Description

에이/에프 그룹별 제어 장치A / F Group Control Unit

본 고안은 A/F(에이/에프) 그룹별 제어장치에 관한 것으로서, 특히 제어영역을다수의 영역으로 구분하고 트로틀 포지션 센서 전압이 4.5V 이상이면 무조건 WOT 영역으로 판정하여 균일하게 제어함으로써, WOT 영역 한 포인트의 제어값을 설정해 놓으면 엔진 회전수가 WOT 구간에 해당하는 영역에서의 A/F제어가 자동으로 이루어지도록 한 A/F 그룹별 제어장치에 관한 것이다.The present invention relates to a control device for each A / F group, and in particular, the control area is divided into a plurality of areas, and if the throttle position sensor voltage is 4.5V or higher, the WOT area is unconditionally determined and uniformly controlled. When the control value of one point of the area is set, the A / F group control device is configured to automatically perform A / F control in the area corresponding to the engine speed.

종래에는 A/F 제어시 엔진의 회전수마다 각각의 A/F 제어값을 셋팅하여야 했으므로, 제어가 정확하게 이루어지지 않았으며, 사용자가 일일이 제어값을 셋팅해야만 하는 번거로움이 발생하는 문제점이 있었다.In the related art, since the A / F control value had to be set for each rotational speed of the engine during A / F control, the control was not accurately performed, and there was a problem in that the user had to set the control value manually.

따라서, 상기 문제점을 해결하기 위한 본 고안은 제어영역을 다수의 영역으로 구분하고 트로틀 포지션 센서 전압이 4.5V 이상이면 무조건 WOT 영역으로 판정하여 균일하게 제어함으로써, WOT 영역 한 포인트의 제어값을 설정해 놓으면 엔진회전수가 WOT 구간에 해당하는 영역에서의 A/F제어가 자동으로 이루어지도록 한 A/F 그룹별 제어장치를 제공함을 목적으로 한다.Therefore, the present invention for solving the above problems is to divide the control area into a plurality of areas, and if the throttle position sensor voltage is 4.5V or higher, unconditionally determine the WOT area and control uniformly, so as to set the control value of one point of the WOT area. It is an object of the present invention to provide a control device for each A / F group in which the A / F control is automatically performed in an area corresponding to the engine speed.

이하, 상기 목적을 달성하기 위한 본 고안의 일실시예를 첨부된 도 1에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention for achieving the above object will be described in detail with reference to FIG. 1.

먼저, 본 고안의 A/F 그룹별 제어장치는 트로틀 밸브의 포지션을 감지하여 소정의 전압으로 변환 출력하는 트로틀 포지션 센서(1)와, 엔진(5)의 회전수를 감지하여 소정의 전압으로 변환 출력하는 엔진 회전수 센서(2)와, 사용자가 A/F 제어값을 셋팅할 수 있도록 하는 키이 입력부(3)와, 상기 각 센서(1)(2)로부터 입력되는 정보에 따라 엔진(5)의 A/F를 제어하는 A/F제어부(4)로 구성된다.First, the control device for each A / F group of the present invention detects the position of the throttle valve and converts it into a predetermined voltage, and detects the rotational position of the throttle position sensor 1 and the engine 5 and converts it into a predetermined voltage. The engine 5 according to the engine speed sensor 2 to output, the key input part 3 which allows a user to set A / F control value, and the information input from each said sensor 1 and 2. A / F control unit 4 for controlling the A / F of the.

상기와 같이 구성된 본 고안의 일실시예를 설명하면 다음과 같다.Referring to one embodiment of the present invention configured as described above are as follows.

먼저, 차량이 주행하면, 트로틀 포지션 센서(1)는 트로틀 밸브의 포지션을 감지하여 소정의 전압을 제어부(4)로 출력하고, 엔진 회전수 센서(2)는 엔진(5)의 회전수를 감지하여 제어부(4)로 출력한다.First, when the vehicle travels, the throttle position sensor 1 detects the position of the throttle valve and outputs a predetermined voltage to the controller 4, and the engine speed sensor 2 detects the rotation speed of the engine 5. To the control unit 4.

이때, 상기 제어부(4)는 트로틀 포지션 센서(1)와 엔진 회전수 센서(2)로부터 입력되는 신호에 따라 엔진(5)의 A/F 제어를 수행하게 되는데, 그 동작을 설명하면 다음과 같다.In this case, the controller 4 performs A / F control of the engine 5 according to the signals input from the throttle position sensor 1 and the engine speed sensor 2, and the operation thereof will be described as follows. .

제어부(4)는 엔진 회전수 센서(2)로부터 입력되는 신호로 엔진(5)의 회전수를 판단하고, 그 회전수 영역에 따라 A/F 제어를 실시한다.The control part 4 determines the rotation speed of the engine 5 by the signal input from the engine speed sensor 2, and performs A / F control according to the rotation speed area | region.

이때, 제어부(4)는 트로틀 포지션 센서(1)로부터 입력되는 신호의 전압이 4.5V를 넘게 되면 WOT영역으로 판정하고, 사용자가 키이 입력부(3)을 조작하여 설정해 놓은 A/F 제어값으로 엔진(5)을 제어한다.At this time, when the voltage of the signal input from the throttle position sensor 1 exceeds 4.5V, the control unit 4 determines the WOT area, and the engine operates with the A / F control value set by the user by operating the key input unit 3. (5) to control.

WOT 영역은 엔진 회전수가 1000~4000rpm 구가능로서, WOT 영역에서는 엔진회전수가 상기 범위내에서 가변되더라도 사용자가 설정해 놓은 제어값으로 엔진(5)의 A/F값을 제어하는 것이다.In the WOT area, the engine speed can be obtained from 1000 to 4000 rpm. In the WOT area, the A / F value of the engine 5 is controlled by a control value set by the user even if the engine speed varies within the above range.

즉, 사용자가 WOT 구간의 A/F 제어값을 설정해 놓으면, 그 다음부터는 이 영역의 A/F 제어를 별도로 수행하지 않아도 되는 이점이 있는 것이다.That is, if the user sets the A / F control value of the WOT section, there is an advantage that the A / F control of this area does not need to be performed afterwards.

이상에서 설명한 바와 같이 본 고안은 제어영역을 다수의 영역으로 구분하고 트로틀 포지션 센서 전압이 4.5V 이상이면 무조건 WOT 영역으로 판정하여 균일하게 제어함으로써, WOT 영역 한 포인트의 제어값을 설정해 놓으면 엔진회전수가 WOT 구간에 해당하는 영역에서의 A/F 제어가 자동으로 이루어지도록 한 A/F 그룹별 제어장치이다.As described above, the present invention divides the control area into a plurality of areas, and if the throttle position sensor voltage is 4.5V or more, unconditionally determines the WOT area and uniformly controls the engine speed by setting the control value of one point of the WOT area. It is a control device for each A / F group that automatically performs A / F control in the area corresponding to the WOT section.
