<P>PROBLEM TO BE SOLVED: To provide an abnormality determination method for determining abnormalities of temperature sensors at an early stage. <P>SOLUTION: An abnormality determination method for determining abnormalities of a plurality of temperature sensors which are provided at respective temperature detection targets and detect temperature for each temperature detection target comprises: a temperature data acquisition step (S1, S7, and S13) for acquiring temperature data detected by each of the respective temperature sensors; a temperature order calculation step (S3, S9, and S15) for calculating the order of the temperature data of the respective temperature sensors; and an abnormality determination step (S4, S10, and S16) for determining whether or not there are any abnormalities in the temperature sensors, by comparing the temperature order of the temperature data calculated in the temperature order calculation step and the temperature order set in advance based on temperatures expected to be detected by the respective temperature sensors. <P>COPYRIGHT: (C)2012,JPO&INPIT |
