Method of controlling vibration reduction of vehicle

A method of controlling vibration reduction of a vehicle, the method comprising:

• determining, by a controller, whether or not an input for switching to a parking range is received;
• if the input is received, determining, by the controller, whether or not a predetermined condition for entering a vibration reduction control mode is satisfied by using driving information collected in the vehicle;
• when the predetermined condition is satisfied, calculating, by the controller, a motor torque for reducing vibration due to backlash in a parking device by using the driving information;
• controlling, by the controller, a driving motor so as to output the calculated motor torque;
• controlling, by the controller, the parking device such that the parking range is engaged;
• determining, by the controller, whether or not a brake is released;
• and
• if the brake is released, decreasing, by the controller, a motor torque output by the driving motor so that vibration due to the backlash is reduced.
