(First embodiment)
First, the navigation system according to this embodiment will be described in detail with reference to FIG. Here, FIG. 1 is a system configuration diagram of the navigation system according to this embodiment.

  First, a navigation system generally indicated by reference numeral 1 includes a car navigation terminal (referred to as a mobile terminal) 100 installed in a user's vehicle 170 via a cradle 150 and various information installed in a user's home. A home management terminal 90 that provides various types of information to the home terminal 90 and the mobile terminal 100 via a wired or wireless communication network 80 (hereinafter referred to as a navigation management server), and at least the mobile terminal 100 And a road information providing server 70 that provides road information to the navigation management server 20.

  A mobile terminal 100 according to this embodiment includes a terminal control unit 110 that performs overall control of the mobile terminal 100, a camera unit 111, and a mobile terminal 100 for operating the mobile terminal 100 in a portable thin casing 101. Stores an operation unit 112, a GPS unit 113 using a global positioning system (GPS), a communication unit 114 for connecting to the communication network 80, a thin display unit 120 for displaying various information, and map information. And the storage unit 115. The operation unit 112 includes a touch panel 116 disposed on the front surface of the display unit 130 and a plurality of hard keys 117 provided on the outer surface of the housing 101. In addition, a TV tuner and a DVD playback device can be connected to the mobile terminal 100.

  The mobile terminal 100 can determine its own position information via the GPS unit 113 and display this position on a map displayed on the display unit 130. Therefore, the user carrying the mobile terminal 100 can grasp his / her position on the map displayed on the display unit 130 of the mobile terminal 100. In this embodiment, the terminal control unit 110 searches the map stored in the storage device 115 based on the position information acquired via the GPS unit 113, and displays its own position on the searched map. Although it can be displayed, navigation information can also be acquired from the navigation management server 20 connected via the communication unit 114. That is, the navigation management server 20 includes a navigation management control unit 22 including a route search unit 21, a map information management database 23, a member management database 24, and a storage device 26 that stores a facility search database 25. Accordingly, route information can be provided to the mobile terminal 100 based on a search request for route information from the mobile terminal 100 to the destination.

  The mobile terminal 100 according to this embodiment will be described as a system that requests the navigation management server 20 for a route to a destination, acquires the search route, and performs navigation based on the acquired route. However, it is not limited to this. That is, the terminal control unit 110 of the mobile terminal 100 may be provided with a route search unit (not shown), and navigation may be performed based on the route searched by the route search unit.

  Further, the mobile terminal 100 is connected to various information providing sites 75 via the communication unit 114 to acquire and display various types of information like a normal mobile phone or information terminal device. It can also be displayed on the unit 130.

  On the other hand, the home terminal 90 accesses the navigation management server 20 via the communication network 80, and can make a search request to the destination as in the mobile terminal 100, thereby obtaining route information to the destination. can do. The home terminal 90 of this embodiment can be configured by an extremely general personal computer or mobile terminal. That is, the home terminal 90 includes a control device, a storage device, a display device, an input device, and a communication device (not shown) and is connected to the navigation management server 20. Further, in this home terminal 90, route information to the destination can be stored in the navigation management server 20, and this route information can be downloaded to the mobile terminal 100 and used.

  One of the major features of the navigation system 1 is that it provides the user with destination area candidates 210 adjacent to a plurality of destinations (facility) desired by the user.

  That is, in a conventional navigation system search, a specific destination is extracted from search conditions such as an address, a facility name, and a telephone number. Moreover, if there are items that match the search conditions, a method of displaying a plurality of them and selecting a specific destination is adopted. Alternatively, you can go to the place in one hour and search for a specific facility where you can eat and play delicious food. That is, in the conventional navigation system, the main purpose is to search for one specific facility (location) that matches a plurality of search conditions. Therefore, in this conventional search system, only a large store in which a plurality of facilities desired by the user is concentrated in one place can be searched. For example, it is not possible to search for two facilities that meet the search condition and are installed adjacent to each other across a road.

  Therefore, in the present navigation system 1, the destination area candidate 210 adjacent to the facility desired in a specific range is extracted, displayed on the map, and provided to the user, thereby responding to various needs of the user. To do. Specifically, as shown in FIG. 1, destinations that match the search conditions desired by the user are extracted from the facility search database 25, and the range or designation of these extracted destinations (facility) is set in advance. A destination area candidate 210 included in the range is extracted and displayed as a selection area on the map displayed on the display unit 120.

