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 3):
The engine cooling apparatus according to  claim 2 , wherein the time constant is set based on a speed of a vehicle, in which the engine is installed, to be a smaller value when the speed is high than when the speed is low.
