Abstract

A screen formation system includes: a vehicle condition determination processing unit that determines a vehicle condition; a storage device containing, recorded therein, a candidate screen map in which vehicle conditions and candidate screens are interrelated, each candidate screen representing a screen that is highly likely to be shown on a display unit next after a current screen on the basis of the determined vehicle condition; a candidate screen acquisition processing unit that acquires the candidate screen corresponding to the vehicle condition by referring to the candidate screen map; an off-screen drawing processing unit that draws the acquired candidate screen as an off-screen while the current screen is shown on the display unit; and a screen formation processing unit that shows the off-screen on the display unit responsive to an instruction for a screen change from the current screen made by an operator.

Claims

1. A screen formation system for formation of screens for display on a display unit comprising:

a vehicle condition determination processing unit that determines a vehicle condition;

a storage device;

a candidate screen map, recorded in the storage device, in which vehicle conditions and candidate screens are interrelated, each candidate screen representing a screen that is highly likely to be shown on a display unit next after a current screen on the basis of the determined vehicle condition;

a candidate screen acquisition processing unit that acquires, from the storage device, the candidate screen corresponding to the determined vehicle condition by referring to the candidate screen map;

an off-screen drawing processing unit that draws the acquired candidate screen as an off-screen while the current screen is shown on the display unit; and

a screen formation processing unit that shows the off-screen on the display unit responsive to an instruction for a screen change from the current screen made by an operator.

2. The screen formation system according to claim 1, wherein

the vehicle condition is a vehicle driving state that indicates a vehicle state associated with driving, and the vehicle driving state and a corresponding candidate screen are correlated in the candidate screen map stored in the storage device.

3. The screen formation system according to claim 1, wherein

the vehicle condition is a vehicle environment, and a vehicle environment state that indicates an environment surrounding a vehicle and a corresponding candidate screen are correlated in the candidate screen map stored in the storage device.

4. The screen formation system according to claim 1, further comprising:

a learning processing unit that learns the screen change instruction from the operator; and

a candidate screen map setting processing unit that sets the candidate screen map based on the learning by the learning processing unit.

5. The screen formation system according to claim 1, wherein

the candidate screen map is set according to an operating state of an auxiliary device.

6. The screen formation system according to claim 1, wherein

priorities are assigned to the vehicle conditions in the candidate screen map, and the candidate screen acquisition processing unit acquires the candidate screen based on the priorities.

7. The screen formation system according to claim 1, wherein

a plurality of candidate screens are set corresponding to the vehicle condition and priorities are assigned to the respective candidate screens in the candidate screen map, and the candidate screen acquisition processing unit acquires a candidate screen based on the priorities.

8. A screen formation method comprising:

determining a vehicle condition;

recording, in a storage device, a candidate screen map in which vehicle conditions and candidate screens are interrelated, each candidate screen representing a screen that is highly likely to be shown on a display unit next after a current screen on the basis of the determined vehicle condition;

acquiring the candidate screen corresponding to the determined vehicle condition by referring to the candidate screen map;

drawing the acquired candidate screen as an off-screen while the current screen is shown on the display unit; and

showing the off-screen on the display unit responsive to an instruction for a screen change from the current screen made by an operator.

9. A computer-readable medium having encoded thereon, program causing a computer to function as:

a vehicle condition determination processing unit that determines a vehicle condition;

a storage device containing, recorded therein, a candidate screen map in which vehicle conditions and candidate screens are interrelated, each candidate screen representing a screen that is highly likely to be shown on a display unit next after a current screen on the basis of the determined vehicle condition;

a candidate screen acquisition processing unit that acquires, from the storage device, the candidate screen corresponding to the determined vehicle condition by referring to the candidate screen map;

an off-screen drawing processing unit that draws the acquired candidate screen as an off-screen while the current screen is shown on the display unit; and

a screen formation processing unit that shows the off-screen on the display unit responsive to an instruction for a screen change from the current screen made by an operator.
