Sensor fault-tolerance control technology plays a significant role in maintaining the reliability of a Steering-By-Wire system. Based on the multi-dimension Gauss Hidden Markov Model (HMM) algorithm, this paper presents a steering wheel angle sensor fault-tolerance control strategy in the Steering-By-Wire system using hardware redundancy technique. The impact of this strategy is examined through HIL (Hardware-in-Loop) experiments and test results demonstrate that the strategy proposed and employed here can effectively improve the performance of a Steering-By-Wire vehicle in terms of increasing its reliability and strengthening its security against sensor failures.
