Abstract: In a motor vehicle driveline having an automatic transmission driveably connected to a transfer case whose output is continually connected to a first output, a clutch, selectively engaged in response to a control signal, driveably connects a second output to the first output. A digital computer continually monitors the occurrence of a change of clutch slip, input torque and a torque rate change to control the torque transmitted by the clutch to the second output. The control causes the clutch to transmit torque to the second output having a constant fraction of the input clutch torque and another portion that is proportional to the clutch slip. This result simulates the torque slip characteristics produced by transfer case having both a center differential mechanism and a viscous clutch.

Also, in a stabilized operation, operation condition may be varied so that an optimal operation condition is automatically searched.
