Abstract

To provide a navigation system for a moving body useful to carry out delivery service operation. A delivery history is included in customer information, and a route guide including at least one past delivery destination point is generated. A method of navigating a movable body for a delivery service is also included.

Claims

1. A navigation system for a moving body, comprising:

initial setting means for setting a starting point and a destination point of a moving body in response to an operation starting instruction;

map information storing means for storing map information;

display map information generating means for generating display map information from said map information storing means;

route guide generating means for generating a route guide connecting said starting point and said destination point to each other;

display means for superimposing said route guide on said display map information for display; and

destination point history storing means for storing said destination point in a destination point history data base,

wherein said route guide generating means includes in said route guide at least one destination point from said destination point history database other than said destination point, said at least one other destination point being retrieved from said destination point history databse without being set by said initial setting means.

2. The navigation system for a moving body as claimed in claim 1, wherein said route guide generating means includes said at least one other destination point in one of an outward route from said starting point to said destination point and a backward route from said destination point to said starting point in said route guide.

3. The navigation system for a moving body as claimed in claim 2, wherein said route guide generating means selects one of said outward route and said backward route according to an input instruction.

4. The navigation system for a moving body as claimed in claim 3, wherein said destination point history database further includes related information corresponding to said at least one other destination point and said destination point, and said route guide generating means includes in said route guide at least one of said at least one other destination point selected on the basis of said related information.

5. The navigation system fora moving body as claimed in claim 4, wherein said related information is the time when the moving body arrived at a destination point, and said route guide generating means includes in said route guide at least one of said at least one destination point selected on the basis of time elapsed from said time to present time.

6. The navigation system for a moving body as claimed in claim 2, wherein said destination point history database further includes related information corresponding to said at least one other destination point and said destination point, and said route guide generating means includes in said route guide at least one of said at least one other destination point selected on the basis of said related information.

7. The navigation system for a moving body as claimed in claim 6, wherein said related information is the time when the moving body arrived at a destination point, and said route guide generating means includes in said route guide at least one of said at least one destination point selected on the basis of time elapsed from said time to present time.

8. The navigation system for a moving body as claimed in claim 1, wherein said destination point history database further includes related information corresponding to said at least one other destination point and said destination point, and said route guide generating means includes in said route guide at least one of said at least one other destination point selected on the basis of said related information.

9. The navigation system for a moving body as claimed in claim 8, wherein said related information is the time when the moving body arrived at a destination point, and said route guide generating means includes in said route guide at least one of said at least one destination point selected on the basis of time elapsed from said time to present time.

10. The navigation system as claimed in claim 1, wherein said at least one other destination point is retrieved by said route guide generating means on the basis of predetermined information regarding said at least one other destination point.

11. A method of navigating a moving body, comprising the steps of:

setting a starting point and a destination point of a moving body in response to an operation starting instruction;

storing map information;

generating display map information;

generating a route guide connecting said starting point and said destination point to each other;

superimposing said route guide on said display map information for display; and

storing said destination point in a destination point history database,

wherein said route guide includes at least one destination point from said destination point history database other than said destination point, said at least one other destination point being retrieved from said destination point history databse without being set in said step of setting.

12. The method of navigating a moving body as claimed in claim 11, wherein said step of generating a route guide further includes the step of generating said at least one other destination point in one of an outward route from said starting point to said destination point and a backward route from said destination point to said starting point in said route guide.

13. The method of navigating a moving body as claimed in claim 12, further comprising the step of selecting one of said outward route and said backward route according to an input instruction.

14. The method of navigating a moving body as claimed in claim 13, wherein said step of storing further includes the step of storing related information corresponding to said at least one other destination point and said destination point in said destination point history database, said method further comprising the step of selecting at least one of said at least one other destination point on the basis of said related information.

15. The method of navigating a moving body as claimed in claim 14, wherein said related information is the time when the moving body arrived at a destination point, said method further comprising the step of selecting at least one of said at least one destination point on the basis of time elapsed from said time to present time.

16. The method of navigating a moving body as claimed in claim 12, wherein said step of storing further includes the step of storing related information corresponding to said at least one other destination point and said destination point in said destination point history database, said method further comprising the step of selecting at least one of said at least one other destination point on the basis of said related information.

17. The method of navigating a moving body as claimed in claim 16, wherein said related information is the time when the moving body arrived at a destination point, said method further comprising the step of selecting at least one of said at least one destination point on the basis of time elapsed from said time to present time.

18. The method of navigating a moving body as claimed in claim 11, wherein said step of storing further includes the step of storing related information corresponding to said at least one other destination point and said destination point in said destination point history database, said method further comprising the step of selecting at least one of said at least one other destination point on the basis of said related information.

19. The method of navigating a moving body as claimed in claim 18, wherein said related information is the time when the moving body arrived at a destination point, said method further comprising the step of selecting at least one of said at least one destination point on the basis of time elapsed from said time to present time.

20. The method of navigating a moving body as claimed in claim 11, wherein said step of generating a route guide includes the step of retrieving said at least one other destination point on the basis of predetermined information regarding said at least one other destination point.
