  As illustrated in FIG. 5, the control unit 100 includes a step counting unit 300, a state specifying unit 400, and a notification determining unit 500 as functional blocks. At least one of the step count measurement unit 300, the state identification unit 400, and the notification determination unit 500 may be realized by a hardware circuit that does not require software to execute its function.

  When the control unit 100 includes a main CPU and a sub CPU, some of the functional blocks shown in FIG. 5 are realized by the sub CPU, and the remaining functional blocks are replaced by the main CPU. May be realized. For example, the stop movement specifying unit 410 may be realized by a sub CPU, and the remaining functional blocks may be realized by a main CPU.

  The stop movement specifying unit 410 can perform stop movement specification for specifying the state of the user 9 regarding the stop and movement of the user 9. In the stop movement specification, the stop movement specifying unit 410 can specify that the user 9 is stopped and that the user 9 is moving. In other words, the stop movement specifying unit 410 can determine whether the state of the user 9 is a stopped state or a moving state. Furthermore, in other words, the stop movement specifying unit 410 can determine whether the user 9 is moving. The stop movement specifying unit 410 determines that the user 9 has stopped and that the user 9 has moved based on at least one of the position information acquired by the reception unit 140 and the acceleration detected by the acceleration sensor 200, for example. It is possible to specify that

  Further, the stop movement specifying unit 410 can specify the stop of the user 9 and the start of the movement of the user 9 in the stop movement specification. When the state of the user 9 changes from the moving state to the stopped state, the stop movement specifying unit 410 determines that the user 9 has stopped. When the state of the user 9 changes from the stopped state to the moving state, the stop movement specifying unit 410 determines that the user 9 has started moving.

  Since the stop of the user 9 can be said to be the stop of the movement of the electronic device 10, it can be said that the stop movement specifying unit 410 can specify the stop of the movement of the electronic device 10. In addition, since the movement start of the user 9 can be said to be the movement start of the electronic device 10, it can be said that the stop movement specifying unit 410 can specify the movement start of the electronic device 10.

  The timing at which the state of the user 9 changes from the stopped state to the moving state can be said to be the stop timing of the user 9 and the movement stop timing of the electronic device 10. The stop movement specifying unit 410 can specify the movement start timing of the user 9, in other words, the movement start timing of the electronic device 10 in the stop movement specification. The timing at which the state of the user 9 changes from the moving state to the stopped state can be said to be the movement start timing of the user 9 and the movement start timing of the electronic device 10. The stop movement specifying unit 410 can specify the movement start timing of the user 9, in other words, the movement start timing of the electronic device 10 in the stop movement specification.

  In addition, the stop movement specifying unit 410 can specify the moving means of the user 9 when determining that the user 9 is moving in the stop movement specification. For example, based on the acceleration detected by the acceleration sensor 200, the stop movement specifying unit 410 determines whether the user 9 is moving on its own without riding on a vehicle or whether the user 9 is moving on a vehicle. Can be identified. Here, that the user 9 moves on his own means that the user 9 moves on his own feet without riding on a vehicle. If the movement of the user 9 by himself / herself is referred to as “self-movement”, it can be said that the stop movement specifying unit 410 can specify the self-movement of the user 9. When the movement of the user 9 on the vehicle is referred to as “vehicle movement”, the stop movement specifying unit 410 can specify the vehicle movement of the user 9.

  The self-powered movement that can be specified by the stop movement specifying unit 410 includes the user 9 walking and moving, and the user 9 running and moving. When the running of the user 9 is referred to as “running”, the self-movement includes walking and running. In addition, the vehicle movement that can be specified by the stop movement specifying unit 410 includes the user 9 moving by bicycle and the user 9 moving faster than a bicycle such as an automobile, a train, and a bus. And traveling on other vehicles.

  Hereinafter, in order to distinguish between a bicycle and a vehicle that can move faster, simply referring to “vehicle” means a vehicle that can move faster than a bicycle. In addition, when the user 9 moves by himself, “self” is used as the name of the moving means, and when the user 9 walks, “walking” is used as the name of the moving means, and the user 9 runs and moves. "Run" is used as the name of the means of transportation in the case.

  Here, it is known that the acceleration of the electronic device 10 indicates a peculiar time change pattern according to the moving means of the user 9 holding the electronic device 10. When the pattern of the time change of the acceleration detected by the acceleration sensor 200 indicates a pattern corresponding to “walking”, the stop movement specifying unit 410 specifies that the moving means of the user 9 is “walking”. When the pattern of the time change of the acceleration detected by the acceleration sensor 200 indicates a pattern corresponding to “running”, the stop movement specifying unit 410 specifies that the moving means of the user 9 is “running”. I do. Further, when the pattern of the time change of the acceleration detected by the acceleration sensor 200 indicates a pattern corresponding to “bicycle”, the stop movement specifying unit 410 specifies that the moving means of the user 9 is “bicycle”. I do. When the time change pattern of the acceleration detected by the acceleration sensor 200 indicates a pattern corresponding to “vehicle”, the stop movement specifying unit 410 specifies that the moving means of the user 9 is “vehicle”. I do.

  In this way, the stop movement specifying unit 410 can specify whether the moving means of the user 9 is walking, running, cycling, or a vehicle. The control unit 100 can cause the display unit 120 to display, for example, the moving means specified by the stop movement specifying unit 410 and the moving distance of the user 9 (the moving distance of the electronic device 10). Accordingly, the user 9 can distinguish and confirm the walking distance, the traveling distance, the traveling distance by bicycle, and the traveling distance by vehicle. The control unit 100 can determine the moving distance of the user 9 based on the position information acquired by the receiving unit 140, for example.

  The motion information acquisition unit 420 can acquire motion information indicating the motion of the user 9. The motion information includes, for example, at least one of the continuous stop time of the user 9, the continuous walking time of the user 9, the number of continuous walking steps of the user 9, and the traveling direction of the user 9. This motion information will be described later in detail.

  The in-vehicle determination unit 430 can perform an in-vehicle determination that determines whether the user 9 is present in the vehicle 6. Hereinafter, the inside of the vehicle 6 may be referred to as “inside the vehicle”. Further, the presence of the user 9 in the vehicle 6 may be simply referred to as “inside the vehicle”, and the absence of the user 9 in the vehicle 6 may be simply referred to as “outside the vehicle”. The in-vehicle determination will be described later in detail.

  The indoor determination unit 440 can determine whether or not the user 9 exists in a building such as a house, a building, and a shop. That is, the indoor determination unit 440 can perform the indoor determination that determines whether the user 9 exists indoors. Hereinafter, the presence of the user 9 indoors may be simply referred to as “indoor”, and the absence of the user 9 indoors may be simply referred to as “outdoor”. The indoor judgment will be described later in detail.

  The position determination unit 450 can determine whether the user 9 is located in a predetermined area (predetermined location). In other words, the position determination unit 450 can determine whether the electronic device 10 is located in a predetermined area (predetermined location). As the predetermined area, for example, an area including a place where an accident between the pedestrian and the vehicle 6 is likely to occur and a vicinity thereof is adopted. The predetermined area includes, for example, an intersection area including the intersection 2 and its vicinity, a T-shaped road area including a T-shaped road and its vicinity, and a school road area including a child's school road and its vicinity.

  The position determination unit 450 can determine whether or not the user 9 is located in a predetermined area based on, for example, the position information acquired by the reception unit 140 and the map information stored in the storage unit 103. It is. In addition, the position determination unit 450 determines whether the user 9 is located in the predetermined area based on whether the wireless communication unit 110 can receive a signal from the roadside device 5 disposed at the intersection 2 or the like. You may.

  As described above, the state specifying unit 400 can specify various states of the user 9. The type of the state of the user 9 specified by the state specifying unit 400 is not limited to the above.

  The number-of-steps measuring section 300 can measure the number of steps of the user 9 who is moving by himself. The number-of-steps measuring unit 300 measures the number of steps of the user 9 who is moving by himself, for example, based on the acceleration detected by the acceleration sensor 200. The step counting unit 300 counts the number of steps of the user 9 when the stop movement specifying unit 410 specifies that the user 9 is walking or running. The control unit 100 can cause the display unit 120 to display the number of steps measured by the number-of-steps measuring unit 300. Hereinafter, the number of steps measured by the step number measurement unit 300 may be simply referred to as “measured step number”.

  The notification determination unit 500 can perform a determination process of determining whether or not the electronic device 10 sends a notification to the outside of the electronic device 10 based on the state of the user 9 specified by the state specification unit 400. is there.

  For example, when the position determination unit 450 determines that the user 9 is located in the intersection area and the stop-movement specifying unit 410 specifies that the travel mode of the user 9 is “running”, the notification determination unit 500 determines whether the electronic device 10 The electronic device 10 determines that the notification is made to the outside. In addition, when the position determination unit 450 determines that the user 9 is located in the intersection area and the stop-movement specifying unit 410 specifies that the moving means of the user 9 is “bicycle”, the electronic device 10 The electronic device 10 determines that the notification is made to the outside. When the notification determination unit 500 determines that the electronic device 10 sends a notification to the outside of the electronic device 10, for example, the notification that the user 9 (pedestrian) is present near the vehicle 6 located in the intersection area. Notification from the wireless communication unit 110 to the roadside device 5. The presence notification information may include information indicating the moving means of the user 9 specified by the stop movement specifying unit 410. The roadside device 5 transmits the received presence notification information to the vehicles 6 existing in the intersection area. At this time, the roadside device 5 transmits the presence notification information by broadcast, for example. The vehicle 6 warns, for example, a driver based on the received presence notification information. The vehicle 6 notifies the driver that a pedestrian is nearby by using, for example, a car navigation device. Thereby, the driver of the vehicle 6 existing in the intersection area can drive while recognizing that a person exists in the intersection area. As a result, driving safety of the vehicle 6 is improved. Hereinafter, the notification of the electronic device 10 to the outside of the electronic device 10 may be referred to as “notification execution”. The fact that the electronic device 10 does not notify the outside of the electronic device 10 may be referred to as “notification not executed”.

  Note that the content of the information notified by the electronic device 10 to the outside is not limited to the above example. Further, the electronic device 10 can directly notify the vehicle 6.

<Example of operation flow of electronic equipment>
FIG. 6 is a flowchart illustrating an example of an operation of the electronic device 10 until the electronic device 10 notifies the outside. The electronic device 10 repeatedly executes a series of processes of steps s1 to s6 shown in FIG. 6 regularly or irregularly.

  As shown in FIG. 6, in step s1, the position determination unit 450 determines whether the electronic device 10 is located in a predetermined area. When it is determined in step s1 that the electronic device 10 is located in the predetermined area, in step s2, the stop movement specifying unit 410 performs stop movement specification. If it is not determined in step s1 that the electronic device 10 is located in the predetermined area, step s1 is executed again.

  If the user 9 is moving in the stop movement specification in step s2 and the moving means is specified as “vehicle”, in step s6, the notification determination unit 500 determines not to perform the notification. If the vehicle of the user 9 is a vehicle such as an automobile, a train, a bus, or the like, the user 9 warns the driver of the vehicle 6 because the possibility of the user 9 being safe for the vehicle 6 is high. It can be said that there is little need. Therefore, the notification determining unit 500 determines that the electronic device 10 does not notify the outside when the moving means of the user 9 is specified as “vehicle”. Thereby, when the user 9 is safe for the vehicle 6, it is possible to reduce the possibility that the driver of the vehicle 6 receives information that is not so necessary. Therefore, it is possible to reduce the possibility that the driver of the vehicle 6 feels annoyed by receiving information that is not so necessary. When step s6 is executed, the electronic device 10 executes step s1 again, and operates similarly thereafter.

  If the user 9 is moving in the stop movement specification in step s2 and the movement means is specified as “running”, step 5 is executed. If the user 9 is moving in the stop movement specification and the means of movement is specified as “bicycle”, step 5 is executed. In step s5, the notification determining unit 500 determines to execute the notification. In the case where the traveling means of the user 9 is “running” and “bicycle”, it is difficult to say that the user 9 is safe for the vehicle 6. Therefore, the notification determination unit 500 determines that the electronic device 10 sends a notification to the outside when the user's 9 means of transportation is “running” or “bicycle”. When step s5 is executed, the electronic device 10 executes step s1 again, and thereafter operates similarly.

