within a predetermined range, if the seat 11 changes from the upright state to the backward state, the occupant's body extends in the front-rear direction DR1, so that the conditioned air is applied to the occupant's body. Parts (eg, near the waist) are intensively blown out.

状況 In a situation where the seat 11 is changed from the standing state to the backward state, the occupant often wants to take a rest or a nap. For this reason, if the conditioned air is intensively blown to a part of the occupant's body in a situation where the seat 11 is in the backward state, the occupant cannot relax and take a rest or take a nap.

Therefore, when the air-conditioned air blowing range is within the predetermined range and the seat 11 is in the backward state, the control device 70 enlarges the air-conditioned air blowing range beyond the predetermined range. That is, as a result of the determination process in step S14, when the seat 11 is in the backward state, in step S16, the control device 70 enlarges the blowout range of the conditioned air beyond the predetermined range. In other words, the output unit 70d of the control device 70 outputs, to the driving unit 50, a control signal instructing to expand the blowing range of the conditioned air in the front-back direction DR1 when the backward information is acquired by the input unit 70c. I do.

For example, when the seat 11 changes from the standing state to the backward state, the control device 70 controls the driving unit 50 so that the blowing mode of the conditioned air is changed from the normal blowing mode or the spot blowing mode to the diffusion blowing mode.

In addition, the control device 70 controls the air-conditioning equipment so that when the seat 11 changes from the upright state to the backward state, the amount of air-conditioned air blown decreases (for example, by 20%) as compared to before the change to the backward state. 20 is controlled. That is, when the backward information is acquired by the input unit 70c, the output unit 70d of the control device 70 outputs a control signal indicating that the amount of the conditioned air to be blown is reduced to the air conditioner 20.

Further, the control device 70 controls the air conditioning so that when the seat 11 changes from the upright state to the backward state, the blowout temperature of the conditioned air increases (for example, increases by 1 to 3 ° C.) as compared to before the seat 11 changes to the backward state. The device 20 is controlled. That is, when the backward information is acquired by the input unit 70c, the output unit 70d of the control device 70 outputs to the air conditioning equipment 20 a control signal indicating that the blowing temperature of the conditioned air is to be increased.

According to these, as shown in FIG. 12, the conditioned air hits the entire front part of the body of the occupant sitting on the seat 11 in the backward state. That is, when the seat 11 changes from the upright state to the backward state, the conditioned air blown out from the air outlet 30 provided in the ceiling portion hits a wide range of the occupant's body.

As described above, in the automotive air conditioning system according to the present embodiment, when the seat 11 changes to the backward position when the blowout range of the conditioned air in the standing state of the seat 11 is a narrow range within a predetermined range, the conditioned air Is expanded in the front-back direction DR1.

According to this, when the seat 11 changes from the upright state to the backward state, the conditioned air blown out from the air outlet 30 provided in the ceiling portion easily hits a wide range of the occupant's body. That is, according to the automotive air-conditioning system of the present embodiment, it is possible to suppress the conditioned air from being intensively blown out to a part of the occupant's body when the seat 11 changes from the upright state to the backward state. . As a result, it is possible to provide the occupant seated on the seat 11 with a relaxing effect.

Specifically, when the seat 11 changes to the backward state when the blowout range of the conditioned air in the standing state of the sheet 11 is within the predetermined range, the control device 70 The drive unit 50 is controlled so that the spread width of the conditioned air expands in the front-back direction DR1. According to this, when the seat 11 falls backward, the expansion width of the conditioned air is expanded in the front-rear direction DR1 by the blowing adjustment mechanism 40, so that the conditioned air blown out from the air outlet 30 can cover a wide area of the occupant's body. Easier to hit.

Further, when the seat 11 changes to the backward position when the blowout range in the upright state of the seat 11 is within the predetermined range, the control device 70 of the present embodiment can control the outlet 30 more than before the change to the backward position. The air conditioner 20 is controlled such that the amount of conditioned air blown out from the air conditioner is reduced. According to this, when the seat 11 changes to the rearward state, the comfortable conditioned air flows into the body of the occupant, so that the relaxing effect is appropriately applied to the occupant sitting on the rearwardly seated state. To the surface.

