Description

차량서지방지를 위한 점화제어방법Ignition Control Method for Vehicle West Area

본 발명은 차량서지방지를 위한 점화제어방법에 관한 것으로서, 더욱 구체적으로 운전자의 가속의지가 있는 상태, 즉 스로틀밸브개도의 변화량이 많은 상태이거나, 실제적으로 차량서지가 일어나지 않는 상태, 즉 차속이 느린 공회전상태에서는 차량서지방지를 위하여 점화시기를 어드밴스 또는 리타드하지 않도록 하여 차량운전성, 엔진출력 및 연비를 향상시키는 차량서지방지를 위한 점화제어방법에 관한 것이다.The present invention relates to an ignition control method for a vehicle western region, and more specifically, to a state in which the driver is willing to accelerate, that is, a state in which a large amount of change in the throttle valve opening is present, or a state in which a vehicle surge does not actually occur, that is, a vehicle speed is slow. The present invention relates to an ignition control method for a vehicle terrain area, which improves vehicle operability, engine output and fuel efficiency by preventing the ignition timing from being advanced or retarded for the vehicle terrain area.

차량의 서지(surge)는 엔진부하의 갑작스러운 변동에 따라 자동차가 전후방향으로 10 Hz 이하의 주파수로 흔들리는 현상을 말한다. 이는 정상주행중 가속페달의 갑작스러운 조작으로 인한 엔진출력의 급격한 변화, 실화등이 원인이 되어 발생하는 미세한 진동을 말하며 급가속이나 변속에 따라 엔진에 급격한 부하변동이 일어나고 동력전달계통에 급격한 비틀림진동이 발생하는 현상이다.Surge of the vehicle refers to a phenomenon in which the vehicle shakes at a frequency of 10 Hz or less in the front-rear direction due to a sudden change in the engine load. This is a minute vibration caused by sudden change of engine output or misfire due to sudden operation of the accelerator pedal during normal driving.The rapid load fluctuation occurs in the engine due to rapid acceleration or shift and sudden torsional vibration in the power transmission system. It is a phenomenon that occurs.

종래 상기와 같은 차량서지가 발생하는 것을 방지하는 방법은 다음과 같이 행해졌다. 도 1은 일반적인 자동차점화제어장치의 블록도이고, 도 2는 종래 차량서지방지를 위한 점화제어방법을 실행하는 플로우챠트이다.Conventionally, a method of preventing the occurrence of such a vehicle surge has been performed as follows. 1 is a block diagram of a general vehicle ignition control apparatus, and FIG. 2 is a flowchart for executing a ignition control method for a conventional vehicle west region.

일반적으로 자동차점화제어장치는 공가흐름센서, 엔진회전수센서, 흡기온도센서, 냉각수온센서, 스로틀포지션센서, 아이들스위치, 차속센서, 점화스위치, 크랭크각센서 등으로 부터 신호를 받고 그들 신호에 따라 점화제어를 행하는 ECU(1), 축전지의 전압을 승압하여 고압전류를 발생하는 점화코일(2), 축전지의 전압을 상기 점화코일(2)로 스위칭하는 점화스위치(3), 상기 점화코일(2)의 1차코일에 전류를 흐르게 하는 것으로서 ECU(1)의 제어에 의해서 스위칭하는 파워트랜지스터(4), 실린더에 설치되어 점화작용을 행하는 점화플러그(5), 그리고 상기 점화코일(2)로 부터의 고압전류를 각각의 점화플러그(5)에 배분하는 배전기(6)로 이루어져 있다.In general, the car ignition control device receives signals from idle flow sensor, engine speed sensor, intake air temperature sensor, coolant temperature sensor, throttle position sensor, idle switch, vehicle speed sensor, ignition switch, crank angle sensor, etc. ECU 1 for ignition control, an ignition coil 2 for boosting the voltage of the battery to generate a high voltage current, an ignition switch 3 for switching the voltage of the battery to the ignition coil 2, and the ignition coil 2 The current flows through the primary coil of the power supply transistor (4) for switching by control of the ECU (1), the ignition plug (5) installed in the cylinder to perform the ignition action, and from the ignition coil (2) It consists of a distributor 6 for distributing the high-voltage current of each to the spark plug (5).

