The following description relates to an air blow control device and an air blow control method according to an embodiment of the present invention.

FIG. 1 is a block diagram showing the configuration of an air conditioner 100 including an air blow control device 1 according to an embodiment of the present invention. FIG. 2 is a diagram schematically showing a vehicle A (a left-hand drive vehicle as an example) in which an air conditioner 100 including the ventilation control device 1 is installed.

The air conditioner 100 includes a ventilation control device 1 , an HVAC (Heating Ventilation and Air Conditioning) 14 , an air outlet 15 , a louver 16 , and an actuator 17 . The ventilation control device 1 includes a control section 10, a display section 11, a mechanical operation section 12, and a flash memory 13.

The control unit 10 is configured as, for example, an LSI (Large Scale Integration), and includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The CPU of the control unit 10 includes a single processor or a multiprocessor (in other words, at least one processor) that executes a program written in the ROM of the control unit 10, and centrally controls the air conditioner 100 including the blower control device 1. to control.

The ventilation control device 1, which is an example of a computer including the control unit 10, determines each ventilation position on the time axis based on a touch operation on a predetermined operation surface, and installs the air outlet 15 of the HVAC 14 at each determined ventilation position. (An example of the air outlet of an air conditioner) A method (air blow control method) including a series of processes of controlling the direction of the wind so that the air blown out from the air conditioner is sequentially sent is executed.

According to this embodiment, the air from the air conditioner is sequentially sent to each air blowing position determined based on the touch operation. Therefore, for example, cold air or hot air does not continue to directly hit the user's body. Therefore, according to this embodiment, it is possible to provide a comfortable air-conditioned environment for the user.

In this embodiment, a vehicle-mounted ventilation control device 1 is illustrated. However, it is desirable to provide users with a comfortable air-conditioned environment even inside buildings. Therefore, the ventilation control device 1 may be installed in a place other than the vehicle (for example, a building).

The display unit 11 is a device that displays various screens including a setting screen, and includes, for example, an LCD (Liquid Crystal Display) equipped with a touch panel, an organic EL (Electro Luminescence) display, and the like.

That is, the display unit 11 is an example of an operation unit including an operation surface that accepts touch operations. The screen 11A of the display unit 11 is an example of an operation surface that accepts touch operations. Note that the operation section is not limited to being provided on the display section 11, and may be a touch pad installed at a location different from the display section 11. A touchpad is also an example of an operation unit that includes an operation surface that accepts touch operations.

The mechanical operation unit 12 is a mechanical operation unit for operating the air conditioner 100 including the blower control device 1, and includes mechanical type, capacitive non-contact type, membrane type switches, buttons, knobs, wheels, etc. Includes controls such as joysticks.

Although the details will be described later, the flash memory 13 is an example of a storage unit that stores a user and information indicating each air blowing position on the time axis in association with each other.

The HVAC 14 is an example of a heat exchange device that sends cold air or hot air into the vehicle interior. HVAC 14 has a well-known configuration. Therefore, in this embodiment, a specific explanation of the HVAC 14 will be omitted.

To summarize, for example, when the mechanical operation unit 12 is operated to turn on the power of the air conditioner 100, the compressor of the HVAC 14 is activated. As a result, the air conditioner gas is mechanically compressed from a low-temperature, low-pressure gaseous refrigerant to a high-temperature, high-pressure gaseous refrigerant (semi-liquid).

The refrigerant compressed by the compressor is sent to the condenser. The refrigerant sent to the condenser releases heat as it passes through the condenser, changing into a low-temperature, high-pressure liquid refrigerant. Impurities and the like are removed from this liquid refrigerant in a receiver, and the liquid refrigerant is expanded at once by an expansion valve, and is sent to the evaporator in the form of mist.

The atomized refrigerant sent to the evaporator is vaporized in the evaporator. Air from inside the vehicle is fed into the evaporator by a blower fan. The heat held by this air is taken away as heat of vaporization when the atomized refrigerant vaporizes. Air that has been stripped of its vaporization heat and turned into cold air is blown out from the air outlet 15 of the HVAC 14. This lowers the temperature inside the vehicle.