  For example, the search output screen 200 in FIG. 1 is a destination area in which a place where you can eat delicious food and a place where you can shop are within 3 km, where you can drive from 1 hour to 2 hours east from the start point S. The state which displayed the candidate 210 on the map is shown. According to the search output screen 200, the user can grasp at a glance the destination area candidate 210 that matches the desired search condition.

  The area search can be performed by accessing the navigation management server 20 from the mobile terminal 100 or the home terminal 90 via the communication network 80. The navigation management server 20 provides a search input screen 250 (see FIG. 5) based on the user's access, and from the map information management database 23 to the search conditions based on the search conditions specified on the search input screen 250. A matching facility is extracted, and further, a destination area candidate 210 included in a specific range is extracted from the position information of these facilities, and the extracted destination area candidate 210 is mapped on a map. Is provided to users.

  In this search output screen 200, by selecting a destination area candidate 210, an enlarged search output screen 270 (see FIG. 9) that displays detailed map information of the selected destination area candidate 210 can be displayed. . Then, it is possible to determine the destination from this enlarged search output screen 270, or to return to the original search output screen 200 and display the enlarged search output screen 270 of other destination area candidates 210.

  Another major feature of the navigation system 1 is that a direction search is adopted as a search condition indicating the position of the destination.

  That is, in the prior art, when selecting a destination, a method of narrowing down the destination by the prefecture name or address is adopted. However, for those who drive without being aware of a specific destination, the prefecture names and addresses that are clearly separated are not so important, and the direction (direction) starting from the starting position S such as Tohoku and Izu There are many cases of awareness.

  Therefore, in this embodiment, the search target is four directions from the start position S to the east, west, south, and north. Specifically, the navigation management server 20 virtually calculates a direction dividing line P that divides the east, west, south, and north from the start position S, and designates one designated direction such as “east” designated by the user. A destination (destination area candidate 210) that matches the region 220 is extracted.

  Another important feature of the navigation system 1 is that the search output screen 200 displays the four directions of east, west, south, and north divided by the azimuth dividing line P with the start position S as the center. The extracted destination area candidate 210 is displayed in the designated designated direction area 220. Thereby, the user can see the search result at a glance while grasping his / her search condition by looking at the search output screen 200.

  Another important feature of the navigation system 1 is that a destination area candidate 210 included in a specific area is extracted by combining the designated direction area 220 and the arrival time range.

  That is, when a facility desired by the user is searched using only one designated area 220 in the four directions of east, west, south, and north, the number of facilities is enormous, and the burden on the navigation management server 20 becomes large. Also, the user is concerned about the estimated arrival time to the destination to some extent depending on whether he / she is going on a day trip or staying overnight. In this embodiment, therefore, the extraction range of the destination (destination area candidate 210) is designated by combining the designation direction area 210 and the arrival time range. The search output screen 200 of FIG. 1 shows a state in which five destination area candidates 210 that are designated direction areas 220 of “east” and whose arrival time is 1 to 2 hours are selected. For these destination area candidates 210, an indication of the arrival time is shown in the balloon.

  Next, a method of using the navigation system 1 will be described with reference to the screen transition diagrams of FIGS. Here, FIG. 2 is an operation flowchart of the navigation management control unit. 3 to 11 are screen transition diagrams of the mobile terminal.

  In this navigation system 1, the navigation management server 20 is accessed from the mobile terminal 100 or the home terminal 90 via the communication network 80, and the destination area candidate 210 that matches the search condition desired by the user is obtained. Route information from the candidate 210 to the destination can be acquired. Here, in the navigation management server 20, the navigation management control unit 22 acquires information from the map information management database 23, the member management database 24, and the facility search database 25 stored in the storage device 26, so that the mobile terminal 100 or the home terminal 90. Here, the mobile terminal 100 and the home terminal 9 can store the route information of the destination area candidate 210 extracted in the storage device 26 of the navigation management server 20. The mobile terminal 100 can download the stored route information and use it as its own route information. Here, an operation method on the mobile terminal 100 will be described.

  First, in FIG. 3, when a menu operation (not shown) is performed, the terminal control unit 110 of the mobile terminal 100 displays the menu screen 400 illustrated in FIG. 3 on the display unit 120. This menu screen 400 can be operated with a destination selection button 401, a music selection button 402, a television selection button 403, and a setting selection button 403 that enables various settings. When any one of the four selection buttons is selected via the touch panel 116, the terminal control unit 110 displays a corresponding screen (not shown) on the display unit 120 so that various operations and watching TV and music can be performed. It can be carried out.

