Fault detection and isolation using sliding mode observer for steer-by-wire

Recent advances toward Steer-by-Wire (SbW) technology have promised significant improvements in vehicle, safety, stability, dynamics and maneuverability. The conventional mechanical linkages between the steering wheel and the front wheel are removed in this system. While the complete separation of...
