Is loaded into the main storage device and executed.

  Next, processing for displaying image data performed by the display unit 110 will be described in detail with reference to FIG.

  FIG. 4 is a diagram showing an example of a display screen displayed by the control device 100 of the present embodiment. FIG. 4A shows a display screen when the vehicle is stopped, and FIG. A display screen when traveling is shown. As in FIG. 2 described above, the operation button 10 on which “English characters” are written indicates a button for accepting various requests to the audio apparatus 200, and the operation button 20 on which “Katakana characters” are written. Indicates buttons for accepting various requests to the navigation device 300. For convenience of explanation, the same screen as FIG. 2 described above is used in FIG.

  The display unit 110 holds data (display determination data) in which the operation buttons 10 and 20 to be displayed are displayed for each traveling state of the vehicle. Note that there are two running states in the display determination data: “stopped” and “running”.

  Display unit 110 accepts input of image data output from navigation device 300 (for example, “data indicating the current position on a map”). Further, the display unit 110 acquires a signal (data indicating the speed) output from the speed sensor 500 and determines whether the vehicle is in a “stopping” state or a “running” state. When the display unit 110 determines that the vehicle is stopped, the display unit 110 specifies an operation button to be displayed when the vehicle is stopped, using the display determination data held.

  The display unit 110 generates image data for displaying the specified operation button on the image data from the navigation device 300, and displays a display screen (for example, FIG. 4A) for displaying the generated image data. To display.

  The screen 1000 shown in FIG. 4A displays operation buttons 10a to 10e for receiving requests for the five types of audio devices 200 and operation buttons 20a to 20e for receiving requests for the five types of navigation devices 300. is doing.

  And when a vehicle starts driving | running | working, the display part 110 changes the display screen 1000 to the screen 1001 shown in FIG.4 (b). Specifically, when it is determined that the vehicle is traveling from the signal output from the speed sensor 500, the display unit 110 displays when the vehicle is traveling using the display determination data that is held. Identify operation buttons. The display unit 110 generates image data for displaying the specified operation button on the image data from the navigation device 300, and displays a display screen (for example, FIG. 4B) that displays the generated image data. To display.

  A screen 1001 shown in FIG. 4B displays operation buttons 10a to 10h for receiving requests to the eight types of audio devices 200 and operation buttons 20a to 20b for receiving requests to the two types of navigation devices 300. is doing. That is, when detecting the traveling of the vehicle, the display unit 110 reduces the display number of the operation buttons 10 for accepting a request to the navigation device 300 as compared with the display number of the operation buttons 10 displayed during the stop. Yes.

  As described above, when the vehicle is traveling, the number of operation buttons 10 for receiving a request to the navigation device 300 is reduced because the navigation device 300 is operated by a user while traveling. This is because it is considered that there are many functions that are preferable for safety of traveling when the request is not accepted.

  When the display device 110 determines that the vehicle is traveling, the display number of the operation buttons 20 for accepting a request to the audio device 200 is compared with the display number of the operation buttons 20 displayed during the stop. Increasing. The reason for adopting such a configuration is as follows.

  That is, in the in-vehicle device, there is a limit to the enlargement of the screen due to the installation space. When the operation buttons 10 and 20 are to be displayed on the screen, the number of operation buttons 10 and 20 that can be displayed is limited. Therefore, in this embodiment, when the vehicle is traveling, a request for the space on the screen generated by reducing the display number of the operation buttons 10 that accepts various processing requests to the navigation device 300 to the audio device 200 is made. It is assigned to the operation button 20 for receiving, and the space on the screen is used effectively.

  As described above, in the present embodiment, the configuration of the operation buttons 10 and 20 displayed for receiving from the user is automatically changed in accordance with the traveling state of whether the vehicle is traveling or stopped. . Therefore, the operability of the in-vehicle device when the vehicle is traveling can be improved.

  The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the gist of the present invention. For example, in the above-described embodiment, a request from a user is received using the touch panel 420, but the present invention is not particularly limited to this. Any operation button 10 (or 20) displayed on the display screen may be specified. For example, an input device such as a joystick is connected to the control device 100, and a cursor for designating the position of the screen is displayed on the display screen. Then, the user moves the cursor on the screen using the input device, and specifies a desired operation button. Then, the control device 100 performs an operation corresponding to the operation button designated on the screen by the cursor.

  Moreover, although the case where the control apparatus 100 receives the operation request with respect to the audio apparatus 200 and the navigation apparatus 300 was taken as an example in the said embodiment, this is only an illustration. For example, in addition to the audio device 200 and the navigation device 300, or instead of the audio device 200, an operation request of another device such as an air conditioner may be received using an operation button displayed on the display screen. .

  In this embodiment, the case where the control device 100, the audio device 200, and the navigation device are configured as separate devices has been described as an example. However, the control device 100, the audio device 200, and the navigation device are configured as one device. It does not matter.

  In the present embodiment, the operation buttons 10 and 20 are displayed on the left and right ends of the display screen. However, this is only an example. For example, the operation buttons 10 and 20 may be displayed on both upper and lower ends of the display screen.
