Abstract
A method for controlling a hybrid electric vehicle powertrain includes operating an engine driveably connected to first vehicle wheels, providing an electric motor driveably connected to second vehicle wheels, shifting a gear selector between a forward drive position and a reverse drive position, reducing vehicle speed to or lower than a reference speed, and using a transmission located between the engine and the first wheels and the electric motor to produce reverse or forward drive corresponding to the position to which the gear selector is shifted.
