Abstract (en)

[origin: WO2011093771A1] The present invention comprises a method and a system for estimation of a deviation for at least one model variable of a catalyst model, which estimation is based on the catalyst model and on at least one measured sensor signal from at least one sensor which is so situated that it comes into contact with exhaust gases downstream from a catalyst. According to the present invention, an actual signal is compared with an estimated signal, such that said actual signal depends on said measured sensor signal and that said estimated signal depends on at least one estimation function and represents the catalyst model's match with said actual signal, said catalyst model being spatially resolved. This comparison is thereafter used to determine at least one deviation parameter for the respective one or more estimation functions, such that each of these at least one deviation parameters describes a relation between a value for a model variable of a catalyst model and a corresponding actual value.
