본 발명은 점화 제어방법에 관한 것으로, 특히 점화 제어를 위한 점화시기와 드웰각(Dwell Angle)을 메모리에 저장하고, 이 데이터를 읽어 드웰 온시점이 현 BTDC 114도를 넘는지를 판단하고, 드웰 온 시점이 현 BTDC 114도를 넘는다고 판단되면, 상기 드웰 온시점을 전 BTDC 114도를 기준으로 제어하여 저회전시의 응답지연 방지 및 진/지각시의 안정된 드웰각 제어를 실시할 수 있도록 한 점화 제어방법에 관한 것이다.The present invention relates to an ignition control method, and particularly, to store an ignition timing and a dwell angle for ignition control in a memory, and to read this data to determine whether the dwell on time exceeds the current BTDC 114 degrees, and the dwell on If it is determined that the time point exceeds the current BTDC 114 degrees, the dwell on time is controlled based on the entire BTDC 114 degrees to prevent response delay at low rotations and to perform stable dwell angle control at the time of the earthquake and the perception. It relates to a control method.

종래의 점화 제어방법은 드웰각의 제어를 이전 BTDC 114도를 기준으로 제어하고, 점화시기는 가/감속에 대해 응답지연을 제거하기 위해 현 BTDC 114도를 기준으로 제어를 한다.The conventional ignition control method controls the control of the dwell angle based on the previous BTDC 114 degrees, and the ignition timing is controlled based on the current BTDC 114 degrees to remove the response delay for acceleration / deceleration.

즉, 제1도의 (a)와 같이 티디씨(TDC) 파형이 진행될 때, 통전제어는 고/저회전에 대한 구분 필요없이 제어가 되며, 이때 항시 180°의 지연시간이 발생한다.That is, when the TDC waveform progresses as shown in (a) of FIG. 1, the energization control is controlled without the need for high / low rotation, and a delay time of 180 ° is always generated.

그리고, 제1도의 (a)와 같이 티디씨 파형이 진행될 때, 점화제어는 기준점 즉, 현재의 BTDC 114도를 기준으로 제어되며, 가/감속에 대한 응답시간이 빠르다.In addition, when the TCD waveform progresses as shown in (a) of FIG. 1, the ignition control is controlled based on the reference point, that is, the current BTDC 114 degrees, and the response time for acceleration / deceleration is fast.

이때, 기준점이 다름으로 인해 시스템 로직의 모순과 과도 상태 처리동작이 필요하다.In this case, contradiction of the system logic and transient state processing operations are necessary because of different reference points.

과도상태 판정은 제1도의 (b)에 도시된 현 점화구간(A)과 이전 드웰각 제어구간(B)의 차이값이 2보다 작을 때를 과도상태로 판정하고, 과도상태가 판정되면 점화구간의 변동폭을 이전 드웰각 제어구간(B)에 더해서 새로운 드웰구간을 설정한다.The transient state determination determines the transient state when the difference value between the current ignition section A and the previous dwell angle control section B shown in (b) of FIG. 1 is less than 2, and when the transient state is determined, the ignition section The new dwell interval is set by adding the variation of to the previous dwell angle control interval (B).

상기 설명과 같은 종래의 점화제어방법은 점화시기 제어를 위한 구동 콘트롤수단이 2개 필요하고, 소프트웨어적 처리가 어려우며, 드웰각의 응답 지연이 발생되고, 점화 진/지각시 드웰각이 감소하는 문제점이 있었다.Conventional ignition control method as described above requires two drive control means for ignition timing control, difficult software processing, delay response of the dwell angle occurs, dwell angle is reduced during ignition / late There was this.

따라서, 상기 문제점들을 해결하기 위한 본 발명은 점화제어를 위한 점화시기와 드웰각(Dwell Angle)을 메모리에 저장하고, 이 데이터를 읽어 드웰 온시점이 BTDC 114도를 넘는지를 판단하고, 드웰 온시점이 현 BTDC 114도를 넘는다고 판단되면, 상기 드웰 온시점을 전 BTDC 114도를 기준으로 제어하여 저회전시의 응답지연 방지 및 진/지각시의 안정된 드웰각 제어를 실시할 수 있도록 한 점화 제어방법을 제공함을 목적으로 한다.Therefore, in order to solve the above problems, the present invention stores an ignition timing and a dwell angle for ignition control in a memory, reads the data to determine whether the dwell on time exceeds BTDC 114 degrees, and the dwell on time. When it is determined that the current BTDC exceeds 114 degrees, the ignition control is performed to control the dwell on time based on the entire BTDC 114 degrees to prevent response delay at low rotation and to perform stable dwell angle control at the time of true / delay. The purpose is to provide a method.
