Abstract
In a control apparatus of an internal combustion engine having an electronic throttle system driving an actuator so that a throttle valve provided in the internal combustion engine is at a target opening according to driving conditions, a throttle opening is turned to a limp home opening when abnormality is detected in the driving conditions so as to allow retreat traveling of a vehicle. The control apparatus of the internal combustion engine includes a brake operation detecting unit detecting a brake operation, in which when a brake operation is added subsequently while the accelerator pedal is operated, the control apparatus sets the target opening to the limp home opening based on occurrence of a sequence of the operations, and drives the actuator so that the throttle opening turns to the limp home opening, regardless of whether abnormality is detected or not.
