摘　　要：以多维高斯隐式马尔可夫模型为基础,采用软硬件冗余技术,提出了线控转向汽车转向盘转角传感器的容错控制策略,并通过硬件在环试验进行了验证。结果表明,该策略可应用于线控转向汽车转向盘转角传感器的容错控制,有效提高其安全性和可靠性。Based on multi-dimension Gaussian hidden Markov model and by adopting hardware and software redundancy techniques,a fault-tolerance control strategy for the steering wheel angle sensor of a steer-by-wire vehicle is proposed and verified by a hardware-in-the-loop experiment. The results demonstrate that the strategy proposed can be applied to the fault-tolerance control of steering wheel angle sensor in a steer-by-wire vehicle,effectively improve the safety and reliability of the angle sensor.
