Vehicle system and method for adapting lift pedal regeneration
First Claim
Patent Images
1. A method, comprising:
- controlling an electrified vehicle by increasing lift pedal regeneration in response to exceeding a system regeneration limit; and
commanding a torque command signal that is derived from the increased life pedal regeneration to an electric machine to decelerate the electrified vehicle at a desired deceleration rate during a subsequent lift pedal event.

15. A vehicle system, comprising:
-
an electric machine; and a control module in communication with said electric machine and configured to increase a negative torque demand commanded to said electric machine in response to exceeding a system regeneration limit during a braking event of said vehicle system, and wherein said control module is configured to decrease said negative torque demand commanded to said electric machine if said system regeneration limit is not exceeded during said braking and a driver braking behavior meets a predefined criteria. - View Dependent Claims (16, 17, 18)
