Abstract

The invention relates to a regulating method for a turbocharger (1) with a turbine (4) which has a variable turbine geometry (VTG) provided with adjustable guide blades (5), having the following method steps: a) closing the guide blades (5) of the variable turbine geometry (VTG), as a function of the present operating point of the internal combustion engine which is turbocharged by means of the turbocharged (1), to the maximum possible closing position of the guide blades (5) for said operating point, and b) regulating the charge pressure (P2) by adjusting the position of the guide blades (5) in a closed regulating loop.
