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.

A method of controlling vibration reduction of a vehicle is capable of efficiently reducing vibration occurring when entering a P range on a ramp. The method includes: when an input to a parking range is received, determining whether or not a predetermined condition for entering a vibration reduction control mode is satisfied; when the entering condition is satisfied, calculating a motor torque for reducing vibration due to backlash by using the driving information; controlling a driving motor so as to output the calculated motor torque; controlling the parking device such that the parking range is engaged; determining whether or not a brake is released; and if the brake is released, reducing a motor torque output by the driving motor so that vibration due to the backlash is reduced.

Disclosed are a vehicle equipped with an electric motor, which is capable of preventing damage to a mechanical axle-fixing device when a parking range is selected under a specific condition, and a parking control method therefore. The parking control method includes calculating output torque of the electric motor to stop the vehicle when a parking (P) range is selected in the situation in which a specific condition is satisfied, controlling the electric motor in response to the output torque, and activating a driving shaft fixing unit when the vehicle is stopped by the controlling.
