Abstract: A hybrid powertrain has an engine, a starter motor, and a gear train that connects the starter motor with the engine, and a motor/generator. A belt drive train connects the motor/generator with the engine. The powertrain has a first energy storage device with a first operating range of voltage and a second energy storage device with a second operating range of voltage at least partially in common with the first operating range of voltage. A controller places a switching device in an on-state so that the first energy storage device is connected with the second energy storage device or in an off-state in which the first energy storage device is disconnected from the second energy storage device. The controller causes the switching device to be in the off-state and the starter motor and the motor/generator to be powered with energy from the first energy storage device to restart the engine.

Abstract: A method for operating a vehicle including an internal combustion engine and a torque machine rotatably coupled to an input member of a transmission includes operating the vehicle in a coasting mode in response to a driver-requested axle torque and commanding engine operation in an unfueled state. A controller is employed to operate the torque machine to spin the input member to control the engine during a transition across a predetermined engine speed.
