Limiting regenerative torque for a hybrid electric powertrain

摘要

Regenerative torque is limited for a hybrid electric powertrain of a vehicle. A transmission controller determined torque limit is validated by a vehicle controller. The vehicle controller validates the torque limit using, individually or in combination, an actual status of a torque converter clutch, a detected status of the torque converter clutch, or a speed of the vehicle.

主权项

1. A method of controlling an electrified vehicle powertrain comprising:
limiting regenerative braking using a new torque limit based upon a current regenerative braking torque limit and a status of a torque converter clutch, wherein the clutch status is an actual condition of the clutch, the actual condition of the clutch is a slipping state and the new limit is determined as the greater of the current limit or a current regenerative braking request.
