Description
본 고안은 아이들 스피드 제어 장치에 관한 것으로서, 보다 상세하게는 직류모터를 이용하여 스로틀 밸브가 항상 일정 정도 개방되도록 하여 아이들 스피드를 제어하는 장치에 관한 것이다.The present invention relates to an idle speed control device, and more particularly, to a device for controlling idle speed by allowing a throttle valve to always be opened to a certain degree using a DC motor.
일반적으로 아이들 스피드 제어 장치는 운전자가 가속 페달을 밟지 않은 상태에서는 스로틀 밸브가 닫힌 상태이므로 엔진이 무부하 상태로 기본적인 기계 작동이 가능하도록 하는 아이들 상태를 유지하기 위한 것이다.In general, the idle speed control device is to maintain the idle state to enable the basic mechanical operation without the engine load because the throttle valve is closed when the driver does not press the accelerator pedal.
즉, 엔진의 아이들 회전수를 유지시키기 위해 흡기 매니폴드로 적당량의 공기를 공급하도록 하는 것으로서, 엔진의 냉시동시와, 에어컨 스위치의 동작이나 감속시와 같이 급격한 엔진의 부하 변화에 대하여 흡입 공기량을 보정하여 엔진의 정숙한 운전이 가능하도록 하는 것이다.That is, in order to maintain the idle speed of the engine, an adequate amount of air is supplied to the intake manifold, and the intake air amount is corrected against sudden changes in the load of the engine such as during cold start of the engine and operation or deceleration of the air conditioner switch. It is to enable the quiet operation of the engine.
상기 아이들 스피드 제어 장치는 전자 제어 방식의 경우 도 1에 도시된 바와 같이 ECU(51)의 제어를 받는 아이들 스피드 액츄에이터(52)가 스로틀 밸브(53)를 바이패스시키는 공기의 유로(54)를 제어할 수 있도록 설치되어 있다.In the case of the electronic speed control method, the idle speed control device controls the air flow path 54 through which the idle speed actuator 52 controlled by the ECU 51 bypasses the throttle valve 53, as shown in FIG. 1. It is installed to do this.
즉, 상기 ECU(51)는 엔진의 rpm을 감지하여 상기 엔진의 rpm에 따라 상기 아이들 스피드 액츄에이터(52)를 제어하여 엔진으로 공급되는 공기량을 제어하도록 되어 있다.That is, the ECU 51 senses the rpm of the engine and controls the idle speed actuator 52 according to the rpm of the engine to control the amount of air supplied to the engine.
그러나, 상기한 아이들 스피드 제어 장치는 고가의 아이들 스피드 액츄에이터를 장착하여야 하고, 외부 공기가 통과하는 별도의 유로를 마련하여야 하므로 구성이 복잡하고 제품의 원가가 상승하게 되는 문제점이 있다.However, since the idle speed control device has to be equipped with an expensive idle speed actuator and a separate flow path through which external air passes, there is a problem in that the configuration is complicated and the cost of the product increases.
따라서, 본 고안은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 스로틀 밸브가 항상 일정 정도는 개방되도록 하여 운전자가 가속 페달을 밟지 않아도 엔진의 아이들 운전이 가능하도록 한 아이들 스피드 제어 장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, to provide an idle speed control device that allows the throttle valve is always opened to a certain degree to enable the idle operation of the engine without the driver stepping on the accelerator pedal. The purpose is.

상기한 바와 같은 목적을 달성하기 위한 본 고안에 따른 아이들 스피드 제어 장치는 회전하면서 스로틀 밸브를 개폐시키는 직류모터와, 엔진의 rpm을 입력받아 상기 직류모터를 구동하는 ECU로 구성된 것을 특징으로 한다.The idle speed control device according to the present invention for achieving the above object is characterized in that it consists of a DC motor for opening and closing the throttle valve while rotating, and an ECU for driving the DC motor by receiving the rpm of the engine.
이하, 첨부된 도면을 참조하여 본 고안의 실시예를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.
도 2는 본 고안에 따른 아이들 스피드 제어 장치가 도시되어 있는 바, 회전하면서 스로틀 밸브(1)를 개폐시키는 직류모터(2)와, 엔진의 rpm을 입력받아 상기 직류모터(2)를 구동하는 EUC(3)로 구성된다.Figure 2 shows an idle speed control device according to the present invention, the DC motor (2) for opening and closing the throttle valve (1) while rotating, the EUC to receive the rpm of the engine to drive the DC motor (2) It consists of (3).
상기와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
엔진이 아이들 운전을 할 때, ECU(3)는 상기 엔진의 rpm을 감지하여 직류모터(2)를 구동한다.When the engine drives idle, the ECU 3 senses the rpm of the engine and drives the DC motor 2.
즉, 상기 엔진의 rpm이 아이들 rpm보다 크면 상기 ECU(3)는 직류모터(2)를 구동하여 스로틀 밸브(1)가 일정 정도 개방되도록 제어하고, 상기 엔진의 rpm이 아이들 rpm보다 작으면 상기 ECU(3)는 상기 직류모터(2)를 구동하여 스로틀 밸브(1)가 닫히도록 제어한다.That is, when the rpm of the engine is greater than the idle rpm, the ECU 3 drives the DC motor 2 to control the throttle valve 1 to be opened to some extent, and when the rpm of the engine is smaller than the idle rpm, the ECU (3) controls the throttle valve (1) to close by driving the DC motor (2).
그러나, 운전자가 가속 페달을 밟으면 ECU(3)는 이를 감지하고 직류모터(2)의 구동을 정지시키는 바, 상기 가속 페달에 의해 스로틀 밸브(1)가 개폐되도록 한다.However, when the driver presses the accelerator pedal, the ECU 3 senses this and stops the driving of the DC motor 2, thereby allowing the throttle valve 1 to be opened and closed by the accelerator pedal.
이상과 같이, 본 고안은 스로틀 밸브가 가속 페달의 조작력에 의해 회전하도록 함과 아울러 직류모터에 의해 회전하도록 함으로써, 별도의 아이들 스피드 액츄에이터와 유로없이도 아이들 스피드 제어가 가능하여 제품의 가격이 절감되는 효과가 있다.As described above, the present invention allows the throttle valve to rotate by the operating force of the accelerator pedal and the DC motor to rotate, thereby enabling idle speed control without a separate idle speed actuator and a flow path, thereby reducing the price of the product. There is.
