1. A vehicle comprising:

  • a set of drive wheels;

    an energy source configured to store available energy;

    a torque-generating device powered by the energy source and configured to generate an input torque;

    a transmission configured to receive the input torque and deliver an output torque to one or more of the drive wheels to thereby propel the vehicle; and

    a controller that is configured, as the vehicle travels along a predetermined travel route, to;

    predict, via a first logic block of the controller, an energy consumption of the available energy using onboard data and offboard data, the first logic block predicting the energy consumption including calculating a summation of a propulsion system energy consumption and an auxiliary device energy consumption for the travel route based on the onboard and offboard data;

    calculate, via a second logic block of the controller, a correction factor using real-time vehicle data, including actual vehicle speed data and actual auxiliary device load data, and driver technique data, including data indicative of a demonstrated driving behavior of an operator of the vehicle;

    determine a corrected energy consumption as a function of the predicted energy consumption and the correction factor using an error correction loop between the second logic block and the first logic block; and

    execute a control action with respect to the vehicle using the corrected energy consumption, the control action including changing a logic state of the vehicle.
