Description

[Technical Field]

[0001] There is a service in which, when a vehicle accident occurs, a device (a drive recorder or a smartphone) installed in the vehicle automatically transmits information about the accident (accident information) to an external device and automatically calls a call center, enabling a conversation with a call center operator (for example, Patent Document 1). In such a service, for example, when the acceleration measured by an acceleration sensor exceeds a predetermined value, the device installed in the vehicle determines that an impact due to a vehicle accident has occurred, and automatically transmits the accident information to an external device and calls the call center.

[0002] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-46125 Summary of the Invention [Problem to be solved by the invention]

[0003] For example, a drive recorder is attached to the windshield or rear window of a vehicle using mounting parts such as double-sided tape or suction cups. Due to factors such as vibrations during driving, the mounting condition may deteriorate, causing the drive recorder to come off from its mounting location and fall. After falling, the drive recorder may collide with an object such as the dashboard or floor, resulting in an impact on the drive recorder. Even if the drive recorder experiences an impact due to a fall, the acceleration measured by the acceleration sensor installed in the drive recorder may exceed a predetermined value. In such a case, the drive recorder may automatically transmit accident information to an external device and call a call center, even though no accident has occurred with the vehicle.

[0010] An information processing device according to one embodiment of the present invention includes a fall detection unit that detects the occurrence of a fall of a device attached to a mobile object, and a message output processing unit that, if the occurrence of the device falling is repeatedly detected, outputs information related to a message prompting the user of the mobile object to replace the attachment parts used to attach the device to the mobile object. In this manner, in this embodiment, when the attachment condition of the device attached to the mobile object deteriorates, it is possible to prompt the user of the mobile object to replace the attachment parts. Therefore, in this embodiment, it is possible to reduce the occurrence of a device attached to the mobile object falling. As a result, it is possible to reduce the detection of impacts caused by a device attached to the mobile object falling, and to reduce unnecessary notifications.

[0011] The device may have an acceleration acquisition processing unit that acquires acceleration measured by an acceleration sensor provided in the device, and the fall detection unit may detect the occurrence of a fall of the device based on the magnitude of the acceleration. In this way, it is possible to accurately detect the occurrence of a fall of a device attached to a mobile object.

[0012] The message output processor may determine that the device has repeatedly fallen when the occurrence of the device falling is detected a predetermined number of times within a predetermined period. The device may further include a usage status acquisition processor that acquires usage status of the mobile object, and the predetermined period may be determined based on usage status of the mobile object. In this way, it is possible to determine the degree of deterioration of the mounting member depending on usage status of the mobile object.

[0013] The usage status of the mobile object may be determined based on measurements by the acceleration sensor. The device may further include a mobile object position information acquisition processing unit that acquires mobile object position information including information about the position of the mobile object, and the usage status of the mobile object may be determined based on the mobile object position information. The device may further include a device activation information acquisition processing unit that acquires device activation information including information about activation of the device, and the usage status of the mobile object may be determined based on the device activation information. In this way, the usage status of the mobile object can be automatically acquired without relying on user input.

[0014] Furthermore, an information processing device according to one embodiment of the present invention includes a fall information acquisition processing unit that acquires information regarding the occurrence of a fall of a device attached to a mobile body, and a message output processing unit that, if repeated falls of the device are detected, outputs information regarding a message urging the user of the mobile body to replace the attachment parts used to attach the device to the mobile body. In this manner, in this embodiment, when the attachment condition of a device attached to a mobile body deteriorates, it is possible to prompt the user of the mobile body to replace the attachment parts. Therefore, in this embodiment, it is possible to reduce the occurrence of a device attached to a mobile body falling. As a result, it is possible to reduce the detection of impacts caused by a device attached to a mobile body falling, and to reduce unnecessary notifications.

[0015] Furthermore, an information processing method according to one embodiment of the present invention is an information processing method executed by a computer, and includes a fall detection step of detecting the occurrence of a fall of a device attached to a mobile body, and a message output processing step of outputting information related to a message prompting the user of the mobile body to replace an attachment part used to attach the device to the mobile body if the occurrence of the device falling is repeatedly detected. In this manner, in this embodiment, when the attachment condition of a device attached to a mobile body deteriorates, it is possible to prompt the user of the mobile body to replace the attachment part. Therefore, in this embodiment, it is possible to reduce the occurrence of a device attached to a mobile body falling. As a result, it is possible to reduce the detection of an impact caused by a device attached to a mobile body falling, and it is possible to reduce unnecessary notifications.

