Abstract:
1. A resolver signal processing method for resolver signal for obtaining information about a rotation inputted to an end of a torsion bar whose other end is fixed, by computation based on a resolver signal outputted from plural resolvers attached to both ends of the torsion bar, said resolver signal processing method comprising: a first step for obtaining a first data value within a predetermined range of data values relating to rotations inputted to said plural resolvers based on a data value relating to said rotation obtained from a known rotation input serving as a reference set as a first reference value; a second step for obtaining a second data value out of the predetermined range of said inputted data values relating to the rotations based on a second reference value set to a different value from said first reference; and a third step for obtaining information about a rotation inputted to an end of the torsion bar whose other end is fixed using said first data value and said second data value.
