1. A system for controlling a clutch for regulating transmission of torque about an axis to a vehicle, comprising:
an action member rotatable about the axis;
a motor drivingly connected to the action member to impart a rotational motion about the axis to the action member;
a conversion mechanism drivingly connected to the action member to convert the rotational motion about the axis into an axial motion;
a clutch member constituting the clutch and drivingly connected to the conversion mechanism so as to be driven by the axial motion, the clutch member being movable axially bidirectionally from a first position where the clutch is disconnected, through a second position, to a third position where the clutch is connected; and
a controller configured to measure and compare a rotational angle of the motor with a reference value to determine at which of the first position, the second position, and the third position the clutch member is, and wherein the controller is configured to determine whether the determined position of the clutch member agrees with a requested position and, if agreement is not determined, apply to the motor a current to transit the clutch member to the requested position.