When the cold air coming out of the evaporator is warmed by the heater core, warm air is blown out from the air outlet 15 of the HVAC 14. This increases the temperature inside the vehicle.

In this embodiment, as an example, four air outlets 15 are installed in the vehicle interior. The air outlet 15 installed on the left side in front of the driver's seat is referred to as the "air outlet 15a." The air outlet 15 installed on the right side in front of the driver's seat is referred to as the "air outlet 15b." The air outlet 15 installed on the left side in front of the passenger seat is referred to as "air outlet 15c." The air outlet 15 installed on the front right side of the passenger seat is referred to as "air outlet 15d."

Each outlet 15 is provided with a louver 16 that defines the direction of the wind blown out from the outlet 15. An actuator 17 is mechanically connected to the louver 16 of each outlet 15 via a transmission mechanism (not shown).

The actuator 17 operates according to a drive signal input from the control section 10. The power of the actuator 17 is transmitted to the louver 16 via a transmission mechanism. This changes the direction of the louver 16. By changing the direction of the louver 16, the direction of the air from the air outlet 15 changes.

Note that each air outlet 15 is provided with a plurality of louvers 16 so that the direction of the air can be changed in various directions. Examples include multiple horizontal louvers and multiple vertical louvers. The horizontal louver is a louver that is formed to extend in the left-right direction and whose orientation is variable in the vertical direction. The vertical louver is a louver that is formed to extend in the vertical direction and whose direction is variable in the horizontal direction.

As shown in FIG. 2, an in-vehicle camera 2 is installed inside the vehicle. The in-vehicle camera 2 has an angle of view that can photograph all seats in the vehicle interior. For example, when a trigger signal is input from the ventilation control device 1, the in-vehicle camera 2 photographs the inside of the vehicle. The in-vehicle camera 2 transfers the captured image to the ventilation control device 1.

FIG. 3 is a flowchart illustrating an example of an air conditioning setting process executed by the ventilation control device 1. For example, when a predetermined operation for setting the air conditioning is performed, execution of the air conditioning setting process shown in FIG. 3 is started.

As shown in FIG. 3, the control unit 10 displays an air conditioning setting screen on the screen 11A of the display unit 11 (step S101).

FIG. 4 is a diagram showing an example of an air conditioning setting screen displayed on the screen 11A in step S101. Note that in the diagrams illustrating screen examples including FIG. 4, a hand icon indicating that the user has touched the screen 11A is appropriately attached. A symbol TP is attached to the touch position where the user touches the screen 11A. The user's touch position TP on the screen 11A is acquired as two-dimensional X and Y coordinate information. The horizontal direction of the screen 11A corresponds to the X direction, and the vertical direction of the screen 11A corresponds to the Y direction.

As shown in FIG. 4, an image (for example, an image of the dashboard, windshield, etc.) schematically showing the area in front of the front seats in the vehicle interior is displayed on the air conditioning setting screen. This image includes images 115a, 115b, 115c, and 115d that imitate the air outlets 15a, 15b, 15c, and 15d, respectively.

FIG. 5 is a diagram showing an example of screen operation by a user. The symbol T1 shown in FIG. 5 indicates the trajectory of the touch operation (in other words, the trajectory of the touch position TP) when the user slides his finger while touching the screen 11A.

As shown in FIG. 5, when a touch operation of sliding on the screen 11A is performed, the control unit 10 displays a trajectory T1 corresponding to this touch operation on the screen 11A (step S102).

The trajectory T1 is an example of a line indicating the trajectory of a touch operation. That is, when a touch operation of sliding on the screen 11A is performed, the control unit 10 operates as a line display unit 10A that displays a line indicating the trajectory of the touch operation (here, the trajectory T1) on the screen 11A.

The control unit 10 determines whether the user's finger touching the screen 11A has been removed from the screen 11A (step S103). When the user's finger is removed from the screen 11A (step S103: YES), the control unit 10 determines the shape of the trajectory T1 (step S104). Unless the user's finger is removed from the screen 11A (step S103: NO), the shape of the trajectory T1 is not determined.

