Abstract: Systems and methods for operating a hybrid vehicle are presented. In one example, an integrated starter/generator (ISG) provides torque to restart an engine after the engine has been shut down and before engine speed is zero. An opening of a throttle is delayed to reduce driveline torque disturbances during engine restarting.

Abstract: 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.
