This navigation system includes a navigation device 1 and a communication terminal 2 mounted on a vehicle 100, a communication network 3, and a distribution server 4. The navigation device 1 and the communication terminal 2 are connected by wired or wireless connection.

  The navigation device 1 detects the current position of the vehicle 100, displays a map, and indicates the detected current position of the vehicle 100 on the map. When the destination of the vehicle 100 is set for the user who is the driver of the vehicle 100, the recommended route to the destination is searched, and the vehicle 100 is guided to the destination according to the searched recommended route. The navigation device 1 stores map data used for executing such processing.

  In addition, the navigation device 1 can acquire POI information provided from the external distribution server 4. The POI information is information on various facilities called POI (Point Of Interest) and represents the names and positions of various POIs present on the map. For example, information such as the type and position of various facilities such as accommodation facilities such as inns and hotels, restaurants, gas stations, and convenience stores is acquired as POI information. The POI information includes information provided from the distribution server 4 as described above and information recorded in advance in the navigation device 1. In order to distinguish these POI information from each other, POI information provided from the distribution server 4 is hereinafter referred to as “external POI information”, and POI information recorded in advance in the navigation device 1 is referred to as “internal POI information”. .

  The external POI information can be distributed from the distribution server 4 to the navigation device 1 via the communication terminal 2 and the communication line network 3 in accordance with a user operation. Alternatively, external POI information previously downloaded from the distribution server 4 to an information terminal such as a personal computer may be recorded in the memory card 5 or USB (Universal Serial Bus) memory 6 and read by the navigation device 1. .

  The communication terminal 2 performs wireless connection with the communication line network 3 as necessary under the control of the navigation device 1. A distribution server 4 is connected to the communication line network 3. That is, the navigation device 1 is connected to the distribution server 4 via the communication terminal 2 and the communication line network 3. When the communication terminal 2 and the communication line network 3 are wirelessly connected, a radio base station (not shown) included in the communication line network 3 is used. The wireless base stations can wirelessly communicate with the communication terminals 2 in a predetermined communication area around the wireless base stations, and are scattered throughout the country. The communication terminal 2 is a mobile phone, for example. The communication network 3 is constructed by, for example, a mobile phone network or the Internet.

  The distribution server 4 is a device for distributing external POI information. The user can make a delivery request for external POI information from the navigation device 1 to the delivery server 4 by performing a predetermined operation. In response to the distribution request, the distribution server 4 selects the region corresponding to the current position of the navigation device 1 from the POI information recorded in its own database or the POI information acquired from a web server on the Internet. The POI information is extracted. Then, the extracted POI information is distributed as external POI information to the navigation apparatus 1 via the communication terminal 2 and the communication line network 3 as described above.

  The memory card 5 and the USB memory 6 are portable recording media for recording external POI information downloaded in advance from the distribution server 4 as described above. When the memory card 5 or the USB memory 6 in which the external POI information downloaded from the distribution server 4 is recorded using an information terminal such as a personal computer is set by the user, the navigation device 1 reads the external POI information therefrom. Can be obtained at.

  It should be noted that external POI information may be directly acquired from a web server on the Internet and recorded in the memory card 5 or USB memory 6 without going through the distribution server 4. Further, instead of the memory card 5 and the USB memory 6, other types of recording media, for example, various CDs and DVDs capable of writing data may be used. Any recording medium may be used as long as the POI information downloaded by an information terminal such as a personal computer can be written and the POI information can be read by the navigation device 1.

  Next, the configuration of the navigation device 1 will be described. FIG. 2 is a block diagram showing the configuration of the navigation device 1. As shown in FIG. 2, the navigation device 1 includes a control unit 10, a vibration gyro 11, a vehicle speed sensor 12, a hard disk drive (HDD) 13, a memory card reader 14, a USB interface 15, a GPS (Global Positioning System) receiving unit 16, A display monitor 17, a speaker 18, and an input device 19 are provided.

  The control unit 10 includes a microprocessor, various peripheral circuits, a RAM, a ROM, and the like, and executes various processes based on a control program and map data recorded in the HDD 13. Various processes for guiding the host vehicle, that is, the vehicle 100 to the destination are executed by the control unit 10. For example, a destination search process when setting the destination, a recommended route search process to the set destination, a current position detection process of the vehicle 100, various image display processes, a voice output process, and the like are executed. The Further, the communication terminal 2 is connected to the control unit 10, and the control unit 10 controls the communication terminal 2 to make a distribution request for external POI information from the navigation device 1 to the distribution server 4 in FIG. 1. You can also The external POI information distributed from the distribution server 4 in response to this distribution request is output to the control unit 10 via the communication terminal 2.

