  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<System configuration>
First, the system configuration of the route guidance system 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating a system configuration of an example of a route guidance system 1 according to the present embodiment.

  As shown in FIG. 1, the route guidance system 1 according to the present embodiment includes an electronic device 10 and a server device 20, and is communicably connected via a wide area network N such as the Internet.

  The electronic device 10 is, for example, a navigation device (so-called car navigation) mounted on a vehicle or the like. The route guidance system 1 may include a plurality of electronic devices 10.

  A client program 100 is installed in the electronic device 10. In addition, the electronic device 10 includes a map data storage unit 110 and a network data storage unit 120.

  The electronic device 10 requests the server device 20 to search for a route from the current location to the destination by using the client program 100 based on, for example, the destination or waypoint input by the user. In addition, the electronic device 10 searches for a route from the current location to the destination based on, for example, a destination or waypoint input by the user and network data stored in the network data storage unit 120.

  Then, the electronic device 10 displays the route searched by the server device 20 or the route searched by the electronic device 10 on the map indicated by the map data stored in the map data storage unit 110 by the client program 100. To do. Thereby, the electronic apparatus 10 can perform route guidance with respect to the user.

  As described above, the electronic device 10 can request the server device 20 to search for a route, and the electronic device 10 can also perform a route search.

  The map data is data for displaying a map on the electronic device 10, and is classified for each type of display target such as green space, rivers, roads, railways, prefectures, and the like. It is managed by dividing it into a known mesh. The map data classified for each type of display target is displayed by being drawn for each mesh on a layer predetermined for each type according to the scale. Therefore, for example, the client program 100 displays a map on the electronic device 10 by combining and superimposing one or more mesh-like layers each drawn with map data classified for each type of display target. To do.

  The network data is data used for route search and the like. For example, node information indicating various points such as intersections, branch points, places where road attributes change, places where road width changes, and the like. Link information to be connected is included. The node information includes, for example, node number, latitude / longitude, intersection name (kanji and reading), presence / absence of traffic signal, and the like. Further, the link information includes, for example, information such as link length, coordinate point sequence, link cost, node numbers at both ends of the link, road attributes, traveling direction, altitude (altitude), and the like. Therefore, the client program 100 performs a route search using a known algorithm such as the Dijkstra method so that the cost of the link from the current location to the destination is minimized.

  The server device 20 is a computer that performs a route search in response to a request from the electronic device 10. The server device 20 may be realized by one or more computers.

  A server program 200 is installed in the server device 20. In addition, the server device 20 includes a map data storage unit 210 and a network data storage unit 220.

  In response to a request from the electronic device 10, the server device 20 uses the current location or destination included in the request and the network data stored in the network data storage unit 220 according to the request from the electronic device 10. The route search from to the destination is performed. As with the client program 100, the server program 200 performs a route search using a known algorithm such as the Dijkstra method so that the cost of the link from the current location to the destination is minimized.

  Then, the server device 20 returns the searched route to the electronic device 10 by the server program 200. At this time, the server device 20 may return map data corresponding to the searched route among the map data stored in the map data storage unit 210 to the electronic device 10.

  Thus, the server device 20 can perform a route search in response to a request from the electronic device 10.

  Here, as for map data and network data, for example, when a new road is laid or an intersection is laid, the latest map data and network data are distributed by the vendor of the client program 100 and the server program 200, etc. Is equal.

  In the present embodiment, it is assumed that the latest network data is stored in the network data storage unit 220 included in the server device 20. On the other hand, the latest network data is not necessarily stored in the network data storage unit 120 included in the electronic device 10. Note that the user of the electronic device 10 can update the network data and the map data to the latest state using a recording medium such as a CD, DVD, or USB memory distributed from a vendor or the like.

<Outline of processing>
Next, an outline of processing of the route guidance system 1 according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram illustrating an outline of processing of the route guidance system 1 according to the present embodiment.

  S1) First, the electronic device 10 transmits to the server device 20 a route search request including, for example, a destination or waypoint input by the user.

  S2) Next, when receiving a route search request from the electronic device 10, the server device 20 searches for a route to the destination based on the destination, waypoint, and the like included in the route search request.

  S3) Subsequently, the server device 20 returns the searched route to the electronic device 10 as point sequence information.

Here, the point sequence information is information indicating the latitude and longitude on the route searched in S2. That is, when a _i (i = 1, 2,..., N) is information indicating latitude and longitude on the route, the point sequence information is (a ₁ , a ₂ ,..., A _N−1 , a _N ). Note that a _i (i = 1, 2,..., N) may include the height at the longitude and latitude in addition to the latitude and longitude on the route. Further, the height may include not only the distance from the reference plane (the sea surface, the ground, etc.) in the vertical upward direction, but also the distance from the reference plane in the vertical downward direction.

