  FIG. 4 is a block diagram showing a schematic configuration of the server device 4 shown in FIG. The configuration shown in FIG. 4 is simplified for explaining the present invention, and it is assumed that the components mounted on the normal server device are provided.

  The server device 4 includes a control unit 41 that controls the entire device, a communication control unit 42 that communicates with the mobile terminal 1 and the in-vehicle device 3 via the mobile communication network 2, and an index used for risk determination A point database (DB) 43 in which points as values are registered, a pedestrian information database (DB) 44 in which information (risk level information) indicating the degree of danger of a pedestrian carrying the mobile terminal 1 is registered, and in-vehicle A vehicle information database (DB) 45 in which information (risk level information) indicating the risk level of the vehicle on which the device 3 is mounted is registered, and an application control unit 46 that activates various applications mounted on the device or downloaded.

Then, points such as “−1”, “−1”, “−1”, “−2” and “+1” are registered in the point information 53 corresponding to the action information 52. While “traffic roads”, “road crossing without pausing”, “acceleration and crossing road” and “ignore signal” are registered as dangerous actions, deduction points (-(minus) points) are registered. “Passing along the road edge at a constant speed” is registered with an additional point (+ (plus) point) as a safe action. Also, the reason for the greater deduction points for “ignoring traffic light” than for “passing through the road for vehicles” is because the degree of risk is higher than for “ignoring traffic signal” for “passing for traffic roads”, etc. .

The reason why “Ignore signal” has a larger deduction point compared to “Exceeding legal speed (small)” is because “Ignoring signal” is more dangerous than “Exceeding legal speed (small)”. . Note that the management items and management methods in the management table shown in FIG. 5 are not limited to this, and can be implemented with appropriate changes.

  The pedestrian information DB 44 is a database in which risk information of pedestrians who carry the mobile terminal 1 is registered.

In the management table shown in FIG. 7, the identification information 71 of the in-vehicle device 3, point information 72 indicating the degree of danger of the in-vehicle device 3 (vehicle), the risk rank information 73 corresponding to the point information 72, and the in-vehicle device 3 (vehicle). Position information 74 is registered. 7 shows the case where the telephone number assigned to the in-vehicle device 3 is used for the identification information 71, the identification information 71 is not limited to this, and can be changed as appropriate. . For example, the in-vehicle device 3 or the vehicle serial number may be used.

  In the point information 72, points “0” to “30” are registered, and “15” points are registered at the beginning of provision of this service. Then, from the “15” points, points added or subtracted according to the operation information received from the in-vehicle device 3 are registered. The risk rank information 73 is determined according to the current point information 72. Here, the point “21-30” is set as a rank “A” indicating that the degree of risk is low, the point “11-20” is set as a rank “B” indicating that the degree of risk is normal, and the point “0-10” is set.

  The application control unit 46 activates a risk management application installed in the device or downloaded. The risk management application for the server device 4 determines the pedestrian risk level based on the pedestrian information from the mobile terminal 1 and determines the vehicle risk level based on the vehicle information from the in-vehicle device 3. Is an application. That is, this risk management application functions as a risk determination unit. Specifically, the points assigned to the mobile terminal 1 and the vehicle-mounted device 3 are increased or decreased based on the operation information included in the pedestrian information and the vehicle information, and the degree of risk is determined according to the points. In particular, when specific operation information is received from the mobile terminal 1 or the in-vehicle device 3, an operation partner related to the specific operation information is searched, and the points are increased or decreased in consideration of both current points. . Further, the risk management application for the server device 4 sends a warning message according to the risk level of the pedestrian and the vehicle approaching each other based on the position information of the mobile terminal 1 and the in-vehicle device 3 to the mobile terminal 1 and the in-vehicle device. This is an application that notifies the device 3. That is, this risk management application functions as a risk notification unit.

  Next, the operation in the risk management system according to the present embodiment will be described with reference to FIGS. FIG. 8 is a sequence diagram for explaining an operation when determining a risk level in a pedestrian and a vehicle in the risk level management system according to the present embodiment. FIG. 9 is a sequence diagram for explaining an operation of notifying the pedestrian and the vehicle approaching each other of the risk level in the risk level management system according to the present embodiment. FIG. 10 is a sequence diagram for explaining the operation when specific operation information is detected by the in-vehicle device 3 according to the present embodiment.

