Abstract

PROBLEM TO BE SOLVED: To provide such an air conditioner for a vehicle as can set a wind direction excellently irrespective of a body difference.SOLUTION: When the wind direction of an air-conditioning wind to be blown out from a face is set, a wind direction settable range A imitating the space of a driver seat portion is displayed on the screen of a center display 58. A wind direction settable range A is divided in a vertical direction, for example, into a lattice shape of five steps in a vertical direction and three rows in a transverse direction. A driver designates any of the sections as a position for abutting against an air conditioning wind. At this time, a body type is detected from the photographed picture image of the driver, and the sizes (the height and width sizes) of each partition are altered in accordance with the sizes detected.SELECTED DRAWING: Figure 4

Description

  The present invention relates to a vehicle air conditioner that enables adjustment of the direction of conditioned air blown from an outlet through an input operation of an input device of a passenger such as a driver.

  In a vehicle air conditioner mounted on an automobile, an adjustment plate for adjusting the air blowing direction is provided at the outlet of the conditioned air, and this adjustment plate is driven in two axial directions by an X-axis motor and a Y-axis motor. The wind direction can be adjusted by this (for example, refer to Patent Document 1). In Patent Document 1, the position of the occupant's face is detected by an infrared camera, and the wind direction is controlled so that the conditioned air does not directly hit the occupant's face.

  In recent years, in this type of vehicle air conditioner, for example, a configuration has been conceived in which an input device can be used to specify a wind direction (a position where air conditioned air is applied) with respect to a driver's seat occupant. In this configuration, as shown in FIG. 9, a wind direction settable range A simulating the space of the driver's seat is set on the screen (touch panel) 100 of the input device in a slightly vertically long rectangular shape. This wind direction settable range A is divided into, for example, a grid of 5 rows in the vertical (up and down) direction and 3 columns in the horizontal (left and right) direction. The driver can specify (select) one of the sections (one or a plurality of consecutive) as a position to which the conditioned air is applied by direct touch operation or remote operation.

JP 2003-341337 A

  However, in the conventionally considered one, the range and resolution of the section that can be specified in the wind direction settable range A are fixedly determined, so there is room for improvement as follows. That is, in FIG. 9A, the silhouette S of the occupant having a relatively large physique is superimposed on the wind direction settable range A, and the cursor C (indicated by a circle) is placed at the center (from the top 3). Assuming that the wind direction is set in the center row of the step, the wind can be applied to the passenger's neck. In this case, it is possible to specify the occupant's head, face, and neck individually.

  On the other hand, FIG. 9B shows a silhouette S of an occupant with a relatively small physique over the wind direction settable range A. In this case, it is impossible for small passengers to specify the head, face, and neck individually, and for the upper two compartments, it is not very meaningful to specify the position where the air conditioned air is applied. There will be no use. As described above, the conventional wind direction setting method has a disadvantage that the same setting cannot be performed due to the difference in the occupant's physique.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to set a wind direction of air-conditioned air, and to provide a vehicle air-conditioning device that can satisfactorily set the wind direction regardless of the physique. In offer.

  In order to achieve the above object, the vehicle air conditioner (1) according to the present invention is within a wind direction settable range of the conditioned air blown out from the air outlet (21, 22, 31, 32) toward the vehicle interior. An input device (4) capable of designating the wind direction, a wind direction control device (3, 42) for controlling the wind direction based on the designation of the wind direction in the input device (4), and a physique detection for detecting the physique of the passenger in the passenger compartment A means (56) and a change means (55) for changing contents that can be input in the wind direction designation of the input device (4) according to the physique of the occupant detected by the physique detection means (56). (Invention of claim 1)

  According to this, when a user (occupant including a driver) designates the direction of the conditioned air blown out from the air outlet (21, 22, 31, 32) toward the vehicle interior by the input device (4), The wind direction is controlled by the wind direction control device (3, 42). At this time, the physique of the occupant is detected by the physique detection means (56), and the contents that can be input in the wind direction designation of the input device (4) are changed by the change means (55) according to the detected physique of the occupant. .

  This makes it possible to change the input content so that the same setting can be made depending on whether the occupant has a large physique or a small physique. Therefore, according to the invention of claim 1, the wind direction of the conditioned air can be set, and an excellent effect that the wind direction can be set satisfactorily regardless of the difference in physique is achieved.

