Abstract
An actual value of a turbine flow cross section of a turbocharger of an internal combustion engine in a motor vehicle is set for a change in the load on the internal combustion engine from a larger load value to a smaller load value. The actual value setting of the smaller load value is delayed to a setpoint value that is specified for the smaller load value under stationary conditions. A device controls the progression of the method.
