Description

  The present invention relates to a vehicle air conditioner and a vehicle air conditioning control method capable of maintaining a comfortable cooling state of a driver's seat space when cold air is supplied to a driver's seat only from a vent outlet.

As an air conditioning system for a vehicle that efficiently air-conditions the driver's seat space when the occupant is only the driver, the one disclosed in Patent Document 1 below is known.
This is a mode in which the temperature of the driver's seat space is rapidly adjusted when it is determined that the occupant is the driver only, and the outlets other than the driver's seat space among the plurality of outlets are closed, and only the driver's seat space is closed. By blowing out the conditioned air, the driver's seat space can be efficiently brought close to the set temperature.

JP, 2008-296717, A

  However, in the case where only the driver's seat space is intensively cooled, a temperature difference occurs between the driver's seat space and the surrounding space, so that unintended hot air in the vehicle compartment easily flows into the driver's seat space.

Therefore, even when the occupant is only the driver, at the time of the cooldown in which the temperature is rapidly adjusted, the entire passenger compartment is temporarily cooled so as to approach the set temperature (see FIG. 17A), and the entire passenger compartment is set. After cooling to near the temperature, it is possible to shift to the driver's seat concentrated blowout mode in which conditioned air is supplied only to the driver's seat space (see FIG. 17B).
With this configuration, it is possible to prevent unintended hot air in the vehicle compartment from reaching the driver's seat space in advance, as compared with the case where the driver's seat concentrated blowing mode is set from the initial stage.

However, in the passenger compartment, heat constantly flows in and out of the outside, so if the driver's seat concentrated blowing mode is continued, a temperature difference will eventually occur between the driver's seat space and other spaces, The driver's seat space has a relatively low temperature compared to other spaces (see FIG. 17(c)).
The relatively low temperature air in the driver's seat space has a higher specific gravity than the relatively hot air other than the driver's seat space and is easily affected by inertia.
Therefore, when the vehicle turns while the vehicle is traveling straight (see FIG. 18A), the air in the driver seat space having a relatively high specific gravity moves to a place other than the driver seat (to the opposite side to the turning direction). Therefore, warm air having a relatively low specific gravity existing around the driver's seat space temporarily flows into the driver's seat space, and the comfortable cooling state of the driver's seat space is impaired.

For example, in a right-hand drive vehicle, when turning to the left, as shown in FIG. 18(b), relatively cool air moves toward the right side of the vehicle, and relatively hot air is driven from the passenger side. It flows into the seat space. Further, when turning right, as shown in FIG. 18C, the relatively low temperature air moves to the passenger seat side, and the relatively high temperature air flows into the driver seat space from the rear of the passenger compartment.
For this reason, there is a disadvantage that the cooling state of the driver's seat space is temporarily hindered when the vehicle turns.
The inconveniences described above are the same not only when the driver's seat concentrated blowout mode is set during the cooling operation but also when the driver's seat space is set to the blowout mode in which more cool air is supplied than the passenger seat space. Can occur in

  The present invention has been made in view of the above circumstances, and during cooling operation, when the driver's seat is preferentially cooled, for example, when only the driver's seat is intensively cooled, or the passenger seat An air conditioner for a vehicle that can reduce the influence of the thermal environment around the driver's seat space even when the vehicle turns while supplying more cool air than the space to the driver's seat space. The main issue is to provide.

In order to achieve the above object, a vehicle air conditioner according to the present invention is provided, at least on the driver's seat side, at a center vent outlet provided near the center of the dashboard in the vehicle width direction and at a side of the vehicle width direction. A vehicle air conditioner having a side vent outlet and capable of supplying air to a vehicle compartment through the center vent outlet and the side vent outlet,
Vehicle turning direction detecting means for detecting the turning direction of the vehicle, driver side vent air volume adjusting means capable of adjusting the ratio of the air volume supplied to the center vent outlet and the side vent outlet, and the driver side vent air volume A control unit for driving and controlling the adjusting means,
The control unit is
At the time of cooling control, a blowing mode in which air is preferentially supplied through the center vent outlet (51a) and the side vent outlet (52a) on the driver's side (driver's seat concentrated to supply air only to the driver's seat) If the vehicle turning direction is detected by the vehicle turning direction detecting means when the blowing mode or the blowing mode in which more cool air is supplied to the driver's seat space than to the passenger seat space) Of the seat side center vent outlet and the side vent outlet, a supply air amount control means is provided for increasing the amount of air supplied from the vent outlet on the turning direction side to be larger than the amount of air supplied from the other vent outlet. It is characterized by

  The occupant is seated only in the driver's seat and cold air is supplied to the driver's seat space only, or the blowing mode is set so that the cold air supplied to the driver's seat space is more than the cold air supplied to the passenger seat space. When there is a large amount of cold air in the driver's seat space. This relatively low-temperature air has a larger specific gravity than the relatively high-temperature air, so when the vehicle turns, the relatively heavy air present near the driver's seat moves to other places than the driver's seat. However, warm air temporarily tries to flow into the driver's seat. However, according to the above-described control, when the vehicle turns, the supply air volume control means causes the supply air amount control means to change the amount of air supplied from the vent outlet on the turning direction side of the center vent outlet and the side vent outlet to the other vent outlet. Since the amount of air supplied from the outlet is larger than that of the driver's seat, even if the cool air in the driver's seat moves to a place other than the driver's seat, the amount of air supplied to the side opposite to the side where the cool air in the driver's seat moves is large. Therefore, it is possible to avoid the inconvenience that relatively high temperature air around the driver's seat flows into the driver's seat (a large change in the thermal environment of the driver's seat is suppressed, and a comfortable cooling state of the driver's seat is maintained. It will be possible to maintain).

