Abstract

A head-up display apparatus for a vehicle is configured to output a display that has a convex shape in an upward direction as a whole such that a width of the display in a left/right direction, when the display is viewed from a predetermined view point, indicates a width of the vehicle. The image includes a meter that indicates an amount of a predetermined parameter.

Claims

1. A head-up display apparatus for a vehicle, the head-up display apparatus being configured to output an image whose shape is convex upwardly as a whole such that a width of the image in a left/right direction, when the image is viewed from a predetermined view point, indicates a width of the vehicle.

2. The head-up display apparatus for the vehicle of claim 1, wherein the image includes a meter that indicates an amount of a predetermined parameter that is related to a state of the vehicle or a traveling state.

3. The head-up display apparatus for the vehicle of claim 1, wherein the head-up display apparatus is configured to vary an output position of the image in the left/right direction based on sensor information, the sensor information representing at least one of a direction of the vehicle, and a position of the vehicle with respect to a lane maker.

4. The head-up display apparatus for the vehicle of claim 3, wherein the head-up display apparatus is configured to determine the output position of the image in the left/right direction such that a center of the image in the left/right direction is on a center line of the vehicle in a front/back direction.

5. The head-up display apparatus for the vehicle of claim 3, wherein the head-up display apparatus is configured to vary the output position of the image in the left/right direction based on steering angle information that represents the direction of the vehicle.

6. The head-up display apparatus for the vehicle of claim 5, wherein the head-up display apparatus is configured to vary the output position of the image in the left/right direction such that the image is between the predicted trajectories of left and right of the vehicle and equally away from the predicted trajectories in the left/right direction, the predicted trajectories being varied according to the steering angle.

7. The head-up display apparatus for the vehicle of claim 1, wherein the head-up display apparatus is configured to vary the output position of the image in an up/down direction according to a vehicle speed.

8. The head-up display apparatus for the vehicle of claim 1, wherein the shape of the image includes an arc and convex shape in an upward direction, or a shape obtained by removing a lower base from a trapezoid shape whose lower base is longer than an upper base.

9. The head-up display apparatus for the vehicle of claim 1, wherein the output position of the image in the left/right direction is varied without an orientation with respect to a horizontal direction being varied.

10. The head-up display apparatus for the vehicle of claim 1, wherein the shape of the image is substantially symmetric with respect to the center thereof in the left/right direction.
