1. A method for predicting energy consumption of a vehicle using a statistical model, said method comprising:
- obtaining a plurality of input vectors for said vehicle at defined time intervals at a plurality of points in time, wherein each input vector is associated with each point in time of said plurality of points in time;
capturing an energy level associated with each input vector of said plurality of input vectors at each point in time for said vehicle, wherein said energy level corresponds to at least one of a stored battery power and a stored fuel level of said vehicle;
predicting a change in said energy level using a processor and said statistical model, wherein (i) the change in said energy level comprises a function of corresponding input vectors and an associated weight vector, (ii) said weight vector is derived using said plurality of input vectors and associated energy levels at each point in time of said plurality of points in time, and represents an overall effect of each said input vector on energy consumption of said vehicle, and (iii) said change in said energy level is predicted through a regression analysis of said energy level associated with each said input vector; and
providing results corresponding to the predicted change in said energy level to an audio-video output unit of said vehicle.

Abstract
A method and system includes predicting energy consumption of a vehicle using a statistical model. The method includes obtaining a plurality of input vectors for plurality of points in time, wherein each input vector includes a plurality of variables with a weight vector. Thereafter, the energy level for each input vector is captured for each point in time. Subsequent to capturing the energy level, the method includes predicting a change in energy level of the vehicle using the statistical model.
