A vehicle control apparatus according to an embodiment of the present invention comprises: a sensor unit detecting the speed of a vehicle in operation to output the detected speed and detecting the curvature of a road on which the vehicle is in operation to output the curvature of the road; and a control unit acquiring a first safety assurance distance corresponding to the detected speed and acquiring a second safety assurance distance by reflecting the curvature of the road to the first safety assurance distance to calculate road weighted curvature based on the curvature of the road when the curvature of the road is not less than reference weighted curvature for determining severe curvature, and acquiring a third safety assurance distance by reflecting the road weighted curvature to the first safety assurance distance such that the vehicle is controlled on the basis of one among the first safety assurance distance, the second safety assurance distance, and the third safety assurance distance according to the curvature of the road. Therefore, the present invention can reduce vehicle accidents on a curved road.
본 발명의 일 실시 예에 따른 차량 제어 장치는, 주행중인 차량의 속도를 검출하여 검출 속도를 출력하고, 상기 차량이 주행중인 도로의 곡선 정도를 검출하여 도로 곡선도를 출력하는 센서부; 상기 검출 속도에 대응되는 제1 안전보장 거리를 획득하고, 상기 제1 안전보장 거리에 상기 도로 곡선도를 반영하여 제2 안전보장 거리를 획득하여, 상기 도로 곡선도가 심한 곡선 정도를 판별하기 위한 기준 가중 곡선도 이상이면 상기 도로 곡선도에 기초해 도로 가중 곡선도를 산출하고, 상기 제1 안전보장 거리에 상기 도로 가중 곡선도를 반영하여 제3 안전보장 거리를 획득하여, 상기 도로의 곡선 정도에 따라 상기 제1 안전보장 거리, 상기 제2 안전보장 거리, 및 제3 안전보장 거리중 하나에 기초하여 차량 제어를 수행하는 제어부; 를 포함한다.
