DETAILED DESCRIPTION

[0035] [1. Structure of monitoring system]

[0036] Reference Signs Figures 1-3 The structure of the monitoring system 1 will be described. As shown in FIG. 1, the monitoring system 1 of the present embodiment is composed of the first vehicle 10 and the second vehicle 50. The first vehicle 10 corresponds to the first device and the first mobile body of the present application, and the second vehicle 50 corresponds to the second device, the second mobile body, and the monitoring device of the present application. Figure 1

[0037] The first vehicle 10 is provided with the first control unit 20, the first communication section 11, the sensor group 12, the camera 13, the sonar 14, the GNSS (Global Navigation Satellite System) sensor 15, the horn 16, and the light fixture 17. The first communication section 11 performs wireless communication in a communication range of several meters, for example, according to a communication specification for short distances such as BLE (Bluetooth Low Energy: Bluetooth is a registered trademark).

[0038] The sensor group 12 includes an acceleration sensor, a tilt sensor, a vibration sensor, a door opening / closing sensor, a door lock sensor, an ultrasonic sensor, and the like. The camera 13 captures the surroundings and the interior of the first vehicle 10. The sonar 14 detects objects present in the periphery of the first vehicle 10. The GNSS sensor 15 detects the current position of the first vehicle 10. The horn 16 outputs a warning sound. The light fixture 17 includes a headlight, a small light, a tail light, a brake light, and the like.

[0039] ​The first control unit 20 performs wireless communication with other vehicles such as the second vehicle 50, communication terminals, and the like via the first communication section 11. The detection signals of the sensor group 12, the photographed images of the camera 13, the object detection information detected by the sonar 14, and the detection information of the current position of the first vehicle 10 detected by the GNSS sensor 15 are input to the first control unit 20. The operation of the horn 16 and the light fixture 17 is controlled in accordance with the control signal output from the first control unit 20.

[0040] The first control unit 20 is configured by a first processor 30, a first memory 40, an interface circuit not shown, and the like, and the first memory 40 stores therein a first program 41 for controlling the operation of the first control unit 20 and a first slot 42 in which the unique code of the communication object of the first communication section 11 is recorded. The first processor 30 reads and executes the first program 41, thereby functioning as a first monitoring mode setting section 31, a first abnormality occurrence recognition section 32, and a first notification control section 33. The processes performed by the first monitoring mode setting section 31, the first abnormality occurrence recognition section 32, and the first notification control section 33 will be described later.

[0041] Like the first vehicle 10, the second vehicle 50 is provided with a second control unit 60, a second communication section 51, a sensor group 52, a camera 53, a sonar 54, a GNSS sensor 55, a horn 56, and a light fixture 57. The functions of the second communication section 51, the sensor group 52, the camera 53, the sonar 54, the GNSS sensor 55, the horn 56, and the light fixture 57 are the same as those of the first communication section 11, the sensor group 12, the camera 13, the sonar 14, the GNSS sensor 15, the horn 16, and the light fixture 17 of the first vehicle 10 described above, respectively, and thus the description thereof is omitted.

[0042] The second control unit 60 is configured by a second processor 70, a second memory 80, an interface circuit not shown, and the like, and the second memory 80 stores therein a second program 81 for controlling the operation of the second control unit 60 and a second slot 82 in which the unique code of the communication object of the second communication section 51 is recorded. The second processor 70 reads and executes the second program 81, thereby functioning as a second monitoring mode setting section 71, a second abnormality occurrence recognition section 72, and a second notification control section 73. The processes performed by the second monitoring mode setting section 71, the second abnormality occurrence recognition section 72, and the second notification control section 73 will be described later.

[0043] [2. Monitoring processes in the first vehicle and the second vehicle]

[0044] With reference to Figures 4-7 , the monitoring processes performed in the first vehicle 10 and the second vehicle 50 will be described with reference to the flowcharts shown in Figures 2-3 .

[0045] [2-1. Monitoring Processing in Vehicle 1]

[0046] First, according to Figure 2 The flowchart shown illustrates the processing performed by the first monitoring mode setting unit 31 on the side of the first vehicle 10. Figure 2 In step S1, when the first monitoring mode setting unit 31 detects that the door of the vehicle 10 has been locked using a portable key or the like, the process proceeds to step S2. Step S1 is a process for recognizing that the use of the first vehicle 10 has ended and the user of the first vehicle 10 has left the parked vehicle 10. In addition to the door locking operation using a portable key, the user can also be identified by the image captured by the camera 13.

[0047] In the next step S2, the first monitoring mode setting unit 31 sends a response request message containing the vehicle's unique code of the first vehicle 10 through the first communication unit 11 to search for other vehicles parked near the first vehicle 10 that are capable of short-range wireless communication. In the next step S3, when a response is received from another vehicle, the first monitoring mode setting unit 31 causes the process to proceed to step S4.

