Description

The present invention relates to a fuel control system according to a driving mode that can increase customer satisfaction.
차량용 가솔린 엔진의 연료분사는 전자 제어식 시스템을 채용하고 있으며, 흡기 매니폴드에 분사하는 형식이 주로 사용되고 있다. 이러한 연료분사의 근본 원리는 연료계통에 항상 일정한 압력을 가해 두었다가 솔레노이드 밸브(즉, 인젝터)를 열어 주어 흡기 매니폴드 내에 연료를 분출시키는 구조를 갖고 있다.The fuel injection of the vehicle gasoline engine employs an electronically controlled system, and a type of injection into the intake manifold is mainly used. The basic principle of the fuel injection is to always apply a constant pressure to the fuel system and open the solenoid valve (ie, the injector) to eject the fuel into the intake manifold.
이러한 전자식 연료분사의 제어는 각종 주행상태에서 기관의 출력성능 향상과 연비 향상 및 공해 가스 저감 등을 실현하기 위한 것으로, 이를 위해 엔진의 냉각수 온도, 흡입공기의 온도, 흡기 매니폴드의 압력과 대기 압력, 차속, 스로틀 개도량, 크랭크 각 신호 등을 각종 센서를 사용하여 검출한 후 이에 기초하여 마이크로컴퓨터에서 에어콘 릴레이, 연료펌프 릴레이, 인젝터, 점화코일, ISC 밸브 등을 제어하고 있다.The control of the electronic fuel injection is to realize the engine's output performance, fuel economy and pollution gas reduction under various driving conditions.For this purpose, the engine's coolant temperature, intake air temperature, intake manifold pressure and atmospheric pressure After detecting the vehicle speed, the throttle opening amount, the crank angle signal, and the like using various sensors, the microcomputer controls the air conditioner relay, fuel pump relay, injector, ignition coil, and ISC valve.
상기한 컴퓨터에 의한 제어를 크게 나누면 분사시기에 제어와 분사량 제어로 나눈다. 먼저 분사시기 제어는 점화코일의 점화신호를 사용하며, 분사량 제어는 점화코일의 점화신호와 흡입 공기량 신호에 의한 기본 분사시간을 만듦과 동시에 각 센서로부터의 검출신호에 의해 분사시간의 보정을 행하여 인젝터를 작동시키는 최종적인 분사시간을 정하고 있다.The control by the computer is largely divided into control and injection amount control at the time of injection. First, the injection timing control uses the ignition signal of the ignition coil, and the injection amount control creates the basic injection time by the ignition signal and the intake air amount signal of the ignition coil, and simultaneously corrects the injection time by the detection signal from each sensor. Final injection time is set to operate.
상기한 연료분사는 엔진 1회전마다 1회의 분사가 이루어지며, 분사의 시기는 점화와 동기해서 이루어지므로 4기통의 경우에는 점화 2회에 대하여 1회, 6기통의 경우는 점화 3회에 대하여 1회의 비율로 분사한다.The above fuel injection is carried out once per engine revolution, and the timing of injection is made in synchronization with the ignition. Therefore, once for four cylinders, one for two ignitions and one for six cylinders, one for three ignitions. Participating at the meeting rate.
한편 분사량 제어는 점화코일의 신호를 기초로 회전수의 신호를 만들어 이 신호와 흡입공기량 싱호에 의해 기본 분사신호를 만든다. 그 후 컴퓨터는 시동/난기에 따른 중량, 흡기온 보정, 스로틀 포지션 센서(TPS)에 의한 스로틀 개도량의 변화, 즉, 출력 증가에 따른 증량, 밧데리 전압레벨에 따른 전압보정, MAP 센서에 의해 검출된 흡입 공기량 변화에 따른 보정 등의 보정을 행하여 인젝터 구동용 최종분자시간을 구한다.On the other hand, the injection rate control generates a signal of the rotation speed based on the signal of the ignition coil, and generates a basic injection signal by this signal and the intake air amount signal. Then, the computer detects the weight according to the start / warm, the intake temperature correction, the change in the throttle opening amount by the throttle position sensor (TPS), that is, the increase according to the increase in output, the voltage correction according to the battery voltage level, and the MAP sensor. The final molecular time for driving the injector is obtained by correcting the correction according to the change of the intake air amount.
그런데 상기한 연료 분사량의 제어는 각각의 센서로부터 검출된 신호에 기초하여 차량의 제조회사에서 미리 결정한 조건에 따라 이루어지고 있고, 운전자의 취향에 따라 주행모드를 선택하여 분사량을 제어할 수 있는 기능이 마련되어 있지 않다. 종래에는 변속레버를 이용한 엔진 출력의 제어와 전자제어 현가장치을 이용한 승차감의 개선과 주행 안정성의 도모가 이루어지고 있으며, 모든 변속단에서의 사용자 취향에 따른 모드 선택은 이루어질 수 없었다.However, the control of the fuel injection amount is performed according to a condition predetermined by the manufacturer of the vehicle based on the signal detected from each sensor, and the function of controlling the injection amount by selecting the driving mode according to the driver's preference is provided. It is not prepared. Conventionally, the control of the engine output using the shift lever and the improvement of the riding comfort and the driving stability using the electronically controlled suspension device have been made, and the mode selection according to the user's taste in all the shift stages cannot be made.
따라서 본 발명은 이러한 종래 기술의 문제점을 감안하여 안출된 것으로, 그 목적은 일반 주행, 연료 소모량의 경제성, 차량의 가속성, 주행상태의 안락함 등 운전자의 취향에 따라 주행모드를 선택하여 엔진의 연료 분사량을 제어함에 의해 소비자에 대한 만족도를 높일 수 이쓴 주행모드에 따른 연료 제어시스템을 제공하는데 있다.Accordingly, the present invention has been made in view of the problems of the prior art, and its purpose is to select the driving mode according to the driver's preference such as general driving, economy of fuel consumption, acceleration of the vehicle, comfort of driving state, etc. It is to provide a fuel control system according to the driving mode that can increase the customer satisfaction by controlling the.
