    摘要: In a method for monitoring an exhaust gas limiting value of an internal combustion engine using an engine controller, the engine controller has at least one exhaust gas sensor, and an error signal is output when the exhaust gas limiting value is exceeded. If the emissions predicted for the present driving state are ascertained with the aid of an engine model and compared to the signal of the exhaust gas sensor or a comparison value for the emission derived therefrom, the prescribed driving cycle may be taken into account when certifying a limiting value monitoring system and a defective system may be reliably recognized in practical operation even in atypical driving states without resulting in erroneous triggering of error signals.

    摘要: The invention relates to a system for controlling an internal combustion engine (100), in particular a self-igniting internal combustion engine. A signal (U) for triggering a performance-determining final controlling element (105) is stored in a characteristics map (110) for each of a corresponding fuel quantity (QK) to be injected into the engine. The signal values stored in the characteristics map (110) are then corrected in dependence upon a predetermined relationship of a signal corresponding to the value for the fuel quantity (QK) to be injected and a signal corresponding to the value for the actually injected fuel quantity (QKI).

    摘要: In the method for monitoring the sensor device (1), which supplies an analog output signal over a bidirectional output line (3) to an analysis unit (2) for evaluation, a predetermined test signal is applied to a sensor output in a monitoring phase, which is received in the analysis unit (2) and evaluated. In order to initiate the monitoring phase at any arbitrary time without the need of an additional connecting line between the sensor device and the analysis unit, a trigger signal of a predetermined trigger level is transmitted by the analysis unit (2) to the sensor device (1) over the output line (3) and is detected in the sensor device, which generates the predetermined test signal and transmits it to the analysis unit (2) over the bidirectional connecting line (3). A sensor device and connected analysis unit designed to perform this method are also described.
