Abstract

A display apparatus for a vehicle includes a virtual image display device, a detection device, and a picture control device. The virtual image display device emits predetermined light to permit a windshield or a combiner to reflect the predetermined light towards an eye of a driver. The emitted predetermined light is to display a picture. The virtual image display device displays the picture in a displayed area as a virtual image; the picture appears ahead of the vehicle. The detection device detects a target that is an obstacle or an intersection. The picture control device displays the picture to appear below the target in the displayed area, and then moves the picture to a position corresponding to the target apparently while decreasing at least a width of the picture.

Claims

1. A display apparatus for a vehicle, comprising:

a virtual image display device configured to emit predetermined light to permit a windshield or a combiner to reflect the predetermined light towards an eye of a driver, the emitted predetermined light being to display a picture, the virtual image display device displaying the picture in a displayed area as a virtual image, the picture appearing ahead of the vehicle;

a detection device configured to detect a target that is an obstacle or an intersection; and

a picture control device configured

to display the picture to appear below the target in the displayed area, and

to then move the picture to a position corresponding to the target apparently while decreasing at least a width of the picture.

2. The display apparatus according to claim 1, wherein:

the picture is a line segment extended horizontally; and

the picture control device decreases a length of the line segment when moving the line segment.

3. The display apparatus according to claim 1, wherein:

the picture is approximately rectangular; and

the picture control device performs deformation of the picture to permit a degree of the deformation to increase as the picture is moved.

4. The display apparatus according to claim 1, wherein

a movement speed of the picture becomes smaller as the picture moves higher in the displayed area.

5. The display apparatus according to claim 1, further comprising:

a road recognition device configured to recognize a road where the vehicle heads,

wherein the picture control device moves the picture to permit the eye of the driver to see the picture moving along the road.

6. The display apparatus according to claim 1, wherein

the picture control device raises a brightness of the picture when the picture comes to the position corresponding to the target apparently.

7. The display apparatus according to claim 1, further comprising:

a vehicle speed detection device configured to detect a vehicle speed of the vehicle,

wherein the picture control device changes a movement speed of the picture depending on the vehicle speed of the vehicle.

8. The display apparatus according to claim 1, further comprising:

a road surface color detection device configured to detect a color of a road surface ahead of the vehicle,

wherein the picture control device changes a color of the picture depending on the color of the road surface ahead of the vehicle.

19. The display apparatus according to claim 1, further comprising

a driver picture acquisition device configured to acquire a driver picture including a viewpoint of the driver;

and

a viewpoint detection device configured to detect a position of the viewpoint based on the driver picture,

wherein the picture control device changes a display position of the picture depending on the position of the viewpoint detected by the viewpoint detection device.

9. A display apparatus for a vehicle, comprising:

a virtual image display device configured to emit predetermined light to permit a windshield or a combiner to reflect the predetermined light towards an eye of a driver, the emitted predetermined light being to display a picture, the virtual image display device displaying the picture in a displayed area as a virtual image, the picture appearing ahead of the vehicle;

a detection device configured to detect a target that is an obstacle or an intersection; and

a picture control device configured

to display the picture to appear below the target in the displayed area, and

to then move the picture to a position corresponding to the target along a locus of an object that is assumed to be thrown towards the target.

10. The display apparatus according to claim 9, wherein

the picture control device sets a movement speed of the picture greater as a distance to the target is longer.

11. The display apparatus according to claim 9, wherein:

the picture control device displays a wave ring picture, which expresses a wave ring that arises when the picture is assumed to fall on a water surface, when the picture is moved to the position corresponding to the target apparently; and

the wave ring is smaller as a distance to the target is longer.

12. The display apparatus according to claim 9, wherein:

the picture control device sets a magnitude of the picture smaller within a range up to a predetermined lower limit as a distance to the target becomes smaller.

13. The display apparatus according to claim 9, further comprising:

a vehicle speed detection device configured to detect a vehicle speed of the vehicle,

wherein the picture control device changes a movement speed of the picture depending on the vehicle speed of the vehicle.

14. The display apparatus according to claim 9, further comprising:

a road surface color detection device configured to detect a color of a road surface ahead of the vehicle,

wherein the picture control device changes a color of the picture depending on the color of the road surface ahead of the vehicle.

15. A display apparatus for a vehicle, comprising:

a virtual image display device configured to emit predetermined light to permit a windshield or a combiner to reflect the predetermined light towards an eye of a driver, the emitted predetermined light being to display a picture, the virtual image display device displaying the picture in a displayed area as a virtual image, the picture appearing ahead of the vehicle;

a detection device configured to detect a target that is an obstacle or an intersection;

a distance estimation device configured to estimate a distance to the target;

a picture control device configured

to display the picture to appear at a position corresponding to the target, the picture including a plurality of picture elements that separate from each other with separation intervals, and

to then decrease the separation intervals of the picture elements to permit the plurality of picture elements of the picture to be integrated into an integrated picture; and

an interval setting device configured to set an initial value of the separation interval of the picture elements depending on a distance to the target.

16. The display apparatus according to claim 15, wherein

the picture including the plurality of picture elements represents two-dimensionally a plurality of objects that are assumed to be in a three-dimensional space, the plurality of objects having identical sizes and separating from each other with equal separation intervals in three directions that are orthogonal to each other in the three-dimensional space.

17. The display apparatus according to claim 15, further comprising:

a road surface color detection device configured to detect a color of a road surface ahead of the vehicle,

wherein the picture control device changes a color of the picture and a color of the picture element depending on the color of the road surface ahead of the vehicle.

18. A display apparatus for a vehicle, comprising:

a virtual image display device configured to emit predetermined light to permit a windshield or a combiner to reflect the predetermined light towards an eye of a driver, the emitted predetermined light being to display a picture, the virtual image display device displaying the picture in a displayed area as a virtual image, the picture appearing ahead of the vehicle;
