1. A system comprising:
- a controller configured to receive input indicative of vehicle acceleration, accelerator pedal position change and powertrain output power, calculate an instantaneous acceleration score based upon the input, and output a long-term acceleration score based upon the instantaneous acceleration score, a previous long-term acceleration score, and a forgetting factor weighting the instantaneous and long-term deceleration scores; and
an interface configured to display an acceleration feedback indicator indicative of the long-term acceleration score.

Abstract
One or more embodiments of the present application may provide a system and method for monitoring driver inputs and vehicle parameters, assessing a driver'"'"'s acceleration behavior, and providing short-term and/or long-term feedback to the driver relating to the driver'"'"'s acceleration behavior. The acceleration behavior feedback can be used to coach future driving acceleration behavior that may translate into better long-term driving habits, which in turn may lead to improvements in fuel economy or vehicle range. Moreover, the acceleration behavior feedback can be adapted to a driver based upon how responsive the driver is to the feedback.
