For example, the deterioration of the detection accuracy of the GPS receiver 18 includes a case where the strength, sensitivity, etc. of signals received from a plurality of positioning satellites used in GPS deteriorate. For example, when the user carrying the electronic device 1 moves indoors from the outdoors, the GPS receiver 18 becomes difficult to receive a signal from a positioning satellite or cannot receive a signal from a positioning satellite. That is, when the detection accuracy of the GPS receiver 18 deteriorates, the electronic device 1 can estimate that the user has entered the room, underground, or the like. The control program 9 </ b> A can provide a function of controlling communication with the other device by the communication unit 6 based on the detection accuracy of the GPS receiver 18.

The control program 9A estimates that the user is in a safe place when the position where the detection accuracy of the GPS receiver 18 has deteriorated matches the position of the user's home, company, etc. registered in advance. Can provide functionality. For example, a user who is outdoors may jump out on a road or the like. For this reason, the driver who drives the car needs to pay attention to a person who is not in a safe place as a target of danger, but does not need to pay attention to a person who is in a safe place as a target of danger.

For example, the information on the user relating to traffic includes information for notifying the driver of the vehicle of the presence of the user.

  The acceleration data 9B includes a plurality of pieces of acceleration information transmitted to the controller 10 as a detection result of the acceleration sensor 15. The acceleration data 9B can indicate a plurality of acceleration information in time series. The acceleration information includes, for example, time and an acceleration value. The time indicates the time when the acceleration sensor 15 detects the direction and magnitude of acceleration. The acceleration value indicates the direction and magnitude of the acceleration detected by the acceleration sensor 15.

  For example, the detection result of the acceleration sensor 15 is transmitted to the controller 10. The detection result includes an acceleration value in the X-axis direction, an acceleration value in the Y-axis direction, an acceleration value in the Z-axis direction, and a vector value obtained by combining the acceleration values. The controller 10 logs the detection result of the acceleration sensor 15 in the acceleration data 9B of the storage 9. The controller 10 may calculate a combined vector value by calculating an acceleration value in the X-axis direction, an acceleration value in the Y-axis direction, and an acceleration value in the Z-axis direction.

  The state data 9C includes information indicating a plurality of states of the own device. The plurality of states include, for example, a stopped state, a stationary state, a walking state, a traveling state, a moving state on a vehicle, and a moving state on a bicycle. The controller 10 updates the state data 9C in response to detection of a change in the state of the own device.

  The discrimination data 9D includes an acceleration pattern corresponding to each of a plurality of states of the own device. The acceleration pattern includes an acceleration pattern obtained by measuring and extracting in advance what kind of acceleration pattern is characteristically detected by the acceleration sensor 15 for each of a plurality of states of the own device. The acceleration pattern is stored so as to correspond to the logged data of the combined vector value described above. The determination data 9D includes, for example, acceleration patterns corresponding to states such as a stopped state, a stationary state, a walking state, a running state, a moving state on a vehicle, and a moving state on a bicycle.

  For example, the controller 10 can compare the combined vector pattern of the acceleration data 9 </ b> B with the acceleration pattern of the determination data 9 </ b> D and determine the state associated with the matched acceleration pattern as the state of the electronic device 1. Note that the pattern matching includes a case where the patterns match completely or a case where they match at a predetermined rate.

  The position data 9E can store position information in time series. The position information includes, for example, a value indicating the position and a detection time. The position indicates, for example, the latitude and longitude detected by the GPS receiver 18. The time indicates the time when the position is detected by the GPS receiver 18, for example. The position data 9E may include information indicating the intensity, sensitivity, etc. of the signal received by the GPS receiver 18, for example. For example, the position data 9E may include information indicating that the detection accuracy of the GPS receiver 18 has deteriorated. The position data 9E is updated every time the GPS receiver 18 detects the position.

  In the temperature data 9F, temperature information can be stored in time series. The temperature information includes items such as time, temperature value, and temperature change amount, for example. The time indicates the time when the temperature is detected by the temperature sensor 19. The temperature value indicates the temperature value detected by the temperature sensor 19. The amount of change in temperature indicates the amount of change in temperature detected by the temperature sensor 19 per unit time. The temperature data 9F is updated every time the temperature sensor 19 detects the temperature.

