For example, when the charging state of the electronic device 1 is the charging state and the moving state is the moving state of the first vehicle, the user may be in a safe place such as in the vehicle. For example, when the electronic device 1 can be charged by a mobile battery, the electronic device 1 may be charged even when the moving state is a walking state or a traveling state. That is, when the electronic device 1 is in a charging state and the moving state is a moving state, a traveling state, or a walking state on a second vehicle (such as a bicycle), the user may not be in a safe place. There is sex.

  In the example illustrated in FIG. 2, the estimation data 9F indicates that the user is safe when the charging state is the charging state, and the mobile device is in a stopped state, a stationary state, or a moving state in the first vehicle.

Is shown.

  The electronic device 1 can estimate whether or not the user of the own device is in a safe place based on the charging state of the battery 40 and the moving state of the own device by referring to the estimation data 9F.

  In the present embodiment, the estimation data 9F describes a case where it can be estimated that the user is not in a safe place when the mobile device is in a walking state and the charging state is a charging state. Not. For example, when the mobile device is in a walking state and the charging state is a charging state, the user may be walking indoors. For this reason, the estimation data 9F may set information indicating that estimation is not performed when the mobile device is in a walking state and the charging state is a charging state.

  FIG. 3 is a flowchart illustrating a processing procedure of an example of control by the electronic device 1. The processing procedure shown in FIG. 3 is realized by the controller 10 executing the control program 9A. The processing procedure shown in FIG. 3 is repeatedly executed by the controller 10. The processing procedure shown in FIG. 3 may be repeatedly executed in response to detection of the start of charging of the battery 40, for example. The processing procedure shown in FIG. 3 may end the repeated execution when, for example, charging of the battery 40 ends and a predetermined time elapses.

  As illustrated in FIG. 3, the controller 10 of the electronic device 1 acquires charging information from the charging unit 41 as step S <b> 101. The controller 10 may store the acquired charging information in the charging data 9E. In step S102, the controller 10 determines the movement state of the own device. For example, the controller 10 determines the moving state of the own device based on the acceleration data 9B indicating the detection result of the acceleration sensor 15 and the determination data 9D. When the controller 10 stores the determination result in the storage 9, the process proceeds to step S103.

  In step S103, the controller 10 determines whether the user of the own device is in a safe place based on the charging state and the moving state. For example, the controller 10 estimates whether or not the user of the own device is in a safe place based on the charged state indicated by the acquired charging information, the determined moving state, and the estimated data 9F. When the controller 10 stores the estimation result in the storage 9, the process proceeds to step S104.

  As Step S104, the controller 10 determines whether or not it is estimated in Step S103 that the user is not in a safe place. If the controller 10 determines that the user is not in a safe place (Yes in step S104), the process proceeds to step S105.

  The controller 10 performs a notification process as step S105. For example, the notification process includes a process of transmitting a radio wave including notification information for notifying that a user is present to an external electronic device located in the vicinity of the own device via the communication unit 6. The notification information may include, for example, information indicating the movement state of the own device. The external electronic device includes, for example, a roadside machine, a vehicle, a vehicle-mounted device mounted on the vehicle, and the like. When the execution of the notification process ends, the controller 10 ends the processing procedure shown in FIG.

  If the controller 10 determines that the user is not estimated to be in a safe place (No in step S104), the controller 10 estimates that the user is in a safe place, so the notification process is not executed. Then, the processing procedure shown in FIG.

  In the example illustrated in FIG. 3, the processing procedure has been described with respect to the procedure for determining the movement state of the own device after acquiring the charging information, but is not limited thereto. For example, the processing procedure may be a procedure for acquiring charging information after determining the movement state of the own device.

  FIG. 4 is a system diagram illustrating an example of a system configuration of the notification system 100. An example of the notification system 100 including the electronic device 1 will be described with reference to FIG.

