Abstract:
1. An apparatus for controlling an intake air amount of an internal combustion engine provided with a variable valve mechanism that varies at least a valve operating characteristic of an intake valve and provided with a throttle valve driven to open and close by an actuator, comprising: an operating condition detecting sensor detecting operating conditions of said engine; a valve operating characteristic detecting sensor detecting said valve operating characteristic; a control unit that sets a target intake air amount equivalent to a target torque according to the operating conditions of the engine, sets a target valve operating characteristic based on the set target intake air amount, and controls said variable valve mechanism so that an actual valve operating characteristic reaches said target valve operating characteristic; and a throttle opening sensor detecting an opening of said throttle valve, wherein said control unit sets a target throttle opening of said throttle valve based on said target intake air amount and said valve operating characteristic, to control said actuator so that an actual throttle opening reaches said target throttle opening.