Here, the control accompanying the turning of the vehicle described above may be always performed when the driver's seat is intensively cooled, but a driver seat temperature detecting means for detecting the temperature on the driver seat side and Further comprising a passenger seat side temperature detecting means for detecting a temperature on the passenger seat side, a driver seat side temperature detected by the driver seat side temperature detecting means, and a passenger seat side temperature detecting means detected by the passenger seat side temperature detecting means. The control by the supply air volume control means may be executed when the difference from the temperature on the passenger seat side becomes a predetermined value or more.
In such a configuration, the control by the supply air volume control means is performed only when the difference between the temperature on the driver's seat side and the temperature on the passenger's seat side exceeds a predetermined value, so that the vehicular air-conditioning system can be saved. It is possible to secure a dynamic operation while avoiding a large change in the thermal environment of the driver's seat due to the flow of cold air.

Looking specifically at the above configuration according to the form of the vehicle, in the vehicle where the driver's seat is on the right side with respect to the traveling direction,
(I) When the vehicle turning direction detection means detects that the vehicle is turning left, the supply air volume control means supplies the air volume supplied from the center vent outlet from the side vent outlet. Set more than the amount of air used.
(ii) When the vehicle turning direction detection means detects that the vehicle is turning to the right, the supply air volume control means supplies the air volume supplied from the side vent outlet from the center vent outlet. Set more than the required amount of air.

In addition, in the vehicle with the driver's seat on the left side in the traveling direction,
(I) When the vehicle turning direction detecting means detects that the vehicle is turning to the left, the supply air volume control means supplies the air volume supplied from the side vent outlet from the center vent outlet. Set more than the amount of air used.
(ii) When the vehicle turning direction detection means detects that the vehicle is turning to the right, the supply air volume control means supplies the air volume supplied from the center vent outlet from the side vent outlet. Set more than the amount of air used.

  As described above, according to the present invention, when the vehicle turns, when the blowing mode for preferentially cooling the driver's seat space is set, when the vehicle turns, the center vent outlet and the side vent on the driver side are provided. Of the air outlets, the amount of air supplied from the vent outlet on the turning direction side is made larger than the amount of air supplied from the other vent outlet, so even if the vehicle turns, the air around the driver's seat It is possible to avoid the inconvenience that relatively high temperature air flows into the driver's seat, suppress a large change in the thermal environment of the driver's seat, and maintain a comfortable cooling state of the driver's seat.

And a vent blowout portion 30 through which the air sent out toward the upper part of the vehicle compartment flows. Further, at the downstream end of the second outlet passage 7, there is formed a foot outlet 40 which is provided on the lower rear side of the air conditioning case 2 and through which the air delivered toward the lower part of the vehicle compartment flows.

  Here, as shown in FIG. 1( b) and FIG. 2( b ), the vent outlets 30 are provided on the driver seat side and the passenger seat side, respectively, and are arranged in the lateral width direction (vehicle width direction). ) Center vent outlets 31 (driver seat center vent outlets 31a, passenger seat center vent outlets 31b) and the center vent outlets 31 adjacent to the center vent outlets 31 in the lateral direction (vehicle width direction). ) Side vent outlets 32 (driver side seat side vent outlets 32a, passenger seat side vent outlets 32b).

  As shown in FIG. 2, the defrost blowout section 20 is connected to a defrost connection duct 23 for guiding air to a defrost blowout port (not shown) provided on the upper surface of the dashboard of the vehicle as shown in FIG. A defrost opening 24 for sending air to the defrost connection duct 23 is formed on the end face (upper end face).

  The center vent blow-out part 31 has a center vent blow-out port 51 (air toward the upper part near the center of the vehicle compartment in the driver's seat space) provided at the downstream end of the center vent blower part 31 provided near the center of the vehicle dashboard in the vehicle width direction. A center vent outlet 51a for the driver's seat, which is blown out, and a center vent connection duct 33 for guiding air to the center vent outlet 51b for the passenger seat, which blows air upward toward the center of the passenger compartment in the passenger seat, are connected. A center vent opening 34 (driver seat center vent opening 34a and front passenger seat center vent opening 34b) is formed in the downstream side end surface (upper end surface) for sending air to the center vent connection duct 33. In addition, the side vent outlet 32 is provided with a side vent outlet 52 (air toward the upper side toward the vehicle compartment side of the driver's seat space) provided at the downstream end of the side vent outlet 32 toward the side in the vehicle width direction of the dashboard. Is connected to a side vent outlet 52a for the driver's seat, and a side vent connection duct 35 for guiding air to the side vent outlet 52b for the passenger seat, which blows out air toward the upper side of the passenger compartment toward the side of the passenger compartment. A side vent opening 36 (a side vent opening 36a for the driver's seat and a side vent opening 36b for the passenger's seat) for sending air to the side vent connecting duct 35 is formed on the downstream side end surface (upper end surface) thereof.