S4) Subsequently, when receiving the point sequence information from the server device 20, the electronic device 10 draws a polyline on the map from the point sequence information, and performs route guidance using the drawn polyline as the route 1000. Here, the polyline is drawn by connecting a _i and a _{i + 1} to each i = 1, 2,..., N−1 by a straight line or a curve.

  Thus, in the route guidance system 1 according to the present embodiment, the route searched by the server device 20 is returned to the electronic device 10 as point sequence information. And in the route guidance system 1 which concerns on this embodiment, a polyline is drawn on a map from point sequence information, and the route guidance which used the said polyline as a route is performed.

  Thereby, in the route guidance system 1 according to the present embodiment, for example, even when the network data stored in the network data storage unit 120 of the electronic device 10 is not the latest, the route searched by the server device 20 The same route can be displayed on the map. In other words, in the route guidance system 1 according to the present embodiment, route guidance can be performed using a route that cannot be searched by the electronic device 10 (for example, a route passing through a recently laid road).

  Therefore, according to the route guidance system 1 according to the present embodiment, the electronic device 10 can provide the user with route guidance based on the optimum route using the latest network data.

<Functional configuration>
Next, the functional configuration of the route guidance system 1 according to the present embodiment will be described with reference to FIG. FIG. 4 is a diagram illustrating a functional configuration of an example of the route guidance system 1 according to the present embodiment.

  As shown in FIG. 4, the electronic apparatus 10 according to the present embodiment includes a communication unit 101, an input reception unit 102, a display control unit 103, a drawing unit 104, and a condition setting unit 105 as main functional units. The route search unit 106 and the route guide unit 107 are provided. Each of these functional units is realized by processing that the client program 100 causes the CPU 17 to execute.

  The communication unit 101 transmits / receives various data to / from the server device 20. For example, the communication unit 101 transmits a route search request including a search condition set by a condition setting unit 105 described later to the server device 20. For example, the communication unit 101 receives point sequence information from the server device 20.

  The input receiving unit 102 receives various inputs from the user. For example, the input receiving unit 102 receives an input of a destination, a waypoint, and the like by the user. Further, for example, the input receiving unit 102 receives an input for starting route guidance by the user.

  The display control unit 103 displays various screens. For example, the display control unit 103 displays a map based on the map data stored in the map data storage unit 110 on the display device 12. For example, the display control unit 103 displays the polyline drawn on the map by the drawing unit 104 described later. In addition to these, the display control unit 103 displays, for example, various types of information (for example, various types of information such as facility information, notes, signs, etc.) on a map, and various screens (for example, destinations and via Display a ground setting screen and various setting screens).

The drawing unit 104 draws a polyline on the map from the point sequence information received from the server device 20. That is, the drawing unit 104 forms a straight line between adjacent points (a _i and a _{i + 1} ) of the point sequence information (a ₁ , a ₂ ,..., A _N−1 , a _N ) received from the server device 20. Or a polyline is drawn by connecting with a curve.

  The condition setting unit 105 sets search conditions including various conditions for performing a route search. That is, the condition setting unit 105 includes, for example, the destination received by the input receiving unit 102, the current location measured by the GPS receiver 19 (that is, the latitude and longitude information indicating the current position of the electronic device 10), and the like. Set search conditions. Then, the condition setting unit 105 uses the communication unit 101 to transmit a route search request including the search condition to the server device 20.

  Note that the search condition may include, for example, the waypoint received by the input receiving unit 102. Further, the search condition may include, for example, whether or not a toll road is passing. Thus, the search conditions include various conditions used for route search from the current location to the destination.

  The route search unit 106 performs a route search based on the search conditions set by the condition setting unit 105 and the network data stored in the network data storage unit 120.

  In the route guidance system 1 according to the present embodiment, as described above, the electronic device 10 transmits a route search request including a search condition to the server device 20. For this reason, the electronic device 10 does not necessarily need to perform a route search by the route search unit 106. However, for example, when the communication state between the electronic device 10 and the server device 20 is poor or when it is desired to immediately perform a route search, the electronic device 10 transmits a route search request to the server device 20, and A route search may be performed by the route search unit 106.

  When the route search unit 106 performs a route search, for example, the following processing may be performed. That is, until the route search result (coordinate point sequence information) is received from the server device 20, the electronic device 10 displays the route searched by the route search unit 106 on the map and performs route guidance. When the electronic device 10 receives the route search result (coordinate point sequence information) from the server device 20, the electronic device 10 updates the display screen and displays the route (coordinate point sequence information) searched by the server device 20 on the map. Route guidance.

