Abstract
A vehicle includes an engine and a traction motor. A clutch is configured to selectively mechanically couple the engine to the traction motor. A controller or controllers are provided that are configured to command a change in magnitude of an electric current supplied to the electric machine. The command is made in response to initiation of the clutch engaging the traction motor to the engine. The change in magnitude of the electric current ensures the speed of the traction motor remains generally constant during clutch engagement while a speed of the engine is less than that of the traction motor.
