Abstract
A torque transfer device () for a motor vehicle includes a clutch () for transferring torque between first and second shafts (). An electromagnetic actuator () includes an axially moveable armature () for applying an application force to the clutch (). An actuator control system includes a position sensor () operable to output a signal indicative of a position of the armature (). The control system determines a target torque to be transferred by the clutch () and a target armature position based on a previously determined clutch torque vs. armature position relationship. The control system varies an electrical input to the electromagnetic actuator () to perform closed loop control of the armature position.
