Abstract

An information display device includes a preset course information receiver, a symbol display processor, a change mode execution processor, and a preset course information transmitter. The preset course information receiver receives preset course information from an automatic steering device. The symbol display processor displays a symbol representing a preset course on a display screen to correspond to position information of a mobile body based on the preset course information. The change mode execution processor executes a change mode for changing the preset course information based on a fact that the symbol has been designated with a manipulation component. The preset course information transmitter transmits the preset course information changed during the change mode to the automatic steering device. The symbol display processor changes an orientation of the symbol representing the preset course according to a change operation in the preset course information with the manipulation component during the change mode.

Claims

1. An information display device configured to display position information of a mobile body along with map information on a display screen of a display component and configured to transmit a signal to an automatic steering device based on an operation of a manipulation component, the information display device comprising:

a preset course information receiver configured to receive preset course information from the automatic steering device;

a symbol display processor configured to display a symbol representing a preset course on the display screen so as to correspond to the position information of the mobile body based on the preset course information received by the preset course information receiver;

a change mode execution processor configured to execute a change mode for changing the preset course information based on a fact that the symbol displayed on the display screen has been designated with the manipulation component; and

a preset course information transmitter configured to transmit the preset course information changed during the change mode to the automatic steering device,

the symbol display processor being further configured to change an orientation of the symbol representing the preset course according to a change operation in the preset course information with the manipulation component during the change mode.

2. The information display device according to claim 1, further comprising

an operation transition instruction transmitter configured to transmit a transition instruction about an operating mode of the automatic steering device according to whether or not the changed preset course information is a course headed for a preset waypoint.

3. The information display device according to claim 1, further comprising

an obstacle detection processor configured to detect an obstacle present in a specific target region that includes the mobile body, and

a notification processor configured to notify a user when the preset course information changed during the change mode is a course headed for the obstacle detected by the obstacle detection processor.

4. The information display device according to claim 1, wherein

the manipulation component includes a touch panel, and

the change mode execution processor is further configured to execute the change mode based on a fact that the symbol displayed on the display screen has been designated by an operation of the touch panel.

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

the manipulation component includes a rotary manipulation component with which an amount of operation varies according to a rotation operation, and

the symbol display processor is configured to changes the orientation of the symbol representing the preset course in response to the rotation operation of the rotary manipulation component during the change mode.

6. The information display device according to claim 1, wherein

the preset course information transmitter is further configured to transmit the changed preset course information to the automatic steering device when a specific amount of time has elapsed since the manipulation component is used to perform the change operation in the preset course information during the change mode.

7. The information display device according to claim 1, wherein

the preset course information transmitter is further configured to transmit the changed preset course information to the automatic steering device when the manipulation component has sent an instruction to transmit the preset course information to the automatic steering device after the manipulation component has been used to perform the change operation in the preset course information during the change mode.

8. The information display device according to claim 2, wherein,

the operation transition instruction transmitter is further configured to transmit the transition instruction about the operating mode according to whether or not a position where a finger has left the symbol is the waypoint when the preset course information has been changed by a drag operation of the symbol during the change mode.

9. The information display device according to claim 2, further comprising

an obstacle detection processor configured to detect an obstacle present in a specific target region that includes the mobile body, and

a notification processor configured to notify a user when the preset course information changed during the change mode is a course headed for the obstacle detected by the obstacle detection processor.

10. The information display device according to claim 3, further comprising

a detail view display processor configured to display a detail view of the target region on the display screen, and

a target region change processor configured to set a display range of the detail view to the target region when the manipulation component has been manipulated to change the display range of the detail view.

11. The information display device according to claim 4, further comprising

a slide region display processor configured to display on the display screen a slide region in which the preset course information is changed by a slide operation on the touch panel,

the symbol display processor being further configured to change the orientation of the symbol representing the preset course in response to the slide operation in the slide region.

12. The information display device according to claim 4, wherein

the symbol display processor is further configured to change the orientation of the symbol representing the preset course in response to a drag operation of the symbol during the change mode.

13. The information display device according to claim 8, further comprising

an obstacle detection processor configured to detect an obstacle present in a specific target region that includes the mobile body, and

a notification processor configured to notify a user when the preset course information changed during the change mode is a course headed for the obstacle detected by the obstacle detection processor.

14. The information display device according to claim 9, further comprising

a detail view display processor configured to display a detail view of the target region on the display screen, and

a target region change processor configured to set a display range of the detail view to the target region when the manipulation component has been manipulated to change the display range of the detail view.

15. The information display device according to claim 13, further comprising

a detail view display processor configured to display a detail view of the target region on the display screen, and

a target region change processor configured to set a display range of the detail view to the target region when the manipulation component has been manipulated to change the display range of the detail view.

16. A course setting method comprising:

a preset course information reception step of receiving preset course information from an automatic steering device;

a symbol display processing step of displaying a symbol representing a preset course on a display screen of a display component so as to correspond to position information of a mobile body based on the preset course information received in the preset course information reception step;

a change mode execution processing step of executing a change mode for changing the preset course information based on a fact that the symbol displayed on the display screen has been designated by a manipulation component; and

a preset course information transmission step of transmitting the preset course information changed during the change mode to the automatic steering device,

in the symbol display processing step, an orientation of the symbol representing the preset course being changed in response to a change operation in the preset course information with the manipulation component during the change mode.
