Description
본 발명은 차량 엔진 전자 제어 유니트(ECU)에 관한 것으로서, 특히 운전자가 간단한 스위치 조작만으로도 엔진의 출력을 향상 시킬 수 있도록 한 ECU 조절 모드 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle engine electronic control unit (ECU), and more particularly to an ECU control mode method that enables a driver to improve the output of the engine with a simple switch operation.
종래의 차량 엔진 구동은 엔진 ECU에 의해 이루어진다.Conventional vehicle engine driving is performed by an engine ECU.
상기한 엔진 ECU는 엔진 및 유입되는 공기량, 엔진회전수, 대기압, 유입되는 공기온도, 산소량등 기타 조건들을 감지 센서 에 의해 감지하여 배기가스 규정치를 준수하도록 최전화된 알고리즘에 따라 엔진에 유입되는 연료량을 조절하였다.The engine ECU detects the engine and the amount of inflow air, engine speed, atmospheric pressure, inflow air temperature, oxygen amount, etc. by a sensing sensor, and the amount of fuel flowing into the engine according to the algorithm that has been converted to comply with emission regulations. Was adjusted.
그러나 이러한 종래기술은 자동차 제조회사에서 엔진 ECU의 동작 알고리즘을 단일화로 고정시켜 차량을 출고하므로 운전자가 상황에 따라 적절하게 엔진 출력을 조절할 수가 없었고, 또는 엔진 출력을 향상 시키기 위해 별도로 터보 체인저(Turbo Charger)등 과급기를 부가 설치해야만 하므로 연비가 나빠지게 되는 문제점이 있었다.However, such a conventional technology is that a vehicle manufacturer releases a vehicle by fixing the operation algorithm of the engine ECU to a single unit, and thus, the driver cannot adjust the engine power according to the situation, or separately, to improve the engine power, a turbo charger (Turbo Charger) Since the supercharger must be installed additionally, there was a problem that the fuel economy becomes worse.
따라서 본 발명은 상기한 종래 기술의 문제점을 해소코자하여 제안된것으로서, 별도의 하드웨어 장치의 부가 설치 없이도 엔진 ECU의 동작 알고리즘을 개선 함으로써 차량의 엔진 출력을 향상 시킬수 있도록 한 차량 엔진 ECU 조절 모드 방법을 제공함을 그 목적으로 하는 것이다.Therefore, the present invention is proposed to solve the above problems of the prior art, a vehicle engine ECU control mode method to improve the engine output of the vehicle by improving the operation algorithm of the engine ECU without the installation of a separate hardware device The purpose is to provide.
이러한 목적을 달성하기 위한 본 발명의 기술적 방법은 스위치의 온,오프 상태를 판별하는 제1과정과, 상기 제1과정에서 스위치가 온(ON) 상태이면 A/R 값에서 최대 토오크값을 사용하고, 또한 산소량검출(O2) 센서의 출력값을 하향 조절하는 제2과정과, 스위치가 오프(OFF) 상태이면 A/R 값에서 최적의 배기 가스값을 사용하고, 또한 산소량검출(O2) 센서의 출력값을 그대로 적용하는 제3과정과, 상기 제2, 제3과정 이후 연료량을 결정하고 종료하는 제4 과정으로 이루어진 것이다.The technical method of the present invention for achieving this purpose is to use the first torque to determine the on, off state of the switch, and using the maximum torque value in the A / R value when the switch in the (on) state in the first process , and the oxygen content detected (O 2) a second step of down-regulation of the output of the sensors and, and when the switch is turned off (oFF) state in the a / R values using the optimum exhaust gas value, and the oxygen content detected (O 2) sensor The third step of applying the output value of as it is, and the second, after the third step and the fourth step of determining the amount of fuel after the end.
도 1은 에이/알(A/R) 값 설명도1 is an explanatory diagram of A / R values
도 2는 본 발명에 의한 ECU 조절 모드 동작 흐름도2 is a flowchart illustrating the operation of the ECU control mode according to the present invention.
