Abstract
A sensor failure detection device includes a storage, a predictor, a calculator and a detector. The storage stores temperature information of individual sensors. The temperature information includes measured values of temperatures. The measured values of temperatures are measured by a plurality of sensors. The predictor predicts a temperature distribution by performing a thermal fluid simulation, on the basis of the temperature information received from a remaining sensor. The remaining sensor is a sensor of the plurality of sensors other than the test target sensor. The calculator calculates a difference value between a temperature at a position of the test target sensor in the temperature distribution and a temperature measured by the test target sensor. The detector detects that the difference value is higher than a predetermined value.
