Abstract

A method for controlling an internal combustion engine in which in each case the lambda value is ascertained by evaluating a measuring signal of a lambda probe. In this context, two combustion periods of the internal combustion engine are compared to each other. In the two combustion periods, in a single cylinder the lambda value is induced once in the direction of a lambda increase and once in the direction of a lambda decrease.