  The vibration gyro 11 is a sensor for detecting the angular velocity of the vehicle 100. The vehicle speed sensor 12 is a sensor for detecting the vehicle speed of the vehicle 100. Based on the detection results of these sensors, the movement amount of the vehicle 100 is obtained by calculating the motion state of the vehicle 100 at predetermined time intervals in the control unit 10.

  The HDD 13 is a non-volatile recording medium that can store and hold recorded data. Various data including the control program and map data are recorded in the HDD 13. These data recorded in the HDD 13 are read out under the control of the control unit 10 as necessary, and are used for various processes and controls executed by the control unit 10.

  The map data recorded on the HDD 13 includes route calculation data, road data, and background data. The route calculation data is data used when searching for a recommended route to the destination. The road data is data representing the shape and type of the road. In the map data, the minimum unit of each road is called a link. That is, each road in the map data is composed of a plurality of links. The background data is data representing the background of the map. Note that the background of the map is various components other than roads existing on the map. For example, rivers, railways, green zones, various structures, etc. are represented by background data.

  The map data also includes the internal POI information recorded in advance in the navigation device 1. That is, the internal POI information is recorded in the HDD 13 as part of the map data.

  FIG. 3 is a diagram illustrating an example of internal POI information recorded in the HDD 13. As shown in FIG. 3, the internal POI information is composed of a sequence of main data records as indicated by reference numeral 20 and a sequence of sub data records as indicated by reference numeral 30. As indicated by reference numeral 21, information representing the name, address, telephone number, and position coordinates of Tokyo Disneyland is recorded at the Nth main data record, for example, as POI information about Tokyo Disneyland. In addition, as information for referring to the POI information of the related facility which is a facility associated with Tokyo Disneyland in the sub data record, a sub data offset indicating the recording position of the POI information of the related facility in the sub data record, The data size of POI information of related facilities is recorded.

  On the other hand, in the sub data record, the position indicated by the sub data offset and the data size corresponding to Tokyo Disneyland has the name of the related facility as POI information about the related facility of Tokyo Disneyland, as indicated by reference numeral 31. And position coordinates are recorded. That is, the names and position coordinates of the first parking lot, the second parking lot, and the third parking lot that are attached to Tokyo Disneyland are recorded in the sub data record.

  Note that the recording format of the internal POI information as described above is merely an example, and other recording formats may be used. As long as information necessary for use in the navigation device 1 is appropriately expressed for various facilities (POI) on the map, and a specific facility can be referred to a related facility associated with the facility, Any recording format may be adopted for recording the POI information in the HDD 13.

  In the above description, the map data is recorded on the HDD 13 in the navigation device 1. However, the map data may be recorded on something other than the HDD. For example, a flash memory or the like may be used instead of the HDD.

  The memory card reader 14 is a part for reading external POI information recorded on the memory card 5. When the memory card 5 is set in the insertion slot provided in the memory card reader 14, the external POI information recorded on the memory card 5 is read out by the memory card reader 14 under the control of the control unit 10, and the HDD 13 Is output. As a result, the external POI information is read from the memory card 5 in the navigation device 1 and recorded in the HDD 13.

  The USB interface 15 has a slot portion for loading the USB memory 6. When the USB memory 6 is loaded in this slot part, the external POI information recorded in the USB memory 6 is read out by the USB interface 15 under the control of the control part 10 and a predetermined interface process is performed. The data is output to the HDD 13. As a result, the external POI information is read from the USB memory 6 in the navigation device 1 and recorded in the HDD 13.

  The GPS receiver 16 receives a GPS signal transmitted from a GPS satellite and outputs it to the controller 10. The GPS signal includes information on the position and transmission time of the GPS satellite that transmitted the GPS signal as information for obtaining the reception position and the current time. Therefore, by receiving GPS signals from a predetermined number or more of GPS satellites, the reception position and the current time can be calculated based on these pieces of information. Based on the reception position calculated based on the GPS signal received by the GPS receiver 16 and the movement amount of the vehicle 100 calculated based on the detection results of the vibration gyro 11 and the vehicle speed sensor 12 described above, the vehicle 100 current positions are determined.

  The display monitor 17 is a device for displaying various screens in the navigation device 1 and is configured using a liquid crystal display or the like. The display monitor 17 displays a map screen. The contents of the screen displayed on the display monitor 17 are determined by screen display control performed by the control unit 10. The display monitor 17 is installed at a position where the user can easily see, for example, on the dashboard of the vehicle 100 or in the instrument panel.

