Abstract
A method of parking control for a vehicle equipped with an electric motor independent from a transmission includes calculating external force applied to wheels when predetermined conditions including shifting to a parking (P) stage are satisfied, determining whether a drive shaft fixing apparatus activated according to shifting to the P stage is combined, and controlling the electric motor such that a torque having a magnitude less than the external force is applied to the wheels in a direction opposite to the external force when the drive shaft fixing apparatus is determined to be combined.
