In addition, for example, in an abnormal vehicle condition where a suspicious individual causes harm to the vehicle, the unmanned air vehicle takes off from the vehicle, which has the same effect as giving a warning to the suspicious individual. Can be suppressed.

Further, it is preferable that at least the warning unit is provided around the vehicle, and the control unit may further issue a warning by the warning unit when the abnormal condition detection unit detects the abnormal condition.
Thereby, in an abnormal state of the vehicle in which the suspicious individual damages the vehicle, a warning is given to the suspicious individual, thereby further suppressing the suspicious individual from damaging the vehicle.

Further, preferably, at least a contact unit for contacting the portable device of the owner of the vehicle is provided, and the control unit is further provided by the contact unit when the abnormal condition is detected by the abnormal condition detection unit. The owner may be notified of the abnormal condition.
As a result, the owner located far from the vehicle can be notified of the abnormal state, and the owner can return to the vehicle and deal with it.

Further, preferably, the contact unit may transmit an image taken by the camera to the portable device when notifying the owner of an abnormal state.
With this, when an abnormal condition is reported to the owner who is away from the vehicle, the image around the vehicle is sent to the mobile device, so the owner can confirm the contents of the abnormal condition on the spot. It can be carried out.

Further, preferably, the abnormal state includes a case where the vehicle is in a parked state, when the vehicle is damaged, and when a suspicious object is detected around the vehicle, and when the vehicle is in a traveling state, It is preferable to include the case where a moving suspicious object that has come into contact is detected.
As a result, when the vehicle is parked, a suspicious object that damages the vehicle or a suspicious object around the vehicle can be photographed by the camera. Further, when the vehicle is in a traveling state, a moving suspicious object that comes into contact with the vehicle can be photographed by the camera.

Further, preferably, the control unit causes the unmanned air vehicle to trace the suspicious object shown in the image captured by the camera when the abnormal state is detected by the abnormal state detection unit.
As a result, since the unmanned air vehicle tracks the suspicious object, it is possible to secure a long shooting time for the suspicious object and to confirm the direction in which the suspicious object escaped.

Further, preferably, the control unit raises the unmanned aerial vehicle when the suspicious object moves outward from the imaging range of the camera when the abnormal state is detected by the abnormal state detection unit. It is better to move to.
As a result, the unmanned air vehicle moves upward to increase the shooting range of the camera, so that even if the suspicious object moves away from the vehicle, the shooting range can be expanded and the shooting time of the suspicious object can be secured for a long time. You can check the direction in which the object escaped.

Further, preferably, the control unit, when the suspicious object is separated from the vehicle by a predetermined distance or more, or when the charging rate of the battery of the unmanned aerial vehicle is equal to or less than a predetermined value, the unmanned aerial vehicle. May be returned to the vehicle for landing.
Thus, when a suspicious object is tracked by an unmanned aerial vehicle, the unmanned aerial vehicle can be returned to the vehicle before the flight time is exceeded, and the unmanned aerial vehicle can be collected.

According to the vehicle security device of the present invention, when a suspicious object such as a suspicious person or a suspicious vehicle detects an abnormal state that damages the vehicle, the suspicious object is photographed by the camera of the unmanned air vehicle that has taken off from the vehicle. Therefore, it is possible to reduce the image leakage of the suspicious object, easily identify the suspicious object, and improve the security capability of the vehicle.

FIG. 3 is a flowchart showing a vehicle security control procedure executed in the vehicle security device of the first embodiment.

This control is executed jointly by the vehicle-mounted device 300 and the drone 100, and is executed, for example, when the vehicle is parked.
As shown in FIG. 3, first, in step S10, the abnormal state detection unit 314 determines whether or not an abnormal state is detected. If an abnormal state is detected, the process proceeds to step S20. If no abnormal state is detected, step S10 is repeated.

In step S20, it is determined whether the drone 100 needs to take off. Regarding whether or not the drone 100 needs to take off, it is determined that the vehicle 200 is in an abnormal state in which the vehicle 200 is damaged or impacted from the vibration, the abnormal noise, or the like detected by the abnormal state detection unit 314. If so, it is determined that takeoff is necessary. In addition, when the owner of the vehicle 200 is in the vehicle 200 or near the vehicle 200, it may be determined that the takeoff of the drone 100 is unnecessary. The position of the owner of vehicle 200 may be estimated from the position of the remote key of vehicle 200 or the like. If the drone 100 needs to take off, the process proceeds to step S30. If the drone 100 does not need to take off, the process returns to step S10.

