Position detector correction method and electrically-powered steering apparatus |
摘要 |
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 circuit 34 and a resolver arithmetic processing I/F circuit 36 through a reference signal input means 38 and amicrocomputer 30 obtains a differential in amplification factor from outputs of the resolver arithmetic processing I/F circuit 34 and the resolver arithmetic processing I/F circuit 36 when the reference signal is supplied. A correction value for computing a position from the outputs of the resolver arithmetic processing I/F circuit 34 and the resolver arithmetic processing I/F circuit 36 is computed from the obtained differential. <IMAGE>
