Abstract

A display control device is used in a vehicle to control a display of a head-up display The display control device acquires external information based on recognition of a traveling environment around the vehicle, and causes the head-up display to display a superimposition content for providing a route guidance to be superimposed on a foreground in a guidance area. Further, the display control device causes the head-up display to end a display of the superimposition content at a timing based on an end determination using at least the external information.

First claim

What is claimed is:

1. A display control device for a vehicle to control a head-up display, the vehicle being equipped with a navigation device for performing a route guidance, the display control device comprising:
a navigation information acquisition unit configured to acquire navigation information related to the route guidance performed by the navigation device;
an external information acquisition unit configured to acquire external information based on recognition of a traveling environment around the vehicle; and
a display control unit configured to cause the head-up display to display a superimposition content for providing a route guidance to be superimposed on a foreground in a guidance area where the route guidance by the navigation device is performed, wherein
the display control unit is configured to cause the head-up display to end a display of the superimposition content at a timing before the vehicle passes through the guidance area, based on an end determination using at least the external information, without using an end notification that notifies an end of the route guidance by the navigation device.

2. The display control device according to claim 1 , wherein
the guidance area includes an intersection where the vehicle is scheduled to make a left turn or a right turn.

3. The display control device according to claim 2 , wherein
the external information acquisition unit acquires, as the external information, intersection target information based on recognition of a target related to the intersection, and
the display control unit causes the head-up display to end the display of the superimposition content based on the end determination using the intersection target information.

4. The display control device according to claim 2 , wherein
in response to the intersection included in the guidance area being a predetermined complex intersection, the display control unit changes a condition for establishing the end determination so that a timing to end the display of the superimposition content is later than that when the intersection is not the complex intersection.

5. The display control device according to claim 2 , wherein
in response to the guidance area having a stop line before the intersection, the display control unit changes a condition for establishing the end determination so that a timing to end the display of the superimposition content is later than that in the guidance area without having the stop line.

6. The display control device according to claim 2 , wherein
in response to the vehicle being scheduled not to cross an oncoming lane in a right turn or a left turn at the intersection included in the guidance area, the display control unit changes a condition for establishing the end determination so that a timing to end the display of the superimposition content is later than that when the vehicle is scheduled to cross the oncoming lane at the intersection.

7. The display control device according to claim 1 , wherein
the guidance area includes a junction where the vehicle is scheduled to change lanes,
the external information acquisition unit is configured to acquire, as the external information, point target information based on recognition of a target related to the junction, and
the display control unit is configured to cause the head-up display to end the display of the superimposition content based on the end determination using the point target information.

8. The display control device according to claim 1 , wherein
the external information acquisition unit is configured to acquire, as the external information, edge position information obtained by detecting a road edge in the guidance area, and
the display control unit is configured to cause the head-up display to end the display of the superimposition content based on the end determination using the edge position information.

9. The display control device according to claim 1 , wherein
the display control unit is configured to change a condition for establishing the end determination according to a road shape in the guidance area.

10. The display control device according to claim 1 , wherein
the display control unit is configured to cause the head-up display to display a non-superimposition content for continuing the route guidance in a display period after the display of the superimposition content is ended, and
the display control unit is configured to change a mode of the non-superimposition content so as to lower a visibility of the non-superimposition content in the display period.

11. The display control device according to claim 1 , further comprising:
a map data acquisition unit configured to acquire low-precision map data and high-precision map data having an accuracy higher than that of the low-precision map data, as map data used in the display control unit to generate the superimposition content, wherein
the display control unit is configured to change a condition for establishing the end determination based on whether or not the high-precision map data is acquired.

12. The display control device according to claim 11 , wherein
when the superimposition content is generated by using the high-precision map data, the display control unit is configured to change a condition for establishing the end determination so that the display of the superimposition content is more difficult to end than that when the superimposition content is generated using the low-precision map data.

13. The display control device according to claim 1 , wherein
the external information acquisition unit is configured to acquire, as the external information, camera recognition information based on data captured by an in-vehicle camera mounted on the vehicle, and
when the superimposition content is generated by using the camera recognition data, the display control unit is configured to change a condition for establishing the end determination so that the display of the superimposition content is more difficult to end than when the superimposition content is generated without using the camera recognition data.

14. The display control device according to claim 1 , further comprising:
an operation information acquisition unit configured to acquire operation information related to an operation of an occupant of the vehicle, wherein
the display control unit is configured to cause the head-up display to end the display of the superimposition content based on the end determination using the operation information in addition to the external information.

15. A display control device for a vehicle to control a screen display and a head-up display, the display control device comprising:
an external information acquisition unit configured to acquire external information based on recognition of a traveling environment around the vehicle; and
a display control unit configured to cause the head-up display to display a superimposition content for providing a route guidance to be superimposed on a foreground in a guidance area where the display control unit causes the screen display to display a route guidance image, wherein
the display control unit is configured to cause the head-up display to end a display of the superimposition content at a timing before the display control unit causes the screen display to end a display of the route guidance image and before the vehicle passes through the guidance area, based on an end determination using at least the external information.

16. A display control device for a vehicle to control a head-up display, the vehicle being equipped with a navigation device for pe
