    摘要： A hybrid transmission is operative to transfer power between an input member and first and second torque machines and an output member in a fixed gear operating range state. The first and second torque machines are connected to an energy storage device. A method for controlling the hybrid transmission includes determining an output torque command at the output member, determining motor torque constraints for the first and second torque machines and determining power constraints for the energy storage device, iteratively selecting candidate input torques transferable to the input member and associated output torques, determining a second torque constraint associated with the candidate input torque, determining a third torque constraint associated with the candidate input torque, and determining a preferred input torque comprising the candidate input torque that achieves the commanded output torque at the output member and satisfies the motor torque constraints for the first and second torque machines, satisfies the power constraints for the energy storage device, and satisfies the second and third torque constraints associated with the candidate input torque when operating in the fixed gear operating range state.

    摘要： A method of operating a vehicle powertrain system comprising an electric motor and transmission where the electric motor is operably and selectively coupled to the transmission and adapted to provide an output torque contribution thereto, and the electric motor has a predetermined maximum motor output torque and a predetermined minimum motor output torque which are used to determine a range of permissible control points for at least one transmission control parameter. The method includes establishing a motor torque reserve by performing at least one of decreasing the predetermined maximum motor output torque to a maximum reserved motor output torque and increasing the minimum motor output torque to a minimum reserved motor output torque, wherein the maximum reserved motor output torque and the minimum reserved motor output torque are used in place of the predetermined maximum motor output torque and the predetermined minimum motor output torque, respectively, to determine the range of permissible control points for the at least one transmission control parameter.
