IN-VEHICLE TEMPERATURE ESTIMATION DEVICE

原文（中国語）

An in-vehicle temperature estimation device is applied to an in-vehicle heated object heated by current flow. The in-vehicle temperature estimation device includes a power detection unit for detecting the supplied power supplied to the heated object, an arithmetic unit that performs a computation to estimate the temperature of a first location in the heated object, and a temperature determination unit that determines the temperature of the external air outside the heated object. The arithmetic unit performs a computation to estimate the temperature at the first location based on the supplied power detected by the power detection unit and the temperature of the external air determined by the temperature determination unit.
