For example, the ID acquisition unit 162 sets the passenger ID that has been most duplicated among the passenger IDs acquired from the short-range communication unit 172, the weight detection unit 174, the seat position detection unit 176, and the voice detection unit 178 as the current passenger ID. The passenger ID may be determined as the passenger ID of the passenger.

  Further, in the registration mode for registering the passenger ID, the ID acquisition unit 162 stores the telephone number and the like acquired by the short-range communication unit 172 or the like in the ID storage unit 164 in association with the new passenger ID. Note that the ID acquisition unit 162 switches between the acquisition mode and the registration mode when receiving input of mode switching information via the operation button of the operation panel 104.

  The driver identification unit 180 includes an ID acquisition unit and an ID storage unit (not shown). Since these functions are the same as those of the ID acquisition unit 162 and the ID storage unit 164 included in the passenger identification unit 160, description thereof will be omitted.

  The map display unit 110 calculates at least one of the routes from the current point to the destination calculated based on the current position acquired by the current position acquisition unit 132 and the destination acquired by the destination reception unit 130. The map is read from the map storage unit 140 and displayed on the display 106.

  The attribute storage unit 150 stores the passenger's attribute in association with the passenger ID. For example, as shown in FIG. 4A, the attribute storage unit 150 associates the passenger's gender classification, the passenger's age, and the passenger's occupation classification as the basic attribute information 152 in association with the passenger ID. Store.

  In addition, the attribute storage unit 150 stores the attribute associated with the peripheral information selected when the fellow passenger was in the past in association with the fellow passenger ID. Specifically, as shown in FIG. 4B, the attribute storage unit 150 is specified by the peripheral information ID that identifies the peripheral information in association with the fellow passenger ID as the history attribute information 154 and the peripheral information. A peripheral information type indicating the type of stop-off spot such as a store or a famous place, and a selection date and time indicating the date and time when the peripheral information is selected are stored. Here, the peripheral information includes image information related to a stop spot existing in an area indicated on the map displayed on the display 106 by the map display unit 110, and an icon image related to the stop spot. The peripheral information may further include voice information such as voice guidance. The attribute storage unit 150 is an example of a history storage unit.

Details of the operation of the server 20 will be described later.

  The peripheral information temporary storage unit 142 temporarily stores peripheral information transmitted from the server 20 via the public wireless LAN base station 30 and attributes associated with the peripheral information. Specifically, the peripheral information temporary storage unit 142 temporarily stores an icon image, peripheral information type, and location of the peripheral information in association with the peripheral information ID.

  In addition, the peripheral information display unit 120 reads an icon image of the peripheral information stored in the peripheral information temporary storage unit 142 and displays the icon image on the display 106 so as to be superimposed on the map displayed by the map display unit 110.

  Further, when the peripheral information display unit 120 receives an input to the icon image of the displayed peripheral information via the operation button of the operation panel 104, the peripheral information display unit 120 corresponds to the passenger ID related to the passenger when the input is received. In addition, the peripheral information ID and the peripheral information type stored in the peripheral information temporary storage unit 142 are stored as history attribute information 154 in the attribute storage unit 150. In this case, the peripheral information display unit 120 stores the date and time when the input is accepted as the selected date and time. If the peripheral information display unit 120 determines that the automatic vehicle has stopped at the location of the stop spot indicated by the icon image, for example, based on information from the GPS satellite 14, for example, The peripheral information ID and the peripheral information type stored in the peripheral information temporary storage unit 142 in association with the icon image may be stored as the history attribute information 154 in the attribute storage unit 150. In this case, the peripheral information display unit 120 stores the stop date and time as the selected date and time.

  The main body 102 of the car navigation device 100 may further include a speed calculation unit (not shown) and a scheduled area calculation unit (not shown). The speed calculation unit calculates an average speed of the motor vehicle for a predetermined time in the past. The scheduled area calculation unit calculates a planned area where the automatic vehicle is scheduled to be located after a predetermined time has elapsed based on the average speed calculated by the speed calculation unit and the current position acquired by the current position acquisition unit 132. .

  FIG. 5 is a block diagram of the server 20. FIG. 6 shows an example of information stored in the peripheral information storage unit 210. As shown in FIG. 5, the server 20 includes a peripheral information acquisition unit 200 and a peripheral information storage unit 210. The peripheral information storage unit 210 stores the peripheral information in association with the passenger attributes. For example, as illustrated in FIG. 6, the peripheral information storage unit 210 associates the peripheral information with the peripheral information ID, the spot information indicating the name of the stop spot specified by the peripheral information type, the basic attribute that is an attribute of the passenger, and the peripheral information. , Location, and two types of icon images are stored. Here, one of the two types of icon images is an emphasized image having a conspicuous appearance as compared with the other icon image.

  The peripheral information acquisition unit 200 receives attributes from the peripheral information display unit 120 via the public wireless LAN base station 30. The peripheral information acquisition unit 200 reads an icon image or the like stored in the peripheral information storage unit 210 in association with the received attribute. The peripheral information acquisition unit 200 transmits the read icon image or the like to the peripheral information temporary storage unit 142 via the public wireless LAN base station 30.

