ABSTRACT:
A power transfer assembly for use in a four-wheel drive vehicle has a torque transfer mechanism equipped with a power-operated clutch actuator for controlling adaptive engagement of a friction clutch and a control system for controlling actuation of the clutch actuator. The control system and its method of operation are adapted to control actuation of the clutch actuator based on whether the vehicle is operating in an engine drive mode or an engine coast/braking mode.
