Abstract
A locking differential can include first and second locking dogs and an actuator system. The first dog can include a set of first teeth fixed to a side gear of the differential. The second dog can be axially movable between first and second positions and can include an annular body coupled to a differential case for common rotation and a set of second teeth. In the first position, the first and second teeth can be disengaged. In the second position, the first and second teeth can be engaged, inhibiting relative rotation between the side gear and the differential case. At least one sensor can detect the angular position and angular velocity of the second teeth relative to the first teeth. An actuator can move the second dog from the first position to the second position based on the detected relative angular positions and velocities of the first and second teeth.
