Description

  The present invention relates to a stop spot determination system for deciding where to stop when stopping at a restaurant or the like when traveling on a trip by dividing a plurality of vehicles, and a terminal device and server device used therefor is there. In the present invention, the stop spot determination system as described above, and the terminal device and server used therefor, in particular, search for a stop spot candidate using a navigation function or facility search function in one vehicle, It is distributed to the vehicle, and the stop spot can be determined by voting.

  2. Description of the Related Art Conventionally, an in-vehicle navigation device that provides an automobile driver with an optimal route from a departure place to a destination has been provided. A conventional navigation device is a map data storage device such as a CD-ROM or an IC card in which map data is recorded, a display device, a gyro, a GPS (Global Positioning System), a vehicle speed sensor, and other current positions and directions of vehicles. It has a vehicle movement detection device to detect, reads out map data including the current position of the vehicle from the map data storage device, and draws a map image around the vehicle position on the display device based on the map data. In addition, the vehicle position mark (location) is displayed superimposed on the map image on the display screen, the map image is scrolled according to the movement of the vehicle, the map image is fixed on the screen, and the vehicle position mark is moved. This allows you to see at a glance where the vehicle is currently driving.

  Usually, such a vehicle-mounted navigation device is equipped with a route guidance function that allows a driver to easily travel to a desired destination without making a mistake on the road. According to this route guidance function, the route with the lowest cost connecting from the starting point to the destination is searched using map data by performing a simulation calculation such as Dijkstra method, and the searched route is stored as a guide route. While traveling, the guide route is drawn thickly on the map image with a different color from other roads and displayed on the screen, or the vehicle approaches within a certain distance to the intersection where the route on the guide route should be changed Sometimes, the driver can easily grasp the optimum route to the destination by drawing an arrow indicating the route at the intersection where the route should be changed on the map image and displaying it on the screen.

  The in-vehicle navigation device is a stand-alone navigation device having a route search function and map data, but such a navigation device needs to have all the functions necessary for navigation, and the device is large. The price was high. Due to recent developments in communication and information processing technologies, so-called communication-type navigation systems that add communication functions via a network to vehicle-mounted navigation devices and communicate with a route search server to acquire guide route data and map data have become widespread. Have been doing. Furthermore, a system using a mobile phone as a navigation terminal has been put into practical use as a navigation system for pedestrians.

  A general navigation device, a route search device and a route search method used in a communication navigation system are disclosed in, for example, the following Patent Document 1 (Japanese Patent Laid-Open No. 2001-165681). This navigation system is configured to send information on a departure point and a destination from a portable navigation terminal to an information distribution server, and the information distribution server searches and guides a route that matches a search condition from road network and traffic network data. Has been. As the search condition, there are means for moving from the departure place to the destination, for example, walking, automobile, combined use of railroad and walking, and the route is searched as one of the search conditions.

  The information distribution server has roads (routes) of map data as nodes and nodes as the positions of inflection points, links connecting the nodes as links, and cost information (distance and required time) of all links as a database. ing. Then, the information distribution server sequentially searches for a link from the departure node to the destination node with reference to the database, and traces the node and link with the smallest cost information of the link as a guide route. The shortest route can be guided to the portable navigation terminal. As such a route search method, a method called label determination method or Dijkstra method is used. Patent Document 1 also discloses a route search method using this Dijkstra method.

  In addition, services by servers that provide various information to terminal devices accessed via a network are expanding, searching for stores and other places of interest (POI: Point of Interest), railways, etc. It is also possible to search for transportation routes, timetables, desired route sections, and required times. A system is also realized in which a route search server that provides a navigation service can also provide these search services.

  In providing information on stores and events, a user operates a mobile terminal to input a store or event category and an area to be searched for a search request. The server searches for stores and events that fall into the specified category and exist in the area, and the information is distributed to the mobile terminal device. In providing the timetable, when the user operates the mobile terminal to designate a route, the timetable of the route is presented on the screen of the display device of the mobile terminal. Further, in the transfer guidance, the recommended route is presented by the user specifying the departure place and the destination.

