Title:
FLUID TEMPERATURE ESTIMATING DEVICE
Document Type and Number:
Japanese Patent JP2001091370
Kind Code:
A
Abstract:
To make estimable the actual temperature of a fluid accurately even if there is a response delay in a temperature sensor in the case of, for example, a transitional sudden change in temperature.
The temperature of a fluid of which the velocity of flow changes is detected by a temperature sensor 31, and the velocity of flow of the fluid is estimated by a flow velocity estimating means 52. A temperature correcting means 53 is constituted in such a way as to correct the output of the temperature sensor 31 according to the velocity of flow estimated by the flow velocity estimating means 52.
