Fault detection of suspension height sensors within a semi-active vehicle suspension

A control system for a suspension system of a vehicle, the control system comprising:

• a set of suspension height sensors operably coupled to a set of wheels of the vehicle for measuring current suspension height data;
• a vehicle speed sensor operably coupled to the vehicle for measuring vehicle speed data;
• and
• a controller operably coupled the set of suspension height sensors and the vehicle speed sensor,
• wherein the set of suspension height sensors comprises multiple instances of an individual suspension height sensor operably coupled to corresponding ones of the set of wheels,
• wherein the controller is configured to:
• receive the current suspension height data and the vehicle speed data;
• determine whether the vehicle is in a steady-state condition based on the vehicle speed data;
• responsive to the vehicle being determined to be in the steady-state condition, perform a comparison of the current suspension height data to a variable range, a fixed range, and a fixed threshold of suspension height data;
• and
• determine an operation state of the individual suspension height sensor based on the comparison.
