A controller (71) is used to switch the power system (1), in which the aftertreatment system is used, from a first operation mode into a second operation mode to regenerate the particulate filter (54). The transition from the first to the second operation mode is made in response to a change in load on the engine (10) and a threshold amount of time greater than zero has passed after the change in load on the engine (10).",
