Abstract
A method of controlling creep torque in a motor driven vehicle is disclosed herein. In this method, a downhill gradient of a road is calculated. A filter time constant is calculated using the downhill gradient, a predetermined basic creep torque, a set speed and a compensation coefficient of the predetermined basic creep torque corresponding to the set speed. At a variable control step, the calculated filter time constant is applied to a filter, the predetermined basic creep torque is input to the filter, and a motor is controlled based on a torque value output from the filter as a request torque.
