ENGINE SPEED CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To prevent the effect of a change with the lapse of time land individual difference on feedback control of revolutions. SOLUTION: In this control device, when the throttle opening correction amount DTHA(n) is more (less) than the predetermined specified amount KDTHA(-KDTHA) [Yes in a step 1006 (1007)], the predetermined shift amount dGTHA is subtracted (added) from (to) reference throttle opening GTHA(n) (step 1008 (1009)) to find next reference throttle opening GTHA(n+1) and next throttle opening correction value DTHA(n+1) is found by adding (subtracting) the shift amount dGTHA to (from) the throttle opening correction amount DTHA(n) (step 1010 (1011)). The next reference throttle opening GTHA(n+1) and the next throttle opening correction amount DTHA(n+1) are added to each other to find the next throttle opening THA(n+1) [step 1012].
