Abstract
A power transfer assembly for a motor vehicle includes a clutch protection system to prevent damage to an actively-controlled multi-plate mode clutch of the power transfer assembly. The clutch protection system includes a transfer case control module (TCCM) and an engine control module (ECM) configured to regulate the distribution of torque applied from an engine to front and rear output shafts of the power transfer assembly. The TCCM is in operable communication with the engine control module ECM, wherein TCCM is configured to detect slip in the actively-controlled multi-plate friction clutch and to communicate with the ECM to selectively reduce the output torque of the engine in response to detected slip.