  As shown in FIG. 4, the notification system 100 includes the electronic device 1, a roadside device 200, and a vehicle 300. The roadside machine 200 is provided in a predetermined area or in the vicinity of the predetermined area. The predetermined area includes, for example, areas such as roads, intersections, and parking lots. The predetermined area may be, for example, an area including a place where a traffic accident may occur. The roadside device 200 can transmit radio waves to a large number of unspecified electronic devices in and near a predetermined area. The vehicle 300 includes, for example, an automobile, a truck, a bus, a taxi, an emergency vehicle, and the like. The vehicle 300 includes an in-vehicle device 310. The in-vehicle device 310 is mounted on the vehicle 300 so that, for example, radio waves from the roadside device 200 can be received. The vehicle-mounted device 310 includes a vehicle-mounted device mounted on the vehicle 300 such as a navigation device, an ETC (Electronic Toll Collection System) vehicle-mounted device, a combination meter, and a car audio. The in-vehicle device 310 may be, for example, an electronic device that is brought into the vehicle 300 by the driver. Electronic devices brought into the vehicle 300 include, for example, a smartphone, a mobile phone, a wearable device, a portable game machine, and the like.

  The roadside device 200 and the in-vehicle device 310 have a communication unit. The roadside device 200 and the in-vehicle device 310 are configured to be capable of bidirectional communication with each other via a communication unit. The roadside device 200 and the vehicle-mounted device 310 are configured to be able to perform bidirectional communication with the indoor and outdoor electronic devices 1 via the communication unit. The roadside device 200 includes a function of transmitting information related to a predetermined area. The in-vehicle device 310 includes a function of providing the received information to the user.

  For example, a user carrying the electronic device 1 is charging the battery 40 of the electronic device 1 in a building 500 such as a home or a company in a stopped state. In this case, the electronic device 1 determines that the charging state of the battery 40 is a charging state and the moving state of the own device is a stopped state. Based on the estimated data 9F, the electronic device 1 estimates that the user is in a safe place because the charged state is the charging state and the mobile device is in the stopped state. When it is estimated that the user is in a safe place, the electronic device 1 does not execute the notification process for the external electronic device. As a result, since the electronic device 1 does not operate the communication unit 6, an increase in power consumption can be suppressed. On the other hand, since the vehicle-mounted device 310 does not receive a notification from the electronic device 1 carried by a user in a safe place, only the necessary information can be provided to the driver.

  Thereafter, the user has finished charging the battery 40 of the electronic device 1 and has moved from the building 500 to the outside by walking. In this case, the electronic device 1 determines that the state of charge of the battery 40 is a post-charge state, and the movement state of the own device is a walking state. Based on the estimated data 9F, the electronic device 1 estimates that the user is not in a safe place because the state of charge is the post-charge state and the mobile device is in the walking state. When it is estimated that the user is not in a safe place, a notification process for an external electronic device is executed. For example, when the roadside device 200 and the vehicle-mounted device 310 that can communicate with each other exist in the vicinity of the electronic device 1, the electronic device 1 notifies the roadside device 200 and the vehicle-mounted device 310 of the presence of the user. Transmit radio waves including D. As a result, the electronic device 1 can notify the presence of the user to the roadside device 200, the in-vehicle device 310, and the like, so that the safety of the user can be improved. On the other hand, when the in-vehicle device 310 receives the notification information D from the electronic device 1 carried by a user who is not in a safe place, for example, the vehicle-mounted device 310 notifies the driver that there is a pedestrian at risk of jumping out. be able to. As a result, it is possible to improve the possibility that the driver can avoid a traffic accident with a pedestrian or a bicycle weak person. Further, when the roadside device 200 receives the notification information D from the electronic device 1 carried by a user who is not in a safe place, for example, the roadside device 200 notifies the vehicle 300 approaching the roadside device 200, the vehicle-mounted device 310, and the like. Information D can be transferred. As a result, the roadside machine 200 can contribute to avoiding a traffic accident between the vehicle 300 and a vulnerable person.