  The setting data 9Z includes various data used for processing executed based on functions provided by the control program 9A and the like. The setting data 9Z includes information indicating whether or not the position detection function by the GPS receiver 18 is valid. For example, when the position detection function is effective, the electronic device 1 can detect the position of the electronic device 1 by the GPS receiver 18. For example, when the position detection function is invalid, the electronic device 1 does not detect the position of the electronic device 1 by the GPS receiver 18. For example, when the position detection function is invalid, the electronic device 1 does not operate the GPS receiver 18.

  For example, when a user is at home, the user tends to move within a certain action range. In this case, the user's continuous walking is limited to a certain number of steps. The setting data 9Z can set a certain number of steps corresponding to the user as the first threshold value for estimating that the user has moved to the outdoors.

  For example, when there is a difference in temperature between indoors and outdoors, the temperature sensor 19 may be able to detect temperature changes between indoors and outdoors. The electronic device 1 can estimate that the user has moved from indoor to outdoor by detecting a predetermined temperature change. The setting data 9Z can set a second threshold value for estimating the movement of the user from indoors to the outdoors and a predetermined change in temperature.

  For example, by executing the control program 9A, the controller 10 can execute various controls such as changing information displayed on the display 2A according to the gesture determined via the touch screen 2B.

  The controller 10 cooperates with the acceleration sensor 15, the geomagnetic sensor 16, the angular velocity sensor 17, the GPS receiver 18, and the temperature sensor 19 by executing the control program 9A. Based on the detection result of the acceleration sensor 15, the controller 10 executes processing for determining the movement state of the own device.

  The speaker 11 can output the sound signal transmitted from the controller 10 as sound. The speaker 11 may output a ring tone and music, for example. One of the receiver 7 and the speaker 11 may also function as the other.

  The camera 12 and the camera 13 can convert the captured image into an electrical signal. The camera 12 may be an in-camera that captures an object facing the display 2A. The camera 13 may be an out camera that captures an object facing the opposite surface of the display 2A. The camera 12 and the camera 13 may be mounted on the electronic apparatus 1 in a functionally and physically integrated state as a camera unit that can be used by switching between the in-camera and the out-camera.

  The geomagnetic sensor 16 can detect the orientation (azimuth) of the electronic device 1 by measuring the geomagnetism, for example. The geomagnetic sensor 16 can send the detected geomagnetic value to the controller 10. The geomagnetic sensor 16 may be either a 2-axis type or a 3-axis type. The geomagnetic sensor 16 may detect the direction and magnitude of the magnetic field.

  For example, the angular velocity sensor 17 can measure the magnitude and direction of the angular velocity of the electronic device 1. The angular velocity sensor 17 can send the detected angular velocity value to the controller 10. The controller 10 can detect the change in the orientation of the electronic device 1 based on the angular velocity pattern including the magnitude and direction of the angular velocity detected by the angular velocity sensor 17 or the time-series change in the direction and magnitude of the angular velocity.

  The GPS receiver 18 can detect the current position of the electronic device 1. The GPS receiver 18 can receive a radio signal in a predetermined frequency band from a GPS satellite, demodulate the received radio signal, and send the processed signal to the controller 10.

  FIG. 2 is a flowchart illustrating a processing procedure of an example of control by the electronic device 1. The processing procedure shown in FIG. 2 is realized by the controller 10 executing the control program 9A. The processing procedure shown in FIG. 2 is repeatedly executed by the controller 10 when information indicating that the position detection function by the GPS receiver 18 is valid is set in the setting data 9Z. The processing procedure shown in FIG. 2 is not executed by the controller 10 when information indicating that the position detection function by the GPS receiver 18 is invalid is set in the setting data 9Z.

  As illustrated in FIG. 2, the controller 10 of the electronic device 1 acquires information on sensitivity from the GPS receiver 18 in step S101. For example, the information regarding sensitivity includes information indicating positioning sensitivity, tracking sensitivity, and the like regarding a signal received from a positioning satellite.