  Therefore, in the vent outlet 30, the driver side vent opening 36a, the driver center vent opening 34a, the passenger center vent opening 34b, and the passenger side vent opening 36b are arranged in this order in the lateral direction (vehicle width direction). And a driver side partition 37a is formed between the driver side vent opening 36a and the driver side center vent opening 34a, and the driver side center vent opening 34a and the passenger side center vent opening 34b are formed. A central partition wall 37b is formed therebetween, and a passenger seat side partition wall 37c is formed between the passenger seat center vent opening 34b and the passenger seat side vent opening 36b.

Further, in this example, the foot blowout portion 40 is not connected to a duct, and has an end surface (lower end surface) formed with a foot opening 41 for sending air downward in the vehicle compartment.

It is adapted to be adjusted by a vent door 60 provided so as to face the 34 and the side vent opening 36. Further, the amount of air sent from the foot opening 41 is adjusted by a foot door 45 provided in the middle of the second outlet passage 7.

  The defrost door 25 is a rotary shaft 26 rotatably supported by the defrost blow-out portion 20 of the air conditioning case 2, and rotates integrally with the rotary shaft 26. The defrost door 25 extends from the rotary shaft 26. And a plate-shaped portion 27. In this example, the defrost door plate-like portion 27 is provided between the defrost blow-out portion 20 and the vent blow-out portion 30 from the position where the defrost door plate-like portion 27 comes into contact with the seat wall 2 a extending obliquely downward from the upper portion on the downstream side of the evaporator 8. -It is rotatable to a position where it abuts on the vent partition wall 2b.

  The foot door 45 includes a rotary shaft 46 rotatably supported in the vicinity of the second air outlet case 7 of the air conditioning case 2 connected to the mixing area 12, and two foot doors extending from the rotary shaft 46 in two different directions. It is configured to have plate portions 47a and 47b for use. In this example, the two foot door plate-shaped portions 47a and 47b are fixed with a phase difference that forms an obtuse angle with respect to the rotating shaft 46, and both foot door plate-shaped portions 47a and 47b are mounted on the vehicle of the air conditioning case 2. From the fully closed position where both the inner wall of the chamber side wall and the partition wall 2c defining the second outlet passage 7 are simultaneously contacted to close the second outlet passage 7, both foot door plate portions 47a and 47b are moved to the second position. It is rotatable to a fully open position which is substantially parallel to the blowout passage 7.

  In this example, as shown in FIG. 3, the vent door 60 is provided with a driver side vent door 60a and a passenger side vent door 60b which are separately rotatable. The respective vent doors 60a, 60b are rotary shafts 61a, 61b and a plurality of (two) plate-shaped portions extending in different radial directions from the rotary shafts 61a, 61b and capable of opening and closing the center vent opening 34. The center vent opening/closing portions 62a and 62b and the portion of the rotating shafts 61a and 61b where the center vent opening/closing portions 62a and 62b are formed extend in different radial directions at different portions in the axial direction of the rotating shafts 61a and 61b. It has a plurality of (two) plate-shaped portions, and has side vent opening/closing portions 63a and 63b capable of opening/closing the side vent opening 36.

The plate-shaped portion 620 includes a plate-shaped and rectangular-shaped rigid portion 621, and elastic portions 622 provided on the edges of three sides of the respective rigid portions 621 excluding the sides connected to the rotation shafts 61a and 61b. have.
The side vent opening/closing parts 63a, 63b also have two plate-shaped parts 630 extending in 180° different radial directions from the rotary shafts 61a, 61b, and each plate-shaped part 630 is plate-shaped and rectangular-shaped. The rigid portions 631 and the elastic portions 632 provided on the edges of the three rigid portions 631 excluding the sides connected to the rotating shafts 61a and 61b.
In this example, the plurality (two) plate-shaped portions 620 of the center vent opening/closing portions 62a and 62b and the plurality (two) plate-shaped portions 630 of the side vent opening/closing portions 63a and 63b have an extended diameter. The directions are the same.

The rotary shaft 61a of the driver-side vent door 60a and the rotary shaft 61b of the passenger-side vent door 60b are rotatably supported with respect to the air conditioning case 2 and are connected to each other so as to be rotatable relative to each other.
Specifically, the rotation shaft 61a of the driver side vent door 60a is rotatably supported by the side wall 37d of the vent outlet 30 that defines the driver side vent opening 36 and the driver side partition wall 37a. Further, as shown in FIG. 4, the end portion of the vent door 60b on the passenger side, which is connected to the rotary shaft 61b, has an enlarged diameter, and the enlarged portion 611 is rotatably supported by the central partition wall 37b.

