Summary: | A method of controlling motor torque for learning a resolver offset of an electric vehicle includes steps of: determining whether a condition for offset learning mounted to a main drive motor and to an auxiliary drive motor is satisfied; controlling an output torque of a learning drive motor, which includes a resolver to perform the offset learning among the main drive motor and the auxiliary drive motor to a zero torque, when the condition for performing the offset learning is satisfied; increasing an output torque of a non-learning drive motor, which includes a resolver not performing the offset learning among the main drive motor and the auxiliary drive motor by a torque reduction amount, when the learning drive motor outputs zero torque; and performing the offset learning of the resolver mounted to the learning drive motor. |
