Abstract

A vehicle navigation apparatus that is capable of quickly providing information about a new facility to a user when the new facility is set up. The vehicle navigation apparatus includes information about a newly added facility. When a vehicle is approaching the new facility, an image representing the existence of the new facility is displayed on a map.

Claims

1. A method of vehicle navigation comprising the acts of:

providing a storage medium in a vehicle, the storage medium operable to store map data and facility data;

providing a vehicle position detector operable to detect a present position of a vehicle;

providing a display device;

providing a communications device operable to establish communication connection with a data transmission center outside the vehicle;

reading map data stored in the storage medium based on the vehicle position detected by the vehicle position detector to display a map on the display device;

updating map data and facility data stored in the storage medium based on other map data and other facility data obtained from the data transmission center via the communications device, the other map data and other facility data comprising data regarding a recently established facility;

displaying a unique image representing the existence of the recently established facility on the map on the display device when the vehicle approaches the recently established facility, wherein the unique image distinguishes the recently established facility on the map from facilities that are not recently established;

saving information about the recently established facility in a temporary storage area of the storage medium; and

deleting information about the recently established facility stored in the temporary storage area after a specified period of time has elapsed;

wherein the recently established facility is displayed irrespective of a request regarding the recently established facility.

2. The vehicle navigation method of claim 1, wherein obtaining other map data and facility data comprises obtaining map data and facility data corresponding to an area within a predetermined range with an arbitrary point centered from said data transmission center via said communications device.

3. The vehicle navigation method of claim 1, wherein the act of displaying an image representing the existence of the recently established facility on the map on the display device comprises displaying an opening date of the recently established facility, an image representing a facility type of the recently established facility, a simple arrow image representing a route from the vehicle to the recently established facility, or a distance from the vehicle to the recently established facility.

4. The vehicle navigation method of claim 1, further comprising the act of announcing the existence of the recently established facility by voice.

5. The vehicle navigation method of claim 1, further comprising the act of deleting the image representing the existence of the recently established facility when vehicle travel has exceeded a predetermined distance or when a predetermined period of time has elapsed.

6. The vehicle navigation method of claim 1, wherein the image representing the existence of the recently established facility is of a pre-registered type from among the facility data obtained from said data transmission center.

7. The vehicle navigation method of claim 1, wherein the image representing the existence of the recently established facility is displayed a plurality of times as the vehicle travels.

8. The vehicle navigation method of claim 1, wherein the image representing the existence of the recently established facility is displayed every time a distance between the vehicle and the recently established facility reaches a predetermined distance.

9. The vehicle navigation method of claim 1 further comprising the acts of searching for a guidance route to the recently established facility, and guiding the vehicle to the recently established facility along the guidance route.

10. A method of guiding a vehicle to a recently established facility in a vehicle navigation apparatus, comprising the acts of:

obtaining facility data about a recently established facility from a data transmission center;

displaying a unique image representing existence of the recently established facility on the map image when the vehicle is approaching the recently established facility, wherein the unique image distinguishes the recently established facility on the map image from facilities that are not recently established;

saving information about the recently established facility in a temporary storage area of a storage medium; and

deleting information about the recently established facility stored in the temporary storage area after a specified period of time has elapsed;

wherein the recently established facility is displayed irrespective of a request regarding the recently established facility.

11. The method of claim 10, wherein the image representing the existence of the recently established facility includes an opening date of the recently established facility, an image representing a facility type of the recently established facility, a simple arrow image representing a route from the vehicle to the recently established facility, or a distance from the vehicle to the recently established facility.

12. The method of claim 10, wherein the act of displaying the image representing the existence of recently established facility is performed a plurality of times as the vehicle travels.

13. The method of claim 10, further comprising the acts of searching for a guidance route from the vehicle to the recently established facility when the image representing the existence of the recently established facility is designated by a user, and guiding the vehicle to recently established facility along the guidance route.
