Abstract
A method calculates a rotational speed of a node of a linkage in a transmission allows the continued operation of the transmission even when rotational speeds are difficult to sense due to the lack of rotational speed. The method begins by sensing rotational speed at each node to define a sensed rotational speed for each node. The sensed rotational speed at each node is compared to a threshold rotational speed. The sensed rotational speed continues to be used if an absolute value of the sensed rotational speed of the node is greater than the threshold rotational speed. A calculated rotational speed is calculated when the sensed rotational speed is less than the threshold rotational speed. The sensed rotational speed value is replaced with the calculated rotational speed for the node when the sensed rotational speed is less than the threshold rotational speed.
