An electrified vehicle having an electric machine coupled to a traction battery to selectively propel the vehicle and associated method for the electrified vehicle include receiving trip data from an external server, the trip data including a plurality of road segments of a selected route from a starting location to a destination, each road segment having an associated energy consumption and distance, calculating a distance-to-empty (DTE) based on a remaining trip distance to the destination, available energy of the traction battery, an estimated traction battery energy required for the remaining trip distance, and an overall vehicle efficiency, the estimated traction battery energy being based on a combination of the received segment energy consumption and distance of each remaining segment in the trip, and communicating the DTE to a display within the electrified vehicle to reduce fluctuations in displayed DTE during travel along routes with nonlinear energy consumption (changing energy efficiency).

Electrified vehicle control with dynamic segment-based distance-to-empty (DTE)

Systems and methods are disclosed for providing predictive distance-to-empty (DTE) assessments for vehicles that can include electric, gas, or hybrid vehicles. An example method includes determining a plurality of learned parameters of vehicle operation of a vehicle based on a plurality of energy consumption parameters of the vehicle; determining a plurality of predictive parameters of vehicle operation of the vehicle selected from any combination of weather data or navigation data, the navigation data being determined relative to a planned route and applying a DTE function for the energy source, the DTE function utilizing the plurality of learned parameters of vehicle operation, and the plurality of predictive parameters of vehicle operation of the vehicle, based on a current capacity of the energy source to determine a DTE for the vehicle.