Can be controlled.

  The air conditioner ECU 3 includes a computer and controls the entire vehicle air conditioner 1. At this time, as shown in FIG. 1, the air conditioner ECU 3 receives signals from various sensors 53 and a setting signal from a control unit 55 (see FIG. 4) of the operation input device 4 described later. It is like that. Although not shown in detail, the various sensors 53 include an inside air temperature sensor, an outside air temperature sensor, a solar radiation sensor, a post-evaporation temperature sensor, a cooling water temperature sensor, a humidity sensor, and the like.

  The setting signal input from the control unit 55 of the operation input device 4 includes an operation mode, a set temperature, an air volume, an air outlet, a wind direction, and the like. The air conditioner ECU 3 has the software configuration and the blower motor 8 and the motors 12, 19, 20, 28, 29 based on the setting signal input from the control unit 55 and the detection signals of the various sensors 53. , 30, 38, 39, 40, each swing register 42 (vertical louver drive mechanism 47 and lateral louver drive mechanism 48), the refrigeration cycle and the heater core 16 are controlled, and the air conditioning operation is executed. At this time, as will be described later, the air conditioner ECU 3 controls each swing register 42 based on the designation of the wind direction in the operation input device 4 to obtain the designated wind direction. Accordingly, a wind direction control device is constituted by the air conditioner ECU 3, each swing register 42, and the like.

  As shown in FIG. 4, the operation input device 4 includes a control unit 55, a center display 58, a remote device 59 as a remote operation device, and the like. The air conditioner ECU 3 is connected to the control unit 55 of the operation input device 4 via an in-vehicle LAN 54 such as CAN. In the present embodiment, a camera system 56 that functions as a physique detection unit is connected to the in-vehicle LAN 54. Although not shown in detail, the camera system 56 includes a camera for photographing the driver in the driver's seat (and the passenger in the passenger seat), an image processing device for processing the photographed image data, and the like.

  The control unit 55 is configured mainly by a computer, and the center display 58 and the remote device 59 are connected to the control unit 55. The center display 58 is composed of, for example, a color liquid crystal display, and is provided at the center of the instrument panel 41 as shown in FIG. The display on the center display 58 is controlled by the control unit 55. The center display 58 displays various screens such as a map screen and a screen for control (instruction / selection) of each in-vehicle device including the vehicle air conditioner 1. Although not shown, a touch panel for operation input is also provided on the surface of the center display 58. An operation signal of the touch panel is input to the control unit 55.

  The remote device 59 is provided for the occupant to select and operate graphics (GUI) displayed on the screen of the center display 58. By the operation, the remote device 59 provides instructions to each vehicle-mounted device such as the vehicle air conditioner 1 and the like. An input operation such as selection and setting can be performed. Although detailed illustration is omitted, the remote device 59 includes, for example, an operation knob (joystick) that can be tilted and a determination switch including a push button switch. An operation signal for the decision switch is input to the control unit 55. The remote device 59 is provided, for example, at a center console (rear side of the shift lever) in the vehicle interior.

  At this time, an occupant such as a vehicle driver can set the operation mode, set the temperature, and set the air volume for the vehicle air conditioner 1 by touching the touch panel on the screen of the center display 58 or operating the remote device 59. Various settings such as selection of the outlet and setting of the wind direction can be performed. In this case, selection of the air outlet, setting of the wind direction, etc. can be performed separately on the driver's seat side and the passenger seat side.

  In the present embodiment, the driver in the driver's seat will be described as an example. However, when setting the direction of the conditioned air blown from the face outlets 21 and 22 to the driver's seat, as shown in FIG. The wind direction settable range A imitating the space of the driver's seat is set on the screen 58 in a slightly vertically long rectangular shape. The wind direction settable range A is divided into, for example, a grid of 5 rows in the vertical (up and down) direction and 3 columns in the horizontal (left and right) direction. An occupant such as a driver can set (specify) one of the sections (one or a plurality of consecutive ones) as a position to which the conditioned air is applied by operating the touch panel or a remote device.