[0016] Furthermore, an information processing program according to an embodiment of the present invention causes a computer to execute the above-described information processing method, thereby making it possible to prompt a user of a mobile object to replace an attachment member using the computer.

[0017] Furthermore, a computer-readable storage medium according to an embodiment of the present invention stores the information processing program, which allows the information processing program to be distributed as a standalone program in addition to being incorporated into a device, and makes it easy to perform version upgrades, etc. [Example]

[0018] <Information processing device 100> 1 shows an information processing device 100 according to an embodiment of the present invention. The information processing device 100 includes a control unit 110, a communication unit 120, an acceleration sensor 130, a call unit 140, an image data acquisition unit 150, an output unit 160, an input unit 170, and a position information acquisition unit 180.

[0019] The control unit 110 is configured by, for example, a computer. The communication unit 120 is a communication device for transmitting and receiving information to and from other devices. The acceleration sensor 130 is a device for measuring the magnitude and direction of acceleration, such as a three-axis acceleration sensor. The call unit 140 is a device for making calls via a telephone network. The image data acquisition unit 150 is a device for acquiring image data from a camera or the like. The output unit 160 is an output device for outputting information, such as a display or speaker. The input unit 170 is an input device for receiving information input, such as a switch, keyboard, touch panel, microphone, or camera. The location information acquisition unit 180 is a device for acquiring location information, such as an antenna that receives signals transmitted from satellites constituting a Global Navigation Satellite System (GNSS), including a Global Positioning System (GPS).

[0020] 2(A), the information processing device 100 may be a device (for example, a drive recorder or a smartphone) attached to a moving body M such as a vehicle, or may be a server device installed outside the moving body M that communicates with a device O attached to the moving body M, as shown in FIG. 2(B). When the information processing device 100 is a server device installed outside the moving body that communicates with a device attached to the moving body, the information processing device 100 does not need to include the acceleration sensor 130, the call unit 140, the image data acquisition unit 150, the output unit 160, the input unit 170, and the position information acquisition unit 180.

[0021] When the information processing device 100 is a device O attached to a mobile object, the information processing device 100 may be configured to include a beacon and a smartphone. In this case, for example, the beacon may have an acceleration sensor 130, and the smartphone may have a communication unit 120, a call unit 140, an image data acquisition unit 150, an output unit 160, an input unit 170, and a location information acquisition unit 180. With regard to the functions of the control unit 110, the beacon may have some of the functions, and the smartphone may have the remaining functions.

[0022] 3 is a diagram showing the control unit 110. The control unit 110 has an acceleration acquisition processing unit 1101, an impact detection unit 1102, a drop detection unit 1103, and an impact cause determination unit 1104.

[0023] The acceleration acquisition processing unit 1101 acquires acceleration measured by an acceleration sensor of a device attached to a mobile object. For example, when the information processing device 100 is a device attached to a mobile object, the acceleration acquisition processing unit 1101 acquires acceleration measured by the acceleration sensor 130. On the other hand, when the information processing device 100 is a server device installed outside the mobile object that communicates with the device attached to the mobile object, the acceleration acquisition processing unit 1101 acquires acceleration measured by the acceleration sensor of the device attached to the mobile object by communicating using the communication unit 120.

[0024] Hereinafter, the acceleration sensor of the device attached to the mobile body will be referred to as the “on-vehicle acceleration sensor.” When the information processing device 100 is a device attached to the mobile body, the on-vehicle acceleration sensor is the acceleration sensor 130. When the information processing device 100 is a server device installed outside the mobile body that communicates with the device attached to the mobile body, the on-vehicle acceleration sensor is the acceleration sensor provided in the device attached to the mobile body.

