The invention discloses a steer-by-wire fault tolerance device and a control method thereof. The steer-by-wire fault tolerance device comprises a steering control mechanism, a steering execution mechanism and a steering control module. The device can interrupt power transmission at the power output end of a motor through two stages of planetary gear speed reducing mechanisms; and the steer-by-wiremode can be controlled to be converted into the electric power-assisted steering mode through an electromagnetic locking device, the steering capacity can be kept under the worst condition of an automobile, and the portability during steering is improved on the premise that the driving safety of the automobile is guaranteed.

    本发明一种线控转向容错装置及其控制方法,包括转向操纵机构、转向执行机构及转向控制模块,该装置在电机动力输出端通过两级行星齿轮减速机构可以实现中断动力的传递,并且通过电磁锁止装置可以控制由线控转向模式转变为电动助力式转向模式,可以实现在汽车最坏情况下保持转向能力,且在保证汽车行驶安全性的前提下,提升转向时的轻便性。