  In the risk management system of the present invention, the server device 4 walks based on pedestrian information transmitted from the mobile terminal 1 via the mobile communication network 2 and vehicle information transmitted from the in-vehicle device 3. The risk level of the person and the vehicle is determined. And based on the positional information of the portable terminal 1 and the vehicle-mounted apparatus 3, it searches for the pedestrian and vehicle which mutually approach, and alerts the mobile terminal 1 and / or the vehicle-mounted apparatus 3 corresponding to these according to the risk level. A message is transmitted, and this warning message is displayed on the portable terminal 1 and / or the in-vehicle device 3.

  In the following, in the mobile terminal 1, the in-vehicle device 3, and the server device 4, it is assumed that the risk management application is activated in the application control unit 16, the application control unit 35, and the application control unit 46, respectively. The operation will be described. Further, it is assumed that a management table having the contents shown in FIG. 5 is registered in the point DB 43 of the server device 4.

  Further, it is assumed that the position information 64 in the pedestrian information DB 44 and the position information 74 in the vehicle information DB 45 are updated as needed according to the pedestrian information and the vehicle information. And when a certain portable terminal 1 and the vehicle-mounted apparatus 3 belong to the range in which the P2P communication control units 18 and 37 can communicate with each other, the server apparatus 4 directly communicates between the portable terminal 1 and the vehicle-mounted apparatus 3. It is assumed that processing necessary for performing the above is performed. Specifically, parameters for direct communication (the IP address of the portable terminal 1, the IP address of the in-vehicle device 3, the communication channel in the wireless LAN, and the SSID that is the identifier of the access point) are transmitted to both. As a result, the mobile terminal 1 and the in-vehicle device 3 belonging to the communicable range can directly communicate with each other.

  Furthermore, in the following, the specific motion information is referred to as motion information that can relate a pedestrian motion and a vehicle motion. For example, an operation in which the vehicle stops suddenly is applicable. That is, the sudden stop in the vehicle may be caused by carelessness of the driver of the vehicle, or may be caused by the pedestrian jumping out. In the former case, it is appropriate to deduct points that the driver (vehicle) has, but in the latter case, it is appropriate to deduct points that the pedestrian has. For this reason, in the risk management system according to the present embodiment, such movement information that can relate to the movement of the pedestrian and the movement of the vehicle is distinguished from other movement information as specific movement information. .

  In this risk management system, the mobile terminal 1 normally transmits pedestrian information to the server device 4 periodically (ST81). Specifically, the mobile terminal 1 transmits identification information, operation information, and position information to the server device 4. On the other hand, the in-vehicle device 3 periodically transmits vehicle information to the server device 4 (ST82). Specifically, the in-vehicle device 3 transmits identification information, operation information, and position information to the server device 4. When determining the danger level of a pedestrian and a vehicle, the server apparatus 4 determines whether specific operation information is contained in the operation information included in these pedestrian information and vehicle information (ST83).

  Here, when specific motion information is included in the motion information of the pedestrian information and the vehicle information, the motion partner in the specific motion information is searched (ST84). For example, when specific operation information is included in the operation information of the vehicle information, a pedestrian who is an operation partner in the specific operation information is searched. In the above-described example, when the specific operation information includes a sudden stop of the vehicle, it is determined whether there is a pedestrian who causes the sudden stop of the vehicle. This determination is made, for example, from position information and motion information included in pedestrian information received at substantially the same time as the specific motion information. In addition, when specific operation information is contained in the operation information of pedestrian information, the vehicle used as the operation other party in the specific operation information is searched.

  Hereinafter, the case where there is no operation partner in the specific operation information and the case where the operation partner exists will be described separately. First, a case where there is no operation partner in specific operation information will be described. When there is no motion partner in the specific motion information, the pedestrian information DB 44 and the vehicle information DB 45 are updated separately based on the motion information included in the pedestrian information and the motion information included in the vehicle information (ST85). , ST86).