  FIG. 7 is a flowchart showing an example of the operation of the peripheral information display system 40. FIG. 8 shows an example of the payload of the peripheral information request data transmitted to the server 20. FIG. 9 shows an example of the payload of response data transmitted to the peripheral information display device 10. FIG. 10 shows an example of display on the display 106.

  The flowchart shown in FIG. 7 starts when the short-range communication unit 172 receives the telephone number of the mobile phone held by the passenger before departure. Further, it is assumed that the destination receiving unit 130 receives the input of the destination at the start of this flowchart. Also, at the start of this flowchart, the ID storage unit 164 stores the information shown in FIG. 3, and the attribute storage unit 150 stores the basic attribute information 152 shown in FIG. 4A and FIG. 4B. It is assumed that the history attribute information 154 shown in FIG. Further, it is assumed that the peripheral information storage unit 210 stores the information shown in FIG. 6 at the start of this flowchart. It is assumed that the start of this flowchart is 11:00 on August 12, 2006. Further, the left side of the flowchart shows the operation of the peripheral information display device 10, and the right side shows the operation of the server 20.

  The ID acquisition unit 162 acquires the passenger ID “P012” stored in the ID storage unit 164 in association with the telephone number “XXX-XXX-1234” acquired by the short-range communication unit 172 (S100). The ID acquisition unit 162 passes the acquired passenger ID “P012” to the peripheral information display unit 120.

  The peripheral information display unit 120 is associated with the passenger ID “P012” delivered from the ID acquisition unit 162 and is stored in the basic attribute information 152 of the attribute storage unit 150 with the sex category “F” and the age “30”. The occupation category “J9” is extracted (S110). Also, the peripheral information display unit 120 stores the peripheral information type “associated with the peripheral information ID“ S0101 ”stored in the history attribute information 154 of the attribute storage unit 150 in association with the fellow passenger ID“ P012 ”. 13 "is extracted (same step). In this case, it is preferable that the peripheral information display unit 120 extracts the history attribute information 154 having a selected date and time within a predetermined period, for example, January, from the current date and time, from the history attribute information 154. This predetermined period may be set in advance in the peripheral information display unit 120 or may be set by an input from the user. Thereby, peripheral information can be acquired based on the latest action of the passenger.

  The current position acquisition unit 132 acquires the current position by receiving radio waves from the GPS satellite 14 (S120). The map display unit 110 reads a map from the map storage unit 140 based on the current position and the destination and displays the map on the display 106 (S130).

  The peripheral information display unit 120 generates peripheral information request data for requesting peripheral information based on the input destination, the attribute extracted in step S110, and the current position acquired in step S120 (S140). For example, as shown in FIG. 8, the peripheral information display unit 120 displays the current position “coordinates (X10, Y10)”, destination “coordinates (X11, Y11)”, gender category “F”, age “30”, occupation category Peripheral information request data including “J9”, peripheral information ID “S0101”, and peripheral information type “13” is generated. 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).

  The peripheral information acquisition unit 200 includes the current position “coordinates (X10, Y10)”, the destination “coordinates (X11, Y11)”, and the gender classification “F” included in the peripheral information request data received from the peripheral information display unit 120. The peripheral information ID is extracted from the peripheral information storage unit 210 using the age “30”, occupation classification “J9”, peripheral information ID “S0101”, and peripheral information type “13” as key items (S200). In this case, the peripheral information acquisition unit 200 may extract the peripheral information ID associated with the items that all match these key items from the peripheral information storage unit 210, and some of these key items may be extracted. Peripheral information IDs associated with items that match may be extracted from the peripheral information storage unit 210. It may be set in the peripheral information acquisition unit 200 in advance which item is extracted when it matches. In this case, if the location stored in the peripheral information storage unit 210 is within a predetermined area calculated from the current position and the destination that are key items, the peripheral information acquisition unit 200 sets the location as a key. It is determined that the current position and the destination that are items match.

  The peripheral information acquisition unit 200 determines whether or not at least one peripheral information ID has been extracted from the peripheral information storage unit 210 (S210). When it is determined in step S210 that at least one peripheral information ID has been extracted from the peripheral information storage unit 210 (S210: Yes), the peripheral information acquisition unit 200 responds with an icon image based on the extracted peripheral information ID. Is generated (S220). Specifically, when the peripheral information IDs “S0101” and “S0104” are extracted, the peripheral information acquisition unit 200 associates them with the peripheral information ID “S0101” and the peripheral information ID “S0101” as illustrated in FIG. The location “coordinates (X1, Y1)”, the icon image “restaurant A_emphasis.jpg” and the peripheral information type “13”, the peripheral information ID “S0104”, the peripheral information Response data including the location “coordinates (X4, Y4)”, the icon image “restaurant C_normal.jpg” and the peripheral information type “13” stored in the peripheral information storage unit 210 in association with the ID “S0104”. Generate. As described above, the peripheral information acquisition unit 200 performs two types of icons associated with the peripheral information ID for the peripheral information ID extracted using the peripheral information ID from the history attribute information 154 as a key item in step S200. Response data including an icon image that is an emphasized image is generated from the images. Thereby, since there is a possibility that the peripheral information that has stopped by in the past may stop again, it is possible to emphasize the peripheral information and make it easy for the user to recognize. The peripheral information acquisition unit 200 transmits the generated response data to the peripheral information temporary storage unit 142 of the peripheral information display device 10. Then, the peripheral information acquisition unit 200 stands by until reception of the next peripheral information request data.

