Abstract
A system for controlling a clutch is provided with: an action member rotatable about an 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.
