  However, the opportunity for vehicles with the same type of in-vehicle device to meet is uncertain, and even if the vehicles encounter each other and exchange information held by each other, the in-vehicle device is owned depending on the location (region). Since there is a bias in the content of the information to be performed, there is a problem that new information cannot be acquired and the content of the information is limited.

  The present invention obtains a first vehicle group existence area with a relatively high holding ratio of predetermined information and a second vehicle group existence area with a relatively low holding ratio of information, and the second vehicle group existence The above problem is solved by causing the target vehicle predicted to move from the region to the first vehicle group existence region to acquire predetermined information from the in-vehicle device of another vehicle existing in the first vehicle group region.

  According to the present invention, even when there is a bias in the content of information held by the in-vehicle device for each region, the possibility of acquiring new content information is increased, so that information used by the user can be expanded. .

  The vehicle-side information exchange unit 220 includes an in-vehicle communication unit 221 and exchanges information with the external information processing server 100 and the in-vehicle devices 201, 202... 200 + N mounted on other vehicles. The in-vehicle communication unit 221 includes a mobile phone network, a wireless LAN such as UWB (Ultra Wide Band) and DSRC (Dedicated Short Range Communication), and an IEEE 802.11 system using an ISM (Industry Science Medical) band (2.4 GHz band). Using a wireless communication device in accordance with the wireless LAN standard, a wireless communication device in accordance with the Bluetooth standard, a communication device using terrestrial data broadcast waves, satellite broadcast waves, etc., exchange information with the in-vehicle device 201 and the information processing server 100 of other vehicles. Do. Note that the in-vehicle communication unit 221 may have a function of exchanging information with a traffic counter provided on the road.

  Information collected by the information collection unit 210 is accumulated in the data storage unit 240. The data storage unit 240 stores information (travel history 244, route information 245, travel state 246, road type 247) collected by the information collection unit 210, and a content list 241 that describes the content of the stored information. The information copy count 242 and the inter-vehicle communication count 243 are stored. As the data storage unit 240, a general storage medium such as a cache memory, main memory, HDD, CD, MD, DVD, optical disk, FDD, or the like is used.

  Further, the vehicle-side information transfer control unit 230 transmits predetermined information stored in the data storage unit 240 via the in-vehicle communication unit 221 according to an acquisition command or a transmission command acquired from the information processing server 100 described later. It sends out toward the in-vehicle device 201. Moreover, the vehicle side information transfer control part 230 acquires the information collected by the vehicle equipment 201,202 ... mounted in the other vehicle. The vehicle-side information transfer control unit 230 is configured by combining general operation circuits such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), and an FPGA (Field Programmable Gate Array). Is done.

  Next, the information processing server 100 will be described. As shown in FIG. 1, the information processing server 100 includes a server-side information transfer unit 10, an information content analysis unit 20, a communication frequency analysis unit 30, a region setting unit 40, a target vehicle prediction unit 50, and an information transfer. A management unit 60, an aggregation memory 70, and map information 80 are included. An information content analysis unit 20 that controls information processing, a communication frequency analysis unit 30, a region setting unit 40, a target vehicle prediction unit 50, and an information transfer management unit 60 include a CPU (Central Processing Unit) and an MPU (Micro Processing). Unit), DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), and other general operation circuits are combined. The aggregate memory 70 and the map information 80 use accessible storage media such as a main memory, HDD, CD, MD, DVD, optical disk, and FDD.

  As shown in FIGS. 1 and 2, the server-side information transfer unit 10 includes a server communication unit 11, and includes a content list 241, an information copy count 242, an inter-vehicle communication count 243, an identifier of the in-vehicle device 200 from the in-vehicle device 200. Get information including. The server communication unit 11 is a mobile phone network for exchanging information with the in-vehicle communication unit 221, a wireless LAN such as UWB (Ultra Wide Band) and DSRC (Dedicated Short Range Communication), terrestrial data broadcast wave, satellite broadcast wave. A communication device using such as can be used.

  Moreover, the information content analysis part 20 acquires the content list 241 which each vehicle-mounted apparatus 200 memorize | stores, and analyzes the content of the information which the vehicle-mounted apparatus 200 grade | etc., Holds based on the content list. In the content list 241, the information stored in the in-vehicle device 200 is detected for each type of information (for example, information category such as travel history, route information, travel state, road type, etc.), for each region where the information is detected. It is categorized and described by time. And the information content analysis part 20 analyzes whether the information of the predetermined content is contained in the content list 241 of the vehicle-mounted device 200. That is, the information content analysis unit 20 determines whether or not the in-vehicle device 200 has information on certain contents (for example, the traveling speed of a predetermined road, the time required for passing a predetermined road link, etc.).

