And a means (55). (Invention of Claim 1)

  According to this, when the user performs an operation for setting / changing the wind direction in the remote operation device (59), the control means (3) operates the wind direction adjusting mechanism (42) based on the operation. Thereby, the direction of the conditioned air according to the user's remote operation can be obtained. When a wind direction setting / changing operation is performed on the remote control device (59), the feedback means (55) notifies the user that the wind direction has been changed. At this time, the notification by the feedback means (55) can be performed promptly after the operation, and can be performed without the driver taking the driving viewpoint and looking at the center display.

  Therefore, according to the first aspect of the present invention, the wind direction of the conditioned air can be set by remote control, and the user can quickly confirm whether or not the set wind direction is intended. Effects can be obtained.

Therefore, the air conditioner ECU 3 functions as control means.

  As shown in FIG. 5, 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. An audio ECU 56 is connected to the in-vehicle LAN 54. The audio ECU 56 outputs sound, music, and the like from the speakers 57 provided at least in two places on the left and right sides in the vehicle interior. As will be described later, a notification sound for notifying the user of the setting / change of the wind direction is output from these speakers 57, and functions as a part of feedback means.

  The operation input device 4 includes a control unit 55 configured to include a computer. The display unit 49 to 52 is connected to the control unit 55, and a center display 58 and a remote operation device as a remote operation device are connected. A device 59 is connected. 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. Further, the control unit 55 controls the display of the indicators 49 to 52.

  The remote device 59 is provided for the user 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 the in-vehicle devices 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 in an arbitrary direction and a determination switch including a push button switch. The detection signal and the determination switch operation signal are 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, a user 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, with respect to the direction of the conditioned air blown from the face outlets 21, 22, 31, 32, for example, as shown in FIG. The wind direction is set so that the wind is directed to any one (one or a plurality of continuous) areas divided into a total of nine areas with three steps in the vertical direction and three rows in the horizontal direction, centering on the neck portion of (Change) can be done.

  In setting / changing the wind direction, the control unit 55 overlaps the contour display O representing the upper part from the chest of the occupant on the screen of the center display 58, and is divided into nine regions (vertical and horizontal). And a cursor C is displayed in the currently set wind direction area. The user can move the cursor C in a desired direction (region) by operating the operation knob of the remote device 59. By turning on the decision switch in this state, the wind direction can be set / changed. In this case, the setting operation can be performed without looking at the center display 58.

  Based on the setting operation, control unit 55 outputs a wind direction setting signal to air conditioner ECU 3. 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, The conditioned air is blown out in the set wind direction. Needless to say, the setting and changing of the wind direction can be performed directly by touching the touch panel on the screen of the center display 58.

  Then, as will be described in the following description of the operation, the control unit 55 determines the wind direction when an operation for setting / changing the wind direction blown out from the face outlets 21, 22, 31, 32 is performed in the remote device 59. A process for notifying the user that the change has been made is executed, and a function as a feedback means is realized. In the present embodiment, notification of a change in wind direction is performed by executing all three notification modes described below.

  In the present embodiment, as a first notification mode, notification of a change in wind direction is performed using changes in wind blown from the face outlets 21, 22, 31, and 32. Specifically, the control unit 55 outputs a wind direction setting signal to the air conditioner ECU 3 to change the wind direction, and after the wind direction is changed, that is, after each swing register 42 is operated, the air volume of the blower 6 is maximized. The air volume of the conditioned air is temporarily increased, and after a few seconds have elapsed, the air volume is returned to the original air volume. Accordingly, the air conditioner ECU 3, the blower 6 and the like also function as part of the feedback means.

  Further, the notification of the change in wind direction can also be performed using a sound (notification sound) output from the speaker 57, and a notification mode using this notification sound is referred to as a second notification mode. Specifically, the control unit 55 causes the audio ECU 56 to output notification sounds corresponding to the absolute direction of the wind direction, in this case, nine directions, from the speaker 57. For example, the vertical direction position of the wind direction (upper, middle, lower) is represented by the pitch of the sound (high, medium, low), and the left and right direction of the wind (left column, middle column, right column) It is expressed by the volume of sound in the left / right direction (sound from the left, sound from the center, sound from the right) output to the passenger compartment.