  In setting the wind direction, the control unit 55 displays on the screen of the center display 58 a silhouette S (contour) representing the upper part from the chest of the occupant, in this case the driver, and overlays the silhouette S on the screen. Then, a grid indicating each section obtained by dividing the wind direction settable range A into five rows and three columns is displayed. In addition, the cursor C is displayed in the set wind direction area. Here, in this embodiment, the physique of the driver who is an occupant is detected, and the contents that can be input in the wind direction designation of the operation input device 4 are changed according to the detected physique of the occupant. Specifically, the pattern of the section is changed, and in this embodiment, the size (height and width dimensions) of each section is changed.

  In the present embodiment, the physique of the occupant (driver) is detected by photographing the driver with the camera system 56, and extracting the contour of the upper part from the driver's chest from the photographed image. Done. As illustrated in FIG. 5, in changing the size of the section, the entire wind direction settable range A is left as it is, and the height direction of each stage divided therein is changed according to the physique of the driver. The dimensions and dimensions in the width direction of each column are changed. In this case, the silhouette S is displayed on the wind direction setting screen so as to overlap the wind direction settable range A in a size corresponding to the physique of the actually photographed driver.

  FIG. 5A shows a case of a driver with a large physique. For example, with the driver's neck part as the center, five rows in the vertical direction and three rows in the left and right direction have equal height and width. Set by dimensions. On the other hand, FIG. 5 (b) shows the case of a driver with a fairly small physique. Again, in the vertical direction (upper and lower stages), the upper stage is about the upper stage so that the driver's neck part is in the central compartment. Each section is divided so that the height dimension is larger and the height dimension is smaller at the lower stage, and the width direction (row) is slightly smaller in the middle row and slightly larger in the left and right rows. Be changed. Accordingly, the control unit 55 functions as a changing unit.

  When the occupant designates the wind direction on such a wind direction setting screen, the control unit 55 outputs a wind direction setting signal to the air conditioner ECU 3 based on the designation operation. Then, the air conditioner ECU 3 controls each of the swing registers 42 (the vertical louver drive mechanism 47 and the horizontal louver drive mechanism 48) based on the setting signal, and from the face outlets 21, 22, 31, 32, Air-conditioning air is blown out in the designated wind direction. In addition, although demonstrated here in the driver's seat (driver | operator), the same process can be performed independently regarding a passenger | crew's passenger seat regarding wind direction setting.

  Next, the operation of the vehicle air conditioner 1 configured as described above will be described with reference to FIG. The flowchart of FIG. 6 shows the procedure of the designated section change process executed by the control unit 55 when setting the wind direction for the face outlets 21, 22, 31, and 32 in the vehicle air conditioner 1. That is, first, in step S1, it is determined whether or not there is a driver (sitting on the seat of the driver's seat). If there is a driver (Yes in step S1), in the next step S2, The driver's physique is detected.

  In this case, as described above, the physique of the driver is detected using the camera system 56 based on a photographed image obtained by actually photographing the driver in the passenger compartment with the camera. In the next step S3, it is determined whether correction, that is, a change in section, is necessary according to the detected physique of the driver. In the example shown in FIG. 5, if the driver is a relatively large physique (see FIG. 5A), there is no need to change the section (No in step S <b> 3), and the processing is ended as it is.

  On the other hand, when the detected physique is relatively small (see FIG. 5B), it is necessary to change the section (Yes in step S3). In this case, in step S4, the contents that can be input, that is, the width dimension and the height dimension of each section in the wind direction settable range A are changed, and the process ends. Thereafter, a passenger such as a driver can specify (set) the wind direction by operating the touch panel or the remote device 59 while looking at the screen of the center display 58.

  In this case, in the case of a large driver, as shown in FIG. 5 (a), by designating each section, the position where the wind is applied should be individually aimed at the head, face, neck, etc. Can do. On the other hand, even in the case of a small driver, as shown in FIG. 5 (b), the size of the section on the lower side in the wind direction setting range A is small. You can specify your head, face, neck, etc. individually. In addition, the space above the head of the user is not unnecessarily finely partitioned.

  As described above, by changing the size of the section in accordance with the physique of the occupant, it is possible to equalize the target portion and to solve the problem that the designated section becomes uselessly fine. Further, in this case, since the contour of the occupant is displayed as a silhouette S on the screen of the center display 58 so as to overlap the wind direction settable range A, the display of the silhouette S may be used as a guideline for specifying the wind direction. This makes it possible to specify the desired wind direction in an easy-to-understand manner.