  In addition, the information content analysis unit 20 acquires the information copy count 242 from the in-vehicle device 200, and determines whether the in-vehicle device 200 has information with a predetermined content based on the information copy count 242. This is because it can be determined that the greater the number of information copies 242, the higher the possibility of acquiring information from the in-vehicle device 201 or the information processing server 100 of another vehicle and holding information of a predetermined content.

  Further, the communication frequency analysis unit 30 analyzes the communication frequency with other in-vehicle devices 201 and the like based on information acquired from each in-vehicle device 200 via the in-vehicle communication unit 221 and the server communication unit 11. The communication frequency analysis unit 30 obtains the communication frequency of the in-vehicle device 200 based on the number of communication per unit time of the in-vehicle communication unit 221.

  Then, the region setting unit 40 determines whether the first vehicle group region and the second vehicle group region are based on the “analysis result of the information content” by the information content analysis unit 20 and / or the “communication frequency” by the communication frequency analysis unit 30. And set. FIG. 2 is a diagram illustrating an example of a vehicle group region set based on “analysis result of information content” and / or “communication frequency”.

  First, based on the analysis result of the information content of the information content analysis unit 20, the region setting unit 40 has a relatively high proportion of in-vehicle devices 200 that hold information of a certain content A (information of a predetermined content). And a second vehicle group region in which the in-vehicle devices 201 having information of certain content A (information of predetermined content) are present at a relatively low rate. The first vehicle group region and the second vehicle group region are preferably close to each other.

  For example, the region setting unit 40 sets an arbitrary first vehicle group region, and a region in which “the ratio of the in-vehicle device 200 that holds information of a predetermined content” is lower than that in the first vehicle group region Is set as the second vehicle group region. In addition, arbitrary 1st vehicle group area | regions are good also as an area | region where "the ratio in which the vehicle-mounted apparatus 200 which holds the information of a predetermined content exists" is more than a predetermined threshold value.

  In addition, the region setting unit 40 sets a region in which “the ratio of the in-vehicle device 200 having information of a predetermined content exists” higher than a preset threshold as the first vehicle group region, A region where “the ratio of the in-vehicle device 200 that holds information” is less than a preset threshold is set as the second vehicle group region.

  Incidentally, the “predetermined information” for which it is examined whether or not it is held in the area setting unit 40 can be arbitrarily defined. As described above, “predetermined content information” may be defined as content of predetermined information such as “travel speed on a certain road (traffic congestion information)” in which the target area is limited. Content with a limited target time such as “traveling speed of a certain road from 8 am to 10 am (traffic congestion information)” may be defined as the content of the predetermined information.

  Similarly, the proportion of the in-vehicle device 200 that holds information of a predetermined content based on the number of times of information copy 242 from the viewpoint that the more information is copied, the higher the possibility that information of the predetermined content is acquired. Can be judged.

  For example, the region setting unit 40 sets an arbitrary first vehicle group region, and “the ratio of the in-vehicle device 200 in which the number of times of information copying 242 is higher than a preset threshold” is set in the first vehicle group region. A lower region is set as the second vehicle group region. Note that the arbitrary first vehicle group region may be a region in which “the ratio of the in-vehicle device 200 in which the number of times of information copying 242 is higher than a preset threshold value” is a predetermined threshold value or more.

  In addition, the area setting unit 40 sets, as the first vehicle group area, an area in which “the ratio of the in-vehicle device 200 in which the number of times of information copying 242 is higher than a preset threshold” is higher than a preset threshold, An area where “the ratio of the in-vehicle device 200 in which the number of times of information copying 242 is higher than a preset threshold value” is less than a preset threshold value can be set as the second vehicle group area.

  In addition, the definition of “the ratio of in-vehicle devices 200” can be arbitrarily set. In this example, the number of in-vehicle devices 200 in which information of predetermined contents is described in the acquired content list 241 is indicated. The value is divided by the total number of in-vehicle devices 200 that exchange information with the information processing server 100. Furthermore, the “ratio where the in-vehicle device 200 exists”, the “ratio where the in-vehicle device 200 exists”, the number of the in-vehicle devices 200 in which the information of the predetermined content is described in the acquired content list 241, and the content list 241. Can be defined as a value divided by the total number of in-vehicle devices 200 that have received.