  When the notification determining unit 500 determines to execute the notification, for example, the above-described presence notification information is notified from the wireless communication unit 110 to the roadside device 5. The roadside device 5 notifies the vehicle 6 existing in the predetermined area of the received presence notification information. If it is determined in step s1 that the electronic device 10 is present in, for example, a T-shaped road area, the roadside device 5 provided in the T-shaped road area transmits the presence notification information received from the electronic device 10 to the T-shaped road area. Is notified to the vehicle 6 existing in the vehicle. The vehicle 6 warns the driver based on the received presence notification information. Note that the presence notification information may be directly notified from the electronic device 10 to the vehicle 6 existing in the T-shaped road area.

  If it is specified that the user 9 has stopped in the stop movement specification in step s2, the indoor determination unit 440 performs indoor determination in step s3. Further, in the stop movement specification, when the user 9 is moving and the moving means is specified as “walking”, the indoor determination unit 440 performs indoor determination in step s3.

  If it is determined that the room is “indoor” in the indoor determination in step s3, step s6 is executed, and non-execution of notification is determined. When the user 9 exists in a building such as a building, there is a high possibility that the user 9 is safe for the vehicle 6. Therefore, when it is determined that the user 9 exists indoors, it is determined that the electronic device 10 does not notify the outside.

  On the other hand, when it is determined that the vehicle is “outdoor” in the indoor determination in step s3, the in-vehicle determination unit 430 performs in-vehicle determination in step s4. If it is determined in the in-vehicle determination that the state is "in-vehicle", step s6 is executed to determine not to perform the notification. When the user 9 is present in the vehicle 6, there is a high possibility that the user 9 is safe with respect to the other vehicles 6. Therefore, when it is determined that the user is present in the vehicle, it is determined that the electronic device 10 does not notify the outside.

  If it is determined that "outside the vehicle" in the in-vehicle determination in step s4, that is, if it is determined that the user 9 is not present indoors and is not present inside the vehicle, step s5 is executed and notification execution is determined. When the user 9 is outside and outside the vehicle, it is difficult to say that the user 9 is safe for the vehicle 6. Therefore, when it is determined that the user 9 does not exist indoors and does not exist inside the vehicle, it is determined that the electronic device 10 notifies the outside.

  Note that, instead of step s6, the notification determination unit 500 may determine the execution of the notification. In this case, for example, notification information for notifying that there is a low risk that the nearby user 9 jumps out onto the roadway is notified from the electronic device 10 via the roadside device 5 or directly to the vehicle 6. Is also good.

  Further, as shown in FIG. 7, the stop movement identification in step s2 may not be executed. In this case, when it is determined in step s1 that the electronic device 10 exists in the predetermined area, the indoor determination in step s3 is performed.

  Further, as shown in FIG. 8, step s1 may not be executed. In the example of FIG. 8, step s1 is not executed in the flow of FIG. 7, but step s1 may not be executed in the flow of FIG. In this case, when step s5 is executed, step s2 is executed again, and when step s6 is executed, step s2 is executed again.

  Further, as shown in FIG. 9, after the indoor determination and the in-vehicle determination are performed, step s1 may be executed. In the example of FIG. 9, the indoor determination is performed in step s3, and then the in-vehicle determination is performed in step s4. Then, step s1 is executed. In step s1, when it is determined that the electronic device 10 is located in the predetermined area, in step s15, the notification determination unit 500 determines the electronic device 10 based on the indoor determination result in step s3 and the in-vehicle determination result in step s4. Performs a determination process to determine whether or not to notify outside. In step s15, when it is determined that the indoor determination is “indoor”, the notification determining unit 500 determines not to perform the notification. In addition, when it is determined that “inside the vehicle” in the in-vehicle determination, notification determination unit 500 determines that notification is not to be performed. Then, the notification determination unit 500 determines to execute the notification when it is determined that “outdoor” is determined in the indoor determination and “outside the vehicle” is determined in the in-vehicle determination.

  Note that, in the example of FIG. 9, stop movement identification is not performed, but stop movement identification may be performed before step s1. In this case, in step s15, the notification determination unit 500 determines whether the electronic device 10 notifies the outside based on the result of the stop movement identification, the result of the indoor determination, and the result of the in-vehicle determination. decide. For example, the notification determination unit 500 determines that the moving means is "vehicle" in the stop movement specification, that the vehicle is determined to be "indoor" in the indoor determination, and that the vehicle is determined to be "in the vehicle" in the in-vehicle determination. In such a case, the non-execution of the notification is determined. The notification determining unit 500 determines to execute the notification when the moving means is “running” in the stop movement specification and when the moving means is “bicycle” in the stop movement specification. I do. Then, the notification determination unit 500 determines to execute the notification when the indoor determination is determined to be “outdoor” and the interior determination is determined to be “outside the vehicle”.

  In each of the above examples, the order of executing the indoor determination and the in-vehicle determination may be reversed. Further, the indoor determination and the in-vehicle determination may be performed in parallel. Further, one of the indoor determination and the in-vehicle determination may not be performed.

  As described above, the notification determination unit 500 performs the determination process of determining whether or not the electronic device 10 sends a notification to the outside based on the result of the in-vehicle determination. The possibility of giving a notification can be reduced. Therefore, the convenience of the electronic device 10 is improved.

  In addition, the notification determination unit 500 performs a determination process of determining whether or not the electronic device 10 sends a notification to the outside based on the result of the indoor determination. Performance can be reduced. Therefore, the convenience of the electronic device 10 is improved.

  6, 7, and 9, the notification determination unit 500 performs the determination process when the electronic device 10 is located in the predetermined region, and performs the determination process when the electronic device 10 is not located in the predetermined region. Therefore, the electronic device 10 can determine whether or not the electronic device 10 notifies the outside when necessary.

  6 and 7, the in-vehicle determination unit 430 performs the in-vehicle determination when the electronic device 10 is located in the predetermined region, and does not perform the in-vehicle determination when the electronic device 10 is not located in the predetermined region. Therefore, the electronic device 10 can perform the in-vehicle determination when necessary.

  6 and 7, the indoor determination unit 440 performs indoor determination when the electronic device 10 is located in the predetermined region, and does not perform indoor determination when the electronic device 10 is not located in the predetermined region. Therefore, the electronic device 10 can perform indoor determination when necessary.

  In the example of FIG. 6, the in-vehicle determination unit 430 does not perform the in-vehicle determination when the moving means is “vehicle”, “running”, and “bicycle” in the stop movement specification. Is determined to be “walking”, an in-vehicle determination is made. As described above, the in-vehicle determination unit 430 performs the in-vehicle determination according to the type of the moving means specified by the stop movement specification, thereby simplifying the processing of the electronic device 10 as compared with the case where the in-vehicle determination is always performed. Be transformed into

  In the example of FIG. 6 and the like, the indoor determination unit 440 does not perform the indoor determination when the moving means is specified as “vehicle”, “running”, and “bicycle” in the stop movement specification. Is determined to be “walking”, indoor determination is performed. As described above, the indoor determination unit 440 performs the indoor determination according to the type of the moving means specified by the stop movement specification, thereby simplifying the processing of the electronic device 10 as compared with the case where the indoor determination is always performed. Be transformed into

<In-vehicle judgment>
Next, details of the in-vehicle determination will be described. Hereinafter, a plurality of examples of the in-vehicle determination will be described.

<First example of in-vehicle determination: in-vehicle determination based on presence / absence of communication connection setting>
In the present example, the in-vehicle determination unit 430 has a setting (hereinafter, may be referred to as a “communication connection setting”) necessary for communication connection between the communication device mounted on the vehicle 6 and the wireless communication unit 110. It is determined whether or not the user 9 is present in the vehicle 6 based on whether or not the operation is performed at 10. The in-vehicle determination unit 430 determines that the user 9 is present in the vehicle when the communication connection setting is performed on the electronic device 10. On the other hand, when the communication connection setting is not performed on the electronic device 10, the in-vehicle determination unit 430 determines that the user 9 does not exist in the vehicle. Hereinafter, the communication device mounted on the vehicle 6 may be referred to as an “in-vehicle communication device”.

  Examples of the in-vehicle communication device include an electronic device corresponding to at least one of Bluetooth and Wi-Fi. Such an in-vehicle communication device includes a car audio device and a car navigation device compatible with at least one of Bluetooth and Wi-Fi.

  When the pairing is completed between the Bluetooth compatible in-vehicle communication device and the electronic device 10, a communication connection setting required for the communication connection between the in-vehicle communication device and the wireless communication unit 110 is performed on the electronic device 10. The in-vehicle determination unit 430 determines “in-vehicle” when the completion of pairing between the in-vehicle communication device supporting Bluetooth and the electronic device 10 can be confirmed. On the other hand, if the completion of the pairing cannot be confirmed, the in-vehicle determination unit 430 determines “outside the vehicle”.

  The communication connection setting required for communication connection between the Wi-Fi compatible in-vehicle communication device functioning as an access point and the electronic device 10 is determined by a security key (also called a password or an encryption key) assigned to the in-vehicle communication device. ) Is input to the electronic device 10. When the wireless communication unit 110 receives the SSID (Service Set Identifier) transmitted by the in-vehicle communication device compatible with Wi-Fi and the security key corresponding to the SSID is stored in the storage unit 103, It is determined that the vehicle is in the vehicle. On the other hand, the in-vehicle determination unit 430 determines “outside the vehicle” when the security key corresponding to the SSID received from the wireless communication unit 110 from the in-vehicle communication device supporting Wi-Fi is not stored in the storage unit 103. I do.

  As described above, the in-vehicle determination unit 430 determines whether or not the user 9 is present in the vehicle based on whether or not the communication connection setting is performed on the electronic device 10, so that the electronic device 10 It can be more correctly determined whether or not is present in the vehicle.

<Second example of in-vehicle determination: in-vehicle determination based on movement of electronic device>
When the user 9 is present in the vehicle 6 of another person instead of the vehicle 6 owned by the user 9, the electronic device 10 of the user 9 and the communication device mounted on the vehicle 6 of the other person perform communication connection. There is a possibility that the necessary communication connection settings have not been made in the electronic device 10. Therefore, in the above “first example of the in-vehicle determination”, when the user 9 is present in the vehicle 6 of another person, the in-vehicle determination unit 430 may not be able to properly determine that the user 9 is present in the vehicle. is there.

  On the other hand, when the plurality of users 9 are present in the same vehicle 6, the plurality of electronic devices 10 respectively owned by the plurality of users 9 are likely to move in the same manner.

  Therefore, in this example, the in-vehicle determination unit 430 included in the electronic device 10 determines the movement of the other electronic device 10 that determines that the user 9 of the other electronic device 10 is present in the vehicle, Based on the movement of the device 10, it is determined whether the user 9 of the electronic device 10 is present in the vehicle. Thereby, the electronic device 10 can correctly determine whether the user 9 is present in the vehicle even if the communication connection setting is not performed.

  Hereinafter, the electronic device 10 whose operation is to be described may be referred to as “own device 10”. The user 9 of the own device 10 may be referred to as “own user 9”. An electronic device 10 different from the own device 10 may be referred to as “other device 10”. The user 9 of the other device 10 may be referred to as “other user 9”. The in-vehicle determination unit 430 determines whether or not the own user 9 is in the vehicle based on the movement of the other device 10 that determines that the other user 9 is in the vehicle and the movement of the own device 10. In this example, as in FIGS. 7 to 9 described above, it is assumed that stop movement identification in step s2 is not performed.

  In the in-vehicle determination of this example, the plurality of electronic devices 10 (the plurality of electronic devices 10 owned by the driver and the passenger) in the same vehicle 6 can communicate with each other using Bluetooth or the like. It is assumed that there is. For example, the own user 9 operates the display area 12 of the own device 10 and the like to set a pairing between the own device 10 and another device 10 existing in the same vehicle 6 as the own device 10. Thereby, the plurality of electronic devices 10 existing in the same vehicle 6 can communicate with each other using Bluetooth.