In addition, since the air outlet 30 is provided in the ceiling portion of the automobile 1, when the seat 11 is in the backward state, the distance between the occupant and the air outlet 30 tends to be large. For this reason, it is suppressed that the conditioned air from the air outlet 30 hits the occupant's body vigorously. That is, in the automotive air conditioning system of the present embodiment, when the seat 11 is in the backward position, the conditioned air having a comfortable wind pressure easily hits the occupant's body.

Further, the control device 70 according to the present embodiment is configured such that, when the blowing range in the upright state of the seat 11 is within the predetermined range, when the seat 11 changes to the backward state, the outlet is larger than before the change to the backward state. The air conditioner 20 is controlled so that the temperature of the conditioned air blown out from 30 increases. According to this, when the seat 11 changes to the backward state, the comfortable weak cold air hits the occupant's body as air-conditioned air, so that the relaxing effect for the occupant seated on the seat 11 in the backward state is appropriate. To the surface.

Here, the present embodiment is not limited to the disclosure as the above-described vehicle air conditioning system, but can be understood as the disclosure of the control device 70 of the vehicle air conditioning system. According to the disclosure of the control device 70, the same operational effects as those of the above-described disclosure of the automobile air conditioning system can be obtained. This is the same in the following embodiments.

(First Modification of First Embodiment)
As shown in FIG. 13, the outlet 30 of the above-described first embodiment is configured such that the front wall 31 and the rear wall 32 located in the front-rear direction DR1 of the vehicle 1 simply move up and down without considering the relationship with the louver 41 in particular. It extends in the direction DR2.

In such an outlet 30, for example, in the diffusion blowing mode, the distance between the front wall surface 31 and the blade plate 411 of the louver 41 near the front wall surface 31 is reduced, and the blades of the louver 41 near the rear wall surface 32 and the rear wall surface 32. The pressure loss of the conditioned air increases due to the narrowing of the gap with the plate 411. For this reason, the pressure loss of the conditioned air generated at the air outlet 30 when the seat 11 changes from the standing state to the backward state is increased. An increase in the pressure loss of the conditioned air at the outlet 30 causes a decrease in the air conditioning efficiency. In the outlet 30 shown in FIG. 13, the pressure loss of the conditioned air is likely to increase at a portion surrounded by a dashed line.

For this reason, as shown in FIG. 14, for example, as shown in FIG. 14, the air outlet 30A is provided with the front wall surface 31A and the rear wall surface 32A so that the pressure loss of the conditioned air that may occur when the seat 11 changes to the backward state is suppressed. It is desirable that the interval is configured to be enlarged toward the downstream of the flow of the conditioned air. According to this, the pressure loss of the conditioned air when the seat 11 changes from the upright state to the backward state is suppressed, so that efficient air conditioning can be provided to the occupant.

(Second Modification of First Embodiment)
In the above-described first embodiment, an example in which the outlet 30 is set in the roof trim 102 in an area overlapping with the seat back portion 112 in the vertical direction DR2 has been described, but the invention is not limited thereto.

The air outlet 30 is located at a position in the roof trim 102 that is displaced in the width direction of the automobile 1 from a region overlapping with the seat back portion 112, as long as the air conditioned air can be blown toward the occupant seated on the seat 11. May be formed.

Specifically, as shown in FIG. 15, the outlet 30 may be formed in the roof trim 102 above the side window Ws attached to the entrance door D. For example, the air outlet 30 may be formed in the roof trim 102 in the vicinity of the installation position of a handle that assists the occupant getting on and off.

As described above, when the air outlet 30 is formed above the side window Ws in the roof trim 102, it becomes easier to apply the conditioned air to a portion of the occupant's body that is easily affected by solar radiation. It becomes easier to ensure the comfort of the occupants.

(Third Modification of First Embodiment)
In addition, if the air outlet 30 is at a position where air-conditioned air can be blown toward the occupant seated on the seat 11, the area of the roof trim 102 that overlaps the seat back portion 112 extends in the front-rear direction DR 1 of the automobile 1. It may be formed at a shifted position.

Specifically, as shown in FIG. 16, the air outlet 30 may be formed in a portion of the roof trim 102 above the front window Wf. For example, the air outlet 30 may be formed in the roof trim 102 in the vicinity of the installation position of the sun visor for protecting the occupant's eyes from light incident from the front window Wf.

As described above, when the air outlet 30 is formed above the front window Wf of the roof trim 102, it becomes easier to apply the conditioned air to a portion other than the occupant's face, thereby ensuring occupant comfort. It will be easier.

