Abstract

A navigation apparatus includes: a route search unit that obtains a route to take from a start point to a destination; a vehicle position detection unit that detects a vehicle position; and a route guidance unit that provides route guidance based upon the obtained route. And the route guidance unit displays the route within a predetermined range from the vehicle position as a straight bar together with the vehicle position, displays an intersection indicator on the straight bar in correspondence to an intersection present within the predetermined range on the route and varies display mode when displaying the intersection indicator depending upon whether the intersection is a guidance-requiring intersection at which the route guidance is provided or a non-guidance intersection at which the route guidance is not provided.

Claims

1. A navigation apparatus comprising:

a route search unit that obtains a route to take from a start point to a destination;

a vehicle position detection unit that detects a vehicle position; and

a route guidance unit that provides route guidance based upon the obtained route, wherein;

the route guidance unit displays the route within a predetermined range from the vehicle position as a straight bar different from a roadmap together with the vehicle position, displays an intersection indicator on the straight bar in correspondence to an intersection present within the predetermined range on the route and varies display mode when displaying the intersection indicator depending upon whether the intersection is a guidance-requiring intersection at which the route guidance is provided or a non-guidance intersection at which the route guidance is not provided.

2. A navigation apparatus according to claim 1, wherein:

the route guidance unit displays the intersection indicator so as to enable a user to determine whether or not traffic lights are present at the intersection.

3. A navigation apparatus according to claim 1, wherein:

the route guidance unit displays the vehicle position on the straight bar at a fixed position and shifts the intersection indicator as the vehicle moves.

4. A navigation apparatus according to claim 1, wherein:

the route guidance unit varies the display mode by changing a color used to display the intersection indicator.

5. A navigation apparatus according to claim 1, wherein:

the route guidance unit displays the intersection indicator on the straight bar at a position set in proportion to a distance from the vehicle position to the intersection.

6. A navigation apparatus according to claim 1, wherein:

the route guidance unit displays information related to lane corresponding to the intersection.

7. A navigation apparatus according to claim 6, wherein:

the route guidance unit displays the intersection indicator on the straight bar and the information related to lane with specific correlated indication regarding an intersection.

8. A navigation apparatus according to claim 1, wherein:

the route guidance unit displays the route as the straight bar even if the route turns at an intersection.

9. A navigation apparatus according to claim 1, wherein:

the route guidance unit displays the route as the straight bar simplified differently from a road map.

10. A navigation apparatus according to claim 1, wherein:

the route guidance unit displays the route as the straight bar always vertically on a screen.

11. A navigation apparatus comprising:

a route search unit that determines a route to take from a start point to a destination;

a vehicle position detection unit that detects a vehicle position; and

a route guidance unit that provides route guidance based upon the obtained route, wherein;

the route guidance unit displays the route within a predetermined range from the vehicle position as a straight bar together with the vehicle position, displays an intersection indicator on the straight bar in correspondence to an intersection present within the predetermined range on the route and varies display mode when displaying the intersection indicator depending upon whether or not there is lane information to be guided at the intersection.

12. A navigation apparatus according to claim 11, wherein:

the route guidance unit displays the intersection indicator so as to enable a user to determine whether or not traffic lights are present at the intersection.

13. A navigation apparatus according to claim 11, wherein:

the route guidance unit displays the vehicle position on the straight bar at a fixed position and shifts the intersection indicator as the vehicle moves.

14. A navigation apparatus according to claim 11, wherein:

the route guidance unit varies the display mode by changing a color used to display the intersection indicator.

15. A navigation apparatus according to claim 11, wherein:

the route guidance unit displays the intersection indicator on the straight bar at a position set in proportion to a distance from the vehicle position to the intersection.

16. A navigation apparatus according to claim 11, wherein:

the route guidance unit displays information related to lane corresponding to the intersection.

17. A navigation apparatus according to claim 16, wherein:

the route guidance unit displays the intersection indicator on the straight bar and the information related to lane with specific correlated indication regarding an intersection.

18. A computer product comprising a computer-readable medium having stored thereon a control program that executes functions of:

obtaining a route to take from a start point to a destination;

detecting a vehicle position;

providing route guidance based upon the obtained route;

displaying the route within a predetermined range from the vehicle position as a straight bar different from a roadmap together with the vehicle position;

displaying an intersection indicator on the straight bar in correspondence to an intersection present within the predetermined range on the route; and

varying a display mode when displaying the intersection indicator depending upon whether the intersection is a guidance-requiring intersection at which the route guidance is provided or a non-guidance intersection at which the route guidance is not provided.

19. A computer product comprising a computer-readable medium having stored thereon a control program that executes functions of:

determining a route to take from a start point to a destination;

detecting a vehicle position;

providing route guidance based upon the determined route;

displaying the route within a predetermined range from the vehicle position as a straight bar together with the vehicle position;

displaying an intersection indicator on the straight bar in correspondence to an intersection present within the predetermined range on the route; and

varying a display mode when displaying the intersection indicator depending upon whether or not there is lane information to be guided at the intersection.
