Lasterfassung mit Diagnose bei einer Brennkraftmaschine

摘要

A system for the determination of loading with diagnostics for an internal combustion engine, in which the filtered main load signal and the secondary load signal, which is also filtered, are evaluated to form the load signal necessary for the regulation of an internal combustion engine is characterized by signal limitations being imposed on the main load signal in both full-load operation and part load operation or idle running, and the main load signal being monitored for plausibility with a secondary load signal in the range excluding return flow. In the event of an implausible main load signal, the load signal will only be derived from the secondary load signal. A number of correction factors are taken into consideration for plausibility checks, so that the maximum and minimum values can be modified to the prevailing conditions as is appropriate. Furthermore, the signal from the lambda probe may be used for plausibility checking.