  In this example, when the in-vehicle determination unit 430 determines that the user 9 is present in the vehicle, the electronic device 10 stops moving each time the electronic device 10 stops moving. That is, the movement stop timing is notified to another electronic device 10 with which the electronic device 10 can communicate, using Bluetooth or the like. The electronic device 10 can specify the movement stop timing of the electronic device 10 based on the result of the stop movement specification by the stop movement specifying unit 410.

  FIG. 10 is a flowchart illustrating an example of the in-vehicle determination according to the present example. As shown in FIG. 10, in step s21, the in-vehicle determination unit 430 confirms whether or not a communication connection setting has been made to the own device 10, as in the first example of the in-vehicle determination. When the communication connection setting is performed on the own device 10, the in-vehicle determination unit 430 determines that the own user 9 is present in the vehicle in step s24. When the own user 9 is present in the vehicle 6 owned by the own user 9, it may be determined in step s21 that the communication connection setting is performed on the own device 10.

  On the other hand, when the communication connection setting is not performed on the own device 10, the in-vehicle determining unit 430 notifies the movement stop timing from the other device 10 that determines that the other user 9 is present in the vehicle in step s <b> 22. It is determined whether or not. When the own user 9 is present in the vehicle 6 of another person, it may be determined in step s21 that the communication connection setting has not been performed on the own device 10.

  When determining in step s22 that the movement stop timing is not notified from the other device 10, the in-vehicle determination unit 430 determines in step s25 that the user 9 is not present in the vehicle. When the movement stop timing is not notified to the own device 10 from the other device 10 that determines that the other user 9 is present in the vehicle, there is a high possibility that the own device 10 exists apart from the other device 10. Therefore, when it is determined in step s22 that the movement stop timing is not notified from the other device 10, it is highly likely that the user 9 does not exist in the vehicle.

  On the other hand, when it is determined that the movement stop timing is notified from the other device 10, the in-vehicle determination unit 430 determines the own user 9 based on the notified movement stop timing and the movement stop timing of the own device 10. Is determined in the vehicle. The in-vehicle determination unit 430 can specify the timing of stopping the movement of the own device 10 based on the result of the stop movement identification performed by the stop movement identification unit 410.

  Here, if the movement stop timing of the other device 10 that determines that the other user 9 is present in the vehicle is close to the movement stop timing of the own device 10, the own user 9 is in the same vehicle 6 as the other user 9. Likely to exist.

  Therefore, when determining in step s22 that the movement stop timing is notified from the other device 10, the in-vehicle determination unit 430 is notified from the other device 10 that determines that the other user 9 is present in the vehicle in step s23. A stop timing comparison is performed to determine whether or not the latest movement stop timing is close to the latest movement stop timing of the own device 10.

  In the stop timing comparison, the in-vehicle determination unit 430 determines whether the difference between the latest movement stop timing of the other device 10 and the latest movement stop timing of the own device 10 is equal to or less than the first threshold value. Then, when determining that the difference is equal to or smaller than the first threshold, the in-vehicle determination unit 430 determines that the latest movement stop timing of the other device 10 and the latest movement stop timing of the own device 10 are close. On the other hand, when the in-vehicle determination unit 430 determines that the difference is larger than the first threshold, the latest movement stop timing of the other device 10 and the latest movement stop timing of the own device 10 are not close to each other. judge.

  In the present specification, as long as there is no inconsistency, a condition that a certain value is equal to or smaller than a threshold value can be replaced with a certain value that is smaller than the threshold value, and vice versa. Further, as long as there is no inconsistency, the fact that a certain value is equal to or greater than the threshold value can be replaced with the fact that the certain value is greater than the threshold value, and vice versa.

  In the above example, the in-vehicle determination unit 430 determines that both timings are close when the difference between the latest movement stop timing of the other device 10 and the latest movement stop timing of the own device 10 is equal to or less than the first threshold. Then, when the difference is larger than the first threshold value, it is determined that both timings are not close. When the above rule is applied, the in-vehicle determination unit 430 determines that the timing between the latest movement stop timing of the other device 10 and the latest movement stop timing of the own device 10 is smaller than the first threshold value. It may be determined that they are close to each other, and when the difference is equal to or greater than the first threshold, it may be determined that both timings are not close.

  In step s23, the in-vehicle determination unit 430 determines that the own user 9 is in the same vehicle 6 as the other user 9 when determining that the movement stop timing of the other device 10 is close to the movement stop timing of the own device 10. In step s24, it is determined that the user 9 exists in the vehicle. On the other hand, when the in-vehicle determination unit 430 determines that the movement stop timing of the other device 10 and the movement stop timing of the own device 10 are not close, in step s25, the in-vehicle determination unit 430 determines that the own user 9 does not exist in the vehicle. I do.

  Hereinafter, being determined to be “close” in the stop timing comparison means that both movement stop timings are determined to be close. Also, being determined as “not close” in the stop timing comparison means that it is determined that both movement stop timings are not close.

  Note that the in-vehicle determination unit 430 may perform the stop timing comparison a plurality of times in step s23. In this case, the in-vehicle determination unit 430 determines that the user 9 is present in the vehicle when determining “close” in each of the plurality of stop timing comparisons, and determines “close” in at least one of the plurality of stop timing comparisons. If it is determined that there is no user, it may be determined that the user 9 does not exist in the vehicle.

  When the in-vehicle determination unit 430 determines that the user 9 is inside the vehicle, the electronic device 10 starts moving each time the electronic device 10 starts moving, that is, starts moving. The timing may be notified to another electronic device 10 with which the electronic device 10 can communicate using Bluetooth or the like. In this case, in step s22, the in-vehicle determination unit 430 determines whether or not the movement start timing is notified from the other device 10. If it is determined in step s22 that the movement start timing is not notified from the other device 10, step s25 is executed, and it is determined that the user 9 is not present in the vehicle. On the other hand, when it is determined in step s22 that the movement start timing is notified from the other device 10, in step s23, the in-vehicle determination unit 430 is notified from the other device 10 that determines that the other user 9 is present in the vehicle. A start timing comparison is made to determine whether or not the latest movement start timing is close to the latest movement start timing of the own device 10. The in-vehicle determination unit 430 can identify the movement start timing of the own device 10 based on the result of the stop movement identification performed by the stop movement identification unit 410. The in-vehicle determination unit 430 determines whether or not both the movement start timings are close, for example, by comparing the difference between both the movement start timings and the second threshold value in the same manner as the stop timing comparison. be able to.

  In the start timing comparison, when it is determined that both the movement start timings are close, the in-vehicle determination unit 430 determines that the own user 9 is present in the same vehicle 6 as the other user 9 and executes step s24 to execute “s24”. It is determined that "in the car." On the other hand, when the in-vehicle determination unit 430 determines that both the movement start timings are not close, the in-vehicle determination unit 430 executes step s25 and determines “outside the vehicle”.

  Hereinafter, being determined as “close” in the start timing comparison means that both movement start timings are determined to be close. Also, being determined as “not close” in the start timing comparison means that it is determined that both movement start timings are not close.

  The in-vehicle determination unit 430 may perform the start timing comparison a plurality of times in step s23. In this case, the in-vehicle determination unit 430 determines “inside” when determining “close” in each of the plurality of start timing comparisons, and determines “not close” in at least one of the plurality of start timing comparisons. In this case, it may be determined that “outside the vehicle”.

  Also, when the in-vehicle determination unit 430 determines that the user 9 is in the vehicle, the electronic device 10 can communicate with the electronic device 10 using both the movement stop timing and the movement start timing as timing information. It may be notified to another electronic device 10 using Bluetooth or the like. In this case, in step s22, the in-vehicle determination unit 430 determines whether or not timing information is notified from the other device 10. When it is determined in step s22 that the timing information is not notified from the other device 10, step s25 is executed. On the other hand, when it is determined in step s22 that the timing information is notified from the other device 10, in step s23, the in-vehicle determination unit 430 performs both the stop timing comparison and the start timing comparison.

  In step s23, when performing both the stop timing comparison and the start timing comparison, the in-vehicle determination unit 430 determines, for example, “close” in the stop timing comparison and “close” in the start timing comparison. , "Inside the car". On the other hand, the in-vehicle determination unit 430 determines “outside the vehicle” when it determines “not close” in the stop timing comparison and when it determines “not close” in the start timing comparison.

  In step s23, the in-vehicle determination unit 430 may perform the stop timing comparison and the start timing comparison a plurality of times. In this case, the in-vehicle determination unit 430 determines “close” in each of the plurality of stop timing comparisons and determines “close” in each of the plurality of start timing comparisons. On the other hand, the in-vehicle determination unit 430 determines that “not close” in at least one of the plurality of stop timing comparisons, and determines “not close” in at least one of the plurality of start timing comparisons. It is determined as "outside the vehicle".

  In the above-described outside-of-vehicle determination, the movement stop timing or the movement start timing is used as the information indicating the movement of the electronic device 10, but the vibration of the electronic device 10 may be used. In this case, the in-vehicle determination unit 430 determines whether or not the own user 9 is present in the vehicle based on the vibration of the own device 10 and the vibration of the other device 10 that determines that the other user 9 is present in the vehicle. You may. In this example, the electronic device 10 that determines that the user 9 is present in the vehicle is, for example, a time change pattern of acceleration detected by the acceleration sensor 200 while the electronic device 10 is moving (hereinafter “moving time”). The electronic device 10 may communicate with other electronic devices 10 with which the electronic device 10 can communicate, using Bluetooth or the like. Then, in step s22, the in-vehicle determination unit 430 determines whether or not the other device 10 is notified of a moving acceleration pattern indicating the vibration of the other device 10. If it is determined in step s22 that the movement acceleration pattern is not notified from the other device 10, step s25 is executed. On the other hand, when it is determined in step s22 that the movement acceleration pattern is notified from the other device 10, the in-vehicle determination unit 430 determines in step s23 that the other user 9 determines that the other user 9 is present in the vehicle. A pattern comparison is performed in which the moving acceleration pattern is compared with a time change pattern (moving acceleration pattern) of the acceleration detected by the acceleration sensor 200 when the own device 10 is moving.

  Here, when the acceleration pattern at the time of movement of the other device 10 that determines that the other user 9 is present in the vehicle is similar to the acceleration pattern at the time of movement of the own device 10, the own user 9 is in the same vehicle 6 as the other user 9. It is likely to be in Therefore, in the pattern comparison, the in-vehicle determination unit 430 determines whether or not the moving acceleration pattern notified from the other device 10 that determines that the other user 9 is present in the vehicle is similar to the moving acceleration pattern of the own device 10. Is determined. If the in-vehicle determination unit 430 determines that both the acceleration patterns during movement are similar, the in-vehicle user 9 determines that the user 9 is present in the same vehicle 6 as the other user 9 and executes step s24 to determine “in-vehicle”. On the other hand, when the in-vehicle determination unit 430 determines that both the acceleration patterns during movement are not similar, the in-vehicle determination unit 430 performs step s25 and determines “outside the vehicle”. Whether or not the two moving acceleration patterns are similar can be determined, for example, based on the amplitude and cycle of the two moving acceleration patterns.

  Thus, the in-vehicle determination unit 430 determines whether the own user 9 is present in the vehicle based on the movement of the other device 10 that determines that the other user 9 is present in the vehicle and the movement of the own device 10. By doing so, even when the own user 9 gets on the vehicle 6 of another person, the electronic device 10 can correctly determine whether or not the own user 9 exists in the vehicle.

  Hereinafter, being determined as “similar” in the pattern comparison means that both moving acceleration patterns are determined to be similar. Further, being determined as “dissimilar” in the pattern comparison means that it is determined that both the acceleration patterns during movement are not similar.

  The in-vehicle determination unit 430 may determine whether or not the user 9 is present in the vehicle based on the acceleration pattern during movement and at least one of the movement stop timing and the movement start timing. In this case, for example, the in-vehicle determination unit 430 performs at least one of the stop timing comparison and the start timing comparison and the pattern comparison.

