1. A method for estimating energy consumption of a vehicle, the method comprising:
receiving, from a remotely located computing device, standardized energy consumption data corresponding to at least one other vehicle, the standardized energy consumption data corresponding to energy consumption of the at least one other vehicle as a function of speed;
generating a scaling factor by comparing the energy consumption data corresponding to the energy consumption of the vehicle as a function of speed with the standardized energy consumption data;
scaling the standardized energy consumption data;
generating a profile of energy consumption efficiency of the vehicle based on the scaled standardized energy consumption data, a parabolic approximation of the energy consumption efficiency, and homologation data corresponding to a plurality of vehicles, wherein generating the profile of the energy consumption efficiency of the vehicle includes: identifying, with the energy consumption of the vehicle, a saturation point of energy conservation, the saturation point corresponding to a speed above threshold wherein energy efficiency diverges from the parabolic approximation; and identifying at least one or more varying grades along at least one segment of a route and modifying the profile of the energy consumption efficiency by a coefficient of the at least one other vehicle;
generating a signal to selectively adjust at least one of a speed of the vehicle, and a torque demand of the vehicle based on the profile of energy consumption efficiency of the vehicle; and
generating a correction factor comprising a zero offset value wherein generating the parabolic approximation includes using the correction factor to relocate a zero velocity point on a corresponding parabolic line.
