ABSTRACT:
This invention provides an electrically-powered steering apparatus capable of assisting a steering torque appropriately using a resolver. A reference signal is applied to a resolver arithmetic processing I/F circuit34and a resolver arithmetic processing I/F circuit36through a reference signal input means38and a microcomputer30obtains a differential in amplification factor from outputs of the resolver arithmetic processing I/F circuit34and the resolver arithmetic processing I/F circuit36when the reference signal is supplied. A correction value for computing a position from the outputs of the resolver arithmetic processing I/F circuit34and the resolver arithmetic processing I/F circuit36is computed from the obtained differential.
