Vehicular display apparatus
First Claim
1. A vehicular display apparatus in a host vehicle, the vehicular display apparatus comprising:
- a display portion having a ring-shaped display area that represents a presence of a different vehicle that is distant from the host vehicle;
a direction specification processor to specify a direction indicating presence of the different vehicle with reference to the host vehicle based on position information about the host vehicle and the different vehicle;
a distance specification processor to specify a distance between the different vehicle and the host vehicle based on the position information about the host vehicle and the different vehicle; and
a display control processor to display a displayed part of the ring-shaped display area, the displayed part having a center that is fixed based on the direction specified by the direction specification processor, the displayed part having a length that is fixed based on the distance specified by the distance specification processor such that the length increases as the distance between the different vehicle and the host vehicle decreases.

Abstract
A vehicular display apparatus in a host vehicle is provided with a display output portion including a ring-shaped light-emitting area that represents presence of a different vehicle. A direction specification processor specifies a direction indicating presence of the different vehicle with reference to the host vehicle based on position information about the host vehicle and the different vehicle. A distance specification processor specifies a distance between the host vehicle and the different vehicle based on position information about the host vehicle and the different vehicle. A display control processor displays part of the light-emitting area so that the displayed part is positioned in a direction specified by the direction specification processor and has a length based on a distance specified by the distance specification processor.

9. A vehicular display apparatus in a host vehicle, the vehicular display apparatus comprising:
-
a display portion having a ring-shaped display area that represents a presence of a different vehicle that is distant from the host vehicle; a direction specification processor to specify a direction indicating the presence of the different vehicle with reference to the host vehicle based on position information about the host vehicle and the different vehicle; a distance specification processor to specify a distance between the different vehicle and the host vehicle based on the position information about the host vehicle and the different vehicle; and a display control processor to define (i) a first coverage circle of the host vehicle with a first predetermined radius and a first center corresponding to a present position of the host vehicle and (ii) a second coverage circle of the different vehicle with a second predetermined radius and a second center corresponding to a present position of the different vehicle, based on the position information about the host vehicle and the different vehicle, draw both tangent lines relative to the second coverage circle of the different vehicle from the first center of the first coverage circle of the host vehicle, finding a divided circle of the first coverage circle area divided by both the tangent lines, and highlight a displayed arc part of the ring-shaped display area, the displayed arc part having a center that is based on the direction specified by the direction specification processor, the displayed arc part having a length that is fixed based on the divided circle of the first coverage circle divided by both the tangent lines.
