    Abstract: A method to compute, store, and inject adaptive valve timing corrections in a camless valvetrain architecture where a measurable (based on the resolution of the measuring methodology) error exists between the requested and delivered valve timing. This method is based on a measurement of the delivered valve timing, such as from a direct position sensor, (hall effect, LVDT, optical, etc.) or inferred position sensing based on valve actuator current (electronic actuation) or pressure (hydraulic actuation) feedback. This measured delivered valve timing information is used to compute offsets which, when applied to the desired timing, provide more accurate correlation between the delivered timing and the desired timing.

    Abstract: A method for controlling engine torque during disruption of a primary communication link between an engine control unit and a valve control unit in an engine is provided. The method includes determining disruption of the primary communication link between the engine control unit and the valve control unit, operating a preset valve timing schedule upon determination of disruption of the communication link between the engine control unit and the valve control unit; and sending a status message from the valve control unit to the engine control unit regarding the operational status of the valve control unit.