  Various services such as those described above may be used when traveling with a vehicle-mounted navigation system or communication-type navigation terminal device carried in a vehicle. In addition, a group may divide a plurality of vehicles and go on a trip. In this case, it is preferable that various information acquired by the navigation terminal device can be shared.

  However, when a group divides a plurality of vehicles and travels, the departure places are different, and all the vehicles are not necessarily close to each other. Under such circumstances, when it is necessary to stop at a restaurant on the way to the destination, in order to decide where to stop, it has traditionally been decided in advance where to stop or a specific place in front. For example, after meeting in the service area, parking area, etc., it was decided by consultation or by contacting with a mobile phone or the like.

  For example, the following Patent Document 2 (Japanese Patent Laid-Open No. 2003-109185) discloses an invention of an in-vehicle information communication device. In this invention, an in-vehicle information communication apparatus that exchanges information such as a current position and a destination by using e-mail between vehicles is proposed. By using such an apparatus, it is possible to determine where to stop by exchanging information while the vehicle is moving.

In the following embodiments, the description will be made as a navigation device.

  The navigation apparatus 1 shown in FIG. 1 is generally controlled by a controller 2. The controller 2 includes a CPU 3, a ROM 4 that stores a program for operating the CPU 3, and a RAM 5 that provides a work area for the CPU 3.

  The controller 2 reads road map information in a predetermined range from the CD-ROM via the CD drive 12 and the memory control unit 6, and causes the display control unit 9 to display the road map on the display 13. Further, the vehicle position detection unit 7 detects the current position of the vehicle based on data from the GPS receiver 15, the vehicle speed sensor 16, the direction sensor 17, and the like, and the controller 2 displays it on the display 13. The current position of the vehicle is displayed on the map.

  In addition, the controller 2 is connected to a mobile phone connection unit 11 and can communicate with a navigation device mounted on another vehicle via a mobile phone 19 set therein. Communication with a navigation device mounted on another vehicle can be performed using, for example, an electronic mail function of the Internet.

  Further, the controller 2 has route search means for receiving the position data of the destination input from the input device 14 via the input control unit 10 and calculating the optimum route from the current position to the destination. Thereby, the searched route is displayed on the map of the display 13. Furthermore, it has a guidance means for outputting a voice signal to the speaker 18 via the voice control unit 8 and performing voice guidance of the route while driving the vehicle.

  The navigation device 1 operates as either a distribution source terminal or a distribution target terminal, and the controller 2 has the following functions. That is, the controller 2 receives a search condition input from the input device 14 via the input control unit 10 and receives a POI on the map, that is, a place of interest to the user (such as various shops and facilities) ) For searching for POI.

In addition, the controller 2 includes a list distribution unit that distributes the POI list searched by the POI search unit to the distribution target terminal, a totaling unit that totals selection information received from the distribution target terminal and determines a stop spot, And a totaling result distribution unit that distributes the result totaled by the totaling unit to the distribution target terminal.
Further, the controller 2 displays a POI list distributed from the distribution source terminal and accepts POI selection, and a selection to return the POI selected by the POI selection unit as selection information to the distribution source terminal And an information return means.

  Such a navigation device is mounted on each vehicle, and the navigation device mounted on one of the vehicles functions as a distribution source terminal described later, and the navigation devices mounted on other vehicles are covered. Functions as a distribution terminal. Which vehicle's navigation device is used as the distribution source terminal may be determined as appropriate, such as the vehicle on which the secretary rides, the vehicle running at the top, and the like.

  Next, with reference to a flowchart, operation | movement of the navigation apparatus which is a delivery origin terminal, and the navigation apparatus which is a to-be-delivered terminal is demonstrated. FIG. 2 is a flowchart showing processing from POI search to distribution processing in the distribution source terminal.

