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.

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; andan interface configured to display a deceleration feedback indicator indicative of the long-term deceleration score. 2. The control system of claim 1, wherein the interface includes a deceleration feedback gauge for displaying the deceleration feedback indicator, and wherein the interface is configured to adjust the deceleration feedback indicator within the deceleration feedback gauge based on the long-term deceleration score. 3. The control system of claim 2, wherein the interface is further configured to adjust a color of at least a portion of the deceleration feedback gauge based on the instantaneous deceleration score. 4. The control system of claim 2, wherein the interface is further configured to adjust a color of at least a portion of the deceleration feedback gauge based on the long-term deceleration score. 5. The control system of claim 1, wherein the input is further indicative of a braking percentage. 6. The control system of claim 5, wherein the controller is further configured to calculate the instantaneous deceleration score based upon the vehicle deceleration, the powertrain output power and the braking percentage. 7. The control system of claim 6, wherein the controller is further configured to normalize one or more of the vehicle deceleration, the powertrain output power and the braking percentage based upon vehicle speed prior to calculating the instantaneous deceleration score. 8. The control system of claim 6, wherein the controller is further configured to calculate an adapted deceleration value prior to calculating the instantaneous deceleration score, the adapted deceleration value being based on the vehicle deceleration and the long-term deceleration score. 9. The control system of claim 8, wherein the adapted deceleration value is calculated by multiplying a normalized deceleration value by the long-term deceleration score. 10. The control system of claim 8, wherein the instantaneous deceleration score is calculated using a fuzzy logic algorithm. 11. The control system of claim 1, wherein the forgetting factor is based on whether the previous long-term deceleration score is less than the instantaneous deceleration score. 12. A method comprising: receiving input indicative at least of vehicle deceleration and powertrain output power;calculating an instantaneous deceleration score based upon the input;calculating 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; anddisplaying a deceleration feedback gauge having a deceleration feedback indicator indicative of the long-term deceleration score. 13. The method of claim 12, wherein the input is further indicative of a braking percentage. 14. The method of claim 13, further comprising: normalizing one or more of the vehicle deceleration, the powertrain output power and the braking percentage based upon vehicle speed prior to calculating the instantaneous deceleration score. 15. The method of claim 13, further comprising: calculating an adapted deceleration value prior to calculating the instantaneous deceleration score, the adapted deceleration value being based on the vehicle deceleration and the long-term deceleration score. 16. The method of claim 13, further comprising: adjusting a color of at least a portion of the deceleration feedback gauge based on the instantaneous deceleration score. 17. The method of claim 12, further comprising: adjusting a color of at least a portion of the deceleration feedback gauge based on the long-term deceleration score. 18. A display control system comprising: a controller configured to receive input indicative of an adapted vehicle deceleration value, powertrain output power and braking percentage, calculate an instantaneous deceleration score based on the input, and provide a deceleration feedback signal corresponding to a long-term deceleration score based upon the instantaneous deceleration score; anda display in communication with the controller and including a deceleration feedback gauge configured to display a deceleration feedback indicator indicative of the long-term deceleration score;wherein the adapted vehicle deceleration value is based on current vehicle deceleration and a previous long-term deceleration score. 19. The display system of claim 18, wherein the display is further configured to adjust a color of at least a portion of the deceleration feedback gauge based on the long-term deceleration score. 20. The display system of claim 18, wherein the display is further configured to adjust a color of at least a portion of the deceleration feedback gauge based on the instantaneous deceleration score.
