摘要
A powertrain system includes an engine mechanically coupled to an electro-mechanical transmission selectively operative in one of a plurality of transmission operating range states and one of a plurality of engine states. A method for controlling the powertrain system includes determining a current transmission operating range state and engine state, determining at least one potential transmission operating range state and engine state, determining preferability factors associated with the current and potential transmission operating range state and the engine state wherein the preferability factors associated with potential transmission operating range states include transmission input speed trip preferability factors, preferentially weighting the preferability factors for the current transmission operating range state and engine state, and selectively commanding changing the present transmission operating range state and engine state based upon the preferability factors.
