Control device, vehicle, computer-readable storage medium, and control method

1. A control device for controlling a display device capable of displaying visual information for a passenger onto a windshield of a moving body, in two or more display regions, wherein

when adjacent target regions of the two or more display regions are in a display state in which the visual information is being displayed, the control device causes the adjacent target regions to be in a non-display state in which the visual information for the passenger is not displayed in a predetermined order, when a predetermined condition is satisfied, and

the control device is configured to determine the target regions and the order, based on a traveling direction of the moving body at the time when the condition is satisfied or a predicted traveling direction of the moving body after the time when the condition is satisfied;

wherein

the order corresponds to, a direction opposite to, the traveling direction of the moving body at the time when the condition is satisfied or the predicted traveling direction of the moving body after the time when the condition is satisfied.

2. The control device according to claim 1 , comprising a recording unit for recording character images associated with each of a plurality of combinations of the target regions and the order, wherein

the control device is configured to acquire, from the recording unit, the character image associated with a combination of the determined target regions and order, and cause the display device to display the character image.

3. The control device according to claim 2 , wherein

the recording unit is configured to record display positions of the character images associated with each of the plurality of combinations, and

the control device is configured to acquire, from the recording unit, a display position of the character image associated with the combination of the determined target regions and order, and display the character image at a display position, which is associated with the combination of the determined target region and order, of the display device.

4. The control device according to claim 3 , wherein

the display position of the character image associated with the combination of the determined target regions and order is located outside of the adjacent target regions.

5. The control device according to claim 2 , wherein

the recording unit is configured to record motion images of characters associated with each of the plurality of combinations, and

the control device is configured to acquire, from the recording unit, a motion image of the character associated with a combination of the determined target regions and order, and cause the display device to display the motion image of the character.

6. The control device according to claim 1 , comprising a recording unit for recording character images associated with each of a plurality of the conditions, wherein

the control device is configured to acquire, from the recording unit, the character image associated with the satisfied condition, and cause the display device to display the character image.

7. The control device according to claim 1 , wherein

the control device is configured to determine a change rate from the display state to the non-display state, based on a speed of the moving body.

8. The control device according to claim 1 , wherein

the control device is configured to increase a change rate from the display state to the non-display state as a speed of the moving body is faster.

9. The control device according to claim 1 , wherein

when the moving body is traveling straight at a higher speed than a predetermined speed, the control device is configured to determine the order in order from an upper display region to a lower display region with respect to a surface on which the moving body moves.

10. The control device according to claim 1 , wherein

the condition includes change of the moving body from a stop state to a moving state.

11. The control device according to claim 1 , wherein

the moving body can drive automatically, and the condition includes lowering in automatic driving level.

12. The control device according to claim 1 , wherein

the control device is configured to superimpose and display the information on a scene that is visually recognized by the passenger.

13. The control device according to claim 12 , wherein

the display device is a head up display.

14. A vehicle comprising the control device according to claim 1 .

15. A non-transitory computer-readable storage medium having a program stored thereon for causing a computer to control a display device capable of displaying visual information for a passenger onto a windshield of a moving body, in two or more display regions, the program being for

causing, when adjacent target regions of the two or more display regions are in a display state in which the visual information is being displayed, the adjacent target regions to be in a non-display state in which the visual information for the passenger is not displayed according to a predetermined order, when a predetermined condition is satisfied, and

determining the target regions and the order, based on a traveling direction of the moving body at the time when the condition is satisfied or a predicted traveling direction of the moving body after the time when the condition is satisfied;

wherein

the order corresponds to, a direction opposite to, the traveling direction of the moving body at the time when the condition is satisfied or the predicted traveling direction of the moving body after the time when the condition is satisfied.

16. A method of controlling a display device capable of displaying visual information for a passenger onto a windshield of a moving body, in two or more display regions, the method comprising:

causing, when adjacent target regions of the two or more display regions are in a display state in which the visual information is being displayed, the adjacent target regions to be in a non-display state in which the visual information for the passenger is not displayed according to a predetermined order, when a predetermined condition is satisfied; and

determining the target regions and the order, based on a traveling direction of the moving body at the time when the condition is satisfied or a predicted traveling direction of the moving body after the time when the condition is satisfied;

wherein

the order corresponds to, a direction opposite to, the traveling direction of the moving body at the time when the condition is satisfied or the predicted traveling direction of the moving body after the time when the condition is satisfied.

17. A control device for controlling a display device capable of displaying visual information for a passenger of a moving body, in two or more display regions, wherein

the control device is configured to cause adjacent target regions of the display regions to change from a display state in which the information is displayed to a display restricted state in which display is restricted, in a predetermined order, when a predetermined condition is satisfied,

the control device is configured to determine the target regions and the order, based on a traveling direction of the moving body at the time when the condition is satisfied or a predicted traveling direction of the moving body after the time when the condition is satisfied, and

when the moving body is traveling straight at a higher speed than a predetermined speed, the control device is configured to determine the order in order from an upper display region to a lower display region with respect to a surface on which the moving body moves.
