Abstract
A steering angle sensing system includes at least one steering angle sensing device for outputting an analog signal representative of a steering angle position of a steering wheel. A first processor is operably coupled to the at least one steering angle sensing device and is disposed proximate the at least one steering angle sensing device. The first processor receives the analog signals output by the at least one steering angle sensing device, computes a steering angle value based upon the analog signals, and outputs a pulse width modulated signal representative of the computed steering angle value. A second processor is disposed non-proximate the at least one steering angle sensing device and is operably coupled to the first processor to thereby receive the pulse width modulated signal representative of the computed steering angle value.
