Zusammenfassung:	Methods and systems for a differential assembly are provided herein. In one example, a method is provided that includes operating a clutch motor coupled to a differential locking clutch to place the differential locking clutch in a locked configuration. The method further includes, after the differential locking clutch is placed in the locked configuration, reducing electric power delivered to the clutch motor at a first rate and increasing the electric power delivered to the clutch motor when it is determined that clutch disengagement is occurring based on outputs from a motor position sensor or outputs from shaft speed sensors coupled to a pair of shafts coupled to the differential locking clutch.