상기 점화장치는 각 센서로 부터의 신호에 따라 엔진회전수, 부하, 엔진온도 등의 엔진상태를 검출해서 그 상태에 대한 최적의 점화시기를 ECU(1)에서 연산하여 1차 전류를 스위칭하는 신호를 파워트랜지스터(4)에 출력하여 점화코일(2)에서 고압의 2차 전류가 발생하도록 하고 이를 배전기(6)가 해당 점화플러그(5)에 배분하여 점화가 이루어지도록 한다.The ignition device detects an engine state such as an engine speed, a load, an engine temperature, etc. according to a signal from each sensor, and calculates an optimum ignition timing for the state by switching the primary current. Is output to the power transistor (4) to generate a high-pressure secondary current in the ignition coil (2) and distributes it to the ignition plug (5) so that the ignition is made.

상기와 같은 점화장치에 있어서 종래 차량서지방지를 위한 점화제어방법을 도 2를 참조하여 설명한다.In the above-described ignition apparatus, a conventional ignition control method for a vehicle west region will be described with reference to FIG.

우선 ECU(Electronic Contrl Unit)(1)는 엔진회전수센서로 부터의 신호에 의하여 엔진회전수가 차량서지방지를 위한 점화시기를 제어할 범위내에 있는지를 판단한다(제1단계, S1).First, the ECU (Electronic Control Unit) 1 judges whether the engine speed is within a range to control the ignition timing for the vehicle standing area by the signal from the engine speed sensor (first step, S1).

차량서지는 비교적 낮은 엔진회전수에서 일어나는데, 즉 공회전 내지 약 2000 rpm에서 주로 일어나는데, 이와 같은 엔진회전수범위는 미리 설정되어 그에 대응하는 데이터가 ECU(1)에 저장되어 있다. 따라서 ECU(1)는 엔진회전수가 차량서지방지를 위한 점화시기를 제어할 범위내에 있는지 판단할수 있다.The vehicle surge occurs at a relatively low engine speed, that is, mainly at idle to about 2000 rpm. The engine speed range is preset and the corresponding data is stored in the ECU 1. Therefore, the ECU 1 can determine whether the engine speed is within a range to control the ignition timing for the vehicle west region.

다음에 ECU(1)는 엔진부하가 일정값이하인지를 판단한다(제2단계, S2).The ECU 1 then determines whether the engine load is below a certain value (second step, S2).

ECU(1)는 엔진회전수센서로 부터의 엔진회전수와 공기흐름센서로 부터의 흡입공기량의 비율을 계산하여 엔진부하를 구하여 그 엔진부하가 미리 설정되어 일정값의 엔진부하이하인지를 판단한다.The ECU 1 calculates the ratio of the engine speed from the engine speed sensor to the intake air amount from the air flow sensor to obtain the engine load, and determines whether the engine load is predetermined and below the predetermined engine load. .

그리고 상기와 같은 엔진회전수와 엔진부하의 조건이 만족될 경우에 한하여 ECU(1)는 엔진회전수의 증가가 있는지를 판단하여(제3단계,S3), 엔진회전수증가가 있을 때에는 점화시기를 리타드(retard)시킨다(제4단계, S4).The ECU 1 determines whether there is an increase in the engine speed only when the conditions of the engine speed and the engine load as described above are satisfied (step 3, S3), and when the engine speed increases, the ignition timing Retard is retarded (fourth step, S4).

그리고 엔진회전수의 감소가 있는지를 판단하여(제5단계, S5), 엔진회전수감소가 있을 때에는 점화시기를 어드밴스(advance)시킨다(제6단계, S6).Then, it is judged whether or not the engine speed decreases (step 5, S5), and when the engine speed decreases, the ignition timing is advanced (step 6, S6).

