[Displacement detection processing]
FIG. 10 is a sequence diagram showing an example of the flow of processing for detecting the displacement of the relative position of the moving body executed by the moving body. In this process, the process performed by the motorcycle will be described, but for example, the vehicle or the lawn mower also performs the process in the same manner.

First, the second communication unit 14-2 of the motorcycle transmits a first signal for starting communication to the lawn mower (step S100). Next, when the second communication unit 14-3 of the lawn mower receives the first signal, it transmits a second signal indicating that the communication has been established to the motorcycle (step S102). Next, when the motorcycle control unit 18-2 receives the second signal, it recognizes that communication with the lawn mower has been established (step S104). When short-range wireless communication between the motorcycle and the lawn mower is established in this way, the motorcycle recognizes that the lawn mower is near the motorcycle, and the relative position between the lawn mower and the motorcycle is displaced. Judge that it is not.

The motorcycle executes the processes described in steps S100 to S104 above with the vehicle (steps S106 to S110). For example, when the control unit 18-2 of the motorcycle tries to communicate with the vehicle but cannot receive the second signal from the vehicle (when it wants to be able to receive the signal until a predetermined time but cannot receive it), the motorcycle and the control unit 18-2 are connected to the motorcycle. It is determined that the position relative to the vehicle is displaced (step S112). Then, the control unit 18-2 of the motorcycle transmits a displacement notification indicating that the relative position between the motorcycle and the vehicle has been displaced to the notification device 100 (step S114).

FIG. 11 is a diagram showing an example of information generated by the motorcycle communicating with the vehicle and the lawn mower. For example, the bike communicates with the vehicle and the lawnmower at predetermined intervals to determine if a relative displacement has occurred. For example, if the motorcycle cannot communicate with the vehicle at time T + 10, a displacement notification is transmitted to the notification device 100.

FIG. 12 is a diagram showing an example of a state in which the relative position of the moving body is not displaced. For example, if the vehicle, motorbike, and lawnmower are maintained in their home garage or other predetermined position as shown, the displacement notification will not be transmitted to the notification device 100.

FIG. 13 is a diagram showing an example of a state in which the relative position of the moving body is displaced. For example, when the vehicle moves from a predetermined position to a different position among vehicles, motorcycles, and lawnmowers as shown in the figure, a displacement notification is transmitted to the notification device 100.

When the notification device 100 receives the displacement notification, the notification device 100 may notify the terminal device 200 of the administrator of the mobile body regarding the theft. Further, the notification device 100 may execute the following processing.

The notification control unit 108 of the notification device 100 is relative when the relative position of the moving body is displaced while the authentication management unit 106 has not authenticated the use of the moving body whose relative position is displaced among the plurality of moving bodies. By notifying the user of the moving object whose position has been displaced, it is possible to more effectively contribute to the suppression of theft.

FIG. 14 is a flowchart showing an example of the flow of processing executed by the notification device 100. The determination conditions in steps S202, S204, or S206 are examples of notification conditions.

First, the position information management unit 104 of the notification device 100 determines whether or not the displacement notification has been received (step S200). When the displacement notification is received, the authentication management unit 106 of the notification device 100 determines whether or not the specific conditions regarding the administrator and the moving body are satisfied (step S202). When the specific condition is satisfied, the processing of one routine of this flowchart ends.

If the specific condition is not satisfied, the process proceeds to step S204. The specific condition is, for example, that the terminal device 200 of the administrator authenticates with the mobile body. In this case, it is presumed that the administrator is using the mobile body. FIG. 15 is a diagram showing an example of a scene satisfying a specific condition.

Further, the specific condition may be that the distance between the administrator's terminal device 200 and the moving body is within the first distance, instead of (or in addition to) the above condition. FIG. 16 is a diagram showing an example of a case where the position of the terminal device 200 exists within the first distance from the position of the moving body (vehicle). For example, when the vehicle moves and the relative position changes, and the position of the vehicle and the position of the terminal device 200 are within the first distance, the notification device 100 sends the notification information regarding the theft to the user terminal device 200. Do not send. This is because the user is in the vehicle or the vehicle is moving within the monitoring range of the user.

