1. A method for controlling an internal combustion engine, comprising:
determining, based on performance characteristics, a first quantity characterizing an actual injected fuel amount and a second quantity characterizing a desired fuel amount to be injected;
comparing the first quantity to the second quantity; and
defining, based on a result of the comparison, a first correction value for correcting a fuel amount and a second correction value for correcting an air amount, wherein the first correction value is limited to a selected maximum value.
