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 2):
The engine cooling apparatus according to  claim 1 , wherein when a value of the radiator coolant temperature Trad calculated immediately before the first passage flow rate Frad becomes less than the specified flow rate is an initial coolant temperature,\n based on the initial temperature and outside temperature, the coolant temperature estimator calculates the radiator coolant temperature Trad when the first passage flow rate Frad is less than the specified flow rate as a value that varies with a first-order lag element from the initial coolant temperature to the outside temperature in accordance with time elapsed from when the first passage flow rate Frad becomes less than the specified flow rate, and the coolant temperature estimator sets a time constant of the first-order lag element to a smaller value when a velocity of air current blown against the radiator is high than when the velocity is low.
