The invention discloses a double-source double-winding motor steer-by-wire system and a fault-tolerant control method thereof. The double-source double-winding motor steer-by-wire system comprises a steering wheel, a steering column assembly, a road sensing assembly, a double-winding motor steering execution device, a power source fault-tolerant device, a main controller and an electromagnetic clutch; the double-source double-winding motor steer-by-wire system has dual hardware redundancy functions of a motor winding and a power supply, and when one winding breaks down, the other winding can complete the steering action under the drive of a power supply; when one power supply fails, the other power supply drives the winding to complete the steering action; when both the winding and the power supply fail, the steering action can still be completed through mechanical steering; and the vehicle is prevented from completely losing the steering capability due to power supply or winding faults, and the vehicle steering safety is enhanced.

    本发明公开了一种双源双绕组电机线控转向系统及其容错控制方法,系统包括:方向盘,转向管柱总成、路感总成、双绕组电机转向执行装置、电源容错装置、主控制器及电磁离合器;本发明具备电机绕组、电源双重硬件冗余功能,单个绕组出现故障,可以由另一个绕组在电源驱动下完成转向动作;单个电源出现故障,可以由另一个电源驱动绕组完成转向动作;当绕组和电源均出现故障,仍可通过机械转向完成转向动作;避免电源或绕组故障导致车辆完全丧失转向能力,增强了车辆转向安全性。
