Zusammenfassung:	The present invention relates to a trailer detecting apparatus and a control method thereof. The trailer detecting apparatus, as the apparatus detecting a trailer mounted on the rear of a host vehicle, comprises: an ultrasonic sensor which detects a distance to a rear obstacle of the host vehicle; a rear camera which shoots the rear of the host vehicle; a side camera which shoots the rear side of the host vehicle; a cluster provided in the host vehicle and displaying information to a driver; and a control unit processing ultrasonic data detected by the ultrasonic sensor and video data shooted by the rear camera and the side camera. The control unit detects the distance to the rear obstacle through the ultrasonic sensor, and determines a width of the rear obstacle from a grid line rear view video shooted by the rear camera. In addition, the control unit determines a length of the rear obstacle from a grid line side view video shooted by the side camera, and determines whether the trailer is mounted on the host vehicle based on the distance to the rear obstacle and the width and the length of the rear obstacle. An objective of the present invention is to provide the trailer detecting apparatus for more effectively detecting existence of the trailer, and the control method thereof. 트레일러 검출 장치는 호스트 차량의 후방에 장착된 트레일러를 검출하는 장치에 있어서, 호스트 차량의 후방 장애물과의 거리를 검출하는 초음파 센서와, 호스트 차량의 후방을 촬영하는 후방 카메라와, 호스트 차량의 후측방을 촬영하는 사이드 카메라와, 호스트 차량에 마련되어 운전자에게 정보를 표시하는 클러스터 및 초음파 센서에 의해 검출된 초음파 데이터와 상기 후방 카메라 및 사이드 카메라에 의해 촬영된 영상 데이터를 처리하는 제어부를 포함하고, 제어부는 초음파 센서를 통해 후방 장애물과의 거리를 검출하고, 후방 카메라에 의해 촬영된 격자선 후방 뷰 영상으로부터 후방 장애물의 너비를 판단하고, 사이드 카메라에 의해 촬영된 격자선 사이드 뷰 영상으로부터 후방 장애물의 길이를 판단하고, 후방 장애물과의 거리, 후방 장애물의 너비 및 길이를 근거로 하여 호스트 차량에 트레일러의 장착을 판단한다.