  The speaker 18 outputs various audio information related to vehicle travel under the control of the control unit 10. For example, route guidance voice for guiding the vehicle to the destination according to the recommended route, various warning sounds, and the like are output.

  The input device 19 is a device for a user to perform various input operations for operating the navigation device 1, and includes various input switches. The user operates the input device 19 to input, for example, the name of a facility or point desired to be set as a destination, select a destination from registered locations registered in advance, or display a map in an arbitrary direction. Or scroll. The input device 19 can be realized by an operation panel, a remote controller, or the like. Alternatively, the input device 19 may be realized by a touch panel integrated with the display monitor 17.

  When the user operates the input device 19 to set the destination, the navigation device 1 searches for a route to the destination where the total of the link costs is minimum, for example, based on the link cost set in the map data. The route is set as a recommended route. The recommended route set in this way is displayed on the map in a display form distinguishable from other roads. Thereafter, the navigation device 1 displays a map around the current location, and guides the vehicle 100 to the destination according to the set recommended route.

  Next, a process executed when setting the destination in the navigation device 1 will be described. When setting the destination, the navigation device 1 determines the internal POI information recorded in the HDD 13 or the external POI information acquired from the outside via the wireless communication, the memory card 5 or the USB memory 6 in accordance with a user operation. Based on the above, the facility (POI) to be set as the destination is selected. At this time, when a facility is selected based on the external POI information, the same facility as that facility is also searched from the internal POI information. As a result, if the information on the facility is also included in the internal POI information, the related facility corresponding to the facility is identified based on the sub data offset and the data size as described in FIG. The POI information of the facility is acquired from the internal POI information. Then, the display monitor 17 displays the locations of the facility and related facilities on the map.

  Here, the internal POI information and the external POI information may be provided from different providers. Therefore, even if it is the same facility, the facility name and address may not completely match between both POI information. For example, some of the facility names may be different, or some characters used in the facility name or address may be different in half-width and full-width. In addition, the location of the facility indicated by the position coordinates of both POI information is not the same and may be slightly shifted. Therefore, when searching the same facility as the facility selected based on the external POI information in the internal POI information, it is necessary to take these differences into consideration.

  FIG. 4 is a diagram showing an example of the destination setting screen displayed on the display monitor 17 by the processing described above. On this destination setting screen, a destination candidate list 40 and a map screen 50 are displayed.

  In the destination candidate list 40, items indicated by reference numerals 41 to 45 are displayed in a list. Of these items, item 41 represents Tokyo Disneyland, which is a facility selected by the user's operation based on the external POI information. On the other hand, the item 42 represents Tokyo Disneyland searched based on internal POI information as the same facility as the selected facility. In the internal POI information, information as indicated by reference numeral 21 in FIG. 3 is recorded as POI information for this facility. Items 43, 44, and 45 represent a first parking lot, a second parking lot, and a third parking lot that are attached to Tokyo Disneyland as related facilities corresponding to the facility represented by the item 42, respectively. . In the internal POI information, information as indicated by reference numeral 31 in FIG. 3 is recorded as POI information for each of these related facilities.

  On the map screen 50, icons 51 to 55 indicating the positions of the facilities corresponding to the items 41 to 45 on the map are displayed. That is, the icon 51 indicates the position of Tokyo Disneyland corresponding to the item 41, and the icon 52 indicates the position of Tokyo Disneyland corresponding to the item 42. Icons 53, 54, and 55 indicate the positions of the related facilities corresponding to the items 43, 44, and 45, that is, the first parking lot, the second parking lot, and the third parking lot, respectively. Note that the icon 51 and the icon 52 are respectively displayed at different locations on the map screen 50 even though they indicate the same location of Tokyo Disneyland. This is because the position coordinates do not match between the internal POI information and the external POI information as described above.

  When the user designates any of the items 41 to 45 in the destination candidate list 40 by operating the input device 19 on the destination setting screen in FIG. 4, the facility corresponding to the item is set as the destination. Then, a route from the current position of the vehicle 100 to the set destination is searched, and guidance of the vehicle 100 is started using the route as a recommended route.

  FIG. 5 shows a flowchart of processing executed in the navigation device 1 when setting the destination as described above. This flowchart shows the control of the navigation device 1 when the user instructs the navigation device 1 to acquire external POI information and set a destination by performing a predetermined operation using the input device 19. This is executed in the unit 10.

