The present invention obtains driving information from an autonomous driving device of an autonomous vehicle driving on a front road to determine whether there is an accident situation on the front road, and notifies autonomous vehicles driving on a rear road of whether there is an accident situation. Therefore, the present invention can use the autonomous driving devices of gradually increasing autonomous vehicles, without the need to install a separate device, to transmit and receive information on an accident situation on a road between the autonomous vehicles. Additionally, the present invention can prepare for the condition of the front road by adjusting the safety distance between vehicles and reducing driving speed when an autonomous vehicle driving on the rear road enters the front road. In addition, the present invention can prevent collision accidents by preparing for shock waves generated when a leading autonomous vehicle suddenly slows down in congested areas and following autonomous vehicles sequentially apply brakes.

    본 발명은 전방도로를 주행하는 자율주행 차량의 자율주행장치로부터 주행정보를 획득하여 전방도로의 유고상황 여부를 판단하고 후방도로를 주행하는 자율주행 차량에 유고상황 여부를 알린다. 이로 인해, 별도의 장치를 설치할 필요 없이, 점차 증가되고 있는 자율주행 차량들의 자율주행장치를 이용하여 자율주행 차량들 간에 도로의 유고상황에 대한 정보를 주고받을 수 있다. 또한, 후방도로를 주행하는 자율주행 차량이 전방도로에 진입할 때, 차량 간 안전거리를 조정하고, 주행속도를 줄이는 등 전방도로의 상태에 대비할 수 있다. 또한, 지정체 구간에서 선행 자율주행 차량이 갑자기 속도를 줄여 후행 자율주행 차량이 연쇄적으로 브레이크를 밟으면서 발생하는 충격파에 대비하여 추돌사고를 예방할 수 있다.
