(S200).

  For example, the peripheral information acquisition unit 200 extracts the peripheral information ID included in the hatched area illustrated in FIG. 10 from the peripheral information storage unit 210. Here, the hatched area is based on the current position “coordinate (X8, Y3)” indicated by a black triangle, the passing point 1 “coordinate (X8, Y5)” indicated by a white circle “1”, and the radius “10”. Boundary line 320 of a semicircle having a convex portion on the front “north” side, current position “coordinates (X8, Y3)”, passing point 1 “coordinates (X8, Y5)”, white circle “2” To the passing point 2 “coordinates (X9, Y7)”, the passing point 3 “coordinates (X7, Y10)” indicated by the white circle “3”, and the destination “coordinates (X8, Y13)” indicated by stars. It is surrounded by a boundary line 310 that is a distance “5” half the radius “10” from the path 300 specified based on the path 300 and a boundary line 330 between the front “north” and the rear “south”. The peripheral information acquisition unit 200 extracts the peripheral information ID “F0104” and the like stored in the peripheral information storage unit 210 using the shaded area as the location.

  The peripheral information acquisition unit 200 generates response data including an icon image based on the extracted peripheral information ID (S210). Specifically, the peripheral information acquisition unit 200 firstly associates the extracted peripheral information ID “F0104” with the icon image “Restaurant D.jpg” stored in the peripheral information storage unit 210 and the location “coordinate ( X6, Y8) ”and the count value“ 60 ”of the previous day stored in the count value storage unit 230 in association with the extracted peripheral information ID“ F0104 ”. Similarly, the peripheral information acquisition unit 200 acquires the icon image, the location, and the previous day's count value for other extracted peripheral information IDs. Then, as shown in FIG. 11, the peripheral information acquisition unit 200 generates response data including the acquired icon image, the location, and the previous day's count value in association with the peripheral information ID (the same step). The peripheral information acquisition unit 200 transmits the generated response data to the transmission / reception unit 180 of the car navigation device 10 (same step). Then, the peripheral information acquisition unit 200 stands by until reception of the next peripheral information request data. The transmission / reception unit 180 stores the received response data in the peripheral information temporary storage unit 142 (S140).

  The peripheral information display unit 120 extracts an icon image to be displayed from the icon images included in the response data stored in the peripheral information temporary storage unit 142 (S145). For example, the peripheral information display unit 120 refers to the peripheral information ID and the previous day's count value included in the response data, and as an icon image to be displayed, the upper three of the previous day's count values having a large number of previous day's counts Extract icon images. In the example shown in FIG. 11, the peripheral information display unit 120 has three icon images “restaurant E. jpg”, “restaurant L. jpg”, “restaurant” with the most counted values for the previous day for icon images indicating restaurants. D.jpg "is extracted. Similarly, the peripheral information display unit 120 extracts all icon images “Pachinko J.jpg” and “sport store K.jpg” as icon images to be displayed for icon images other than restaurants. Instead, the peripheral information display unit 120 may receive an input of the type of peripheral information to be displayed from the user, and extract an icon image of the peripheral information ID corresponding to the received type.

  The peripheral information display unit 120 reads out the location included in the extracted icon image and the response data stored in the peripheral information temporary storage unit 142 in association with the extracted icon image, and is displayed on the map display unit 110. The icon image is displayed on the display 106 in a superimposed manner (S150). In the example illustrated in FIG. 12, the peripheral information display unit 120 displays the icon image “restaurant E.jpg” on the basis of the corresponding location “coordinates (X6, Y8)”. The information is displayed on the display 106 so as to be superimposed on the 350 map. The same applies to the icon images “restaurant L.jpg”, “restaurant D.jpg”, “pachinko J.jpg”, and “sport store K.jpg”. As described above, the peripheral information display unit 120 displays the icon image in the range 340 that is narrower than the map of the region 350 displayed by the map display unit 110 on the display 106.

  The history storage unit 144 stores the location, display start date and time, and display end date and time in association with the peripheral information ID for the icon image displayed by the peripheral information display unit 120 (S155).

  The peripheral information display unit 120 determines whether or not to end the display of the icon image (S160). For example, the peripheral information display unit 120 determines that the display of the peripheral information is to be ended when information indicating that the display of the peripheral information should be ended is received from the driver via the operation button of the operation panel 104. When the peripheral information display unit 120 determines in step S160 that display of the peripheral information is to be ended (S160: Yes), this flowchart ends. On the other hand, when the peripheral information display unit 120 determines in step S160 that the display of the peripheral information is not finished (S160: Yes), the process returns to step S100.