  In step S10, the control unit 10 acquires external POI information. Here, as described above, the external POI information is acquired from the distribution server 4 through wireless communication performed using the communication terminal 2. Alternatively, external POI information is acquired via the memory card 5 or the USB memory 6 by reading the external POI information stored in the memory card 5 or the USB memory 6 using the memory card reader 14 or the USB interface 15.

  In step S20, the control unit 10 selects a POI based on the external POI information acquired in step S10. Here, for example, each POI represented by the acquired external POI information is displayed in a list on the display monitor 17, and by selecting one of the POIs by operating the input device 19, the POI based on the external POI information is displayed. Make a selection. Or it is good also as making a user input the kind, name, etc. of POI which it is going to select, and searching applicable POI from external POI information based on the input result.

  In step S30, the control unit 10 searches the internal POI information recorded in the HDD 13 for a POI that satisfies a predetermined matching condition for the POI selected in step S20. Here, based on the facility name, telephone number, address, etc. recorded in the external POI information for the selected POI, the POI in which the facility name, telephone number, or address having the contents matching these are set as the internal POI information Search from within. At this time, it is not always necessary to use all of the facility name, telephone number, and address. In addition, in consideration of the difference due to the difference in the provider as described above, the same facility name may be used if it does not completely match the facility name or address in the external POI information, but partially matches. It is preferable to determine that the address is an address. In this way, for the POI selected in step S20, a POI satisfying a predetermined matching condition based on at least one of the name, address and telephone number of the POI in the external POI is recorded in the HDD 13. Search from the internal POI information.

  In step S40, the control unit 10 determines whether or not a POI satisfying the matching condition has been searched in step S30. If a POI satisfying the above matching condition can be retrieved from the internal POI information at the time of execution of step S30, the process proceeds to step S50. On the other hand, if there is no POI satisfying the matching condition in the internal POI information, it is determined that no POI satisfying the matching condition has been searched, and the process proceeds to step S80.

  In step S50, the control unit 10 calculates the inter-coordinate distance between the external POI information and the internal POI information for the POI searched in step S30. That is, the inter-coordinate distance is calculated by obtaining the difference between the position coordinates in the external POI information and the position coordinates in the internal POI information and calculating the distance corresponding to this difference.

  In step S60, the control unit 10 determines whether or not the inter-coordinate distance calculated in step S50 is within a predetermined distance. If the distance between coordinates is a predetermined reference distance that can be regarded as the same facility, for example, within 100 m, the process proceeds to step S70, and if not, the process proceeds to step S80. Thereby, it is determined whether or not the POI searched in step S30 is the same POI selected in step S20. Note that the reference distance used for the determination at this time may be changed according to the type of the POI. For example, for a large-scale facility such as an amusement park or a shopping mall, it is preferable to set the reference distance larger than other facilities.

  By executing the processes in steps S30 to S60 described above, the same POI as the POI selected in step S20 is searched for in the internal POI information recorded in the HDD 13. That is, when the POI satisfying a predetermined matching condition exists in the internal POI information for the selected POI, and the distance between these POIs is within a predetermined distance, the same POI as the selected POI is Retrieved from internal POI information. On the other hand, if there is no POI satisfying the matching condition for the selected POI in the internal POI information, or if the distance between the selected POI and the POI satisfying the matching condition is greater than or equal to a predetermined distance, the selection is made in step S20. The same POI as the POI that has been selected is not retrieved from the internal POI information.

  In step S70, the control unit 10 identifies the related facility associated with the POI searched in step S30 based on the internal POI information recorded in the HDD 13. Here, by referring to the sub data offset and data size described in FIG. 3 in the internal POI information, the sub data record as the POI information of the related facility for the POI is read. Based on the POI information of the related facility thus read out, the related facility associated with the POI is specified, and the name and position of the related facility are obtained. If step S70 is performed, it will progress to step S90.

  In step S80, the control unit 10 searches for a parking lot existing in the vicinity of the POI selected in step S20. Here, a parking lot existing within a predetermined range from the POI, for example, within a range of 100 m, is searched as a neighboring parking lot. Thereby, when a related facility cannot be searched for the selected POI, a parking lot around the POI is searched instead of the related facility. If step S80 is performed, it will progress to step S90.