  For example, a user carrying the electronic device 1 charges the battery 40 of the electronic device 1 while moving outdoors on a second vehicle (bicycle). In this case, the electronic device 1 determines that the charging state of the battery 40 is a charging state and the movement state of the own device is a movement state of the second vehicle. Based on the estimation data 9F, the electronic device 1 estimates that the user is not in a safe place because the charging state is the charging state and the movement state of the own device is the movement state of the second vehicle. When the electronic device 1 estimates that the user is not in a safe place, the electronic device 1 performs a notification process for an external electronic device. For example, when there is a vehicle-mounted device 310 that can communicate in the vicinity of the electronic device 1, the electronic device 1 transmits a radio wave including notification information D for notifying the presence of the user to the vehicle-mounted device 310. As a result, since the electronic device 1 can notify the vehicle-mounted device 310 of the presence of the user, the safety of the user can be improved. On the other hand, when the in-vehicle device 310 receives the notification information D from the electronic device 1 carried by a user who is not in a safe place, for example, the vehicle-mounted device 310 notifies the driver that there is a pedestrian at risk of jumping out. be able to. As a result, it is possible to improve the possibility that the driver can avoid a traffic accident with a pedestrian or a bicycle weak person.

  In the above-described embodiment, the electronic device 1 has been described based on a case where it is estimated whether or not the user is in a safe place based on the charged state of the battery 40 and the moving state of the own device. However, the present invention is not limited to this. . For example, the electronic device 1 may estimate whether the user is indoors based on the state of charge of the battery 40 and the movement state of the own device.

  FIG. 5 is a diagram illustrating another example of the estimation data 9F. Another example of the relationship between the charged state of the battery 40 and the moving state of the own device indicated by the estimated data 9F will be described with reference to FIG.

  For example, when the charging state of the electronic device 1 is a charging state and the moving state is a stop state or a stationary state, the user may be indoors. For example, when the charging state of the electronic device 1 is a charging state and the movement state is a movement state of the first vehicle, the user may be in a safe vehicle. For example, when the electronic device 1 can be charged by a mobile battery, the electronic device 1 may be charged even when the moving state is a walking state or a traveling state. However, the user is unlikely to run indoors or ride a bicycle. Therefore, when the charging state of the electronic device 1 is a charging state and the moving state is a moving state or a traveling state on a second vehicle (such as a bicycle), the user may be outdoors. When the charging state of the electronic device 1 is a charging state and the moving state is a walking state, the user may be outdoors or indoors.

  In the example illustrated in FIG. 5, the estimation data 9F can be estimated that the user is indoors when the charging state is the charging state and the post-charging state, and the mobile device is in the stopped state or the stationary state. Is shown. The estimated data 9F indicates that when the charging state is the charging state, it can be estimated that the user is in a safe outdoor area when the moving state of the vehicle is the moving state of the first vehicle. The estimation data 9F indicates that when the charging state is the charging state, it can be estimated that the user is outdoors if the moving state of the own device is the moving state or the traveling state of the second vehicle. The estimation data 9F indicates that when the charging state is a charging state and a post-charging state, indoor and outdoor cannot be estimated if the mobile device is in a walking state. The estimation data 9F estimates indoors and outdoors when the state of charge is the state after the charge when the state of movement of the vehicle is the state of movement in the first vehicle, the state of movement in the second vehicle, and the traveling state. Indicates that it is not possible.

  The electronic device 1 can estimate whether or not the user of the own device is indoors based on the charging state of the battery 40 and the moving state of the own device by referring to the estimation data 9F. The electronic device 1 can improve the estimation accuracy of the surrounding environment of the own device by combining the detection results of the charged state of the battery 40 and the moving state of the own device. The electronic device 1 can improve the method of using the determined movement state of the own device. The electronic device 1 can estimate the surrounding environment of the own device by using the start of charging of the battery 40 as a trigger even in a place where the current position of the own device cannot be detected.