  In step S120, the arrival area calculation unit 152 calculates the arrival area by calculating information for specifying the arrival area that can be reached within the predetermined time “20 minutes”. It may be less than a minute or may be longer than 20 minutes.

  In addition, instead of calculating the reachable area within the circle from the current position, the reaching area calculation unit 152 calculates two or more coordinates that can be reached at a predetermined time, and connects the two or more coordinates. The arrival area may be calculated by As an example, the arrival area calculation unit 152 in FIG. 10 includes coordinates “(X5, Y3)”, coordinates “(X11, Y3)”, coordinates “(X5, Y6)”, coordinates “(X11, Y6)”, and coordinates A baseball home base type region that narrows in the traveling direction connecting “(X8, Y9)” with a straight line may be calculated as the reaching area. As a result, it is possible to easily calculate the arrival area that places more importance on the current position than the destination. As another example, the arrival area calculation unit 152 proceeds in FIG. 10 by connecting the coordinates “(X8, Y3)”, the coordinates “(X5, Y6)”, and the coordinates “(X11, Y6)” with straight lines. A triangular area extending in the direction may be calculated as the arrival area. As a result, it is possible to easily calculate an arrival area that places more importance on the destination than on the current position.

  In step S135, the transmission / reception unit 180 generates the peripheral information request data based on the information specifying the route and the information specifying the arrival area. Either of the information specifying the route or the information specifying the arrival area is used. Peripheral information request data may be generated based on one.

  In step S200, the peripheral information acquisition unit 200 calculates the boundary line 310 using a distance that is half the radius 322, but this distance may be another distance. However, this distance is preferably shorter than the radius 322.

  In step S145, the peripheral information display unit 120 extracts the top three icon images having the most previous day count values, but may extract the top two or less icon images or the top four or more icon images. In addition, the peripheral information display unit 120 may extract icon images having a count value for the previous day that is greater than a reference value. Further, the peripheral information display unit 120 may extract icon images based on the reference values for the past week and the past month instead of the count value of the previous day.

  FIG. 13 is a flowchart illustrating another example of the operation of the peripheral information display system 40. The peripheral information display system 40 shown in FIG. 13 displays peripheral information of an area that is likely to stop by a break or the like during the movement to the destination. In this case, the main body 100 of the car navigation device 10 includes a scheduled area calculation unit instead of the arrival area calculation unit 152. In the following description, it is assumed that the start conditions and the preconditions in this flowchart are the same as those in the flowchart shown in FIG. Further, the left side of the flowchart shows the operation of the car navigation device 10, and the right side shows the operation of the server 20.

  Steps S500 to S515 are the same as steps S100 to S115 shown in FIG. That is, the current position acquisition unit 132 and the speed calculation unit 150 transfer information to be transferred to the arrival area calculation unit 152 to the scheduled area calculation unit in the flowchart shown in FIG. In step S520, the scheduled area calculation unit determines that the automatic vehicle is to be located after a predetermined time has elapsed based on the average speed calculated by the speed calculation unit 150 and the current position acquired by the current position acquisition unit 132. A scheduled area is calculated (S520). Specifically, the scheduled area calculation unit multiplies the average speed “30 km / h” by a predetermined constant “0.75” to set the lower limit speed “22.5 km / h” to the average speed “30 km / h”. Is multiplied by a constant “1.25” to calculate an upper limit speed “37.5 km / h”. Then, the scheduled area calculation unit calculates the maximum reachable area “region having a radius of 37.5 km from the coordinates (X8, Y3) that is the current position” that can be reached at the upper limit speed “37.5 km / h” at a predetermined time “60 minutes”. From the minimum reachable area “region of radius 22.5 km from the coordinates (X8, Y3) as the current position” that can be reached at the lower limit speed “22.5 km / h” at the predetermined time “60 minutes”. The area is calculated as a scheduled area (same step). The scheduled area calculation unit delivers information specifying the calculated scheduled area to the map display unit 110 and the transmission / reception unit 180.

  Steps S525 and S530 are the same as steps S125 and S130 shown in FIG. In step S535, the transmission / reception unit 180 requests peripheral information based on the information for specifying the route calculated by the route search unit 136 and the information for specifying the planned area calculated by the planned area calculation unit. Data is generated (S535). The peripheral information display unit 120 transmits the generated peripheral information request data to the peripheral information acquisition unit 200 of the server 20 (same step).

