As shown in the drawings, the drones 100 according to the present invention are mounted on a vehicle and can be configured to receive a batch signal when a vehicle accident occurs, and to perform an alarm from the warning point w backward. Also, it can be controlled so as to receive the return signal generated when the rearrangement of the accident scene is completed and the vehicle can proceed and return to the home position.

The batch signal can be configured to be generated in various ways. The vehicle may generate a bass signal from the vehicle itself or may be generated by a user's selection. There is a possibility that the driver may not be injured in the event of a minor accident such as a light contact accident even in the event of a vehicle accident and in case of a major accident, the user may lose consciousness and forget the operation of the drone 100 . Therefore, the arrangement signal of the drone 100 can be generated by a user through a batch signal input unit (not shown) separately provided in the vehicle. And may also be configured to automatically generate a deployment signal in the vehicle when there is a high likelihood of severe damage to the vehicle, such as the operation of an airbag.

On the other hand, a message indicating that rearrangement of the drones 100 is possible can be informed to the user in order to recognize that the user can arrange the drones 100 before a batch signal is generated, . Therefore, even if the user forgets the user, it is possible to prompt the user whether or not the drones 100 are disposed. In the case where the arrangement of the drones 100 is not required, the drones 100 may not be disposed have.

When a batch signal is received, the drones 100 depart from the vehicle and start flying.

Therefore, the vehicle can be controlled to move to the warning point w spaced by a predetermined distance in the direction opposite to the traveling direction of the vehicle and to stop the vehicle on the accident lane.

At this time, the controller 170 calculates a predetermined distance from the accident point (a) to the warning point (w), and may be calculated by reflecting at least one of the limit speed, day / night, visibility and road surface state of the road. And a predetermined distance may be calculated with a distance of 100 m, which is a distance between the basic vehicles, as a minimum distance. For example, when the speed limit of the road is 110 km / h, the stop distance, which is the distance until the vehicle stops, may be longer than when the speed limit is 100 km / h. Can be calculated longer. Further, in the case of the nighttime, since the field of view is narrower than the daytime and can not be perceived well, the predetermined distance can be calculated longer. Further, when the visibility is short, the predetermined distance can be calculated to be longer, such as a mist-like edge, and when the state of the road surface slips following the rain, the predetermined distance d is calculated to be longer can do. Such a calculation of the predetermined distance d of the controller 170 is intended to prevent the occurrence of additional accidents by allowing the driver of the following vehicle to recognize the accident and to ensure a sufficient distance to avoid the accident.

Meanwhile, the control unit 170 may control the angle of the drones 100 such that the light emitting unit 161 faces rearward while the drones 100 are stationary at the warning point w. The light emitting unit 161 may be fixedly mounted on the body 110. When the light emitting unit 161 is configured to be recognizable in one direction, (170) controls the driving unit (120).

Since the speaker 163 can be installed facing the same direction as the above-described light emitting unit 161, if the angle of the drones 100 is controlled so that the light emitting unit 161 looks back, So that a warning sound can be generated. Therefore, the user can perceive the warning visually.

On the other hand, the return signal can be generated by the user operating the input unit when the rearrangement of the accident scene is completed. Meanwhile, the police or the firefighter who arrange the accident scene may have a separate device capable of generating the return signal of the dron 100 so that the dron 100 can be returned when the return signal can not be generated from the vehicle.

As described above, the drone 100 according to the present invention is configured to move to a warning point w when an accident occurs, and perform warning on the following vehicle. However, if the drones 100 are too high, the user's perception may be low. If the drones 100 are too low, a collision between the vehicle and the drones 100 may occur even if the user's perception is high.

Therefore, the drone 100 can be controlled to fly at a height higher than the maximum height of the general vehicle.

The control unit 170 can recognize the vehicle entering the drones 100 from the rear through the camera 130 and analyze the obtained images or use the distance sensor 140 to determine whether the drones 100 are stopped It can be judged whether it is proceeding to the lane in which it is flying. At this time, the control unit 170 may analyze the image, and when the height of the vehicle is judged to be a risk of collision with the drones 100, an algorithm may be implemented to control the height of the drones 100 to be high so as to avoid the collision.
