Various embodiments of the teachings herein include methods for operating a vehicle. The methods may include: accessing a travel plan identifying an intended destination and a predicted state of the energy store including a predicted value for a parameter of the energy store upon arrival; determining an instantaneous location; determining a predicted value for the first operating parameter based on the location and the travel plan; measuring an instantaneous value for the parameter; calculating a first deviation between the predicted value and the instantaneous value; calculating an expected final value for the parameter upon reaching the intended destination based on the instantaneous value; calculating a second deviation between the predicted final value and the expected final value; indicating to an operator both of the deviations; and executing one or more changes to controls of the drive system in response to at least one of the two deviations.