  Steps S600 and S610 are the same as steps S200 and S210 shown in FIG. Steps S540 to S555 are the same as steps S140 to S155 shown in FIG. In step S560, the peripheral information display unit 120 determines whether or not to end the display of the icon image (S560). When the peripheral information display unit 120 determines in step S560 that the display of the peripheral information is to be ended (S560: Yes), this flowchart ends.

  On the other hand, when it is determined in step S560 that the display of the peripheral information is not finished (S560: No), the peripheral information display unit 120 determines whether or not a predetermined time “60 minutes” has elapsed (S565). When it is determined in step S565 that the predetermined time “60 minutes” has elapsed (S565: Yes), the process returns to step S500. On the other hand, when it is determined in step S565 that the predetermined time “60 minutes” has not elapsed (S565: No), the process returns to step S560.

  Note that the predetermined time in step S520 and the predetermined time in step S565 are preferably the same. The predetermined time is set in advance by the passenger as a rest interval, for example. When the main body 100 of the car navigation device 10 includes a planned area calculation unit instead of the arrival area calculation unit 152, the history storage unit 144 displays an icon image of the peripheral information displayed by the peripheral information display unit 120. It is preferable to store them in association with the coordinates. For example, when a driver or the like presses an operation button on the operation panel 104, the map display unit 110 and the peripheral information display unit 120 preferably display the peripheral information displayed in the past in association with the map. Thereby, it is possible to display only the peripheral information of an area where there is a high possibility of taking a rest after a predetermined time.

  FIG. 14 is a flowchart showing an example of the operation of the peripheral information display system 40. FIG. 15 shows an example of the payload of billing information transmitted to the server 20. The flowchart shown in FIG. 14 starts when the car navigation device 10 starts operating first after that when the current position acquired by the current position acquisition unit 132 has not changed over a predetermined time. Further, it is assumed that the count value storage unit 230 stores the information shown in FIG. 7 at the start of this flowchart. It is assumed that the start of this flowchart is 12:50 on August 5, 2006. Further, the left side of the flowchart shows the operation of the car navigation device 10, and the right side shows the operation of the server 20.

  The transmission / reception unit 180 determines whether or not communication with the public wireless LAN base station 30 is possible (S300). In step S300, when the transmission / reception unit 180 determines that communication with the public wireless LAN base station 30 is possible (S300: Yes), the stop determination unit 160 has at least one of the locations stored in the history storage unit 144. Then, by determining whether or not it is in the vicinity of the public wireless LAN base station 30, it is determined whether or not the automatic vehicle has stopped near the position indicated by the icon image stored in the history storage unit 144 (S310). ). Specifically, the stop determination unit 160 is stored in the history storage unit 144 when at least one of the locations stored in the history storage unit 144 is one position within a radius of 50 m from the current position. It is determined that at least one of the locations is in the vicinity of the public wireless LAN base station 30.

  In step S310, when the stop determination unit 160 determines that the automatic vehicle has stopped near the position indicated by the icon image stored in the history storage unit 144 (S310: Yes), the stop determination unit 160 The location that is in the vicinity of the public wireless LAN base station 30, the peripheral information ID associated with the location, the display start date and time, and the display end date and time are read from the history storage unit 144 and passed to the billing information generation unit 170. The billing information generation unit 170 generates billing information shown in FIG. 15 based on the information received from the stop determination unit 160 (S320). Here, the plurality of display start dates and times shown in FIG. 15 indicate that an icon image indicating this location has been displayed on the automatic vehicle a plurality of times such as on the outward trip and the return trip. The display time is calculated from a set of display start date and time and display end date and time. The stop date and time is, for example, the date and time when the billing information is generated.

  The transmission / reception unit 180 transmits the billing information generated by the billing information generation unit 170 to the peripheral information acquisition unit 200 of the server 20 (S330). The peripheral information acquisition unit 200 stores the charging information received from the transmission / reception unit 180 in the charging information storage unit 240. And this flowchart is complete | finished.

  On the other hand, if the transmission / reception unit 180 determines in step S300 that communication with the public wireless LAN base station 30 is not possible (S300: No), the stop determination unit 160 displays the icon image stored in the history storage unit 144 in step S310. If it is determined that the automatic vehicle has not stopped near the position indicated by (No in S310), Steps S330 and S340 are skipped, and the present flowchart ends.

  In step S310, the stop determination unit 160 determines that at least one of the locations is in the vicinity of the public wireless LAN base station 30 when the location is one position within a radius of 50 m from the current location. However, this radius may be another distance that is interpreted as a neighborhood.

