Abstract: 내연기관에서 노킹 검출에 따른 점화시기 제어를 함에 있어서 엔진 회전수가 가이드(Guide)의 조건을 만족하는 경우 두 실린더간 상관 계수를 연산하여 노킹 강도에 따라 점화시기를 제어하도록 함으로써 엔진 출력에 안정성을 제공하도록 하는 것으로,
엔진 시동 온을 유지하는 상태에서 검출되는 노킹 강도를 계산하며, 현재의 엔진 회전수가 가이드 조건을 만족하는지를 판단하는 과정과, 가이드 조건을 만족하지 않으면 노킹 검출 실린더에 대해서만 점화시기 제어를 수행하고, 가이드 조건을 만족하는 경우 설정된 맵 테이블로부터 노킹 검출 실린더에 가이드 되는 실린더에 대한 노킹 발생 상관계수를 추출하는 과정과, 노킹 발생 상관계수가 상관계수와 검출되는 노킹값의 관계로부터 가이드되는 실린더의 노킹 강도를 계산하여 설정된 임계값과 비교하는 과정과, 상기에서 계산된 노킹 강도가 임계값 이하면 점화시기 지각 제어를 수행하지 않고, 임계값 이상이면 노킹 강도에 따라 점화시기를 지각 제어하는 과정을 포함한다.-

Abstract: PURPOSE: A knocking control method of a gasoline engine is provided to minimize loss of performance of the engine by restricting excessive retard of ignition time with controlling knocking through the air-fuel ratio control. CONSTITUTION: In the ignition time control step, ignition time retards and returns in knocking an engine(ST100). In the density control step of air-fuel ratio, the air-fuel ratio according to each cylinder is controlled in case of the retard of ignition time to be over the critical value(ST200). An ECU decides the knocking operation range by receiving signals from a knocking sensor(ST110), and calculates the knocking intensity in deciding the knocking operation range(ST120). Ignition time returns if the knocking intensity is below the threshold value, and retards if the knocking intensity is over the threshold value(ST141,ST142). The air-fuel ratio enrichment learning value is returned in case of the ignition time retard to be less than the threshold value(ST231), and the air-fuel ratio according to each cylinder is calculated in case of the ignition time retard to be over the threshold value(ST232). The air-fuel ratio enrichment corresponding to each cylinder is stored for next learning(ST240).
