  • Publication number: 20250050783
    Abstract: An apparatus provides information on a distance to empty (DTE) of a vehicle and an information providing method is performed thereby. The apparatus includes a display device configured to display DTE information of a vehicle and a controller configured to control operation of the display device. The controller determines low fuel efficiency-related information and high fuel efficiency-related information based on a current vehicle driving condition. The controller determines a low DTE value and a high DTE value based on the low fuel efficiency-related information, the high fuel efficiency-related information, and a current available battery energy. The controller also determines a current DTE value indicating a real-time DTE and controls operation of the display device to display the low DTE value, the high DTE value, and the current DTE value.
