METHOD FOR LEARNING AT LEAST ONE PUMP FEATURE OF PUMP OF FEED MODULE OF SCR CATALYST SYSTEM

The present invention relates to a method (100) for learning at least one pump feature of a pump (32) for a feed module (32) of an SCR-catalyst system (10), including the following steps: (110) obtaining a to-be-learned reference value (nPmpRef) of at least one pump feature (p, T, q), wherein the reference value (nPmpRef) is saved in a reference matrix; and (120) obtaining a to-be-learned deviation value (DeltanPmp), wherein the deviation value is the deviation between the at least one pump feature and the reference value (nPmpRef), and the to-be-learned deviation value is saved in a deviationmatrix. 本发明涉及一种用于学习SCR-催化器系统（10）的输送模块（32）的泵（32）的至少一个泵特征的方法（100），具有以下步骤：获取（110）所述至少一个泵特征（p、T、q）的、待学习的参考值（nPmpRef），其中，所述参考值（nPmpRef）存储在参考矩阵中；以及获取（120）待学习的偏差值（△nPmp），所述偏差值是所述至少一个泵特征与所述参考值（nPmpRef）的偏差，并且，将所述待学习的偏差值存储在偏差矩阵中。