  In addition, the rotary shaft 61b of the passenger seat side vent door 60b is rotatably supported by the side wall 37e of the vent outlet portion 30 that defines the passenger seat side side vent opening 36 and the passenger seat side partition wall 37c. As shown in FIG. 4, the end of the vent door 60a on the driver's side facing the end of the rotary shaft 61a rotates into the insertion hole 611a formed in the expanded diameter portion 611 of the vent door 60a on the driver's side. An insert portion 612 is formed so that it can be inserted therein, and the insert portion 612 is rotatably supported by the central partition wall 37b via the enlarged diameter portion 611.

  Then, as shown in FIG. 5A, the center vent outlet 31 has an edge 620a of the center vent opening/closing part 62a (62b) that is farthest from the rotation shafts 61a and 61b of the plate-shaped part 620 described later. The seat portion 38 is formed so as to project from the elastic portion 622 provided at the edge of the side. In addition, as shown in FIG. 5B, the side vent outlet 32 has an end side 630a of the side vent opening/closing part 63a (63b) (which is farthest from the rotary shafts 61a and 61b of the plate-shaped part 630 described later). The seat portion 39 is formed so as to project from the elastic portion 632 provided at the edge of the side.

  In such a configuration, the edge portion of the center vent opening 34 at the downstream end of the center vent blowing portion 31 is curved along the rotation trajectory of the center vent opening/closing portions 62a and 62b, and the center vent opening/closing portion 62a, A vent air volume regulating wall 300 is formed that narrows the gap between the vent air volume 62b and 62b over a predetermined rotation region. The edge of the side vent opening 36 at the downstream end of the side vent outlet 32 is curved along the rotation trajectory of the side vent opening/closing portions 61a and 61b, and is formed between the side vent opening/closing portions 61a and 61b. A vent air flow rate restricting wall 300 is formed that narrows the gap over a predetermined rotation area.

  In this example, the vent air flow control wall 300 provided at the edge of the center vent opening 34 is formed by the center vent extension portion 311 that extends along the rotational trajectory of the center vent opening/closing portions 62a and 62b. There is. In addition, the vent air flow control wall 300 provided at the edge of the side vent opening 36 is formed by the side vent extension portion 321 that extends along the rotational trajectory of the side vent opening/closing portions 63a and 63b.

  The center vent extension 311 is formed such that the inner wall of the center vent outlet 31 continuously extends, and a gap is left between the center vent opening/closing portions 62a and 62b and the end sides 620a. It is curved so as to have a small size over a predetermined rotation region. Side walls 312 standing upright from the edge of the center vent opening 34 are provided on both side surfaces of the center vent extension portion 311, and the end sides 620a of the center vent opening/closing portions 62a and 62b are extended to the center vent extension portion. When approaching 311, a large amount of unintended conditioned air is prevented from flowing from the side surfaces of the center vent opening/closing portions 62a and 62b.

  The side vent extension 321 is also formed so that the inner wall of the side vent outlet 32 extends continuously, leaving a gap between the side vent opening/closing parts 63a and 63b and the end sides 630a thereof. The gap is curved so as to have a small size over a predetermined rotation region. Side walls 322 standing upright from the edge of the side vent opening 36 are provided on both side surfaces of the side vent extension portion 321, and the side edges 630a of the side vent opening/closing portions 63a and 63b are the side vent extension portions. This prevents a large amount of unintended conditioned air from flowing from the side surfaces of the side vent opening/closing portions 63a and 63b when approaching 321.

  Here, the small size is, for example, 1 to 2 mm, and the size of the gap may be maintained at a constant size over a predetermined rotation region in order to stably obtain the effect of reducing the air volume. preferable.

Further, in this example, when the center vent extension portion 311 has the rotation starting point at the position where the center vent opening/closing portions 62a and 62b close the center vent opening 34, the vent door rotates largely from this closed position (this implementation). In the example, it is formed in a predetermined rotation region at the end of rotation in which it rotates left in FIG.
On the other hand, the side vent extension portion 321 is provided in a rotation area different from the center vent extension portion 311 in the rotation direction of the side vent opening/closing portions 63a and 63b. That is, when the side vent opening/closing portions 63a and 63b close the side vent opening 36, the side vent extension 321 is rotated from this closed position (in this embodiment, left side in FIG. 5). Then, the side edges of the side vent opening/closing portions 63a and 63b are formed in a predetermined rotation region immediately after passing the end surface of the side vent opening 36.

  The center vent connection duct 33 is formed in a shape such that the connection end 33a connected to the center vent outlet 31 does not interfere with the center vent extension 311, and is connected to the center vent outlet 31. The airtightness is not impaired when this is done. Similarly, the side vent connection duct 35 is formed in a shape such that the connection end portion 35 a connected to the side vent outlet 32 does not interfere with the side vent extended portion 321, and is connected to the side vent outlet 32. Airtightness is not impaired when it is done.

