Abstract

A method (600) for exiting a sailing mode of a vehicle (100) is described. The vehicle (100) comprises a clutch unit (103) which is disengaged in order to decouple a driving shaft (102) of the vehicle (100) from a driven shaft (105) of the vehicle (100), when the vehicle (100) is operated in the sailing mode. The method (600) comprises predicting (601) that a trigger for an exit of the sailing mode will occur, and initiating (602) the preparation of the clutch unit (103) for engagement, subject to predicting that a trigger for the exit of the sailing mode will occur. Furthermore, the method (600) comprises detecting (603) a trigger for the exit of the sailing mode, and adapting (604) a shaft speed (230) of the driving shaft (102), subject to detecting a trigger for the exit of the sailing mode. In addition, the method (600) comprises engaging (605) the clutch unit (103), subject to preparing the clutch unit (103) for engagement and subject to adapting the shaft speed (130), in order to exit the sailing mode.