(2nd Embodiment)
Next, a second embodiment will be described with reference to FIGS. This embodiment is different from the first embodiment in that the blowout adjusting mechanism 40A is configured to swing the conditioned air in the front-rear direction DR1. In the present embodiment, portions different from the first embodiment will be mainly described, and description of the same portions as the first embodiment may be omitted.

The blowout adjusting mechanism 40A is configured to be able to swing the wind direction of the conditioned air in the front-rear direction DR1. That is, as shown in FIG. 17, the blowout adjusting mechanism 40A can swing the airflow direction in the front-rear direction DR1 by periodically changing the angle of the blade plate 411 of the louver 41. I have.

The blowout adjusting mechanism 40 </ b> A configured as described above can change the blowout range of the conditioned air blown out from the blowout port 30 by changing the swing width of the conditioned air by the louver 41. Note that the swing width is the amplitude when the air conditioning wind swings by the blowout adjusting mechanism 40A.

Specifically, as shown in FIG. 18, the blowout adjusting mechanism 40A can swing the louver 41 in a small angle θ1 range such that the blowout range of the conditioned air is within a predetermined range. ing. Hereinafter, the blowing mode in which the angle of the louver 41 is periodically changed to swing the conditioned air so that the blowing range of the conditioned air is within a predetermined range is referred to as a normal swing mode.

空調 The blowout range of the conditioned air in the normal swing mode is the same range as the blowout range in the normal blowout mode. In the normal swing mode, the conditioned air from the air outlet 30 swings, for example, as shown in FIG. 19, so as to hit the entire front portion of the body of the occupant sitting on the standing seat 11. The swing width of the louver 41 shown in FIG. 18 is an example, and may be set to a different swing width from that in FIG.

Also, as shown in FIG. 20, the blowout adjusting mechanism 40A swings the louver 41 in a range where the large angle θ2 is larger than the small angle θ1 so that the blowout range of the conditioned air is larger than a predetermined range. Has become possible. Hereinafter, a blowing mode in which the conditioned air is oscillated by periodically changing the angle of the louver 41 to make the conditioned air blowing range larger than a predetermined range is referred to as a diffusion swing mode.

In the diffusion swing mode, the blowout range in the front-back direction DR1 near the outlet 30 is expanded in the front-back direction DR1 as compared with the normal swing mode. The blowing range of the conditioned air in the diffusion swing mode is the same range as the blowing range in the diffusion blowing mode. In the diffusion swing mode, the conditioned air from the air outlet 30 fluctuates, so that, for example, as shown in FIG. 21, a part of the conditioned air from the air outlet 30 is occupied by the occupant sitting on the seat 11 in the upright state. It flows over the entire front part of the body and the rest flows so as not to hit the occupant's body. The swing width of the louver 41 shown in FIG. 20 is an example, and may be set to a different swing width from that in FIG.

As described above, the vehicle air-conditioning system according to the present embodiment can change the blowing range of the conditioned air by switching the blowing mode to the normal blowing mode, the spot blowing mode, the diffusion blowing mode, the normal swing mode, and the diffusion swing mode. It has become.

Next, control processing executed by the control device 70 of the present embodiment will be described with reference to FIG. The control process shown in FIG. 22 is executed at a predetermined cycle by the control device 70 when, for example, the operation switch of the air conditioner 20 is turned on with the ignition switch or the start switch of the automobile 1 turned on. Note that the processing of step S22 and step S24 shown in FIG. 22 is the same as the processing of step S14 and step S12 shown in FIG. 10, so that the description will be simplified.

制 御 As shown in FIG. 22, the control device 70 determines whether or not the blowout range of the conditioned air blown out from the blowout port 30 is within a predetermined range in step S20. The predetermined range is set to a blowing range in which the conditioned air is blown toward the entire front portion of the body of the occupant sitting on the seat 11 in the standing state. For example, in the normal blowing mode and the normal swing mode, It can be set to a range equivalent to the blowing range.

As a result of the determination process in step S20, when the blowout range of the conditioned air exceeds the predetermined range, in step S22, the control device 70 maintains the blowout range, the blowout air amount, and the blowout temperature of the conditioned wind in the current state. .