  An actuator 70 (70a, 70b) that applies rotational power is directly or to each of the rotary shafts 61 (61a, 61b) of the respective vent doors 60 (driver side vent door 60a, passenger side vent door 60b). , Are connected via a link mechanism L. The respective actuators 70 are drive-controlled based on the drive control command from the control unit 71 so as to give a desired movement to the vent door 60.

  Here, the control unit 71 includes an occupant boarding position detection sensor 72 that detects a boarding position of an occupant in a passenger compartment, a rotation direction detection sensor 73 that detects a rotation amount of a steering wheel from a predetermined position and specifies a rotation direction, a driver seat. Signals are input from various sensors such as a driver seat space temperature sensor 74 that detects the space temperature (Tdriver) and a passenger seat space temperature sensor 75 that detects the passenger seat space temperature (Tassist), and an air conditioner switch (A /C switch) and signals from an operation panel 76 equipped with a temperature setter for setting a target temperature of the passenger compartment, etc. are input and arithmetic processing is performed based on these signals to drive and control the air mix door and various mode doors. Etc. are controlled.

  In FIG. 6, an example of control operation of the vent door 60 by the control unit 71 is shown as a flowchart, and an example of control operation of the vent door will be described below based on this flowchart.

  First, the control unit 71 determines whether or not the occupant is seated only in the driver's seat by the occupant boarding position detection sensor 72 (step 100), and when the air conditioner is requested to turn on the air conditioner switch to cool the passenger compartment. Is determined (whether it is in the cooling mode) (step 102), and it is further determined whether the amount of air blown by the blower is other than the small air amount (Low) (step 104).

In these determination steps, it is determined that the occupant is seated only in the driver's seat, it is determined that the air conditioner wants to cool the passenger compartment, and it is determined that the amount of air blown by the blower is other than the small amount of air. In this case, it is determined whether or not the blowout mode is set so that the air can be blown from the vent outlet (step 106).
If it is determined in this step 106 that the blowout mode is set so that the air can be blown from the vent outlet, the following control is performed.

  First, in blowing air from the vent outlet, since there is no passenger on the passenger seat, the vent door 60b on the passenger seat side is set to the closed position to stop the supply air volume to the passenger seat side (step 108). Set the driver's seat centralized blowing mode to cool only the driver's seat space.

In the driver's seat concentrated blowing mode, only the driver's seat space is supplied with cool air to cool only the driver's seat space, so the cooling environment of the driver's seat space is irrespective of whether the vehicle is turning or not. In order to maintain the above condition, it is determined whether the vehicle is going straight or turning (step 110).
When it is determined that the amount of rotation of the steering wheel from the predetermined position is within a predetermined value and the vehicle is in a straight traveling state (a state in which the vehicle is not turning), the center vent opening 34a (center vent) on the driver side. The air flow rate (Bcenter) from the air outlet 51a) and the air flow rate (Bside) from the side vent opening 36a (side vent air outlet 52a) on the driver's side are made the same to cool the driver's seat space (step 112).

On the other hand, when the steering wheel rotates counterclockwise (counterclockwise) by a predetermined angle or more (the counterclockwise rotation amount from the predetermined position of the steering wheel becomes a predetermined value or more) and it is determined that the vehicle is turning left. As shown in FIG. 7, the air flow rate (Bcenter) from the center vent opening 34a (center vent outlet 51a) on the driver side is measured from the side vent opening 36a (side vent 52a) on the driver side. It is made larger than the blown air amount (Bside) (step 114).
That is, as shown in FIGS. 5 and 7(b), the end side 620a of the center vent opening/closing portion 62a is set to an open position out of the rotation area facing the center vent extension portion 311 and the side vent is opened. The actuator 70a is drive-controlled so as to be in an open position in which the end side 630a of the opening/closing part 63a is located in a rotation area facing the side vent extension 321.

  When the occupant is seated only in the driver's seat and the driver's seat concentrated blowout mode for cooling only this driver's seat space is set, when the vehicle turns straight from the state of FIG. Since the relatively low temperature air existing in the driver's seat space has a higher specific gravity than the relatively high temperature air in the other spaces, it moves toward the right side of the passenger compartment as the vehicle turns left, Although the warm air on the passenger side tries to temporarily flow into the driver's seat (see FIG. 18B), the amount of air blown from the center vent opening 34a (center vent outlet 51a) on the driver's side (Bcenter) is Since it is larger than the air flow rate (Bside) from the side vent opening 36a (side vent outlet 52a) on the driver's side, as shown in FIG. To avoid the inconvenience that a relatively high temperature air in the passenger seat space flows into the driver's seat by forming a so-called air curtain with the passenger seat space by the cool air blown from the center vent outlet 51a. (It is possible to suppress a large change in the thermal environment of the driver's seat and maintain a comfortable cooling state of the driver's seat).

