A method for controlling creep torque of a motor driven vehicle is provided. The method comprises: a downhill gradient calculation step of calculating a downhill gradient of a driving road; a time constant calculation step of calculating a filter time constant using the downhill gradient, the prepared basic creep torque, the set speed, and a compensation coefficient of basic creep torque corresponding to the set speed; and a variable control step of assigning the calculated time constant to a filter, inputting the basic creep torque to the filter, and controlling a motor by using a torque value outputted from the filter as requirement torque.
