  • Method and system for a variable displacement engine
    Patent number: 10221787
    Abstract: Methods and systems are provided for monitoring torque delivery in a variable displacement engine using air flow metered via a throttle body model. During conditions when air flow estimation can be inaccurate, such as at wide open throttle, an induction ratio applied to the engine is constrained to 1.0, even if the operator torque demand is low. VDE degradation is inferred based on the commanded induction ratio relative to an actual induction ratio estimated based on the torque delivery.
    Type: Grant

    Date of Patent: March 5, 2019

  • Methods and systems for providing transient torque response
    Patent number: 9175629
    Abstract: A method and system for providing a suitable engine torque response during a transient condition is presented. In one example, when a desired inlet manifold pressure is greater than a throttle inlet pressure of a first throttle, a second throttle positioned upstream from the first throttle is opened to increase the throttle inlet pressure. The method may provide an appropriate torque response while minimizing impact on fuel economy.

  • Methods and systems for torque control
    Patent number: 9174637
    Abstract: Methods and systems are provided for improving surge control. When surge conditions are approached, a reference governor reduces engine airflow at a slower rate and to a higher level than the engine airflow required to meet the reduced torque demand. The excess torque resulting from the extra airflow is offset by applying a negative torque on the driveshaft via an electric machine coupled to the engine or via alternate engine actuator adjustments.

  • PRESERVING COMBUSTION STABILITY DURING COMPRESSOR-SURGE CONDITIONS
    Publication number: 20140316675
    Abstract: A method to avoid over-dilution of an intake-air charge of an engine includes, during a first condition, applying at least some feedback control to the opening and closure of a valve that adjustably admits exhaust to the intake-air charge. During a second condition predictive of compressor surge, no feedback control is applied to the opening or the closure of the valve. Rather, feedforward control is applied to the closure of the valve so that stability in the engine is maintained even during surge conditions.

  • Methods and systems for turbocharger control
    Patent number: 8439796
    Abstract: Methods and systems are provided for controlling a vehicle engine, the engine including a turbocharger and a transmission. One example method comprises, operating the transmission at a first lower gear with a first boost level, increasing the boost from the first boost level before completing a shift from the first lower gear to a second higher gear, and after completing the shift, operating the transmission at the second higher gear with the increased boost.