  Here, it is assumed that the destination selection button 401 is selected. When the destination selection button 401 is selected, the terminal control unit 110 displays a destination menu screen 410 shown in FIG. This destination menu screen 410 includes a search menu selection unit 411 for setting search conditions such as going to home or searching by address, a pair of scroll keys 412 for scrolling the search menu selection unit 411, a destination A return key 413 for returning to the menu screen 410 is provided. When one selection unit of the search menu selection unit 411 is selected, the terminal control unit 110 displays a corresponding input screen (not shown) on the display unit 120.

  However, when the selection unit 414 of “search with multiple conditions” is selected, the own ID information and the own coordinate information acquired by the GPS unit 113 are transmitted to the navigation management server 20 via the communication unit 114. In this embodiment, the navigation management server 20 is requested to search for “search with a plurality of conditions” with a large search load, and the terminal control unit 110 refers to the map information stored in the storage unit 115 for other searches. Search for. Of course, the navigation management server 20 may be requested for other searches, or all searches may be executed by the mobile terminal 100 itself.

  In FIG. 2, when there is an access from the mobile terminal 100, the navigation management control unit 22 of the navigation management server 20 collates the transmitted ID information with the member management database 24 (step 501) and collates. For example, the search input screen 250 shown in FIG. 5 is transmitted to the mobile terminal 100 and the input operation is accepted (step 503).

  On this search input screen 250, search conditions for area search for searching for a destination by a plurality of conditions can be input. In this embodiment, a direction setting unit 251, an arrival time range setting unit 252, a facility setting unit 254, a facility number setting unit 257, a toll road setting unit 258, an area candidate area radius setting unit 259, a search A search execution key 260 for executing the above and a return key 261 are provided.

  The direction setting unit 251 includes “east”, “west”, “south”, and “north” selection keys that are divided into four by diagonally connecting each corner of a quadrangle. That is, four triangular buttons are combined and arranged so as to form a square. FIG. 4 shows a state where “east” is selected. The arrival time range setting unit 252 is provided with a pair of slide buttons 253 for setting the shortest time and the longest time on the time axis, and by sliding the pair of slide buttons 253 by touch operation, The arrival time range up to can be set. In FIG. 4, a range that can be reached by car in the range of 1.5 hours to 2 hours is set.

  Here, the mobile terminal 100 of this embodiment is set under conditions installed in the vehicle 170 as an initial value. This initial value can be changed on a setting screen (not shown) selected and displayed from the setting selection button 403 on the menu screen 400. Of course, this search input screen 250 may be provided with a setting unit (not shown) for setting transportation means such as “car” and “train”. Further, the home terminal 90 is provided with an input field for the start position S.

  The facility setting unit 254 receives a plurality of facilities by selecting a facility selecting unit 255 that selects the type of facility and a detailed selecting unit 262 for the detailed condition. In this embodiment, the setting can be made from the four types of facilities of “eating”, “playing”, “shopping”, and “staying”. That is, when the facility selection unit 255 is selected (check mark), the detailed condition can be set by the operation of the detail selection unit 262. When the detail selection unit 256 is operated, the detail setting screen 280 of FIG. 6 is displayed.

  On this detailed setting screen 280, for example, the type of store such as “Italian” or “Family” can be selected from the facility detail selection unit 281 as the facility to eat. The facility detail selection unit 281 can be scrolled by operating a pair of scroll keys 282, the facility details can be set by performing a determination operation with the OK key 283, and detailed information can be set with the return key 284. It is possible to return to the search input screen 250 without doing so. A plurality of detailed setting screens 280 are set corresponding to the type of facility.

  When the OK key 283 is operated, the screen returns to the original search input screen 250 and the setting content is displayed on the selection confirmation display unit 256. The facility set by the facility setting unit 254 is searched by the OR condition. Therefore, in FIG. 4, “Ramen shop” and “Furniture shop” are search conditions, and therefore, the respective facilities are searched.

