본 발명은, 차량의 전방에 주행중인 제1 전방차량 및 상기 제1 전방차량보다 전방에 주행중인 제2 전방차량 사이의 제1 충돌위험도를 산출하는 단계, 상기 제1 전방차량과의 제2 충돌위험도를 산출하는 단계, 상기 차량의 후방에서 접근 주행중인 후방차량과의 제3 충돌위험도를 산출하는 단계, 상기 제1 충돌위험도와 설정된 제1 기준충돌위험도를 기반으로 상기 제1, 2 전방차량 사이에 충돌 가능 여부를 판단하는 단계 및 상기 제1, 2 전방차량 사이에 충돌 가능으로 판단되면, 상기 제2, 3 충돌위험도에 따라 연쇄충돌경보시점 및 연쇄충돌제동시점을 가변시켜 경보발생 및 제동을 수행하는 단계를 포함하는 자동제동 시스템의 동작방법을 제공한다.
The present invention provides a method for operating an automatic brake system comprising: a step of calculating a first collision risk degree between a first preceding vehicle driven in front of a vehicle and a second preceding vehicle driven in front of the first preceding vehicle; a step of calculating a second collision risk degree with respect to the first preceding vehicle; a step of calculating a third collision risk degree with respect to a following vehicle driven to approach in rear of the corresponding vehicle; a step of determining whether a collision is possible between the first preceding vehicle and the second preceding vehicle based on the first collision risk degree and a first reference collision risk degree; and a step of generating an alarm and performing braking by changing a chain collision alarming time and a chain collision braking time depending on the second collision risk degree and the third collision risk degree when possibility of a collision between the first preceding vehicle and the second preceding vehicle is determined. According to the present invention, a chain collision accident can be prevented from occurring on a highway road where a vehicle is driven at a high speed.
