In this case, each part of the navigation device described above may be realized as a process embodied by a microprocessor executing a program prepared in advance. In this case, such a program may be provided to the navigation apparatus 1 via a recording medium or an appropriate communication path.

Next, FIG. 2 shows the contents of the map data stored in the map data storage unit 11.
As shown in the figure, the map data includes management data describing the version of the map data, route data, and basic map data representing the map.
The route data has a route record provided for each road. Each route record includes a route number that is an identifier of a road, a route type such as a highway, a national road, and a prefectural road, The route name of the road is described.

The basic map data includes a road unit representing a road network, a drawing unit representing a map image used for map display, and a facility unit storing usage information about various facilities.
The road unit is data representing a road map, and has a node table and a link table. Here, in the road unit, the road is expressed as a set of links that are straight lines, and the end point of each link is a node. In the node table, various information related to nodes such as the coordinates of each node is stored, and in the link table, various information related to links such as identification of nodes at both ends of each link are stored.

  Next, the facility unit has a facility record provided for each facility. Each facility record includes a facility number, which is a facility identification number, a facility such as a gas station, a restaurant, a junction, an interchange, a service area, or a parking area. A facility type that indicates the type of the facility, a facility name that is the name of the facility, and an attached route that indicates the route number of the road to which the facility belongs when the facility is attached to a road such as a junction, interchange, service area, or parking area The number is registered.

FIG. 4 shows the procedure of the facility guidance information presentation process.
As shown in the figure, in this process, based on the current position set in the memory 15 and the map data, it is monitored that the current position becomes a position on the expressway (step 402). If the current position is a position on the expressway, the size and arrangement of the navigation window 300 set on the display screen of the display device 3 via the GUI control unit 13 are as shown in FIG. 6a. While changing to occupy the left half of the display screen of the display device 3, the facility guidance window 600 is set to occupy the right half of the display screen of the display device 3, and the user-specified type acceptance process is started (step 404). The process proceeds to step 406. Here, in the user-specified type acceptance process activated in step 404, as shown in FIG. 6a, a facility guidance window 600 is displayed with a junction (JCT), an interchange (IC), a service area (SA), and a parking area (PA). The user designation type setting button 601 provided for each facility type of the facility associated with each expressway is displayed, and the facility type corresponding to the user designation type setting button 601 operated by the user is displayed. If the facility type is set as the user-specified type, a process of excluding it from the user-specified type is performed. Note that the initial value of the user-specified type is, for example, all facility types of JCT, IC, SA, and PA.

  Next, if the process proceeds to step 406, it is determined whether or not the route is currently being guided based on whether or not a recommended route is set (step 406). From this point, when traveling along the recommended route, a section on the recommended route to the next IC to be used as an expressway exit is set as a guidance target road section (step 408). And among the facilities associated with the expressway located in the guidance target road section, the facility designated by the user and the facility associated with the expressway of the facility type of JCT or IC, and when traveling along the recommended route, The facility associated with the expressway to be used as the expressway exit or the expressway transfer entrance is selected as a guide candidate facility (step 410). Then, the process proceeds to Step 412. Here, among the facilities associated with the expressway located in the guidance target road section, the facility specified by the user is registered with the facility point information indicating the position in the guidance target road section and the same facility type as the user specified classification. It is obtained as a facility corresponding to the facility record. In addition, an expressway-associated facility of a JCT or IC facility type, and when traveling along a recommended route, an expressway-associated facility that is used as an expressway exit or an expressway transfer entrance is JCT or IC Is registered in the facility type, and the point on the recommended route is obtained as the facility corresponding to the facility record registered in the facility point information.

  On the other hand, if the route is not being guided (step 406), the section of the highway where the current position is located is located on the current traveling direction side from the current position is set as the guidance target road section (step 424), and within the guidance target road section Among the facilities associated with the expressway located at, the facility designated by the user is selected as a guidance candidate facility (step 426). Then, the process proceeds to Step 412.

  If the process proceeds to step 412, n guide candidate facilities closer to the current position are selected as guide facilities from the guide candidate facilities, a facility guide image for guiding the guide facilities is created, and a GUI control unit is created. 13 is displayed on the facility information window 600. Details of the facility guidance image will be described later.

  Then, a timer having a predetermined time-out time is set (step 414), whether the user-specified type changes (step 416), whether the timer time-out occurs (step 418), or the current position is a position on the expressway Wait until it disappears (step 420), or if the user-specified type changes (step 416) or if a timer timeout occurs (step 418), the process returns to step 406.

  On the other hand, if the current position is no longer a position on the expressway (step 420), the user-specified type acceptance process is terminated, the facility guidance window 600 is closed, and the size of the navigation window 300 is set to the display screen of the display device 3. The entire size is restored (step 422), and the process returns to step 402.

The facility guidance information presentation process has been described above.
Here, the details of the facility guidance image displayed on the facility guidance window 600 in step 412 of the facility guidance information presentation process described above will be described.
Now, as shown in FIG. 5a, as an expressway associated facility, an expressway 501 accompanied by SA (x1-x4), PA (y1-y6), IC (w1-w5), and JCT (z1-z2), There is a highway 502 associated with PA (y7) and JCT (z2). As shown by the dotted line in the figure, the highway-associated facility is designated as x1-w1-y1-z1-y2-w2-x2-y3- It is assumed that a recommended route that passes in the order of w3-y4-x3-w4-y5-z2-y7 is set. Further, it is assumed that the number n of guidance facilities selected from the guidance candidate facilities in step 412 of the facility guidance information presentation process is 3.

  In this case, when the current position is located at a point 511 before x1, as shown in FIG. 5b, when SA is set as the user-specified type, the control unit 16 performs facility guidance as shown in FIG. 6a.
