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 fuel control system for an internal combustion engine includes a first module that determines a corrected injected fuel mass based on an engine temperature and a measured burned fuel mass and a second module that determines a raw injected fuel mass based on the corrected injected fuel mass and the engine temperature. A third module regulates fueling to a cylinder of the engine based on the raw injected fuel mass.

Abstract: A fuel control system for regulating fuel to cylinders of an internal combustion engine during an engine start and crank-to-run transition includes a first module that determines a plurality of step-ahead cylinder air masses (GPOs) for a cylinder based on a plurality of GPO prediction models. A second module regulates fueling to a cylinder of the engine based on the plurality of step-ahead GPOs until a combustion event of the cylinder.
