Description

자동차 엔진의 점화 제어방법{Electronic Spark Adance Dwell Control Method For Engine Of Vehicles}Electronic Spark Adance Dwell Control Method For Engine Of Vehicles

본 발명은 자동차 엔진에 있어서, 스로틀 개도량과 변속단이 설정 기준치내에 있을 때, 점화시기의 지각량을 최소화하여 주행중 가속성을 향상시키고, 스로틀 개도량이 기준값 이상에서는 점화시기 지각 제어가 이루어지지 않도록 하여 등판능력을 향상시킬 수 있도록 한 자동차 엔진의 점화 제어방법에 관한 것이다.According to the present invention, when the throttle opening amount and the shift stage are within the set reference value, the perception amount of the ignition timing is minimized to improve acceleration during driving, and the throttle opening degree is not controlled when the throttle opening amount is higher than the reference value. The present invention relates to a ignition control method of an automobile engine to improve climbing capability.

일반적으로 자동차용 엔진은, 차량의 주행상태 및 주행조건에 따라 분사되는 연료량 및 흡기량과, 점화시기 등에 의하여 제어되며, 이런 제어과정은 운전조건에 따라 각 센서들로부터 검출되는 전기적인 신호를 엔진 제어를 위한 전자제어유닛 (ECU)에 미리 입력되어진 데이터와 비교 판단하여 소정의 로직에 따라 이루어지게 된다.In general, an automobile engine is controlled by the amount of fuel injected and the intake amount according to the driving condition and the driving conditions of the vehicle, the ignition timing, and the like. The control process controls the electric signals detected from the sensors according to the driving conditions. It is made according to a predetermined logic in comparison with the data previously input to the electronic control unit (ECU) for the.

이와같은 제어를 위한 엔진 제어 시스템은 엔진을 포함하는 차량의 적소에 배치된 각각의 센서들로부터 현재의 차량 운행 조건이 전기적인 신호로 검출되어 전자제어유닛(ECU, 이하 ECU로 칭함)으로 전달되면 ECU에서는 미리 설정되어 있는 제어로직에 따라 제어 구동부를 제어하여 현재 엔진 운전상태가 최적의 상태가 되도록 제어를 실시할 수 있도록 구성되어 있다.The engine control system for such a control, if the current vehicle operating conditions are detected as an electrical signal from each of the sensors disposed in place of the vehicle including the engine and transmitted to the electronic control unit (ECU, hereinafter referred to as ECU) The ECU is configured to control the control driver according to the control logic set in advance so that the control can be performed so that the current engine operating state is optimal.

이러한 일예로서, 종래의 점화 제어과정을 살펴보면, 도 3에서와 같이, 엔진이 시동된 상태에서(S300) 엔진 rpm이 기준값 범위 이내인가와, 차속이 기준값 이상이고, 냉각수온이 기준값 보다 큰가를 판단하여(S310)하여 그 조건이 만족하면, 현재 기어 변속단이 전진 변속단 위치인가를 판단하게 된다(S320).As one example, referring to the conventional ignition control process, as shown in FIG. 3, it is determined whether the engine rpm is within the reference value range, the vehicle speed is greater than the reference value, and the cooling water temperature is greater than the reference value as shown in FIG. 3. If the condition is satisfied (S310), it is determined whether the current gear shift stage is the forward shift stage position (S320).

상기 S320 단계에서 조건을 만족하면, 앤티 - 져크 펑션(Anti - Jerk Function)을 적용하고(S330) 완료하게 된다.If the condition is satisfied in step S320, the anti-jerk function is applied (S330) and is completed.

상기에서 앤티 - 져크 펑션(Anti - Jerk Function)은 운전자가 갑자기 가속을 위하여 가속페달을 심하게 밟는 경우, 급작스런 가속으로 차체의 심한 진동과 충격이 발생되는 것을 방지하기 위하여 점화 제어시기를 지각 제어함으로써, 차량이 유연하게 가속될 수 있도록 하는 기능이다.Anti-Jerk function (Anti-Jerk function), when the driver suddenly presses the accelerator pedal to accelerate suddenly, by perceptually controlling the ignition control timing in order to prevent the severe vibration and impact of the body due to sudden acceleration, This feature allows the vehicle to accelerate flexibly.