  As Step S102, the controller 10 determines whether or not the detection accuracy of the GPS receiver 18 has deteriorated. For example, the controller 10 determines that the detection accuracy of the GPS receiver 18 has deteriorated when the sensitivity of the GPS receiver 18 has deteriorated below a predetermined value. For example, when the position measurement by the GPS receiver 18 is impossible, the controller 10 determines that the detection accuracy of the GPS receiver 18 has deteriorated. When it is determined that the detection accuracy of the GPS receiver 18 has not deteriorated (No in step S102), the controller 10 ends the processing procedure illustrated in FIG. If the controller 10 determines that the detection accuracy of the GPS receiver 18 has deteriorated (Yes in step S102), the controller 10 proceeds to step S103.

  The controller 10 suppresses communication with the other apparatus by the communication unit 6 as step S103. Other machines include, for example, a communication device mounted on a vehicle, a roadside machine, and the like. For example, when the detection accuracy of the GPS receiver 18 is deteriorated, the user is likely to be in a safe place such as indoors or underground. For example, when suppressing short-range wireless communication with another device, the controller 10 does not transmit various information to the other device by the communication unit 6, but receives signals from the other device by the communication unit 6. Can do. When the controller 10 starts to suppress communication with another device, the process proceeds to step S104.

  When the controller 10 acquires information on sensitivity from the GPS receiver 18 as step S104, the process proceeds to step S105.

  As Step S105, the controller 10 determines whether or not the detection accuracy of the GPS receiver 18 has been recovered. For example, the controller 10 determines that the detection accuracy of the GPS receiver 18 has recovered if the sensitivity of the GPS receiver 18 has not deteriorated below a predetermined value. For example, the controller 10 determines that the detection accuracy of the GPS receiver 18 has been restored when the GPS receiver 18 can measure the position. If the controller 10 determines that the detection accuracy of the GPS receiver 18 has not recovered (No in step S105), the controller 10 returns the process to step S104 already described. If the controller 10 determines that the detection accuracy of the GPS receiver 18 has been recovered (Yes in step S105), the controller 10 proceeds to step S106.

  The controller 10 cancels | suppresses suppression of communication with the other apparatus by the communication unit 6 as step S106. For example, when the detection accuracy of the GPS receiver 18 that has deteriorated is recovered, the user is likely to have moved from a safe place to the outdoors. For example, the controller 10 can enable the communication unit 6 to transmit / receive information to / from another device by canceling the suppression of communication. When the controller 10 cancels the suppression of communication with the other device, the controller 10 ends the processing procedure shown in FIG.

  When the detection accuracy of the GPS receiver 18 deteriorates, the electronic device 1 can be estimated that the user is in a safe place where the possibility of encountering a traffic accident such as indoors or underground is low. When the detection accuracy of the GPS receiver 18 deteriorates, the electronic device 1 can suppress communication with other devices by the communication unit 6. As a result, the electronic device 1 can provide a highly convenient communication method with another device according to the detection accuracy state of the GPS receiver 18. Since the electronic device 1 can suppress the power consumption of the communication unit 6 while the detection accuracy of the GPS receiver 18 is deteriorated, the battery of the electronic device 1 can be prolonged. For example, when the electronic device 1 notifies the presence of the user to another device located in the vicinity of the own device, the notification can be suppressed if the detection accuracy of the GPS receiver 18 deteriorates. As a result, when the function for detecting the position of the GPS receiver 18 is effective, the electronic device 1 can reduce communication traffic because communication with unnecessary other devices is reduced.

  When the detection accuracy of the GPS receiver 18 is restored, the electronic device 1 can estimate that the user has left a safe place. When the detection accuracy of the GPS receiver 18 is restored, the electronic device 1 can automatically cancel suppression of communication with the other device by the communication unit 6. As a result, the electronic device 1 can control suppression of communication with other devices by the communication unit 6 depending on whether or not the user is in a safe place.

  Hereinafter, an electronic apparatus 1 according to another example of the embodiment will be described. The electronic device 1 according to another example of the embodiment has the same configuration as the electronic device 1 illustrated in FIG. 1 except that the function of the control program 9A is different.

