Method for operating an internal combustion engine, computer program product, computer program and control and / or regulating device for an internal combustion engine

摘要

Method for operating an internal combustion engine (1), in which a sensor (5) for detecting and / or an actuator (10) for setting an operating variable of the internal combustion engine (1) is monitored for the presence of a malfunction, wherein the monitoring in a first operating point the internal combustion engine (1) with a lower load and at a second operating point of the internal combustion engine (1) is carried out at a higher load, characterized in that for a single monitoring operation, the two operating points are set alternately and at least one of the two operating points, wherein the sensor (5) measured and / or set by the actuator (10) operating variable is compared with a predetermined value for the respective operating point and the sensor (5) and / or the actuator (10) for correcting the difference between the measured or set operating variable and the predetermined value is adapted, in which case, in in which one of the two operating points a temporal change of the adaptation value falls short of a predetermined value, the adaptation process terminated at this operating point at least temporarily, switched to the other of the two operating points and the adaptation process for this other of the two operating points is performed or resumed.
