Abstract

A power transmission system and method that includes a first shaft, a second shaft, and a planetary gear assembly between the first shaft and the second shaft. The planetary gear assembly includes at least a first gear ratio and a second gear ratio. A first coupling assembly associated with the first gear ratio and a second coupling associated with the second gear ratio. The system and method determines an input speed of the second gear ratio based on the speed of the second shaft and varies the speed of the first shaft relative to the input speed of the second gear ratio wherein the second coupling assembly operates based on the speed of the first shaft relative to the input speed of the second gear ratio.
