Abstract

The multi display screen is constituted of a wide-screen displaying simultaneously two or more of a navigation search control screen setting necessary requirements to search for a route from a place of departure to a destination of a vehicle, a navigation map screen displaying the position of the vehicle on a map, a night vision screen recognizing an object on a road at night by infrared, a back guide monitor screen for recognizing a rear side of the vehicle, a blind corner monitor screen for recognizing an orthogonal direction of the vehicle, and a hands-free transmission/reception screen of a car phone. Screens to be displayed on the multi-display screen constituted of the wide screen is selected according to a vehicle driving state detected in a vehicle driving state detecting unit, and a display on the multi-display screen of a “screen 1”, a “screen 2”, and a “screen 3” constituted of the wide screen is determined according to the vehicle driving state detected in the vehicle driving state detecting unit.

Claims

1. A multi-screen display device, comprising:

a multi-display screen displaying simultaneously two or more of various screens of a navigation device, various imaging screens of a camera imaging an outside of a vehicle, and various screens of a hands-free transmission/reception device of a car phone; and

a control circuit selecting screens displayed on the multi-display screen according to a vehicle driving state and determining an arrangement of the selected screens on the multi-display screen according to the vehicle driving state.

2. The multi-screen display device according to claim 1, wherein

a determination according to the vehicle driving state is based on one or more state determinations out of a determination of traveling on a road by a navigation function, a determination of stop of traveling of the vehicle, a vehicle speed determination, a determination of a lighting state of a light, a range position determination of a shift lever, a determination of an operation state of a parking brake, and a hands-free transmission/reception determination of a car phone.

3. The multi-screen display device according to claim 1, wherein

the control circuit, in which a determination of traveling on a road is performed by the navigation function, estimates a vehicle stop time by a determination of stop of traveling of the vehicle, a range position determination of a shift lever, a determination of a vehicle speed state and an operation state of a parking brake, and determines a screen needed to be displayed on the multi-display screen and a display position on the multi-display screen.

4. The multi-screen display device according to claim 1, wherein

the control circuit learns an operation by a driver while driving as the vehicle driving state, and thereby determines a display screen with respect to the multi-display screen.

5. The multi-screen display device according to claim 1, wherein

in a determination according to the vehicle driving state, when a navigator rides together in a passenger seat, a navigation search control screen or a navigation map screen is displayed on a display screen on a passenger seat side separated farthest from the driver.

6. The multi-screen display device according to claim 1, wherein

a measurement display screen constituted of one of a display of measuring instruments such as a speedometer and/or an inter-vehicle distance display for recognizing a preceding vehicle by a radar and maintaining an inter-vehicle distance according to the speed is further added to the multi-display screen.

7. The multi-screen display device according to claim 1, wherein

the multi-display screen has two to five screen displays.

8. The multi-screen display device according to claim 1, wherein

in the navigation map screen, a different navigation map screen is used.

9. The multi-screen display device according to claim 8, wherein

the use of the different navigation map screen is of screens having a different scale size and/or a two-dimensional or three-dimensional map screen.

10. The multi-screen display device according to claim 2, wherein

the control circuit, in which a determination of traveling on a road is performed by the navigation function, estimates a vehicle stop time by a determination of stop of traveling of the vehicle, a range position determination of a shift lever, a determination of a vehicle speed state and an operation state of a parking brake, and determines a screen needed to be displayed on the multi-display screen and a display position on the multi-display screen.

11. A program of a multi-screen display device, comprising:

displaying on a multi-display screen simultaneously at least two or more of various screens of a navigation device, various imaging screens of a camera imaging an outside of a vehicle, and various screens of a hands-free transmission/reception device of a car phone; and

switching screens displayed on the multi-display screen according to a vehicle driving state and changing an arrangement of selected screens displayed on the multi-display screen according to the vehicle driving state.
