The present invention relates to a collision preventing alarming device for a vehicle and, more specifically, to a collision preventing alarming device for a vehicle having an ultrasonic sensor to have a wider sensing area. To this end, the present invention provides the collision preventing alarming device for a vehicle, capable of calculating the distance between the user′s vehicle and a vehicle driving in the front side of the user′s vehicle by emitting a laser beam to the front side of a user′s vehicle, receiving reflected ultrasonic waves, and signal-processing the reflected ultrasonic waves and generating an alarm when possibilities of collision are determined by comparing the calculated distance between the vehicles and a stopping distance in accordance with a current driving speed of the user′s vehicle. The collision preventing alarming device is characterized by including: a reflector (44) reflecting the ultrasonic waves emitted to the front side of the user′s vehicle to the front side of the user′s vehicle; a reflector driving unit (45) repeatedly rotating the reflector (44) within a predetermined turning radius; a standard position sensor (46) sensing an initial driving position of the reflector (44) and limiting an area where the ultrasonic waves are emitted; and a control unit (20) controlling the reflector driving unit (45) in accordance with the sensed result of the standard position sensor (46) and continuously changing the emitting direction of the ultrasonic waves emitted to the front side of the user′s vehicle.
본 발명은 자동차의 충돌방지경보장치에 관한 것으로, 더욱 상세하게는 보다 넓은 감지영역을 갖도록 초음파센서를 구비한 자동차의 충돌방지경보장치에 관한 것이다. 이를 위하여 본 발명은 자차의 전방을 향하여 레이져빔을 발사하고, 반사초음파를 수신 및 신호처리하여 자차와 선행차량과의 찻간거리를 연산하고, 자차의 현재속도에 따른 정지거리를 상기 산출된 찻간거리와 비교하여 충돌가능성이 있다고 판단될 때 경보를 발하는 자동차의 충돌방지경보장치에 있어서, 자차의 전방을 향해 발사되는 초음파를 자차의 전방으로 반사시키는 반사경(44), 상기 반사경(44)을 소정의 회전반경내에서 반복적으로 회전구동시키는 반사경구동부(45), 상기 반사경(44)의 초기구동위치를 감지하여 초음파의 발사영역을 제한하는 기준위치센서(46), 상기 기준위치센서(46)의 감지결과에 따라 상기 반사경구동부(45)를 제어하여 자차 전방으로 발사되는 초음파의 발사방향을 연속적으로 가변시킬 수 있도록하는 제어부(20)를 구비한 것을 특징으로 한다.