  The facility number setting unit 257 is an input field for setting the number of facilities included in the destination area candidate 210 set by the area radius setting unit 259. In this embodiment, the density of the number of facilities included in the destination area candidate 210 set by the area radius setting unit 259 is searched. In the setting of FIG. 5, the search condition is that there are 10 or more “ramen shops” or “furniture shops” in the destination area candidate 210 having a radius of 3 km. The area radius setting unit 259 of this embodiment can select any one of “small (1 km)”, “medium (3 km)”, and “large (5 km)”.

  The toll road setting unit 258 can use a toll road or set a toll range when used as a search condition.

  In this embodiment, the screen management of the search input screen 250 and the search output screen 200 is performed by the navigation management control unit 22 mediated by the terminal control unit 110 of the mobile terminal 100. Therefore, the user operates the search management key 20 by inputting the desired search condition on the search input screen 250 displayed on the display unit 120 of the mobile terminal 100 and operating the search execution key 260. Can be directed.

Returning to FIG. 2, the navigation management control unit 22 receives the search condition specified on the search input screen 250 (step 505), refers to the facility search database 25, and executes an area search (step 507). In this area search, the following search is executed.
(1) From the own vehicle position (start position S) acquired from the mobile terminal 100, the direction dividing line P to be divided into the east, west, south, and north is virtually calculated from the start position S as a base point, and is set by the direction setting unit 251 The coordinate information included in the designated direction area 220 is calculated.
(2) Based on whether or not the toll road setting unit 258 is selected, a target area that can be reached within the time set by the arrival time range setting unit 252 and included in the designated direction area 220 is calculated.
(3) The facility selected by the facility setting unit 254 is extracted within the target area.
(4) The facility extracted in the target area extracts an area having the number of facilities set by the facility number setting unit 257 within an area having a size set by the area radius setting unit 259.

  Then, the navigation management control unit 22 determines whether or not there is a destination area candidate 210 that matches the search condition (step 509). If the destination area candidate 210 is extracted, the navigation management control unit 22 determines the facilities included in the extracted destination area candidate 210. A center position is calculated, a circular destination area candidate 210 having a size set by the area radius setting unit 259 around the center position is calculated, and a route to the extracted destination area candidate 210 is calculated. (Step 511). Then, a map having a size including the target area centered on the start position S is acquired from the map information management database 23, and a search output screen 200 shown in FIG. 7 is generated (step 513).

  In the search output screen 200 shown in FIG. 7, a start position S is set at the center of the screen, an orientation dividing line P is set around the start position S, and the map is divided into four directions, east, west, south, and north. Then, the designated direction area 220 designated by the user is displayed in an identifiable manner, and the extracted area candidate 210 and its route information are displayed in the designated direction area 220. On the search output screen 200, the magnet 201 is displayed so that the upper part of the screen shows “north”. In addition, a search condition confirmation unit 203 for search conditions set on the search input screen 250 is provided at the bottom of the screen.

  Returning to FIG. 2, if the destination area candidate 210 cannot be extracted by the area search in step 509, the navigation management control unit 22 does not display the destination area candidate 210 and its route information. The search output screen 200a shown in FIG. 8 in which the guidance “not done” is written is generated and output to the mobile terminal 100 (step 531). The search output screen 200a can be returned to the original search input screen 250 by operating the redo button 202 (step 533).

  When the destination area candidate 210 is extracted by the route search, the navigation management control unit 22 determines whether the destination area candidate 210 is selected (step 515) and whether the redo button 202 is operated (step 515). Step 523) is monitored.

  When the destination area candidate 210 is selected, an enlarged search output screen 270 for the selected destination area candidate 210 shown in FIG. 9 is generated and output to the mobile terminal 100 (step 517). In the enlarged search output screen 270, the selected destination area candidate 210 is enlarged and displayed on the full display screen. In the enlarged destination area candidate 210, the extracted facilities are displayed according to the coordinates. The enlarged search output screen 270 includes a transit point setting button 271 that uses the destination area candidate 210 as a transit point, a destination setting button 272 that serves as a destination, and a button for returning to the original search output screen 200. 273 is provided. When the waypoint setting button 271 is set (step 519), the navigation management control unit 22 stores the destination area candidate 210 as a waypoint in the storage device 26 (step 535) and the original destination area candidate. The search output screen 200 reflecting the waypoint 210 is displayed again (step 537), and the process proceeds to step 515.

  When the destination setting button 272 is set (step 521), a search output screen 200b shown in FIG. 10 on which only the destination area candidate 210 set as the destination is displayed is displayed (step 539). The search output screen 200b includes a start button 230 for starting navigation, a registration button 231 for storing the search output screen 200b in the storage device 26 and using it for later download, and the original search output screen 200. A return redo button 232 is provided.

