Abstract
A method for controlling an engine restart in a hybrid electric powertrain, including the steps of stopping the engine, using an electric power source and an electro-mechanical actuator connected to the source to engage a gear and stroke to zero torque capacity a dry clutch of a dual-clutch transmission, initiating an automatic engine restart, and increasing the torque capacity of the clutch to a desired torque capacity during the engine restart.
