After storing the determination result in the storage 9, the controller 10 advances the processing to step S103.

  At step S103, the controller 10 determines whether or not 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 the user of the own device is in a safe place based on the charging state indicated by the obtained charging information, the determined moving state, and the estimation data 9F. After storing the estimation result in the storage 9, the controller 10 advances the processing to step S104.

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

The roadside device 200 is provided in a predetermined area or near a predetermined area. The predetermined area includes, for example, an area such as a road, an intersection, and a parking lot. 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 an unspecified number of electronic devices inside 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 such that radio waves from the roadside device 200 can be received, for example. 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 a driver. The 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 in-vehicle device 310 are configured to be capable of bidirectional communication with the indoor and outdoor electronic devices 1 via the communication unit. The roadside device 200 includes a function of transmitting information about a predetermined area. The in-vehicle device 310 includes a function of providing the user with the consulted information.

  For example, a user carrying the electronic device 1 charges 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 electronic device 1 is a stopped state. The electronic device 1 estimates that the user is in a safe place based on the estimation data 9F because the charging state is the charging state and the moving state of the own device is the stopped state. When the electronic device 1 estimates that the user is in a safe place, the electronic device 1 does not execute the notification processing to 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, the in-vehicle device 310 does not receive a notification from the electronic device 1 carried by the user in a safe place, and thus can provide only necessary information 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 charged state of the battery 40 is the charged state and the moving state of the electronic device 1 is the walking state. The electronic device 1 estimates that the user is not in a safe place based on the estimation data 9F because the charging state is the charged state and the moving state of the own device is the walking state. When it is estimated that the user is not in a safe place, a notification process to an external electronic device is executed. For example, when the roadside device 200 and the in-vehicle device 310 capable of communication exist near the electronic device 1, the electronic device 1 notifies the roadside device 200 and the in-vehicle device 310 of notification information for notifying the presence of the user. The radio wave including D is transmitted. As a result, the electronic device 1 can notify the roadside device 200, the in-vehicle device 310, and the like of the presence of the user, 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, the in-vehicle device 310 notifies the driver that, for example, a pedestrian at risk of jumping out is nearby. 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 vulnerable bicycle. 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, the in-vehicle device 310, etc. approaching the roadside device 200 of the notification. Information D can be transferred. As a result, the roadside device 200 can contribute to avoiding a traffic accident between the vehicle 300 and the traffic weak.

  For example, a user carrying the electronic device 1 is charging 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 state of charge of the battery 40 is the charging state and the state of movement of the electronic device 1 is the state of movement of the second vehicle. The electronic device 1 estimates that the user is not in a safe place based on the estimation data 9F because the charging state is the charging state and the moving state of the own device is the moving state of the second vehicle. When the electronic device 1 estimates that the user is not in a safe place, the electronic device 1 executes a notification process to an external electronic device. For example, when the in-vehicle device 310 capable of communication exists near 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 in-vehicle device 310. As a result, the electronic device 1 can notify the in-vehicle device 310 of the presence of the user, 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, the in-vehicle device 310 notifies the driver that, for example, a pedestrian at risk of jumping out is nearby. 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 vulnerable bicycle.

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

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

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

  In the example shown in FIG. 5, the estimation data 9F indicates that when the charging state is the charging state and the charging state, it can be estimated that the user is indoors when the moving state of the own device is the stopped state and the stationary state. Is shown. The estimation data 9F indicates that when the charging state is the charging state, the user can be estimated to be safe outdoors if the moving state of the own device 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 when the moving state of the own device is the moving state and traveling state of the second vehicle. The estimation data 9F indicates that when the charging state is the charging state and the post-charging state, indoor and outdoor cannot be estimated if the moving state of the own device is the walking state. The estimation data 9F estimates indoor and outdoor when the moving state of the own device is the moving state of the first vehicle, the moving state of the second vehicle, and the running state when the charging state is the charged state. Indicates that it cannot be done.

  The electronic device 1 can estimate whether or not the user of the own device is indoors based on the state of charge 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 electronic device 1 by combining the detection result of the charge state of the battery 40 and the moving state of the electronic device 1. The electronic device 1 can improve the method of using the determined movement state of the own device. Even in a place where the current position of the electronic device 1 cannot be detected, the electronic device 1 can estimate the surrounding environment of the own device using the trigger of charging of the battery 40 as a trigger.
