Abstract
In a powertrain for a motor vehicle that includes an engine, a transmission driveably connected to the engine and wheels of the vehicle, an electric machine for transmitting power to at least some of the vehicle wheels, a method for controlling the powertrain includes operating the engine and transmission to produce a wheel torque at a desired vehicle speed with the transmission operating in a desired gear in response to a demanded wheel torque, increasing the demanded wheel torque due to the vehicle ascending a grade, determining a magnitude of wheel torque able to be produced in the desired gear, using the electric motor to provide a second wheel torque in combination with wheel torque whose magnitude is equal to or greater than the wheel torque being produced in the desired gear, and continuing to operate the transmission in the desired gear.
