1. A system comprising:
- a controller configured to receive input indicative of vehicle deceleration and powertrain output power, calculate an instantaneous deceleration score based upon the input, and output a long-term deceleration score based upon the instantaneous deceleration score, a previous long-term deceleration score, and a forgetting factor for weighting the instantaneous deceleration score and the previous long-term deceleration score; and
an interface configured to display a deceleration feedback indicator indicative of the long-term deceleration 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 braking deceleration behavior, and providing short-term and/or long-term feedback to the driver relating to the driver'"'"'s braking deceleration behavior. The braking deceleration behavior feedback can be used to coach future braking deceleration 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 braking deceleration behavior feedback can be adapted to a driver based upon how responsive the driver is to the feedback.
