Abstract

본 발명은 차량의 감속시 스로틀밸브의 급속한 차단을 방지하는 대시포트(dash pot)를 가진 상기 차량의 아이들 상태에서 적어도 차량의 엔진 속도에 기초하여 전자 제어기를 통해 아이들 상태를 제어하는 차량의 아이들 제어 방법에 있어서, 차량의 엔진 속도치와 상기 제어기 내 내장된 목표치간 차가 소정의 범위 내에 있는지 여부를 판단하는 단계; 판단단계에서 감속시 스로틀 밸브 오프에서 상기 대시 포트를 작동하여 공연비 및 흡입 혼합기량을 보정하는 단계; 판단단계에서 가속시 상기 스로틀 밸브 개도를 증가시켜 ISC유량을 제어하는 단계를 포함하며, 대시 포트량은 아이들 상태에서의 기본 유량보다 크게 설정된 것을 특징으로 하는 차량의 아이들 상태 제어 방법에 관한 것이다.The present invention provides an idle control of a vehicle that controls an idle state through an electronic controller based at least on the engine speed of the vehicle in an idle state of the vehicle with a dash pot that prevents rapid shutoff of the throttle valve upon deceleration of the vehicle. A method comprising: determining whether a difference between an engine speed value of a vehicle and a target value embedded in the controller is within a predetermined range; Correcting the air-fuel ratio and suction mixer amount by operating the dash port at the throttle valve-off when decelerating in the determining step; And controlling the ISC flow rate by increasing the opening degree of the throttle valve during acceleration in the determining step, wherein the dash pot amount is set to be larger than the basic flow rate in the idle state.
