Abstract

A method for limiting an air charge of an internal combustion engine. A maximum permissible pre-controlled charge and an exhaust-gas temperature-dependent delta charge are determined by means of a PI controller. A total permissible charge is determined on the basis of the maximum permissible pre-controlled charge and the exhaust-gas temperature-dependent delta-charge, and the air charge of the internal combustion engine is limited by the total permissible charge.
