Abstract
A gear shifter performs an abutment learning, having a reference value learner that sets a reference value of a position signal when abutting a drive object to a stopper, and reduces warpage by (i) an all phase power supply supplying to the electric current to all of the plural phase coils of the direct current motor, and (ii) by reducing an amount of the electric current supplied to the coils, and by decreasing a pressing force of the drive object pressing the drive object against the stopper. The reference value determined at a warpage diminish time enables a reduction of variation of the reference value due to an influence of the warpage, thereby setting a robust reference value to account for an environmental condition such as a temperature change, for an accurate shift operation of the gear shifter.
