The present invention relates to a method for controlling ramp departure of an electrically driven vehicle, which comprises the steps of: (a) determining whether a range of a transmission is D-stage; (b) determining whether a brake pedal is in a released state; (c) determining whether the rotation direction of a driving motor of the vehicle is reverse rotation; and (d) performing feedback control for setting the speed of the driving motor to 0 by applying a torque to the driving motor when the steps (a), (b) and (c) are simultaneously satisfied. An object of the present invention is to provide the method and system for controlling the ramp departure of the electrically driven vehicle which allows the vehicle to proceed on a ramp without being pushed back even when starting again.
