Vehicular display device
A vehicular display device configured to display a guide route to a destination of a host vehicle includes a navigation device configured to calculate the guide route, a display controller configured to draw an arrow having a shaft with an arrowhead at one end of the shaft, as a guide figure for guidance along the guide route calculated by the navigation device, such that the arrow is shaped as a three-dimensional object in which one surface of the arrow is a continuous flat surface from the shaft to the arrowhead and the other surface of the arrow includes a first portion with a first width having a first height, and a second portion with a second width smaller than the first width and having a second height smaller than the first height, and a display configured to display an image drawn by the display controller in a display area.
1. A vehicular display device configured to display a guide route to a destination of a host vehicle, the vehicular display device comprising:
a navigation device configured to calculate the guide route;
a display controller configured to acquire the guide route from the navigation device and draw an arrow based on the guide route,
wherein the guide route includes a start position, a direction, and a length of the arrow,
wherein the arrow has a shaft with an arrowhead at one end of the shaft and a three-dimensional shape with one or more dimensions calculated based on the guide route,
wherein one surface of the arrow is a continuous flat surface from the shaft to the arrowhead and an other surface of the arrow includes a larger width portion having a larger height and a smaller width portion having a smaller height; and
a display configured to display an image drawn by the display controller in a display area provided to overlap a position of a windshield,
wherein the display controller is configured to calculate, based on the guide route, an arrangement of the arrow drawn by lines superimposed on the guide route, convert the arrangement to draw the arrow in the three-dimensional shape, and display the arrow such that the one surface appears to be superimposed on a ground.
2. The vehicular display device according to claim 1 , wherein the display controller is configured to draw the arrow in a three-dimensional arch shape where, within both the shaft and the arrowhead, a height of the arrow decreases in a curved line from a center of the arrow in the width direction towards both edges of the arrow.
3. A vehicular display device configured to display a guide route to a destination of a host vehicle, the vehicular display device comprising:
a navigation device configured to calculate the guide route;
a display controller configured to acquire the guide route from the navigation device and draw an arrow based on the guide route,
wherein the guide route includes a start position, a direction, and a length of the arrow,
wherein the arrow has a shaft with an arrowhead at one end of the shaft and a three-dimensional shape with one or more dimensions calculated based on the guide route,
wherein one surface of the arrow is a continuous flat surface from the shaft to the arrowhead and an other surface of the arrow includes a larger width portion having a larger height and a smaller width portion having a smaller height; and
a display configured to display an image drawn by the display controller in a display area provided to overlap a position of a windshield,
wherein the display controller is configured to calculate, based on the guide route, an arrangement of the arrow drawn by lines superimposed on the guide route and convert the arrangement to draw the arrow in a three-dimensional ridge shape where, within both the shaft and the arrowhead, a height of the arrow decreases linearly from a center of the arrow in the width direction towards both edges of the arrow in the width direction.
4. A vehicular display device configured to display a guide route to a destination of a host vehicle, the vehicular display device comprising:
a navigation device configured to calculate the guide route;
a display controller configured to acquire the guide route from the navigation device and draw an arrow based on the guide route,
wherein the guide route includes a start position, a direction, and a length of the arrow,
wherein the arrow has a shaft with an arrowhead at one end of the shaft and a three-dimensional shape with one or more dimensions calculated based on the guide route,
wherein one surface of the arrow is a continuous flat surface from the shaft to the arrowhead and an other surface of the arrow includes a larger width portion having a larger height and a smaller width portion having a smaller height; and
a display configured to display an image drawn by the display controller in a display area provided to overlap a position of a windshield,
wherein the display controller is configured to calculate, based on the guide route, an arrangement of the arrow drawn by lines superimposed on the guide route and convert the arrangement to draw the arrow in a three-dimensional cockscomb shape, where, within both the shaft and the arrowhead, a line along a center of the arrow in the width direction is protruded to a height of the arrow while, away from the center of the arrow in the width direction, the height is constant.
5. The vehicular display device according to claim 1 , wherein the width of the shaft is constant in the continuous flat surface.
6. The vehicular display device according to claim 3 , wherein the width of the shaft is constant in the continuous flat surface.
7. The vehicular display device according to claim 4 , wherein the width of the shaft is constant in the continuous flat surface.
8. The vehicular display device according to claim 1 , wherein, when viewed orthogonally to the continuous flat surface, the arrowhead is triangular and the shaft is rectangular.
9. The vehicular display device according to claim 1 , wherein, in the continuous flat surface, the arrowhead is triangular and the shaft is rectangular.
10. The vehicular display device according to claim 3 , wherein, when viewed orthogonally to the continuous flat surface, the arrowhead is triangular and the shaft is rectangular.
11. The vehicular display device according to claim 3 , wherein, in the continuous flat surface, the arrowhead is triangular and the shaft is rectangular.
12. The vehicular display device according to claim 4 , wherein, when viewed orthogonally to the continuous flat surface, the arrowhead is triangular and the shaft is rectangular.
13. The vehicular display device according to claim 4 , wherein, in the continuous flat surface, the arrowhead is triangular and the shaft is rectangular.
