Abstract

본 발명은 차량에 구비되어 있는 4개의 타이어의 압력을 측정하고, 이상이 있을 경우에 이를 경보하는 것이다.The present invention measures the pressure of four tires provided in a vehicle, and alerts when there is an abnormality.

본 발명은 차량에 설치되어 있는 기존의 센서들의 신호를 이용하여 타이어의 압력을 정확하게 측정하고 이상이 있을 경우에 이를 경보하는 것으로서 각각의 타이어의 회전축에 설치되어 회전 속도를 검출하는 4개의 회전 속도 센서와, 차량의 주행 속도를 검출하는 차속 센서와, 차량의 좌우 진동을 검출하는 횡 가속도 센서와, 차량의 상하 진동을 검출하는 2개의 종 가속도 센서와, 조향 핸들의 회전속도를 검출하는 조향각 센서와, 드로틀 밸브의 개폐 정도를 검출하는 드로틀 센서의 신호를 마이크로 프로세서(7)가 입력하여 타이어의 압력을 퍼지 추론하고, 퍼지 추론한 결과 타이어의 압력에 이상이 있을 경우에 경보 제어신호를 출력하며, 출력한 경보 제어신호에 따라 표시 구동부(8)가 표시부(9)를 제어하여 타이어의 압력에 이상이 있음을 경보한다.The present invention relates to an apparatus and a method for accurately measuring pressure of a tire using signals of existing sensors installed in a vehicle and alerting the tire when an abnormality occurs, A vehicle speed sensor for detecting the running speed of the vehicle, a lateral acceleration sensor for detecting the lateral vibration of the vehicle, two longitudinal acceleration sensors for detecting the vertical vibration of the vehicle, a steering angle sensor for detecting the rotational speed of the steering wheel, A microprocessor 7 inputs a signal of the throttle sensor for detecting the degree of opening and closing of the throttle valve, falsely inferring the pressure of the tire, and outputs an alarm control signal when the pressure of the tire is abnormal due to fuzzy reasoning, In response to the output alarm control signal, the display driver 8 controls the display 9 to warn that the pressure of the tire is abnormal .
