Abstract

A vehicle-mounted navigation system (1) including: a facility information acquisition device (21) which acquires facility information, wherein the facility information is position information pertaining to the facilities located around the route; a facility selection device (22) which selects, from among the facilities recorded in the facility information, upon consideration of the vehicle'"'"'s travel direction, facilities whose landmarks are to be displayed on a display section (4); and a landmark display device which displays, on the display section (4), landmarks of the facilities selected by the facility selection device (22) on the basis of the facility information.

Claims

1. A vehicle-mounted navigation system which detects the current position and direction of travel of a vehicle, retrieves a route to a set destination, guides the vehicle to the destination along the route, and displays landmarks assigned to facilities located around the route, the system comprising:

a facility information acquisition device which acquires facility information, wherein the facility information is position information pertaining to the facilities located around the route;

a facility selection device which selects, from among the facilities recorded in the facility information, upon consideration of the vehicle'"'"'s travel direction, facilities whose landmarks are to be displayed on a display section; and

a landmark display device, including the display section, which displays landmarks of the facilities selected by the facility selection device.

2. The vehicle-mounted navigation system as defined in claim 1, wherein, in the case of left-side driving, the facility selection device does not select facilities located on the right side with respect to the vehicle'"'"'s travel direction.

4. The vehicle-mounted navigation system as defined in claim 1, wherein the landmark display device displays landmarks which are representative of the type of facility designated thereby.

5. The vehicle mounted navigation system as defined in claim 1, wherein said facility selection device does not select for display, facilities whose landmarks are located rearward with respect to the vehicle'"'"'s travel direction.

3. A vehicle-mounted navigation system which detects the current position and direction of travel of a vehicle, retrieves a route to a set destination, guides the vehicle to the destination along the route, and displays landmarks assigned to facilities located around the route, the system comprising:

a facility information acquisition device which acquires facility information, wherein facility information is position information pertaining to the facilities located around the route;

a facility selection device which selects, from among the facilities recorded in the facility information, upon consideration of the vehicle'"'"'s travel direction, facilities whose landmarks are to be displayed on a display section; and

a landmark display device, including the display section, which displays landmarks of the facility selected by the facility selection device;

wherein in the case of right-side driving, the facility selection device does not select facilities located on the left side with respect to the vehicle'"'"'s travel direction.

6. A computer readable medium having recorded thereon a processing program for use with a vehicle-mounted navigation system, which system detects the current position and direction of travel of a vehicle, retrieves a route to a set destination, guides the vehicle to the destination along the route, and displays landmarks assigned to facilities located around the route, the program comprising:

a facility information acquisition processing routine for acquiring facility information, wherein the facility information is position information pertaining to the facilities located around the route;

a facility selection processing routine for selecting, from among the facilities recorded in the facility information, upon consideration of the vehicle'"'"'s travel direction, facilities whose landmarks are to be displayed on a display section; and

a landmark display processing routine for displaying, on the display section, landmarks of the facilities selected by the facility selection processing routine.

7. The computer readable medium for use with a vehicle-mounted navigation system as defined in claim 6, wherein, in the case of left-side driving, the facility selection processing routine does not select facilities located on the right side with respect to the vehicle'"'"'s travel direction.

9. The computer readable medium for use with a vehicle-mounted navigation system as defined in claim 6, wherein the landmark display processing routine displays landmarks which are representative of the type of facility designated thereby.

10. The computer readable medium for use with a vehicle mounted navigation system as defined in claim 6, wherein said facility selection processing routine does not select for display, facilities whose landmarks are located rearward with respect to the vehicle'"'"'s travel direction.

8. A computer readable medium having recorded thereon a processing program for use with a vehicle-mounted navigation system, which system detects the current position and direction of travel of a vehicle, retrieves a route to a set destination, guides the vehicle to the destination along the route, and displays landmarks assigned to facilities located around the route, the program comprising:

a facility information acquisition processing routine for acquiring facility information, wherein the facility information is position information pertaining to the facilities located around the route;

a facility selection processing routine for selecting, from among the facilities recorded in the facility information, upon consideration of the vehicle'"'"'s travel direction, facilities whose landmarks are to be displayed on a display section;

a landmark display processing routine for displaying, on the display section, landmarks of the facilities selected by the facility selection processing routine; and

a computer readable medium wherein in the case of right-side driving, the facility selection processing routine does not select facilities located on the left side with respect to the vehicle'"'"'s travel direction.
