Abstract: A control device includes target temperature setting means, feedback control means, and shortcut control means. The target temperature setting means sets a target temperature (?) of a coolant according to a temperature state of an internal combustion engine. The feedback control means controls a control valve in such a manner that a coolant temperature is the target temperature (?). The shortcut control means controls the control valve in such a manner that, when the internal combustion engine is in a cold state, the target temperature setting means sets as the target temperature (?) a warming-up temperature (?) higher than a feedback control temperature (A or B) which is set during feedback control.

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.
