본 발명은 차량의 후방 감지기를 작동할 경우 차량 후방의 트레일러를 감지하는 방법과 시스템에 관한 것으로, 특히 차량 후방 감지기에서 장착된 후방 트레일러를 인식하도록 함으로써, 차량의 후방에 트레일러 등을 장착할 경우에 후방 감지기에서 트레일러를 장애물로 감지하여 작동하게 되는 상황을 방지할 수 있을 뿐만 아니라, 차량 후방 감지 시스템의 사용상 편의성을 향상시키도록 한 것이다. 일 반적으로 차량에는 운전자의 안전사고 예방을 위하여 각종의 안전과 편의를 위한 서비스 장치가 설치되어 있다. 이러한 차량 장치 중에 후방 감지기는 후방 장애물과의 거리를 음성이나 문자 등으로 안내하도록 하여, 후진하는 차량의 운전자가 용이하게 후방 장애물과의 거리를 인식할 수 있도록 하고 있다. 상기한 차량의 후방 감지 시스템은, 차량 운전자가 별도의 표시 수단을 통해 거리를 인식할 필요가 없으므로 사고의 위험성을 줄여 주도록 하여, 최근에 차량에 설치를 많이 하는 추세이다. 그러나 상기한 종래의 차량 후방감지 시스템은, 차량의 후방에 트레일러 등을 장착하게 될 경우에, 후방 감지기에서 장착된 트레일러를 차량 후방의 장애물로 인식하여 작동하게 되어, 오히려 후방 감지기의 기능을 수행하지 못하고 불편한 문제점이 발생하였다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and system for detecting a trailer on the rear of a vehicle when a rear sensor of a vehicle is operated. In particular, when a rear trailer mounted on a vehicle rear sensor is recognized, It is possible to prevent the situation where the rear detector detects the trailer as an obstacle and to operate the vehicle, as well as to improve the usability of the vehicle rear detection system. In general, vehicles are equipped with various safety and convenience service devices to prevent driver safety accidents. Among such vehicle devices, the rear sensor guides the distance to the rear obstacle by voice or characters so that the driver of the backward vehicle can easily recognize the distance to the rear obstacle. The rear detection system of the vehicle has a tendency to reduce the risk of an accident because the driver does not need to recognize the distance through a separate display means, and has recently installed much in the vehicle. However, when the trailer or the like is mounted on the rear of the vehicle, the conventional rear vehicle detection system recognizes the trailer mounted on the rear sensor as an obstacle behind the vehicle, and thus operates as a rear sensor And the problem was inconvenient.
따라서 본 발명은 차량 후방 감지기에서 장착된 후방 트레일러를 인식하도록 함으로써, 차량의 후방에 트레일러 등을 장착할 경우에 후방 감지기에서 트레일러를 차량 후방의 장애물로 감지하여 작동하는 문제점을 해소하도록 하고, 차량 후방 의 트레일러를 인식하여, 차량의 후방감지 시스템의 사용상 편의성을 향상시키도록 하는데 그 목적이 있는 것이다.Therefore, according to the present invention, when a trailer or the like is mounted on the rear of a vehicle, it is possible to solve the problem of detecting the trailer as an obstacle in the rear of the vehicle by operating the rear sensor, And it is an object of the present invention to improve the convenience of use of the rear detection system of a vehicle.

N2 단계는 트레일러 인식 스위치가 ON 위치에 있는가를 판단하도록 한다.In step N2, it is determined whether the trailer recognition switch is in the ON position.
N3 단계는 상기 N2 단계에서 트레일러 인식 스위치가 ON 위치가 확인되면, 트레일러의 위치 및 형상을 메모리에 기억하도록 한다.In step N3, when the ON position of the trailer recognition switch is confirmed in step N2, the position and shape of the trailer are stored in the memory.
N4 단계는 상기 N2 단계에서 트레일러 인식 스위치가 OFF 위치가 확인되면, 차량 후방 물체의 감지 기능을 수행하도록 한다.In step N4, when the OFF position of the trailer recognition switch is confirmed in step N2, a detection function of the rear vehicle object is performed.
N5 단계는 차량 후방의 물체의 존재 여부를 확인하도록 한다.In step N5, the presence of an object behind the vehicle is confirmed.
N6 단계는 차량 후방의 물체의 존재가 확인되면 경보음을 발생하도록 한다.In step N6, an alarm sound is generated when the presence of an object behind the vehicle is confirmed.
