The method also includes determining, for the selected route, a route energy consumption profile and calculating an estimated remaining charge for the vehicle battery at an end of the selected route based on the state of charge of the vehicle battery and the route energy consumption profile. The method also includes, in response to a determination that the estimated remaining charge is less than a lower limit of the vehicle battery charge range, determining a target vehicle speed profile based on the at least one route characteristic, the vehicle energy consumption profile, and the state of charge of the vehicle battery. ## Claims ### Claim 1 A method for estimating a remaining range of a vehicle battery charge, the method comprising: determining, for a selected route, a route energy consumption profile based on at least one route characteristic of a portion of the selected route and a vehicle energy consumption profile;
