    摘要: A method for improving drivability of the powertrain system having an accelerator control includes determining a first transmission input speed having an associated first power loss and operating said transmission using said first transmission input speed. An operational parameter relating to said accelerator control is determined and a second transmission input speed responsive to said operational parameter and having an associated second power loss is determined. The value of at least one of said first and second power loss is biased based on said operational parameter. The first power loss is compared to said second power loss subsequent to the biasing. A third transmission input speed is determined and the transmission is operated using the third transmission input speed.

    摘要: A method for controlling a hybrid powertrain system including an engine selectively operative in one of an all-cylinder state and a cylinder deactivation state based upon power costs includes determining engine power costs for each operating range state of the transmission, determining a system power cost, selecting a preferred cost and corresponding engine operating points, selecting a preferred operating range state, selecting the engine state, and controlling the engine based upon the selected operating range state, the selected engine state, and the engine operating points.
