Abstract

이 발명은 3점을 이용한 센서의 고장 판정 방법에 관한 것으로서, 일정한 운전 조건을 만족하는 자동차의 속도나 온도를 가지는 단계와; 엔진 회전수가 상한치 엔진 회전수보다 큰 조건과, 엔진 부하가 상한치 엔진 부하보다 더 크게 걸리는 단계와; 엔진 회전수가 하한치 엔진 회전수보다 적은 조건과, 엔진 부하가 하한치 엔진 부하보다 적게 걸리는 단계와; 엔진 회전수가 하한치 엔진 회전수보다 크고 상한치 엔진 회전수보다 작은 경우와 엔진 부하가 하한치 엔진 부하보다 크고 상한치 엔진 부하보다 작은 단계와; 센서 출력이 제1중간치 출력보다 크고, 제2중간치 센서 보다 작은 경우의 단계와; 상기의 조건을 모두 충족하여 정상 판결을 내리는 단계와; 센서 출력이 상한치 센서 출력보다 큰 단계와; 센서 출력이 하한치 센서 출력보다 작은 단계와; 상기 극단치 이상의 경우 고장 판결을 내리는 단계로 이루어지며; 상한치와 하한치 사이에 한 개의 점을 더 추가하여, 센서의 출력의 여부를 점검하여서 적은 비용과 시간으로 센서의 정확도를 판단할 수 있는 효과를 가진 3점을 이용한 센서의 고장 판정 방법에 관한 것이다.The present invention relates to a method for determining a failure of a sensor using three points, the method comprising: having a speed or temperature of a vehicle satisfying a predetermined driving condition; A condition where the engine speed is greater than the upper limit engine speed and the engine load is greater than the upper limit engine load; A condition in which the engine speed is less than the lower limit engine speed and the engine load is less than the lower limit engine load; When the engine speed is greater than the lower limit engine speed and less than the upper limit engine speed, and the engine load is greater than the lower limit engine load and less than the upper limit engine load; When the sensor output is greater than the first intermediate value output and smaller than the second intermediate value sensor; Satisfying all of the above conditions and making a normal judgment; The sensor output is greater than the upper limit sensor output; The sensor output is smaller than the lower limit sensor output; In case of an extreme value or more, making a decision of failure; The present invention relates to a method for determining a failure of a sensor using three points, by adding one more point between an upper limit value and a lower limit value, and checking the output of the sensor to determine the accuracy of the sensor at low cost and time.
