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 (γ) 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 (γ). 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 (γ) a warming-up temperature (α) higher than a feedback control temperature (A or B) which is set during feedback control.
