Description
본 발명은 퍼지 도입에 따른 엔진의 안정성을 유지시키기 위한 방법에 관한 것으로서, 특히 퍼지 적용시 퍼지 듀티량에 따라 공기량 및 연료량을 일정량 감소시킴으로써 엔진의 안정성을 향상시킬 수 있는 퍼지 도입에 따른 아이들 스피드 컨트롤 반비례 제어 방법에 관한 것이다.The present invention relates to a method for maintaining the stability of the engine according to the introduction of the purge, in particular, idle speed control according to the introduction of the purge to improve the stability of the engine by reducing the amount of air and fuel according to the amount of purge in purge application The inverse control method.
엔진의 아이들 스피드 컨트롤 제어 방법에 있어서 퍼지(purge)를 도입하면 공기량이 증대되고, 공기량의 증가에 따라 연료량 또한 증가된다. 그런데, 종래의 아이들 스피드 컨트롤 제어 방법에서는 퍼지 적용에 따른 듀티(duty)량을 공기량이나 연료량 연산에 적용하지 않아 공기량 및 연료량이 과다하게 되므로 엔진의 안정성(stability)이 약해지는 경우가 있다.In the engine idle speed control control method, the introduction of a purge increases the amount of air, and the amount of fuel also increases as the amount of air increases. However, in the conventional idle speed control control method, since the duty amount according to the purge application is not applied to the calculation of the air amount or the fuel amount, the air amount and the fuel amount become excessive, so that the stability of the engine may be weakened.
퍼지는 연료탱크 내에서 증발된 연료증발가스를 흡기측으로 공급하는 것을 말하며, 흡기측으로 연료증발가스가 공급됨에 따라 엔진으로 실제로 공급하는 공기량 및 연료량은 공기량 센서가 계측한 값과는 달라지게 된다.Purge refers to supplying the evaporated fuel evaporation gas in the fuel tank to the intake side. As the fuel evaporation gas is supplied to the intake side, the air amount and fuel amount actually supplied to the engine are different from the values measured by the air volume sensor.
따라서, 엔진의 안정성을 확보하기 위해서는 퍼지가 적용되더라도 엔진의 안정성이 유지되도록 퍼지 적용에 따른 공기량 및 연료량 등 파라미터(parameter)의 변화를 살펴 적정한 공기량 및 연료량이 엔진으로 공급되도록 이들을 제어할 필요가 있다.Therefore, in order to secure the stability of the engine, even if the purge is applied, it is necessary to control them so that the appropriate air amount and fuel amount are supplied to the engine by looking at the change of parameters such as the air amount and fuel amount according to the purge application to maintain the engine stability. .
본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 퍼지 적용시 퍼지 듀티량을 연산하여 ECU가 연산하는 공기량 및 연료량 파라미터를 일정 정도 감소시킴으로써, 아이들시 퍼지 적용에 따른 엔진의 안정성 불안을 해소시킬 수 있는 퍼지 도입에 따른 아이들 스피드 컨트롤 반비례 제어 방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, by calculating the purge duty amount during the purge application by reducing the amount of air and fuel amount parameters calculated by the ECU to a certain degree, the stability of the engine in response to the purge application during idle The purpose of the present invention is to provide an inverse control method of idle speed control according to the introduction of fuzzy to solve the problem.
도 1은 본 발명에 의한 퍼지 도입에 따른 아이들 스피드 컨트롤 반비례 제어 방법이 도시된 순서도이다.1 is a flowchart illustrating a method for inversely controlling an idle speed control according to a purge introduction according to the present invention.

상기한 목적을 달성하기 위한 본 발명은 퍼지 적용 여부를 확인하는 제1단계와, 퍼지 적용에 따른 듀티변화량을 연산하는 제2단계와, 듀티변화량에 따라 연료량을 매칭하고 각 파라미터의 위치를 변경하는 제3단계와, 엔진 회전수의 변화를 계산하여 엔진 회전수 변동량이 일정치 이하가 될 때까지 제2단계로 피드백 하는 제4단계로 구성된 것을 특징으로 한다.The present invention for achieving the above object is a first step of confirming whether or not to apply the purge, the second step of calculating the duty change amount according to the purge application, matching the fuel amount according to the duty change amount and changing the position of each parameter And a fourth step of calculating a change in the engine speed and feeding back to the second step until the engine speed variation becomes less than a predetermined value.