[0025] The impact detection unit 1102 detects the occurrence of an impact on the in-vehicle acceleration sensor based on the acceleration acquired by the acceleration acquisition processing unit 1101. For example, if the information processing device 100 is a device attached to a mobile object, the impact detection unit 1102 detects the occurrence of an impact on the acceleration sensor 130, i.e., the occurrence of an impact on the information processing device 100. On the other hand, for example, if the information processing device 100 is a server device installed outside the mobile object that communicates with a device attached to the mobile object, the impact detection unit 1102 detects the occurrence of an impact on the acceleration sensor of the device attached to the mobile object, i.e., the occurrence of an impact on the device attached to the mobile object. The impact detection unit 1102 determines that an impact has occurred, for example, when the magnitude of the acceleration acquired by the acceleration acquisition processing unit 1101 exceeds a predetermined value.

[0026] The fall detection unit 1103 detects the occurrence of a fall of the in-vehicle acceleration sensor. For example, if the information processing device 100 is a device attached to a mobile object, the fall detection unit 1103 detects the occurrence of a fall of the acceleration sensor 130, that is, the occurrence of a fall of the information processing device 100. On the other hand, for example, if the information processing device 100 is a server device installed outside the mobile object that communicates with a device attached to the mobile object, the fall detection unit 1103 detects the occurrence of a fall of the acceleration sensor of the device attached to the mobile object, that is, the occurrence of a fall of the device attached to the mobile object.

[0027] The impact cause determination unit 1104 determines the cause of an impact detected by the impact detection unit 1102. When the in-vehicle acceleration sensor is dropped, it immediately collides with an object such as a dashboard, causing an impact on the in-vehicle acceleration sensor. Therefore, an impact detected immediately after the in-vehicle acceleration sensor is considered to be an impact caused by the drop of the in-vehicle acceleration sensor. Therefore, in this embodiment, if the drop of the in-vehicle acceleration sensor is detected immediately before the occurrence of the impact, the impact cause determination unit 1104 determines that the cause of the impact is the drop of the in-vehicle acceleration sensor. For example, if the drop of the in-vehicle acceleration sensor is detected within a predetermined time before the occurrence of the impact, the impact cause determination unit 1104 determines that the cause of the impact is the drop of the in-vehicle acceleration sensor.

[0028] In this way, in this embodiment, it is possible to determine whether the cause of the detected impact is the drop of the vehicle-mounted acceleration sensor. Therefore, for example, by not reporting to the outside when the impact is due to the drop of the vehicle-mounted acceleration sensor, it is possible to reduce unnecessary reports.

[0029] A large acceleration caused by a cause other than a drop in the in-vehicle acceleration sensor is likely to be caused by an impact due to an accident involving the moving object. Therefore, for example, if the impact cause determination unit 1104 does not detect a drop in the in-vehicle acceleration sensor immediately before the occurrence of the impact, it may be configured to determine that the cause of the impact is an accident involving the moving object.

[0030] <Fall detection> Figure 4 is a diagram showing the change in the magnitude of acceleration when a device attached to a mobile object is dropped. In Figure 4, the horizontal axis represents time, and the vertical axis represents the magnitude of acceleration. In Figure 4, the drop begins at time tA, and at time tB, the device collides with an object such as a dashboard, causing an impact. Between time tA and time tB, the device attached to the mobile object falls freely, so the magnitude of the acceleration approaches a value due to the acceleration of gravity g.

[0031] Therefore, the drop detection unit 1103 of the control unit 110 of the information processing device 100 according to an embodiment of the present invention detects the occurrence of a drop of the in-vehicle acceleration sensor based on the magnitude of acceleration acquired by the acceleration acquisition processing unit 1101. For example, if the period during which the magnitude of the acceleration is close to the gravitational acceleration g is equal to or greater than a predetermined threshold, the drop detection unit 1103 determines that the in-vehicle acceleration sensor has fallen during this period. Therefore, in this embodiment, it is possible to accurately detect the occurrence of a drop of the in-vehicle acceleration sensor.

[0032] The information processing device 100 may include an image data acquisition processing unit 1105 that acquires image data of the periphery of the in-vehicle acceleration sensor (i.e., the periphery of the device attached to the moving object). The drop detection unit 1103 may detect the occurrence of a drop of the in-vehicle acceleration sensor based on the magnitude of acceleration acquired by the acceleration acquisition processing unit 1101 and the image data acquired by the image data acquisition processing unit 1105. This makes it possible to detect the occurrence of a drop of the in-vehicle acceleration sensor based not only on a change in the magnitude of acceleration but also on a change in the scenery around the acceleration sensor (for example, a change in the position of the windshield window frame, etc.). As a result, it becomes possible to more accurately detect the occurrence of a drop of the in-vehicle acceleration sensor.