Note that if a predetermined touch operation (for example, double tap) is performed after the shape of the trajectory T1 is determined, the control unit 10 may erase the trajectory T1 from the screen 11A and return to the state of waiting for a slide operation. , the shape fixed state of the trajectory T1 may be canceled. In the latter case, the user can change the shape of the trajectory T1 by, for example, touching any position on the trajectory T1 and sliding a finger.

The trajectory T1 indicates each air blowing position on the time axis to which the air blown out from the air outlet 15 is sequentially sent. That is, the control unit 10 operates as a ventilation position determination unit 10B that determines each ventilation position on the time axis based on a touch operation on the screen 11A.

The control unit 10 displays an operator at at least one position on the trajectory T1 (step S105).

FIG. 6 is a diagram showing an example of a screen displayed on the screen 11A in step S105. In the example of FIG. 6, a predetermined number (specifically, five) of operators B1 to B5 are displayed on the trajectory T1. The operators B1 to B5 may be arranged at predetermined intervals, or may not be arranged at predetermined intervals. In the example of FIG. 6, operators are displayed at the start point, end point, and each vertex of the trajectory T1.

The operator may be able to be added arbitrarily on the trajectory T1. For example, when the user touches an arbitrary position on the trajectory T1, an operator is displayed at the touched position.

In this way, the control unit 10 operates as a control display unit 10C that displays a control at at least one position on the trajectory T1.

The controls B1 to B5 are controls for setting the amount of air sent to the position in the vehicle interior corresponding to the display position. For example, the display position of the operator B2 corresponds to a position above the driver's seat. Therefore, the user can set the amount of air above the driver's seat by operating the operator B2.

The control unit 10 cyclically switches the air volume corresponding to the pressed operator in the order of off, weak, medium, and strong each time the operator is pressed.

The control unit 10 determines whether an air volume determination operation has been performed (step S106). The air volume confirmation operation may be, for example, an operation of long-pressing any position other than the trajectory T1, or a touch operation of a setting confirmation button (not shown) displayed on the screen 11A.

When the air volume determination operation is performed (step S106: YES), the control unit 10 determines the air volume at each position in the vehicle interior set according to the operation on each of the operators B1 to B5 (step S107).

In this way, the control unit 10 operates as an air volume setting unit 10D that sets the amount of air sent to the air blowing position corresponding to the display position of the operator in accordance with the operation on the operator displayed on the trajectory T1. .

The control unit 10 outputs a trigger signal to the in-vehicle camera 2 and acquires an image captured by the in-vehicle camera 2 (step S108). The control unit 10 extracts a person from the captured image, and obtains the sitting position and feature amount of the extracted person (step S109). If a plurality of people are extracted, the control unit 10 acquires the seating position and feature amount for each person. Hereinafter, the information on the seating position and the feature amount acquired in step S109 will be referred to as "occupant information."

The occupant information acquired in step S109 is an example of information about a user who is in the room where the air conditioner 100 is installed. That is, the control unit 10 operates as a user recognition unit 10E that recognizes a user who is in the room where the air conditioner 100 is installed.

The control unit 10 associates the trajectory T1 determined in step S104, the air volume determined in step S107, and the occupant information acquired in step S109, and stores them in the flash memory 13 (step S110). Hereinafter, the information stored in the flash memory 13 in step S110 will be referred to as "air conditioning setting information."

In this way, when a touch operation is performed on the screen 11A, the control unit 10 displays the user recognized by the user recognition unit 10E and information (and The air volume at each air blowing position) is stored in the flash memory 13, which is an example of a storage unit.

FIG. 7 is a flowchart showing an example of an air conditioning process executed by the ventilation control device 1. For example, when the power of the air conditioner 100 is turned on, execution of the air conditioning process shown in FIG. 7 is started.

As shown in FIG. 7, the control unit 10 outputs a trigger signal to the in-vehicle camera 2 and acquires an image captured by the in-vehicle camera 2 (step S201). The control unit 10 extracts a person from the acquired photographed image, and acquires a seating position and feature amount (i.e., occupant information) for each extracted person (step S202).