  The route guidance unit 107 performs route guidance using the polyline drawn by the drawing unit 104 as a route. The route guidance is to guide the user of the electronic device 10 until the destination is reached according to the route. For example, the current position measured by the GPS receiver 19 is matched on the route. In addition, performing route guidance by characters, route guidance by voice, and the like at specific locations on the route are included. In addition, the route guidance includes, for example, guidance when the current location of the electronic device 10 deviates from the route (guidance for returning to the original route, route re-search, etc.)

  Here, in general, a path is a link between nodes, while a polyline is a line in which points included in point sequence information are connected by straight lines or curves as described above. For this reason, the route guidance unit 107 performs route guidance by regarding a polyline as a route.

  As illustrated in FIG. 4, the server device 20 according to the present embodiment includes a communication unit 201 and a route search unit 202 as main functional units. Each of these functional units is realized by processing that the server program 200 causes the CPU 27 to execute.

  The communication unit 201 transmits / receives various data to / from the electronic device 10. For example, the communication unit 201 receives a route search request from the electronic device 10. Further, for example, the communication unit 201 transmits the point sequence information of the route searched by the route search unit 202 described later to the electronic device 10.

  The route search unit 202 performs a route search based on the search conditions included in the route search request received from the electronic device 10 and the network data stored in the network data storage unit 220. Then, the route search unit 202 transmits the searched route to the electronic device 10 as point sequence information by the communication unit 201.

  Here, for example, the route search unit 202 extracts information on coordinate points (for example, latitude and longitude) necessary for drawing the searched route on the electronic device 10 side, and information on the extracted coordinate points Is point sequence information. The point sequence information only needs to include information necessary for drawing the route searched by the route search unit 202 on the electronic device 10 side.

<Details of processing>
Next, details of processing of the route guidance system 1 according to the present embodiment will be described.

Example 1
First, Example 1 will be described. In the first embodiment, the route searched by the server device 20 is transmitted to the electronic device 10 as point sequence information, and after the polyline is drawn from the point sequence information by the electronic device 10, the polyline is regarded as a route. A case where route guidance is performed will be described.

  Hereinafter, the process (Example 1) for starting route guidance in the route guidance system 1 according to the present embodiment will be described with reference to FIG. FIG. 5 is a sequence diagram (Example 1) of an example of the route guidance start process according to the present embodiment.

  In step S501, the condition setting unit 105 of the electronic device 10 sets a search condition. That is, the condition setting unit 105 sets a search condition including, for example, the destination received by the input receiving unit 102, the current location measured by the GPS receiver 19, and the like. Note that the user can input a destination or the like on a screen (search condition setting screen) displayed by the display control unit 103, for example.

  In step S <b> 502, the condition setting unit 105 of the electronic device 10 transmits a route search request including the search condition set in step S <b> 501 to the server device 20 through the communication unit 101.

  In step S <b> 503, when the route search unit 202 of the server device 20 receives the route search request by the communication unit 201, the route search request 202 includes the search condition included in the route search request and the network data stored in the network data storage unit 220. Based on the route search. That is, the route search unit 202 searches for an optimum route from the current location to the destination based on the current location and the destination included in the search conditions, for example.

  In step S504, the route search unit 202 of the server device 20 transmits the route searched in step S503 to the electronic device 10 as point sequence information by the communication unit 201.

  In step S <b> 505, the drawing unit 104 of the electronic apparatus 10 draws a polyline on the map from the point sequence information received by the communication unit 101.

  That is, first, the display control unit 103 acquires map data corresponding to the point sequence information received by the communication unit 101 from the map data storage unit 110, and displays a map based on the acquired map data. The map data corresponding to the point sequence information is, for example, map data indicating a map in a predetermined range including the latitude and longitude of each point included in the point sequence information.

  Next, the drawing unit 104 draws a polyline on the map displayed by the display control unit 103 by connecting adjacent points in the point sequence information with straight lines or curves.

  Here, the polyline drawn on the map is shown in FIG. FIG. 6 is a diagram illustrating an example of a polyline drawn on a map.

  In the screen G100 shown in FIG. 6, a polyline 2000 from the current location S to the destination D is drawn on the map. Thus, on the display device 12 of the electronic device 10, the polyline 2000 similar to the route searched by the server device 20 based on the search condition set in step S501 is displayed on the map.

  In step S506, the route guide unit 107 of the electronic device 10 performs route guidance using the polyline drawn by the drawing unit 104 as a route. That is, for example, when the guidance start button G101 is pressed by the user on the screen G100 shown in FIG. 6, the route guidance unit 107 performs route guidance using the polyline 2000 as a route. Thereby, the user of the electronic device 10 can go from the current location S to the destination D according to the polyline 2000.

