Abstract
A system and method for controlling a torque transfer clutch of a vehicle. A first data source indicates if the clutch is in AWD or 4×4 mode. An integrator system monitors energy transferred across the clutch. A temperature data source measures or calculates the clutch temperature. In a first case, the integrator accumulates data of the energy across the clutch during a monitoring period that is compared to a maximum accumulated energy value and initiates a powertrain torque dependent transfer point learn routine. In a second case, the controller responds to energy accumulator cycle data in a single monitoring cycle that is compared to a maximum cycle data value. In a third case, the controller responds to clutch temperature data and compares the temperature data to a maximum temperature value. The second and third cases initiate a non-powertrain torque dependent transfer point learn routine.