상기와 같이 종래의 차량서지방지를 위한 점화제어방법은 엔진회전수와 엔진부하가 차량서지방지를 위한 점화제어조건이 만족된 상태에서 엔진회전수의 증가가 있으면 점화시기를 리타드시키고, 엔진회전수의 감소가 있으면 점화시기를 리타드시키는 방법으로 차량의 서지현상을 방지하도록 되어 있다.As described above, the conventional ignition control method for the vehicle local area retards the ignition timing when the engine speed increases when the engine speed and the engine load satisfy the ignition control conditions for the vehicle local area, and the engine rotates. If there is a reduction in number, the surge is prevented by retarding the ignition timing.

그러나 종래의 점화제어방법은 상기 차량서지방지를 위한 점화제어조건이 만족된 상태에서, 운전자가 가속페달을 밟을 때에도 차량서지가 일어나는 것으로 판단하여 점화시기를 리타드시킨다. 이는 가속페달을 밟을 때에는 오히려 점화시기를 어드밴스시켜야 하는데도 불구하고 차량서지가 일어나는 것으로 판단하여 점화시기를 리타드시키는 것이기 때문에 오히려 운전성이 좋지 않게 되는 현상을 유발하는 문제점이 있다.However, the conventional ignition control method retards the ignition timing by determining that the vehicle surge occurs even when the driver steps on the accelerator pedal while the ignition control condition for the vehicle standing area is satisfied. This is a problem that causes the phenomenon that the driving performance is not good because it is to retard the ignition timing by judging that the vehicle surge occurs even though the ignition timing should be advanced when stepping on the accelerator pedal.

그리고 공회전상태, 즉 차속이 느린 경우에 실제로는 차량서지가 일어나지 않는데도 불구하고 엔진회전수의 증감이 있을 때 차량서지가 일어나는 것으로 판단하여 점화시기를 리타드시킴으로 인하여 차량운전성이 저하되는 현상이 일어나는 문제점이 있었다.In the case of idling, that is, when the vehicle speed is slow, the driver's driving performance is deteriorated by retarding the ignition timing by judging that the vehicle surge occurs when the engine speed increases or decreases even though the vehicle surge does not actually occur. There was a problem that occurred.

본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위해서 안출된 것으로서, 엔진회전수와 엔진부하가 차량서지를 발생하는 조건을 만족한다 하더라도 실제적으로 차량서지가 일어나지 않는 일정이하의 저속인 때와 운전자가 가속페달을 밟을 때, 즉 스로틀밸브개도변화량이 클 경우에는 점화시기를 어드밴스시키거나 리타드시키지 않음으로 해서 운전성, 엔진출력, 연비의 저하를 방지하는 차량서지방지를 위한 점화제어방법를 제공하는데 그 목적이 있다.The present invention has been made to solve the problems of the prior art as described above, even when the engine speed and the engine load satisfies the conditions for generating the vehicle surge, and when the driver at a low speed below a certain level that does not actually cause the vehicle surge. Provides a ignition control method for vehicle standing areas that prevents deterioration of operability, engine output, and fuel efficiency by not advancing or retarding the ignition timing when the accelerator pedal is pressed, that is, when the throttle valve opening degree is large. The purpose is.

상기 목적을 달성하기 위한 본 발명의 차량서지방지를 위한 점화제어방법은 엔진회전수가 차량서지방지를 위한 점화시기를 제어할 일정범위내에 있는지를 판단하는 단계, 엔진부하가 차량서지방지를 위한 점화시기를 제어할 일정범위내에 있는지를 판단하는 단계를 포함하고, 그리고 차량서지방지를 위한 점화시기를 제어할 조건이 만족되는 상태에서 엔진회전수의 증가 있을 때 점화시기를 리타드하고 엔진회전수의 감소가 있을 때 점화시기를 어드밴스하는 점화제어방법에 있어서, 스로틀밸브의 변화량이 일정이하 그리고 차속이 일정이상인 경우에 한하여 차량서지방지를 위한 점화제어를 행하는 것을 특징으로 한다.In order to achieve the above object, an ignition control method for a vehicle west region of the present invention includes determining whether the engine speed is within a predetermined range to control the ignition timing for the vehicle west region, and the engine load is the ignition timing for the vehicle west region. Determining whether the engine is within a predetermined range to control the engine, and retarding the ignition timing and decreasing the engine speed when the engine speed is increased while the conditions for controlling the ignition timing for the vehicle west region are satisfied. In the ignition control method for advancing the ignition timing when there is, the ignition control for the vehicle standing area is performed only when the amount of change of the throttle valve is equal to or less than the constant and the vehicle speed is equal to or greater than the constant.

