METHODS AND SYSTEMS FOR HYBRID DRIVELINE CONTROL

摘要

Systems and methods for operating and hybrid driveline are presented. In one example, driver demand torque may be supplied to vehicle wheels via a hydraulic torque path and a friction torque path. Torque is distributed between the friction torque path and the hydraulic torque path in a way that ensures that driver demand torque is met and the friction torque path transfers torque up to its capacity.

1. A method for operating a driveline, comprising:
operating an electric machine in a torque control mode in response to a torque converter clutch torque capacity available at a transmission line pressure being greater than a driver demand torque; and operating the electric machine in a speed control mode in response to the torque converter clutch torque capacity available at the transmission line pressure being less than the driver demand torque.