  When the stop timing comparison and the pattern comparison are performed, the in-vehicle determination unit 430 determines that the vehicle is in the vehicle if the stop timing comparison determines that the vehicle is close and the pattern comparison determines that the vehicle is similar. On the other hand, the in-vehicle determination unit 430 determines “outside the vehicle” when it determines “not close” in the stop timing comparison and when it determines “dissimilar” in the pattern comparison.

  When performing the start timing comparison and the pattern comparison, the in-vehicle determination unit 430 determines “close” when the start timing comparison is performed and determines “similar” in the pattern comparison. On the other hand, the in-vehicle determination unit 430 determines “outside the vehicle” when it determines “not close” in the start timing comparison and when it determines “dissimilar” in the pattern comparison.

  When performing the stop timing, the start timing comparison, and the pattern comparison, the in-vehicle determination unit 430 determines “close” in each of the stop timing comparison and the start timing comparison, and determines “similar” in the pattern comparison. It is determined that "in the car." On the other hand, the in-vehicle determination unit 430 determines when the stop timing is compared with “not close”, when the start timing is determined as “not close”, and when the pattern comparison is “dissimilar”. , "Outside the vehicle".

<Third example of in-vehicle determination: in-vehicle determination based on whether or not predetermined information is received>
As described in the “second example of the in-vehicle determination”, when the user 9 is not in the vehicle 6 owned by the user but in the vehicle 6 of another person, the electronic device 10 of the user 9 There is a possibility that the communication connection setting has not been made. Therefore, in the “first example of the in-vehicle determination”, when the user 9 exists in the vehicle 6 of another person, the in-vehicle determination unit 430 may not be able to appropriately determine that the user 9 is present in the vehicle.

  Therefore, in this example, the in-vehicle determination unit 430 determines whether or not the user 9 is present in the vehicle based on whether or not the wireless communication unit 110 receives the predetermined information transmitted from the on-vehicle communication device.

  For example, consider a case where device information transmitted by a communication device corresponding to at least one of Bluetooth and Wi-Fi includes maker information indicating the name of a manufacturer of the communication device. In this case, the in-vehicle determination unit 430 determines that the user 9 is present in the vehicle if the manufacturer information included in the device information received by the wireless communication unit 110 using Bluetooth or Wi-Fi indicates the vehicle manufacturer. That is, when the wireless communication unit 110 receives maker information indicating the automatic maker, the in-vehicle determination unit 430 determines that the user 9 is present in the vehicle. On the other hand, when the manufacturer information received by the wireless communication unit 110 using Bluetooth or Wi-Fi indicates a manufacturer other than the automobile manufacturer, the in-vehicle determination unit 430 determines that the user 9 does not exist in the vehicle. That is, when the wireless communication unit 110 does not receive the maker information indicating the vehicle maker, the in-vehicle determination unit 430 determines that the user 9 does not exist in the vehicle. In addition, the in-vehicle determination unit 430 may determine that the user 9 is present in the vehicle when the wireless communication unit 110 receives maker information indicating a car navigation device manufacturing company using Bluetooth or Wi-Fi. Further, the in-vehicle determination unit 430 may determine that the user 9 is present in the vehicle when the wireless communication unit 110 receives maker information indicating a car audio device manufacturing company using Bluetooth or Wi-Fi.

  Further, for example, a case is considered where the device information transmitted by the in-vehicle communication device includes in-vehicle information indicating that the device is a communication device mounted on the vehicle. In this case, in-vehicle determination section 430 determines that user 9 is present in the vehicle when wireless communication section 110 receives the in-vehicle information using Bluetooth or Wi-Fi. On the other hand, when the wireless communication unit 110 does not receive in-vehicle information using Bluetooth or Wi-Fi, the in-vehicle determination unit 430 determines that the user 9 does not exist in the vehicle.

  As described above, the in-vehicle determination unit 430 determines whether or not the user 9 is present in the vehicle based on whether or not the wireless communication unit 110 receives the predetermined information transmitted from the in-vehicle communication device. The electronic device 10 can correctly determine whether the user 9 is present in the vehicle even if the communication connection setting has not been made.

<Fourth example of in-vehicle determination: in-vehicle determination based on air condition around electronic device>
In this example, the in-vehicle determination unit 430 determines whether or not the user 9 is present in the vehicle based on the state of the air around the electronic device 10.

  As shown in FIG. 11, the electronic device 10 according to the present example includes a sensor 260 that detects a state of air around the electronic device 10. The sensor 260 is, for example, a gas sensor that detects a gas around the electronic device 10 as a state of air around the electronic device 10. In the in-vehicle determination, the in-vehicle determination unit 430 determines whether or not the user 9 is in the vehicle based on the detection result of the sensor 260. The type of gas sensor may be a semiconductor type or another type.

  Here, it is known that the gas component contained in the air inside the vehicle 6 and the gas component contained in the air outside the vehicle 6 are different from each other in terms of type and concentration. In this example, the detection result of the sensor 260 when the electronic device 10 is present in the vehicle 6 is stored in the storage unit 103 as vehicle gas information. It can be said that the vehicle gas information indicates the state of the air in the vehicle 6. The in-vehicle determination unit 430 acquires the detection result from the sensor 260 in the in-vehicle determination, and compares the acquired detection result with the vehicle gas information in the storage unit 103. Then, when the detection result of the sensor 260 and the vehicle gas information are similar, the in-vehicle determination unit 430 determines that the user 9 is present in the vehicle. On the other hand, when the detection result of the sensor 260 and the vehicle gas information are not similar, the in-vehicle determination unit 430 determines that the user 9 does not exist in the vehicle. Whether or not the detection result of the sensor 260 is similar to the vehicle gas information can be determined based on the type and concentration of the gas component contained therein.

  The operation mode of the electronic device 10 of the present example includes a gas information registration mode for registering vehicle gas information in the electronic device 10. When the electronic device 10 is present in the vehicle, the user 9 operates, for example, the display area 12 to cause the electronic device 10 to set the operation mode to the gas information registration mode. In the electronic device 10 in the gas information registration mode, when the user 9 performs a predetermined operation on the display area 12, for example, the detection result of the sensor 260 is stored in the storage unit 103 as vehicle gas information. Thereby, the vehicle gas information is registered in the electronic device 10. When the vehicle gas information is registered in the electronic device 10, the user 9 causes the electronic device 10 to release the gas information registration mode, for example, by operating the display area 12.

  The electronic device 10 may automatically register the vehicle gas information. For example, the control unit 100 registers, in the storage unit 103, the detection result of the sensor 260 when the moving means is specified as “vehicle” by the stop movement specifying unit 410 as vehicle gas information. When the user 9 is moving by “vehicle”, the control unit 100 may update the vehicle gas information in the storage unit 103 periodically or irregularly.

  Note that the sensor 260 may be an odor sensor that detects the odor around the electronic device 10 as the state of the air around the electronic device 10. In this case, in the in-vehicle determination, the in-vehicle determination unit 430 may determine whether or not the user 9 is in the vehicle based on whether or not the sensor 260 detects a specific odor. The specific smell includes, for example, the smell of a fragrance provided in a vehicle. In this example, the type of smell detected by the sensor 260 when the electronic device 10 is present in the vehicle is stored in the storage unit 103 as vehicle smell information. The in-vehicle determination unit 430 determines whether or not the type of odor detected by the sensor 260 matches the odor information in the storage unit 103 in the in-vehicle determination. The in-vehicle determination unit 430 determines that the user 9 is present in the vehicle when the type of the odor detected by the sensor 260 matches the odor information in the vehicle. On the other hand, if the type of odor detected by sensor 260 does not match the odor information in the vehicle, in-vehicle determination unit 430 determines that user 9 does not exist in the vehicle. The storage of the vehicle odor information in the storage unit 103, that is, the registration of the vehicle odor information in the electronic device 10, is performed by the user 9 operating the display area 12, similarly to the registration of the vehicle gas information in the electronic device 10. It may be performed by the electronic device 10 automatically.

  When a barcode indicating the type of odor contained in the fragrance provided in the vehicle is indicated in the fragrance, the type of odor indicated by the barcode is registered in the electronic device 10 as odor information in the vehicle. Is also good. The electronic device 10 can read information from the barcode and can store the read information in the storage unit 103 as vehicle information.

  As described above, the in-vehicle determination unit 430 determines whether or not the user 9 is present in the vehicle based on the state of the air around the electronic device 10, so that the user 9 is present in the vehicle. Can be determined more correctly.

<Fifth example of in-vehicle determination: in-vehicle determination based on type of user's means of transportation>
As shown in FIGS. 7 to 9 described above, when step s2 is not executed, the in-vehicle determination unit 430 determines whether the user 9 is based on the type of the moving means of the user 9 specified by the stop movement specifying unit 410. It may be determined whether the vehicle is present in the vehicle.

  For example, the in-vehicle determination unit 430 determines that the user 9 is present in the vehicle if the user 9 is determined to be a “vehicle” in the stop movement specification. On the other hand, the in-vehicle determination unit 430 determines that the user 9 determines that the moving means is “walking”, “running”, and “bicycle” in the stop movement specification. When it is determined, it is determined that the user 9 does not exist in the vehicle.

  As described above, the in-vehicle determining unit 430 determines whether or not the user 9 is present in the vehicle based on the type of the moving means of the user 9 specified by the stop movement specifying unit 410, so that the electronic device 10 It is possible to more correctly determine whether the user 9 is present in the vehicle.

  As described above, here, the five types of in-vehicle determination according to the first to fifth examples have been described. The in-vehicle determination unit 430 performs two or more types of in-vehicle determinations among the five types of in-vehicle determinations as provisional in-vehicle determinations in step s4 described above, and based on the result of the provisional in-vehicle determination, the user 9 May be finally determined.

  For example, the in-vehicle determination unit 430 determines that the user 9 is present in the vehicle when at least one of the two or more types of provisional in-vehicle determinations performed is determined to be “in-vehicle”. judge. Then, when all of the two or more types of provisional in-vehicle determinations performed are determined to be “outside the vehicle”, the in-vehicle determination unit 430 finally determines that the user 9 does not exist in the vehicle. When the in-vehicle determination unit 430 tentatively performs the in-vehicle determination according to the second and third examples, the in-vehicle determination unit 430 determines the movement of the other device 10 that determines that the other user 9 is present in the vehicle. It can be said that it is determined whether or not the user 9 is present in the vehicle based on the movement of the own device 10 and whether or not the wireless communication unit 110 of the own device 10 receives the predetermined information transmitted from the in-vehicle communication device. . When the in-vehicle determination unit 430 tentatively performs the in-vehicle determination according to the third and fourth examples, for example, the in-vehicle determination unit 430 determines whether the other user 9 determines that the other user 9 exists in the vehicle. It can be said that whether or not the user 9 is present in the vehicle is determined based on the movement of the own device 10 and the state of the air around the own device 10.

<Get off judgment>
The user 9 may get off the vehicle 6 and stay outside the vehicle while leaving the electronic device 10 in the vehicle 6. In such a case, since the electronic device 10 is present in the vehicle, the above-described in-vehicle determination may determine that the user 9 is present in the vehicle even though the user 9 is getting off the vehicle 6. .

  Therefore, even when the user 9 leaves the vehicle 6 with the electronic device 10 left in the vehicle, the electronic device 10 may be able to correctly determine that the user 9 has left the vehicle 6. . FIG. 12 is a block diagram illustrating an example of the configuration of the control unit 100 of the electronic device 10 in this case.

  As shown in FIG. 12, the control unit 100 includes an open / close specifying unit 600 that can specify whether the door of the vehicle 6 is open or closed. The state specifying unit 400 includes a getting-off specifying unit 460 that can specify that the user 9 has got off the vehicle 6. At least one of the opening / closing specifying unit 600 and the getting-off specifying unit 460 may be realized by a hardware circuit that does not require software to execute its function.

  The open / close specifying unit 600 can specify whether the door of the vehicle 6 is open or closed based on the vibration of the electronic device 10. The opening / closing specifying unit 600 can specify the opening / closing of the door of the vehicle 6 based on, for example, the acceleration that is detected by the acceleration sensor 200 and indicates the vibration of the electronic device 10.

