Abstract
A method of decreasing vibration during release of a stop gear of a vehicle can be applied to an eco-friendly vehicle for decreasing vibration generated when a driver releases a P step of a gear lever while torsion occurs in a drive shaft of the vehicle. Reaction force torque of a driving motor is controlled so as to output reaction force that has been generated in a parking sprag by a driving motor when torsion occurs in the drive shaft after entrance of the gear lever into the P step, so as to decrease vibration generated because torsion reaction force of the drive shaft vanishes at the same time.
