Abstract
Description
Claims (1)
- 엔진 쇼크 및 저크를 개선하기 위한 방법에 있어서, 엔진이 아이들 상태인가를 판단하는 단계, 아이들 상태가 아닐 경우 드로틀 개도가 제1설정값보다 큰가를 판단하는 단계, 드로틀 개도가 제1설정값보다 큰 경우 엔진부하가 제2설정값보다 큰가를 판단하는 단계, 엔진부하가 제2설정값보다 큰 경우 RPM이 제3설정값과 제4설정값의 사이에 있는 가를 판단하는 단계, RPM이 제3설정값과 제4설정값의 사이에 있게 되는 경우 |RPM변동|이 제5설정값보다 큰가를 판단하는 단계, 및 |RPM변동|이 제5설정값보다 큰 경우 점화시기를 보정하는 단계로 구성되고; 점화시기를 보정하는 상기 단계에서 행하여지는 점화진각/지각값은, RPM변동 = (실RPM2-실RPM2-1) 식에 의해 RPM 변동값을 구하고, G를 게인값이라 할 때 필터링RPM2= 필터링RPM2-1+G(실RPM2-필터링RPM2-1) 식에 의해 필터링 RPM값을 구하고, G를 게인값이라 할 때 필터링RPM변동 = RPM변동2-1+G(RPM변동2-필터링RPM변동2-1) 식에 의해 필터링RPM변동값을 구하고, f(RPM)을 RPM에 따른 함수값이라 할 때 점화진각/지각값 = [f(RPM)×필터링RPM변동] 식에 의해 얻어지게 되는 것을 특징으로 하는 엔진 쇼크 및 저크를 개선하기 위한 방법.
