The attitude control unit 340 corresponds to the third position detection unit, and the parking detection unit 144 corresponds to the parking detection unit.

  The vehicle position guidance system of this embodiment has such a configuration, and the operation thereof will be described next. For example, each operation is performed according to the following steps S1 to S7.

  (Step S1) During parking, the vehicle position is transmitted from the in-vehicle device 100 to the drone 300. Specifically, the vehicle position transmission unit 142 in the in-vehicle device 100 sets the vehicle position detected using the GPS device 110 to the drone 300 when the parking detection unit 144 detects that the vehicle is parked. Send. The vehicle position is received by the vehicle position receiving unit 320 in the drone 300 and is stored and held in a memory (not shown) or the like.

  (Step S2) The user U moves from place to place the desired action, and then returns to the parking lot P. At this point, the user U cannot accurately remember the position where he / she parked the vehicle, and the vehicle position guidance system of the present invention is used.

  (Step S <b> 3) The user U operates the operation unit 220 of the mobile terminal device 200, and a flight start instruction is sent from the mobile terminal device 200 to the drone 300. Specifically, the flight start instruction transmission unit 252 specifies the position (user position) of the mobile terminal device 200 using the GPS receiver 210 in response to the operation of the user U, and this user position. Is sent to the drone 300. This flight start instruction is received by the flight start instruction receiving unit 322 in the drone 300, and the user position is stored in a memory or the like.

  (Step S4) The drone 300 that has received the flight start instruction takes off from the mounting position of the vehicle G and automatically flies to the vicinity of the user U. Specifically, the flight control unit 330 reads out the vehicle position and the user position stored in the memory or the like, and performs drive control so that the drone 300 flies along the flight path from the vehicle position to the user position. Flight control (first flight control) for sending an instruction to the unit 342 is performed.

  (Step S <b> 5) After visually confirming the drone 300 flying, the user U operates the operation unit 220 of the mobile terminal device 200, and a return instruction to return the drone 300 to the vehicle position is sent from the mobile terminal device 200 to the drone 300. Sent. Thereby, the flight direction of the drone 300 is reversed and the flight toward the vehicle G is started. Specifically, the return instruction transmission unit 254 transmits a return instruction to the drone 300 in response to the operation of the user U. This return instruction is received by the return instruction receiving unit 324 in the drone 300. The flight control unit 330 performs flight control (second flight control) that sends an instruction to the drive control unit 342 so that the drone 300 flies along the flight path from the current position to the vehicle position.

  (Step S <b> 6) The user U follows the same direction so that the drone 300 flying toward the vehicle G is visually confirmed and not lost. The flying speed of the drone 300 at this time is set to be approximately the same as the speed of the user U (the general speed of the pedestrian), and the distance to the user U is a predetermined distance or more. It is controlled not to leave. For example, the user position receiving unit 326 receives the user position periodically transmitted from the user position transmitting unit 256 in the mobile terminal device 200 to the drone 300, and the position of the drone 300 and the user. When the distance to the position reaches a predetermined distance, it can be realized by controlling the drone 300 to perform hovering at the position for a predetermined time by the flight control unit 330.

  (Step S <b> 7) After reaching the vehicle G, the user U operates the mobile terminal device 200, and a flight end instruction is sent from the mobile terminal device 200 to the drone 300. Specifically, the flight end instruction transmission unit 258 transmits a flight end instruction to the drone 300 in response to the operation of the user U. This flight end instruction is received by the flight end instruction receiving unit 328 in the drone 300. Thereafter, the flight control unit 330 causes the drone 300 to land at a predetermined position of the vehicle G. Thus, a series of operations for guiding the user to the vehicle position is completed.

  Thus, in the vehicle position guidance system of the present embodiment, the user can easily grasp the vehicle position by visual observation by reciprocating the drone 300 between the vehicle position and the user position. This makes it possible to reliably guide the user to the vehicle position.

  In addition, the drone 300 acquires the vehicle position sent from the in-vehicle device 100 and the user position sent from the mobile terminal device 200 carried by the user, and based on these vehicle position and user position. By flying the drone 300, the user can be reliably guided to the vehicle position.

  In addition, by using the vehicle position as a position to be the user's guidance destination, when the vehicle is parked in a large parking lot or the like, the user can be reliably guided to the parking position.

  Further, by using the position of the mobile terminal device 200 carried by the user as the user position, it becomes easy to grasp the position of the user, and it is possible to reliably guide the user to the vehicle position.

  In addition, when a turn-back instruction for returning the flight of the drone 300 is sent from the mobile terminal device 200, the drone 300 performs flight control toward the vehicle, so that the drone is confirmed after the user confirms the existence of the drone 300. 300 can be turned back.

  In addition, a pedestrian does not lose sight of the drone 300 by performing hovering once or a plurality of times during the flight so that the distance between the drone 300 and the mobile terminal device 200 is not more than a predetermined distance. However, it is possible to reliably guide to the vehicle position.

  In addition, since the drone 300 itself performs flight control that reciprocates between the vehicle and the user, the system configuration can be simplified.

  Moreover, the parking detection part 144 which detects that the vehicle was parked is provided, and the vehicle position information (first position information) is transmitted to the flying object 300 when the vehicle is parked. The time position can be reliably sent to the flying object 300.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, the drone 300 is hovered so that the distance between the drone 300 and the mobile terminal device 200 is not more than a predetermined distance, but the drone 300 and the mobile terminal device 200 Hovering may be performed once or a plurality of times regardless of the distance between them. In this case, the operation of periodically transmitting the user position from the mobile terminal device 200 to the drone 300 may be omitted.

  In the above-described embodiment, when the return instruction is transmitted from the mobile terminal device 200 to the drone 300, the drone 300 reverses the flight direction. However, the drone 300 itself grasps the user position. Therefore, when the drone 300 approaches the vicinity of the user, the direction of flight may be reversed without waiting for a turn-back instruction. In this case, the operation of transmitting a return instruction from the mobile terminal device 200 to the drone 300 may be omitted.

  In the above-described embodiment, the drone 300 is reciprocated once between the vehicle and both, but may be reciprocated two or more times.

  In the above-described embodiment, the case where the drone 300 takes off from the vehicle position has been considered. However, the drone 300 is taken off from a specific position (for example, a private house or a specific facility) other than the vehicle position, and the users around the drone 300 take off. The present invention can also be applied to the case of guiding to the specific position.

  As described above, according to the present invention, the user can easily grasp the specific position visually by causing the flying object to reciprocate between the specific position and the portable terminal (carried by the user). This makes it possible to reliably guide the user to a specific position.