  Next, the target vehicle prediction unit 50 will be described. The target vehicle prediction unit 50 identifies a vehicle that moves between the first vehicle group region and the second vehicle group region that are set in advance. The target vehicle prediction unit 50 sets the target vehicle as the vehicle A predicted to move from the area 2 corresponding to the second vehicle group region to the area 1 corresponding to the first vehicle group region shown in FIG. Similarly, the vehicle B predicted to move from the area 1 corresponding to the first vehicle group area to the area 2 corresponding to the second vehicle group area shown in FIG.

  The target vehicle prediction unit 50 of this example refers to the accessible map information 80 based on the position of the first vehicle group region and the position of the second vehicle group region, and the first vehicle group region and the second vehicle group region A target vehicle that is predicted to move between is identified.

  Specifically, the target vehicle prediction unit 50 includes travel information including any one or more of a travel history, route information, a guide route, a traveling direction, a road type, and traffic information of a vehicle on which the in-vehicle device 200 is mounted, Based on the position of the first vehicle group area and the position of the second vehicle group area, the target vehicle is predicted with reference to the accessible map information 80.

  Based on FIG. 4, an example of a technique for predicting a vehicle moving from area 1 corresponding to the first vehicle group region to area 2 corresponding to the second vehicle group region will be described.

  The vehicle B shown in FIG. 4 moves from the current position in the area 1 to the destination G. The routes that can be used when moving from the current position of the vehicle B to the destination G are the three routes 1 to 3. When vehicle B uses route 1 or route 2, since vehicle B passes through area 2, it can be predicted that vehicle B will move from area 1 to area 2.

  A prediction method in this case will be described. As a first method, the target vehicle prediction unit 50 predicts the target vehicle based on the travel history of the vehicle B. For example, in the travel history, when the number of times vehicle B travels in area 2 is higher than a predetermined threshold, it is predicted that vehicle B will use route 1 or route 2 passing through area 2, and as a result, vehicle B Expect to move from 1 to area 2. As a second method, the target vehicle prediction unit 50 predicts the target vehicle based on the route information presented by the navigation device 400 mounted on the vehicle B based on the route information. For example, when the navigation device 400 mounted on the vehicle calculates a route passing through the area 1 or 2 as the guidance route, the vehicle is predicted as a target vehicle that moves to the area 1 or the area 2. Specifically, when the navigation device 400 uses the route 1 or the route 2 as a guidance route, the vehicle B is predicted to move from the area 1 to the area 2. As a third method, the target vehicle prediction unit 50 predicts the target vehicle based on the traveling direction of the vehicle B (detected by the navigation device 400). For example, when the traveling direction of the vehicle B belongs to the direction of the range A toward the area 2 based on the current position, that is, when the vehicle B travels toward the area 2, the vehicle B moves from the area 1 to the area 2. I predict that. Furthermore, as a fourth method, the target vehicle prediction unit 50 predicts the target vehicle based on the road type. For example, when the road on which the vehicle B travels is an arterial road, an expressway, and a toll road, and the road passes through the area 2, the vehicle B uses the traveling arterial road as it is to move from the area 1 to the area 2. Expect to move. This is because the vehicle B traveling on the main road is considered to continue to use the main road that is easy to travel. In addition, as a fifth method, the target vehicle prediction unit 50 predicts the target vehicle based on the traffic jam information. For example, when the congestion levels of the routes 1 to 3 reaching the destination G are different and the congestion level of the route 1 or 2 is relatively mild (no congestion), the vehicle B uses the route 1 or 2 that is not congested. It is predicted to move from area 1 to area 2 by using it.

  The target vehicle prediction unit 50 sends a communication ID for identifying the predicted target vehicle, a vehicle ID, and other identifiers to the information transfer management unit 60.

  Next, the information transfer management unit 60 will be described. The information transfer management unit 60 includes an acquisition command generation unit 61, a transmission command generation unit 62, and a command unit 63, and causes the target vehicle predicted by the target vehicle prediction unit 50 to execute acquisition or transmission of information.

  The acquisition command generation unit 61 moves the target vehicle from the second vehicle group area (area 2) having a low information holding ratio with a predetermined content to the first vehicle group area (area 1) having a high information holding ratio with a predetermined content. Generates an acquisition command for causing the target vehicle to acquire information of a predetermined content from an in-vehicle device of another vehicle existing in the first vehicle group region.

