ABSTRACT:
A method for controlling a variable turbine geometry of an exhaust gas turbocharger which supercharges an internal combustion engine for driving a motor vehicle. The turbine geometry is set as a function of the operating load of the internal combustion engine between the opening position in idling and the closed position in full load operation. The turbine geometry is brought into an operating position predetermined for the prevailing load point. To improve the non-steady-state operating performance of the exhaust gas turbocharger and the internal combustion engine, in particular during long acceleration phases of the motor vehicle, the turbine geometry is guided during a switching pause for changing gear levels of the motor vehicle into a switching pause position which is independent of the operating load. In the switching pause position a reduced flow cross section of the turbine for the exhaust gas stream is set. This prevents a drop in supercharger rotation speed during the switching pause and the related delay in buildup of the torque and boost pressure of the internal combustion engine.