  Here, when the door of the vehicle 6 is opened, the vehicle 6 vibrates. At this time, when the electronic device 10 exists in the vehicle 6, the electronic device 10 also vibrates. When the electronic device 10 vibrates, the acceleration detected by the acceleration sensor 200 also changes. Therefore, the opening / closing specifying unit 600 can specify that the door of the vehicle 6 has been opened based on the acceleration detected by the acceleration sensor 200.

  Similarly, when the door of the vehicle 6 is closed, the vehicle 6 vibrates. At this time, when the electronic device 10 exists in the vehicle 6, the electronic device 10 also vibrates. When the electronic device 10 vibrates, the acceleration detected by the acceleration sensor 200 also changes. Therefore, the opening / closing specifying unit 600 can specify that the door of the vehicle 6 is closed based on the acceleration detected by the acceleration sensor 200.

  When the in-vehicle determining unit 430 determines that the user 9 is present in the vehicle, the getting-off specifying unit 460 determines that the movement of the electronic device 10 has stopped by the stop / moving specifying unit 410, and then the opening / closing specifying unit 600 of the vehicle 6 uses When it is specified that the door is opened, and thereafter, when the opening / closing specifying unit 600 specifies that the door of the vehicle 6 is closed, it is determined that the user 9 has got off the vehicle 6. That is, the getting-off specifying unit 460 determines that the user 9 has got off the vehicle 6 when the movement of the electronic device 10 stops when the user 9 is present in the vehicle, and thereafter, the door of the vehicle 6 opens and then closes. Accordingly, even when the user 9 gets off the vehicle 6 with the electronic device 10 left in the vehicle, the electronic device 10 can correctly specify that the user 9 got off the vehicle 6.

  When the getting-off specifying unit 460 determines that the user 9 has got off the vehicle 6 and the electronic device 10 is located in the predetermined area, the notification determination unit 500 determines “notification execution”. On the other hand, even when it is determined that the user 9 has got off the vehicle 6 by the getting-off specifying unit 460, if the electronic device 10 is not located in the predetermined area, the notification determination unit 500 performs “notification not executed”. decide. Regardless of whether or not the electronic device 10 is located in the predetermined area, when the getting-off specifying unit 460 determines that the user 9 has got off the vehicle 6, the notification determining unit 500 may determine “execute notification”. Good.

  Also, when the in-vehicle determination unit 430 determines that the user 9 is present in the vehicle, the getting-off determination unit 460 determines that the movement of the electronic device 10 has stopped by the stop / movement determination unit 410, and then the opening / closing determination unit 600 specifies the vehicle 6. May be determined that the user 9 has got off the vehicle 6. In this case, the opening / closing specifying unit 600 does not need to specify that the door of the vehicle 6 is closed.

  Also, when the in-vehicle determination unit 430 determines that the user 9 is present in the vehicle, the getting-off determination unit 460 determines that the movement of the electronic device 10 has stopped by the stop / movement determination unit 410, and then the opening / closing determination unit 600 specifies the vehicle 6. May be determined that the user 9 has got off the vehicle 6. In this case, the opening / closing specifying unit 600 does not need to specify that the door of the vehicle 6 is opened.

  As described above, in this example, when it is determined that the user 9 is present in the vehicle, it is determined that the movement of the electronic device 10 has stopped, and then at least one of the opening and closing of the door of the vehicle 6 is performed. When specified, the getting-off specifying unit 460 determines that the user 9 has got off the vehicle. In other words, when the state of the electronic device 10 changes from the moving state to the stopped state when the user 9 is present in the vehicle, and when at least one of the opening and closing of the door of the vehicle 6 is specified, the user The getting-off specifying unit 460 determines that the vehicle 9 has got off the vehicle. Thereby, the electronic device 10 can correctly specify that the user 9 gets off the vehicle 6.

  Even when the user 9 gets off the vehicle 6 with the electronic device 10, the electronic device 10 held by the user 9 is likely to vibrate when the door of the vehicle 6 opens and closes. Therefore, even when the user 9 gets off the vehicle 6 with the electronic device 10, the getting-off specifying unit 460 can correctly specify that the user 9 got off the vehicle 6.

  In addition, when the user 9 moves down by himself with the electronic device 10 from the vehicle 6, the stop movement specifying unit 410 of the electronic device 10 specifies that the user 9 moves by itself. Then, the drop-off specifying unit 460 determines that the movement of the electronic device 10 has stopped when the user 9 is determined to be present in the vehicle, and then specifies that the stop movement specifying unit 410 specifies that the user 9 moves by itself. Alternatively, it may be determined that the user 9 has got off the vehicle 6. Thereby, when the user 9 gets off the vehicle 6 with the electronic device 10, it is possible to more correctly specify that the user 9 got off the vehicle 6.

  In addition, when the vehicle 6 can notify the electronic device 10 in the vehicle 6 of the opening / closing information on the own door using Bluetooth or the like, the getting-off specifying unit 460 opens and closes the door from the vehicle 6. You may specify that the user 9 got off the vehicle 6 based on information. For example, when it is determined that the user 9 is present in the vehicle, the getting-off specifying unit 460 determines that the movement of the electronic device 10 has stopped, and then notifies the vehicle 6 that the door of the vehicle 6 has been opened. Alternatively, it may be determined that the user 9 has got off the vehicle 6. Also, when it is determined that the user 9 is present in the vehicle, the getting-off specifying unit 460 determines that the movement of the electronic device 10 has stopped, and then notifies the vehicle 6 that the door of the vehicle 6 is closed. It may be determined that the user 9 has got off the vehicle 6. Also, when it is determined that the user 9 is present in the vehicle, the getting-off specifying unit 460 is notified by the vehicle 6 that the door of the vehicle 6 has been opened after it is specified that the movement of the electronic device 10 has stopped. When the vehicle 6 is notified that the door of the vehicle 6 is closed, it may be determined that the user 9 has got off the vehicle 6.

  As described above, when it is determined that the user 9 is present in the vehicle, and it is determined that the movement of the electronic device 10 has stopped, the vehicle 6 notifies that at least one of the opening and closing of the door has been performed. By determining that the user 9 has got off the vehicle 6 by the getting-off specifying unit 460, the electronic device 10 can correctly specify that the user 9 gets off the vehicle 6.

<Indoor judgment>
Next, details of the indoor determination will be described. Hereinafter, examples of a plurality of types of indoor determination will be described.

<First Example of Indoor Judgment: Using Change in Reception State and User Movement>
When the user 9 moves from outdoors to indoors, there is a high possibility that the reception state of the receiver 140 deteriorates. Further, when the user 9 moves from indoor to outdoor, the reception state of the receiving unit 140 is likely to be improved. Therefore, it is possible to determine to some extent accurately whether or not the user 9 is indoors based on a change in the reception state of the reception unit 140.

  However, even when the user 9 is outdoors, when the user 9 temporarily passes under a tunnel or a bridge, or when there is a temporary eave above the user 9, the receiving unit The receiving state of 140 may change. Therefore, when it is determined whether or not the user 9 is indoors based only on a change in the reception state of the receiving unit 140, an erroneous determination may occur.

  Therefore, the indoor determination unit 440 according to the present example sets the user 9 indoors based on the change in the reception state of the reception unit 140 and the motion information indicating the motion of the user 9 acquired by the motion information acquisition unit 420. Determine if it exists. Thereby, it can be more correctly determined whether or not the electronic device 10 user 9 exists indoors.

  The motion information includes at least one of the continuous stop time of the user 9, the continuous walking time of the user 9, the number of continuous walking steps of the user 9, and the traveling direction of the user 9. Here, the continuous stop time of the user 9 is a time during which the user 9 is continuously stopped. The continuous walking time of the user 9 is a time during which the user 9 is continuously walking. Further, the number of continuous walking steps of the user is the number of steps from the start of walking when the user 9 is walking continuously. Hereinafter, the indoor determination based on the continuous stop time of the user 9, the indoor determination based on the continuous walking time of the user 9, the indoor determination based on the number of continuous walking steps of the user 9, and the indoor determination based on the traveling direction of the user 9 will be described. I do. Hereinafter, simply the receiving state means the receiving state of the receiving unit 140.

<Indoor judgment based on the user's continuous stop time>
When the user 9 exists indoors, the user 9 is likely to stop continuously for a long time. Therefore, the indoor determination unit 440 determines whether the user 9 is indoors based on, for example, a change in the reception state and the continuous stop time of the user 9. FIG. 13 is a flowchart showing an example of the indoor determination in this case.

  As shown in FIG. 13, in step s31, the indoor determining unit 440 checks the result of the previous indoor determination. If the indoor determination unit 440 determines “outdoor” in the previous indoor determination, that is, if it determines that the user 9 is present outdoors, in step s32, it is determined whether the reception state deteriorates during a predetermined time. Is determined. If the indoor determination unit 440 determines that the reception state has deteriorated during the predetermined time, in step s33, the indoor determination unit 440 determines whether the continuous stop time of the user 9 is equal to or more than the third threshold value in the state where the reception state is deteriorated. Check (monitor) for a predetermined time. On the other hand, when determining that the reception state does not deteriorate during the predetermined time, the indoor determination unit 440 determines that the user 9 does not exist indoors in step s36.

  In step s33, the indoor determination unit 440 determines that the continuous stop time of the user 9 is equal to or more than the third threshold value during a predetermined time period in a state where the reception state is deteriorated. Is determined. On the other hand, if it is not possible to confirm within a predetermined time that the continuous stop time of the user 9 is equal to or longer than the third threshold value in a state where the reception state is deteriorated, the indoor determination unit 440 determines “outdoor Is determined.

  The third threshold value is set to, for example, 10 seconds or more. The indoor determination unit 440 can determine the continuous stop time of the user 9 based on the result of the stop movement identification performed by the stop movement identification unit 410.

  The indoor determination unit 440 determines that, for example, the latest captured satellite number acquired by the receiving unit 140 is smaller than the previously acquired captured satellite number, and the absolute value of the difference between the two acquired satellite numbers is equal to the fourth threshold value. At this time, it is determined that the reception state has deteriorated. The fourth threshold value is set to, for example, 3 or more. Note that, instead of the number of captured satellites, a C / N value of a signal received by the receiving unit 140 may be employed. The C / N value indicates the ratio between the carrier power and the noise power, and indicates the reception quality. Receiving section 140 can calculate the C / N value of the received signal and output it to control section 100. The indoor determination unit 440 determines that the latest C / N value acquired by the receiving unit 140 is smaller than the previously acquired C / N value, and the absolute value of the difference between the two C / N values is the fifth threshold. When the value is equal to or more than the value, it is determined that the reception state has deteriorated. The fifth threshold value is set to, for example, 10 or more.

  In step s31, the indoor determination unit 440 checks the result of the previous indoor determination, determines that the indoor determination is “indoor” in the previous indoor determination, that is, determines that the user 9 exists indoors. Confirms in step s35 whether the reception state improves during a predetermined time. When determining that the reception state has improved during the predetermined time, the indoor determination unit 440 determines “outdoor” in step s36. On the other hand, when it is not possible to confirm that the reception state has improved during the predetermined time, that is, when the reception state has not improved during the predetermined time, the indoor determination unit 440 determines “indoor” in step s34. judge.

  The indoor determination unit 440 determines that, for example, the latest captured satellite number acquired by the receiving unit 140 is larger than the previously acquired captured satellite number, and the absolute value of the difference between the two acquired satellite numbers is equal to the sixth threshold value. At this time, it is determined that the reception state has been improved. The sixth threshold value is set to, for example, 3 or more. Note that, instead of the number of captured satellites, a C / N value of a signal received by the receiving unit 140 may be employed.

  As described above, the indoor determination unit 440 determines whether or not the user 9 is indoors based on the change in the reception state and the continuous stop time of the user 9, so that the electronic device 10 It can be more correctly determined whether or not exists indoors.

