Disclosed is a method for preventing a collision of an autonomous vehicle, capable of preventing a collision by issuing an alarm when there is a risk of collision based on the probability of a collision with a counterpart vehicle while the autonomous vehicle is underway. The method of the present invention comprises the steps of: predicting, by a counterpart vehicle location predicting unit, a driving route of a counterpart vehicle, and predicting a subsequent location followed by the current location of the counterpart vehicle on the predicted driving route; recognizing, by the user vehicle′s location recognizing unit, its current location and the subsequent location of the autonomously driven user vehicle; calculating, by the relative distance calculating unit, the distance to and between subsequent locations of the counterpart vehicle and the user vehicle; calculating, by the control unit, a collision probability between the user vehicle and the counterpart vehicle by reflecting the distance of the subsequent locations between the counterpart vehicle and the user vehicle and one or more consideration factors to a pre-stored collision probability function; and issuing, by the control unit, a collision alarm through an alarm unit on the basis of the calculated collision probability.

    자율주행차량의 주행중에 상대차량과의 충돌 확률을 기반으로 충돌 위험성을 경고해 주어 충돌을 미연에 예방할 수 있도록 하는 자율주행차량을 위한 충돌 예방 방법을 제시한다. 제시된 방법은 상대차량 위치 예측부가, 상대차량의 주행경로를 예측하고 예측된 주행경로에서 상대차량의 현재 위치에 수반되는 후속 위치를 예측하는 단계; 자차 위치 파악부가, 자율주행중인 자차의 현재 위치 및 후속 위치를 파악하는 단계; 상대거리 계산부가, 상대차량과 자차간의 후속 위치에서의 거리를 계산하는 단계; 제어부가, 상기 상대차량과 자차간의 후속 위치에서의 거리 및 하나 이상의 감안요소를 기저장된 충돌 확률 함수에 반영하여 자차와 상대차량간의 충돌 확률을 계산하는 단계; 및 상기 제어부가, 계산된 충돌 확률에 근거하여 경고부를 통해 충돌 경고를 행하는 단계;를 포함한다.
