FLUID TEMPERATURE ESTIMATING DEVICE - MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHA

Title:

FLUID TEMPERATURE ESTIMATING DEVICE

Document Type and Number:

Japanese Patent JP3575350

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: 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.
SOLUTION: 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.
