ABSTRACT:
A method for controlling engagement and release of friction clutches in a multiple-ratio transmission for a hybrid electric vehicle powertrain uses electric motor torque to augment engine torque as a power-on downshift is commanded. Near the end of a downshift event, total powertrain torque is modulated or reduced to reduce torque disturbances.
