Zusammenfassung: | A priming system and method includes an actuator effecting engagement of a frictional element to couple input and output elements to transfer a torque. A control system initiates actuation of the frictional element through the actuator when a speed of the frictional element is below a priming threshold speed. The frictional element is primed to prepare the frictional element to transfer the torque from the input element to the output element, without delivering the torque to the output element. The frictional element in held in the primed state when the speed is below the priming threshold speed. The actuator completes actuation of the frictional element when the speed reaches the shift point, engaging the frictional element to deliver the torque to the output element. |