[0033] The drop detection unit 1103 may be configured to constantly detect the occurrence of a drop of the in-vehicle acceleration sensor, or may be configured to detect the occurrence of a drop of the in-vehicle acceleration sensor only when the impact detection unit 1102 detects the occurrence of an impact.

[0034] For example, when the occurrence of an impact is detected by the impact detection unit 1102, the drop detection unit 1103 may detect the occurrence of a drop of the on-board acceleration sensor based on the magnitude of acceleration measured by the on-board acceleration sensor before the occurrence of the impact. In this way, it becomes unnecessary to constantly detect the occurrence of a drop of the on-board acceleration sensor.

[0035] If the information processing device 100 is a server device installed outside the mobile device that communicates with a device attached to the mobile device, the control unit 110 does not need to include the impact detection unit 1102. In this case, it is preferable that the device attached to the mobile device has the function of the impact detection unit 1102. When the device attached to the mobile device detects an impact on the in-vehicle acceleration sensor, it transmits information indicating that an impact has been detected to the information processing device 100. When the drop detection unit 1103 of the information processing device 100 receives the information indicating that an impact has been detected via the communication unit 120, it detects that the in-vehicle acceleration sensor has been dropped based on the magnitude of acceleration measured by the in-vehicle acceleration sensor before the impact occurred, and the impact cause determination unit 1104 determines the cause of the impact.

[0036] <External reporting> If the cause of the impact is an accident, the information processing device 100 automatically reports to the outside, which enables a request for rescue from the occupants of the mobile body and storage of information related to the accident in an external device. Therefore, the control unit 110 of the information processing device 100 according to an embodiment of the present invention further includes a report processing unit 1106 that reports to the outside. Then, if it is determined that the cause of the impact is an accident of the mobile body, the report processing unit 1106 automatically reports.

[0037] The notification to the outside by the notification processing unit 1106 may include, for example, transmission of image data before and after the impact, and information (accident information) such as position information, speed information, and acceleration information of the moving object to an external device. At this time, for example, as shown in Fig. 5, the notification processing unit 115 transmits the accident information to the external device via the communication unit 120. This makes it possible for the external device to transmit the accident information to a rescue organization or the like, store the accident information, and analyze the cause of the accident based on the accident information.

[0038] Furthermore, the notification to the outside by the notification processor 1106 may include a call to a call center by a call unit of a device attached to the mobile body where the impact occurred. In this case, for example, as shown in FIG. 6, the notification processor 1106 calls the call center by a call unit of a device attached to the mobile body where the impact occurred. When the information processing device 100 is a device attached to the mobile body, the notification processor 1106 calls the call center by a call unit 140, as shown in FIG. 6(A). On the other hand, when the information processing device 100 is a server device installed outside the mobile body that communicates with a device O attached to the mobile body M, for example, the notification processor 1106 calls the call center by a call unit of the device O attached to the mobile body M by communicating using a communication unit 120, as shown in FIG. 6(B). This allows the driver of the mobile body to talk to an operator at the call center.

[0039] If the cause of the impact is the drop of the in-vehicle acceleration sensor, it is not necessarily necessary to report to the outside. Therefore, in this embodiment, if it is determined that the cause of the impact is the drop of the in-vehicle acceleration sensor, the report processing unit 1106 does not automatically report.

[0040] Therefore, in this embodiment, it is possible to reduce unnecessary notifications. Furthermore, when the notification to the outside includes transmission of accident information to an external device, the accident information is not transmitted to the external device, and unnecessary communication can also be reduced. In particular, when the information processing device 100 is a device attached to a mobile body, the accident information is not transmitted to the external device at all, and unnecessary communication can be further reduced.

[0041] Even if the cause of the impact is a drop of the in-vehicle acceleration sensor, there may be cases where it is necessary to report the event to an external device. Therefore, the report processing unit 1106 may transmit information indicating that the in-vehicle acceleration sensor has been dropped to an external device.

