1. A method of controlling an actuator for a drivetrain disconnect assembly, comprising:
actuating a solenoid of an actuator to drive a first clutch member along an axis and relative to a second clutch member between a first position and a second position, and when the solenoid is in the second position, teeth of the first clutch member are not axially overlapped with teeth of the second clutch member;
actuating the solenoid to drive the first clutch member from the second position to a third position, and when the solenoid is in the third position the teeth of the first clutch member are partially axially overlapped with the teeth of the second clutch member; and
actuating the solenoid to drive the first clutch member from the third position to a fourth position, and when the solenoid is in the fourth position, the teeth of the first clutch member have a greater extent of axial overlap with the teeth of the second clutch member than when the solenoid is in the third position, wherein the movement of the first clutch member between the second position and the third position is at a faster rate than is the movement of the first clutch member: a) between the first position and the second position; and b) between the third position and the fourth position.