  When an operation for entering the POI search mode is performed from the input device 14, this process starts, and first, a search screen is displayed on the display 13 (step S1). On the screen, a button for selecting a POI category such as a restaurant, a coffee shop, a convenience store, and a button for selecting whether to search in the vicinity of the current area or in a place on the route to the destination are displayed. .

  On the screen, it is determined whether or not the category selection button has been pressed (step S2). If the category selection button has been pressed, it is determined whether or not the area selection button has been pressed (step S3). When the area selection button is pressed, the search for the corresponding POI is started (step S4). When the search is completed, the search result is displayed on the display 13 (step S5), and the search is performed on all the delivery target terminals. The POIs that have been processed are distributed as a list (step S6).

  Each terminal to be delivered that has received the POI list performs the following processing. FIG. 3 is a flowchart showing the POI selection process in the terminal that has received the list distribution. A POI list is received from the distribution source terminal (step S7), and the fact that the list has been received is displayed on the display 13 (step S8). Looking at the display, the user on the vehicle operates the display button to display the distributed list, but the distributed terminal determines whether or not the display button has been operated (step S9). ) If the display button is operated, the list is displayed on the display 13 (step S10).

  The user sees the list and selects the POI that he (or themselves) wants to visit. The terminal to be delivered determines whether or not the POI is selected (step S11). If selected, the selected POI is returned to the distribution source terminal (step S12).

  On the other hand, after the POI list is distributed to each terminal to be distributed, POI selection processing is also performed at the distribution source terminal. FIG. 4 is a flowchart showing POI selection processing in the distribution source terminal. After the POI list is distributed to each terminal to be distributed, first, the same POI list as that distributed is displayed on the display 13 (step S13).

  The user looks at the list and selects the POI that he (or himself) wants to visit, but the distribution source terminal determines whether or not the POI is selected (step S14). If selected, the selected POI is held (step S15).

  Thereafter, the distribution source terminal executes a counting process. FIG. 5 is a flowchart showing the counting process in the distribution source terminal. First, the selected POI flag indicating the number of votes of POI selected by the user and held in step S15 is set to 1, and then the selection result from each delivery target terminal is received (step S16), and the flag of the selected POI is set to 1. Is added (step S17).

  It is determined whether or not the selection result has been received from all of the terminals to be distributed (step S18). If there is a terminal that has not been received yet, the process returns to step S16 and continues to be received. Is completed (step S19), the result of the aggregation is displayed on the display 13 (step S20). Then, the distribution result and the determined POI are distributed to each terminal to be distributed together with the position information (step S21).

  When the counting result is obtained in this way and the POI to be visited is determined, the distribution source terminal and each distribution target terminal re-search for the optimum route to the destination via the POI and perform the route change process. . FIG. 6 is a flowchart showing route change processing in the distribution source terminal.

  The user first operates the display button to display the total result, but the distribution source terminal determines whether or not the display button has been operated (step S22), and when the display button is operated, the total result is displayed. This is displayed on the display 13 (step S23). The display screen includes a display for confirming whether or not the POI is set as a passing point, and the distribution source terminal determines whether or not there is an input for confirming that the POI is set as a passing point (step S24). If confirmed, the route change process is executed using the determined POI position information (step S25), and the changed route is displayed on the display 13 (step S26).

  FIG. 7 is a flowchart showing the route change process in the terminal that receives the distribution of the total results. The count result is received from the distribution source terminal (step S27), and the fact that the count result has been received is displayed on the display 13 (step S28). Looking at the display, the user on the vehicle operates the display button to display the distributed total result, but the terminal to be distributed determines whether or not the display button has been operated (step) S29) If the display button is operated, the total result is displayed on the display 13 (step S30).

  The display screen includes a display for confirming whether or not the POI is set as a passing point, and the distribution target terminal determines whether or not there is an input for confirming that the POI is set as a passing point (step S31). If confirmed, the route change process is executed using the position information of the delivered POI (step S32), and the result of the route change is displayed on the display 13 (step S33).