[0042] The control unit 110 may further include a confirmation information output processing unit 1107 and a response information acquisition processing unit 1108 .

[0043] If it is determined that the cause of the impact is a drop of the in-vehicle acceleration sensor, the confirmation information output processing unit 1107 outputs confirmation information including information regarding confirmation as to whether to issue a report. At this time, if the information processing device 100 is a device attached to a mobile object, the confirmation information output processing unit 1107 outputs the confirmation information, for example, via the output unit 160. On the other hand, if the information processing device 100 is a server device installed outside the mobile object that communicates with the device attached to the mobile object, the confirmation information output processing unit 1107 outputs the confirmation information via an output device (for example, a display or speaker) of the device attached to the mobile object, for example, by communicating using the communication unit 120.

[0044] The response information acquisition processing unit 1108 acquires response information including information related to a response to the confirmation as to whether to make a report. At this time, if the information processing device 100 is a device attached to a mobile object, the response information acquisition processing unit 1108 acquires, for example, the response information input by the input unit 170. On the other hand, if the information processing device 100 is a server device installed outside the mobile object that communicates with the device attached to the mobile object, the response information acquisition processing unit 1108 acquires, for example, the response information input by an input device (for example, a switch, keyboard, touch panel, microphone, or camera) of the device attached to the mobile object by performing communication using the communication unit 120.

[0045] If the response to the confirmation as to whether to make a report includes a predetermined response, the report processing unit 1106 makes a report according to the response. In this way, when it is determined that the cause of the impact is a drop of the in-vehicle acceleration sensor, it is possible to make a report to the outside after confirming with the user whether to make a report.

[0046] For example, if the response includes "do not report," the report processing unit 1106 may not report to the outside. Alternatively, if the response includes "report," the report processing unit 1106 may report to the outside. Alternatively, if the response includes "send information about the impact," the report processing unit 1106 may transmit images of the vehicle before and after the impact, as well as information about the vehicle's position, speed, and acceleration, to an external device. Alternatively, if the response includes "make a call," the report processing unit 1106 may make a call to a call center using a call unit of a device attached to the vehicle where the impact occurred.

[0047] The confirmation information may also be configured to output information regarding confirmation of whether or not the vehicle has fallen. The response information may include information regarding a response to the confirmation of whether or not the vehicle has fallen, and if the response to the confirmation of whether or not the vehicle has fallen includes a predetermined response, the report processing unit 1106 may issue a report according to the response. For example, if the response includes a response of "it has fallen," the report processing unit 1106 may transmit information indicating that the vehicle acceleration sensor has fallen to an external device. If the response includes a response of "it has not fallen" or if there is no response, there is a possibility that an accident has occurred with the mobile object. Therefore, if the response includes a response of "it has not fallen" or if there is no response, the report processing unit 1106 may issue a report to an external device.

[0048] <Request to replace mounting parts> The mounting condition of a device attached to a mobile object (i.e., a device equipped with an in-vehicle acceleration sensor) may deteriorate, and even if the device is reattached to the mobile object, the device may repeatedly fall off. In such a case, it is better to replace the attached parts. Therefore, the control unit 110 of the information processing device 100 according to an embodiment of the present invention further includes a message output processing unit 1109.

[0049] If repeated occurrences of dropping of a device attached to a mobile object are detected, the message output processing unit 1109 outputs information related to a message urging the user to replace the attachment parts for attaching the device to the mobile object. At this time, if the information processing device 100 is a device attached to the mobile object, the message output processing unit 1109 outputs a message urging the user to replace the attachment parts, for example, via the output unit 160. On the other hand, if the information processing device 100 is a server device installed outside the mobile object that communicates with the device attached to the mobile object, the confirmation information output processing unit 1107 outputs a message urging the user to replace the attachment parts, for example, via an output device (e.g., a display or speaker) of the device attached to the mobile object, by communicating using the communication unit 120. The message output processing unit 1109 may also be configured to send an email urging the user of the mobile object (e.g., the owner or manager of the mobile object) to replace the attachment parts, via the communication unit 120.

