OBJECTIVE

Establish new ways of improving the fuel economy of trucks by exploiting connected vehicle technologies by relying on the optimal use of real-time information available through vehicle-to-vehicle (V2V) communication.

APPROACH

Develop technologies that use a new dynamic optimization that overcomes the difficulties in traditional methods and provides a fast, highly adaptable framework for the dynamic environment provided by ad-hoc V2V communication and the use of android devices for faster turn around times.  The technologies will be evaluated via extensive simulations on three different scales, as well as experiments with the help of Navistar to obtain verification.

OUTCOMES

We have developed the fundamental principles that allow one to optimize the fuel economy of heavy duty vehicles while taking into account grade, wind and traffic information.  We also developed a matlab code to carry out real-tim optimization.  This shall be translated to lower level codes for on-board implementation.
