  As shown in the layout diagram of FIG. 4, the multistage switch 40 configured as described above is disposed, for example, in the center console between the driver's seat and the passenger seat of the vehicle. The multi-stage switch 40 and the display device 41 constitute a vehicle display system 42 that is electrically connected to the vehicle display device 41.

  The vehicle display system 42 is electrically connected to a vehicle control system such as an air conditioning system 43, an audio system 44, a car navigation system 45, and a telephone / mail system 46, and an operator operates the multistage switch 40. Each vehicle control system is caused to perform a desired operation.

  Next, changes in display on the display device 41 when the multistage switch 40 is operated will be described mainly with reference to FIGS.

  The screen diagram shown in FIG. 5 is an initial display in which the display of the display device 41 becomes a menu screen. This menu screen display is the first layer display.

  In the figure, a map display 51 is displayed on the display device 41, and icon displays 52 </ b> A to 52 </ b> D are displayed on four sides of the map display 51.

  By selecting these icon displays 52A to 52D, the display on the display device 41 shifts to a display screen (second level display) for operating each vehicle control system corresponding to the icon displays 52A to 52D. .

  Here, for example, a case where the icon display 52C is selected will be described. To select the icon display 52C, the operator presses a point D on the upper surface of the movable panel 33 shown in FIG.

  Here, FIG. 6 is a cross-sectional view when the point D of the movable panel 33 is pressed. In the figure, among the push switches 22, the second push switch 22D closest to the lower side of the point D is pushed in and turned ON. On the other hand, the second push switch 22C that is farthest from below the point D is not turned ON. Then, the central first push switch 22A is pushed in a little and is turned on to generate a sense of moderation. Thereby, the screen shifts to the display screen of FIG.

  Of the push switches 22, a feeling of moderation is generated when only the first push switch 22A is turned ON, and the second push switches 22B to 22E are push switches that do not generate a feeling of moderation even when turned ON. The second push switch 22D is ON but does not generate a sense of moderation, and the first push switch 22A is ON and generates a sense of moderation. Since it is possible to recognize that the operation has been confirmed, the operational feeling is improved.

  In the above description, the point D of the movable panel 33 is pressed and the corresponding icon 52C is selected. However, when the points B, C, and E of the movable panel 33 in FIG. 2 are pressed. Shifts to the display of the second hierarchy corresponding to each icon.

  That is, by pressing the upper surface of the movable panel 33, the display shifts to the second level display for operating the vehicle control system.

  As described above, when the operator presses the points B to E, the push switch 22 is switched between ON and OFF. Here, the states of the first push switch 22A and the second push switches 22B to 22E when the respective pressing positions are pressed are shown in (Table 1).

  In Table 1, “ON” indicates that the push switch 22 is ON, “OFF” indicates that the push switch 22 is OFF, and “ON / OFF” indicates that the push switch 22 is ON or OFF. Is shown.

  That is, the second push switch near the pressing position and the first push switch 22A located in the center are turned ON, and the second push switch farthest from the pressing position remains OFF. In accordance with this rule, the control circuit 23 determines which position of the movable panel 33 is pressed.

  Further, when the operator operates the upper surface of the touch panel 32 on the display screen of FIG. 7, the music flowing from the speaker in the vehicle can be changed.

  Here, a display for operating the audio system 44 is shown in the figure, and the tag display unit 61 displays a plurality of pieces of music stored in the hard disk of the audio system 44 by a “Playlist” tag 61A. This is a tag display for switching the display to the order of the albums in which the music is collected or to the singing procedure indicated by the tag 61B of “Artist”.

  In the figure, the “Playlist” tag 61A is selected, and “Playlist1” to “Playlist7” are displayed in the list display section 62. In the figure, “Playlist4” is shown as a selection display 63 and is currently selected. The music of “Playlist4” is flowing from the speaker.

  It should be noted that the selection display 63 is currently selected in the list display section 62, for example, because other displayed “Playlist1” to “Playlist3” and “Playlist5” to “Playlist7” are changed. It has come to understand that.

  Further, “Back” is displayed as the hierarchy change icon display 64, and by selecting this hierarchy change icon display 64, the display shifts from the second hierarchy display to the menu display that becomes the first hierarchy display.

  Then, “Track” is displayed as the hierarchy change icon display 65, and by selecting this hierarchy change icon display 65, the display shifts to the display of the third hierarchy indicating the music constituting the target of the selection display 63.