  FIG. 3 is a flowchart illustrating a processing procedure of another example of control by the electronic device 1. The processing procedure shown in FIG. 3 is realized by the controller 10 executing the control program 9A. The processing procedure shown in FIG. 3 is repeatedly executed by the controller 10 when information indicating that the position detection function by the GPS receiver 18 is valid is set in the setting data 9Z. The processing procedure illustrated in FIG. 3 is not executed by the controller 10 when information indicating that the position detection function by the GPS receiver 18 is invalid is set in the setting data 9Z.

  In the example shown in FIG. 3, the processing from step S101 to step S103 and step S106 is the same as the processing from step S101 to step S103 and step S106 shown in FIG. Is omitted.

  As illustrated in FIG. 3, when the controller 10 of the electronic device 1 suppresses communication with another device by the communication unit 6 in step S103, the process proceeds to step S111. In step S111, the controller 10 determines the state of the own device based on the acceleration data 9B. For example, the controller 10 compares the acceleration pattern of the acceleration data 9B with the acceleration pattern for each state of the determination data 9D, and determines the state corresponding to the matching acceleration pattern of the determination data 9D as the state of the own device. The controller 10 stores the determined state in the state data 9C.

  As Step S112, the controller 10 determines whether or not the state of its own device has transitioned to the moving state on the vehicle. For example, the controller 10 determines that the vehicle is moving in step S111, and determines that the vehicle has changed to the vehicle moving state when the state before the determination is another state such as a stationary state or a stopped state. To do. If the controller 10 determines that the vehicle has not changed to the moving state (No in step S112), the controller 10 returns the process to step S111 already described. If the controller 10 determines that the vehicle has moved to the moving state (Yes in step S112), the controller 10 proceeds to step S106 described above. When the process of step S106 is completed, the controller 10 ends the processing procedure shown in FIG.

  In the example illustrated in FIG. 3, the electronic apparatus 1 has been described with respect to the case where the condition for releasing the suppression of communication is the transition to the moving state on the vehicle, but is not limited thereto. For example, the electronic device 1 may add the recovery of the detection accuracy of the GPS receiver 18 to the condition for canceling the suppression of communication, as in the example illustrated in FIG.

  After the detection accuracy of the GPS receiver 18 deteriorates, the electronic device 1 can cancel the suppression of communication with the other device by the communication unit 6 when the state of the own device transitions to the moving state of the vehicle. The electronic device 1 can estimate that the user has moved from a safe place according to the detection accuracy state of the GPS receiver 18. For example, when the vehicle is a car, a train or the like, the user does not become a traffic weak person. In such a case, the electronic device 1 may continue to suppress communication with other devices by the communication unit 6.

  FIG. 4 is a flowchart illustrating a processing procedure of another example of control by the electronic device 1. The processing procedure shown in FIG. 4 is realized by the controller 10 executing the control program 9A. The processing procedure shown in FIG. 4 is repeatedly executed by the controller 10 when information indicating that the position detection function by the GPS receiver 18 is valid is set in the setting data 9Z. The processing procedure shown in FIG. 4 is not executed by the controller 10 when information indicating that the position detection function by the GPS receiver 18 is invalid is set in the setting data 9Z.

  In the example shown in FIG. 4, the processing from step S101 to step S106 is the same as the processing from step S101 to step S106 shown in FIG. 2, so only the different parts will be described and the description of the same parts will be omitted.

  As illustrated in FIG. 4, when the controller 10 of the electronic device 1 determines that the detection accuracy of the GPS receiver 18 has not recovered (No in step S105), the process proceeds to step S121. In step S121, the controller 10 detects the number of steps and directions the user has walked based on the detection results of the acceleration sensor 15, the angular velocity sensor 17, and the geomagnetic sensor 16. For example, the controller 10 detects the number of steps of the user carrying the device based on the detected acceleration by executing a step count counting program. For example, the controller 10 detects the direction in which the user is walking based on the detected angular velocity, geomagnetism, and the like by executing a step counting program. The controller 10 stores the detected number of steps and direction in the storage 9, and advances the process to step S122.

