The present invention relates to a device for controlling the creep driving of an electric vehicle and a method thereof. The present invention provides the device for controlling the creep driving of an electric vehicle and the method thereof. The present invention is applied to an electric vehicle adopting a one-foot drive mode to provide creep driving and whether or not to provide creep driving is determined actively based on the velocity of the vehicle to be able to provide the efficiency of driving to a driver and improve fuel efficiency. For the purpose, the device for controlling the creep driving of an electric vehicle, which is applied to the electric vehicle adopting a one-foot drive mode, according to the present invention comprises: a storage part for storing a reference torque map for the creep driving, which has coast regenerative torque corresponding the velocity of a vehicle recorded therein, and a reference torque map for stop; a sensor for detecting whether or not a driver takes a foot off an accelerator pedal; a vehicle velocity detecting part for detecting the velocity of the vehicle; and a control part for selecting any one from the reference torque map for creep driving and the reference torque map for stop, which are stored in the storage part, based on the velocity of the vehicle detected by the vehicle velocity detecting part according to detection signals from the sensor.

    본 발명은 전기 자동차의 크립주행 제어 장치 및 그 방법에 관한 것으로, 'One-Foot Drive' 모드가 적용된 전기 자동차에 적용되어 크립주행을 제공하되, 차속을 기반으로 크립주행 제공 여부를 능동적으로 판단함으로써, 운전자에게 운전 편의성을 제공할 수 있는 것은 물론 연비를 향상시킬 수 있는 전기 자동차의 크립주행 제어 장치 및 그 방법을 제공하고자 한다. 이를 위하여, 본 발명은 'One-Foot Drive' 모드가 적용된 전기 자동차의 크립주행 제어 장치에 있어서, 차속에 상응하는 코스트 리젠 토크가 기록된 크립주행용 기준 토크 맵과 정차용 기준 토크 맵을 저장하는 저장부; 운전자가 엑셀 페달에서 발을 떼는지를 감지하는 센서; 차속을 감지하는 차속 감지부; 및 상기 센서로부터의 감지신호에 따라 상기 차속 감지부에 의해 감지된 차속에 기초하여 상기 저장부에 저장되어 있는 크립주행용 기준 토크 맵과 정차용 기준 토크 맵 중 어느 하나를 선택하는 제어부를 포함한다.
