PURPOSE:To prevent erroneous correction on the basis of erroneous decision of acceleration/deceleration, by providing means for stopping the function of an acceleration/deceleration correcting means for predetermined time after correction. CONSTITUTION:A deceleration timer 18 for stopping the correcting function is provided in an acceleration correcting circuit 14 and set through the correcting operation of a deceleration correcting circuit 15, thereby upon completion of decelerating correction counting is started to stop the function of said circuit 14 for predetermined time. While an acceleration timer 19 for stopping the correcting function is provided in said circuit 15, and upon completion of accelerating correction the function of said circuit 15 is stopped for predetermined time. Consequently even if there is erroneous decision of acceleration/deceleration due to overshoot of the output signal U/ub from an air flow meter 12, correction based on erroneous is decision is prevented. |
