Abstract: <P>PROBLEM TO BE SOLVED: To establish an estimation technique with higher estimation accuracy based on probability theory.  <P>SOLUTION: A drift estimation calculator 4 for estimating a proper drift amount is provided for each of a plurality of sensors 2. The drift estimation calculator 4 calculates a statistic output distribution based on an output distribution of each of the plurality of sensors 2, calculates a statistic drift amount distribution as a distribution of a drift amount of the sensors 2, presumes a first probability density function based on the statistic output distribution, presumes a second probability density function based on the statistic drift amount distribution, and estimates a proper drift amount for each sensor based on the first probability density function and the second probability density function by following the probability theory (Bayes' theorem). From the hypothesis of calculating a probability density function based on the statistic output distribution and a statistic drift amount distribution, the known probability theory can be used for estimating a drift of a sensor, the drift can be highly accurately estimated by the established probability theory, and judgment of whether a correction or exchange of the sensor is necessary can be made rationally.  <P>COPYRIGHT: (C)2003,JPO
