Description

엔진의 점화시기제어방법{control method of ignition of engine for vehicle}Control method of ignition of engine

본 발명은 엔진의 점화시기제어방법에 관한 것으로서 더 자세하게는 크랭크 회전각도에 대한 점화시기를 두의 영역으로 분리하여 각각의 점화시간을 연산할 수 있도록 하여 시간 변동에 의한 오차를 줄일 수 있는 엔진의 점화시기제어방법에 관한 것이다.The present invention relates to a method for controlling an ignition timing of an engine, and more particularly, to separate an ignition timing for a crank rotation angle into two regions so that each ignition time can be calculated to reduce an error due to time variation. An ignition timing control method.

일반적으로 차량의 엔진부품에 있어서의 운동부품은 왕복운동하는 피스톤, 피스톤의 왕복운동을 회전운동으로 변환하는 크랭크축과 커넥팅로드, 크랭크회전에 동기하여 1/2의 속도로 회전하는 캠축, 캠의 회전에 의해 개폐되는 흡기밸브등으로 되어 있다.In general, a moving part in an engine part of a vehicle includes a reciprocating piston, a crank shaft for converting the reciprocating motion of the piston into a rotary motion, a connecting rod, a cam shaft rotating at a speed of 1/2 in synchronization with the crank rotation, and a cam. An intake valve is opened or closed by rotation.

이러한 종래의 엔진은 점화시기가 흡기량, 공연비가 함께 일정하고, 점화시기를 변환시켰을 경우의 실린더내 압력은 점화시기를 진각시킬수록 최고압력이 높아지고 또한 최고 압력의 위치도 상사점(TDC)에 가까워지게 된다.In such a conventional engine, the ignition timing is constant with the intake amount and the air-fuel ratio, and when the ignition timing is changed, the in-cylinder pressure increases as the ignition timing advances, and the position of the maximum pressure is close to the top dead center (TDC). You lose.

이론상의 정적연소는 상사점에서 압축압력으로부터 연소에 의해 최고 압력이 되는 파형이 가장 출력, 효율이 높아진다.Theoretically, the static combustion has the highest output and efficiency with the waveform that becomes the highest pressure by combustion from compression pressure at the top dead center.

이와 같은 종래 엔진의 상사점은 엔진 크랭크 축의 움직임 각을 감지하기 위한 크랭크각센서를 통해 각 기통의 상사점(TDC)신호로부터 점화시기를 제어하는 것으로서, 도 1에서 보는 바와 같이 (a)는 크랭크각 센서가 감지한 크랭크의 각도에 대한 전기적인 신호로서, 이 경우 목표점화시기는 고정된 크랭크각의 상하강 각도를 기준으로 한기통당(6기통의 경우 120。)의 각도와 걸린시간으로 QR 즉 하사점The top dead center of the conventional engine is to control the ignition timing from the top dead center (TDC) signal of each cylinder through a crank angle sensor for detecting the movement angle of the engine crank shaft, as shown in Figure 1 (a) is a crank The electrical signal of the angle of the crank detected by each sensor. In this case, the target ignition timing is QR, which is the angle and time taken per cylinder (120 ° for 6 cylinders), based on the up and down angle of the fixed crank angle. Bottom dead center

75。에서 목표 점화시기까지의 시간을 산출하여 시간은 다음 같이 시간제어하고 있다.The time from 75 ° to the target ignition time is calculated and the time is controlled as follows.

TA=QR-QADV/120。*TF (QADV 는 목표점화시기이며, TA는 크랭크각 센서가 크랭크각의 변화를 감지하기 시작한 이후의 점화신호이고, TF는 6기통을 기준으로한 크랭크각 120。이다.)TA = QR-QADV / 120。 * TF (QADV is the target firing time, TA is the ignition signal after the crank angle sensor starts to detect the change in crank angle, and TF is the crank angle 120 ° based on 6 cylinders. to be.)

그러나 이러한 종래의 점화시간제어방법은 크랭크각의 전회전상태의 걸린시간인 TF가 크랭크축이 가 감속상태로 회전하게 되는 경우 TF는 당회의 점화시기을 계산하기 의해서는 오차가 수반되므로 점화신호가 일정시간 연장되므로 점화시간을 정확하게 제어할 수 없는 문제점을 가지고 있다.However, in the conventional ignition time control method, when the TF, which is the time taken in the full rotation state of the crank angle, rotates to the deceleration state of the crankshaft, the TF is accompanied by an error by calculating the ignition timing of the present time, so that the ignition signal is constant. Since the time is extended, the ignition time cannot be accurately controlled.

본 발명은 이와 같은 종래의 제반 문제점을 해결하기 위한 것으로서 그 목적은 크랭크 회전각도에 대한 점화시기를 두의 영역으로 분리하여 각각의 점화시간을 연산할 수 있도록 하여 시간 변동에 의한 오차를 줄이고자 하는 데 있다.The present invention is to solve such a conventional problem, the object is to separate the ignition timing for the crank rotation angle into two areas to calculate the respective ignition time to reduce the error caused by time variation There is.

도 1은 종래의 점화시기를 제어하기 위한 그래프이다.1 is a graph for controlling a conventional ignition timing.

도 2는 본 발명의 실시예에 따른 점화시기를 제어하기 위해 점화시기를 두 개의 영역으로 나누어 연산하기 위한 그래프이다.2 is a graph for calculating the ignition timing divided into two areas in order to control the ignition timing according to an embodiment of the present invention.
