Abstract
A system for determining a relative position of a secondary gear includes a gear assembly including a phonic wheel fixed to a primary gear and a secondary gear rotatably engaged to the first gear, a sensor configured to output a signal upon detecting a tooth of the phonic wheel, and a digital logic circuit configured to detect a revolution of the phonic wheel, to generate a primary gear tooth pulse at intervals corresponding to intervals of teeth of the primary gear based on the detected revolution of the phonic wheel, and to generate a secondary gear revolution signal at an interval corresponding to a revolution of the secondary gear based on the primary gear tooth pulse.
