1. A system for adaptive in-drive updating for a vehicle travelling on a route, the system comprising:
a controller adapted to obtain a pre-drive energy consumption prediction for the route via an energy consumption predictor, the controller having a processor and tangible, non-transitory memory;
an in-drive updating module selectively executable by 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, the route being divided into a number of segments, execution of the in-drive updating module causing the controller to:
obtain an actual energy consumption for the segments in the completed portion of the route;
obtain 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 in the segments, and the sum of the pre-drive energy consumption prediction for the segments in the completed portion of the route, the respective weighting factor being between zero and one, inclusive; and
adjust 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;
wherein the at least one modification factor (Mi) is applied at an ith segment at a beginning of the remaining portion and obtained as:

OG Complex Work Unit Math
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
wherein operation of the vehicle on the remaining portion of the route is modified based on the adjusted pre-drive energy consumption prediction for the segments in the remaining portion of the route.
