Abstract
A device and a method for controlling an internal combustion engine in which, starting from the comparison between a measured and an expected value for a lambda signal, a correction value is specified for a fuel signal characterizing the fuel quantity, or an air signal characterizing the air quantity. Depending on the operating state, an output signal of a characteristics map and/or the output signal of a closed-loop control are/is used as the correction value.
