Abstract

In a display control device for a vehicle to control a display on a head-up display, when lane change information related to a lane change of the vehicle is acquired from a lane change control unit that controls the lane change of the vehicle, a lane change content indicating an estimated trajectory of the lane change is displayed to be superimposed on a road surface as a superimposition target based on the lane change information.

First claim

What is claimed is:

1. A display control device for a vehicle to control a display on a head-up display, the display control device comprising:
a control information acquisition unit that acquires driving control information related to a driving control of the vehicle, from a lane keeping control unit that controls an in-lane traveling of the vehicle to cause the vehicle to travel in a lane;
a change information acquisition unit that acquires lane change information related to a lane change of the vehicle, from a lane change control unit that controls the lane change of the vehicle; and
a display control unit that displays an estimated trajectory content indicating an estimated trajectory of the in-lane traveling to be superimposed on a road surface as a superimposition target, based on the driving control information, wherein
in response to acquiring the lane change information during the in-lane traveling, the display control unit displays a lane change content indicating an estimated trajectory of the lane change together with the estimated trajectory content, based on the lane change information, and
in response to recognizing interruption of the lane change based on the lane change information, the display control unit highlights the estimated trajectory content on the display by extending the estimated trajectory in a traveling direction in the lane beyond a transition point at which the lane change was to be performed.

2. The display control device according to claim 1 , wherein
the display control unit displays the lane change content indicating the estimated trajectory of the lane change to be superimposed on the road surface and to be integrally continuous with the estimated trajectory content.

3. The display control device according to claim 1 , wherein
the display control unit displays the lane change content at a position that does not overlap with the estimated trajectory content.

4. The display control device according to claim 1 , wherein
the display control unit displays the lane change content at a position visually recognized on a far side with respect to the estimated trajectory content.

5. The display control device according to claim 1 , wherein
the lane change information includes destination lane information related to a destination lane to which the vehicle moves by the lane change, and
the display control unit displays the lane change content at a position visually recognized on the destination lane side with respect to the estimated trajectory content.

6. The display control device according to claim 1 , wherein
when an execution section of the lane change by the lane change control unit is within an angle of view of the head-up display, the display control unit displays the lane change content to be superimposed on a road surface including at least a part of the execution section.

7. The display control device according to claim 6 , wherein
when the execution section is outside the angle of view, the display control unit displays a change standby content indicating that the lane change is to be performed in a mode different from the lane change content that is displayed when the execution section is within the angle of view.

8. The display control device according to claim 7 , wherein
the display control unit displays the change standby content at a position that does not overlap with the estimated trajectory content.

9. A display control device for a vehicle to control a display on a head-up display, the display control device comprising:
a control information acquisition unit that acquires driving control information related to a driving control of the vehicle, from a lane keeping control unit that controls an in-lane traveling of the vehicle to cause the vehicle to travel in a lane;
a change information acquisition unit that acquires lane change information related to a lane change of the vehicle, from a lane change control unit that controls the lane change of the vehicle; and
a display control unit that displays an estimated trajectory content indicating an estimated trajectory of the in-lane traveling to be superimposed on a road surface as a superimposition target, based on the driving control information, wherein
in response to acquiring the lane change information during the in-lane traveling, the display control unit displays a lane change content indicating an estimated trajectory of the lane change together with the estimated trajectory content, based on the lane change information,
the lane change information includes on-operation information indicating input of an on operation instructing the lane change control unit to perform the lane change, and
the display control unit displays a response notification content for notifying an acceptance of the on operation together with the estimated trajectory content.

10. A display control device for a vehicle to control a display on a head-up display, the display control device comprising:
a control information acquisition unit that acquires driving control information related to a driving control of the vehicle, from a lane keeping control unit that controls an in-lane traveling of the vehicle to cause the vehicle to travel in a lane;
a change information acquisition unit that acquires lane change information related to a lane change of the vehicle, from a lane change control unit that controls the lane change of the vehicle; and
a display control unit that displays an estimated trajectory content indicating an estimated trajectory of the in-lane traveling to be superimposed on a road surface as a superimposition target, based on the driving control information, wherein
in response to acquiring the lane change information during the in-lane traveling, the display control unit begins to display a lane change content indicating an estimated trajectory of the lane change based on the lane change information, after terminating display of the estimated trajectory content, and
in response to recognizing interruption of the lane change based on the lane change information, the display control unit highlights the estimated trajectory content on the display by extending the estimated trajectory in a traveling direction in the lane beyond a transition point at which the lane change was to be performed.

11. The display control device according to claim 10 , wherein
the display control unit displays the lane change content at a position visually recognized on a far side with respect to the estimated trajectory content.

12. The display control device according to claim 10 , wherein
the lane change information includes destination lane information related to a destination lane to which the vehicle moves by the lane change, and
the display control unit displays the lane change content at a position visually recognized on the destination lane side with respect to the estimated trajectory content.

13. The display control device according to claim 10 , wherein
when an execution section of the lane change by the lane change control unit is within an angle of view of the head-up display, the display control unit displays the lane change content to be superimposed on a road surface including at least a part of the execution section.

14. The display control device according to claim 13 , wherein
when the execution section is outside the angle of view, the display control unit displays a change standby content indicating that the lane change is to be performed in a mode different from the lane change content that is displayed when the execution section is within the angle of view.

15. The display control device accordi
