A vehicle includes an engine, an electric machine, a torque converter and a controller. The torque converter includes an impeller and receives power from the engine and electric machine. The controller, in response to an absence of driver demanded torque and a difference between desired and estimated impeller speeds, adjusts a torque of the electric machine based on a difference between an estimated engine torque and a desired impeller torque in order to drive the impeller toward the desired impeller speed.
