Abstract

A first display panel and a second display panel display information used for vehicle driving. An information acquisition unit acquires a condition of the vehicle. A switching unit switches from a first display mode of the first display panel and the second display panel to a second display mode of the first display panel and the second display panel for displaying information of a smaller information volume than an information volume of information displayed in the first display mode, based on the condition of the vehicle acquired in the information acquisition unit.

Claims

1. A vehicle display device comprising:

a display panel that displays information used for vehicle driving;

an information acquisition unit that acquires a condition of the vehicle; and

a switching unit that switches from a first display mode of the display panel to a second display mode of the display panel for displaying information of a smaller information volume than an information volume of information displayed in the first display mode by configuring a visible area to be smaller than that of the first display mode, based on the condition of the vehicle acquired in the information acquisition unit,

wherein the display panel comprises;

a first display panel, and

a second display panel that includes a display surface, the display surface being oriented toward a user when the first display panel is stored in a dashboard of the vehicle, and the display surface not being oriented toward the user when the first display panel is not stored in the dashboard of the vehicle, and

wherein the switching unit uses the first display panel to implement the first display mode and uses the second display panel with a display area smaller than a display area of the first display panel to implement the second display mode.

2. The vehicle display device according to claim 1, wherein

the information acquisition unit acquires information on the traveling vehicle as a condition of the vehicle, and

the switching unit switches from the first display mode of the display panel to the second display mode of the display panel for displaying information of a smaller information volume than an information volume of information displayed in the first display mode by configuring the visible area to be smaller than that of the first display mode, when the information on the traveling vehicle acquired in the information acquisition unit indicates that it is necessary to make a judgment on a condition in the neighborhood of the vehicle.

3. The vehicle display device according to claim 2, wherein

the information acquisition unit acquires a current position of the vehicle and facility information corresponding to the current position, as the information on the traveling vehicle, and

the switching unit switches from the first display mode to the second display mode when the information on the traveling vehicle acquired in the information acquisition unit indicates that the vehicle is traveling in a parking lot or on a shopping street.

4. The vehicle display device according to claim 2, wherein

the information acquisition unit acquires a current position of the vehicle and road information corresponding to the current position, as the information on the traveling vehicle, and

the switching unit switches from the first display mode to the second display mode when the information on the traveling vehicle acquired in the information acquisition unit indicates that the vehicle is traveling on a road of less than a predetermined width.

5. The vehicle display device according to claim 1, wherein

the information acquisition unit acquires information on the traveling vehicle as a condition of the vehicle, and

the switching unit switches from the first display mode of the display panel to the second display mode of the display panel for displaying information of a smaller information volume than an information volume of information displayed in the first display mode by configuring the visible area to be smaller than that of the first display mode, when the information on the traveling vehicle acquired in the information acquisition unit indicates that the vehicle continues to travel in a condition in which a driver should gaze ahead of the vehicle.

6. The vehicle display device according to claim 5, wherein

the information acquisition unit acquires a current position of the vehicle and road information corresponding to the current position, as the information on the traveling vehicle, and

the switching unit switches from the first display mode to the second display mode when the information on the traveling vehicle acquired in the information acquisition unit indicates that the vehicle is traveling on an automobile-only road or a road with a large number of corners.

7. The vehicle display device according to claim 5, wherein

the information acquisition unit acquires information on the traveling vehicle as the information on the traveling vehicle, and

the switching unit switches from the first display mode to the second display mode when the information on the traveling vehicle acquired in the information acquisition unit indicates that the vehicle is traveling on an automobile-only road and is in a cruise control operation.

8. The vehicle display device according to claim 1, wherein

the information acquisition unit is a detection unit that detects whether a dashboard of the vehicle is illuminated by sunlight, and

the switching unit switches from the first display mode of the display panel to the second display mode of the display panel for displaying information of a smaller information volume than an information volume of information displayed in the first display mode by configuring the visible area to be smaller than that of the first display mode, when the detection unit detects illumination by sunlight.

9. The vehicle display device according to claim 8, wherein

the detection unit is located at a position where it is possible to detect illumination by sunlight from behind the vehicle.

10. The vehicle display device according to claim 1, wherein

the information acquisition unit is a detection unit that detects a temperature of the display panel, and

the switching unit switches from the first display mode of the display panel to the second display mode of the display panel for displaying information of a smaller information volume than an information volume of information displayed in the first display mode by configuring the visible area to be smaller than that of the first display mode, when the detection unit detects a temperature of a predetermined level of higher.

11. The vehicle display device according to claim 10, wherein

the detection unit is located at a position where it is possible to detect a temperature in a dashboard of the vehicle in which the display panel is provided.

12. The vehicle display device according to claim 1, wherein

the switching unit exposes the display panel to implement the first display mode and exposes a portion of the display panel such that a display area of the display panel is smaller than in the first display mode, thereby implementing the second display mode.

13. The vehicle display device according to claim 1, wherein at least a traveling speed of the vehicle is displayed in the second display mode.

14. The vehicle display device according to claim 12, wherein at least a traveling speed of the vehicle is displayed in the second display mode.

15. A vehicle display device comprising:

a display panel that displays information used for vehicle driving;

an information acquisition unit that acquires a condition of the vehicle; and

a switching unit that switches from a first display mode of the display panel to a second display mode of the display panel for displaying information of a smaller information volume than an information volume of information displayed in the first display mode by configuring a visible area to be smaller than that of the first display mode, based on the condition of the vehicle acquired in the information acquisition unit,

wherein the switching unit exposes the display panel to implement the first display mode and exposes a portion of the display panel such that a display area of the display panel is smaller than in the first display mode, thereby implementing the second display mode.

16. The vehicle display device according to claim 15, wherein at least a traveling speed of the vehicle is displayed in the second display mode.
