description A control device and a method for controlling an exhaust gas aftertreatment system comprising a diesel particulate filter is provided. The method comprises a step of, in response to a determination that a temperature of an exhaust gas entering the diesel particulate filter is equal to or below 325° C., controlling a NOx concentration of the exhaust gas entering the diesel particulate filter to be equal to or less than 600 ppm. An exhaust gas aftertreatment system as well as a vehicle comprising the control device are also described.
