주행로의 내리막기울기를 산출하는 내리막기울기산출단계; 내리막기울기, 미리 마련된 기본크립토크, 설정속도, 설정속도에 대응되는 기본크립토크의 보상계수를 이용하여 필터 시정수를 산출하는 시정수산출단계; 및 산출된 시정수를 필터에 대입하고, 기본크립토크를 필터에 입력하며, 필터로부터 출력된 토크값을 요구토크로 하여 모터를 제어하는 가변제어단계;를 포함하는 모터주행차량의 크립토크 제어방법이 소개된다.
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.
