Abstract

PURPOSE: To perform proper idle control by normally performing the open loop control on the idle rotary speed in accordance with a target setting circuit while temporarily performing the closed loop control by a trigger signal from a predetermined interval or operational condition detecting circuit.
CONSTITUTION: A target level or a control pulse signal is normally applied on a step motor 14 to perform the open loop control. While a differential circuit 17 will compare between the detected engine rotary speed and the target step number of the step motor 14 to produce the difference, and a gate 16 will temporarily apply the differential signal from the differential circuit 17 onto the control circuit 15 by a trigger signal from a frequency dividing circuit 21 to increase/decrease the target step number in a register of the control circuit 15. When using an air conditioner or when operating a power steering, a target setting circuit 20 for setting the target step number of the step motor 14 corresponding with said condition will operate.