  Furthermore, as notification of the change of the wind direction, it can also be performed using the indicators 49, 50, 51, 52 provided in the vicinity of the face outlets 21, 22, 31, 32. The mode of notification used is referred to as a third notification mode. Specifically, when the wind direction is changed, the control unit 55 changes the lighting state of the indicators 49 to 52 with the contents associated with the changed wind direction. For example, the vertical direction position of the wind direction is expressed by the light color (for example, blue, green, yellow, etc.) of the display devices 49 to 52, and the horizontal direction of the wind direction is the position where each of the display devices 49 to 52 shines ( Left, middle, and right areas).

  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 a procedure of processing executed by the control unit 55 when a wind direction changing operation regarding the face outlets 21, 22, 31 and 32 in the vehicle air conditioner 1 is performed. Here, for example, when the driver wants to change the wind direction of the conditioned air blown from the face air outlets 21, 22, 31, 32 of the vehicle air conditioner 1, the driver inputs the wind direction change by operating the remote device 59 or the touch panel. To do. At this time, even when the driver is driving, the driver can input the change without taking the driving field of view by operating the remote device 59.

  However, when the direction of the conditioned air is set by remote operation of the remote device 59, the face outlets 21, 22, 31, 32 are located in the back of the instrument panel 41, and the driver changes the direction of the louvers 43, 44. There are circumstances that cannot be seen directly. Therefore, there is a possibility that the driver may take a driving viewpoint out of view for viewing the display on the center display 58, or it may take time for confirmation. Therefore, in the present embodiment, the control unit 55 notifies that the wind direction has been changed as shown in FIG. 6 so that the driver does not have to look at the display on the center display 58.

  That is, first, in step S1, it is determined whether or not a wind direction change has been input. If there is an input for changing the wind direction (Yes in step S1), it is determined whether or not the input is from the remote device 59 in the next step S2. When the input of the change of the wind direction is made by touch panel operation instead of the remote device 59 (No in step S2), the process of changing the wind direction by the air conditioner ECU 3 is performed in the next step S3, and the process ends. To do.

  On the other hand, when the change of the wind direction is input by the remote device 59 (Yes in step S2), the user is notified by the output of the notification sound from the speaker 57 (second notification mode) in step S4. The wind direction is notified to. As described above, the notification sound is output from the speaker 57 as a notification sound having a pitch output position corresponding to one of the nine absolute directions of the changed wind direction. Is done. At this time, since the sound is used, the user can be promptly notified without taking the driving line of sight off.

  At the same time, in step S5, the wind direction is notified to the user by the display (third notification mode) of the display devices 49, 50, 51, and 52. As described above, the notification by the display devices 49 to 52 is performed by changing the lighting state of the display devices 49 to 52. For example, the light of the display devices 49 to 52 associated with the changed wind direction is displayed. The display is performed in the color and the position where it shines. At this time, since the indicators 49 and 50 are provided in the vicinity of the face outlets 21 and 22 in front of the driver, prompt notification can be made with less line-of-sight movement than when the center display 58 is viewed. It becomes.

  Next, in step S6, a process for changing the wind direction by the air conditioner ECU 3 is performed. In the next steps S7 to S9, notification of the wind direction to the user is performed by the change in the wind blown from the face outlets 21, 22, 31, 32 (first notification mode). In step S7, the air volume of the conditioned air is temporarily increased by maximizing the air volume of the blower 6. In step S8, it is determined whether several seconds have elapsed. When several seconds have elapsed (Yes in step S8), the air volume of the blower 6 is returned to the original set value in step S9, and the process ends.

  Thereby, the notification to the user is performed by blowing the wind instantaneously with a large air volume like an air gun in the changed wind direction. By receiving the wind like an air cannon on the body, the user can easily feel the set wind direction in a short time, and an easy-to-understand notification is given without the user taking his driving gaze off. In this case, since the configuration originally provided in the vehicle air conditioner 1 is used, there is no need to add a separate configuration for notification.

