Providing availability of rotary position sensor information after hardware failures

A method for providing rotary position sensor information, the method comprising:

• receiving, with an electronic processor, a first set of signals from a first bridge circuit of a rotary position sensor;
• receiving, with the electronic processor, a second set of signals from a second bridge circuit of the rotary position sensor;
• in response to the receipt of the first set of signals from the first bridge circuit stopping, identifying, with the electronic processor, a fault associated with the first bridge circuit;
• receiving, with the electronic processor, a pulse signal;
• determining a pair of quadrants from based on the pulse signal;
• determining, with the electronic processor, a rotary angle based on the pulse signal and the second set of signals from the second bridge circuit by correlating the pair of quadrants to the second set of signals;
• and
• controlling a motor based on the rotary angle.

A non-transitory, computer-readable medium storing instructions that, when executed by an electronic processor, perform a set of functions, the set of functions comprising:

• receiving a first set of signals from a first bridge circuit of a rotary position sensor;
• receiving a second set of signals from a second bridge circuit of the rotary position sensor;
• in response to the receipt of the first set of signals from the first bridge circuit stopping, identifying a fault associated with the first bridge circuit;
• receiving a pulse signal;
• determining a pair of quadrants based on the pulse signal;
• determining a rotary angle based on the pulse signal and the second set of signals from the second bridge circuit by correlating the pair of quadrants to the second set of signals;
• and
• controlling a motor based on the rotary angle.