  In this case, in the update process of the pedestrian information DB 44, the action information 52 registered in the point DB 43 is specified from the operation information and the position information included in the pedestrian information. Then, point information 53 corresponding to the behavior information 52 is added or subtracted with respect to the point information 62 of the corresponding record in the pedestrian information DB 44. Then, the risk rank information is updated according to the point information 62 after the addition or deduction. For example, when the specified action information 52 is “passing on the vehicle road” shown in FIG. 5, one point is deducted from the point information 62 of the corresponding record in the pedestrian information DB 44 shown in FIG. 6.

  Similarly, in the update process of the vehicle information DB 45, the action information 52 registered in the point DB 43 is specified from the operation information and the position information included in the vehicle information. Then, point information 53 corresponding to the behavior information 52 is added or subtracted with respect to the point information 72 of the corresponding record in the vehicle information DB 45. Then, the risk rank information is updated according to the point information 72 after the addition or deduction. For example, when the specified action information 52 is “exceeding legal speed (small)” shown in FIG. 5, one point is deducted from the point information 72 of the corresponding record in the vehicle information DB 45 shown in FIG.

  Next, a case where there is an operation partner in specific operation information will be described. When there is an operation partner in the specific operation information, the pedestrian information DB 44 and the vehicle are considered in consideration of the relationship between the operation information and position information included in the pedestrian information and the operation information and position information included in the vehicle information. Updated to the information DB 45 (ST85, ST86).

  In this case, in the update process of the pedestrian information DB 44 and the vehicle information DB 45, the action information 52 registered in the point DB 43 is specified from the specific operation information and position information. Then, it is determined whether the point information 53 corresponding to the behavior information 52 is to be added or subtracted with respect to any of the point information 62 of the corresponding record in the pedestrian information DB 44 and the point information 72 of the corresponding record in the vehicle information DB 45. Depending on the determination result, either point information 62 of the corresponding record in the pedestrian information DB 44 or point information 72 of the corresponding record in the vehicle information DB 45 is added or deducted. In the above-described example, when the specific operation information is a sudden stop of the vehicle and this sudden stop is caused by the pedestrian jumping, one point is deducted from the point information 62 of the corresponding record in the pedestrian information DB 44. On the other hand, when this sudden stop is caused by the driver's carelessness, one point is deducted from the point information 72 of the corresponding record in the vehicle information DB 45.

  In the risk management system according to the present embodiment, whether the cause of occurrence of such specific motion information exists in a pedestrian or in a vehicle (driver) is indicated in the corresponding record in the pedestrian information DB 44. The determination is made according to the point information 62 (or risk rank information 63) and the point information 72 (or risk rank information 73) of the corresponding record in the vehicle information DB 45. Specifically, if the point information 62 of the corresponding record in the pedestrian information DB 44 is lower than the point information 72 of the corresponding record in the vehicle information DB 45, it is determined that the cause of occurrence of the specific motion information exists in the pedestrian. On the contrary, if the point information 72 of the corresponding record in the vehicle information DB 45 is lower than the point information 62 of the corresponding record in the pedestrian information DB 44, it is determined that the cause of occurrence of the specific operation information exists in the vehicle (driver). To do. This determination is based on the fact that the point information 62 of the pedestrian information DB 44 and the point information 72 of the vehicle information DB 45 reflect the walking manner or driving manner of the pedestrian or driver, and from these, the pedestrian or driver. This is because it is considered that the behavior of can be estimated.

  On the other hand, when specific motion information is not included in the motion information of pedestrian information and vehicle information in ST83, the process directly proceeds to ST85, and the pedestrian information DB 44 and the vehicle information DB 45 are updated (ST85, ST86). In this case, the pedestrian information DB 44 and the vehicle are based on the motion information included in the pedestrian information and the motion information included in the vehicle information, as in the case where there is no motion partner in the specific motion information described above. The information DB 45 is updated separately.

  By repeating such processes from ST81 to ST86, a pedestrian information DB 44 as shown in FIG. 6 and a vehicle information DB 45 as shown in FIG. 7 are generated. In addition, although the server apparatus 4 receives pedestrian information from the portable terminal 1 and then receives vehicle information from the in-vehicle apparatus 3 and updates the pedestrian information DB 44 and the vehicle information DB 45, The update process of the pedestrian information DB 44 and the vehicle information DB 45 is not limited to this and can be changed as appropriate. For example, the transmission timing of pedestrian information and vehicle information, the detection timing of specific motion information, and the update timing of the pedestrian information DB 44 and the vehicle information DB 45 can be changed as appropriate.

