본 발명은 차선 옵셋값과 차선 헤딩각도를 이용하여 차선 모델을 생성하고 차선 모델을 이용하여 차량의 차선 유지를 보조하는 시스템을 제공한다. 더욱 상세하게 본 발명은, 도로에 대한 영상을 획득하는 카메라, 영상을 분석하여 차선을 감지하고 감지된 차선으로부터 차선 옵셋값을 계산하고 저장하는 영상 분석부, 전방 차량의 위치를 감지하는 레이더, 차량과 전방 차량이 이루는 전방 차량 헤딩각도를 계산하는 전방 차량 분석부 및 차선 가림이 발생할 때, 전방 차량 헤딩각도를 차선 헤딩각도로 적용하여 차선 모델을 생성하는 제어부를 포함하는 차선 유지 보조 시스템을 제공한다.

    Disclosed is a system that creates a lane model using a lane offset value and a lane heading angle and assists a vehicle in keeping its lane by using the lane model. More specifically, the system may include: a camera that obtains an image of the road; an image analyzing unit that detects lane markings by analyzing the image and calculates and stores the lane offset value from the detected lane markings; a radar that detects the position of the preceding vehicle; a preceding vehicle analyzing unit that calculates a preceding vehicle heading angle between the vehicle and the preceding vehicle; and a controller that, if the lane markings are blocked, applies the preceding vehicle heading angle to the lane heading angle to thereby create the lane model.
