Abstract

본 발명은 자동변속기를 장착한 차량에서 P단 또는 N단에서 구동단(R,D,L)으로의 기어 시프트시에 야기되는 엔진 RPM의 저하를 방지할 수 있도록 한 엔진 RPM보상 제어방법에 관한 것으로, 자동 변속기의 P단 또는 N단에서 구동단으로의 기어 시프트 신호 입력시에 설정된 소정시간 동안 실린더에 강제적으로 연료를 분사시키는 단계와, 강제적인 연료 분사에 의해 보상된 엔진 RPM과 냉각수온 신호에 기초하여 설정된 목표 RPM을 비교하는 단계와, 엔진 RPM과 목표 RPM의 비교결과 다를 경우 인젝터의 연료분사량을 증감시킴과 동시에 점화시기를 조절하여 엔진 RPM이 목표 RPM에 일치되도록 제어하는 단계에 의해, 기어 시프트시의 RPM저하를 보상해 주므로서, 엔진의 수명연장과 차량 사용의 편리성을 개선한 것이다.The present invention relates to an engine RPM compensation control method for preventing a decrease in engine RPM caused by a gear shift from a P stage or an N stage to a drive stage (R, D, L) in a vehicle equipped with an automatic transmission. Forcibly injecting fuel into the cylinder for a predetermined time set at the time of inputting the gear shift signal from the P stage or the N stage of the automatic transmission to the drive stage, and the engine RPM and cooling water temperature signals compensated by the forced fuel injection; Comparing the target RPM set based on the step, and controlling the engine RPM to match the target RPM by increasing and decreasing the fuel injection amount of the injector and adjusting the ignition timing when the comparison result of the engine RPM and the target RPM is different. By compensating for the reduction in RPM during gear shifts, the engine has a longer life span and improved usability.