  Here, when the operator traces the upper surface of the touch panel 32 in the front-rear direction, the selection display 63 changes from “Playlist4” to “Playlist5” or “Playlist3”, and the music flowing from the speaker in the vehicle is “Playlist5” or “Playlist3”. To the music corresponding to the first song.

  Further, for example, when the point E of the movable panel 33 is pressed while “Playlist4” is selected, the hierarchy change icon display 65 is selected, and the display shifts to the display of the third hierarchy shown in FIG.

  In the drawing, “Track 1” to “Track 7” shown in the list display section 71 are displays of a plurality of music pieces constituting an album corresponding to “Playlist 4”. Here, “Track 1” is selected as the selection display 72, and the music “Track 1” is flowing from the speaker. Further, a hierarchy change icon display 73 is displayed as “Back” in the upper right, and an initial return icon display 74 is displayed as “Menu” in the lower left.

  Here, when the operator wants to change the music flowing from the speaker, the user operates by tracing the upper surface of the touch panel 32 in the forward direction as described above. By this operation, the selection display 72 is sequentially changed from “Track 1” to “Track 2” and subsequently “Track 3”, and the music flowing from the speaker is changed.

  Further, when the operator presses the point D of the movable panel 33, the hierarchy change icon display 73 can be selected. By this operation, the display of the display device 41 can be changed from the display of the third hierarchy shown in FIG. 8 to the display of the second hierarchy shown in FIG.

  Further, when the operator presses the point C of the movable panel 33, the initial return icon display 74 can be selected. By this operation, the display of the display device 41 can be changed from the display of the third hierarchy shown in FIG. 8 to the menu display of the first hierarchy shown in FIG.

  That is, by pressing the movable panel 33, the hierarchy displayed on the display device 41 can be changed from the first hierarchy to the second hierarchy, or from the third hierarchy to the first hierarchy and the second hierarchy.

  Thereby, for example, when the operator switches from the operation screen of the audio system 44 to the operation screen of the telephone / mail system 46, the display of the audio system 44 can be displayed in two or more levels such as the third hierarchy with respect to the first hierarchy. Even if it is displayed as an operation screen, it can return to the menu display by selecting the initial return icon display 74. Then, by selecting the icon 52D in the menu display, an operation related to the telephone / mail system 46 can be immediately performed. That is, even if the display of each hierarchy is complicated, it is possible to smoothly operate different vehicle control systems.

  Further, since the display of each layer is switched by the operation on the movable panel 33 instead of the operation on the touch panel 32, the operator can recognize the operation of the movable panel 33 in association with the display of each layer. Thereby, the erroneous operation at the time of switching the display of each hierarchy is suppressed.

  As described above, according to the present embodiment, the plurality of push switches 22, the movable base 31 disposed above the push switches 22, the touch panel 32 disposed on the upper surface of the movable base 31, and the periphery of the touch panel 32 The movable panel 31, the touch panel 32, and the movable panel 33 are tilted as a unit, and a plurality of push switches 22 are pressed when the upper surface of the movable panel 33 is pressed. Since not only the operation of the touch panel 32 but also the operation by pressing the upper surface of the movable panel 33 is possible, the multistage switch 40 capable of performing various operations can be realized.

  Further, the second push switches 22B to 22E are configured to be arranged on a concentric circle centering on the first push switch 22A, and the same is true regardless of which point on the upper surface of the movable panel 33 is pressed. Since it can be determined by the tilt angle, the multistage switch 40 with a good operational feeling can be realized.

  Furthermore, since the first push switch 22A is provided with a sense of moderation and the second push switches 22B to 22E are not provided with a sense of moderation, the operator can recognize that the operation has been confirmed with a single sense of moderation. Thus, the multistage switch 40 having a better operational feeling can be realized.

  Since the vehicle display system 42 includes the display device 41 electrically connected to the multistage switch 40 and the display of the display device 41 is switched when the movable panel 33 of the multistage switch 40 is operated, the touch panel is configured. Since not only 32 but also the operation of the movable panel 33 is used, various operations reflecting the operator's intention more smoothly are possible.

  Further, the display device 41 displays a lower hierarchy that is switched by the operation of the movable panel 33 from the first hierarchy display for selecting the vehicle control system, and is movable in a state in which the lower hierarchy display is displayed. When the panel 33 is operated, the display of the display device 41 is switched to the display of the first hierarchy, so even if it is desired to operate the other vehicle control system via the display device 41, Smooth operation is possible.

  The multistage switch and the vehicle display system using the same according to the present invention have an advantageous effect that various operations can be performed, and are useful mainly for the operation of the vehicle control system.
