Provided is a motor control apparatus that can easily distinguish between a current sensor error and a rotation-angle sensor error, without making the current sensor a duplex system. An MGECU (140) estimates the W-phase current on the basis of a V-phase current detected by a current sensor (125), and estimates the V-phase current on the basis of a detected W-phase current. An actual torque of MG2 is estimated on the basis of the detected V-phase current and the estimated W-phase current, and the actual torque of MG2 is also estimated on the basis of the detected W-phase current and the estimated V-phase current. Then, an evaluation is made whether an error is a current sensor (125) error or a resolver (124) error, on the basis of the differences between the torque command value for MG2 and both the estimated actual torque.
