Abstract

An in-vehicle display system includes a steering switch disposed at a steering wheel, an in-vehicle display having a display screen, and a touch panel covering the display screen. When an operator operates the touch panel, the in-vehicle display is operable to display a touch panel menu including icons on the display screen. When the operator operates the steering switch while the touch panel menu is displayed on the display screen, the in-vehicle display is operable to replace the touch panel menu with a steering switch menu to display the steering switch menu on display screen. The steering switch menu includes the icons arranged differently than the touch panel menu. This in-vehicle display system is suitably used to operate both of the touch panel and the steering switch.

Claims

1. An in-vehicle display system configured to be mounted to a vehicle including a steering wheel, the in-vehicle display system comprising:

a steering switch disposed at the steering wheel;

an in-vehicle display having a display screen; and

a touch panel covering the display screen,

wherein the in-vehicle display is operable to;

when an operator operates the touch panel, display a touch panel menu including a plurality of icons on the display screen; and

when the operator operates the steering switch while the touch panel menu is displayed on the display screen, replace the touch panel menu with a steering switch menu to display the steering switch menu on display screen, the steering switch menu including the plurality of icons arranged differently than the touch panel menu.

2. The in-vehicle display system according to claim 1,

wherein the plurality of icons are arranged in a matrix form in the touch panel menu, and

wherein the plurality of icons are arranged along an ellipse circumference in the steering switch menu.

3. The in-vehicle display system according to claim 1, wherein, when the operator touches the touch panel at a position of a certain icon out of the plurality of icons while the steering switch menu is displayed on the display screen, the certain icon is selected.

4. The in-vehicle display system according to claim 1,

wherein the touch panel menu has a plurality of first menu layers,

wherein the steering switch menu has a plurality of second menu layers corresponding to the plurality of first menu layers, respectively,

wherein, when the operator operates the steering switch while a certain first menu layer out of the plurality of first menu layers of the touch panel menu is displayed on the display screen, the in-vehicle display is operable to replace the certain first menu layer display with a certain second menu layer out of the plurality of second menu layers of the steering switch menu corresponding to the certain first menu layer to display the certain second menu layer on the display screen.

5. The in-vehicle display system according to claim 4,

wherein the plurality of first menu layers of the touch panel menu are not displayed on the display screen simultaneously to each other;

and

wherein the plurality of second menu layers of the steering switch menu are not displayed on the display screen simultaneously to each other.

6. The in-vehicle display system according to claim 4, wherein the plurality of icons are displayed both in the certain first menu layer of the touch panel menu and the certain second menu layer of the steering switch menu.

7. The in-vehicle display system according to claim 4,

wherein the plurality of icons are displayed in the certain second menu layer of the steering switch menu, and

wherein, when the operator touches the touch panel at a position of one icon out of the plurality of icons while the certain second menu layer of the steering switch menu is displayed on the display screen, the in-vehicle display is operable to replace the certain second menu layer with a first menu layer out of the plurality of first menu layers of the touch panel menu to display the first menu layer on the display screen.

8. An controller for an in-vehicle display system including a touch panel display device and a steering switch coupled to the controller, and a plurality of in-vehicle control devices operatively controlled by the controller, the controller being configured to:

generate a top level touch panel menu to be displayed on the touch panel display device, the top level touch panel menu including a plurality of icons associated with the plurality of in-vehicle control devices;

generate a second level touch panel menu to be displayed on the touch panel display device in response to a selection of one of the plurality of icons via the touch panel display device;

generate a top level steering switch menu to be displayed on the touch panel display device, the top level steering switch menu display including a plurality of icons associated with the plurality of in-vehicle control devices, the plurality of icons arranged differently from those of the top level touch panel menu;

generate a second level steering switch menu to be displayed on the touch panel display device in response to a selection of one of the plurality of icons via the steering switch;

switch from one of the top level touch panel menu and the second level touch panel menu to one of the top level steering switch menu and the second level steering switch menu when the steering switch is operated to make a selection during display of the top level touch panel menu display or the second level touch panel menu; and

switch from one of the top level steering switch menu and the second level steering switch menu to one of the top level touch panel menu and the second level touch panel menu when the touch panel display device is operated to make a selection during the second level touch panel menu display.
