Abstract

과도보정의 허가조건(개시조건)을 적절한 것으로 한다.The conditions for permitting transient compensation (starting conditions) shall be appropriate.

스타트 스위치가 오프냐 아니냐를 판정하고(S31), 스타트 스위치가 오프인 경우에는 아이들 스위치가 온이냐 아니냐를 판정하고(S32), 아이들 스위치가 온인 경우에 온 이력 플래그 F=1에 세트한다(S33). 그리고, 아이들 스위치 오프인 경우에는 온 이력 플래그 F를 판정하고 (S34) F=1인 경우에 과동보정을 허가한다(S35). 즉, 스타트 스위치의 오프후에 아이들 스위치가 온→오프로 된 시점에서, 과도보정을 허가하여, 스로틀 밸브 개방도에 변화량에 따른 연료분사량의 가속증량, 감속증량보정을 진행시킨다.It is determined whether the start switch is off (S31). When the start switch is off, it is determined whether the idle switch is on (S32), and when the idle switch is on, the on history flag F = 1 is set (S33). ). In the case of the idle switch off, the on-history flag F is determined (S34). In the case of F = 1, overcorrection is permitted (S35). In other words, when the idle switch is turned on and off after the start switch is turned off, the over-correction is allowed, and the acceleration increase and deceleration increase correction of the fuel injection amount in accordance with the change amount in the throttle valve opening degree are advanced.
