摘要： A system and method for managing a powertrain in a vehicle determines a number of vehicle conditions, and compares them to predetermined conditions to determine whether a secondary axle of the vehicle should be automatically connected to or disconnected from the powertrain. In general, if the speed of the vehicle is above some predetermined speed threshold, the secondary axle is disengaged to increase fuel economy. Conversely, if the speed of the vehicle is below some predetermined threshold, the secondary axle is typically engaged to help maximize the capture of regenerative braking energy during a braking event. Additional vehicle conditions may be examined, and exceptions to the general rule utilized, to further enhance the control strategy.

摘要： 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.
