Regenerative braking feedback display and method
First Claim
1. A display system comprising:
- a display including a braking efficiency indicator associated with a braking efficiency score; and
a controller configured to;
determine an amount of regenerative braking energy captured during a braking request; and
output the braking efficiency score based on a comparison of the amount of regenerative braking energy captured and a total braking energy value associated with the braking request when vehicle speed drops below a threshold.

Abstract
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.
