1. A method for improving energy efficient operation of a vehicle, wherein a microprocessor performs the following steps:
- monitoring vehicle operating characteristics comprising analyzing vehicle load and road topology and analyzing at least one of weather conditions, traffic conditions, road conditions, tire pressure, vehicle maintenance history, and driver operating patterns;
modeling operation of said vehicle, said modeling utilizing said vehicle operating characteristics to estimate energy consumption rates of said vehicle across an allowable speed range, wherein said allowable speed range comprises a maximum allowable speed corresponding to a maximum legal speed and a minimum allowable speed some speed interval less than said maximum legal speed;
determining a potential control speed within the allowable speed range on the basis of said energy consumption rates; and
generating a control output to said vehicle comprising setting a control speed based upon the potential control speed.
