A motor control method includes acquiring at least one measured torque angle and two estimated torque angles, obtaining all combinations of two torque angles that are combinable with respect to a set of the at least one measured torque angle and the two estimated torque angles and performing an arithmetic operation to determine an error for each combination, selecting a control mode of the motor from control modes including a sensor mode, a sensorless mode, and a shutdown mode, the selecting being performed by referring to a table representing a relationship between the control modes and reference patterns relating to the calculated error group, and controlling the motor in accordance with the selected control mode.