  As Step S122, the controller 10 estimates whether or not the user has returned to the position where the detection accuracy of the GPS receiver 18 has been deteriorated. For example, the controller 10 determines whether the user has returned to the position based on the number of steps and direction of the user detected after determining that the detection accuracy of the GPS receiver 18 has deteriorated and the first threshold value of the setting data 9Z. Is estimated. For example, if a user returns to a position that entered a safe place, the user may leave the safe place. In this case, the detection accuracy of the GPS receiver 18 may be recovered. The controller 10 can estimate the recovery of the detection accuracy of the GPS receiver 18 by estimating that the user has returned to the position where the user entered the safe place. When the controller 10 stores the estimation result in the storage 9, the process proceeds to step S123.

  As Step S123, the controller 10 determines whether or not it is estimated that the user has returned based on the estimation result of Step S122. If it is determined that the user has not returned (No in step S123), the controller 10 returns the process to step S104 already described. If the controller 10 determines that the user has returned (Yes in step S123), the controller 10 proceeds to step S106 already described. When the process of step S106 is completed, the controller 10 ends the processing procedure shown in FIG.

  In the example illustrated in FIG. 4, the electronic device 1 has been described as using the recovery of the detection accuracy of the GPS receiver 18 as a condition for canceling the suppression of communication, but is not limited thereto. For example, the electronic device 1 may not use the recovery of the detection accuracy of the GPS receiver 18 as a condition for releasing the suppression of communication.

  If the detection accuracy of the GPS receiver 18 has not recovered after the detection accuracy of the GPS receiver 18 has deteriorated, the electronic device 1 communicates when the user returns to the position where it has been determined that the detection accuracy of the GPS receiver 18 has deteriorated. The suppression of communication with other devices by the unit 6 can be released. As a result, since the electronic device 1 can suppress communication with the other device by the communication unit 6 from when the user enters the safe place until returning to the place, the electronic device 1 is highly convenient. A communication method with a machine can be provided.

  FIG. 5 is a flowchart illustrating a processing procedure of another example of control by the electronic device 1. The processing procedure shown in FIG. 5 is realized by the controller 10 executing the control program 9A. The processing procedure shown in FIG. 5 is repeatedly executed by the controller 10 when information indicating that the position detection function by the GPS receiver 18 is valid is set in the setting data 9Z. The processing procedure shown in FIG. 5 is not executed by the controller 10 when information indicating that the position detection function by the GPS receiver 18 is invalid is set in the setting data 9Z.

  In the example shown in FIG. 5, the processing from step S101 to step S106 is the same as the processing from step S101 to step S106 shown in FIG. 2, so only the different parts will be described and the description of the same parts will be omitted.

  As illustrated in FIG. 5, when the controller 10 of the electronic device 1 determines that the detection accuracy of the GPS receiver 18 has not recovered (No in step S105), the process proceeds to step S131. In step S131, the controller 10 detects a change in temperature after determining that the detection accuracy of the GPS receiver 18 has deteriorated based on the detection result of the temperature sensor 19. For example, the controller 10 detects a change in temperature in a predetermined period from the temperature data 9F. The predetermined period includes, for example, a period from a current time to a time that goes back a certain time.

  As Step S132, the controller 10 determines whether or not a predetermined temperature change has been detected. For example, when the detected temperature change is larger than the second threshold value of the setting data 9Z, the controller 10 determines that a predetermined temperature change has been detected. When it is determined that the predetermined temperature change has not been detected (No in step S132), the controller 10 returns the process to step S104 already described. If the controller 10 determines that a predetermined temperature change has been detected (Yes in step S132), the controller 10 proceeds to step S106 already described. When the process of step S106 ends, the controller 10 ends the processing procedure shown in FIG.

  In the example illustrated in FIG. 5, the electronic apparatus 1 has been described with respect to the case where the recovery of the detection accuracy of the GPS receiver 18 is used as a condition for canceling the suppression of communication. However, the present invention is not limited to this. For example, the electronic device 1 may not use the recovery of the detection accuracy of the GPS receiver 18 as a condition for releasing the suppression of communication.

  If the detection accuracy of the GPS receiver 18 has not recovered after the detection accuracy of the GPS receiver 18 has deteriorated, the electronic device 1 cancels suppression of communication with the other device by the communication unit 6 when detecting a predetermined temperature change. can do. As a result, since the electronic device 1 can suppress communication with the other device by the communication unit 6 while the user stays in a safe place, a highly convenient communication method with the other device can be provided. .