[0048] On the other hand, when there is no response from other vehicles (no response information is received), the first monitoring mode setting unit 31 causes the process to proceed to step S20, determining whether the door of the first vehicle 10 has been unlocked using a portable key or the like. Then, if the door unlocking operation has been performed (when the first vehicle 10 is used again), the first monitoring mode setting unit 31 causes the process to proceed to step S11, in which case the processing on the first vehicle 10 side ends. Furthermore, if the door unlocking operation has not been performed, the first monitoring mode setting unit 31 causes the process to proceed from step S20 to step S2.

[0049] In step S4, the first monitoring mode setting unit 31 selects the other responding vehicle as the second vehicle 50, identifies the vehicle-specific code of the second vehicle 50 contained in the response information, and sends a pairing request message to the second vehicle 50, thus performing pairing between the first vehicle 10 and the second vehicle 50. Here, before pairing is completed, as... Figure 4 As shown, the three slots C1 to C3 of the first slot 42 of the first vehicle 10 and the three slots C1 to C3 of the second slot 82 of the second vehicle 50 are all in an idle state.

[0050] In the paired state, such as Figure 5As shown, the vehicle inherent code "12345" of the second vehicle 50 as the pairing counterpart is written in the slot C1 of the first slot 42 of the first vehicle 10. Further, the vehicle inherent code "98765" of the first vehicle 10 as the pairing counterpart is written in the slot C1 of the second slot 82 of the second vehicle 50.

[0051] The first slot 42 and the second slot 82 are provided with three slots C1 to C3, and thus the first vehicle 10 and the second vehicle 50 can perform pairing with one to three other vehicles and execute the monitoring process. The number of slots can also be two or less, or four or more.

[0052] The first monitoring mode setting section 31 sets the first vehicle 10 to the monitoring mode in the next step S5, and transmits the monitoring mode setting information to the second vehicle 50 in step S6. Through the loop process of the following step S7 and step S8, the first monitoring mode setting section 31 executes the first abnormality recognition process based on the first abnormality occurrence recognition section 32 and the first notification control section 33 in step S7 until the door unlocking operation of the first vehicle 10 is recognized in step S8.

[0053] The first abnormality occurrence recognition section 32 recognizes the occurrence of an abnormality (theft, damage to the vehicle, or the like) of the first vehicle 10 when at least any one of the following (1-1) to (1-4) is satisfied.

[0054] (1-1) When the wireless communication between the first communication section 11 and the second communication section 51 is cut off.

[0055] (1-2) When the radio wave intensity (measured based on RSSI or the like) of the wireless communication between the first communication section 11 and the second communication section 51 becomes a prescribed intensity or less.

[0056] (1-3) When the distance between the first vehicle 10 and the second vehicle 50 becomes a prescribed distance or less. The first abnormality occurrence recognition section 32 calculates the distance between the first vehicle 10 and the second vehicle 50 based on the current position of the first vehicle 10 detected by the GNSS sensor 15 and the information of the current position of the second vehicle 50 detected by the GNSS sensor 55 and transmitted from the second vehicle 50. Alternatively, the first abnormality occurrence recognition section 32 can recognize the distance between the first vehicle 10 and the second vehicle 50 based on the detected position information of the second vehicle 50 detected by the sonar 14 and the photographed image of the second vehicle 50 captured by the camera 13.

[0057] (1-4) When the sensor group 12 has detected a signal indicating an abnormality of the first vehicle 10, the camera 13 has captured an image indicating an abnormality of the first vehicle 10. The first abnormality occurrence recognition unit 32 recognizes the occurrence of an abnormality of the first vehicle 10, for example, when the acceleration sensor has detected an acceleration of a prescribed level or more, when the vibration sensor has detected a vibration of a prescribed level or more, when the tilt sensor has detected a tilt of a prescribed level or more, when the ultrasonic sensor has detected a displacement of an object in the vehicle cabin, when an unlocking operation of the door has been detected in a state in which authentication by the portable key or the like is not possible, or when a suspicious person other than the user whose face image is stored in the first memory 40 has been recognized in the captured image of the camera 13 as being present in the vicinity of or in the vehicle cabin of the first vehicle 10.

[0058] When the determination condition of (1-4) above is satisfied, the first abnormality occurrence recognition unit 32 transmits abnormality detection information to the second vehicle 50. The first notification control unit 33 causes the horn 16 or the lamp 17 to operate and notifies the surroundings of the first vehicle 10 when the first abnormality occurrence recognition unit 32 has recognized the occurrence of an abnormality of the first vehicle 10. In this case, the manner of notification by the horn 16 and the lamp 17 can also be changed in accordance with the content of the abnormality that has occurred in the first vehicle 10.

