Abstract

Implementations of an in-vehicle display system may include: a first display device configured to irradiate a first area of a windshield of a vehicle with a first light constituting a first image and to display the first image as a virtual image of the first image in front of the first area; a second display device configured to display a second image as a real image in a second area of the windshield that is wider than the first area; and a control device configured to control the first display device and the second display device based on a travel state of the vehicle.

First claim

What is claimed is:

1. An in-vehicle display system comprising:
a first display device configured to irradiate, while a vehicle is operating in a manual driving mode, a first area of a windshield of the vehicle with a first light constituting a first image and to display the first image as a virtual image of the first image in front of the first area;
a second display device configured to display, while the vehicle is operating in an autonomous driving mode, a second image as a real image in a second area of the windshield that is wider than the first area; and
a control device configured to control the first display device and the second display device based on whether the vehicle is operating in the manual driving mode or the autonomous driving mode.

2. The in-vehicle display system according to claim 1 , wherein, when switching the second image to the first image, the control device is configured to deform the second image so as to be included in the first area.

3. The in-vehicle display system according to claim 1 , wherein, when switching the second image to the first image, the control device is configured to zoom-out the second image.

4. The in-vehicle display system according to claim 1 , wherein, when switching the second image to the first image, the control device is configured to display a dummy image of an object included in a front field of view as the second image.

5. The in-vehicle display system according to claim 1 , wherein, when switching the second image to the first image, the control device is configured to cross-fade the second image and the first image.

6. The in-vehicle display system according to claim 1 , wherein the first display device includes:
a first radiation unit configured to radiate the first light; and
a first optical system configured to reflect the first light radiated by the first radiation unit and to perform irradiation toward the first area at a predetermined angle.

7. The in-vehicle display system according to claim 1 , wherein the second display device includes:
a second radiation unit configured to radiate a second light constituting the second image; and
a second optical system configured to reflect the second light radiated by the second radiation unit and to perform irradiation toward the second area at a predetermined angle.

8. The in-vehicle display system according to claim 7 , wherein the second area is an area where a transparent film screen is provided or an area where dew condensation occurs on the windshield.

9. The in-vehicle display system according to claim 1 , wherein the second display device includes:
a transparent display that is provided in the second area; and
a display control unit configured to control display of the transparent display.
