Abstract

본 발명은 차량의 아이들 상태 제어에 있어서, 연료량 보정에 의해서 엔진 rpm이 목표치에 접근하도록하여 공기량 제어 방식을 개선하도록 한 것으로, 차량의 아이들 상태에서 적어도 차량의 엔진 속도에 기초하여 전자제어기를 통해 아이들 상태를 제어하는 차량의 아이들 제어 방법에 있어서, 차량의 엔진 속도치와 상기 제어기내 내장된 목표치간 차가 소정의 범위내에 있는지 여부를 판단하는 단계; 차량의 엔진 속도치에 대한 필터링을 행하여 연료량 보정 이득치를 도출하는 단계; 기본 연료량과 상기 이득치와의 곱을 행하여 보정 연료량에 의해 엔진이 동작되는 단계; 보정 연료량에 의한 엔진 속도와 상기 목표치를 비교하여 상기 소정 범위 내에 있는지플 판단하여 상기 단계를 반복하는 단계로 이루어져 있다.The present invention is to improve the air volume control method by adjusting the fuel amount to approach the engine rpm in the idle state control of the vehicle, the idle state of the vehicle based on at least the engine speed of the vehicle through the electronic controller An idle control method of a vehicle for controlling a state, the 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; Filtering the engine speed value of the vehicle to derive a fuel amount correction gain value; Multiplying the basic fuel amount by the gain to operate the engine by the corrected fuel amount; And comparing the engine speed by the corrected fuel amount with the target value to determine whether the engine is within the predetermined range and repeating the above steps.
