Abstract

본 발명은 거리 측정 센서를 이용하여 앞, 뒤차 또는 장애물과의 거리를 측정하므로 일정거리 이하가 되면 자동적으로 경고음을 발생하거나 경고음 발생과 동시에 엘이디로 표시하여 줄 수 있는 자동차의 경고음 발생 장치에 관한 것으로, 앞차와의 거릴를 측정하고 이를 증폭 및 필터링하는 거리 검출수단, 자동차의 현재 속도를 검출하는 속도 검출부(5), 거리 검출수단과 속도 검출부(5)의 출력을 비교하여 하이 또는 로우 레벨을 출력하도록 제어하는 마이컴(13), 마이컴(13)의 제어에 따라 경고음을 발생시키거나 차단시키는 경고음 제어수단을 포함하여 이루어진다.The present invention relates to a vehicle warning sound generating device that can automatically generate a warning sound or an LED at the same time as a warning sound when a distance is less than a certain distance by using a distance measuring sensor to measure the distance to the front, rear or obstacle. And comparing the outputs of the distance detecting means for detecting the current speed of the vehicle, the speed detecting part 5 for detecting the current speed of the vehicle, the distance detecting means and the speed detecting part 5, and outputting a high or low level. Microcomputer 13 to control, it comprises a warning sound control means for generating or blocking the warning sound in accordance with the control of the microcomputer (13).
