    Abstract: Various systems and methods are provided for controlling a wastegate in the presence of a degraded wastegate valve sensor. In one example, responsive to feedback from a wastegate valve sensor being unavailable, a wastegate valve is moved to an at least partially open position in part via exhaust pressures responsive to a desired boost being within a first range. Responsive to feedback from the wastegate valve sensor being unavailable, the wastegate valve is moved toward a fully closed position at a rate responsive to boost pressure dynamics responsive to the desired boost being within a second, different range.

    Abstract: A control device used for an internal combustion engine and capable of determining an actuator operation amount is provided. The control device includes a computation element that uses engine status amounts to compute the actuator operation amount. The computation element uses a model that includes a plurality of submodels arranged in a hierarchical sequence. The computation element computes the actuator operation amount by using a parameter calculated by the lowest level submodel and changes the number of higher-level submodels to be used in combination with the lowest level submodel in accordance with the operation status of the internal combustion engine.

    Abstract: Methods and systems for real-time engine control optimization are provided. A value of an engine performance variable is determined, a value of a first operating condition and a value of a second operating condition of a vehicle engine are detected, and initial values for a first engine control parameter and a second engine control parameter are determined based on the detected first operating condition and the detected second operating condition. The initial values for the first engine control parameter and the second engine control parameter are adjusted based on the determined value of the engine performance variable to cause the engine performance variable to approach a target engine performance variable. In order to cause the engine performance variable to approach the target engine performance variable, adjusting the initial value for the first engine control parameter necessitates a corresponding adjustment of the initial value for the second engine control parameter.

    Abstract: Methods and systems for optimizing a performance of a vehicle engine are provided. The method includes determining an initial value for a first engine control parameter based on one or more detected operating conditions of the vehicle engine, determining a value of an engine performance variable, and artificially perturbing the determined value of the engine performance variable. The initial value for the first engine control parameter is then adjusted based on the perturbed engine performance variable causing the engine performance variable to approach a target engine performance variable. Operation of the vehicle engine is controlled based on the adjusted initial value for the first engine control parameter. These acts are repeated until the engine performance variable approaches the target engine performance variable.
