Abstract

본 발명은 운전자가 차선변경시에 옆 차선의 후방차량과의 차간거리 및 후방차량과의 상대속도에 따라 안전여부를 진단하여 경고하도록 한 자동차의 차선변경 안전여부 경고장치에 관한 것이다.The present invention relates to a lane change safety warning device for a vehicle such that a driver diagnoses and warns of safety according to a distance between a rear vehicle of a side lane and a relative speed of a rear vehicle at the time of a lane change.

본 발명에 따르면, 운전석에 마련된 방향지시등스위치와; 상기 방향지시등스위치의 조작에 따라 선택적으로 좌우 옆 차선을 진행해오는 후방차량으로 초음파를 송수신하는 복수의 초음파센서와; 상기 복수의 초음파센서의 신호에 의해 차간거리를 판별하는 차간거리판별부와; 상기 차간거리판별부에서 판별된 차간거리의 단위시간당 변화량을 분석하여 후방차량과의 상대속도를 판별하는 상대 속도판별부와; 상기 속도판별 부, 상기 차간거리판별부 및 주행속도를 감지하는 차속센서의 신호를 분석 처리하여 출력하기 위한 콘트롤러와; 상기 콘트롤러의 출력 신호에 따라 경고음 또는 경고광을 발하는 경고수단로 구성된 것을 특징으로 하는 차선변경 안전여부 경고장치가 제공된다.According to the present invention, the turn signal switch provided in the driver's seat; A plurality of ultrasonic sensors for transmitting and receiving ultrasonic waves to a rear vehicle selectively traveling left and right lanes according to the operation of the turn indicator switch; An inter-vehicle distance discrimination unit for determining an inter-vehicle distance based on signals of the plurality of ultrasonic sensors; A relative speed discriminating unit for analyzing a change amount per unit time of the inter-vehicle distance determined by the inter-vehicle distance determining unit to determine a relative speed with the rear vehicle; A controller for analyzing and outputting signals of the vehicle speed sensor for sensing the speed discrimination unit, the inter-vehicle distance discrimination unit, and the traveling speed; Lane change safety warning device is provided, characterized in that consisting of a warning means for emitting a warning sound or warning light in accordance with the output signal of the controller.