Here, an example of a process in which the notification device 100 acquires the position of the moving body will be described. The moving body may perform one or more of the following processes to transmit the position information to the notification device 100.
(11) The moving body transmits its own position information to the notification device 100 at predetermined intervals or when transmitting the displacement notification.
(12) When the notification device 100 obtains the displacement notification, the notification device 100 requests the moving body to transmit the position information. In response to this request, the moving body transmits its own position information to the notification device 100. In this case, the notification device 100 may request the moving body whose position has been displaced to transmit the position information. For example, the notification device 100 estimates that among the moving bodies that have transmitted the displacement notification, the moving body (vehicle) that could not communicate with other moving bodies (motorcycle, lawnmower) is a moving body whose position has been displaced.

As described above, the notification control unit 108 uses the moving body and the terminal device 200 based on the relative positions of one or more moving bodies among the plurality of moving bodies and the terminal device 200 associated with the one or more moving bodies. When the distance to and from is within the first predetermined distance, one or more movements are made even if the relative positions of a plurality of moving bodies are displaced in a state where the authentication management unit 106 has not authenticated the use of the moving body. Do not send notification information to the terminal device 200 (or the terminal device associated with the mobile) of the body user. As a result, unnecessary notifications are suppressed.

Further, in the notification device 100, if the position of the moving body is displaced within a predetermined time after the authentication between the terminal device 200 and the moving body is established, the moving body and the administrator are acting together. It is not necessary to transmit the notification information regarding the theft by assuming that the position of the terminal device 200 of the administrator exists within the first distance from the position of the moving body.

Returning to the description of the flowchart of FIG. If the specific condition is not satisfied in step S202, the authentication management unit 106 of the notification device 100 refers to the usage management information 126 and determines whether or not the rental of the mobile body whose position has been displaced is reserved. (Step S204).

When the rental of the mobile body whose position has been displaced has not been reserved, the notification control unit 108 of the notification device 100 transmits the notification information regarding the theft to the terminal device 200 of the administrator using the communication unit 102 (step S208). ). When the rental of the moving body whose position has been displaced is reserved, the notification control unit 108 of the notification device 100 determines whether or not the specific conditions regarding the rental user and the moving body are satisfied (step S206). When this specific condition is satisfied, the processing of one routine of this flowchart ends. If this specific condition is not satisfied, the process proceeds to step S208. The specific condition regarding the rental user and the mobile body is, for example, that the terminal device 200 of the administrator authenticates with the mobile body. In this case, it is presumed that the rental user is using the mobile body.

Further, the specific condition regarding the rental user and the moving body may be that the distance between the user terminal device and the moving body exists within the second distance instead of (or in addition to) the above condition.

As described above, the notification control unit 108 moves based on the relative position between one or more mobiles among the plurality of mobiles and the user terminal device authorized by the administrator of the one or more mobiles. When the distance between the body and the user terminal device is within the second predetermined distance, even if the relative positions of the plurality of moving bodies are displaced in a state where the authentication management unit 106 has not authenticated the use of the moving body. , Do not send notification information to the terminal device 200 of the mobile user. As a result, unnecessary notifications are suppressed. It is assumed that the position information of the moving body and the position information of the user terminal device of the user who rents the moving body are transmitted to the notification device 100 at predetermined intervals from a predetermined timing.

FIG. 17 is a diagram for explaining a process when the rental of the moving body whose position has been displaced is not reserved. As shown in the figure, when the rental reservation of the vehicle whose position has been displaced is not made, the notification device 100 transmits the notification information regarding the theft to the terminal device 200 of the administrator. As a result, the manager can recognize that the position of the vehicle has been displaced even though the rental of the vehicle has not started.