  Next, a route search method will be described. The road network data for route search is configured as follows. For example, when the road is composed of roads A, B, and C as shown in FIG. 8, the end points, intersections, and bending points of the roads A, B, and C are used as nodes, and the roads connecting the nodes are directed links. Link cost data with node data (node latitude / longitude), link data (link number) and link cost of each link (link distance or time required to travel the link) as data Composed.

  That is, in FIG. 8, Nn (◯ mark) and Nm (◎ mark) indicate nodes, and Nm (◎ mark) indicates a road intersection. Directional links connecting the nodes are indicated by arrow lines (solid line, dotted line, two-dot chain line). As for the links, there are links facing in the upward and downward directions of the road, but in FIG. 8, only the links in the direction of the arrows are shown for the sake of simplicity.

  When route search is performed using such road network data as a route search database, links linked from the starting node to the destination node are traced to accumulate the link cost, thereby minimizing the accumulated link cost. Search and guide the route. That is, in FIG. 8, when a route search is performed with the departure point as the node AX and the destination as the node CY, the road travels from the node AX to the road A, turns right at the second intersection, enters the road C, and reaches the node CY. The link cost is accumulated sequentially, and a route that minimizes the accumulated link cost is searched for and guided.

  Although other routes from the node AX to the node CY are not shown in FIG. 8, there are actually other such routes, so that a plurality of routes that can be reached from the node AX to the node CY are displayed. A search is performed in the same manner, and a route with the lowest link cost is determined as the optimum route. This method is performed by, for example, a known method called the Dijkstra method.

  In the first embodiment, the navigation device 1 is a stand-alone type device, and the communication function is described as having a configuration using a mobile phone connected to the navigation device 1, but the present invention is not limited to this. For example, the navigation device 1 may be a terminal device in a communication navigation system. In this case, since the terminal device has a communication function, communication can be performed without using a mobile phone.

  In the first embodiment, each vehicle has the configuration in which the navigation device 1 is mounted on the vehicle. However, one vehicle has the navigation device 1 mounted on the vehicle, and the other vehicle is on the passenger seat. It is also possible to employ a configuration using a mobile phone possessed by a person. In this case, distribution from the navigation device 1 is received by the mobile phone, and data transmission to the navigation device 1 is performed from the mobile phone. In this case, the mobile phone preferably has a map display function. A current mobile phone has a function of downloading and displaying map data using data communication, and can be used as a terminal device of the present invention.

  As described above, in the first embodiment described above, a plurality of vehicles heading to the same destination have been described as one group. For example, a terminal receiving a specific spot search service in the same area exists in the same area. An unspecified number of terminals may be grouped to deliver a POI list, and recommended spots may be voted out of them, and the results may be aggregated to determine a stop-off spot. Further, for reference, the counting result of voting may be distributed to the terminal that has voted.

  However, in the case of this Example 2, since it will be delivered to an unspecified number of partners, and there is not always a reply for voting from the delivery destination, a vote is accepted with a fixed time limit, It needs to be tabulated. Further, in the case of such a system, it is necessary to grasp terminals existing in the same area, and it is preferable that the system has a configuration using a communication type navigation device centering on a server.

  FIG. 9 is a system configuration diagram showing the configuration of the stop spot determination system according to Embodiment 2 of the present invention. As shown in FIG. 9, the stop spot determination system includes a terminal device 20 and a route search server 30 connected via a network NW. This drop-in spot determination system includes a POI information distribution server 50 that provides detailed information such as the location and service contents of POIs belonging to various categories, and various information distribution servers 51 that provide content and other information such as music and various images. It is configured with.

  The route search server 30 can acquire necessary data from the POI information distribution server 50 or another information distribution server 51 via the network NW and add it to its own database. Similarly, a search request can be transmitted to the POI information distribution server 50 or another information distribution server 51 to obtain a desired search result.

