Abstract
A clutch assembly and method for controlling torque distribution of the clutch assembly based on the movement of an actuator. The clutch assembly includes a selectable clutch having a first position and a second position, an actuator, and a controller. The controller monitors current feedback from the actuator and detects motion of the actuator based on current feedback.
Claims7
A method for controlling torque transfer in a clutch assembly comprising:
- providing a selectable coupling having a first, torque transmitting position and a second, non-torque transmitting position;
- providing an actuator, the actuator acting on the selectable coupling to move the selectable coupling between the first, torque transmitting position and the second non-torque transmitting position;
- supplying voltage to the actuator;
- detecting a back electromotive force in the actuator;
- determining motion of the actuator based on the detection of a back electromotive force;
- and
- moving the selectable coupling based on the motion of the actuator.
4 more elements
A torque transmission assembly comprising:
- an actuator, the actuator includes a stator with a coil and a translator with a magnet;
- a back electromotive force detection unit generating a signal based on movement of the translator relative to the stator;
- and
- a coupling member transferring torque from a drive member to a driven member based on the signal from the back electromotive force detection unit.