In step S30, the drone 100 is taken off from the vehicle 200. The drone 100 may be controlled to be located a few meters above the vehicle. Then, the process proceeds to step S40.
In step S40, the camera 101 of the drone 100 automatically photographs the vehicle 200 and the surroundings of the vehicle 200. The image captured by the camera 101 is recorded in the recording unit 306 of the vehicle-mounted device 300 via the video data wireless transmission unit 105, the video data wireless reception unit 302, and the like. Then, the process proceeds to step S50.

In step S50, the warning sound or warning sound is output from the warning sound output unit 110 included in the drone 100. Note that a warning sound or a warning sound may be output from the speaker or the like mounted on the vehicle 200 toward the outside of the vehicle. Then, the process proceeds to step S60.
In step S60, the owner contact unit 310 notifies the portable device of the owner of the vehicle 200 that the vehicle 200 is in an abnormal state. In addition, when notifying that the vehicle 200 is in an abnormal state, it is preferable to sequentially transmit the images around the vehicle taken by the camera 101 to the portable device. Furthermore, you may contact the security company etc. with the owner of the vehicle 200. Note that the communication to the mobile device in this step may be repeated every predetermined time or may be performed only once until the abnormal state response control in step S80 described later is completed. Then, the process proceeds to step S70.

Note that the automatic shooting in step S40, the warning output in step S50, and the contact to the owner in step S60 may be sequentially executed without any time after the drone 100 takes off, or may be executed for several seconds at each step. It may be executed after some time. In the case of executing the operation after a lapse of time, when the abnormal image detection is canceled immediately after starting the automatic photographing in step S40, the control of step S50 and step S60 may be skipped and the process may proceed to step S80.

In step S70, it is determined whether the abnormal state detection by the abnormal state detection unit 314 has been canceled. If the abnormal state detection is canceled, the process proceeds to step S80. If the abnormal state detection is not canceled, the process returns to step S40.
In step S80, the abnormal state response control such as the automatic shooting in step S40 and the warning output in step S50 is ended. Then, the process proceeds to step S90.

In step S90, the drone 100 is automatically landed on the takeoff/landing port 401 of the vehicle 200, and the drone 100 is stored in the vehicle pedestal 400 of the vehicle 200. Regarding the automatic landing control of the drone, the flight control of the drone 100 is performed so that the position of the drone 100 detected by the first GPS sensor 102 and the position of the vehicle 200 detected by the second GPS sensor 313 match. Good. Alternatively, the drone 100 may be controlled to be guided to the takeoff/landing port 401 of the vehicle 200 based on the image of the camera 101 provided on the drone 100. Then, this routine is finished.

With the above control, the vehicle security device according to the first embodiment of the present invention detects an abnormal state when a suspicious object such as a suspicious person scratches or impacts the vehicle 200 when the vehicle is parked. In such a case, the drone 100 mounted on the vehicle 200 takes off and automatically photographs the vehicle 200 and the surroundings of the vehicle 200, so that a suspicious object can be photographed by the camera 101.

In particular, since the camera 101 of the drone 100 that has taken off above the vehicle captures the surroundings of the vehicle, it is possible to capture the entire periphery of the vehicle with one camera 101, and reduce the omission of capturing suspicious objects, particularly suspicious objects. It is possible to easily identify the person. Thereby, the security capability of vehicle 200 can be improved.
In addition, when the suspicious person is damaging the vehicle 200, the drone 100 can take off from the vehicle 200, thereby giving the same effect as giving a warning to the suspicious person. It is possible to prevent the person from continuing to damage the vehicle 200.

Further, when the abnormal state is detected, the warning sound output unit 110 of the drone 100 gives a warning, so that it is possible to further prevent a suspicious person from continuing to damage the vehicle 200.
Further, when the abnormal state is detected, the portable device of the owner of the vehicle 200 is notified of the abnormal state, so that the owner can immediately return to the vehicle 200 and deal with it.

