Abstract
Disclosed herein is a method of generating a fault tolerant sensor signal for a motor control system in a vehicle steering system. The method includes receiving at least three sensor signals indicative of a sensed parameter and generating a plurality of parameter pair signals responsive to the least one sensor signal of the at least three sensor signals. Additionally, the method includes selecting one parameter pair signal of the plurality of parameter pair signals and generating a measured parameter signal responsive to the selecting.