이하 첨부된 도면을 참조하여 본 발명의 차량서지방지를 위한 점화제어방법를 보다 상세히 설명하면 다음과 같다.Hereinafter, an ignition control method for a vehicle west region of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명의 차량서지방지를 위한 점화제어방법을 실행하는 플로우챠트이다. 본 발명의 차량서지방지를 위한 점화제어방법을 실행하기 위한 점화장치는 종래와 동일하다.3 is a flowchart for executing the ignition control method for the vehicle west region of the present invention. The ignition apparatus for executing the ignition control method for the vehicle west region of the present invention is the same as the conventional one.

우선 ECU(1)는 엔진회전수가 차량서지방지를 위한 점화시기를 제어할 일정범위내에 있는지를 판단한다(제1단계,S1).First, the ECU 1 determines whether the engine speed is within a predetermined range to control the ignition timing for the vehicle west region (first step, S1).

여기서 일정범위의 엔진회전수라 함은 차량서지가 일어나는 비교적 낮은 엔진회전수, 즉 공회전 내지 약 2000 rpm의 회전수를 의미하는 것으로서 상한의 엔진회전수는 차종마다 실험에 의해서 구해진다.Here, the engine speed in a range means a relatively low engine speed at which the vehicle surge occurs, that is, a speed of idle to about 2000 rpm. The upper limit of engine speed is obtained by experiment for each vehicle type.

그리고 ECU(1)는 엔진부하가 차량서지방지를 위한 점화시기를 제어할 일정범위내에 있는지를 판단한다(제2단계, S2).The ECU 1 then determines whether the engine load is within a certain range to control the ignition timing for the vehicle west zone (second step, S2).

ECU(1)는 엔진회전수센서로 부터의 엔진회전수와 공기흐름센서로 부터의 흡입공기량의 비율을 계산하여 엔진부하를 구하여 그 엔진부하가 미리 설정되어 일정값의 범위내의 엔진부하이하인지를 판단한다.The ECU 1 calculates the ratio of the engine speed from the engine speed sensor to the intake air amount from the air flow sensor to obtain the engine load, and determines whether the engine load is preset and the engine load is within a predetermined range. To judge.

이어서 ECU(1)는 스로틀포지션센서로 부터의 신호에 의해서 스로틀밸브의 개도의 변화가 일정이하인지를 판단한다(제3단계, S3).Subsequently, the ECU 1 determines whether the change in the opening degree of the throttle valve is less than or equal to the predetermined value by the signal from the throttle position sensor (third step, S3).

이는 운전자가 가속페달을 밟아 가속할려고 하고 있는지의 여부를 판단하기 위해서이다. 가속페달을 밟는 상태는 실제적으로 차량서지가 일어나는 데도 불구하고 엔진회전수가 증가한다. 따라서 운전자가 가속페달을 밟음으로 인하여 엔진회전수가 증가하는 경우에는 차량서지방지를 위한 점화제어가 행해지지 않고, 스로틀밸브의 개도변화량이 적은 상태, 즉 운전자가 가속페달을 밟지 않은 상태에서 엔진회전수의 증감이 있을 때 차량서지방지를 위한 점화제어가 행해지게 된다.This is to determine whether the driver is trying to accelerate by stepping on the accelerator pedal. Stepping on the accelerator pedal increases the engine speed despite the fact that the vehicle surge actually occurs. Therefore, when the engine speed increases due to the driver's stepping on the accelerator pedal, the ignition control for the vehicle's western region is not performed, and the engine speed is low when the throttle valve has a small amount of opening change, that is, the driver does not step on the accelerator pedal. When there is an increase or decrease of ignition, ignition control for the vehicle west region is performed.