  As illustrated in FIG. 5, the target vehicle prediction unit 50 obtains the predetermined content information 3 from the area 2 in which the vehicle-mounted device 200 having the predetermined content information 3 is present at a relatively low rate. When it is predicted that the in-vehicle device 200 that is owned will move to the area 1 that exists at a relatively high rate, the acquisition command generation unit 61 may indicate that “the target vehicle moving to the area 1 An “acquisition instruction for acquiring information 3 from the in-vehicle device 201” is generated. Then, the command unit 63 sends the generated acquisition command to the vehicle A via the server communication unit 11.

  The vehicle-side information transfer control unit 230 of the in-vehicle device 200 acquires the information 3 that is unlikely to be held by the vehicle-side information transmission / reception control unit 230 from the information processing server 100 from the in-vehicle device 201 of the other vehicle.

  In addition, the vehicle side information transfer control part 230 of the vehicle-mounted apparatus 200 has the content list comparison part 231, and can also specify the information which the own vehicle does not hold, and can acquire it from another vehicle. In this case, the content list comparison unit 231 compares the content list of the other vehicle with the content list of the own vehicle, specifies information that is not owned by the own vehicle and is held by the other vehicle, and uses the information as the other vehicle. Get from. Note that the vehicle-side information transfer control unit 230 can also acquire predetermined information from the information processing server 100.

  As described above, the vehicle A having a low possibility of holding the information 3 moves to the area 1 having a high possibility of holding the information 3 and acquires the information 3. In this way, by increasing the possibility of causing the vehicle A to acquire new information 3 (information with predetermined contents), it is possible to expand the information of the own vehicle, and as a result, information 3 (information with predetermined contents) is shared. Area to be expanded.

  Further, as shown in FIG. 6, the target vehicle prediction unit 50 causes the vehicle B to receive the predetermined content information from the area 1 where the in-vehicle devices 200 having the predetermined content information 3 exist at a relatively high rate. 3 is predicted to move to the area 2 where the in-vehicle device 200 having 3 is present at a relatively low rate, the sending command generation unit 61 indicates that “the target vehicle B moving to the area 2 exists in the area 2. A “sending command for sending information 3” to the in-vehicle device 201 of the other vehicle is generated. Then, the command unit 63 sends the generated acquisition command to the vehicle B via the server communication unit 11.

  The vehicle-side information transfer control unit 230 of the vehicle-mounted device 200 of the vehicle B has the information 3 that is highly likely to be stored in the vehicle-mounted device 200 in accordance with the transmission command received from the information processing server 100. It is sent to the in-vehicle device 201 of another vehicle that is unlikely to be present.

  In this case, the vehicle-side information transfer control unit 230 of the in-vehicle device 200 can specify information that is not held by the other vehicle and send it to the other vehicle. The content list comparison unit 231 of the vehicle-side information transfer control unit 230 compares the content list of the other vehicle with the content list of the own vehicle, specifies information that is not owned by the other vehicle and is owned by the own vehicle, The information is sent to other vehicles. Note that the vehicle-side information transfer control unit 230 can also send predetermined information to the information processing server 100.

  Thus, the vehicle B having a high possibility of holding the information 3 transmits the information 3 when moving to the area 2 having a low possibility of holding the information 3. In this way, the information of other vehicles is expanded by increasing the possibility that other vehicles existing in the area 2 that is unlikely to hold the information 3 (information of predetermined contents) will acquire the new information 3. As a result, the area where information 3 (information of predetermined contents) is shared can be expanded.

  Prior to this process, as shown in FIG. 6, the acquisition command generation unit 61 determines that the target vehicle B predicted to move from area 1 (first vehicle group region) to area 2 (second vehicle group region) When the information 3 with the predetermined content is not held, an acquisition command for causing the target vehicle B existing in the area 1 to acquire the information 3 with the predetermined content from the in-vehicle device 202 of the other vehicle existing in the area 1 is generated, and the server communication It is sent to the vehicle B via the part 11.

  The vehicle-side information transmission / reception control unit 230 of the vehicle-mounted device 200 of the vehicle B is highly likely to have the information 3 in the information 3 that the vehicle-mounted device 200 does not have in accordance with the acquisition command received from the information processing server 100. Acquired from the in-vehicle device 201 of another vehicle existing in area 1.

  In this way, since the vehicle B that moves to the area 2 that has a low possibility of holding the information 3 always has the information 3 and sends the information 3 when the vehicle B moves to the area 2, the vehicle B Information 3 can always be transmitted when moving to 2. For this reason, the vehicle B can reliably provide the new information 3 to other vehicles existing in the area 2 where the possibility of holding the information 3 is low. As a result, the area where information 3 (information with predetermined contents) can be shared can be expanded.

