Abstract

PURPOSE:To prevent a delay of response in the transient state in acceleration/ deceleration mode, by detecting the acceleration/deceleration of an engine by switching an averaging circuit to a by-pass or to a smaller time constant only in the acceleration/deceleration mode. CONSTITUTION:In the acceleration mode Q of an engine, the air quantity signal (a) delivered from an inhaled air quantity meter 5 follows the acceleration of the engine to rise up suddenly. On the contrary, the output signal of an electronic averaging circuit 8 rises up gradually although the input signal has a sudden rise. Thus for a comparator 9 that compares the supplies the signal (a) and an averaged air quantity signal (b), the comparison signal (c) is changed from L to H at a time point T2 when the differential signal rises up to exceed the set value e+. As a result, a switch 10 is switched adversely to select the transmit the output signal of the unaveraged meter 5, i.e., the signal (a). In such a way, the signal (a) having high following properties is used as it is in the acceleration mode requiring high responsiveness. As a result, a delay of response can be prevented.
