1. A method for optimizing vehicle performance, the method comprising:
- identifying at least one operating scenario from a list of predetermined operating scenarios, each of which indicates one of a potential for optimizing and no potential for optimizing;
determining that there is a potential for optimizing fuel economy based on the at least one operating scenario identified;
determining, by at least one computer module, an optimized drive torque;
detecting a driver requested drive torque;
determining if the driver requested drive torque is in response to at least one driving related condition;
setting an arbitrated drive torque to the optimized drive torque when determining the driver requested drive torque is not in response to at least one driving related condition, and setting the arbitrated drive torque to the driver requested drive torque when determining the driver requested drive torque is in response to the at least one driving related condition;
monitoring a driver resistance to setting the arbitrated drive torque to the optimized drive torque; and
setting the arbitrated drive torque between the driver requested drive torque and the optimized drive torque when driver resistance is detected.

Abstract
Disclosed is an exemplary method for optimizing vehicle performance. The method includes determining an optimized drive torque for maximizing vehicle fuel economy and detecting a driver requested drive torque. A determination is made on whether the driver requested drive torque is performance related or safety related. The arbitrated drive torque is set to the optimized drive torque when it is determined that the driver requested drive torque is not performance and safety related. The arbitrated drive torque is set to the driver requested drive torque when it is determined that the driver requested drive torque is either performance or safety related.
