摘要： PROBLEM TO BE SOLVED: To provide idle speed control in an internal combustion engine for controlling an intake air quantity by two variable valve systems 5 and 6.
SOLUTION: A basic value of target throttle valve opening of an electronic control throttle valve and a basic value of a target operation angle and a target central angle of the variable valve systems, are set on the basis of accelerator opening APO and an engine speed Ne (B71). The target operation angle and the target throttle valve opening are corrected as feedforward control by an auxiliary machine load corresponding quantity (B74) by detecting the existence of an auxiliary machine load (B73) in idle operation (B72). A deviation between the target idle speed (B75) and an actual engine speed Ne is calculated (B76), and the target operation angle is corrected by making a feedback process in response to this deviation (B77). When calculating a correction quantity of the target operation angle, an actual central angle at this time is taken into consideration, and influence on an increase-decrease quantity of the intake air quantity by a central angle is eliminated, and controllability is stabilized.
