Abstract
The disclosed embodiments relate to a method and to a device for controlling an internal combustion engine supercharged by an exhaust-gas turbocharger. The method includes: determining the time duration required for a specific internal combustion engine in operation, at a current operating point and with a predefined combination of settings of switching actuators, to perform an increase of the charge pressure from a current charge pressure to a target charge pressure associated with a target operating point; comparing the determined time duration with a multiplicity of stored time durations, which are each assigned to a predefined different combination of the settings of the switching actuators; and controlling the internal combustion engine with that combination of the settings of the switching actuators which permits the quickest increase of the charge pressure to the target charge pressure.