  The control in step 114 is performed until it is detected that the rotation of the steering wheel has returned to the position at which the vehicle is traveling straight and the left turn of the vehicle is finished (step 116). When the left turn of the vehicle is finished, , The presence/absence of the conditions of steps 100 to 106 is determined again.

Further, when the steering wheel is rotated clockwise (clockwise) by a predetermined angle or more (the clockwise rotation amount from the predetermined position of the steering wheel is a predetermined value or more) and it is determined that the vehicle is turning right, As shown in FIG. 9, the air flow rate (Bside) from the side vent opening 36a (side vent outlet 52a) on the driver side is calculated as the air flow rate from the center vent opening 34a (center vent outlet 51a) on the driver side. (Bcenter) (step 118).
That is, as shown in FIG. 9B, the end side 620a of the center vent opening/closing portion 62a is set to an open position that is located in a rotation region facing the center vent extending portion 311, and the side vent opening/closing portion 63a is formed. The actuator 70a is drive-controlled so that the end side 630a of the above is located at an open position outside the rotation region facing the side vent extension 321.

  When the occupant is seated only in the driver's seat and the driver's seat concentrated blowout mode for cooling only this driver's seat space is set, if the vehicle turns straight from the state of FIG. Since the relatively low temperature air existing in the driver's seat space has a higher specific gravity than the relatively high temperature air in other spaces, when the vehicle turns right, the passenger side of the passenger compartment The warm air at the rear of the passenger compartment temporarily tries to flow into the driver's seat (see FIG. 18(c)), but the amount of air blown from the driver-side side vent opening 36a (side vent outlet 52a) Since (Bside) becomes larger than the air flow rate (Bcenter) from the center vent opening 34a (center vent outlet 51a) on the driver's side, as shown in FIG. The cold air is replenished to the part of the vehicle, and the air blown from the side vent outlets 52a pushes the air in the rear of the passenger compartment back to the rear, and the relatively high temperature air in the rear of the passenger compartment flows into the driver's seat. It is possible to avoid such inconvenience (a large change in the thermal environment of the driver's seat can be suppressed, and a comfortable cooling state of the driver's seat can be maintained).

  The control of step 118 is performed until it is detected that the rotation of the steering wheel has returned to the position at the time of straight running and the right turn of the vehicle is finished (step 120), and the right turn of the vehicle is finished. In this case, the presence or absence of the conditions of steps 100 to 106 is determined again.

In the above air conditioning control, as long as the driver's seat concentrated blowout mode is in operation, the space other than the driver's seat space has the same temperature as the driver's seat space. If the passenger compartment and the passenger compartment are at the same temperature, the cold air in the driver's seat will move and air from other spaces will flow into the driver's seat without causing any discomfort (impeding a comfortable cooling condition in the driver's seat). In such a case, the above control may be omitted.
That is, as shown in FIG. 11, for example, the difference (Δt) between the temperature of the passenger seat space (Tassist) and the temperature of the driver seat space (Tdriver) is greater than the predetermined value α before the determinations in steps 100 to 106. The control after step 100 may be performed only when it is larger.
Note that, in FIG. 11, the portions other than step 130 are the same as those in FIG.

  According to the control of FIG. 11, the control of step 114 or step 118 is performed only when the difference between the temperature of the driver's seat space and the temperature of the passenger seat space exceeds a predetermined value. It is possible to avoid a large change in the thermal environment of the driver's seat due to the flow of cold air while ensuring the power-saving operation of the air conditioner for a vehicle.

  In the above example, the vent air flow control wall 300 that controls the air flow sent out from the center vent opening 34 is extended from the edge of the center vent opening 34 along the rotation loci of the center vent opening/closing parts 62a and 62b. A vent air flow rate control wall 300 configured by the center vent extension 311 and for controlling the air flow sent out from the side vent opening 34 is provided. Although an example in which it is configured by the side vent extension portion 321 extending along the above is shown, in order to have the same function, as shown in FIG. 12, the center vent blowing portion of the center vent connection duct 33 is shown. A curved wall 331 for center vent is formed on the inner wall of the connection end 33a connected to 31 along the rotation trajectory of the opening/closing part 62a for center vent, and is connected to the side vent outlet 32 of the side vent connection duct 35. The side vent curved wall 351 may be formed on the inner wall of the connection end portion 35a along the rotation trajectory of the side vent opening/closing portion 62a.

  Here, the curved wall 331 for center vent is formed by bulging the inner wall of the connection end 33a of the connection duct 33 for center vent to the inside so as to be continuous from the inner wall of the center vent outlet 31, A gap is left between the edge side 620a of the 62a and the gap is curved so that the gap has a small size over a predetermined rotation region. Similarly, the side vent curved wall 351 is formed by bulging the inner wall of the connection end portion 35a of the side vent connection duct 35 inward so as to be continuous from the inner wall of the side vent outlet 32. A gap is left between the opening/closing portion 63a and the end side 630a, and the gap is curved so as to have a small dimension over a predetermined rotation region.

