1. A method for limiting an air charge of an internal combustion engine, the method comprising the following steps:
determining, using a PI controller, a maximum permissible pre-controlled charge and an exhaust-gas temperature-dependent delta charge;
determining a total permissible charge based on the maximum permissible pre-controlled charge and the exhaust-gas temperature-dependent delta-charge; and
limiting the air charge of the internal combustion engine by the total permissible charge.
