Abstract:
The invention relates to switching between 2WD and 4WD of a vehicle. It is suggested to increase output power of an engine (106) when changing to 4WD. An AWD coupling (120) is opened, if not already open. To provide 4WD, a PTU clutch (108) is engaged once engine power has increased. The other couplers are sequentially engaged.