  Hereinafter, checking for a predetermined time whether the continuous stop time of the user 9 is equal to or more than the third threshold value in a state in which the reception state is deteriorated may be referred to as “confirmation of the stop time in the deteriorated state”. . In addition, when it is said that “stop time / large” has been confirmed in the stop time confirmation in the deteriorated state, it is determined that the continuous stop time of the user 9 is equal to or more than the third threshold value in the state in which the reception state is deteriorated. Means that it was confirmed during the time. In addition, if the "stop time / large" is not confirmed in the stop time confirmation in the deteriorated state, the continuous stop time of the user 9 may be equal to or more than the third threshold value in the state in which the reception state is deteriorated. It means that it was not confirmed within a predetermined time.

<Indoor judgment based on the user's continuous walking time>
When the user 9 is indoors, the possibility that the continuous walking time of the user 9 is long is low. Therefore, the indoor determination unit 440 determines whether the user 9 is indoors based on, for example, a change in the reception state and the continuous walking time of the user 9. In this case, the indoor determination unit 440 confirms in the above-described step s33 whether or not the continuous walking time of the user 9 in the state where the reception state is deteriorated is equal to or longer than the seventh threshold for a predetermined time. If the indoor determination unit 440 can confirm that the continuous walking time of the user 9 in the state in which the reception state is deteriorated becomes equal to or greater than the seventh threshold value during the predetermined time, the indoor determination unit 440 executes step s36 to perform “outdoor”. Is determined. On the other hand, if it is not confirmed during the predetermined time that the continuous walking time of the user 9 in the state where the reception state is deteriorated becomes equal to or more than the seventh threshold value, the indoor determination unit 440 executes step s34. Is determined as “indoor”. The seventh threshold is set to, for example, 5 to 10 seconds. The indoor determination unit 440 can determine the continuous walking time of the user 9 based on the result of the stop movement identification performed by the stop movement identification unit 410. Other portions of the indoor determination of this example are the same as in the example of FIG.

  As described above, the indoor determination unit 440 determines whether the user 9 is indoors based on the change in the reception state and the continuous walking time of the user 9, so that the electronic device 10 It can be more correctly determined whether or not exists indoors.

  Hereinafter, checking for a predetermined time whether the continuous walking time of the user 9 is equal to or more than the seventh threshold value in a state in which the reception state is deteriorated may be referred to as “confirmation of the walking time in the deteriorated state”. . In addition, when it is said that “walking time / large” is confirmed in the walking time confirmation in the deteriorated state, it is determined that the continuous walking time of the user 9 is equal to or more than the seventh threshold value in the state in which the reception state is deteriorated. Means that it was confirmed during the time. In addition, if it is said that “walking time / large” was not confirmed in the walking time confirmation in the deteriorated state, the continuous walking time of the user 9 may be equal to or more than the seventh threshold value in the state in which the reception state is deteriorated. It means that it was not confirmed within a predetermined time.

<Indoor judgment based on the number of continuous walking steps of the user>
When the user 9 exists indoors, the possibility that the number of continuous walking steps of the user 9 is large is low. Thus, the indoor determination unit 440 determines whether the user 9 is indoors based on, for example, a change in the reception state and the number of continuous walking steps of the user 9. In this case, in step s33, the indoor determination unit 440 checks whether the number of continuous walking steps of the user 9 in the state where the reception state is deteriorated is equal to or larger than the eighth threshold for a predetermined time. If the indoor determination unit 440 can confirm that the number of continuous walking steps of the user 9 in the state where the reception state is deteriorated becomes equal to or greater than the eighth threshold value during the predetermined time, the indoor determination unit 440 executes step s36 to perform “outdoor”. Is determined. On the other hand, if the indoor determination unit 440 cannot confirm during the predetermined time that the number of continuous walking steps of the user 9 becomes equal to or larger than the eighth threshold value in the state where the reception state is deteriorated, the indoor determination unit 440 executes step s34. Is determined as “indoor”. The eighth threshold value is set to, for example, 5 to 10. The indoor determination unit 440 can obtain the number of continuous walking steps of the user 9 based on the result of the stop movement identification performed by the stop movement identification unit 410. Other portions of the indoor determination of this example are the same as in the example of FIG.

  As described above, the indoor determination unit 440 determines whether or not the user 9 is indoors based on the change in the reception state and the number of continuous walking steps of the user 9, so that the electronic device 10 It can be more correctly determined whether or not exists indoors.

  Hereinafter, checking for a predetermined time whether the number of continuous walking steps of the user 9 is equal to or more than the eighth threshold value in a state where the reception state is deteriorated may be referred to as “confirmation of the number of steps in the deteriorated state”. In addition, when it is said that “the number of steps / large” is confirmed in the step number confirmation in the deteriorated state, it is determined that the continuous walking step number of the user 9 becomes equal to or larger than the eighth threshold value in the state in which the reception state is deteriorated for a predetermined time. It means that it was confirmed in the meantime. In addition, if it is said that “the number of steps / large” is not confirmed in the step number confirmation in the deteriorated state, it is determined that the number of continuous walking steps of the user 9 becomes equal to or more than the eighth threshold value in the state in which the reception state is deteriorated. Means not confirmed during

<Indoor judgment based on user's traveling direction>
When the user 9 is indoors, the possibility that the traveling direction of the user 9 is constant for a long time is low. Therefore, the indoor determination unit 440 determines whether the user 9 is indoors based on, for example, a change in the reception state and the traveling direction of the user 9. In this case, the indoor determination unit 440 checks whether the traveling direction of the user 9 does not change for the predetermined time in the above-described step s33 while the reception state is deteriorated. The indoor determination unit 440 can specify the traveling direction of the user 9 based on the magnetic field detected by the geomagnetic sensor 230. If the indoor determination unit 440 determines that the traveling direction of the user 9 does not change during the predetermined time while the reception state is deteriorated, the indoor determination unit 440 performs step s36 and determines “outdoor”. On the other hand, if the indoor determination unit 440 determines that the traveling direction of the user 9 has changed during the predetermined time while the reception state is deteriorated, the indoor determination unit 440 performs step s34 and determines “indoor”. Other portions of the indoor determination of this example are the same as in the example of FIG.

  As described above, the indoor determination unit 440 determines whether the user 9 is indoors based on the change in the reception state and the traveling direction of the user 9, so that the electronic device 10 can determine whether the user 9 is present. It is possible to more correctly determine whether or not the vehicle exists indoors.

  Hereinafter, checking whether the traveling direction of the user 9 does not change for a predetermined time while the reception state is deteriorated may be referred to as “confirmation of the traveling direction in a deteriorated state”. In addition, it can be said that “no change” is confirmed in the traveling direction confirmation in the deteriorated state, which means that it is determined that the traveling direction of the user 9 does not change during the predetermined time while the reception state is deteriorated. I do. In addition, when it is said that “no change” is not confirmed in the traveling direction confirmation in the deteriorated state, it is determined that the traveling direction of the user 9 has changed during the predetermined time while the reception state is deteriorated. means.

  The indoor determination unit 440 determines the user's continuous stop time, the user's 9 continuous walking time, the user's 9 continuous walking steps, at least two pieces of information on the user's 9 traveling direction, and the change in the reception state. It may be determined whether or not 9 exists indoors.

  For example, in step s33, the indoor determination unit 440 performs the stop time confirmation in the deteriorated state and the walking time confirmation in the deteriorated state, and thereby the continuous stop time and the continuous walking time of the user 9 and the change in the reception state. Based on this, it may be determined whether or not the user 9 exists indoors. In this case, the indoor determination unit 440 determines that “stop time / large” is confirmed in the stop time confirmation in the deteriorated state, and “walk time / large” is not confirmed in the walk time confirmation in the deteriorated state. Is determined to be “indoor”. On the other hand, the indoor determination unit 440 determines that “stop time / large” is not confirmed in the stop time confirmation in the deteriorated state, and that “walking time / large” is confirmed in the walk time confirmation in the deteriorated state. Is determined to be “outdoor”.

  In addition, for example, in step s33, the indoor determination unit 440 confirms the stop time in the deteriorated state, the walking time in the deteriorated state, and the number of steps in the deteriorated state, and thereby the continuous stop time and the continuous walking time of the user 9. Alternatively, it may be determined whether or not the user 9 is indoors based on the number of continuous walking steps and the change in the reception state. In this case, the indoor determination unit 440 determines that “stop time / large” is confirmed in the stop time confirmation in the deteriorated state, and “walk time / large” is not confirmed in the walk time confirmation in the deteriorated state, and If “step count / large” is not confirmed in the step count confirmation in the deteriorated state, it is determined to be “indoor”. On the other hand, the indoor determination unit 440 determines that “stop time / large” is not confirmed in the stop time confirmation in the deteriorated state, and that “walking time / large” is confirmed in the walk time confirmation in the deteriorated state. If "step count / large" is confirmed in the step count check in the deteriorated state, it is determined that "outdoors".

  Further, for example, in step s33, the indoor determination unit 440 checks the stop time in the deteriorated state, checks the walking time in the deteriorated state, checks the number of steps in the deteriorated state, and checks the traveling direction in the deteriorated state. It may be determined whether or not the user 9 is indoors based on the continuous stop time, the continuous walking time, the number of continuous walking steps, the traveling direction, and the change in the reception state. In this case, the indoor determination unit 440 determines that “stop time / large” is confirmed in the stop time confirmation in the deteriorated state, and “walk time / large” is not confirmed in the walk time confirmation in the deteriorated state, and If “step count / large” is not confirmed in the step count confirmation in the deteriorated state and “no change” is not confirmed in the traveling direction check in the deteriorated state, it is determined to be “indoor”. On the other hand, the indoor determination unit 440 determines that “stop time / large” is not confirmed in the stop time confirmation in the deteriorated state, and that “walking time / large” is confirmed in the walk time confirmation in the deteriorated state. In the case where "step count / large" is confirmed in the step count confirmation in the deteriorated state, and when "no change" is confirmed in the traveling direction check in the deteriorated state, it is determined to be "outdoor".

  In addition, even when the user 9 is indoors, the reception state may be improved when the user 9 is located near the window. Accordingly, as in the example of FIG. 13 described above, when the indoor determination unit 440 determines that the user 9 exists indoors, and then determines that the reception state has improved, and determines that the user 9 is “outdoor”, the user 9 There is a possibility that it is determined that the user 9 does not exist indoors even though the user 9 exists indoors.

  On the other hand, when the user 9 is indoors, even if the reception state is improved, the possibility that the continuous stop time of the user 9 is long and the possibility that the continuous walking time of the user 9 is not long are not changed.

  Therefore, if the indoor determination unit 440 determines that the reception state has been improved after determining that the user 9 is indoors, the indoor determination unit 440 may specify that the user 9 has gone outdoors based on the motion information.

  For example, after determining that the reception state has been improved during the predetermined time in step s35, the indoor determination unit 440 executes step s38 as shown in FIG. In step s38, the indoor determination unit 440 determines whether the user 9 has gone outdoors based on the motion information. In step s38, the indoor determination unit 440 determines whether the user 9 has gone outdoors, for example, based on the continuous stop time of the user 9. The indoor determination unit 440, for example, checks whether the continuous stop time of the user 9 is equal to or longer than the third threshold value in a state where the reception state is improving for a predetermined time. Hereinafter, this confirmation may be referred to as “confirmation of the stop time in the improved state”. The indoor determination unit 440 determines that the user 9 has gone outdoors if the continuous stop time of the user 9 cannot be confirmed to be equal to or more than the third threshold value during the predetermined time while the reception state is improving. judge. Then, the indoor determining unit 440 executes step s36 to determine “outdoor”. On the other hand, the indoor determination unit 440 determines that if the continuous stop time of the user 9 is equal to or more than the third threshold value during the predetermined time in a state where the reception state is improved, the user 9 goes outdoors. It is determined that it has not come out. Then, the indoor determining unit 440 executes step s34 to determine “indoor”.

  Thereafter, when it is said that “stop time / large” has been confirmed in the stop time confirmation in the improved state, it is determined that the continuous stop time of the user 9 becomes equal to or more than the third threshold value in the state in which the reception state is improved. Means that it was confirmed during the time. In addition, if the "stop time / large" is not confirmed in the stop time confirmation in the improved state, the continuous stop time of the user 9 may be equal to or more than the third threshold value in the state in which the reception state is improved. It means that it was not confirmed within a predetermined time.