On the other hand, as a result of the determination processing in step S20, when the blowout range of the conditioned air is within the predetermined range, the control device 70 determines in step S24 that the sheet 11 is in the backward state based on the detection result of the sheet state detection unit 12. Is determined. That is, the control device 70 determines whether or not the information on the state of the sheet 11 acquired by the input unit 70c is backward information indicating a change from the standing state to the backward state.

If the result of the determination processing in step S24 is that the seat 11 is not in the backward state but in the upright state, the control device 70 proceeds to step S22 and sets the air-conditioning air blowing range, blowing air volume, and blowing temperature to the current state. maintain.

On the other hand, if the result of the determination processing in step S24 is that the seat 11 is in the backward state, the control device 70 determines in step S26 whether or not to swing the conditioned air. In the determination process of step S26, for example, when the blowing mode before the seat 11 changes to the backward state is the normal swing mode for swinging the conditioned air, it is determined to swing the conditioned air.

As a result of the determination processing in step S26, if the conditioned air is not to be swung, the control device 70 in step S28 expands the blowout range of the conditioned air beyond the predetermined range, reduces the blowout flow rate, and further sets the blowout temperature. To rise.

For example, when the seat 11 changes from the standing state to the backward state, the control device 70 controls the driving unit 50 so that the blowing mode of the conditioned air is changed from the normal blowing mode or the spot blowing mode to the diffusion blowing mode. The control device 70 also controls the air conditioner 20 so that when the seat 11 changes from the upright state to the backward state, the amount of air-conditioning air blown out decreases (for example, by 20%) as compared to before the seat 11 changes to the backward state. Control. Further, the control device 70 controls the air conditioning so that when the seat 11 changes from the upright state to the backward state, the blowout temperature of the conditioned air increases (for example, increases by 1 to 3 ° C.) as compared to before the seat 11 changes to the backward state. The device 20 is controlled.

Accordingly, the conditioned air hits the entire front portion of the body of the occupant sitting on the seat 11 in the backward state. That is, when the seat 11 changes from the upright state to the backward state, the conditioned air blown out from the air outlet 30 provided in the ceiling portion hits a wide range of the occupant's body.

On the other hand, as a result of the determination processing in step S26, when swinging the conditioned air, in step S30, the control device 70 expands the blowing range of the conditioned air beyond the predetermined range, reduces the blowing air volume, and furthermore, Increase the outlet temperature.

For example, when the seat 11 changes from the standing state to the backward state, the control device 70 controls the driving unit 50 so that the blowing mode of the conditioned air is changed from the normal swing mode to the diffusion swing mode. The control device 70 also controls the air conditioner 20 so that when the seat 11 changes from the upright state to the backward state, the amount of air-conditioning air blown out decreases (for example, by 20%) as compared to before the seat 11 changes to the backward state. Control. Further, the control device 70 controls the air conditioning so that when the seat 11 changes from the upright state to the backward state, the blowout temperature of the conditioned air increases (for example, increases by 1 to 3 ° C.) as compared to before the seat 11 changes to the backward state. The device 20 is controlled.

Here, when the swing width of the conditioned air is expanded in the front-rear direction DR1 by the blowing adjustment mechanism 40A, if the swing cycle of the conditioned air is the same as in the standing state, the speed of swinging the conditioned air increases. I will. This may affect the air conditioning feeling of the occupant. The swing cycle is the time required for swinging the conditioned air from one side in the front-rear direction DR1 to the other side by the blowout adjusting mechanism 40A, and the time required for the conditioned air to swing from the other side in the front-rear direction DR1 to one side. It can be interpreted as the total time required.

Therefore, the control device 70 of the present embodiment sets the swing cycle of the conditioned air to be longer in step S30 than in the case where the conditioned air is swung so that the blowing range of the conditioned air is within a predetermined range. The driving unit 50 is controlled. That is, in step S30, the control device 70 controls the driving unit 50 so that the swing cycle of the conditioned air is longer than in the normal swing mode.

Accordingly, as shown in FIG. 23, the conditioned air hits the entire front part of the body of the occupant sitting on the seat 11 in the backward state. That is, when the seat 11 changes from the upright state to the backward state, the conditioned air blown out from the air outlet 30 provided in the ceiling portion hits a wide range of the occupant's body.

Other configurations and operations are the same as those of the first embodiment. The automotive air-conditioning system according to the present embodiment can obtain the same operational effects as those of the first embodiment, which are provided by a configuration common or equivalent to that of the first embodiment.

