Abstract

엔진의 동작 상태를 이용하여 아이들 피드백 제어가 실행될 수 있도록 하므로 엔진의 동작 상태에 따른 적절한 아이들 제어가 실행될 수 있도록 하는 엔진 회전수를 이용한 아이들 피드백 제어장치 및 그 방법을 제공하기 위하여, 엔진의 회전수에 따라 출력되는 전기 신호의 상태가 변화하는 엔진의 회전수 감지 수단과; 상기 엔진 회전수 감지 수단에서 출력되는 전기 신호를 이용하여 엔진의 회전수를 판정하고, 판정된 엔진의 회전수가 아이들 목표 회전수와 같을 경우 곧바로 아이들 목표 회전수를 유지할 수 있도록 하는 아이들 피드백 제어 동작을 실행하기 위한 제어 신호를 출력하는 엔진 제어 수단과; 상기 엔진 제어 수단에서 출력되는 제어 신호에 따라 동작 상태가 변화하여 아이들 피드백 제어를 위한 바이패스의 개도 상태를 보정하는 아이들 조정장치를 포함하여 이루어져 있다.In order to provide an idle feedback control apparatus and a method thereof using an engine rotational speed so that an idle feedback control can be executed using an operating state of the engine, so that an appropriate idle control according to the operating state of the engine can be executed. Engine speed detection means for changing the state of the electrical signal output according to; The engine speed is determined using the electrical signal output from the engine speed detecting means, and when the determined engine speed is equal to the idle target speed, an idle feedback control operation is performed to maintain the idle target speed immediately. Engine control means for outputting a control signal for execution; And an idle adjustment device configured to correct an opening state of the bypass for idle feedback control by changing an operation state according to a control signal output from the engine control means.