[0050] In this way, in this embodiment, when the attachment condition of a device attached to a mobile object deteriorates, it is possible to prompt the user of the mobile object to replace the attachment member. Therefore, in this embodiment, it is possible to reduce the risk of the device attached to the mobile object falling. As a result, it is possible to reduce the detection of impacts caused by falling of an acceleration sensor attached to the mobile object, and it is possible to reduce unnecessary notifications.

[0051] For example, the message output processing unit 1109 determines that the device has repeatedly been dropped when the in-vehicle acceleration sensor detects a drop a predetermined number of times within a predetermined period. The predetermined period may be determined based on the usage status of the vehicle. This makes it possible to determine the degree of deterioration of the mounting member depending on the usage status of the vehicle.

[0052] For example, the measurement history of an in-vehicle acceleration sensor can be used to determine the time period during which the mobile object is in use. Therefore, it is preferable to determine the usage status of the mobile object based on the measurement history of the in-vehicle acceleration sensor.

[0053] Furthermore, it is also possible to know the time when the mobile object is being used by using information about the location of the mobile object. Therefore, the information processing device 110 may further include a mobile object location information acquisition processing unit 1110 that acquires mobile object location information including information about the location of the mobile object, and the usage status of the mobile object may be determined based on this mobile object location information. For example, if the information processing device 100 is a device attached to the mobile object, the mobile object location information acquisition processing unit 1110 acquires the mobile object location information using the location information acquisition unit 180. On the other hand, if the information processing device 100 is a server device installed outside the mobile object that communicates with the device attached to the mobile object, the mobile object location information acquisition processing unit 1110 acquires the mobile object location information using the location information acquisition unit of the device attached to the mobile object by communicating using the communication unit 120.

[0054] Generally, an in-vehicle device such as a drive recorder is activated by turning on the accessory power supply (ACC power supply) of the vehicle. In other words, it is possible to know the time period during which the vehicle is in use by using information related to the activation of the device attached to the vehicle. Therefore, the information processing device 110 may further include a device activation information acquisition processing unit 1111 that acquires device activation information including information related to the activation of the device attached to the vehicle, and the usage status of the vehicle may be determined based on this device activation information.

[0055] 7, the control unit 110 of the information processing device 100 may have a fall information acquisition processing unit 1112 that acquires information about the occurrence of a fall of the acceleration sensor from another device (for example, a device attached to a mobile object) using communication by the communication unit 120, instead of the fall detection unit 1103. Then, the message output processing unit 1109 may determine whether the fall of the acceleration sensor has been repeatedly detected based on the information about the occurrence of a fall of the acceleration sensor. In this way, the information processing device 100 does not need to have a function for detecting the occurrence of a fall of the in-vehicle acceleration sensor.

[0056] <Processing Operation in Control Unit 110> 8 shows an example of a processing operation executed by the control unit 110 when the occurrence of an impact is detected. The impact cause determination unit 1104 checks whether a drop of the in-vehicle acceleration sensor has been detected immediately before the impact (step S801).

[0057] If a drop of the vehicle-mounted acceleration sensor is detected immediately before the impact (step S801, YES), the impact cause determination unit 1104 determines that the cause of the impact is the drop of the vehicle-mounted acceleration sensor, and the confirmation information output processing unit 1107 outputs confirmation information including information regarding whether to make a report (step S802).

[0058] If the response information acquisition processing unit 1108 does not acquire response information including information regarding a response to the confirmation as to whether to issue a report within a predetermined time (step S803, NO), the processing ends. If the response information acquisition processing unit 1108 acquires response information including information regarding a response to the confirmation as to whether to issue a report (step S803, YES), the report processing unit 1106 checks whether the response includes a predetermined response (step S804).

[0059] If the response includes a predetermined response (step S804, YES), the notification processing unit 1106 issues a notification to the outside (step S805). If the response does not include a predetermined response (step S504, NO), the process ends.

[0060] If a fall of the vehicle-mounted acceleration sensor is not detected immediately before the impact (step S801, NO), the impact cause determination unit 1104 determines that the cause of the impact is an accident involving a moving object, and the notification processing unit 1106 issues a notification to the outside (step S806).

[0061] The present invention has been described above in terms of preferred embodiments thereof. While the present invention has been described herein with reference to specific examples, various modifications and variations can be made to these examples without departing from the spirit and scope of the present invention as set forth in the claims.
