Abstract
In one example, a method for controlling powertrain operation in a vehicle is provided, the powertrain having an engine and an automatic transmission, the engine having at least an electrically actuated cylinder valve. The method includes changing gears from a first discreet gear ratio to a second discreet gear ratio of the transmission; and increasing engine torque during a torque phase of said gear change by changing operation of the electrically actuated cylinder valve, and decreasing engine torque during an inertia phase of said gear change.
