Zusammenfassung:	The present invention relates to an apparatus and a method for displaying a distance-to-empty of a vehicle. According to the present invention, the apparatus for displaying a distance-to-empty of a vehicle comprises: a mass estimation unit which estimates an increase or decrease state of the mass of a travelling vehicle; an energy efficiency calculation unit which calculates a driving energy efficiency on the basis of a past learned energy efficiency based on a mass level corresponding to an increased or decreased mass of the travelling vehicle and a current learned energy efficiency of the vehicle; a distance calculation unit which calculates a distance-to-empty of the vehicle on the basis of the calculated driving energy efficiency; and a control unit which determines whether to update the distance-to-empty displayed on a display on the basis of the mass level corresponding to the increased or decreased mass of the travelling vehicle, and on the basis of the distance-to-empty calculated by the distance calculation unit, updates displayed information of the display. 본 발명은 차량의 주행가능거리 표시 장치 및 방법에 관한 것으로서, 본 발명에 따른 차량의 주행가능거리 표시 장치는, 주행 중 차량의 질량의 증감 상태를 추정하는 질량 추정부, 상기 차량의 주행 중 증감된 질량에 대응되는 질량 레벨 기반의 과거 학습 전비 및 차량의 현재 학습 전비를 기반으로 구동 전비를 연산하는 전비 연산부, 상기 연산된 구동 전비에 기초하여 차량의 주행가능거리를 연산하는 거리 연산부, 및 상기 차량의 주행 중 증감된 질량에 대응되는 질량 레벨에 기초하여 디스플레이에 표시되는 주행가능거리의 업데이트 여부를 결정하고, 상기 거리 연산부에 의해 연산된 주행가능거리에 기초하여 디스플레이의 표시 정보를 업데이트 하는 제어부를 포함한다.
