<P>PROBLEM TO BE SOLVED: To provide an internal combustion engine control device that further properly models an intake system of an engine having a throttle valve, and accurately calculates a control parameter related to an intake air amount by properly correcting a modeled error of the obtained model. <P>SOLUTION: A detection throttle valve opening degree is employed to a model type of a valve passing air flow rate which is obtained by modeling a relation between a throttle valve opening degree and a flow rate of air which passes the throttle valve, an estimate intake air flow rate is calculated, and modeled error coefficients KTHERR and KTHERRS which indicate modeled errors of the valve passing air flow rate model type are calculated by using an intake air flow rate to be detected. Model correction coefficients KMDLS and KMDLL are calculated by using the modeled error coefficients KTHERRS and KTHERR, the estimate intake air flow rate is corrected by using the model correction coefficients KMDLS and KMDLL, and the estimated estimate intake air flow rate is employed to the calculation of an engine control parameter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