  Next, the control procedure of the information processing system 1000 will be described based on the flowcharts of FIGS.

  As shown in FIG. 7, first, the information collection unit 210 of the in-vehicle device 200 collects information detected by the vehicle controller 300 and the navigation device 400 (S101). The collected vehicle speed information, position information, link transit time and other vehicle-side information, and other information are accumulated in the data storage unit 240 (S102). This collection and accumulation of vehicle-side information is repeated at predetermined intervals.

  The vehicle-side information transfer control unit 230 of the in-vehicle device 200 receives information from the in-vehicle device 201 of another vehicle in the content list 241 in which the content of the information held by the in-vehicle device 200 is described and / or the data storage unit 240 of the in-vehicle device 200. Is sent to the information processing server 100 (S103).

  The information processing server 100 receives the information on each vehicle side via the server side transmitting / receiving unit 10 and accumulates the information in the aggregation memory 70 (S201).

  The information content analysis unit 20 of the information processing server 100 analyzes the content of information based on the received content list and / or information copy count (S202).

  Further, the vehicle-side information transfer control unit 230 of the in-vehicle device 200 sends the number of inter-vehicle communication 243 related to the communication frequency of the in-vehicle device 200 to the information processing server 100 (S104). The communication frequency analysis unit 30 of the information processing server 100 analyzes the communication frequency of the in-vehicle device 200 based on the received inter-vehicle communication count 243 (S203).

  The region setting unit 40 includes a first vehicle group region in which the frequency of communication with other in-vehicle devices is equal to or higher than a predetermined threshold and the in-vehicle devices 200 having information of a predetermined content are present at a relatively high rate. Then, a search is made for a second vehicle group area where the frequency of communication with other in-vehicle devices is equal to or higher than a predetermined threshold and the in-vehicle devices 200 having information of predetermined contents are present at a relatively low rate (S204). In this processing example, when setting the vehicle group area, the analysis result of the information content held by the in-vehicle device 200 and the communication frequency between the in-vehicle devices 200 are considered, but only based on the analysis result of the information content. Thus, the first vehicle group area where the in-vehicle devices 200 having information of predetermined contents exist at a relatively high rate and the in-vehicle devices 00 having information of predetermined contents exist at a relatively low rate. Two vehicle group areas may be set.

  If there is no such area as a result of the search in S204 (N in S204), the process returns to S201, and if there is such an area (Y in S204), the process proceeds to S205.

  Then, the searched areas are set as a first vehicle group area and a second vehicle group area that are targets of information exchange management (S205).

  In this way, by setting two or more areas based on the analysis result of the contents of information held by the in-vehicle device 200, it is possible to observe the bias of the contents of the information held for each area. In addition, by setting two or more areas in consideration of the communication frequency of the in-vehicle device 200, it is possible to set areas where the communication frequency is equal to or higher than a predetermined threshold, and information on areas where information is exchanged frequently. Can give and receive management instructions.

  When the first vehicle group area and the second vehicle group area are set in S204, at least the in-vehicle devices 201, 202,... Existing in the areas are travel history 244, route information 245, travel state 246, road type. 247 Other travel information is sent to the information processing server 100 (S105). The target vehicle prediction unit 50 on the information processing server 100 side acquires the travel information via the server communication unit 11 (S206).

  Subsequently, the target vehicle prediction unit 50 accesses the map information 70 and refers to the map information to predict a target vehicle that moves from the second vehicle group region to the first vehicle group region (S208).

  The information transfer management unit 60 generates an information transfer command (information acquisition command or information transmission command) for the predicted target vehicle (S209).

  A specific processing example of S209 will be described based on the flowchart of FIG. As shown in FIG. 8, first, the target vehicle is predicted to move from the second vehicle group region having a low probability of holding information of a predetermined content to the first vehicle group region having a high probability of holding information of a predetermined content. If yes (Y in S301), the process proceeds to S302. And the acquisition command production | generation part 61 produces | generates the acquisition command which makes the object vehicle which moved to the 1st vehicle group area | region acquire the information of predetermined content from the vehicle which exists in a 1st vehicle group area | region. The generated information exchange command is sent to the in-vehicle device 200 via the server communication unit 11 (S210).

  Returning to S301, the vehicle moving from the second vehicle group region to the first vehicle group region is not predicted, but the predetermined content information is retained from the first vehicle group region having a high probability of retaining the predetermined content information. If it is predicted that the target vehicle will move to the second vehicle group region with a low probability (Y in S306), the process proceeds to S307, and if not, the process ends.