FIG. 18 is a diagram for explaining processing when a reservation for renting a moving body whose position has been displaced is made and a specific condition is satisfied. As shown in the figure, when a rental reservation of a vehicle whose position has been displaced is made and a specific condition is satisfied, the notification device 100 transmits information regarding the rental to the administrator terminal device 200. As a result, the manager can recognize that the rental of the vehicle has started.

According to the first embodiment described above, the relative positions of the plurality of moving bodies are displaced when the notification device 100 is not certified for the use of the moving body whose relative position is displaced at least among the plurality of moving bodies. In this case, the communication unit 102 can be used to transmit the notification information to the terminal device 200 of the mobile user, thereby more effectively contributing to the suppression of theft.

<Second Embodiment>
Hereinafter, the second embodiment will be described. In the second embodiment, the notification device 100 determines the displacement of the relative position of the moving body. Hereinafter, the differences from the first embodiment will be mainly described.

FIG. 19 is a sequence diagram showing an example of a flow of processing for detecting a displacement of a relative position of a moving body executed by the moving body in the second embodiment. Since the processing of steps S100A to S110A is the same as the processing of steps S100A to S110A of FIG. 10, the description thereof will be omitted. For example, when the motorcycle attempts to communicate with the vehicle but cannot receive the second signal from the vehicle, it transmits information indicating that it could not communicate with the vehicle to the notification device 100 (step S112A). Then, the notification device 100 recognizes that the relative position between the motorcycle and the vehicle has been displaced based on the information transmitted in step S112A (step S114A).

According to the second embodiment described above, the same effect as that of the first embodiment is obtained.

<Third Embodiment>
Hereinafter, the third embodiment will be described. In the third embodiment, when the moving body deviates from the formed geofence, it is determined that the displacement exists at the relative position of the moving body. Hereinafter, the differences from the first embodiment will be mainly described.

FIG. 20 is a diagram showing an example of the contents of the user information 124A of the third embodiment. The user information 124A is information in which geofence information and reference position information of a moving body (vehicle, motorcycle, lawn mower) are associated with the user information 124. The moving body reference position information (set position) is a position registered in advance and is information registered by the administrator as a fixed position of the moving body. The distance between each movement reference position information is less than or equal to a predetermined distance (several meters, ten to twenty meters).

The geofence information is information generated based on the moving body reference position information. For example, when the administrator determines the mobile reference position information and transmits the determination result to the notification device 100, the notification device 100 generates a geofence including the mobile reference position information based on the determination result. Note that geofence information may be generated based on the specifications of the administrator. For example, the geofence information may be generated by the administrator operating the terminal device 200 and designating the range of the geofence. In addition, the administrator walks in the range where the geofence is desired, and the position information when walking is transmitted to the notification device 100. Based on this information, the notification device 100 may generate geofence information. When the geofence information does not include the mobile reference position information, the notification device 100 may notify the administrator so that the geofence information includes the mobile reference position information.

FIG. 21 is a diagram for explaining geofence information. For example, the notification device 100 acquires the position information (first position) of the moving body when the relative position of the moving body is displaced. Further, the notification device 100 forms a geofence based on the moving body reference position information, and when the position information of the moving body deviates from the geofence, the notification device 100 transmits the notification information regarding the theft to the terminal device 200 of the administrator. To do.

According to the third embodiment described above, when the position of the moving body deviates from the geofence, the notification control unit 108 transmits the notification information to the manager of the moving body to obtain the same as the first embodiment. It has the same effect.

In each of the above embodiments, the notification device 100 may recognize the displacement of the relative position based on the position information acquired from the moving body including the positioning unit. Further, the moving body may recognize the displacement of the moving other based on the position information acquired from the other moving body.

Further, in each of the above embodiments, the mobile body recognizes the displacement of the relative position of the mobile body based on the communication result of the short-range wireless communication, but instead (or in addition), A camera or radar device may be used to recognize the displacement of the relative position of another moving object. For example, the moving body includes an image processing unit and a camera, and the image processing unit can analyze the image captured by the camera and recognize that another preset moving body exists at a predetermined position. In this case, it is recognized that the relative position of the moving body is not displaced. For example, the moving body includes an analysis unit and a radar device, and in the analysis, the radio wave emitted by the radar device and the reflected wave for the radio wave are analyzed, and another preset moving body exists at a predetermined position. If it can be recognized that it is, it is recognized that the relative position of the moving body is not displaced.

