Abstract

본 발명은 자동차의 사이드 미러를 통하여 볼 수 없는 사각지대에 위험물이 존재하는가를 감지하여 차선변경시 위험여부를 운전자에게 인식시킬 수 있도록 하는 자동차 사각지대의 위험감지 장치에 관한 것으로 사각지대의 위험물을 제대로 인식하지 못해 차선 변경시 사고가 발생되는 것을 방지하는 것이다.The present invention relates to a dangerous detection device of a blind spot for the blind spot to detect whether the dangerous goods exist in the blind spot that cannot be seen through the side mirror of the vehicle to recognize the danger to the driver when changing lanes. It is to prevent accidents when changing lanes because it is not properly recognized.

이를 위하여 본 발명은 자동차의 사각지대에 놓인 위험물을 감지하는 센서 수단과, 센서 수단에서 감지된 신호를 이용하여 거리를 계산하는 차간거리 계산 수단과, 계산된 거리와 자동차 속도를 받아 램에 기억된 차선 변경시 소요되는 거리 및 시간을 비교하여 차선변경 가능한가를 판단하는 비교수단과, 비교수단의 비교출력을 운전자에게 인식시키는 출력수단을 구비시킴으로써 이루어진다.To this end, the present invention is a sensor means for detecting a dangerous object placed in the blind spot of the vehicle, the vehicle distance calculation means for calculating the distance by using the signal detected by the sensor means, the calculated distance and the vehicle speed is stored in the RAM Comparing means for determining whether the lane can be changed by comparing the distance and time required for the lane change, and the output means for recognizing the comparison output of the comparison means to the driver.
