Navigation apparatus displaying visual guidance
First Claim
1. A navigation apparatus for a vehicle, comprising:
- an indicating means including a display portion for displaying an image;
a map information acquiring means for acquiring map information;
a present position designating means for designating a present position of the vehicle;
a route acquiring means for acquiring a route to a destination; and
a navigating means for displaying, based on the acquired map information, a map image of a vicinity of the designated present position and the acquired route in superimposition in the display portion,wherein when a guidance point distance between the present position and a predetermined guidance point is smaller than a predetermined arrow display start distance, the navigating means is configured to superimpose, on the displayed route, a moving arrow which includes an arrowhead and a line between the arrowhead and the present position, the arrowhead moving from a start point to an end point along the route, the end point being a predetermined first distance ahead of the present position along the route, the start point being a predetermined second distance smaller than the first distance ahead of the present position along the route.

Abstract
A navigation apparatus for a vehicle displays, based on map information, a map image for vicinity of a present position of the vehicle and a guidance route in superimposition in a display device. An end point relative to a moving arrow is defined as being a predetermined first distance ahead of the present position along the route; a start point is defined as being a predetermined second distance smaller than the first distance ahead of the present position along the route. The navigation apparatus is further configured to superimpose, on the displayed route, the moving arrow which includes an arrowhead and a line between the arrowhead and the present position, such that the arrowhead moves from the start point to the end point along the route when a distance to a nearest guidance point is smaller than a predetermined distance.

10. A method for navigating a vehicle, the method comprising:
-
displaying, based on map information, a map image of a vicinity of a present position of the vehicle and a guidance route in superimposition in a display device; defining an end point relative to a moving arrow as being a predetermined first distance ahead of the present position along the guidance route; defining a start point relative to the moving arrow as being a predetermined second distance smaller than the first distance ahead of the present position along the guidance route; and superimposing, on the displayed guidance route, the moving arrow which includes an arrowhead and a line between the arrowhead and the present position, such as the arrowhead moves from the start point to the end point along the guidance route when a guidance point distance between the present position and a predetermined guidance point is smaller than a predetermined arrow display start distance.
