1. A physical amount estimating apparatus comprising:

  • 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.
