Abstract

A method for controlling a creep torque of a motor-driven vehicle includes a gradient calculating step of calculating a gradient of a traveling road, and a time constant calculating step of calculating a time constant of a filter using the gradient, a preset basic creep torque, and a sliding speed limiting value. A variable controlling step substitutes the calculated time constant for the time constant of the filter, inputs the basic creep torque to the filter, and controls the motor using a torque value output from the filter as a demanded torque.