According to the automotive air-conditioning system of the present embodiment, when the seat 11 falls backward, the swing width of the conditioned air is expanded in the front-rear direction DR1 by the blow-out adjusting mechanism 40A, so that the air-conditioning blown out from the blow-out port 30. The wind is more likely to hit a wide area of the occupant's body.

In addition, in step S30, control device 70 sets the driving unit so that the swing cycle of the conditioned air is longer than in the case where the conditioned air is swung so that the blowout range of the conditioned air is within the predetermined range. 50 is controlled. According to this, it is possible to suppress the influence on the occupant's air conditioning feeling caused by increasing the swing width of the conditioned air in the front-back direction DR1. As a result, it is possible to appropriately give the occupant a relaxing effect due to the swing of the conditioned air.

(Modification of Second Embodiment)
In the above-described second embodiment, as the determination process of step S26, the process of determining to swing the conditioned air when swinging the conditioned air before the seat 11 changes to the backward state is illustrated. However, the present invention is not limited to this.

The determination process of step S26 may be a process of determining to swing the conditioned air even if the blowing mode before the seat 11 changes to the backward state is the blowing mode in which the conditioned air is not swung. . For example, when the spot blowing mode or the normal blowing mode is continued for a long time, some occupants may feel that the air conditioning wind is troublesome. For this reason, the determination process of step S26 may be, for example, a process of determining to swing the conditioned air when the spot blowing mode or the normal blowing mode is continued for a long time. In this case, as a result of the determination processing in step S26, when swinging the conditioned air, the control device 70 sets the driving unit so that the blowing mode of the conditioned wind is changed from the spot blowing mode or the normal blowing mode to the diffusion swing mode. 50 will be controlled.

Further, the determination process of step S26 is a process of determining not to swing the conditioned air even if the blowing mode before the seat 11 changes to the backward state is the blowing mode for swinging the conditioned air. Is also good. For example, when the normal swing mode is continued for a long time, some occupants want to change their mood by changing the air-conditioning air blowing state. Therefore, the determination process of step S26 may be, for example, a process of determining not to swing the conditioned air when the normal swing mode is continued for a long time. In this case, as a result of the determination processing in step S26, if the conditioned air is not to be swung, the control device 70 controls the driving unit 50 so that the blowing mode of the conditioned air is changed from the normal swing mode to the diffusion blowing mode. Will be.

In the above-described second embodiment, an example in which the louver 41 can change the direction of the conditioned air and swing the conditioned air as the blowout adjusting mechanism 40A has been described, but the present invention is not limited to this. The blowout adjusting mechanism 40A may be configured as a swing-only mechanism that swings the conditioned air by the louver 41, for example.

In the above-described second embodiment, an example is described in which the swing cycle of the conditioned air is lengthened when the swing width of the conditioned air is expanded in the front-rear direction DR1 by the blowing adjustment mechanism 40A, but the present invention is not limited to this. When the swing width of the conditioned air is expanded in the front-rear direction DR1 by the blowing adjustment mechanism 40A, the control device 70 controls the driving unit 50 so that the swing cycle of the conditioned air does not change, for example. Good.

(Third embodiment)
Next, a third embodiment will be described with reference to FIGS. This embodiment is different from the first and second embodiments in that the blowout adjusting mechanism 40B is configured to be able to adjust the opening area of the blowout port 30 in the front-rear direction DR1. In the present embodiment, portions different from the first and second embodiments will be mainly described, and description of portions similar to those in the first and second embodiments may be omitted.

For example, when the blowout range of the conditioned air exceeds the predetermined range, the control device 70 maintains the blowout range, the blowout air amount, and the blowout temperature of the conditioned air in the current state regardless of the state of the seat 11. Further, when the seat 11 is in the upright state, the control device 70 maintains the blowout range of the conditioned air, the blowout airflow, and the blowout temperature in the current state regardless of the blowout range of the conditioned wind.

On the other hand, when the seat 11 falls backward when the blowout range of the conditioned air is within the predetermined range, the control device 70 causes the blowout range of the conditioned air to be larger than the predetermined direction and to expand in the front-rear direction DR1. To control the driving unit 50. For example, when the air conditioning air blowing range is within a predetermined range and the seat 11 falls backward, the control device 70 controls the driving unit 50 so that the blowing mode changes from the small opening mode to the large opening mode.

Other configurations and operations are the same as those of the first embodiment.