  On the other hand, when it is determined in step S210 that the peripheral information acquisition unit 200 has not extracted at least one peripheral information ID from the peripheral information storage unit 210 (S210: No), the peripheral information acquisition unit 200 skips step S220. Until the next peripheral information request data is received.

  The peripheral information display unit 120 refers to the peripheral information temporary storage unit 142 to determine whether response data has been received (S150). If it is determined in step S150 that the response data has been received (S150: Yes), the peripheral information display unit 120 reads the icon image stored in the peripheral information temporary storage unit 142, and displays the read icon image as a map. The map is displayed on the display 106 so as to overlap the map displayed by the display unit 110 (S160). For example, as illustrated in FIG. 10, the peripheral information display unit 120 reads the location “coordinates (X1, Y1)” and the icon image “restaurant A_emphasized.jpg”, and displays the icon image “restaurant A_emphasized.jpg”. Is displayed on the display 106 based on the location “coordinates (X1, Y1)”, the location “coordinates (X4, Y4)” and the icon image “restaurant C_normal.jpg” are read out, and the icon image “restaurant” “C_normal.jpg” is displayed on the display 106 based on the location “coordinates (X4, Y4)”.

  As shown in FIG. 10, the peripheral information display unit 120 associates the spot name “Restaurant A” with the icon image “Restaurant C_Normal.jpg” in association with the icon image “Restaurant A_emphasis.jpg”. The spot name “Restaurant C” may be displayed in association therewith. In this case, in step S220, the peripheral information acquisition unit 200 generates response data including the spot name stored in the peripheral information storage unit 210 in association with the extracted peripheral information ID. The thick frame of the icon image “Restaurant A_emphasis.jpg” displayed with the spot name “Restaurant A” indicates that it is an emphasized image.

  On the other hand, if the peripheral information display unit 120 determines in step S150 that the response data has not been received by referring to the peripheral information temporary storage unit 142 (S150: No), the process skips step S160 and goes to step S170. move on.

  The peripheral information display unit 120 determines whether to end the display of the peripheral information (S170). 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 S170 that display of peripheral information is to be ended (S170: Yes), this flowchart ends. On the other hand, when the peripheral information display unit 120 determines in step S170 that the display of the peripheral information is not finished (S170: Yes), the process returns to step S120.

  In the display shown in FIG. 10, when the peripheral information display unit 120 receives an input for the icon image “restaurant C_normal.jpg” via the operation button of the operation panel 104, In association with the ID “P012”, the peripheral information ID “S0104” and the peripheral information type “13” stored in the peripheral information temporary storage unit 142 in association with the icon image “restaurant C_normal.jpg” Stored in the storage unit 150 as history attribute information 154. In this case, the peripheral information display unit 120 stores the date and time when the input is accepted as the selected date and time.

  In step S110, the peripheral information display unit 120 extracts the peripheral information ID and the peripheral information type associated with the selected date and time one month before and after the current date and time. It may be short or long.

  Further, in this flowchart, the surrounding information display unit 120 displays the surrounding information image icon on the map based on the passenger information, but based on the combination of the driver information and the passenger information, You may display the image icon of surrounding information on a map.

  FIG. 11 is a flowchart showing another example of the operation of the peripheral information display system 40.

  Steps S300 to S320 are the same as steps S100 to S120 shown in FIG. In step S325, the scheduled area calculation unit schedules the automatic vehicle to be located after a predetermined time based on the average speed calculated by the speed calculation unit and the current position acquired by the current position acquisition unit 132. The area is calculated (S325). 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 (X10, Y10) 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 (X10, Y10) that is 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 planned area calculation unit delivers information for specifying the calculated planned area to the map display unit 110 and the peripheral information display unit 120.

  Step S330 is the same as step S130 shown in FIG. In step S340, the peripheral information display unit 120 requests the peripheral information based on the input destination, the attribute extracted in step S310, and the information specifying the planned area acquired in step S325. Is generated (S340). 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 S400 to S420 are the same as steps S200 to S220 shown in FIG. Steps S350 and S360 are the same as steps S150 and S160 shown in FIG. In step S370, the peripheral information display unit 120 determines whether or not to end the display of the icon image (S370). When the peripheral information display unit 120 determines in step S370 that the display of the peripheral information is to be ended (S370: Yes), this flowchart ends.

  On the other hand, when it is determined in step S370 that the display of the peripheral information is not finished (S370: No), the peripheral information display unit 120 determines whether or not a predetermined time “60 minutes” has elapsed (S380). When it is determined in step S380 that the predetermined time “60 minutes” has elapsed (S380: Yes), the process returns to step S320. On the other hand, when it is determined in step S380 that the predetermined time “60 minutes” has not elapsed (S380: No), the process returns to step S370.
