Abstract

PURPOSE: To precisely control the idling speed of an engine to a target level, by controlling the revolving speed in accordance with a difference between the target speed and an actual speed.
CONSTITUTION: An output representing a target revolving speed is produced in accordance with the temperature of engine cooling water from a function generating circuit 302 and also with the state of connection of a cooler as an engine load. A comparator 304 compares the target value with the actual revolving speed to put out a high or low level signal which is integrated by an integrating circuit 305. When the engine revolving speed exceeds the target level, an actuator 5 reduces bypass air flow to curb the revolving speed. The speed is also controlled in accordance with a compensating value compounded by load compensating data and temperature compensating data which is an output of learning control circuit 314.
