Abstract

In a display control device for a head-up display of a vehicle, a schedule notification content indicating a fulfillment schedule of a lane change is displayed on a road surface in a foreground in a superimposing manner. When the schedule notification content overreaches an angle of view, a non-superimposition content indicating the fulfillment schedule of the lane change independent of a superimposition target may be displayed, or the schedule notification content may be hidden. In a case where an arrow-shaped schedule notification content, having a tip portion indicating an adjacent lane as a destination of the lane change, is displayed in a superimposing manner on a road surface in the foreground, when the tip portion of the schedule notification content in a reference shape overreaches the angle of view, the schedule notification content may be transformed so that the tip portion is positioned within the angle of view.

First claim

What is claimed is:

1 . A display control device for a vehicle to control a head-up display to display a content in a superimposing manner, the display control device comprising:
an information acquisition unit that acquires lane change information about 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 a schedule notification content, indicating a fulfillment schedule of the lane change made by the lane change control unit, to be superimposed on a road surface in a foreground based on the lane change information, wherein, when the schedule notification content overreaches an angle of view of the head-up display, the display control unit displays a non-superimposition content that indicates the fulfillment schedule of the lane change independent of a superimposition target.

2 . The display control device according to claim 1 ,
wherein, when the schedule notification content overreaches the angle of view, the display control unit hides the schedule notification content and displays the non-superimposition content.

3 . The display control device according to claim 1 ,
wherein the display control unit displays the schedule notification content shaped in an arrow indicating an estimated trace of the vehicle; and wherein, when a tip portion of the schedule notification content is positioned within the angle of view, the display control unit continues displaying the schedule notification content.

4 . The display control device according to claim 1 ,
wherein the information acquisition unit acquires on-operation information associated with an on-operation instructing the lane change control unit to fulfill the lane change; and wherein the display control unit starts displaying the non-superimposition content based on the on-operation information acquired by the information acquisition unit.

5 . The display control device according to claim 1 ,
wherein, when the lane change made by the lane change control unit remains in an execution state, the display control unit displays the schedule notification content to be superimposed in a range ahead of a movement start point to start movement to a destination lane on a road surface of the destination lane according to the lane change.

6 . The display control device according to claim 5 ,
wherein, before the lane change enters the execution state, the display control unit displays a pre-notification content in a mode associated with the schedule notification content to be superimposed on substantially an entire road surface of the destination lane included in the angle of view.

7 . The display control device according to claim 1 ,
wherein the display control unit determines that the schedule notification content overreaches the angle of view when a ratio of an overlap region, overlapping an adjacent lane as a destination of the lane change, to an entire region in the angle of view exceeds a predetermined value.

8 . The display control device according to claim 1 ,
wherein the display control unit determines that the schedule notification content overreaches the angle of view when an outer lane line, which is one of lane lines on both sides of an adjacent lane as a destination of the lane change and being distant from the vehicle, is positioned outside the angle of view.

9 . The display control device according to claim 1 ,
wherein the vehicle has a driver's seat and a passenger seat installed to be placed in a horizontal direction of the vehicle; wherein the display control unit determines that the schedule notification content does not overreach the angle of view when an adjacent lane near the driver's seat is assumed to be a destination of the lane change; and wherein the display control unit determines that the schedule notification content overreaches the angle of view when an adjacent lane near the passenger seat is assumed to be a destination of the lane change.

10 . A display control device for a vehicle to control a head-up display to display a content in a superimposing manner, the display control device comprising:
an information acquisition unit that acquires lane change information about 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 a schedule notification content using a road surface in a foreground as a superimposition target and a non-superimposition content independent of the superimposition target, as the content indicating a fulfillment schedule of the lane change made by the lane change control unit, wherein, when the schedule notification content overreaches an angle of view of the head-up display, the display control unit hides the schedule notification content.

11 . The display control device according to claim 10 ,
wherein the display control unit displays the schedule notification content shaped in an arrow indicating an estimated trace of the vehicle; and wherein, when a tip portion of the schedule notification content is positioned within the angle of view, the display control unit continues displaying the schedule notification content.

12 . The display control device according to claim 10 ,
wherein the information acquisition unit acquires on-operation information associated with an on-operation instructing the lane change control unit to fulfill the lane change; and wherein the display control unit starts displaying the non-superimposition content based on the on-operation information acquired by the information acquisition unit.

13 . The display control device according to claim 10 ,
wherein, when the lane change made by the lane change control unit remains in an execution state, the display control unit displays the schedule notification content to be superimposed in a range ahead of a movement start point to start movement to a destination lane on a road surface of the destination lane according to the lane change.

14 . The display control device according to claim 13 ,
wherein, before the lane change enters the execution state, the display control unit displays a pre-notification content in a mode associated with the schedule notification content to be superimposed on substantially an entire road surface of the destination lane included in the angle of view.

15 . The display control device according to claim 10 ,
wherein the display control unit determines that the schedule notification content overreaches the angle of view when a ratio of an overlap region, overlapping an adjacent lane as a destination of the lane change, to an entire region in the angle of view exceeds a predetermined value.

16 . The display control device according to claim 10 ,
wherein the display control unit determines that the schedule notification content overreaches the angle of view when an outer lane line, which is one of lane lines on both sides of an adjacent lane as a destination of the lane change and being distant from the vehicle, is positioned outside the angle of view.

17 . The display control device according to claim 10 ,
wherein the vehicle has a driver's seat and a passenger seat installed to be placed in a horizontal direction of the vehicle; wherein the display control unit determines that the schedule notification content does not overreach the angle of view when an adjacent lane near the driver's seat is assumed to be a destination of the lane change; and wherein the display control unit determines that the schedule notification content overreach