  On the other hand, in this risk management system, when notifying a pedestrian and a vehicle approaching each other, as shown in FIG. 9, the server device 4 first selects an area for notifying the risk ( ST91). For example, the server device 4 selects an area where a pedestrian or vehicle having the lowest point information 62 in the pedestrian information DB 44 or the point information 72 in the vehicle information DB 45 exists. Note that the area selection by the server device 4 is not limited to this and can be changed as appropriate. For example, the area where the pedestrians or vehicles are most concentrated may be selected from the pedestrian information DB 44 or the vehicle information DB 45.

  Then, server device 4 selects a terminal (target terminal) to be notified of the degree of risk in the area (ST92). For example, the server device 4 includes the mobile terminal 1 having a high risk rank information 63 in the selected area based on the position information 64 registered in the pedestrian information DB 44 and the position information 74 registered in the vehicle information DB 45. Alternatively, the in-vehicle device 3 having a high risk rank information 73 is selected. In addition, about selection of the target terminal by such a server apparatus 4, it is not limited to this but can be changed suitably. For example, the target terminal may be selected based on the point information 62 registered in the pedestrian information DB 44 and the point information 72 registered in the vehicle information DB 45. In addition, it may be determined based on the risk rank information 63 (73) or the point information 62 (72) which of the portable terminal 1 and the in-vehicle device 3 is selected as the target terminal.

  Next, server device 4 selects a terminal (notification terminal) for notifying the degree of danger of the target terminal (ST93). For example, the server device 4 selects a notification terminal based on the position information 64 registered in the pedestrian information DB 44 and the position information 74 registered in the vehicle information DB 45. Specifically, the mobile terminal 1 or the in-vehicle device 3 existing in the traveling direction of the vehicle or the pedestrian estimated from the position information of the target terminal is searched, and the mobile terminal 1 or the in-vehicle device 3 is selected as the notification terminal.

  And the server apparatus 4 transmits the alert message according to the risk rank information 63 (73) of the target terminal to the selected notification terminal (ST94). For example, when the risk rank information 63 (73) of the target terminal is “A”, “the pedestrian (vehicle) is approaching ahead”, the risk rank information 63 (73) of the target terminal is “B”. "If a pedestrian (vehicle) is approaching ahead. Please be careful.", If the risk rank information 63 (73) of the target terminal is "C," A warning message such as “Pedestrian (vehicle) is approaching. Note that the alert message is not limited to these, and can be changed as appropriate. For example, any content may be used as long as the content can be distinguished according to the risk rank information 63 (73).

  When receiving the alert message, the mobile terminal 1 displays the alert message on the display unit 14 (ST95). Thereby, it becomes possible to alert the pedestrian carrying the mobile terminal 1 while reflecting the characteristics of vehicles approaching each other. Similarly, when receiving the alert message, the in-vehicle device 3 displays the alert message on the display unit 33 (ST96). Thereby, it becomes possible to alert the driver of the vehicle on which the in-vehicle device 3 is mounted while reflecting the characteristics of the approaching pedestrian.

In response to this, a warning message is sent. Specifically, as shown in FIG. 10, when the in-vehicle device 3 detects a specific operation (ST101), another terminal (here, referred to as the portable terminal 1) existing in the communicable range in the in-vehicle device 3 An alert message is transmitted to (ST102). In this case, it is preferable that a message corresponding to the detected specific action is transmitted as the alert message. For example, in the in-vehicle device 3, when a sudden stop of the vehicle is detected as a specific operation, a warning message such as “Beware of contact accidents with the vehicle” is transmitted. When receiving the alert message, the mobile terminal 1 displays the alert message on the display unit 14 (ST103). Thereby, it becomes possible to call attention of the pedestrian who carries the portable terminal 1. Note that even when a specific operation is detected in the mobile terminal 1, it is possible to alert the driver of the vehicle equipped with the in-vehicle device 3 in the same manner.

  Thus, in the risk management system according to the present embodiment, the pedestrian and vehicle risk are determined based on the position information of the mobile terminal 1 and the in-vehicle device 3 and the pedestrian and vehicle operation information.
