Abstract
A vehicle includes an engine, and a transmission including a torque converter having an impeller. The vehicle further includes an electric machine configured to provide drive torque to the impeller. The impeller is selectively coupled to the engine via a clutch. At least one vehicle controller is configured to, in response to the engine being OFF, the transmission being in DRIVE, a vehicle speed being zero and a brake pedal being released beyond a threshold position, command the electric machine to provide a torque to the impeller. The torque is a predetermined feedforward torque adjusted by a feedback torque that is based on a difference between measured and calculated speeds. The speeds may be the speeds of the electric machine.
