Abstract (en)

[origin: DE102005047350A1] Method involves determination of an actual variable (LI) based on a lambda value, which is compared to a set point variable (LS). A corrective value (KN), for a control variable (A), is determined based on the comparison and the corrective value is stored. An error is identified when the corrective value changes abruptly. An independent claim is also included for the device for controlling an internal combustion engine.
