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.
