Abstract
A method for moving a vehicle in a reverse direction is provided. The method includes: providing an internal combustion engine, a transmission, and an electric machine; adjusting a valve timing of either an intake valve or an exhaust valve during a non-firing mode of the internal combustion engine to reduce a rotational resistance; and, rotating the internal combustion in a backwards or reverse direction so that the vehicle moves in a reverse direction.