<Fourth Embodiment>
Hereinafter, the fourth embodiment will be described. In the fourth embodiment, the communication standards of the communication units included in the plurality of mobile bodies are different. Hereinafter, the differences from the first embodiment will be mainly described.

The notification system 1 of the fourth embodiment replaces (or additionally) the vehicle 10-1, the motorcycle 10-2, and the lawnmower 10-3, and the vehicle 10-1A (vehicle; an example of the third moving body). , Bike 10-2A (motorcycle; example of first moving body), and lawn mower 10-3A (lawn mower; example of second moving body). The "X communication unit 14-2X" described below is an example of the "first type communication unit of the first mobile body", and the "X communication unit 14-3X" is the "first type communication unit of the second mobile body". It is an example of the "communication unit", and the "Y communication unit 14-3Y" is an example of the "second type communication unit of the second mobile body". Further, "Y communication unit 14-1Y" is an example of "second type communication unit of the third mobile body", and "Z communication unit 12-1Z" is "third type communication unit of the third mobile body". Is an example. The communication units having the same type as described above may have different functions and configurations as long as they can communicate using the same communication method.

FIG. 22 is a diagram showing an example of the functional configuration of the vehicle 10-1A, the motorcycle 10-2A, and the lawn mower 10-3A. The vehicle 10-1A, the motorcycle 10-2A, and the lawn mower 10-3A do not have a communication unit that performs wireless communication according to a common communication standard, and perform wireless communication according to a communication standard common to some mobile objects. It has a communication unit. For example, the vehicle 10-1A has a communication unit that communicates with the lawn mower 10-3A and does not have a communication unit that communicates with the motorcycle 10-2A, and the motorcycle 10-2A communicates with the lawn mower 10-3A. It is not provided with a communication unit that communicates with the vehicle 10-1A. Further, the vehicle 10-1A uses a Z communication unit (corresponding to the first communication unit of the first embodiment) 12-1Z that communicates with the notification device 100 using the Z communication standard (an example of the "third communication standard"). The bike 10-2A and the lawn mower 10-3A do not have a communication unit that communicates with the notification device 100.

The vehicle 10-1A includes, for example, a Y communication unit 14-1Y in place of the second communication unit 14-1 of the first embodiment. The Y communication unit 14-1Y is, for example, a communication interface for performing wireless communication using a Y communication standard (an example of a "second communication standard"). The Z communication unit 12-1Z has the same functional configuration as the first communication unit 12-1 of the first embodiment.

The bike 10-2A includes, for example, an X communication unit 14-2X in place of the second communication unit 14-2 of the first embodiment. The X communication unit 14-2X is, for example, a communication interface for performing wireless communication using the X communication standard (an example of the "first communication standard"). In the motorcycle 10-2A, the first communication unit 12-2 is omitted.

The lawn mower 10-3A includes, for example, a Y communication unit 14-3Y and an X communication unit 14-3X in place of the second communication unit 14-2 of the first embodiment. The Y communication unit 14-3Y is, for example, a communication interface for performing wireless communication using the Y communication standard. The X communication unit 14-3X is, for example, a communication interface for performing wireless communication using the X communication standard. In the lawn mower 10-3A, the first communication unit 12-3 is omitted.

For example, the X communication standard and the Y communication standard are communication standards related to short-range wireless communication, and one of the X communication standard and the Y communication standard communicates using, for example, the first frequency (for example, 13.56 MHz). The other is a communication standard using, for example, a second frequency (eg 2.56 GHz). The Z communication standard is a communication standard (for example, wireless LAN) used by the Z communication unit 12-1Z, which is different from the X communication standard and the Y communication standard, in communication. The Z communication standard is, for example, a communication standard having higher communication performance than the X communication standard or the Y communication standard (for example, communication distance and communication speed). The Z communication standard may be the same communication standard as the X communication standard or the Y communication standard, or may be a communication standard having the same or lower communication performance than the X communication standard or the Y communication standard.

