Abstract: A shift device includes: a shift switching member including valley portions corresponding to shift positions; a motor including a rotor and a stator and configured to drive the shift switching member; a first drive system including a first control unit configured to control a voltage for driving the motor; a second drive system provided separately from the first drive system and including a second control unit configured to control a voltage for driving the motor; and a positioning member configured to establish the shift positions in a state in which the positioning member is fitted into any one of the valley portions of the shift switching member. The shift device acquires the shift positions when the motor is driven by the voltage output from one of the first and second drive systems to move the positioning member such that the positioning member continuously passes through the valley portions.

Abstract: A shift device includes: a shift switching member including a plurality of valley portions corresponding to shift positions; a motor that includes a rotor and a stator and that is configured to drive the shift switching member; and a positioning member configured to establish the shift positions in a state in which the positioning member is fitted into any one of the plurality of valley portions of the shift switching member. The shift device is configured to learn the shift positions based on a change amount of a load torque applied to the motor while the positioning member is moved to continuously pass through the plurality of valley portions.