Furthermore, when an abnormal condition is detected and the portable device of the owner of the vehicle 200 is notified of the abnormal condition, an image around the vehicle 200 taken by the camera 101 is transmitted to the portable device, so that a suspicious person can be confirmed. The owner can confirm the contents of the abnormal state on the spot.
Next, a vehicle security device according to a second embodiment of the present invention will be described with reference to FIG.
FIG. 4 is a flowchart showing a vehicle security control procedure executed in the vehicle security device according to the second embodiment of the present invention.

The vehicle security device according to the second embodiment of the present invention may be executed when the vehicle is running, for example, other than when the vehicle is parked.
The vehicle security device of the second embodiment has the same configuration as that of the first embodiment, but the content of the vehicle security control is partly different.
As shown in FIG. 4, in the vehicle security control according to the second embodiment, the process proceeds to step S100 after step S40 of the vehicle security control according to the first embodiment.

In step S100, the drone 100 traces a suspicious person such as a suspicious person or a suspicious vehicle that has come into contact with or abnormally approaches the vehicle 200. As a tracking method of the drone 100, when the suspicious object attempts to deviate from the image captured by the camera 101 from above, that is, when the suspicious object moves outward from the imaging range of the camera 101, The drone 100 is moved so that the suspicious object does not deviate. Here, when tracking a suspicious object, the altitude of the drone 100 may be increased first. Then, the process proceeds to step S110.

In step S110, it is determined whether or not the tracking condition has been canceled. The tracking condition is canceled when the suspicious object to be tracked is separated from the vehicle 200 by a predetermined distance or more, or when the owner receives an instruction to stop the tracking through the microphone 309 of the vehicle-mounted device 300 or the portable device. And The predetermined distance may be changed so that the predetermined distance is shortened as the charging rate of the battery 109 of the drone 100 decreases, for example. If the tracking condition is canceled, the process proceeds to step S120. If the tracking condition is not released, the process returns to step S40.

In step S120, the automatic shooting by the camera 101 of the drone 100 ends. Then, the process proceeds to step S90 in the vehicle security control of the first embodiment.
As described above, in the vehicle security device according to the second embodiment of the present invention, an abnormal state is detected when a suspicious person or a suspicious object such as a suspicious vehicle damages or impacts the vehicle 200. In this case, the drone 100 mounted on the vehicle 200 takes off and automatically captures the surroundings of the vehicle 200, so that a suspicious object can be captured by the camera 101 as in the first embodiment.

In the second embodiment, since the drone 100 tracks the suspicious object, it is possible to secure a long shooting time for the suspicious object and to confirm the escape direction of the suspicious object.
Further, as described above, by tracking with the drone 100, tracking the escaped suspicious object, and photographing for a long time, it is possible to secure a large amount of evidence material for identifying the suspicious object.
Further, when an abnormal state is detected while the vehicle 2 is running, such as when the vehicle 200 is hit and escaped, the drone 100 causes the fugitive vehicle to be tracked so that the fugitive vehicle is photographed for a long time. Therefore, it is possible to secure a large amount of evidence that identifies the escaped vehicle.

Further, when tracking a suspicious object that has damaged the vehicle 200, the shooting range of the camera 101 is expanded by first increasing the altitude of the drone 100, so that the suspicious object is less likely to deviate from the shooting range.
Also, when tracking a suspicious object that has caused damage to the vehicle 200, if the tracking conditions are canceled, tracking will be stopped and the drone will be returned to the vehicle 200 to automatically land, thus preventing unnecessary tracking. You can For example, when the suspicious object is separated from the vehicle 200 by a predetermined distance or more, the drone 100 can be automatically landed on the vehicle to prevent the drone 100 from being uncollectible.

The present invention is not limited to the above embodiment. For example, in the vehicle security control of the first embodiment, the warning output in step S50 and the contact to the owner in step S60 may be appropriately selected and performed. Further, in the vehicle security control of the second embodiment, the warning output of step S50 and the contact of the owner of step S60 may be performed together with the automatic shooting, as in the first embodiment.

Further, the vehicle security control of the first embodiment described above is executed when the vehicle is parked, but it may be executed when the vehicle is traveling as in the second embodiment.
