Zusammenfassung:	A method for having a vehicle follow a desired curvature path is provided. The vehicle has at least one differential with a differential lock connected to at least one driven wheel axle of the vehicle. The method includes providing information regarding state of the differential lock, the state being either that the differential lock is activated or unlocked, and when the differential lock is activated, calculating a yaw moment of the vehicle caused by the differential lock; and compensating for a deviation from the desired curvature path caused by the yaw moment such that a resulting steering angle is equal to or less than a maximum allowed steering angle of the vehicle. The compensation is a feed forward compensation.