  In S307, the information transfer management unit 60 further determines whether or not the target vehicle has information of a predetermined content (S307). If the target vehicle does not have information with a predetermined content, the acquisition command generation unit 61 issues a command that causes the target vehicle to acquire information with a predetermined content from an in-vehicle device of another vehicle existing in the first vehicle group region. Generate and send out. The vehicle-side information transmission / reception control unit 230 of the target vehicle existing in the first vehicle group area acquires the predetermined content information from the in-vehicle device of the other vehicle that also exists in the first vehicle group area in accordance with the received acquisition command. .

  When the target vehicle has information of a predetermined content in advance (Y in S307), or when information of the predetermined content is acquired from the in-vehicle device 200 of another vehicle (S308), the sending command generation unit 62 sends the second vehicle A sending command for causing the target vehicle moving to the group area to send information of a predetermined content to the in-vehicle device of another vehicle existing in the second car group area is generated (S309). The generated information exchange command is sent to the in-vehicle device 200 via the server communication unit 11 (S210).

  Returning to S210 in FIG. 7, the vehicle-side information transfer control unit 230 of the in-vehicle device 200 that has received the information transfer command executes the information transfer command (S106).

  Since the information processing server 100 of this embodiment operates as described above, the following effects can be obtained.

  In the present embodiment, the in-vehicle device 200 that has the predetermined content information is relatively high from the second vehicle group area where the in-vehicle device 200 that has the predetermined content information exists at a relatively low rate. Predict the target vehicle that moves to the first vehicle group area, and acquire information of predetermined contents from the in-vehicle device 200 of the other vehicle that exists in the first vehicle group area to the target vehicle that moves to the first vehicle group area. Let For this reason, the possibility that the in-vehicle device 200 having a low probability of holding the predetermined information acquires the predetermined information can be increased.

  In the present embodiment, the in-vehicle device 200 that holds the predetermined content information is relatively low from the first vehicle group area where the in-vehicle device 200 that holds the predetermined content information exists at a relatively high rate. Predict the target vehicle that moves to the second vehicle group area that exists in proportion, and the target vehicle that moves to the second vehicle group area has a predetermined content with respect to the in-vehicle device 201 of the other vehicle that exists in the second vehicle group area. Send the information. For this reason, the vehicle-mounted device 200 having a high probability of holding the predetermined information is transmitted with the predetermined content information, and the vehicle-mounted device 200 existing in the second vehicle group region having the low probability of holding the predetermined information is Can increase the chances of getting.

  Furthermore, when the target vehicle predicted to move from the first vehicle group region to the second vehicle group region does not have the predetermined content information, the target vehicle is previously acquired the predetermined content information, Since the information is sent to the in-vehicle device 201 in the second vehicle group area, information of a predetermined content can be reliably provided to the in-vehicle device 201 in the second vehicle group area.

  In this way, the in-vehicle devices possessed by causing the in-vehicle devices 200, 201... Existing in the respective vehicle group existence areas having different holding ratios of predetermined information to exchange (acquire and send) the information owned by each. Even if there is a bias in the content of information for each region, the possibility of acquiring new information can be increased, so that the information held by each in-vehicle device 200 can be expanded and predetermined information is held The presence area of the in-vehicle device 200 can be expanded.

  In addition, when setting the vehicle group area, in addition to the analysis result of the information content owned by the in-vehicle device 200, the communication frequency of the in-vehicle device 200 is added on the condition that the communication frequency is equal to or higher than a predetermined threshold. Since the in-vehicle device 200 having a relatively high value can be an object of information exchange, information of a predetermined content can be reliably exchanged.

  Furthermore, the first vehicle group region and the second vehicle group region are moved by predicting the target vehicle with reference to the map information based on the position of the first vehicle group region and the position of the second vehicle group region. Since the target vehicle can be predicted in consideration of the route, it is possible to predict a target vehicle that is highly likely to move between the two regions.

  In particular, by considering the travel information including any one or more of the travel history, route information, travel direction, road type, and traffic information of the vehicle on which the in-vehicle device 200 is mounted, the user's past travel experience, The target vehicle can be predicted in consideration of the route provided by the navigation device 400 according to the designated destination, the actual moving direction of the vehicle, the road environment, and the possibility of route change for avoiding traffic jams. It is possible to more accurately predict a target vehicle that is likely to move between areas.

  Moreover, the information processing method using the vehicle-mounted device 200 has the above-described operations and effects.