이와같이 이루어진 본 발명의 동작 및 작용효과를 첨부된 도면에 의거하여 상술하면 다음과 같다.Referring to the operation and effect of the present invention made as described above based on the accompanying drawings as follows.
먼저 본 발명에 의한 엔진 ECU는 기존의 장치에 온,오프 스위치와 상기 스위치의 온,오프 상태를 감지하는 부가적인 회로를 구비하고 있다.First, the engine ECU according to the present invention includes an on / off switch and an additional circuit for detecting an on / off state of the switch in an existing device.
이러한 장치와 관련하여 본 발명 방법은 각 센서값중 유입공기량과 엔진회전수의 값(A/R값)을 산출한다.In connection with such an apparatus, the method calculates the value of the intake air amount and the engine speed (A / R value) among the sensor values.
상기한 A/R값은 각 엔진에 따라 실험에 의해 구해지며, 각 차량 메이커에서 엔진 ECU에 저장시켜 놓고, 이값을 기준으로 연료량을 결정한다.The A / R values are obtained by experiments for each engine, and are stored in the engine ECU at each vehicle manufacturer, and the amount of fuel is determined based on these values.
또한 A/R 데이터를 이용하여 배기가스를 규제하거나 최대 토오크를 발휘하도록 조절할 수가 있다.A / R data can also be used to regulate exhaust gas or adjust for maximum torque.
따라서 본 발명에서는 엔진 ECU의 알고리즘을 변경하여 엔진의 전체적인 성능 및 특성을 결정하게 된다.Therefore, in the present invention, the algorithm of the engine ECU is changed to determine the overall performance and characteristics of the engine.
즉, 도 1에 도시된 A/R도에서 스위치가 오프상태이면 도 2에 도시한 바와 같이 기존의 방식대로 A/R값에서 최적의 배기 가스값을 사용하고, 산소량 검출(O2) 센서 의 출력값을 그대로 적용하게 된다.That is, the in conventional manner using the optimum exhaust gas value in the A / R value, the oxygen content detected (O 2) sensor, as shown in the A / R 2 Fig. When the status is switched off in shown in Figure 1 The output value is applied as it is.
한편 스위치가 온 상태이면 A/R값에서 최대 토오크값을 사용하고, 산소량 검출(O2) 센서의 출력값(이득값)을 하향 조절하게 된다.On the other hand, when the switch is on, the maximum torque value is used in the A / R value, and the output value (gain value) of the oxygen amount detection (O 2 ) sensor is adjusted downward.
여기서 엔진의 출력을 보다 더 효과적으로 향상시키기 위해 스위치가 온 상태인 경우 상기한 산소량 검출(O2) 센서의 출력값을 동시에 조정하는 것이 바람직하다.In this case, in order to more effectively improve the output of the engine, when the switch is in the ON state, it is preferable to simultaneously adjust the output value of the oxygen amount detection (O 2 ) sensor.
즉, 배기가스중에 산소량이 많으면 공연비 14.6:1을 맞추기 위해 연료량을 줄이고 산소가 적으면 연료량을 늘리므로서 피드백 형태로 연료량을 조절하게 되는 것이다.That is, when the amount of oxygen in the exhaust gas is large, the amount of fuel is reduced to match the air-fuel ratio 14.6: 1, and when the amount of oxygen is low, the amount of oxygen is increased to adjust the amount of fuel in the form of feedback.
이상에서 설명한 바와 같이 본 발명은 별도의 하드웨어 장치의 부가 설치없이도 엔진 ECU의 동작 알고리즘을 개선함으로써, 차량의 엔진 출력을 향상시킬수 있고, 또한 터보 엔진 등에 비하여 필요한 경우에만 출력을 증가시키므로 연비가 좋을 뿐 아니라 출력 향상에 따른 배기 가스 오염이 문제시되는 경우 그의 작동시간을 제한 할 수 있는 효과가 있는 것이다.As described above, the present invention can improve the engine output of the vehicle by improving the operation algorithm of the engine ECU without additional installation of a hardware device, and increases fuel output only when necessary compared to a turbo engine. Rather, when exhaust gas contamination due to power output is a problem, it is possible to limit its operating time.
