The present invention relates to a lane change assistant system which reflects a situation mode of a vehicle. According to the present invention, an electronic device installed on the vehicle calculates risk factors (RF) in real time by using a current vehicle speed (v), distance (d) from a vehicle placed on a rear side of the lane to be measured by a sensor, and a lane change safety distance (d1(v)) in the vehicle speed which is pre-determined through a speed and safety distance table. The calculation allows a constant from among a plurality of situation mode values (S) to be multiplied. In addition, the present invention includes a step of matching the RF value of a result of the calculation and a plurality of set levels to discriminately execute a driver alarm within the vehicle in accordance with the level. The present invention aims to provide a method to quantitatively calculate various risk factors (RF), which may occur when a driver changes to another lane on a side, in real time while driving the vehicle and to discriminately express the RF for each ranking.

    본 발명은 차량의 상황모드를 반영한 차선 변경 보조 방법에 관한 것입니다. 본 발명의 방법은 차량에 설치되어 있는 전자장치가, 현재 차속(v)과, 센서에 의해 측정되는 변경 대상 차선의 뒤쪽에 위치하는 차량과의 거리(d)와, 속도 및 안전거리 테이블을 통해 미리 정해져 있는 값인 상기 차속에서의 차선변경 안전거리(d1(v))를 이용해서 위험 요소(Risk Factor: RF)를 실시간으로 연산합니다. 이런 연산에는 복수의 상황모드 값(S) 중에서 어느 한 상수가 곱해지도록 합니다. 또한, 연산 결과의 RF 값과 설정된 복수의 레벨을 매칭하여 그 레벨에 따라 차량 내 운전자 알람을 차별적으로 실행하는 단계를 포함합니다.
