An exhaust temperature measurement device (30) is provided with a first exhaust temperature output unit (31), a second exhaust temperature output unit (32), an over-correction determination unit (33a), and a measured-value output unit (33b). The first exhaust temperature output unit outputs an uncorrected value corresponding to the output of a temperature sensor. The second exhaust temperature output unit outputs a corrected value on the basis of a response-delay model. The over-correction determination unit determines whether the corrected value has been over-corrected, on the basis of the uncorrected value and the corrected value. The measured-value output unit outputs the corrected value as the measured value if the over-correction determination unit does not determine an over-correction, and outputs a value which differs from the corrected value as the measured value if the over-correction determination unit determines that an over-correction has occurred. As a result, it is possible to minimize, as much as possible, a reduction in the accuracy of the measured value caused by over-correction. |
