  • Patent number: 10619554
    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).