그러나 상기와 같은 제어방법에 차체의 진동이나 충격이 유연하게 가속이 이루어질 수 있다는 이론적인 효과는 있으나, 구배가 심한 도로 및 평지등이 구별되지 않고 전 변속단에서 일률적으로 점화시기 지각 제어가 과도하게 이루어져 구배가 십함 도로에서는 등판 능력이 저하되고, 평지에서는 주행중 가속시 가속감이 부족현상이 발생된다는 문제점을 내포하고 있다.However, there is a theoretical effect that the vibration and shock of the vehicle body can be flexibly accelerated by the control method as described above, but the road and the level of the gradient are not distinguished and the perception control of the ignition timing is excessively uniform at all shift stages. As a result of the gradient, the climbing ability is reduced on the road, and the lack of acceleration occurs during acceleration on the flat land.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 스로틀 개도량과 변속단이 설정 기준치내에 있을 때, 점화시기의 지각량을 최소화하여 주행중 가속성을 향상시키고, 스로틀 개도량이 기준값 이상에서는 점화시기 지각 제어가 이루어지지 않도록 하여 등판능력을 향상시킬 수 있도록 한 자동차 엔진의 점화 제어방법을 제공함에 있다.Therefore, the present invention has been invented to solve the above problems, an object of the present invention is to minimize the amount of ignition timing perception when the throttle opening amount and the shift stage is within the set reference value, to improve the acceleration during driving, throttle opening degree The present invention provides a method of controlling the ignition of an automobile engine to improve the climbing ability by preventing the ignition timing perception control above the reference value.

이를 실현하기 위하여 본 발명은, 엔진이 시동된 상태에서, 현재의 엔진 rpm이 일정 범위내인가를 판단함과 동시에 현재의 차속이 기준값 이상인가를 판단하는 제1 단계와;In order to realize this, the present invention includes a first step of judging whether the current engine rpm is within a predetermined range while the engine is started, and determining whether the current vehicle speed is equal to or greater than a reference value;

상기 제 3단계에서 스로틀 개도량이 기준값 이하라고 판단되면, 앤티 져크 펑션을 적용하되, 점화계통의 지각량을 최소화한 상태로 제어하고, 상기 제 3단계에서 스로틀 개도량이 기준값 이상이라고 판단되면, 앤티 져크 펑션을 미적용하는 제4단계로 이루어지는 자동차 엔진의 점화 제어방법을 제공한다.If the throttle opening amount is determined to be less than or equal to the reference value in the third step, the anti-jerk function is applied, but the control is performed to minimize the perception of the ignition system, and if the throttle opening amount is greater than or equal to the reference value in the third step, the anti-jerk Provided is a ignition control method for an automobile engine comprising a fourth step of not applying a function.

이하, 상기의 목적을 구체적으로 실현할 수 있는 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described in detail.

도 1은 본 발명에 관계하는 제어계통의 구성도로서, 본 발명의 제어계통은 엔진 및 차량의 운전상태를 검출하는 감지수단과, 상기 감지수단으로부터 입력되는 전기적인 신호를 미리 입력되어진 데이터와 비교하여 출력하는 전자제어유닛(ECU)와, 상기 전자제어유닛으로부터 출력되는 신호에 따라 구동되는 구동수단으로 이루어진다.1 is a configuration diagram of a control system according to the present invention, wherein the control system of the present invention compares sensing means for detecting a driving state of an engine and a vehicle, and electrical signals inputted from the sensing means with previously input data. And an electronic control unit (ECU) for outputting and driving means driven according to a signal output from the electronic control unit.

상기에서 감지수단으로는 엔진의 회전수를 검출하는 엔진 rpm 센서(2)와, 차속을 검출하는 차속센서(4)와, 냉각수온을 검출하는 냉각수온 센서(6)와, 스로틀 포지션 센서(8)와, 기어 변속단 검출센서(10)로 이루어지는데, 이의 감지수단은 이에 한정되는 것이 아니라, 본 발명을 운용하는데 최소한으로 필요한 감지수단의 구성요소만을 설명하고 있다.The sensing means includes an engine rpm sensor 2 for detecting the rotational speed of the engine, a vehicle speed sensor 4 for detecting the vehicle speed, a cooling water temperature sensor 6 for detecting the coolant temperature, and a throttle position sensor 8 ), And the gear shift stage detecting sensor 10, but the sensing means is not limited thereto, and only the components of the sensing means necessary for operating the present invention are described.

그리고 상기 감지수단으로부터 입력되는 전기적인 신호에 따라 전자제어유닛 (ECU)에서는 구동수단으로 엔진의 압축 혼합기의 연소를 유도하는 점화계통(12)을 제어하게 되는 것이다.In addition, the electronic control unit (ECU) controls the ignition system 12 which induces combustion of the compression mixer of the engine by the driving means according to the electric signal input from the sensing means.

