Abstract
A physical amount estimating apparatus including first outputting means for outputting a first physical amount that does not include a hysteresis characteristic, second outputting means for outputting a second physical amount that has a predetermined physical relationship to the first physical amount and includes a hysteresis characteristic, hysteresis removing means for calculating a corrected value with the hysteresis characteristic removed therefrom based on the second physical amount, and estimating means for estimating a third physical amount based on a physical relationship between the first physical amount and the corrected value.