  As described above, in the route guidance system 1 according to the present embodiment, the route searched by the server device 20 is transmitted to the electronic device 10 as point sequence information, and the electronic device 10 draws a polyline from the point sequence information. After that, route guidance is performed by regarding the polyline as a route.

  Therefore, in the route guidance system 1 according to the present embodiment, for example, the network device stored in the network data storage unit 120 of the electronic device 10 does not update the network data or the like by the user of the electronic device 10. Even when the data is old, route guidance based on the latest network data can be performed. Therefore, in the route guidance system 1 according to the present embodiment, appropriate route guidance according to the actual road laying situation can be performed.

(Example 2)
Next, Example 2 will be described. In the first embodiment, the case where the route guidance is performed by regarding the polyline as a route has been described, but in this case, the route matching may not be performed appropriately. That is, since a straight line or a curve connecting points included in the polyline does not have various information included in the link information (for example, altitude (elevation), etc.), the self-position (the current location of the electronic device 10) is on the polyline. If it is off, route matching may not be performed properly.

  For example, suppose that the self-position has shifted from the polyline to the side road. When the altitudes of the side road and the polyline are substantially the same, appropriate route matching can be performed based on the latitude and longitude of each point included in the polyline and the latitude and longitude of the own position. On the other hand, if the altitudes of the side road and the polyline are different from each other by a predetermined level, appropriate route matching cannot be performed.For example, if the self-position is on the side road, Matching may occur.

  Therefore, in the second embodiment, route guidance is performed considering a polyline as a route, and appropriate route matching can be performed using the route searched by the route search unit 106 of the electronic device 10.

  Hereinafter, a process (Example 2) for starting route guidance in the route guidance system 1 according to the present embodiment will be described with reference to FIG. FIG. 7 is a sequence diagram (Example 2) of an example of route guidance start processing according to the present embodiment. Note that the processing in steps S501 to S505 in FIG. 7 is the same as that in the first embodiment, and a description thereof will be omitted.

  In step S701, the route search unit 106 of the electronic device 10 performs a route in the background based on the search condition set by the condition setting unit 105 in step S501 and the network data stored in the network data storage unit 120. Perform a search. Thereby, the route search unit 106 can search for a route that is at least partially identical to the route searched by the route search unit 202 of the server device 20 in step S503. In addition, since a path | route connects between nodes by a link, node information and link information are contained.

  In step S702, the route search unit 106 of the electronic device 10 extracts link information corresponding to the polyline drawn in step S505 from the link information included in the route searched in step S701.

  Here, the link information corresponding to the polyline is the link information including the latitude and longitude of the coordinate point sequence of the link information included in the route searched in step S701 described above.

  In step S703, the route guide unit 107 of the electronic device 10 performs route guidance using the polyline drawn by the drawing unit 104 as a route. At this time, the route guidance unit 107 performs route matching using the link information extracted in step S702 described above.

  Here, a case where route matching is performed using the link information extracted in step S702 will be described with reference to FIG. FIG. 8 is a diagram illustrating an example of route matching using link information.

  As shown in FIG. 8A, it is assumed that there is a polyline 3000 on a road R100 and a self-position P on a road R200 having an altitude difference from the road R100. Note that the self-position P includes information on latitude, longitude, and altitude measured by the GPS receiver 19.

  At this time, the route guidance unit 107 compares the altitude included in the link information corresponding to the polyline 3000 (link information extracted in step S702 above) with the altitude of the self position P, and the self position P is It is determined that the vehicle is on the road R200.

  As a result, as shown in FIG. 8B, the route guidance unit 107 can perform route guidance using the new polyline 4000 as a route by performing reroute (re-search for the route) through the road R200. become able to. The reroute can be performed by the electronic device 10 transmitting a route search request to the server device 20 again.

  As described above, in the route guidance system 1 according to the present embodiment, the electronic device 10 performs route guidance by regarding the polyline as a route, and also provides route guidance based on link information of the route searched in the background. Do. For this reason, in the route guidance system 1 according to the present embodiment, in route guidance considering a polyline as a route, for example, route matching based on the altitude of the self position and the like can be performed. In other words, the route guidance system 1 according to the present embodiment can perform not only planar route matching based on latitude and longitude but also three-dimensional route matching based on altitude.

  In the second embodiment, as an example, the case of performing route matching based on the altitude of link information corresponding to a polyline has been described. However, the present invention is not limited to this. For example, the road attribute and the traveling direction of link information corresponding to a polyline are described. Route matching may be performed based on the above.

  Note that the present invention is not limited to the specifically disclosed embodiments, and various modifications and changes can be made without departing from the scope of the claims.
