Abstract

A method for operating a powertrain system of a vehicle includes determining an initial creep torque command in an operator-selected direction of travel, adjusting the initial creep torque command responsive to an operator braking request and responsive to a change in direction of vehicle speed relative to the operator-selected direction of travel, and operating the hybrid powertrain to generate axle torque in response to the adjusted creep torque command.
