Abstract

본 발명은 자동차 타이어 공기압 저하 경보시스템에 관한 것으로, 자동차 앤티-록 브레이크 시스템(ABS)에서 각 휠의 회전속도를 검출하는 4개 휠 스피드센서와, 전자제어장치 내부에 설치되어 차량요y축 중력가속도를 검출하는 가속도 센서와, 이 가속도 센서의 측면중력가속도 값을 검출하여 미리 정해진 한계값 미만일 때 대각선 방향의 2개 휠 스피드센서에서 입력된 차륜속을 더하고 그 상대 대각성 방향으로 더한 차륜속과 비교하므로써 그 차이값이 설정치보다 크거나 작게 산출되고 이것이 일정시간 지속되면 이에 따라 출력단에서 소정레벨의 전압을 발생하는 전자제어장치와, 이 전자제어장치의 출력단에서 발생한 전압신호에 의해 구동되는 경보발생수단으로 이루어진다.The present invention relates to a vehicle tire air pressure drop warning system, four wheel speed sensor for detecting the rotational speed of each wheel in the car anti-lock brake system (ABS), and the vehicle yaw axis gravity installed inside the electronic control device Accelerometer which detects acceleration and the side gravity acceleration value of this acceleration sensor is detected and the wheel speed input from two wheel speed sensors in diagonal direction is added when it is less than the predetermined limit value and compared with the wheel speed added in the relative diagonal azimuth direction Therefore, if the difference value is calculated to be larger or smaller than the set value and it is maintained for a predetermined time, the electronic controller generates a predetermined level of voltage at the output stage and the alarm generating means driven by the voltage signal generated at the output stage of the electronic controller. Is done.

본 발명은 저렴한 비용으로 타이어의 공기압이 저하되어 있음을 청각적으로 운전자에게 경고하여 줄수 있으므로 발생에 의한 안전사고를 미연에 예방할 수 있는 장점이 있다.The present invention can alert the driver audibly that the air pressure of the tire is lowered at a low cost, and thus has an advantage of preventing safety accidents due to occurrence.
