The posted traffic information is posted from a terminal that can be connected to the network 3 such as a mobile phone or a personal computer in addition to the navigation device 20. The posted traffic information includes traffic information such as an accident or traffic jam at a spot on the map, facility information regarding a spot facility on the map, and the like. It is assumed that the traffic information of the present embodiment includes regional information such as fireworks display, World Expo, and cherry blossom information. Further, position information indicating the position of the information is added to the posted traffic information.

By the way, if all the posted traffic information acquired from the server 10 is displayed on the map, old posted traffic information different from the current status may be displayed, or if there is a lot of posted traffic information, the map may be difficult to see.
Therefore, in the present embodiment, the control unit 33 executes a posted traffic information erasing process for erasing the posted traffic information and functions as a display erasing unit.

FIG. 2 is a flowchart showing the posted traffic information erasing process.
If operation which starts an information sharing application is performed, the control part 33 will display a contribution traffic information display screen, and will wait until update of contribution traffic information (step S1). Here, the posted traffic information display screen is shown in FIG. The posted traffic information display screen 40 is a screen for displaying posted traffic information on a map and posting posted traffic information. The posted traffic information display screen 40 includes a map 41, a current position 42, An update button 43 and a posting button 44 are displayed. In the present embodiment, the posted traffic information is updated by operating the update button 43. The posted traffic information may be automatically updated every predetermined time or every predetermined moving distance of the vehicle 2.

  When the update button 43 is operated, for example, when the posted traffic information is updated (step S1: Yes), the control unit 33 transmits the posted traffic information display area to the server 10 (step S2). The posted traffic information having the location information of the spot is received from the server 10 (step S3). Here, the display area of the posted traffic information may be the same as the display area of the map, or may be within a predetermined distance from the current position. Next, the control unit 33 determines whether the received posted traffic information includes facility information (step S4).

  When the posted traffic information does not include the facility information (step S4: No), the control unit 33 determines whether the traffic information of the posted traffic information has been eliminated (step S5). For example, the control unit 33 determines that the traffic information of the posted traffic information has not been resolved if the VICS data including the location information of the posted traffic information has not been received. When the VICS data having the location information of the posted traffic information is received, the control unit 33 compares the traffic information of the posted traffic information with the traffic information of the VICS data having the location information of the posted traffic information. If (for example, accident, traffic jam, regional information, etc.) are different, it is determined that the traffic information of the posted traffic information has not been eliminated. Further, when the posted traffic information and the traffic information type of the VICS data are the same, the control unit 33 cancels the traffic information of the posted traffic information if the posted time of the posted traffic information is before the reception time of the VICS data. It is determined that On the other hand, if the posting time of the posted traffic information is later than the reception time of the VICS data, the control unit 33 determines that the traffic information of the posted traffic information has not been eliminated. When the traffic information includes regional information, the control unit 33 determines that the traffic information of the posted traffic information has been resolved if, for example, a period (for example, a holding period) included in the regional information has ended. . On the other hand, the control unit 33 determines that the traffic information of the posted traffic information can be eliminated if the period included in the area information has not ended.

When the traffic information of the posted traffic information has been eliminated (step S5: Yes), the control unit 33 deletes the received posted traffic information including the eliminated traffic information (step S6). In this way, since the traffic state at the spot where the posted traffic information is posted is determined based on the VICS data, and the posted traffic information is deleted according to the determination result, the old posted traffic information different from the current traffic state Can be deleted from the map.
And the control part 33 displays the contribution traffic information which was not erase | eliminated by step 6 on a contribution traffic information display screen (step S7), and returns a process to step S1. When the posted traffic information is displayed on the posted traffic information display screen, the control unit 33 pops up the posted traffic information through the small window 45 as shown in FIG.
When the traffic information of the posted traffic information has not been eliminated (step S5: No), the control unit 33 shifts the process to step S7.

When the posted traffic information includes facility information (step S4: Yes), the control unit 33 determines whether or not the facility indicated by the facility information of the posted traffic information is in the corresponding spot on the map (step S8).
When the facility indicated by the facility information of the posted traffic information is not present at the corresponding spot on the map (step S8: No), the control unit 33 shifts the process to step S7.
When the facility indicated by the facility information of the posted traffic information is at the corresponding spot on the map (step S8: Yes), the control unit 33 deletes the received posted traffic information including the facility information at the corresponding spot on the map. (Step S6), and the process proceeds to Step S7.

  For example, as shown in FIG. 5A, when posted traffic information is posted regarding a facility (for example, a charging spot) that is not reflected in the map 41, the posted posted traffic information pops up through a small window 45. Is displayed. After that, as shown in FIG. 5B, when the map data is updated and the facility 46 (charging spot) indicated by the posted traffic information is reflected on the map 41, the posted traffic information regarding the facility 46 is deleted. It will be. In this way, since the facility information is deleted when the facility indicated by the facility information of the posted traffic information is in the corresponding spot on the map, it is possible to prevent duplicate information from being displayed on the map and to make the map easier to see. .

Next, a posting process for posting posted traffic information from the navigation device 20 will be described.
FIG. 6 is a flowchart showing posting processing of posted traffic information.
When the posting button 44 shown in FIG. 3 is operated, the control unit 33 executes posting processing of posted traffic information and functions as a posting unit.
First, for example, the control unit 33 displays a list of types such as accident, traffic jam, area information, and facility information on the posted traffic information display screen, and accepts selection of a category of posted traffic information (step S11).

