Abstract
According to one or more embodiments a steer by wire steering system includes a handwheel actuator that provides a commanded position for a rack of a vehicle. The steer by wire steering system further includes a roadwheel actuator that moves the rack to a rack position based on the commanded position from the handwheel actuator. The steer by wire steering system further includes a diagnostic apparatus to compute a reference position based on the commanded position, and to compute a reference tracking error based on a difference between the reference position and the rack position. The diagnostic apparatus further determines a fault condition with the steer by wire system using the reference tracking error.
