Abstract

내연기관의 EGR등의 유무전환시의 토크변화를 원활히 한다.Smooth the torque change during the presence or absence of EGR of internal combustion engine.

EGR지령이 출력되어 EGR 밸브 개방도를 제진기 계수 EGRDMP에 의거 서서히 증대시키는 제어가 개시되고 나서 지연시간 후에 일차 늦게 변화하는 흡기상태 변화비율 EGRDMP를 산출하고, 이 EGRDMP와 비례적으로 설정한 점화시기 연결 보정량에 의해 점화시기를 전환후의 목표치로 원활하게 이어지도록 설정한다.After the EGR command is output and the control to gradually increase the EGR valve opening degree based on the vibration suppressor coefficient EGRDMP is started, the intake state change rate EGRDMP, which changes first after a delay time, is calculated. The ignition timing is set to smoothly continue to the target value after switching by the correction amount.
