Method for teaching at least one pump feature of a pump of a delivery module of an SCR catalyst system

摘要

The invention relates to a method (100) for teaching at least one pump feature of a pump (32) of a delivery module (32) of an SCR catalyst system (10), comprising the steps of: determining (110) reference values to be taught (nPmpRef) of the at least one pump feature ( p, T, q), wherein the reference values (nPmpRef) are stored in a reference matrix; and determining (120) deviation values to be learned (ΔnPmp) which are deviations of the at least one pump feature from the reference values (nPmpRef) and which are stored in a deviation matrix.