  Even in such a configuration, by rotating the mode door, as in the case where the center vent extension 311 and the side vent extension 321 are provided, the air volumes of the center vent blowing air and the side vent blowing air can be reduced. It is possible to change the ratio, and it is possible to obtain the same operational effect as when the configuration of FIG. 5 is used.

  In addition, in such a configuration, when the center vent connection duct 33 is attached to the center vent outlet 31 or the side vent connection duct 35 is attached to the side vent outlet 32, the vent air flow control wall 300 (center vent) is installed. The curved wall 331 for side and the curved wall 351 for side vent do not interfere, and the workability of assembling the center vent connection duct 33 and the side vent connection duct 35 is not impaired. In addition, the vent volume control wall 300 is formed not on the air conditioning case 2 but on the center vent connection duct 33 that guides air to the center vent outlet 51 and the side vent connection duct 35 that guides air to the side vent outlet 52. This makes it possible to adjust the air volume ratio of the air introduced to the center vent outlet 51 and the side vent outlet 52 by simply replacing the center vent connection duct 33 and the side vent connection duct 35.

  In the above example, as the vent air flow control wall 300, the center vent extension 341 is provided at the edge of the center vent opening 34, and the side vent extension 321 is provided at the edge of the side vent opening 34. In addition, a curved wall 331 for center vent is provided on the inner wall of the connection end 33a connected to the center vent outlet 31 of the center vent connection duct 33, and the side vent outlet 32 of the side vent connection duct 35 is provided. Although the example in which the curved wall 351 for side vent is provided on the inner wall of the connecting end portion 35a to be connected is shown, the extended portion may be provided at either the center vent opening or the side vent opening, or the curved wall may be provided. Adjusts the air volume ratio of the air introduced to the center vent outlet 51 and the side vent outlet 52, even if it is provided at either the connection end of the center vent connection duct or the connection end of the side vent connection duct. It is possible to do so.

  In the above configuration, the downstream end of the center vent outlet 31 or the connecting end 33a of the center vent connecting duct 33 that connects to the center vent outlet 31 and the downstream end of the side vent outlet 32 or the side vent connection. At least one location of the connection end portion 35a connected to the side vent blowing portion 32 of the duct 35 is curvedly formed along the rotation locus of the opening/closing portion (center vent opening/closing portion 62a, side vent opening/closing portion 63a), and is opened/closed. Vent air flow control wall 300 (center vent extension 311, side vent extension 321, center vent curved wall 331, side vent curved wall) that narrows the gap between the parts and the predetermined rotation region. 351) is provided to adjust the ratio of the amount of air sent from the center vent opening 34a to the amount of air sent from the side vent opening 36a, but without forming a vent air flow control wall in the air outlet or air outlet duct. The ratio of the amount of air sent from the center vent opening 34a to the amount of air sent from the side vent opening 36a may be changed.

Examples thereof are shown in FIGS. 13 and 14. In this example, the vent air flow control wall 300 is not provided, and the center vent opening/closing portion 62a and the side vent opening/closing portion 63a extend in different radial directions.
Each opening/closing part is composed of two plate-shaped parts 620, 630 extending in directions different by 180° with respect to the rotating shaft 61a, and a direction extending from the rotating shaft 61a of the center vent opening/closing part 62a, The direction in which the side vent opening/closing portion 63a extends from the rotary shaft 61a differs from the direction in which the side vent opening/closing portion 63a extends by a predetermined angle (θ). That is, with the rotation of the vent door 60, the rotation area in which the amount of air sent from the center vent opening 34 is maximized and the rotation area in which the amount of air sent from the side vent opening 36 is maximized are made different.

Further, in this example, the rotation starting point is the closing position at which the edge portion of the end of the opening/closing portion abuts the seat portions 38, 39 and closes the corresponding openings, and the opening position is rotated in the opening direction. 14), the rotation area in which the amount of air blown out from the side vent opening 36a is maximum is delayed from the rotation area in which the amount of air blown out from the center vent opening 34a is maximum.
An actuator 70a that applies rotational power is connected to the rotary shaft 61a of the vent door 60a on the driver side directly or via a link mechanism L, and the actuator 70a is driven based on a drive control command from the control unit 71. The position of the vent door 60 is controlled by controlling.
Since the other configurations are similar to those of the above-described configuration example, the same parts are designated by the same reference numerals and the description thereof will be omitted.

Even in such a configuration, the control shown in FIG. 6 is performed in the same manner, it is determined that the occupant is seated only in the driver's seat, it is determined that it is time to request cooling of the vehicle interior, and the blower sends the air. When it is determined that the air volume is other than the small air volume and the blowout mode that enables the airflow from the vent outlet is set, the airflow supplied to the passenger seat is stopped. Then, when the vehicle turns left, as shown in FIG. 15, the air flow rate (Bcenter) from the center vent opening 34a (center vent outlet 51a) on the driver side is adjusted to the side vent opening 36a on the driver side. Increase the amount of air blown from (side vent outlet 52a) (Bside) (step 114)
That is, as shown in FIG. 15( b ), the center vent opening/closing part 62 a on the driver side is set to the open position where the amount of air delivered from the center vent opening 34 a is maximum (the center vent opening/closing part 62 a is set to the center vent opening 62 a ). 34a), so that the side vent opening/closing part 63a on the driver's seat side is located at an open position deviating from the position where the air volume delivered from the side vent opening 36a is maximum (for side vent). The actuator 70a is drive-controlled so that the opening/closing part 63a is located at a position where the side vent opening 36a is narrowed down.