상기와 같은 제어계통을 제어할 수 있는 본 발명의 작동 흐름을 살펴보면, 도 2에서와 같이, 엔진이 시동된 상태에서(S100), 현재의 엔진 rpm이 일정범위내인가를 판단(S110)함과 동시에 현재의 차속이 기준값 이상인가를 판단하게 된다 (S120).Looking at the operating flow of the present invention that can control the control system as described above, as shown in Figure 2, in the engine start state (S100), it is determined whether the current engine rpm is within a certain range (S110) and At the same time, it is determined whether the current vehicle speed is greater than or equal to the reference value (S120).

그리고 상기 S110 단계와 S120 단계에서 적어도 어느 하나의 조건을 만족하면, 현재의 냉각수온이 일정 범위내인가를 판단하게 되는데(S130), 이는 종래와는 달리 냉각수온에 따른 구간을 나누어 문제가 되는 부분에 앤티-져크 펑션의 적용을줄이기 위한 것이다.If at least one of the conditions is satisfied in steps S110 and S120, it is determined whether the current cooling water temperature is within a predetermined range (S130). This is to reduce the application of anti-jerk functions.

상기 S130 단계에서 냉각수온이 일정 범위내에 있다고 판단되면, 현재 변속기의 기어단수가 전진 1 내지 3단으로 변속되어 있는 상태를 판단하게 되며(S140), 이는 엔티-져크 펑션이 고속 변속단인 4속 및 5속에서는 적용되지 않도록 하여 가속감 및 등판능력을 향상시키기 위함이다.If it is determined in step S130 that the cooling water temperature is within a predetermined range, it is determined that the gear stage of the current transmission is shifted to the first to third gears (S140), which means that the anti-jerk function is the fourth speed of the high speed gear stage. In order to improve the feeling of acceleration and climbing ability by not being applied at 5 and 5 speed.

상기 S140 단계에서 변속단이 1 내지 3단내에 있다고 판단되면, 현재의 스로틀 개도량이 기준값 이하인가와 이상인가를 판단하게 된다(S160)(S170).If it is determined in step S140 that the shift stage is within one to three steps, it is determined whether the current throttle opening amount is equal to or less than the reference value (S160) (S170).

여기서 스로틀 개도량이 기준값 이하인가와 이상인가를 검출하는 것은 스로틀 개도량의 기준값을 설정하여 도로의 조건에 따라 가속감 또는 등판 성능을 향상시키는 역할을 수행하기 위함이다.The purpose of detecting whether the throttle opening amount is lower than or equal to the reference value is to set a reference value of the throttle opening amount to improve acceleration or climbing performance according to road conditions.

그리고 상기 S160 단계에서 스로틀 개도량이 기준값 이하라고 판단되면, 앤티 져크 펑션을 적용하되, 점화계통을 rpm의 변동에 따라 지각량을 줄여 제어함으로써(S180), 주행중 가속감 부족을 개선할 수 있게 된다.When the throttle opening amount is determined to be equal to or less than the reference value in step S160, the anti-jerk function is applied, and the ignition system is controlled by reducing the amount of perception according to the change in rpm (S180), thereby improving the lack of acceleration during driving.

또한, 상기 S170 단계에서 스로틀 개도량이 기준값 이상이라고 판단되면, 앤티 져크 펑션을 미적용하지 않음으로써(S190), 구배가 심한 도로에서 rpm 변동에 따른 점화계통의 지각 제어가 이루어지지 않아 등판 성능을 향상시킬 수 있게 되는 것이다.In addition, if the throttle opening amount is determined to be equal to or greater than the reference value in step S170, by not applying the antijerk function (S190), the perception control of the ignition system due to the rpm fluctuation is not made in a severe road, thereby improving climbing performance. It will be possible.

상기에서 rpm, 차속, 냉각수온, 스로틀 개도량의 기준은 적용차량 마다 다르게 설정되기 때문에 일정값으로 한정하지 않는다.In the above, the criteria of rpm, vehicle speed, cooling water temperature, and throttle opening amount are not limited to a predetermined value because they are set differently for each applied vehicle.

이상에서와 같이 본 발명에 의하면, 스로틀 개도량과 변속단이 설정 기준치내에 있을 때, 점화시기의 지각량을 최소화하여 주행중 가속성을 향상시키고, 스로틀 개도량이 기준값 이상에서는 점화시기 지각 제어가 이루어지지 않도록 하여 등판능력을 향상시킬 수 있는 발명인 것이다.As described above, according to the present invention, when the throttle opening amount and the shift stage are within the set reference value, the perception amount of the ignition timing is minimized to improve acceleration during driving, and the throttle opening degree is not controlled when the throttle opening amount is higher than the reference value. It is an invention that can improve the climbing ability.