  Thus, according to the vehicle air conditioner 1 of the present embodiment, when the wind direction is set / changed on the remote device 59, the user is notified that the wind direction has been changed. This notification can be performed promptly after the operation of the remote device 59, and can be performed without the driver removing the driving viewpoint and looking at the center display 58. As a result, according to the present embodiment, the air direction of the conditioned air can be set by remote control, and the user can quickly confirm whether or not the set wind direction is intended. An effect can be obtained.

  In particular, in the present embodiment, notification by a change in wind blown from the face outlets 21, 22, 31, 32 (first notification mode), notification by a notification sound output from the speaker 57 (second notification mode) , A configuration for performing notification in all three notification modes of notification (third notification mode) according to the lighting state of the indicators 49, 50, 51, 52 provided near the face outlets 21, 22, 31, 32, and did. As a result, it is possible for the user to make a quicker and easier-to-understand notification.

  In addition, although illustration is abbreviate | omitted, this invention is not limited to one Embodiment shown above and shown in drawing, Various expansion | extension and a change like the other embodiment described below are possible. In other words, the configuration of the remote device (remote operation device) can be changed in various ways, such as those having a rotary dial, and the position where the remote operation device is provided can be around the steering wheel or the door. good. The remote control device may be detachably provided at a user's desired position, or may be operated by the user holding it 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 user.

  Also, when notification is made using changes in the wind blown out from the face outlets 21, 22, 31, 32, the airflow is adjusted by temporarily lowering or stopping the air-conditioning air volume and then returning it to the original air volume. It can be configured to notify the user of the change. Accordingly, since the user feels a new wind from a state in which the user hardly feels the wind or a state in which the wind is not felt, it becomes possible to notify the new wind direction in an easy-to-understand manner while eliminating confusion about the wind direction. .

  Or you may comprise so that a user may be notified of the change of a wind direction by diffusing an air-conditioning wind temporarily, and setting it as the wind direction set after that. Thereby, after the user feels the diffusion of the wind, it is possible to notify the new wind direction in an easy-to-understand manner by making the wind feel. It is also possible to implement these configurations in combination with the configuration in which the air gun of the above-described embodiment notifies.

  When notification is performed by outputting a notification sound, by outputting a notification sound corresponding to the direction in which the wind direction is changed, that is, the relative change direction of the wind direction, such as higher, lower, more left, more right The user may be notified of a change in wind direction. Thereby, the user can know the relative change of the wind direction. The notification sound can be configured to be output with the content associated with the wind direction with respect to at least one of the pitch, the number of sounds, the volume, and the chord. In either case, the user can be notified in an easy-to-understand manner. It is also possible to notify the wind direction by outputting (reading) synthesized speech.

  When notification is performed using the lighting state of the display devices 49 to 52, at least one of light color, luminance, range, continuous or blinking, and movement of the lighting position is changed according to the contents associated with the wind direction. It can be constituted as follows. By these, the wind direction itself or its change can be expressed, and a display that is easy for the user to understand is possible. Of course, various changes can be made to the structure of the display.

  In the one embodiment, a first notification mode using changes in wind blown from the face outlets 21, 22, 31, 32, a first notification mode for performing notification by outputting a notification sound from the speaker 57, Although it was set as the structure which notifies using all the 3rd notification aspects which notify using the lighting state of the display devices 49-52, it performs one of the 1st-3rd notification aspects, or 2 You may comprise so that it may notify by one combination. By performing notification in at least one of the modes, it is possible to achieve the intended purpose that the user can quickly confirm whether the set wind direction is the intended one.

  Furthermore, in the above embodiment, the function as the feedback means is realized mainly by the processing of the control unit 55 of the operation input device 4, but the processing may be mainly performed by the air conditioner ECU 3. In addition, for example, various changes can be made to the overall hardware configuration of the air conditioning unit, the hardware configuration of the swing register, the display form on the center display, etc. It can be implemented with appropriate changes.
