Abstract

이 발명은 차속을 감지하는 휠속도센서(Wheel speed sensor)를 구비한 자동차에 적용되어 실화 감지로직의 적용/비용을 제어하기 위한 방법에 관한 것으로서, 자동차의 속도를 감지하는 휠 속도센서의 출력신호를 입력받는 제1단계와; 상기 제1단계에서 입력된 휠 속도센서의 출력신호를 시간 영역에서 소정 수로 나어진 세그먼트 단위로 적분하는 제2단계와; 상기 제2단계에서 적분된 값을 필터링하여 도로의 거친정도(A)를 계산하는 제3단계와; 매핑방식에 의해 미리 저장되어 있는 도로이 거친정도를 판정하기 위한 기준치(B)를 페취하는 제4단계와; 상기 제3단계에서 계산된 도로의 거친정도 (A)가 상기 제4단계에서 페취된 기준치(T)보다 큰지를 판단하는 제5단계와; 상기 제5단계에서 도로의 거친정도 (A)가 기준치 (B)보다 작을 경우, 실화 감지로직이 실행되도록 하는 제6단계로 구성되어, 휠 속도센서의 신호를 세그먼트 적분하여 도로의 거친 정도를 계산하고, 이를 소정의 기준치와 비교하여 도로의 거친 정도가 심할 경우에는 실화감지로직이 실행되지 않도록 함으로써 도로의 불규칙한 바운드에 의한 엔진의 불규칙함을 실화인 것으로 잘못 판정하는 오류를 방지할 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling application / cost of misfire detection logic applied to a vehicle having a wheel speed sensor for detecting a vehicle speed, and output signal of a wheel speed sensor for detecting a speed of a vehicle. Receiving a first step; A second step of integrating the output signal of the wheel speed sensor input in the first step in units of segments divided by a predetermined number in a time domain; A third step of calculating a roughness A of the road by filtering the integrated value in the second step; A fourth step of fetching the reference value B for determining the roughness of the road stored in advance by the mapping method; A fifth step of determining whether the roughness A of the road calculated in the third step is greater than the reference value T fetched in the fourth step; In the fifth step, if the roughness (A) of the road is less than the reference value (B), the sixth step of performing misfire detection logic is performed, and segment integration of the signal of the wheel speed sensor to calculate the roughness of the road. When the roughness of the road is severe compared to the predetermined reference value, the misfire detection logic is not executed so that an error of incorrectly determining the irregularity of the engine due to the irregular bound of the road as a misfire can be prevented.
