A facility information display control unit which displays.
[0016]
Here, the road identifier, the lane information, the facility information, and the intersection identifier in the present embodiment will be described with reference to FIGS. The road identifier uses a road number or a road name such as “Road 1 (Plaza Dori)”, “Road 2 (Higashi Dori)”, “Road 3 (Yamate Trunk Line)”, “Road 4 (Sakura Dori)”, and the like. The information uses direction information such as “bound to the north”, “bound to the south”, “bound to the east”, and “bound to the west”, and the intersection identifier is “intersection 1 (plaza north)”, “intersection 2 (plaza south)”, "Intersection 3 (east 1-chome)", "intersection 4 (east 2-chome)", and "intersection 5 (T-shaped Katsuji)" are used.

[0017]
The road information of the map database 204 is stored as vector data by dividing the route from the start point to the end point of each road by a predetermined method, and stores the road identifier of the moving body based on the current position and the traveling direction of the moving object. It is assumed that lane information can be searched. Also, the intersection information in the map database can be searched for a next passing intersection identifier from the current position of the moving object, the road identifier, and the lane information.
[0018]
In addition to these pieces of information, the map database 204 stores the location information of intersections, the road identifiers entering and exiting each intersection, and road attributes such as road width / one-way / toll road. In the facility information database 206, the nearest intersection refers to an intersection on both sides closest to the facility on the road facing the facility.
[0019]
For example, in facility 1 in FIG. 8, "intersection 1" and "intersection 2" are the nearest intersections. When the road facing the facility is a narrow street (a narrow road having a road width of less than 4 m), the nearest intersection may be an intersection on both sides of the general road closest to a point where the general road enters the narrow street.
[0020]
For example, in the case of the facility 2 in FIG. 8, "intersection 1" and "intersection 3" may be set as the nearest intersections. If the road facing the facility is one-way, only the intersection on the approachable side is set as the nearest intersection. In the case of the facility 4 in FIG. 8, since the vehicle can enter only from the "intersection 2" side, the nearest intersection is only "intersection 2".
[0021]
The overall operation of the system configured as described above will be described with reference to the flowchart of FIG.

To obtain the intersection identifier. Here, assuming that there is a moving object at the position A in FIG. 8, an intersection identifier “intersection 2” is obtained from “road 1” and “northbound”.
[0042]
<Step ab3>
Using the intersection identifier obtained in step ab2 and the category set in step aa3 in FIG. 4 as search conditions, a facility name to be presented to the user is extracted from the facility information database 206. Here, the facility information database 206 storing the data shown in FIG. 9 is searched using the intersection identifier = “intersection 2” and the category = “restaurant” as search conditions. It is assumed that the search result is obtained in FIG. In FIG. 10, items that match the conditions are shown in reverse video.
[0043]
<Step ab4>
Based on the search result obtained in step ab3, intersection guidance display data to be displayed before passing through the predicted intersection is created, and a condition for displaying this data is a predetermined distance to the intersection, for example, a distance of 300 m. After setting, the process returns to the process of FIG. Here, among the facility information on the road on which the moving body is traveling, it is assumed that the facility information on the same side as the moving body when viewed from the next scheduled intersection is not included.
[0044]