  FIG. 6 is a flowchart illustrating a processing procedure of another example of control by the electronic device 1. The processing procedure shown in FIG. 6 is realized by the controller 10 executing the control program 9A. The processing procedure shown in FIG. 6 is repeatedly executed by the controller 10 when information indicating that the position detection function by the GPS receiver 18 is valid is set in the setting data 9Z. The processing procedure shown in FIG. 6 is not executed by the controller 10 when information indicating that the position detection function by the GPS receiver 18 is invalid is set in the setting data 9Z.

  In the example shown in FIG. 6, the processing from step S101 to step S106 is the same as the processing from step S101 to step S106 shown in FIG. 2, so only the different parts will be described and the description of the same parts will be omitted.

  As illustrated in FIG. 6, when the controller 10 of the electronic device 1 determines that the detection accuracy of the GPS receiver 18 has not deteriorated (No in step S102), the process proceeds to step S141. The controller 10 discriminate | determines the state of an own machine based on the acceleration data 9B as step S141, and advances a process to step S142.

  As Step S142, the controller 10 determines whether or not the state of its own device is a moving state on the vehicle based on the determination result of Step S141. If the controller 10 determines that the vehicle is not in a moving state (No in step S142), the controller 10 ends the processing procedure shown in FIG. If the controller 10 determines that the vehicle is moving (Yes in step S142), the process proceeds to step S143.

  Similarly to step S103, the controller 10 suppresses communication with the other apparatus by the communication unit 6 as step S143, and advances the process to step S144. The controller 10 discriminate | determines the state of an own machine based on the acceleration data 9B as step S144, and advances a process to step S145.

  As Step S145, the controller 10 determines whether or not the state of its own device has changed from the moving state of the vehicle to another state based on the determination result of Step S144. If the controller 10 determines that the vehicle state has not changed to another state (No in step S145), the controller 10 returns the process to step S144 already described. When it is determined that the controller 10 has transitioned from the moving state on the vehicle to another state (Yes in step S145), the controller 10 proceeds to step S146.

  Similarly to step S106, the controller 10 cancels the suppression of communication with other devices by the communication unit 6 in step S146. When the controller 10 cancels the suppression of communication, the controller 10 ends the processing procedure shown in FIG.

  When the detection accuracy of the GPS receiver 18 is not deteriorated, the electronic device 1 can suppress communication with other devices by the communication unit 6 when the electronic device 1 is in a moving state on a vehicle such as a vehicle or a train. As a result, the electronic device 1 can suppress communication with the other device by the communication unit 6 while the user is moving on a vehicle such as a vehicle or a train. Can provide a method.

  In the above embodiment, the electronic device 1 has been described with respect to the case where each of the processing procedures illustrated in FIGS. 2 to 6 is executed by the controller 10, but the present invention is not limited to this. For example, the processing procedure shown in FIGS. 2 to 6 may be a processing procedure that combines them.

  FIG. 7 is a system diagram illustrating an example of a system configuration of the notification system 100. An example of the notification system 100 including the electronic device 1 will be described with reference to FIG.

  As shown in FIG. 7, the notification system 100 includes the electronic device 1, a roadside device 200, and a vehicle 300. The roadside machine 200 is provided in a predetermined area or in the vicinity of the predetermined area. The predetermined area includes, for example, areas such as roads, intersections, and parking lots. The predetermined area may be, for example, an area including a place where a traffic accident may occur. The roadside device 200 can transmit radio waves to a large number of unspecified electronic devices in and near a predetermined area. The vehicle 300 includes, for example, an automobile, a truck, a bus, a taxi, an emergency vehicle, and the like. The vehicle 300 includes an in-vehicle device 310. The in-vehicle device 310 is mounted on the vehicle 300 so that, for example, radio waves from the roadside device 200 can be received. The vehicle-mounted device 310 includes a vehicle-mounted device mounted on the vehicle 300 such as a navigation device, an ETC (Electronic Toll Collection System) vehicle-mounted device, a combination meter, and a car audio. The in-vehicle device 310 may be, for example, an electronic device that is brought into the vehicle 300 by the driver. Electronic devices brought into the vehicle 300 include, for example, a smartphone, a mobile phone, a wearable device, a portable game machine, and the like.

