Abstract
An apparatus for controlling a motor of a vehicle includes: a current controller generating a voltage instruction for driving the motor; a signal generator generating a magnetic pole discrimination reference signal that is combined with the voltage instruction; an inverter driving the motor on the basis of a corrected voltage instruction obtained by comparing the voltage instruction and the magnetic pole discrimination reference signal; and a processor including a control logic for deriving a response component to the magnetic pole discrimination reference signal from a driving current transferred to the motor from the inverter, and for determining a polarity of the rotor of the motor on the basis of the response component.
