Patent ID: 10876468

Abstract:
A method for controlling a turbocharging system with a turbocharging stage for an internal combustion engine, wherein the turbocharging stage comprises a compressor and a turbine and the turbine is adjustable via a VTG control. The method includes: acquiring an operating state target variable; adjusting a maximum VTG control criterion to implement the torque increase by increasing a boost pressure, wherein adjusting the maximum VTG control criterion includes: determining a target boost pressure; determining a VTG target position as a function of the target boost pressure; determining an actual exhaust back pressure; determining a maximum exhaust back pressure; determining the VTG control criterion taking into account the difference between the actual exhaust back pressure and the maximum exhaust back pressure. The VTG control criterion limits the VTG target position such that an accelerated adaptation of an actual boost pressure to the target boost pressure) takes place.
