Description
본 발명은 녹킹 제어 방법에 관한 것으로서, 보다 상세하게는 각 rpm마다 녹킹의 경향을 미리 파악한 후, 각 rpm마다의 녹킹 발생시의 리타드양을 다르게 설정하여 정확하게 리타드되므로서, 효과적으로 녹킹을 저감할 수 있는 녹킹 제어 방법(KNOCKING CONTROL METHOD)에 관한 것이다.The present invention relates to a knocking control method, and more particularly, after grasping the tendency of knocking at each rpm in advance, by setting the retard amount at the time of knocking occurrence at each rpm differently, it is possible to effectively reduce knocking. KNOCKING CONTROL METHOD.
종래에는 엔진의 녹킹 제어 방법은 녹킹이 발생하면, 소정량을 리타드(retard)하도록 되어 있었다. 그러므로, 녹킹의 경향이 각각 다름에도 불구하고, 항상 일정하게 리타드하므로서 출력 손실이 큰 문제점이 있었다.Conventionally, the knocking control method of an engine is to retard a predetermined amount when knocking occurs. Therefore, although the tendency of knocking is different, there is a problem in that the output loss is large because it is constantly retarded at all times.
따라서, 본 발명은 상기 문제점들을 해소하기 위해 제안된 것으로, 본 발명의 주 목적은 엔진의 초기 정합시, 각 rpm마다의 녹킹의 경향에 따라, 리타드양을 다르게 설정하여 정확하게 리타드되도록 한 녹킹 제어 방법을 제공하는 것이다.Therefore, the present invention has been proposed to solve the above problems, the main object of the present invention is the knocking control to accurately retard by setting the retard amount differently according to the tendency of knocking at each rpm during the initial matching of the engine To provide a way.
상술한 바와 같은 목적을 달성하기 위해, 본 발명에 따른 녹킹 제어 방법은 녹킹 발생 포인트의 알피엠별 리타드양을 감지하는 단계와, 감지된 리타드량에 해당하는 알피엠 영역을 메모리하는 단계와, 발생된 녹킹 포인트를 상기 메모리된 알피엠 영역인가를 확인하는 단계와, 확인된 알피엠 영역이면, 해당하는 양으로 리타드하는 단계로 이루어진 것을 특징으로 한다.In order to achieve the object as described above, the knocking control method according to the present invention comprises the steps of detecting the amount of retard for each RMP of the knocking generation point, the step of memory of the RMP area corresponding to the detected amount of retard, knocking generated And confirming whether or not a point is the memorized ALPM region, and retreading a corresponding amount if the identified ALPM region.
본 발명의 일실시예에 따르면 녹킹 발생 포인트를 0.5°단위로 하여 점화시기를 제어하는 것이 바람직하다.According to an embodiment of the present invention, it is preferable to control the ignition timing based on the knocking generation point by 0.5 °.
도 1은 본 발명에 따른 녹킹 제어 방법을 나타내는 순서도이다.1 is a flowchart showing a knocking control method according to the present invention.
이하, 첨부된 도면을 참조로 하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;
도 1은 본 발명의 바람직한 일 실시예에 따른 녹킹 제어 방법의 제어 단계에 나타내고 있다.Figure 1 shows in the control step of the knocking control method according to an embodiment of the present invention.
본 발명의 녹킹 제어 방법은, 먼저, 단계 S1에서, 녹킹 발생 포인트의 알피엠별 리타드양을 감지한다. 이때, 녹킹이 0.5°차이를 두고 발생한다는 보장이 없으므로, 0.5°단위로 점화시기를 제어할 수 있으며, 좋은 것이다. 이어서, 단계 S2에서, 감지된 리타드량에 해당하는 알피엠 영역을 메모리한다.In the knocking control method of the present invention, first, in step S1, the amount of retards per ALMP of the knocking generation point is detected. At this time, since there is no guarantee that knocking occurs with a 0.5 ° difference, the ignition timing can be controlled in 0.5 ° units, which is a good thing. Subsequently, in step S2, the RMP area corresponding to the detected retard amount is stored.
다음 단계 S3에서는, 발생된 녹킹 포인트를 이미 메모리된 알피엠 영역인가를 확인한 후, 단계 S4에서, 확인된 알피엠 영역이면, 해당하는 양으로 리타드하므로서 녹킹 제어를 더욱 효과적으로 하게 된다.In the next step S3, after confirming whether or not the generated knocking point is already stored in the ALMP area, in step S4, if the identified ALMP area is retreaded by a corresponding amount, knocking control is more effectively performed.
이러한 단계로 이루어지는 녹킹 제어 방법은 일정 시간이 경과한 후에는 메모리를 리셋시키는 것이 바람직함은 물론이다.Of course, in the knocking control method having such a step, it is preferable to reset the memory after a predetermined time has elapsed.
상기와 같은 본 발명의 녹킹 제어 방법은 엔진의 초기 정합시, 각 rpm마다의 녹킹의 경향에 따라, 리타드양을 다르게 설정하여 정확하게 리타드되도록 하므로서, 녹킹을 효과적으로 제어하는 효과를 가진다.The knocking control method of the present invention as described above has an effect of effectively controlling knocking by setting the retard amount differently according to the tendency of knocking at each rpm, so as to accurately retard the engine.