Further, when the vehicle turns right, as shown in FIG. 16, the air flow rate (Bside) from the side vent opening 36a (side vent outlet 52a) on the driver side is set to the center vent on the driver side. The amount of air blown from the opening 34a (center vent outlet 51a) (Bcenter) is increased (step 118).
That is, as shown in FIG. 16B, the side vent opening/closing portion 63a on the driver's seat side is set to the open position where the air volume delivered from the side vent opening 36a is maximum (the side vent opening/closing portion 63a is set to the side vent opening 36a). 36a) so that the center vent opening/closing portion 62a on the driver's seat side is an open position that deviates from the position where the air volume delivered from the center vent opening 34a is maximum (center vent). The actuator 70a is driven and controlled so that the opening/closing portion 62a is located at a position where the center vent opening 34a is narrowed.

  Therefore, even in such a configuration, when the occupant is seated only in the driver's seat and the driver's seat concentrated blowing mode is set to cool only this driver's seat space, if the vehicle turns to the left, The existing relatively low-temperature air moves toward the right side of the passenger compartment as the vehicle turns left, and the warm air on the passenger side tries to temporarily flow into the driver's seat (see FIG. 18( b)), the amount of air blown from the center vent opening 34a (center vent outlet 51a) on the driver side (Bcenter) is the amount of air blown from the side vent opening 36a (side vent 52a) on the driver side (Bside) As shown in FIG. 8(b), cold air is replenished in a portion of the driver's seat space near the center of the passenger compartment, and the cool air blown from the center vent outlet 51a creates a passenger seat space. A so-called air curtain is formed between them, which makes it possible to avoid the inconvenience that the relatively hot air in the passenger seat space flows into the driver's seat (a large change in the thermal environment of the driver's seat is suppressed, It will be possible to maintain a comfortable cooling condition.

  Also, when the vehicle turns to the right, the relatively cool air present in the driver's seat space moves to the passenger seat side of the passenger compartment, and the warm air behind the passenger compartment temporarily flows into the driver's seat. However, the air flow rate (Bside) from the side vent opening 36a (side vent outlet 52a) on the driver side is the center vent opening 34a (center vent outlet 51a) on the driver side. Since it is larger than the air flow (Bcenter) from the side vent outlet 52a, cold air is replenished to the right side portion of the driver's seat space, as shown in FIG. 10(b). The cool air blown from the air pushes back the air in the rear of the passenger compartment to the rear, avoiding the inconvenience that the relatively hot air in the rear of the passenger compartment flows into the driver's seat. It is possible to maintain the comfortable cooling condition of the driver's seat).

In the above configuration, the right-hand drive vehicle has been described, but for the left-hand drive vehicle, similar control can be performed by reversing the relationship between the left turn and the right turn in the description of FIGS. 6 and 11 described above. Can be handled with.
That is, when it is detected that the vehicle is turning to the left, the amount of air supplied from the side vent outlet on the driver side is made larger than the amount of air supplied from the center vent outlet, When it is detected that the vehicle is turning to the right, the amount of air supplied from the center vent outlet on the driver side may be made larger than the amount of air supplied from the side vent outlet.

Further, in the control of FIGS. 6 and 11 described above, in step 108, the supply air volume on the passenger side (passenger seat space) is stopped, and the driver's seat concentrated blowout that supplies air only to the driver seat side (driver seat space). Although the example in which the mode is set is shown, the same control can be adopted in the blowing mode in which the air is preferentially supplied through the center vent outlet 51a and the side vent outlet 52a on the driver's side.
For example, when the ventilation to the passenger side is completely stopped, in the evaporator (not shown) that generates the cool air, there is no ventilation in the part that supplies the cool air to the passenger side, and if there is concern about freezing of that part, Since it is necessary to avoid freezing of that portion, it is preferable to supply a small amount of air to the passenger side as well. Also, if the conditioned air supply from the passenger side is continued even with a small air flow, it can contribute to equalizing the temperature distribution in the entire passenger compartment, and even if comfort is improved, a small amount of air will also be supplied to the passenger side. Is preferably supplied. Therefore, in these cases, instead of step 108, a small amount of cool air is supplied to the passenger seat side (passenger seat space), and more cold air is supplied to the driver seat side (driver seat space) than to the passenger seat side. The blowout mode may be set (step 122), and then the control accompanied by the turning of the vehicle may be performed.

  Furthermore, the above-described control of FIGS. 6 and 11 can be performed even when the above-described air conditioning unit 1 is not used, and the same control may be performed using another conventionally known air conditioning unit. Good.
