Claim:
1. A control device for an internal combustion engine, comprising: an idle-stop control section for stopping fuel injection in response to generation of an automatic stop request to stop the internal combustion engine and restarting the internal combustion engine in response to generation of a restart request; an intake-air amount control section for setting a control amount of an intake system for controlling an intake air amount of the internal combustion engine so that the intake air amount becomes approximately zero when an intake-pipe pressure of the internal combustion engine at time of the generation of the automatic stop request is higher than a predetermined pressure and setting the control amount of the intake system so that the intake air amount becomes larger than the intake air amount at the time of the generation of the automatic stop request until the intake-pipe pressure becomes equal to the predetermined pressure and then the intake air amount becomes approximately zero when the intake-pipe pressure is lower than the predetermined pressure and; wherein the intake-pipe pressure comprises a value obtained by performing one of moving average processing and filtering processing on a measured intake-pipe pressure.
