The invention discloses a redundant electric steering system and an operation method thereof. The redundant electric steering system comprises a steering wheel, the steering wheel is connected with a steering column, the steering column is connected with an intermediate shaft, the intermediate shaft is connected with a steering tie rod, the steering column is provided with a C-EPS system, and the intermediate shaft is provided with a DP-EPS system. The C-EPS system comprises a first ECU, a first TAS sensor, a first motor and a first motor position sensor. The DP-EPS system comprises a second EAU, a second TAS sensor, a second motor and a second motor position sensor; the first ECU and the second ECU are connected with the public CAN and receive ignition signals at the same time. The first ECU and the second ECU are connected through a private CAN. The method has a good redundancy mechanism, various failure conditions can be well handled, and the safety of automobile steering is improved.

    本发明公开了一种冗余式电动转向系统及其运行方法,包括转向盘,转向盘连接有转向管柱,转向管柱连接有中间轴,中间轴连接有转向横拉杆,所述转向管柱上设有C‑EPS系统,所述中间轴上设有DP‑EPS系统;所述C‑EPS系统包括第一ECU、第一TAS传感器、第一电机和第一电机位置传感器;所述DP‑EPS系统包括第二EAU、第二TAS传感器、第二电机和第二电机位置传感器;所述第一ECU和第二ECU分别与公共CAN相连,并同时接收点火信号;所述第一ECU和第二ECU之间还经过私有CAN相连。本发明具有良好的冗余机制,能够较好的应对各种失效情况,提高了汽车转向的安全性。
