Disclosed is an obstacle warning apparatus for a vehicle, which has improved obstacle warning performance. The obstacle warning apparatus for a vehicle according to an embodiment of the present invention comprises: a first ultrasonic sensor disposed in a first position of a vehicle to detect an obstacle; a second ultrasonic sensor disposed in a second position of the vehicle; a warning area generation unit for generating a warning area by using an ellipse which is a set of points using the first position and the second position as focal points and having the constant sum of distances from the two focal points; a distance calculation unit for calculating the distance sum of a first distance value between the first ultrasonic sensor and the obstacle and a second distance value between the second ultrasonic sensor and the obstacle; a control unit for determining the warning area, in which the obstacle is positioned, according to the calculated distance sum; and a warning output unit for warning the obstacle according to the control of the control unit.

    차량용 장애물 경보장치가 개시된다. 본 발명의 일실시예에 따른 차량용 장애물 경보장치는 장애물을 검출하도록 차량의 제1 위치에 마련된 제1 초음파센서와, 차량의 제2 위치에 배치된 제2 초음파센서와, 제1 위치 및 제2 위치를 초점으로 갖고 두 초점에서 거리의 합이 일정한 점들의 집합인 타원을 이용하여 경보영역을 생성하는 경보영역생성부와, 제1 초음파센서와 장애물 간의 제1 거리값과 제2 초음파센서와 상기 장애물 간의 제2 거리값을 합한 거리합을 산출하는 거리산출부와, 산출된 거리합에 따라 장애물이 위치한 경보영역을 판단하는 제어부 및 제어부의 제어에 따라 장애물을 경보하는 경보출력부를 포함한다.