  In step s38, the indoor determination unit 440 may determine whether the user 9 has gone outdoors based on the continuous walking time of the user 9. In this case, for example, the indoor determination unit 440 checks for a predetermined time whether the continuous walking time of the user 9 is equal to or greater than the seventh threshold value in a state where the reception state is improving. This confirmation may be referred to as “confirmation of walking time in the improved state”. The indoor determination unit 440 determines that the user 9 has gone outdoors if the continuous walking time of the user 9 can be confirmed to be equal to or longer than the seventh threshold value in a state where the reception state is improved during the predetermined time. On the other hand, if the indoor determination unit 440 cannot confirm during the predetermined time that the continuous walking time of the user 9 becomes equal to or greater than the seventh threshold value in a state where the reception state is improved, the user 9 goes outdoors. It is determined that it has not come out.

  Thereafter, if it is said that "walking time / large" has been confirmed in the walking time confirmation in the improved state, it is determined that the continuous walking time of the user 9 becomes equal to or more than the seventh threshold value in the state in which the receiving state is improved. Means that it was confirmed during the time. Also, if it is said that “walking time / large” was not confirmed in the walking time confirmation in the improved state, the continuous walking time of the user 9 may be equal to or more than the seventh threshold value in the state in which the receiving state is improved. It means that it was not confirmed within a predetermined time.

  Further, in step s38, the indoor determination unit 440 may determine whether the user 9 has gone outdoors based on the number of continuous walking steps of the user 9. In this case, for example, the indoor determination unit 440 checks for a predetermined time whether the number of continuous walking steps of the user 9 is equal to or more than the eighth threshold value in a state where the reception state is improving. This confirmation may be referred to as “confirmation of the number of steps in the improved state”. The indoor determination unit 440 determines that the user 9 has gone outdoors if the number of continuous walking steps of the user 9 can be confirmed to be equal to or more than the eighth threshold value during the predetermined time in a state where the reception state is improved. On the other hand, if the indoor determination unit 440 cannot confirm during the predetermined time that the number of continuous walking steps of the user 9 becomes equal to or more than the eighth threshold value in a state in which the reception state is improved, the user 9 goes outdoors. It is determined that it has not come out.

  Thereafter, if it can be said that “the number of steps / large” is confirmed in the step number confirmation in the improved state, it is determined that the number of continuous walking steps of the user 9 becomes equal to or more than the eighth threshold value in the state in which the reception state is improved for a predetermined time. It means that it was confirmed in the meantime. In addition, if it can be said that “the number of steps / large” was not confirmed in the confirmation of the number of steps in the improved state, it is determined that the number of continuous walking steps of the user 9 becomes equal to or more than the eighth threshold value in the state in which the reception state is improved. Means not confirmed during

  Further, in step s38, the indoor determination unit 440 may determine whether the user 9 has gone outdoors based on the traveling direction of the user 9. In this case, for example, the indoor determination unit 440 checks whether the traveling direction of the user 9 does not change for a predetermined time while the reception state is improving. This confirmation may be referred to as “confirmation of the traveling direction in the improved state”. When the indoor determination unit 440 determines that the traveling direction of the user 9 does not change for the predetermined time while the reception state is improving, it determines that the user 9 is not outside. On the other hand, when it is determined that the traveling direction of the user 9 has changed during the predetermined time while the reception state is improving, the indoor determination unit 440 determines that the user 9 has gone outdoors.

  Thereafter, when "no change" is confirmed in the confirmation of the traveling direction in the improved state, it means that it is determined that the traveling direction of the user 9 does not change during the predetermined time while the reception state is improved. I do. Also, if it is said that “no change” was not confirmed in the traveling direction confirmation in the improved state, it means that it was determined that the traveling direction of the user 9 changed during the predetermined time in the state in which the receiving state was improved. means.

  In step s38, the indoor determination unit 440 determines whether the user 9 is outdoors based on at least two pieces of information on the continuous stop time of the user 9, the continuous walking time of the user 9, the number of continuous walking steps of the user 9, and the traveling direction of the user 9. It may be determined whether or not the vehicle has left.

  For example, in step s38, the indoor determination unit 440 performs the stop time check in the improved state and the walk time check in the improved state, and based on the continuous stop time and the continuous walk time of the user 9, the user 9 May be determined. In this case, the indoor determination unit 440 determines that “stop time / large” is confirmed in the stop time confirmation in the improved state, and “walk time / large” is not confirmed in the walk time confirmation in the improved state. It is determined that the user 9 is not outside. On the other hand, the indoor determination unit 440 determines that “stop time / large” is not confirmed in the stop time confirmation in the improved state, and that “walking time / large” is confirmed in the walk time confirmation in the enhanced state. It is determined that the user 9 has gone outdoors.

  In addition, for example, in step s38, the indoor determination unit 440 checks the stop time in the improved state, the walking time in the improved state, and the number of steps in the improved state, so that the user 9 has the continuous stop time and the continuous walking time. It may be determined whether or not the user 9 has gone outdoors based on the number of continuous walking steps. In this case, the indoor determination unit 440 determines that “stop time / large” is confirmed in the stop time confirmation in the improved state, and “walk time / large” is not confirmed in the walk time confirmation in the improved state, and If "step count / large" is not confirmed in the step count confirmation in the improved state, it is determined that the user 9 is not out of the outdoors. On the other hand, the indoor determination unit 440 determines that “stop time / large” is not confirmed in the stop time confirmation in the improved state, and that “walking time / large” is confirmed in the walk time confirmation in the enhanced state. When the number of steps is large in the step count check in the improved state, it is determined that the user 9 has gone outdoors.

  Further, for example, in step s38, the indoor determination unit 440 performs the confirmation of the stop time in the improved state, the confirmation of the walking time in the improved state, the confirmation of the number of steps in the improved state, and the confirmation of the traveling direction in the improved state. May be determined based on the continuous stop time, the continuous walking time, the number of continuous walking steps, and the traveling direction of the user 9. In this case, the indoor determination unit 440 determines that “stop time / large” is confirmed in the stop time confirmation in the improved state, and “walk time / large” is not confirmed in the walk time confirmation in the improved state, and If "step count / large" is not confirmed in the step count confirmation in the improved state and "no change" is not confirmed in the traveling direction check in the improved state, it is determined that the user 9 is not out of the outdoors. . On the other hand, the indoor determination unit 440 determines that “stop time / large” is not confirmed in the stop time confirmation in the improved state, and that “walking time / large” is confirmed in the walk time confirmation in the enhanced state. When it is confirmed that "the number of steps is large" in the confirmation of the number of steps in the improved state, and when "no change" is confirmed in the confirmation of the traveling direction in the improved state, it is determined that the user 9 has gone outdoors. .

  As described above, when the indoor determination unit 440 determines that the reception state has been improved after determining that the user 9 is present indoors, the indoor determination unit 440 specifies that the user 9 has gone outdoors based on the motion information. The electronic device 10 can more correctly specify that the user 9 has gone outdoors.

<Second example of indoor determination: using change in reception state and change in height of position of electronic device>
When the user 9 is located indoors, the user 9 moves from the first floor to the second floor or moves from the first floor to the basement, so that the height of the position of the electronic device 10 is likely to change.

  Therefore, indoor determination section 440 may determine whether user 9 is indoors based on a change in the height of the position of electronic device 10 and a change in the reception state.

  In this example, in step s33 described above, for example, the indoor determination unit 440 checks for a predetermined time whether the height of the position of the electronic device 10 has increased by a predetermined value or more in a state where the reception state has deteriorated. In addition, the indoor determination unit 440 checks for a predetermined time whether the height of the position of the electronic device 10 has decreased by a predetermined value or more in a state where the reception state has deteriorated. The indoor determination unit 440 can determine whether the height of the position of the electronic device 10 has increased by a predetermined value or more based on the detection result of the atmospheric pressure sensor 210. In addition, the indoor determination unit 440 can determine whether the height of the position of the electronic device 10 has decreased by a predetermined value or more based on the detection result of the atmospheric pressure sensor 210.

  When the indoor determination unit 440 confirms during a predetermined time that the height of the position of the electronic device 10 increases by a predetermined value or more in a state where the reception state is deteriorated, the indoor determination unit 440 performs step s34 and determines that the room is “indoor”. I do. When the indoor determination unit 440 confirms during a predetermined time that the height of the position of the electronic device 10 decreases by a predetermined value or more in a state in which the reception state is deteriorated, the process proceeds to step s34 and changes to “indoor”. judge. On the other hand, the indoor determination unit 440 cannot confirm within a predetermined time that the height of the position of the electronic device 10 has increased by a predetermined value or more in a state where the reception state has deteriorated, and the reception state has deteriorated. If it is not possible to confirm during the predetermined time that the height of the position of the electronic device 10 has decreased by the predetermined value or more in the state where the electronic device 10 is present, step s36 is executed and it is determined that “outdoor”.

  As described above, the indoor determination unit 440 determines whether the user 9 is indoors based on the change in the height of the position of the electronic device 10 and the change in the reception state. Can more correctly determine whether the user 9 exists indoors.

  Note that in step s38 of FIG. 14 described above, the indoor determination unit 440 may determine whether the user 9 has gone outdoors based on a change in the height of the position of the electronic device 10. In this case, the indoor determination unit 440 checks for a predetermined time whether the height of the position of the electronic device 10 increases by a predetermined value or more while the reception state is improving. Further, the indoor determination unit 440 checks for a predetermined time whether the height of the position of the electronic device 10 decreases by a predetermined value or more in a state where the reception state is improving. When the indoor determination unit 440 confirms that the height of the position of the electronic device 10 increases by a predetermined value or more during a predetermined time in a state where the reception state is improving, it determines that the user 9 is not outdoors. . When the indoor determination unit 440 confirms during a predetermined time that the height of the position of the electronic device 10 decreases by a predetermined value or more in a state where the reception state is improved, the indoor determination unit 440 determines that the user 9 is not outdoors. I do. On the other hand, the indoor determination unit 440 cannot confirm during a predetermined time that the height of the position of the electronic device 10 increases by a predetermined value or more in a state where the reception state is improving, and the reception state is improved. If it is not possible to confirm during the predetermined time that the height of the position of the electronic device 10 decreases by a predetermined value or more in the state where the user is present, it is determined that the user 9 has gone outdoors.

  Thus, after the indoor determination unit 440 determines that the user 9 is indoors, the user 9 goes outdoors based on the change in the height of the position of the electronic device 10 and the change in the reception state. By specifying, the electronic device 10 can more correctly specify that the user 9 has left the outdoors.

<Third example of indoor determination: using change in reception state and change in state around electronic device>
When the user 9 moves from outdoors to indoors, there is a high possibility that the state around the electronic device 10 changes. When the user 9 moves from outdoors to indoors, for example, the temperature around the electronic device 10 is likely to change. Also, when the user 9 moves from outdoors to indoors, the magnetic field around the electronic device 10 is likely to change. Further, when the user 9 moves from outdoors to indoors, there is a high possibility that the state of air around the electronic device 10 changes.

  Therefore, the indoor determination unit 440 may determine whether the user 9 is indoors based on a change in the surrounding state of the electronic device 10 and a change in the reception state. The indoor determination unit 440 determines whether or not the user 9 is present indoors, for example, based on at least one change in the temperature, magnetic field, and air state around the electronic device 10 and a change in the reception state. You may.

  FIG. 15 is a flowchart illustrating an example of the indoor determination according to the present example. In the flowchart of FIG. 15, step s41 is executed instead of steps s32 and s33 in the flowchart of FIG.

  As shown in FIG. 15, in step s31, when it is determined that “outdoor” in the previous indoor determination, in step s41, the indoor determination unit 440 changes the state around the electronic device 10 and the reception state. It is determined whether or not the user 9 is indoors based on the change of the user 9. In step s41, for example, the indoor determination unit 440 determines whether the reception state has deteriorated and the surrounding state of the electronic device 10 has changed during a predetermined time. If the indoor determination unit 440 determines that the reception state has deteriorated and the state of the surroundings of the electronic device 10 has changed during the predetermined time, the indoor determination unit 440 executes step s34 and determines “indoor”. On the other hand, if the reception state deteriorates and the surrounding state of the electronic device 10 does not change during the predetermined time, step s36 is executed to determine that “outdoor”.

