Abstract
There is provided an internal combustion engine control apparatus that is capable of determining accurately from an ignition discharging time period whether the intake valve and the exhaust valve are in the operative condition or in the inoperative condition. A cylinder deactivation controller causes a first ignition controller to perform a first ignition control on the basis of the ignition timing when issuing no cylinder deactivation request, and causes a second ignition controller to perform a second ignition control on the basis of an energizing time period when issuing the cylinder deactivation controller. The discharging time period is calculated by a discharging time period calculation section on the basis of an ion current signal output from the ignition coil.
