Abstract: A digital power take-off system includes an input shaft and an output shaft connected to a planetary gear. An actuator is mechanically coupled to the planetary gear to mechanically control a rotational speed of the output shaft. An output shaft sensor detects the output shaft rotational speed. Controller circuitry receives a desired output shaft rotational speed, receives the output shaft rotational speed from the output shaft sensor, and determines a difference between the rotational speeds. The controller circuitry outputs an operating parameter, based on the determined difference, to the actuator such that the actuator modifies a gear ratio of the planetary gear to maintain the desired output shaft rotational speed over a range of input shaft rotational speeds.

Abstract: A method calculates a time for which a force is to be applied to a strut to have the strut lockingly engage a notch of a notch plate. The notch plate has a plurality of notches equidistantly spaced about a surface of the notch plate at a predetermined distance from each other. The method begins by measuring a rotational speed of the notch plate. The method then identifies the predetermined distance between the notches in the notch plate. The predetermined distance is divided by the measured speed to create a positioning time. A pivot time is added to the positioning time allow the strut to travel along the notch plate and into the notch a sufficient distance to physically lock the pocket plate and the notch plate together.