  The route search server 30 is not limited to the above configuration, and may have a map distribution server that distributes a map of a POI location and a POI search server function together with a navigation service function. The terminal device 20 can also use a mobile phone, and may be a portable device such as a PDA, a music player, a portable game machine, or a personal computer (PC).

  The route search server 30 shown in FIG. 9 includes a map database 34 that stores vector map data including POI data, and a route search network database 35. When a route search request is received from the terminal device 20, the search network database 35 is stored. Route search with reference. And it has the general navigation function which transmits the guidance route (recommended route) obtained from the result of route search to the terminal device 20. Further, when there is a search request specifying a point on the guidance route or a POI category from the terminal device 20, the peripheral search of the point is performed to search for a candidate POI and distribute map data and POI data to the terminal device 20. .

  On the other hand, the terminal device 20 basically has the same configuration as the navigation device 1 described in the first embodiment, but the terminal device 20 in the second embodiment is a communication-type navigation terminal, and the navigation device in FIG. 1, it is not necessary to include the mobile phone connection unit 11, the vehicle speed sensor 16, the direction sensor 17, and the CD drive 12. Positioning of the current position is performed by a GPS receiver.

  The route search server 30 includes a map database (not shown), and stores map data composed of unit map data divided by a predetermined latitude / longitude range as shown in FIG. That is, as shown in FIG. 10, the map data is divided into areas in units of predetermined latitude and longitude, and is configured as mesh unit map data M11 to M33. When distributed to the terminal device 20, the unit map data M21, M23, M12, and M32 adjacent to the unit map data M22 including the current position PP of the terminal device 20 in the vertical direction, the horizontal direction, and the diagonal direction are centered. , M11, M13, M31, and M33, a total of nine unit maps are distributed.

  When the terminal device 20 moves and the map data is insufficient, the moving direction of the terminal device 20 is determined, and the route search server 30 distributes the insufficient unit map data. The same applies when the terminal device 20 makes a distribution request for map data by designating a specific point or POI (Point of Interest) position. The guide route data and POI data are distributed to the terminal device 20 together with the vector map data. The terminal device 20 receives map data, guide route data, and the like from the route search server 30, and displays the map and the guide route on the display means.

  The route search server 30 provides the following services in units of areas delimited by a predetermined fixed latitude and longitude range. That is, the candidate POI data distributed to the terminal device 20 receiving a specific spot search service in each area is stored in the storage means, and the candidate POI data is stored in an unspecified number of terminal devices 20 existing in the area. Distribute (POI list).

  The terminal device 20 that has received the distribution of the POI list can vote for recommended spots from the POI list, and the voting results are totaled by the route search server 30. In addition, each terminal device 20 can make a distribution request for the total result. Therefore, the user of the terminal device 20 can select a stop spot by referring to the vote result (recommended spot) of the POI list searched by an unspecified number of terminal devices existing in the same area.

  However, in the case of the second embodiment, the distribution is made to an unspecified number of partners, and there is not always a reply for voting from the distribution destination. Therefore, the route search server 30 sets a predetermined time limit. It is necessary to accept and vote and to count.

  In the case of the second embodiment, it is necessary for the route search server 30 to grasp the terminal device 20 existing in each area, accumulate candidate POI data, distribute the POI list, and total the voting results. Therefore, it is assumed that the terminal device 20 connects a service request to the route search server 30 and the route search server 30 provides the terminal device 20 with a service such as route guidance using a navigation function. In addition, the terminal device 20 needs to be a terminal that can receive the service after registering with the route search server 30 that provides the service.

  In the second embodiment, the configuration using the route search server 30 having the navigation service function has been described. However, the route search server 30 does not have the navigation service function, and the POI search, POI list distribution, aggregation, and totalization result distribution are performed. It is also possible to configure with a server device having such functions. Further, the terminal device 20 may be a stand-alone in-vehicle navigation device 1 having a communication function. In this case, the navigation device 1 is registered with the route search server 30 as a user and attached to a POI search or the like. The device needs to be able to receive service.