  Next, the control unit 33 accepts input of position information (step S12). The position information is input, for example, when the user selects a spot on the map on the posted traffic information display screen. Next, the control part 33 receives the input of a contribution text (step S13). At this time, for example, a list of fixed form sentences stored in advance in the storage unit 26 may be displayed on the display unit 24, and the fixed form sentence selected via the operation unit 25 may be used as the posted sentence. In addition, a character string received via the operation unit 25 by displaying a keyboard on the display unit 24 may be used as a posted sentence. Furthermore, the user's voice data received from the voice input unit 27 may be used as a posted sentence by reproducing or displaying a guide voice prompting the utterance, or converting the received voice data into characters and using the characters as a posted sentence. Also good.

And the control part 33 transmits the display area of contribution traffic information to the server 10 (step S14), and receives the contribution traffic information which has the positional information on the spot in a display area from the server 10 (step S15). Next, the control unit 33 determines whether or not the input posted text includes the same spot and the same type of information as the received posted traffic information (step S16).
When the posted text does not include the same spot and the same type of information as the received posted traffic information (step S16: No), the control unit 33 posts the posted text as posted traffic information (step S17), and processing Exit.

When the posted text includes the same spot and the same type of information as the received posted traffic information (step S16: Yes), the control unit 33 determines whether the received posted traffic information is its own post (step). S18).
When the received posted traffic information is not its own post (step S18: No), the control unit 33 deletes the posted text and ends the process. In this way, posting traffic information including the same spot as the posted traffic information distributed by the server 10 and posted traffic information including the same type of information is prohibited, so that the posted traffic information with overlapping contents regarding one spot is posted. Can be prevented.

  When the received posted traffic information is its own post (step S18: Yes), the control unit 33 deletes the posted traffic information including the same spot and the same type of information as the posted text from the posted traffic information database of the server 10. (Step S19), the process proceeds to Step S17, and the posted text is posted as posted traffic information. For example, as shown in FIG. 4, when the posted traffic information “It is an accident” is posted from the navigation device 20 regarding the spot A on the map 41, the navigation device 20 then says “It is an accident”. After the posted traffic information is deleted from the server 10, as shown in FIG. As described above, since only the posted traffic information posted from its own device can post the same type of traffic information for the same spot, the latest information can be posted. Moreover, since the old posted traffic information is deleted, it is possible to prevent the posted traffic information having the same content regarding one spot from being posted.

  As described above, according to the present embodiment, the traffic state at the spot where the posted traffic information is posted is determined based on the VICS data, and the posted traffic information is determined from the map according to the determination result. It was set as the structure erase | eliminated. With this configuration, it is possible to quickly delete old posted traffic information that is inconsistent with the current traffic state from the map.

  Moreover, according to this Embodiment, the navigation apparatus 20 is provided with the control part 33 which contributes contribution traffic information to the server 10, and contains the same spot and the same kind of traffic information as the contribution traffic information which the server 10 delivers. Posting traffic information is prohibited from posting. With this configuration, it is possible to prevent posted traffic information with overlapping traffic information regarding one spot from being posted.

  In addition, according to the present embodiment, the navigation device 20 can post the same type of traffic information for the same spot only in the posted traffic information distributed from the server 10 among the posted traffic information distributed by the server 10. It was set as the structure to do. With this configuration, the latest information can be posted from the own device regarding the same spot and the same type of traffic information.

  Further, according to the present embodiment, the posted traffic information includes the facility information regarding the facility of the spot on the map, and the navigation device 20 does not have the facility indicated by the facility information of the posted traffic information at the corresponding spot on the map. The facility information is displayed on the condition. With this configuration, when the facility indicated by the facility information of the posted traffic information is in the corresponding spot on the map, the facility information overlapping with the facility on the map can be deleted from the map.

However, the above embodiment is an aspect of the present invention, and it is needless to say that the embodiment can be appropriately changed without departing from the gist of the present invention.
For example, in the above embodiment, the posted traffic information is deleted regardless of the posting source (for example, navigation device, mobile phone, personal computer) in step S6 of FIG. 2, but the posting source is limited. Only posted traffic information posted from the device may be deleted.

  In the above embodiment, traffic information around the current position is acquired by receiving VICS data (distributed traffic information) distributed by the VICS center. However, the traffic information providing system (not limited to VICS) ( Distribution traffic information around the current position may be acquired via AMIS) or the Internet.

  In the above embodiment, the posted traffic information is displayed in a pop-up on the map through a small window, but the display format of the posted traffic information is not limited to this. For example, as shown in FIG. 8, the posted traffic information display screen 40 is divided into a map screen 40A and a posted traffic information screen 40B, a user-specific icon 47 is displayed on the map screen 40A, and information on the posted traffic information screen 40B is displayed. The display unit 48 may display the icon 47 and posted traffic information posted by the user indicated by the icon 47. Here, when the number of posted traffic information to be displayed on the information display unit 48 is large, or when the content of the posted traffic information is large, the information display unit 48 may be configured to be scrollable. Reference numerals 49A to 49D are type selection buttons for selecting the type of posted traffic information. By operating the type selection buttons 49A to 49D, the types of posts corresponding to the operated type selection buttons 49A to 49D are displayed. Traffic information is displayed on the information display unit 48.

  The present invention is not limited to a navigation device mounted on a vehicle, but can be widely applied to a navigation device mounted on a vehicle such as an arbitrary ship or aircraft, and is not limited to a vehicle-mounted type. You can also
