Title: Idle speed control device for internal combustion engine
Inventor: KUNIMASA AKIO
IPC: F02D41/16
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a control deviation of control of an ISC even when an external load is charged by a method wherein a plurality of correction control amounts are added to and subtracted from a fundamental air flow rate and based thereon, a control value is calculated, and based on a control value during idle an engine is controlled to the given target speed.

Based on the computing result of the control amount computing means, a control value is calculated by the control value calculating means of the ECU 51. Based on the control value, a control duty ratio is determined. Thus, when the control duty ratio of an idle speed control valve(ISCV) is corrected, a correction content forms an actually demanding air flow rate and to output a duty ratio from the air flow rate, correction control of a constantly demanding air flow rate is practicable, and unmatching of a control air flow rate based on non-linear characteristics which the ISCV has is solved.
