Abstract
A method and apparatus for the load-dependent control of a turbocharger which is arranged in an internal combustion engine, a turbocharger includes an adjustable turbine guide apparatus which is adapted to be moved by way of an adjusting drive in the direction closing position or in the direction opening position. In order to be able to keep the response time of the turbocharger minimal during positive load changes with an optimum fuel consumption, the turbine guide apparatus is initially guided along a first predetermined characteristic curve in the direction closing position and subsequently in dependence on the charging pressure increase conditioned on the load increase according to a second predetermined characteristic curve again in the opening direction.
