Regenerative braking feedback display and method

摘要

Driver braking performance feedback may be conveyed to a vehicle operator as a braking efficiency score using a vehicle display system. The display system may include a vehicle display for displaying a braking efficiency indicator or gauge corresponding to the braking efficiency score. The braking efficiency score may be based on a comparison of the total regenerative braking energy recaptured during at least one braking event to a either a maximum amount of braking energy that may be recaptured during the at least one braking event or an actual total braking energy expended during the at least one braking event. The braking efficiency score may be displayed upon the completion of a braking event or upon a completion of a trip including a plurality of braking events. The display may also convey a distance corresponding to a portion of a trip distance achieved through regenerative braking.

主权项

1. A display system comprising:
a vehicle display including a trip braking efficiency indicator associated with a trip braking efficiency value; and a controller in communication with the vehicle display and configured to:
determine an amount of regenerative braking energy captured during a vehicle trip; andoutput the trip braking efficiency value as a percentage of the amount of regenerative braking energy captured and a total recapturable braking energy value associated with the vehicle trip.
