Claim 8:
9. A method of adaptive in-drive updating for a vehicle travelling on a route divided into a number of segments, the vehicle having a controller with a processor and tangible, non-transitory memory, the method comprising:
obtaining a pre-drive energy consumption prediction for the segments in the route, via an energy consumption predictor;
executing an in-drive updating module, via the controller, at a timepoint during the route at which a completed portion of the route has been traversed and a remaining portion remains untraversed;
obtaining an actual energy consumption for the segments in the completed portion of the route;
obtaining at least one modification factor based in part on a damping coefficient, a respective weighting factor for the segments, a sum of the actual energy consumption and the pre-drive energy consumption prediction for the segments in the completed portion of the route, via the controller, the respective weighting factor being between zero and one, inclusive; and
adjusting the pre-drive energy consumption prediction for the segments in the remaining portion of the route based on the at least one modification factor, including multiplying the at least one modification factor by the pre-drive energy consumption prediction for the segments in the remaining portion;
applying the at least one modification factor (Mi) at an ith segment at a beginning of the remaining portion such that, Mi

  ,, where d is the damping coefficient, w_j is the respective weighting factor, a_j is the actual energy consumption in one of the segments of the completed portion and p_j is the pre-drive energy consumption prediction in one of the segments of the completed portion; and
controlling operation of the vehicle on the remaining portion of the route based on the adjusted pre-drive energy consumption prediction for the segments in the remaining portion of the route.
