A method of controlling a shiftable clutch in a drive train between a
front axle and a rear axle of a motor vehicle with a four-wheel drive is
provided. One axle is driven directly and the other axle, as a hang-on
system, is coupled by way of the clutch. In order to create a method of
controlling the shiftable clutch in a drive train between the front axle
and the rear axle, and a corresponding system with an improved
availability of the full four-wheel drive characteristic with a
corresponding protection of the driving dynamics of the overall vehicle,
the clutch is continuously acted upon by torque in an adjustable manner
by way of a pilot control measure.