[0059] Here, Figure 6 A11 shows a state in which the first vehicle 10 has been lifted and stolen. Figure 6 A11 shows a state in which the first vehicle 10 has been lifted and stolen.

[0060] As shown in A12 of FIG. 10, the determination conditions of (1-2) and (1-3) above are also satisfied when the first vehicle 10 has been separated from the second vehicle 50 due to theft. Also, as in the case in which the determination condition of (1-1) above is satisfied, the first notification is performed in the first vehicle 10 and the second notification is performed in the second vehicle 50. Figure 6

[0061] A12 shows a state in which the first vehicle 10 has been lifted and stolen. Figure 7 A12 shows a state in which the first vehicle 10 has been lifted and stolen.Figure 7 A21 illustrates a situation where a suspicious person T approaches vehicle 10 while wireless communication between vehicle 10 and vehicle 50 is established and vehicle 10 and vehicle 50 are set to surveillance mode.

[0062] Furthermore, A22 illustrates a situation where a suspicious person T is identified from the photographic image captured by camera 13, or where the shaking of vehicle 10 is detected by an acceleration sensor or similar device when the suspicious person T attempts to open the door of vehicle 10, and an anomaly is identified by the first anomaly detection unit 32. In A22, the first notification control unit 33 executes a first notification based on horn 16 and lights 17. Furthermore, as described later, a second notification based on horn 56 and lights 57 is also executed in vehicle 50.

[0063] Return to Figure 2 In the flowchart, in step S8, when the door of the first vehicle 10 is unlocked, the first monitoring mode setting unit 31 causes the process to proceed to step S9. In step S9, the first monitoring mode setting unit 31 sends a first monitoring mode deactivation message to the second vehicle 50. Thus, as described later, the monitoring mode of the second vehicle 50 is deactivated. In the next step S10, the first monitoring mode setting unit 31 deactivates the monitoring mode of the first vehicle 10.

[0064] [2-2. Monitoring Processing in Vehicle 2]

[0065] Next, according to Figure 3 The flowchart shown illustrates the processing performed by the second monitoring mode setting unit 71 on the side of the second vehicle 50. Figure 3 In step S30, when the second monitoring mode setting unit 71 receives a response request signal from the first vehicle 10, the processing proceeds to step S31.

[0066] In step S31, the second monitoring mode setting unit 71 sends a response message to the first vehicle 10. In the next step S32, when the second monitoring mode setting unit 71 receives a pairing request message from the first vehicle 10 (when a pairing request exists from the first vehicle 10), the process proceeds to step S33. Conversely, if no pairing request is received from the first vehicle 10 (when no pairing request exists from the first vehicle 10), the second monitoring mode setting unit 71 proceeds to step S39, in which case the processing on the second vehicle 50 side ends.

[0067] In the next step S33, the second monitoring mode setting unit 71 performs pairing of the first vehicle 10 and the second vehicle 50. Thus, as referred to... Figure 5As explained above, the vehicle-unique code "98765" of the first vehicle 10 is written in the second memory 82. In the next step S34, the second monitoring mode setting section 71 causes the process to proceed to step S35 when the monitoring mode setting information is received from the first vehicle 10. In step S35, the second monitoring mode setting section 71 sets the second vehicle 50 to the monitoring mode.

[0068] Through the process cycles of the next step S36 and step S37, the second monitoring mode setting section 71 executes the second abnormality recognition process based on the second abnormality generation recognition section 72 and the second notification control section 73 in step S36 until the monitoring mode release information transmitted from the first vehicle 10 is received in step S37.

[0069] The second abnormality generation recognition section 72 recognizes the generation of the abnormality (theft, damage to the vehicle, etc.) of the first vehicle 10 when at least any one of the following (2-1) to (2-4) of the determination conditions is satisfied.

[0070] (2-1) The wireless communication between the first communication section 11 and the second communication section 51 is cut off.

[0071] (2-2) The electric wave strength (measured based on RSSI, etc.) of the wireless communication between the first communication section 11 and the second communication section 51 becomes the prescribed strength or less.

[0072] (2-3) The distance between the first vehicle 10 and the second vehicle 50 becomes the prescribed distance or less. The second abnormality generation recognition section 72 calculates the distance between the first vehicle 10 and the second vehicle 50 based on the current position of the second vehicle 50 detected by the GNSS sensor 55 and the information of the current position of the first vehicle 10 detected by the GNSS sensor 15 and transmitted from the first vehicle 10. Alternatively, the second abnormality generation recognition section 72 can recognize the distance between the first vehicle 10 and the second vehicle 50 based on the detected position information of the first vehicle 10 detected by the sonar 54 and the photographic image of the first vehicle 10 captured by the camera 53.

