Arc position encoder with an extended angular position sensing range

A method of sensing an angular position of a rotating object over a 360-degree angular position range using an arc position encoder comprising a 180-degree angular position sensing range, the method comprising:

• receiving one or more polarity transition signals from one or more polarity transition sensors disposed on one or more of a first end and a second end of a base of the arc position encoder, the one or more polarity transition signals indicating a transition of one of a first magnetic pole and a second magnetic pole of a magnetic target coupled to the rotating object so as to rotate about an axis of rotation located in a center of a circle defined by the base, wherein the first and second magnetic poles are disposed on opposite ends of the magnetic target so as to generate a uniform magnetic field, into the 180-degree angular position sensing range of the arc position encoder, and another one of the first and second magnetic poles out of the 180-degree angular position sensing range;
• receiving one or more proximity signals from one or more magnetic field sensors disposed within the base between the first and second ends, the one or more proximity signals indicating relative proximity of the one of the first and second magnetic poles within the 180-degree angular position sensing range of the arc position encoder to each of the one or more magnetic field sensors;
• and
• determining the angular position of the rotating object within the 360-degree angular position range based at least in part on the one or more polarity transition signals and the one or more proximity signals.