이하, 본 발명의 실시 예를 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 퍼지 도입에 따른 아이들 스피드 컨트롤 반비례 제어 방법은 도 1에 도시된 바와 같이 퍼지(purge) 적용 여부를 확인하는 제1단계와, 퍼지 적용에 따른 듀티(duty)량을 연산하는 제2단계와, 듀티(duty)변화량에 따라 연료량을 매칭하고 각 파라미터(parameter)의 위치를 변경하는 제3단계와, 엔진 회전수(Ne)의 변화를 계산하여 엔진 회전수 변동량(dNe)이 일정치(α) 이하가 될 때까지 제2단계로 피드백(feed-back) 하는 제4단계로 구성된다.As shown in FIG. 1, the idle speed control inversely proportional control method according to the present invention includes a first step of checking whether a purge is applied and a second step of calculating a duty amount according to the purge application. And a third step of matching the fuel amount according to the duty change amount and changing the position of each parameter, and calculating the change in the engine speed Ne by a constant value of the engine speed variation dNe ( and a fourth step of feeding back to the second step until α) or less.
상기와 같이 구성된 본 발명의 퍼지 도입에 따른 아이들 스피드 컨트롤 반비례 제어 방법은 퍼지가 도입되어 적용될 경우 공기량과 연료량을 일정량 감소시켜 엔진의 안정성이 유지되도록 하게 된다.Inversely proportional control method for idle speed control according to the introduction of the purge of the present invention configured as described above is to maintain the stability of the engine by reducing a certain amount of air and fuel amount when the purge is introduced and applied.
먼저 퍼지(purge)의 적용 여부를 확인하고 퍼지에 따른 듀티(duty)변화량을 연산한다. 퍼지에 따른 듀티변화량이 연산되면 듀티변화량에 따라 연료량 매칭(matching)을 다시 실시하고, 각 파라미터(parameter)의 위치를 변경하여 퍼지 적용에 따라 그 값들이 정상적으로 적용될 수 있도록 하게 된다.First, check whether a purge is applied and calculate a duty change amount according to the purge. When the duty change amount according to the purge is calculated, fuel quantity matching is performed again according to the duty change amount, and the position of each parameter is changed to allow the values to be normally applied according to the purge application.
연료량 매칭과 파라미터의 위치 변경이 끝나면 그에 따른 엔진 회전수(Ne)의 변화를 계산한다. 계산된 엔진 회전수 변동량(dNe)이 일정치(α) 이상이면 퍼지에 따른 듀티량을 다시 연산하여 상기의 과정을 되풀이하고, 일정치(α) 이하이면 엔진의 안정성(stability)이 확보된 것으로 간주하고 아이들 스피드 컨트롤 제어를 종료한다.After the fuel quantity matching and the parameter position change are completed, the change in the engine speed Ne is calculated accordingly. If the calculated engine speed variation dNe is greater than or equal to a value α, the duty cycle according to the purge is recalculated, and if the engine speed is less than or equal to α, stability of the engine is secured. Regards and exits idle speed control control.
이와 같이, 본 발명의 퍼지 도입에 따른 아이들 스피드 컨트롤 반비례 제어 방법은 퍼지를 적용하는 경우 공기량 및 연료량을 일정량 감소시키게 되므로 과다한 공기량에 의한 오차가 줄게 되어 아이들 상태에서 퍼지 적용시 엔진의 안정성이 향상되는 이점이 있다.As described above, the idle speed control inversely proportional control method according to the present invention reduces the amount of air and fuel when the purge is applied, thereby reducing the error caused by the excessive amount of air, thereby improving the stability of the engine when applying the purge in the idle state. There is an advantage.
