Abstract

A dial switch is operative to be rotated or tilted and to be pushed down, which can select any one of icons displayed on a menu screen of a display portion and display information regarding a function of an onboard apparatuses corresponding to a selected icon on the display portion. A central pushing switch is configured to function as a home key such that a default-state menu screen is displayed on the display portion whenever this switch is pushed down. Left or right pushing switches is configured to function as a shortcut key such that information regarding a function of an onboard apparatus corresponding to left-positioned or right-positioned icons positioned on left and right sides of a central icon is displayed on the display portion whenever the left or right pushing switches is pushed down.

Claims

1. An information display device for a vehicle, comprising:

an operational portion provided on a center console in a vehicle compartment;

a display portion provided at a specified position in the vehicle compartment which is visible to a driver; and

a control portion to control display of the display portion in accordance with an operation of the operational portion,

wherein said operational portion comprises a dial switch and at least three pushing switches provided around the dial switch, the dial switch being operative to be rotated or tilted and to be pushed down, the three pushing switches being configured to be pushed down respectively, the three pushing switches being comprised of a central pushing switch and left and right pushing switches which are provided on left and right sides of the central pushing switch, respectively,

said display portion is configured to display at least three different icons which are positioned side by side substantially laterally, together with a selection indication to show which icon is selected, as a menu screen for selecting functions of various onboard apparatuses corresponding to said three icons, the display portion being configured to display a default-state menu screen in which a centrally-positioned icon of said three icons is indicated as a selected icon when said dial switch is in a non-operational state of rotation or tilt,

said control portion is configured to control the display of the display portion such that a position of said selection indication showing the selected icon is changed among said three icons in accordance with an operation of rotation or tilt of the dial switch when the menu screen is displayed on the display portion, and also such that information regarding the function of the onboard apparatus corresponding to the selected icon with the selection indication is displayed in accordance with an operation of down-pushing of the dial switch,

said central pushing switch is configured to function as a home key such that said default-state menu screen is displayed on the display portion whenever the central pushing switch is pushed down, and said left and right pushing switches are configured to function as a shortcut key, respectively, such that information regarding the function of the onboard apparatus corresponding to a left-positioned icon of said three icons is displayed on the display portion whenever the left pushing switch is pushed down, and information regarding the function of the onboard apparatus corresponding to a right-positioned icon of said three icons is displayed on the display portion whenever the right pushing switch is pushed down.

2. The information display device for a vehicle of claim 1, wherein said dial switch is a columnar-shaped switch having a central axis extending vertically, and said three pushing switches are arranged in an arc shape around the dial switch in an area positioned in front of the dial switch.

3. The information display device for a vehicle of claim 2, wherein said changing of the position of the selection indication among the three icons in accordance with the operation of rotation or tilt of the dial switch is executed while respective positions of said three icons displayed on the display portion are kept fixed.

4. The information display device for a vehicle of claim 3, wherein said three icons are displayed in another area than both-end portions of the display portion, and other icons than the three icons are displayed at the both-end portions of the display portion.

5. The information display device for a vehicle of claim 4, wherein a single icon is displayed at each of said both-end portions of the display portion, so that five icons, in total, are displayed on the display portion.

6. The information display device for a vehicle of claim 2, wherein said operational portion further comprises, in addition to said three pushing switches, a pushing switch for returning the display of said display portion to a previous screen and a pushing switch for displaying a screen corresponding to another function which is registered in advance by a driver on the display portion, and said two additional pushing switches are arranged at rearward positions from the three pushing switches.

7. The information display device for a vehicle of claim 3, wherein said operational portion further comprises, in addition to said three pushing switches, a pushing switch for returning the display of said display portion to a previous screen and a pushing switch for displaying a screen corresponding to another function which is registered in advance by a driver on the display portion, and said two additional pushing switches are arranged at rearward positions from the three pushing switches.

8. The information display device for a vehicle of claim 4, wherein said operational portion further comprises, in addition to said three pushing switches, a pushing switch for returning the display of said display portion to a previous screen and a pushing switch for displaying a screen corresponding to another function which is registered in advance by a driver on the display portion, and said two additional pushing switches are arranged at rearward positions from the three pushing switches.

9. The information display device for a vehicle of claim 5, wherein said operational portion further comprises, in addition to said three pushing switches, a pushing switch for returning the display of said display portion to a previous screen and a pushing switch for displaying a screen corresponding to another function which is registered in advance by a driver on the display portion, and said two additional pushing switches are arranged at rearward positions from the three pushing switches.
