Abstract
A method for controlling a transmission of a powertrain system includes executing a single source shortest path search to identify a preferred shift path originating with an initial powertrain state and terminating at a target powertrain state, wherein the single source shortest path search employs transition-specific costs and situational costs to identify the preferred shift path. The preferred shift path is executed to achieve the target powertrain state.