[0073] (2-4) The abnormality detection information is received from the first vehicle 10.

[0074] The second notification control section 73 causes the horn 56 or the lamp fixture 57 to operate when the generation of the abnormality of the first vehicle 10 is recognized by the second abnormality generation recognition section 72, thereby notifying the surroundings of the second vehicle 50. In this case, the notification method of the horn 56 and the lamp fixture 57 can also be changed according to the kind of the abnormality generated in the first vehicle 10. Thus, as referred to in the above embodiment, the notification method of the horn 56 and the lamp fixture 57 can be changed according to the kind of the abnormality generated in the first vehicle 10. Figure 6 、 Figure 7As explained above, it is possible to notify the surroundings that an abnormality has occurred in the first vehicle 10 by the notification of both the first vehicle 10 and the second vehicle 50.

[0075] [3. Other Embodiments]

[0076] In the above-described embodiments, the first vehicle 10 is exemplified as the first device and the first moving body of the present application, and the second vehicle 50 is exemplified as the second device and the second moving body of the present application. As other embodiments, it is sufficient that the first moving body and the second moving body are in a state where they can perform close-range wireless communication, and they can be moving bodies other than vehicles such as flying bodies and ships.

[0077] Further, the first device of the present application can also be a device such as a safe or a notebook computer that does not have a moving function and is moved by being carried by a user. The second device can also not be a moving body. For example, Figure 8 The case where the second device is a smart speaker 110 placed in the house 100 is shown. In the case of this configuration, when an abnormality of the first vehicle 10 is recognized, notification is performed by outputting a sound from the light 111 or the speaker 112 of the smart speaker 110, and it is possible to notify the user U in the house 100 that an abnormality of the first vehicle 10 has occurred. Further, the second device can also be a portable terminal 120 (a smartphone, a portable telephone, a tablet terminal, or the like), and in this case, it is also possible to notify the occurrence of an abnormality of the first vehicle 10 by the display or the sound output of the speaker of the portable terminal 120.

[0078] In the above-described embodiments, in Figure 2 In step S2 of the above-described configuration, the first monitoring mode setting section 31 searches for other vehicles parked in the vicinity of the first vehicle 10 and sets the second vehicle 50. As other embodiments, the second vehicle 50 can be set as a fixed vehicle that has been selected in advance. In this case, the second vehicle 50 is, for example, another vehicle that uses the same parking lot as the first vehicle 10, another vehicle that is stored in the same place as the first vehicle 10 in a vehicle sales shop or the like, or the like. In the case where the second vehicle 50 is set as a fixed vehicle, the vehicle unique code of the second vehicle 50 is recorded in advance in the first slot 42 of the first vehicle 10, and the vehicle unique code of the first vehicle 10 is recorded in advance in the second slot 82 of the second vehicle 50.

[0079] In the above-described embodiments, the first vehicle 10 is provided with the first abnormality occurrence recognition section 32 and the first notification control section 33, and when an abnormality of the first vehicle 10 occurs, notification is performed in both the first vehicle 10 and the second vehicle 50. As other embodiments, the first abnormality occurrence recognition section 32 and the first notification control section 33 can be omitted, and only the recognition and notification of the occurrence of an abnormality of the first vehicle 10 can be performed on the second vehicle 50 side.

[0080] In the above-described embodiment, in Figure 2 In step S3, the first monitoring mode setting section 31 can select, as the second vehicle 50, another vehicle that satisfies the following condition 1 or condition 2, when the response information is received from a plurality of other vehicles.

[0081] Condition 1…another vehicle whose elapsed time from the time point of end of use is the shortest. The first monitoring mode setting section 31 identifies the time point of end of use of another vehicle from the use information of another vehicle transmitted from another vehicle.

[0082] Condition 2…another vehicle whose next use start timing is presumed to be later than the next use start timing of the first vehicle 10. In the case where there is no other vehicle that coincides, another vehicle whose next use start timing is presumed to be closest to the next use start timing of the first vehicle 10. The first monitoring mode setting section 31 predicts the next use start timing of the first vehicle 10, for example, from the schedule information of the user of the first vehicle 10, and predicts the next use start timing of another vehicle from the schedule information of the user of another vehicle.

[0083] In the above-described embodiment, in the case where the first vehicle 10 and the second vehicle 50 are set to the monitoring mode, when the second vehicle 50 moves, the first monitoring mode setting section 31 cancels the monitoring mode with the second vehicle 50 that has moved, and sets the monitoring mode to another vehicle that can perform wireless communication through the first communication section 11 as a new second vehicle 50.
