The route search is performed again as a stopover, and the itinerary table in which the searched route is divided into multiple sections according to road type and main facilities, and the genre list of candidate facilities set as stopovers in each section are output. Facilities selected by the user among facilities searched for by peripheral search or output to the device 6, or certain conditions such as the closest distance from the route, or the shortest time The route search means is controlled so that the route search is performed within the section designated as a waypoint as a facility that is prioritized under conditions such as reachable in the area, and it is necessary for navigator processing means for map display processing, route search processing, route guidance Central processing unit 4 for performing simple display / voice guidance processing and further controlling the entire system, communication device 5 for transmitting / receiving traffic information, detecting information on the current position of the vehicle and transmitting / receiving location information, and outputting information on route guidance The output device 6 includes a display for displaying route information and voice guidance, a speaker, and the like.

FIG. 2 is a diagram showing an example of a guidance screen that simultaneously displays an itinerary table obtained by dividing a search route into a plurality of sections in a main facility and a genre list that may be set as a waypoint.
When a route to the starting point S and destination G is searched, the route is divided into four sections at several major facilities on the route, in this example, the Okazaki Interchange (IC), ○ △ Junction (JCT), and Tokyo IC. and divided itinerary, as a genre that might be set as a transit point along the route, CVS (convenience stores), GS (gas station), SA (service area), PA (parking area), coffee shop, Meals, bookstores, souvenirs, etc. are listed at the same time. The genre that may be set as a waypoint varies depending on the type of road that constitutes the route. For example, it is not displayed because there are few SA, PA, etc. on general roads. For example, supermarkets, drug stores, ramen shops, Italian cuisine Stores are displayed as a list, and SA, PA, IC, JCT, etc. are displayed on toll roads such as expressways. Further, as the genre to be displayed, an arbitrary group created by the user may be displayed in addition to the existing genre, and the genre may be determined from a past destination or a waypoint setting history.

The guidance screen has a touch panel, and each section of the itinerary is a search designation section that designates a transit point, for example, touches CVS as a genre and is dragged as indicated by a broken line and released in a search designation section a, or When CVS and search specified section a are touched, it is recognized that search specified section a and CVS are specified. When the search designation section a and the genre CVS are recognized in this way, the facility corresponding to the genre CVS designated within the search designation section a is searched for in the vicinity. In this example, the search designation section a is a section of a general road. For example, the CVS is searched around under conditions such as within a predetermined distance from the route or within a predetermined range from a point on the route. Here, when a plurality of CVSs are searched, CVS selected by the user among them, or certain conditions set in advance, for example, CVS of a predetermined store series, CVS at the shortest distance from the route, etc. The route is searched again using the priority CVS as a transit point. For example, the route is searched again in the search designated section a and guided.

  Touching the genre SA and dragging as indicated by a broken line to release it in the search designated section c, or touching the SA and the search designated section c, it is recognized that the search designated section c and SA are designated, and the search designation is made. The SA is searched around in the interval c. Since the designated search section c is a toll road section, the area around the SA is searched within a range that can be reached without departing from the toll road area. When a plurality of SAs are searched, the route is re-searched using the SA selected by the user or a certain preset condition, for example, the SA given priority under the conditions such as the largest area, as a waypoint. For example, the route is re-searched and guided within the search designated section c.

  Touching the genre “souvenir” and dragging as indicated by a broken line to release it in the search designated section d, or touching the “souvenir” and the search designated section d, it is recognized that the search designated section d and “souvenir” are designated. Then, a search for “souvenir” shops is performed in the search designated section d. The search designated section d is a section of a general road. For example, a search for a “souvenir” shop is performed in the vicinity within a predetermined distance from the route or within a predetermined range from a point on the route. Here, when a plurality of “souvenir” stores are searched, the “souvenir” given priority in the conditions of the store selected by the user or a predetermined condition such as a store handling a specific souvenir. The route is re-searched using the store as a transit point. For example, the route is re-searched and guided in the search designated section d.

FIG. 3 is a diagram showing an example of further subdividing each section of the itinerary table.
Here, the search designated section a of the departure place S and the Okazaki IC in FIG. 2 is divided into three sections, which are divided into three sections, with a1 near the current location, a3 near the IC, and a2 near the current location / other than the IC. The division method is arbitrary, such as equal division, division at major facilities, and the number of divisions may be arbitrarily set according to the length of the section. With these divided sections a1, a2, and a3 newly designated as search specified sections, the section search and genre specification are performed in the same way as in FIG. A re-search is performed, and for example, a route search is performed within the search designated section a or the divided sections a1, a2, or a3 that can be searched for guidance.

FIG. 4 is a diagram for explaining a search method when a corresponding facility is not found in a specified section.
Here, a case will be described in which each search designation section on the route illustrated in FIG. 2 is divided into three sections illustrated in FIG. Assume that the search designated section a of the general road from the departure place S to Okazaki IC is divided into a section A, a section B, and a section C. First, when the CVS is designated with the route section C as the search area, the CVS is searched in the vicinity within the section C, as described with reference to FIG. When the CVS facility is not searched in the search for the section C, the adjacent section B which is the route section of the same general road is searched as the next search area, and when the CVS facility is not searched in the search area B, the same general The adjacent section A which is the route section of the road is searched. Even if they are adjacent to each other, the search area D is a different section with a different road type, so it is not included in the search area. If the CVS facility is not searched in the search area A, the facility is not found, or a facility similar to the CVS, such as a supermarket or a miscellaneous item, is searched in the order of the search area C → B → A, for example. You may do it. When the corresponding facility is searched, the facility is set as a transit point.

  Next, it is assumed that the search designation section b of the toll road from Okazaki IC illustrated in FIG. 2 to △ JCT is divided into three sections D, E, and F. When the SA is designated with the route section F as a search area, the SA is searched in the vicinity of the section F. If the SA is not searched in the search for the section F, the adjacent section E that is the route section of the same toll road is searched as the next search area, and if the SA is not searched in the search area E, the route section of the same toll road Is searched for an adjacent section D. If the SA is not searched even in the search area D, the surrounding search is sequentially performed using the sections G, H, and I divided by the Tokyo IC from the adjacent toll road section △ JCT as a search area, and set as a transit point. . Thus, when a facility cannot be searched in one search specified section, if the road type is the same, the search range is expanded to an adjacent search specified section and the search is performed.
