Abstract (en)

The system has four units establishing four coefficients. One of the units establishes a coefficient representing the extent to which the NOx trap is full of NOx. A unit combines the coefficients and obtains a fifth and final coefficient. A comparator unit compares the fifth coefficient with a threshold so that in the event of the threshold being exceeded, a request is issued to trigger purging of the NOx trap.