  When the storing operation is accepted (step 541), a setting screen (not shown) for storing is displayed (step 542), and the process is terminated (step 547). When a start operation is accepted (step 543), navigation to the destination area candidate 210 is started (step 544). Further, when a return operation is accepted, the process proceeds to step 505.

  In this embodiment, on the search output screen 200, the setting content of the direction setting unit 25 can be changed. This will be described with reference to FIG. The navigation management control unit 22 monitors whether or not a touch operation has been performed on the direction dividing line P. Then, when the direction division line P is touched, one of the direction division lines P extended outward from the start position S is activated and rotated around the start position S according to the drag operation. Let

For example, the search output screen 200 of FIG. 11 shows a state in which the designated direction area 220 of only “east” that has been set so far is expanded to “south” by the above operation. When the designated direction area 220 is expanded, the navigation management control unit 22 virtually calculates the changed azimuth dividing line P based on the start position S, and the coordinates included in the expanded designated direction area 220 Information is calculated, and the area search is searched again based on the calculation result. FIG. 11 shows a state where one destination area candidate 210 has been added as a result of this extended search.
(Second embodiment)
Next, a second embodiment of the navigation system according to the present invention will be described with reference to FIGS. 12 and 13. Here, FIG. 11 is a search input screen diagram. FIG. 12 is a search output screen view. Here, the description of the same parts as those in the first embodiment is omitted.

  In FIG. 12, the system of the second embodiment is characterized in that a search by vehicle (car) and a search by train and foot can be selected by a selection operation of the flag selection unit 266. That is, the search input screen 265 according to this embodiment is provided with two sheets of “car” that is the same as the input content of the search input screen 250 described in FIG. 5 and “train + walk” that is substantially the same. The selection of the sheet can be set by a selection operation of the flag selection unit 266. When one of the two sheets is selected, the navigation management control unit 22 performs a search using the selected means. In this embodiment, a train fee input unit 267 is provided instead of the toll road setting unit 258.

  FIG. 13 shows a search output screen 240 according to the second embodiment. The search output screen 240 has an output format similar to that shown in FIG. Here, the search result of “train + walk” is shown. As can be seen from the figure, in this area search, two destination area candidates 210 are extracted, and a route using a train from the start S to the destination area candidate 210 regarding these two places is displayed. In the case of “train + walk”, since there is a relationship between the train ride time and the walk time, the destination area candidate 210 set by the area radius setting unit 259 is regarded as the maximum size. When this method is used, for example, in the case of a nearby station a, it may become a donut-shaped destination area candidate 210 in relation to walking time. In the case of a distant station b, since the walking time is reduced, the size of the destination area candidate 210 is also small.

  As described above, the navigation management server (navigation management server) according to this embodiment includes a navigation management control unit including a route search unit, a map information management database, a member management database, and a storage device that stores a facility search database. A search input screen for accepting access based on an authentication number and a coordinate position of a start point from a mobile terminal established on the Internet and connected via a communication line, and inputting search conditions for a plurality of destinations Output to a mobile terminal, accept an area search with the search condition input on the search input screen, and extract a destination area candidate where a plurality of facilities that match the search condition are adjacent to a specific area, the extraction A search output image in which the destination area candidate is mapped on the map along with route information to the destination area candidate. It generates and the generated search output screen adopts the information providing method for outputting to the mobile terminal.

  In this case, the search condition includes a direction setting unit that targets one of the four directions of east, west, south, and north centering on the start position, and when the navigation management server receives the search condition, the start position is determined. It is more effective to virtually calculate a direction dividing line that divides the east, west, south, and north at the base point and extract a destination that matches one designated area set by the search condition.

  In addition, it is more effective to display the four directions of east, west, south, and north divided by the direction dividing line around the start position on the search output screen, and display the extracted destination area candidates in the designated designated area. .

  Further, the search condition includes an arrival time range to the facility, and the navigation management server combines the arrival time range and the designated direction area to select destination area candidates included in a specific area. Extraction is more effective.

  Further, it is more effective to change the range of the designated direction area by rotating the azimuth dividing line from the start position on the search output screen.

  In addition, it is more effective if the search condition includes a transportation means for identifying a vehicle and a train, and the navigation management server extracts a destination area candidate based on the transportation means.