  In this embodiment, the transmission / reception unit 180 generates the peripheral information request data based on the information for specifying the route or the information for specifying the arrival area, but instead of this, the map display unit 110 displays the information. Information indicating the size of the map area to be displayed may be transmitted to the peripheral information acquisition unit 200. In this case, the peripheral information acquisition unit 200 stores the information in the peripheral information storage unit 210 in association with one position in an area narrower than the map area indicated by the information indicating the size of the map area transmitted from the transmission / reception unit 180. The stored peripheral information may be read and transmitted to the transmission / reception unit 180.

  Further, in the present embodiment, the stop determination unit 160 communicates with the public wireless LAN base station 30 provided in the vicinity of the stop spot stored in the history storage unit 144 by the transmission / reception unit 180. However, the condition is not limited to this, although it is determined that the motor vehicle has stopped near the location of the stop-off spot. In the stop determination unit 160, the distance between the position where the automatic vehicle specified from the current position acquired by the current position acquisition unit 132 stops and the position indicated by the icon image stored in the history storage unit 144 is within a predetermined range. In this case, it may be determined that the motor vehicle has stopped near the location of the stop-off spot.

  In the present embodiment, the peripheral information display unit 120 of the car navigation device 10 extracts the icon image to be displayed based on the count value from the peripheral information icon images in the predetermined area. It is not limited to this. As another example, the peripheral information acquisition unit 200 of the server 20 extracts an icon image to be displayed based on the count value from the peripheral information icon images in a predetermined area, and the extracted icon image is car-navigated. You may transmit to the transmission / reception part 180 of the apparatus 10. FIG.

  Further, in FIG. 6 of the present embodiment, the peripheral information storage unit 210 stores a spot name, an icon image, and a location in association with the peripheral information ID. In addition to this, detailed information on the spot, and The storage date and time when the detailed information is stored in the peripheral information storage unit 210 or the update date and time when the stored detailed information is updated may be stored. When the peripheral information storage unit 210 stores the detailed information and the update date and time, the peripheral information acquisition unit 200 of the server 20 associates the detailed information and the update date and time with the peripheral information ID and transmits and receives the detailed information and the update date and time. The peripheral information display unit 120 may extract an icon image with a new update date and time as an icon image to be displayed. Further, as described above, the peripheral information acquisition unit 200 of the server 20 may extract an icon image with a new update date and time instead of the peripheral information display unit 120. The peripheral information display unit 120 receives selection of an icon image from the passenger and displays detailed information on peripheral information corresponding to the received icon image on the display 106. Then, the history storage unit 144 stores the fact that the detailed information is displayed on the display 106 by the peripheral information display unit 120 in association with the peripheral information ID. In this case, the charging information generation unit 170 may generate charging information on the condition that the detailed information is displayed on the display 106 by the peripheral information display unit 120.

  In FIG. 1 of the present embodiment, one server 20 and one public wireless LAN base station 30 are described. However, it is preferable that a plurality of servers 20 and a plurality of public wireless LAN base stations 30 are installed. Each of the plurality of servers 20 is connected to each other via a network such as an optical fiber. Also, some of the installed servers 20 may include the peripheral information storage unit 210. The server 20 that does not include the peripheral information storage unit 210 may access the peripheral information storage unit 210 included in the other server 20 via a network. Similarly, some of the installed servers 20 may include a count value storage unit 230 and a billing information storage unit 240. The server 20 that does not include the count value storage unit 230 or the billing information storage unit 240 may access the count value storage unit 230 or the billing information storage unit 240 included in the other server 20 via a network.

  The car navigation device 10 and the server 20 may communicate with each other using a mobile phone or the like. That is, the car navigation device 10 and the server 20 communicate with each other via the public wireless LAN base station 30, and instead of a mobile phone base station, a radio access network including a base control station, and a core including an exchange. You may communicate with each other via a network. In this case, the server 20 may be installed on the radio access network or the core network.

  However, even when the car navigation device 10 and the server 20 communicate with each other using a mobile phone or the like, the transmission / reception unit 180 of the car navigation device 10 is provided with a public wireless LAN provided in the vicinity of the position indicated by the peripheral information. It is preferable to provide a short-range wireless communication device that communicates with the base station 30 wirelessly. The stop determination unit 160 preferably determines that the automatic vehicle has stopped near the position indicated by the peripheral information on the condition that the short-range wireless communication device communicates with the public wireless LAN base station 30. Further, when the car navigation device 10 and the server 20 communicate with each other using a mobile phone or the like, the location information and the peripheral information obtained from the GPS satellite 14 indicate that instead of providing the public wireless LAN base station 30.