  Thus, according to this embodiment, when designating the direction of the conditioned air blown out from the face outlets 21, 22, 31, and 32 into the vehicle interior, the physique of the passenger in the vehicle interior is detected and detected. The content (pattern) that can be input in the wind direction designation of the input operation device 4 is changed according to the physique of the occupant. As a result, depending on whether the occupant has a large physique or a small physique, the target position can be set in the same manner and the wind direction can be set so that fine division is not wasted. It became possible to change the size of each section into which A was divided.

  As a result, according to the present embodiment, the wind direction of the conditioned air can be set, and an excellent effect that the wind direction can be set satisfactorily regardless of the difference in the occupant's physique can be obtained. . In particular, in the present embodiment, the camera system 56 is provided as a physique detection unit, and the physique of the occupant is detected based on a photographed image obtained by photographing the occupant in the vehicle interior. The advantage that it is possible to do this can also be obtained.

(2) Second and Third Embodiments and Other Embodiments FIG. 7 shows a second embodiment of the present invention, and FIG. 8 shows a third embodiment of the present invention. The second and third embodiments are different from the first embodiment in a method of changing the contents (patterns) that can be input according to the physique of the occupant detected by the physique detection means. Accordingly, for the same parts as in the first embodiment, such as the overall configuration of the vehicle air conditioner 1, new illustrations and detailed descriptions are omitted, and only differences from the first embodiment will be described below. State.

  That is, the second embodiment shown in FIG. 7 is configured to change at least one of the upper limit, the lower limit, the left limit, and the right limit of the wind direction settable range A according to the detected physique of the occupant. Has been. In this case, as shown in FIG. 7 (a), in the case of a large occupant (driver), the wind direction settable range A is divided into five sections vertically and equally divided into three columns on the left and right. On the other hand, as shown in FIG. 7B, in the case of a small occupant, the wind direction can be set by excluding the upper limit, the lower limit, the left limit, and the right limit within the wind direction settable range A by a predetermined width. The entire range is a small range A ′. The small range A ′ is divided into five sections vertically and equally divided into three columns on the left and right.

  According to this, by changing the size of the entire range according to the physique of the occupant, the compartment can be made smaller in the case of a small occupant, and the target site is the same as in the first embodiment. And the problem of performing unnecessary fine division can be solved. As a result, even according to the second embodiment, the wind direction of the conditioned air can be set, and an excellent effect that the wind direction can be set satisfactorily regardless of the difference in the occupant's physique is obtained. Can do.

The On the other hand, as shown in FIG. 8B, in the case of a small occupant, for example, 35 sections are provided in which the wind direction settable range A is equally divided into 7 rows vertically and 5 rows horizontally.

  Even in this case, by changing the number of sections into which the wind direction settable range A is divided according to the occupant's physique, in the case of a small passenger, the number of divisions can be increased and one section can be made smaller. The target part can be made equal to the case of a large passenger. Therefore, according to the third embodiment, the wind direction of the conditioned air can be set, and the excellent effect that the wind direction can be set satisfactorily regardless of the difference in the occupant's physique can be obtained. it can.

  Further, although not shown, the changing means is selected according to the occupant's physique detected by the physique detecting means, the size of each section, the upper limit of the wind direction settable range A, the lower limit, the left limit, the right limit, the wind direction Of the number of divisions into which the settable range A is divided into sections, a plurality of combinations can be combined and changed. By combining a plurality of changes in this way, it becomes possible to set the sections more finely, which can be more effective.

In either configuration, the occupant's physique can be detected with sufficient certainty. You may make it detect a physique combining the some structure.

  In addition, for example, the configuration of the remote device (remote operation device) can be variously changed such as one having a rotary dial, and the position where the remote operation device is provided is also around the steering wheel, around the door, etc. Also good. The remote control device may be detachably provided at a position desired by the driver, or may be operated by a driver or an occupant by hand. It is also possible to adopt a configuration in which the function of the remote control device is given to a communication terminal such as a smartphone possessed by the driver or the like.

  In each of the above embodiments, two types of large and small are described as the occupant's physique. However, the occupants are classified into more detailed (three or more levels), and in addition to the height, they are fat. It is also possible to make a distinction such as being. Furthermore, the present invention is appropriately changed within the scope not departing from the gist of the invention, such as the hardware configuration of the entire air conditioning unit, the hardware configuration of the swing register, and the display form on the center display.