The indoor determination unit 440 may determine whether the strength of the magnetic field around the electronic device 10 has increased by a predetermined value or more and decreased by a predetermined value or more based on the detection result of the geomagnetic sensor 230. it can.

  In addition, in step s41, when the state of the air around the electronic device 10 changes, the indoor determination unit 440 may determine that the state around the electronic device 10 has changed. In this case, the indoor determination unit 440 determines whether or not the state of the air around the electronic device 10 has changed, for example, based on the detection result of the sensor 260 illustrated in FIG. 11 described above. When the sensor 260 is, for example, a gas sensor, the indoor determination unit 440 changes the state of the air around the electronic device 10 when at least one of the type and concentration of the gas detected by the sensor 260 significantly changes. Is determined. When the sensor 260 is, for example, an odor sensor, the indoor determination unit 440 determines whether the state of the air around the electronic device 10 changes when at least one of the type and concentration of the odor detected by the sensor 260 significantly changes.

By specifying, the electronic device 10 can more correctly specify that the user 9 has left the outdoors.

<Fourth Example of Indoor Determination: Indoor Determination Based on User Behavior Pattern>
In this example, the indoor determination unit 440 determines whether the user 9 is indoors based on the behavior pattern information 700 indicating the behavior pattern of the user 9. In this example, as shown in FIG. 17, the electronic device 10 can communicate with the server device 800 that stores the behavior pattern information 700 using the wireless communication unit 110. When performing the indoor determination, the electronic device 10 acquires the behavior pattern information 700 from the server device 800.

  FIG. 18 is a diagram illustrating an example of the behavior pattern information 700. As shown in FIG. 18, the behavior pattern information 700 includes, for each of a plurality of time zones of the day, the probability that the user 9 is at home in the relevant time zone on weekdays (home ratio) and the The probability that the user 9 is at home in the time zone (home ratio) is associated with the time. For example, in the time zone after 12:00 am and before 3:00 am, the home rate in the time zone on weekdays is 90%, and the home rate in the time zone on holidays is 90%. . Further, in the time period after 9:00 am and before 12:00 pm, the home rate in the time zone on weekdays is 10%, and the home rate in the holiday time zone is 40%. .

  The indoor determination unit 440 acquires the behavior pattern information 700 from the server device 800 in the indoor determination. Then, the indoor determination unit 440 acquires the home ratio of the current day of the week in the time zone including the current time from the behavior pattern information 700. For example, when the current day of the week is a weekday and the current time is 10:00 am, the indoor determination unit 440 calculates the home rate on weekdays from 9:00 am to 12:00 pm from the behavior pattern information 700. Acquire a certain 10%. The indoor determination unit 440 can obtain the current time and the current day of the week from a real-time clock or the like provided in the electronic device 10. Hereinafter, the home ratio acquired from the behavior pattern information 700 in the indoor determination may be referred to as an “acquired home ratio”.

  The indoor determination unit 440 determines whether the user 9 is indoors based on the acquired home ratio. For example, when the acquired home ratio is 80% or more, the indoor determination unit 440 determines that the user 9 exists indoors. On the other hand, for example, when the acquired home ratio is less than 80%, the indoor determination unit 440 determines that the user 9 does not exist indoors.

  In the example of FIG. 18, if the current time is 2:00 pm and the current day is a holiday, the acquired home ratio is 30%, and the indoor determination unit 440 determines “outdoor”. In the example of FIG. 18, when the current time is 5:00 am and the current day of the week is a weekday, the acquired home ratio is 80%, and the indoor determination unit 440 determines “indoor”.

  The behavior pattern information 700 may be generated by the server device 800 or may be generated by the electronic device 10. The behavior pattern information 700 can be generated based on, for example, position information of the electronic device 10.

  When the server device 800 generates the behavior pattern information 700, for example, the electronic device 10 periodically transmits the position information acquired by the receiving unit 140 to the server device 800. In addition, the electronic device 10 transmits home information indicating the home address of the user 9 to the server device 800. The server device 800 generates the behavior pattern information 700 based on the position information and the home information received from the electronic device 10. For example, the server device 800 specifies that the user 9 is at home from 12:00 am to 3:00 am during eight days out of ten days on weekdays based on the location information and the home information of the electronic device 10. In this case, the home rate on weekdays in the time zone is set to 80%. The method of generating the behavior pattern information 700 is not limited to this.

  In addition, when the user 9 is at home, the user 9 performs a predetermined operation on the electronic device 10, so that at-home information indicating that the user 9 is at home may be input to the electronic device 10. In this case, the electronic device 10 may generate the behavior pattern information 700 based on the input home information. The electronic device 10 may notify the server device 800 of the input home information. In this case, the server device 800 may generate the behavior pattern information 700 based on the at-home information received from the electronic device 10.

  As described above, the indoor determination unit 440 determines whether the user 9 is indoors based on the behavior pattern information 700 indicating the behavior pattern of the user 9, so that the electronic device 10 determines that the user 9 is indoors. It can be more correctly determined whether or not there is.

  The behavior pattern information 700 is not limited to the example of FIG. The behavior pattern information 700 may include, for example, the probability that the user 9 is in the workplace (workplace rate) in each time zone on weekdays and holidays. In this case, the indoor determination unit 440 acquires the work day rate of the current day of the week in the time zone including the current time from the behavior pattern information 700, and determines whether the user 9 is indoors based on the acquired work place rate. May be determined. For example, the indoor determination unit 440 determines “indoor” when the acquired workplace rate is 80% or more, and determines “outdoor” when the obtained workplace rate is less than 80%.

  Further, the indoor determination unit 440 may determine whether the user 9 is indoors based on the behavior pattern information 700 and other information. For example, the indoor determination unit 440 determines the connection state of communication between the Wi-Fi access point (hereinafter, referred to as “home access point”) provided at the home of the user 9 and the wireless communication unit 110, and the behavior pattern information 700. Based on the above, it may be determined whether or not the user 9 exists indoors. Hereinafter, simply the connection state refers to the connection state of communication between the home access point and the wireless communication unit 110.

  When the indoor determination unit 440 determines whether or not the user 9 exists indoors based on the behavior pattern information 700 and the connection state, for example, the user determines the user Weighting (importance) for determining whether or not 9 exists indoors is given, and the weighting is also given to the type of connection state. It can be said that this weighting indicates the certainty that the user 9 exists indoors, which is derived from the information corresponding to the weighting.

  For example, when the home ratio is A%, the weight is A. Therefore, when the home ratio is 90%, the weight is 90. When the home access point and the wireless communication unit 110 are stably connected for communication, the weight is set to 90. If the communication connection between the home access point and the wireless communication unit 110 is unstable, the weight is set to 50. When the home access point and the wireless communication unit 110 are not connected for communication, that is, when they are not connected, the weight is set to 10.

  In the indoor determination, the indoor determination unit 440 acquires the home ratio according to the current time and the current day of the week from the behavior pattern information 700 and specifies the connection state. Then, the indoor determination unit 440 obtains an added value of the weight according to the acquired home ratio and the weight according to the specified connection state. The indoor determination unit 440 determines “indoor” when the obtained added value of the weights is equal to or greater than the ninth threshold, and determines “outdoor” when the added value is smaller than the ninth threshold. The ninth threshold value is set to, for example, 120.

  For example, if the acquired home ratio is 90% (weighting 90) and it is specified that the home access point and the wireless communication unit 110 are stably connected for communication (weighting 90), the added value of the weighting is 180. Become. In this case, it is determined to be “indoor”. When the acquired home ratio is 30% (weighting 30) and it is specified that the home access point and the wireless communication unit 110 are not connected for communication (weighting 10), the added value of the weighting is 40. In this case, it is determined to be “outdoor”. When the acquired home ratio is 80% (weighting 80) and it is specified that the communication connection between the home access point and the wireless communication unit 110 is unstable (weighting 50), the weighting addition value is 130. . In this case, it is determined to be “indoor”.

  In addition, the indoor determination unit 440 may determine whether the user 9 is indoors based on the result of the stop movement identification performed by the stop movement identification unit 410 and the action pattern information 700. In this case, for example, similarly to the above, the value of the home ratio is weighted. The “stop of user 9” specified by the stop movement specification is given a weight of 90, and the “walk” and “run” of the moving means of the user 9 specified by the stop movement specification are 50 and 10 respectively. Is given. The “bicycle” and “vehicle” of the moving means of the user 9 specified by the stop movement specification need not be used in indoor determination.

  In the indoor determination, the indoor determination unit 440 obtains the home ratio according to the current time and the current day of the week from the behavior pattern information 700 and confirms the result of the stop movement identification. Then, the indoor determination unit 440 obtains an added value of the weight according to the acquired home ratio and the weight according to the content specified in the stop movement specification. The indoor determination unit 440 determines “indoor” when the calculated weighted value is equal to or larger than the tenth threshold, and determines “outdoor” when the calculated weighted value is smaller than the tenth threshold. The tenth threshold value is set to, for example, 120.

  For example, when the acquired home ratio is 90% (weighting 90) and “walk” is specified in the stop movement specification (weighting 50), the added value of the weighting is 140. In this case, it is determined to be “indoor”. When the acquired home ratio is 70% (weighting 70) and “running” is specified in the stop movement specification (weighting 10), the weighted addition value is 80. In this case, it is determined to be “outdoor”. If the acquired home ratio is 80% (weighting 80) and “stop of user 9” is specified in the stop movement specification (weighting 90), the sum of the weights is 170. In this case, it is determined to be “indoor”.

  Also, the indoor determination unit 440 determines whether or not the user 9 exists indoors based on the result of the stop movement identification by the stop movement identification unit 410, the connection state, and the behavior pattern information 700. Good. In this case, for example, similarly to the above, the type of the connection state is weighted, the value of the home ratio is weighted, and the content specified by the stop movement specification is weighted. In the indoor determination, the indoor determination unit 440 acquires the home rate according to the current time and the current day of the week from the behavior pattern information 700, confirms the result of the stop movement specification, and specifies the connection state. Then, the indoor determination unit 440 obtains an added value of the weight according to the acquired home ratio, the weight according to the content specified in the stop movement specification, and the weight according to the specified connection state. The indoor determination unit 440 determines “indoor” when the obtained weighted addition value is equal to or larger than the eleventh threshold, and determines “outdoor” when the added value is smaller than the eleventh threshold. The eleventh threshold value is set to, for example, 180.

  For example, the acquired home ratio is 40% (weighting 40), "walk" is specified in the stop movement specification (weighting 50), and the communication connection between the home access point and the wireless communication unit 110 is specified to be unstable. In this case (weight 50), the sum of the weights becomes 140. In this case, it is determined to be “outdoor”. In addition, the acquired home ratio is 80% (weighted 80), "stop of user 9" is specified in the stop movement specification (weighted 90), and the home access point and the wireless communication unit 110 are stably connected for communication. If it is determined that the data is present (weight 90), the sum of the weights is 260. In this case, it is determined to be “indoor”.

  As described above, the indoor determination unit 440 determines whether or not the user 9 is indoors based on the behavior pattern information 700 and at least one of the result of the specified stop movement and the connection state, and thereby the electronic device 10 Can more correctly determine whether the user 9 exists indoors.

  As described above, the four types of indoor determination according to the first to fourth examples have been described. In step s3 described above, the indoor determination unit 440 performs two or more indoor determinations among the four indoor determinations as a provisional indoor determination, and based on the result of the provisional indoor determination, the user 9 May be finally determined. For example, the indoor determination unit 440 finally determines that the user 9 is present indoor when at least one type of provisional indoor determination of the executed two or more types of temporary indoor determinations determines “indoor”. . Then, in each of the two or more types of provisional indoor determinations that have been performed, the indoor determination unit 440 finally determines that the user 9 does not exist indoors when the outdoor determination is performed.