그리고 ECU(1)는 차속센서로 부터의 신호에 의해서 차속이 일정이상인지를 판단한다(제4단계, S4).The ECU 1 then determines whether the vehicle speed is equal to or higher than a certain level by the signal from the vehicle speed sensor (step 4, S4).

공회전상태, 즉 저속인 상태에서는 엔진회전수의 증가이 있어도 실제적으로 차량서지가 일어나지 않는다. 따라서 공회전상태에서 엔진회전수의 증감이 있어도 차량서지를 방지하기 위해서 점화제어를 행할 필요가 없으므로 차속이 일정이상인지를 판단하는 것이다.In the idling state, that is, the low speed state, even if the engine speed increases, the vehicle surge does not actually occur. Therefore, even if there is an increase or decrease in the engine speed in the idle state, it is not necessary to perform the ignition control to prevent the vehicle surge, and thus it is determined whether the vehicle speed is a certain level or more.

그리고 상기와 같은 엔진회전수와 엔진부하의 조건이 만족되고, 스로틀밸브개도변화량과 차속의 조건이 만족되는 경우에 한하여 ECU(1)는 엔진회전수의 증가 있는지를 판단하여(제5단계,S5), 엔진회전수증가가 있을 때에는 점화시기를 리타드시킨다(제6단계, S6).The ECU 1 determines whether the engine speed is increased only when the conditions of the engine speed and the engine load as described above are satisfied and the conditions of the throttle valve opening amount and the vehicle speed are satisfied (step 5, S5). If the engine speed increases, the ignition timing is retarded (sixth step S6).

그리고 ECU(1)는 엔진회전수의 감소가 있는지를 판단하여(제7단계, S7), 엔진회전수감소가 있을 때에는 점화시기를 어드밴스시킨다(제8단계, S8).The ECU 1 judges whether or not the engine speed decreases (seventh step S7), and advances the ignition timing when the engine speed decreases (eighth step S8).

상기와 같이 본 발명의 차량서지방지를 위한 점화제어방법은 엔진회전수와 엔진부하가 차량서지가 발생할 조건을 만족하고 또한 스로틀밸브개도의 변화량이 많고 차속이 일정이상이 되는 경우에 한하여 차량서지 방지를 위하여 점화시기를 어드밴스 또는 리타드하도록 되어 있다.As described above, the ignition control method for the vehicle standing area of the present invention prevents vehicle surge only when the engine speed and the engine load satisfy a condition in which the vehicle surge occurs, and the amount of change in the throttle valve opening degree is large and the vehicle speed becomes a certain level or more. The ignition timing is advanced or retarded for this purpose.

본 발명의 차량서지방지를 위한 점화제어방법은 상기와 같이 실질적으로 차량서지가 일정나지 않는 공회전상태, 차속이 느린상태, 그리고 스로틀밸브개도의 변화량이 많은 상태, 즉 운전자가 가속페달을 밟는 상태에서는 차량서지방지를 위한 불필요한 점화제어를 하지 않기 때문에 운전성, 엔진출력, 연비등이 향상되는 효과를 발휘하게 된다.In the ignition control method for the vehicle surge region of the present invention, in the idle state, the vehicle speed is slow, and the amount of change in the throttle valve opening degree is substantially unchanged, that is, the driver steps on the accelerator pedal as described above. Since unnecessary ignition control is not performed for the vehicle west region, driving performance, engine power, fuel economy, etc. are improved.

본 발명은 기재된 구체예에 대해서만 상세히 설명되었지만 본 발명의 사상과 범주내에서 다양하게 변경 또는 수정할수 있음은 본 발명이 속하는 기술분야에서 통상의 지식을 가진자에게는 자명하다. 따라서 그러한 변경예나 수정예는 첨부한 본 발명의 특허청구범위에 속한다 해야 할 것이다.Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made within the spirit and scope of the present invention. Therefore, such changes or modifications will have to belong to the appended claims of the present invention.