The control unit 10 searches occupant information included in the air conditioning setting information stored in the flash memory 13 for occupant information whose correlation value with the occupant information acquired in step S202 is equal to or greater than a predetermined threshold (step S203).

When occupant information for which the above-mentioned correlation value is equal to or greater than a predetermined threshold value is found (step S203: YES), the control unit 10 acquires the trajectory T1 and air volume information associated with this occupant information (step S204).

For example, assume that the air conditioning setting process shown in FIG. 3 is executed while a user U1 who is sensitive to heat is sitting in the driver's seat and a user U2 who is sensitive to cold is sitting in the passenger seat. The air conditioning setting information stored in the flash memory 13 by executing this air conditioning setting process is referred to as air conditioning setting information D.

In this case, when the air conditioning process shown in FIG. 7 is executed, the trajectory T1 and the air volume information included in the air conditioning setting information D are acquired in step S204. The information acquired here is, for example, information that reflects the preferences of the users U1 and U2, and indicates set values for the wind direction and air volume for providing a comfortable air-conditioned environment for each of the users U1 and U2.

That is, according to the present embodiment, the set values of the wind direction and air volume are acquired to provide a comfortable air-conditioned environment to each user who sits in each seat and has a different comfortable temperature.

In this way, when the information of the user recognized by the user recognition unit 10E is stored in the flash memory 13, the control unit 10 operating as the air blowing position determination unit 10B determines the trajectory T1 associated with the recognized user. (an example of information indicating each air blowing position on the time axis) and information on air volume are acquired from the flash memory 13.

The control unit 10 controls the HVAC 14 and the actuator so that the air blown out from each outlet 15 is sequentially sent to each air blowing position indicated by the trajectory T1 obtained in step S204 at the air volume obtained in step S204. Controls each section including 17. That is, in step S205, the control unit 10 controls the wind direction and air volume.

In the examples shown in FIGS. 5 and 6, the execution of the process in step S205 causes wind to be blown into the vehicle interior, as described below. Note that for convenience of explanation, the trajectory T1 is divided into four sections C1 to C4. Specifically, the section on the trajectory T1 between the operator B1 and the operator B2 is written as an interval C1. The section on the trajectory T1 between the operator B2 and the operator B3 is referred to as a section C2. The section on the trajectory T1 between the operator B3 and the operator B4 is referred to as a section C3. The section on the trajectory T1 between the operator B4 and the operator B5 is referred to as a section C4.

The section C1 includes positions from the left side of the driver's seat to the upper position of the driver's seat. Section C2 includes each position from the position to the right of the driver's seat to the position above the driver's seat. In step S205, the control unit 10 connects the air outlet 15a to each position from the left side of the driver's seat to the upper position of the driver's seat (or from the upper position of the driver's seat to the left position of the driver's seat). The louver 16 of the air outlet 15a is moved so that the air is blown out sequentially. The louver 16 of the air outlet 15b is moved so that the air blown out from the air outlet 15b is sequentially sent to each position up to the position.

Thereby, the wind blown out from the air outlets 15a and 15b is sent around the user sitting in the driver's seat.

Note that if the same air volume is set for the operators located at the start point and the end point of a section (for example, operator B1 and operator B2), the air volume in the section is constant. If different air volumes are set for the operators located at the start and end points of a section, the air volume in the section changes continuously or stepwise. For example, if the air volume is set to "weak" with controller B1 and the air volume is "strong" with controller B2, the process in which the wind direction changes from the position to the left of the driver's seat to the position above the driver's seat. The airflow gradually increases.

Section C3 includes each position from the position to the left of the passenger seat to the position above the passenger seat. Section C4 includes each position from the right side position of the passenger seat to the position above the passenger seat. In step S205, the control unit 10 connects the air outlet 15c to each position from the left side of the passenger seat to the upper position of the passenger seat (or from the upper position of the passenger seat to the left position of the passenger seat). The louver 16 of the air outlet 15c is moved so that the air is blown out sequentially. The louver 16 of the air outlet 15d is moved so that the air blown out from the air outlet 15d is sequentially sent to each position up to the position.

