Abstract: A system for controlling turbocharger shaft speed for an internal combustion engine (ICE) includes sensors and actuators and control modules in communication with the sensors and actuators. The control modules store and execute control logic that generates a predicted shaft speed from turbocharger shaft speed data. A shaft speed control algorithm (SSCA) is selectively initialized. The SSCA generates lower and upper limits to turbocharger flow corrections applied via the actuators. Closed loop control outputs are applied selectively to the actuators to control a mass flow through a compressor of the turbocharger. The SSCA selectively determines the shaft speed has exceeded a threshold, and the actuators alter a pressure ratio of the ICE. The SSCA operates the turbocharger stably within predefined hardware limits at an optimum shaft speed while maintaining constant flow across a range of pressure ratios. A long-term memory learning process trims turbocharger performance.

Abstract: A computer-implemented method that, when executed by data processing hardware of a motor vehicle including a turbocharger having a turbine, causes the data processing hardware to perform operations. One operation includes receiving an accelerator pedal position input indicating that a vehicle accelerator pedal has moved to an overrun position. Another operation includes receiving one or more vehicle performance parameter inputs each corresponding to a measured vehicle performance parameter. Yet another operation includes calculating a vehicle dynamic score based on the one or more vehicle performance parameter inputs. A further operation includes determining a target boost profile based on the calculated vehicle dynamic score. Another operation includes instructing one or more outputs of the vehicle to transition to a dynamic mode to generate an increased turbine power based on the target boost profile.

Abstract: A vehicle system includes a vehicle engine, a plurality of intake and exhaust valves coupled to the vehicle engine configured to adjust performance of the vehicle engine, and a camshaft coupled to the plurality of intake and exhaust valves and configured to control timing of the intake and exhaust valves. The vehicle system also includes a camshaft phaser configured to adjust the position of an engine's camshaft. Moreover, the vehicle system includes a vehicle processor. The vehicle processor is configured to store data including vehicle data, and apply increased oil pressure to the camshaft phaser based on vehicle data such that oil pressure is increased at a predetermined vehicle data range of camshaft phaser instability to prevent future camshaft position instability.
