Abstract:
A coolant circuit of an engine cooling apparatus includes a first passage where coolant flows through a radiator and a second passage where coolant flows without passing through the radiator. A coolant control valve controls a first passage flow rate Frad and a second passage flow rate Fsec. An outlet coolant temperature sensor detects an outlet coolant temperature Tout, which is a coolant temperature before a branching point of the first passage and the second passage. An inlet coolant temperature sensor detects an inlet coolant temperature Tin, which is a coolant temperature after a merging point of the first passage and the second passage. A coolant temperature estimator calculates a radiator coolant temperature Trad, which is a coolant temperature at a coolant exit of the radiator, when the first passage flow rate Frad is greater than or equal to a specified flow rate using equation (1). Trad = Tin - ( Tout - Tin ) × Fsec Frad ( 1 )

Claim (Index 4):
The engine cooling apparatus according to  claim 1 , further comprising a controller that controls actuation of the coolant control valve,\n wherein when increasing the flow rate of the coolant flowing through the first passage, the controller sets an actuation speed of the coolant control valve to be lower when the radiator coolant temperature Trad estimated by the coolant temperature estimator is low than when the radiator coolant temperature Trad is high.