  In step S <b> 90, the control unit 10 displays the destination setting screen on the display monitor 17. At this time, when the related facility is specified by executing step S70, the POI selected in step S20, the POI searched in step S30 as the same facility as the POI, and these are specified in step S70. The names of the related facilities are displayed in the destination candidate list 40 as a list. Further, the positions of these POIs and related facilities are displayed on the map screen 50. As a result, the destination setting screen as shown in FIG. 4 is displayed on the display monitor 17. On the other hand, when the neighboring parking lot is searched by executing step S80, the names of the POI selected in step S20 and the neighboring parking lot searched for in step S80 for the POI are entered in the destination candidate list 40. Display a list. Further, the position of these POIs and neighboring parking lots is displayed on the map screen 50. Thereby, the selected POI and its neighboring parking lot are simultaneously displayed on the map on the display monitor 17 as in the destination setting screen of FIG.

  If step S90 is performed, the control part 10 will complete | finish the process shown to the flowchart of FIG. Thereafter, when any POI is selected by the user on the destination setting screen displayed in step S90, the POI is set as the destination. Then, a route from the current position of the vehicle 100 to the set destination is searched, and guidance of the vehicle 100 is started using the route as a recommended route.

  According to the embodiment described above, the following operational effects are obtained.

(1) The navigation device 1 selects a POI based on the external POI information by the processing of the control unit 10 (step S20). Further, based on the internal POI information recorded in the HDD 13, the same POI as the POI selected in step S20 is searched (steps S30 to S60). Then, the related facility associated with the POI is specified based on the internal POI information (step S70), and the destination setting screen as shown in FIG. 4 is displayed on the display monitor 17 (step S90). Thereby, the POI selected in step S20, the POI searched in steps S30 to S60, and the related facilities associated with the POI in the internal POI information are simultaneously displayed on the map. Since it did in this way, based on multiple types of facility information like external POI information and internal POI information, a user can confirm easily the facility relevant to the selected facility.

(2) The above-mentioned related facilities include a parking lot corresponding to a specific facility such as Disneyland. Therefore, the user can easily confirm the position of the parking lot to be parked when he / she goes to the POI only by specifying one of the POIs.

(3) The navigation device 1 obtains external POI information from the outside through the memory card 5 or the USB memory 6 that is a wireless communication or portable recording medium using the communication terminal 2 by the processing of the control unit 10. (Step S10). Thereby, external POI information can be easily acquired as needed.

(4) The external POI information and the internal POI information each include at least one of the name, address, and telephone number of each POI. The control unit 10 searches the internal POI information for a POI that satisfies a predetermined matching condition based on at least one of the name, address, and telephone number of the POI selected in step S20 in the external POI information (step S30). ). Since it did in this way, in consideration of the difference by the difference in a provider between external POI information and internal POI information, POI same as POI selected at Step S20 can be searched certainly from internal POI information. it can.

(5) The external POI information and the internal POI information further include the position of each POI. The control unit 10 calculates the distance between the position of the POI in the external POI information and the position of the POI in the internal POI information (step S50), and based on the calculation result, the match retrieved in step S30 It is determined whether or not the POI satisfying the condition is the same POI as the POI selected in step S20 (step S60). In this way, it is reliably determined whether or not the POI selected in step S20 and the POI searched in step S30 are the same POI. Therefore, a search for the same POI as the selected POI is performed. Accuracy can be improved.

(6) When the same POI as the POI selected in step S20 cannot be searched in steps S30 to S60, the control unit 10 searches for a parking lot within a predetermined range from the POI (step S80). Then, on the destination setting screen displayed in step S90, the POI selected in step S20 and the parking lot searched in step S80 are simultaneously displayed on the map. Since it did in this way, even if it is a case where the POI same as POI selected by step S20 cannot be searched, the position of the parking lot which should be parked when it goes to that POI can be confirmed easily. .

  In the above embodiment, when a POI is selected based on external POI information, the same POI as that POI is searched from the internal POI information, and these POIs and related facilities are displayed on a map. Explained. However, when a POI is selected based on internal POI information, the same processing may be performed by searching the external POI information for the same POI as that POI.

  Moreover, in the said embodiment, although the parking lot was demonstrated as an example of a related facility, facilities other than a parking lot are good also as a related facility. For example, regarding complex facilities such as parks, leisure lands, and shopping malls where various facilities exist on the site, the facilities on the site can be used as related facilities. Or you may enable it for a user to set arbitrary facilities as related facilities.

  Furthermore, in the above-described embodiment, an example has been described in which internal POI information recorded in the HDD 13 and external POI information acquired from the outside via wireless communication or the memory card 5 or the USB memory 6 are used. The POI information may be used.
