Abstract
Method (200) for determining and / or adjusting an actual quantity of recirculated exhaust gases (122) that is recirculated from an outlet (132) of an internal combustion engine (103) to an inlet (131) of the internal combustion engine (103); wherein the method (200) comprises, - Determining (201) a first point in time at which the internal combustion engine (103) is in overrun mode; - Acquisition (202) of sensor data relating to the chemical composition of exhaust gases (122) at the outlet (132) of the internal combustion engine (103) at the first time point; and - Determining (203) information regarding the actual quantity of recirculated exhaust gases (122) and / or adjusting (203) the actual quantity of recirculated exhaust gases (122) based on sensor data.
