본 발명은 자차량 후면에 설치되어 양측후방을 감시하는 하나 이상의 레이더센서와, 자차량 후면에 설치되어 양측후방을 감시하는 하나 이상의 초음파센서를 포함하는 감지센서를 이용하여 양측후방에 위치하는 타차량을 감지하는 감지부와; 감지된 위치에 기초하여 타차량의 이동방향을 판단하며, 자차량을 기준으로 횡방향을 포함하는 일방향으로 이동하는 타차량을 타겟타차량으로 선정하고, 타겟타차량의 주행궤적을 추적하여 자차량에 접근하는지 또는 멀어지는지 판단하는 판단부; 및 타겟타차량이 접근하는 것으로 판단되면 레이더센서의 출력값에 의한 타차량의 트랙(Track)정보와 초음파센서의 출력값에 의한 타차량의 거리정보를 퓨전하여 퓨전타겟타차량을 선정하고, 퓨전타겟타차량과의 충돌시간을 산출하여 충돌시간이 미리 설정된 임계시간 이내이면 경고 표시장치, 경고음 출력장치 또는 제동장치가 동작하도록 제어하는 제어부를 포함하는 충돌방지장치에 관한 것이다.

    Disclosed is an apparatus for preventing a collision. The apparatus includes: a detection unit configured to detect another vehicle located at a rear side of both lateral sides through a detection sensor including one or more radar sensors disposed at a rear side of a driver's vehicle to monitor the rear side of both lateral sides and one or more ultrasonic sensors disposed at the rear side of the driver's vehicle to monitor the rear side of both lateral sides; a determination unit configured to determine a movement direction of the other vehicle based on the location, select the other vehicle that moves in one direction including a transverse direction from the driver's vehicle as a target vehicle, and determine whether the target vehicle approaches or moves away from the driver's vehicle by tracking a driving trace of the target vehicle; and a controller configured to, when it is determined that the target vehicle approaches the driver's vehicle, select a fusion target vehicle based on track information of the other vehicle by output values of the radar sensors and distance information of the other vehicle by output values of the ultrasonic sensors, calculate a time of collision with the fusion target vehicle and, when the collision time is within a preset threshold time, make a control to operate one or more of a warning display device, an alarm output device, and a braking system.
