A system, computer readable storage device and method for controlling torque in a hybrid electric vehicle. The method comprises determining a state of charge of an energy storage device, obtaining a reference state of charge, obtaining an error from a difference between the determined state of charge and the reference state of charge; and apportioning torque between a motor and an engine based upon the error. The motor is electrically coupled to the energy storage device and powered by the energy storage device. A state of charge (SOC) correction factor is determined based upon the error. The SOC correction factor is used to adjust a torque ratio of motor to engine torque that is determined for a given torque command.