As a result, the air blown out from the air outlets 15c and 15d is sent around the user sitting in the passenger seat.

The trajectory T1 shown in FIGS. 5 and 6 is a trajectory that avoids the users sitting in the driver's seat and the passenger seat, respectively. By setting such a trajectory T1, the user can prevent the wind blown from the air outlet 15 from directly hitting the body, and also prevent the wind from continuing to hit the body directly. Can be done. Therefore, a comfortable air-conditioned environment can be provided for the user.

In this way, the control unit 10 operates as a wind direction control unit 10F that controls the direction of the wind so that the wind blown out from the air outlet 15 is sequentially sent to each ventilation position determined by the ventilation position determination unit 10B. do.

In addition, the control section 10 that operates as the wind direction control section 10F controls the wind direction so that the wind blown out from the air outlet 15 is sequentially sent to each ventilation position indicated by the trajectory T1 acquired by the ventilation position determination section 10B. control the orientation of

In the search process in step S203, if no occupant information whose correlation value with the occupant information acquired in step S202 is equal to or greater than a predetermined threshold is found (step S203: NO), the control unit 10 performs air conditioning control in the normal mode. (Step S206). For example, in the normal mode, the control unit 10 controls the HVAC 14 so that air is blown out from the air outlet 15 at an air volume set by a user operation. In the normal mode, the wind direction is fixed, for example.

The trajectory T1 shown in FIGS. 5 and 6 is only an example. Other trajectories T2 and T3 are illustrated in FIGS. 8 and 9, respectively.

By performing a touch operation to draw a trajectory T2 illustrated in FIG. 8, the user can set the direction of the wind from the air outlet 15 so that the air circulates within the vehicle interior. By performing a touch operation to draw a trajectory T3 illustrated in FIG. 9, the user can set the direction of the air from the air outlet 15 so that the air is sent horizontally within the vehicle interior.

The above is a description of exemplary embodiments of the invention. The embodiments of the present invention are not limited to those described above, and various modifications can be made within the scope of the technical idea of the present invention. For example, the embodiments of the present application also include appropriate combinations of embodiments exemplified in the specification or obvious embodiments.

In the above embodiment, each ventilation position is set based on the trajectory of the touch operation drawn on the screen 11A, but the present invention is not limited to this. A configuration in which each air blowing position is set based on another touch operation that does not draw a trajectory is also within the scope of the present invention.

FIG. 10 is a diagram illustrating an example of processing for setting each air blowing position based on a touch operation that does not draw a trajectory. In FIG. 10, screen examples S1 to S3 are shown.

When the user touches any position on the screen 11A (see screen example S1), the control unit 10 displays a line L1 corresponding to this touch position TP on the screen 11A. As shown in the screen example S2, the line L1 is a line that includes the touch position TP and extends in the left-right direction.

In this way, when a touch operation is performed on an arbitrary position on the screen 11A, the control unit 10 operates as a line display unit 10A that displays a line L1 including this arbitrary position on the screen 11A.

The control unit 10 displays the operators B6 to B8 on the line L1, as shown in the screen example S2. The operator B6 is displayed at the midpoint of the line L1, which is a line segment. Operators B7 and B8 are displayed at respective end points of line L1.

The user can change the shape of the line L1 by touching any of the operators B6 to B8 and sliding his finger. In the screen example S3, the user touches the operator B6 and slides it to the upper side of the screen 11A. As a result, the operator B6 moves to the upper side of the screen 11A. For example, the control unit 10 transforms the straight line L1 into a B-spline curve having control points B7, B8 and the moved control B6 as control points (see screen example S3).

In this way, the control unit 10 operating as the line display unit 10A changes the shape of the line L1 in response to a touch operation on the line L1 displayed on the screen 11A.

When the user's finger is removed from the screen 11A, the control unit 10 determines the shape of the line L1. The control unit 10 determines each air blowing position based on the line L1 whose shape has been determined, similarly to the above embodiment. In this case as well, a comfortable air-conditioned environment can be provided to the user.