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

  For example, a user carrying the electronic device 1 is walking outdoors. In this case, the user is a traffic weak person who may have a traffic accident with the vehicle 300 such as an automobile or a motorcycle. The electronic device 1 has a function of notifying the driver of the vehicle 300 or the like of the presence of the user in order to protect a vulnerable person. When the detection accuracy of the GPS receiver 18 is not deteriorated, the electronic device 1 can estimate that the user is in a dangerous place outdoors. When the electronic device 1 estimates that the user is not in a safe place, the electronic device 1 performs a notification process for an external device.

  As illustrated in FIG. 7, when the roadside device 200 and the in-vehicle device 310 that can communicate with each other exist in the vicinity of the electronic device 1, the electronic device 1 notifies the roadside device 200 and the in-vehicle device 310 of the presence of the user. A radio wave including notification information D for transmission is transmitted by short-range radio. As a result, the electronic device 1 can notify the presence of the user to the roadside device 200, the in-vehicle device 310, and the like, so that the safety of the user can be improved. On the other hand, when the in-vehicle device 310 receives the notification information D from the electronic device 1 carried by a user who is not in a safe place, for example, the vehicle-mounted device 310 notifies the driver that there is a pedestrian at risk of jumping out. be able to. As a result, the driver can improve the possibility of avoiding a traffic accident with a traffic weak person such as a pedestrian or a bicycle. Further, when the roadside device 200 receives the notification information D from the electronic device 1 carried by a user who is not in a safe place, for example, the roadside device 200 notifies the vehicle 300 approaching the roadside device 200, the vehicle-mounted device 310, and the like. Information D can be transferred. As a result, the roadside machine 200 can contribute to avoiding a traffic accident between the vehicle 300 and a vulnerable person.

  For example, a user who carries the electronic device 1 enters a safe place in a building 500 such as a home or office from outside. Since the GPS receiver 18 of the electronic device 1 is located in the building 500 where it is difficult to receive a signal from a positioning satellite, the detection accuracy is deteriorated. When the electronic device 1 detects the deterioration of the detection accuracy of the GPS receiver 18, the electronic device 1 suppresses communication with the other device by the communication unit 6. The electronic device 1 does not execute the notification process for the other device when the communication unit 6 suppresses communication with the other device. As a result, since the electronic device 1 does not operate the communication unit 6, an increase in power consumption can be suppressed. On the other hand, since the vehicle-mounted device 310 does not receive a notification from the electronic device 1 carried by a user in a safe place, only the necessary information can be provided to the driver.

  In the above embodiment, the electronic device 1 has been described with respect to the case where the communication unit 6 controls communication with another device based on the detection accuracy of the GPS receiver 18, but the present invention is not limited to this. For example, the electronic device 1 may estimate whether the user is in a safe place based on the detection accuracy of the GPS receiver 18 and the position where the detection accuracy has deteriorated. In this case, the electronic apparatus 1 detects that the detection accuracy of the GPS receiver 18 has deteriorated, and if the position where the detection accuracy has deteriorated is a pre-registered position, it is estimated that the user is in a safe place. That's fine.

  In said embodiment, although the electronic device 1 demonstrated the case where the communication process with the other apparatus by the communication unit 6 is suppressed, the case where the alerting | reporting process with respect to another apparatus is not performed was demonstrated, It is not limited to this. For example, if the electronic device 1 periodically and repeatedly attempts to communicate with another device by the communication unit 6, in the notification process for the other device, when communication with the other device by the communication unit 6 is suppressed, The number of trials per unit time may be reduced. For example, when the electronic device 1 suppresses communication with another device by the communication unit 6, the amount of data to be transmitted by the notification process may be reduced.

  In the above embodiment, the GPS receiver is exemplified as the position detection unit that detects the position information of the own apparatus based on the signal output from the satellite. However, based on the signal output from the positioning satellite other than the GPS satellite, What detects position information may be used. The positioning satellites other than the GPS satellites are positioning satellites such as GLONASS (Global Navigation Satellite System), IRNSS (Indian Regional Navigation System), COMPASS, and GALILEO.
