Abstract:
1. A method for calculating Distance to Empty (DTE) in an electric vehicle, comprising: calculating, by a controller, a learning DTE by blending an average fuel efficiency stored during a past charge cycle and an average fuel efficiency within a current single charge cycle; calculating, by the controller, a section DTE using an average fuel efficiency over a certain section within the current single charge cycle; and simultaneously displaying, by the controller, the learning DTE and the section DTE on a cluster, wherein the calculating of the learning DTE comprises: calculating a past driving average fuel efficiency (R calculating an air conditioning average energy consumption rate (R_AC) during past driving; calculating a past driving average fuel efficiency (R calculating a current driving fuel efficiency (R blending the past driving average fuel efficiency (R calculating a final learning DTE from a driving fuel efficiency (R