FIG. 23 is a diagram for explaining communication between mobile bodies. For example, the motorcycle 10-2A and the lawn mower 10-3A communicate using the X communication standard. The lawnmower 10-3 acquires information about the position of the bike 10-2A. The information regarding the position of the motorcycle 10-2A is, for example, information indicating the relative position of the motorcycle 10-2A with respect to the lawn mower 10-3 (hereinafter, motorcycle position information).

For example, the lawn mower 10-3A and the vehicle 10-1A communicate using the Y communication standard. Vehicle 10-1A acquires motorcycle position information from the lawnmower 10-3A. Further, the vehicle 10-1A acquires information regarding the position of the lawnmower 10-3A. The information regarding the position of the lawn mower 10-3A is, for example, information indicating the relative position of the lawn mower 10-3A with respect to the vehicle 10-1A (hereinafter, lawn mower position information).

Vehicle 10-1A transmits the motorcycle position information and the lawn mower position information to the notification device 100. The notification device 100 acquires the above-mentioned motorcycle position information and lawn mower position information, and further communicates with the vehicle 10-1A using the Z communication standard to acquire information on the position of the vehicle 10-1A. .. The information regarding the position of the vehicle 10-1A is, for example, information indicating the relative position of the vehicle 10-1A with respect to the notification device 100 (hereinafter, vehicle position information).

FIG. 24 is a diagram showing an example of a flow of processing for detecting a displacement of a relative position of a moving body executed by the moving body of the second embodiment. First, the X communication unit 14-3X of the lawn mower transmits a first communication signal for starting communication using the X communication standard to the motorcycle (step S300). Next, when the X communication unit 14-2X of the motorcycle receives the first communication signal, it transmits a second communication signal indicating that the communication has been established to the lawn mower (step S302). Next, when the control unit 18-3 of the lawn mower receives the second communication signal, it recognizes that communication with the motorcycle has been established (step S304). When short-range wireless communication between the motorcycle and the lawn mower is established in this way, the lawn mower acquires the motorcycle position information based on the communication result of the wireless communication. For example, the lawnmower acquires the relative position of the motorcycle based on the direction of the radio wave acquired from the motorcycle, the intensity of the radio wave, the phase of the radio wave, and the like. Then, the control unit 18-3 of the lawn mower transmits the motorcycle position information to the vehicle (step S306).

The vehicle executes the processes described in steps S300 to S304 with the lawn mower to acquire the lawn mower position information (steps S308 to S312). However, the vehicle and the lawn mower communicate using the Y communication standard. Then, the vehicle control unit 18-1 transmits the motorcycle position information and the lawn mower position information to the notification device 100 (step S314).

Next, the notification device 100 executes the processes described in steps S300 to S304 with the vehicle to acquire vehicle position information (steps S316 to S320). However, the vehicle and the notification device 100 communicate using the Z communication standard. Then, the notification device 100 obtains the motorcycle position information, the lawn mower position information, and the vehicle position information acquired in the past, and the motorcycle position information, the lawn mower position information, and the vehicle position information acquired by the above processing. By comparison, it is determined whether or not there is a displacement in these position information (step S322). It should be noted that the vehicle or other device compares the motorcycle position information or the lawnmower position information acquired in the past with the motorcycle position information or the lawnmower position information acquired by the above processing. It may be determined whether or not there is a displacement in the position information of. Further, the lawn mower may compare the motorcycle position information acquired in the past with the motorcycle position information acquired in the above process to determine whether or not there is a displacement in these position information. ..

According to the fourth embodiment described above, even when the communication standards of the communication units included in the plurality of mobile bodies are different, it is possible to contribute to the theft suppression easily and more effectively.
