Abstract

See full text

A method for sensor diagnostics in a seat suspension system includes: generating, by a rotational position sensor, based on a rotational position of an output shaft coupled to a suspension mechanism to move a vehicle seat relative to a vehicle body, an output signal including a sine output and a cosine output; determining, based on the sine output and the cosine output, a diagnostic indicator value; and determining, based on the diagnostic indicator value, an accuracy of the output signal to represent the rotational position of the output shaft. A second method determines accuracy of an output signal to represent a rotational position of the output shaft in a seat suspension system using the output signal and a motor position signal representing a rotational position of a motor shaft coupled to the output shaft such that rotation of the motor shaft causes rotation of the output shaft.
