The embodiment of the invention discloses a steer-by-wire system, a control method and a storage medium. The steer-by-wire system comprises a road feel simulation device, a steering execution device and a steer-by-wire control device, wherein the road feel simulation device comprises a first torque angle sensor, a road feel motor and a road feel motor controller, the first torque angle sensor outputs two paths of steering wheel angle signals to the steer-by-wire control device according to the rotation of the steering wheel, the road sensing motor controller determines one path of steering wheel angle signal according to a rotor position signal of the road sensing motor and sends a steering wheel angle signal to the steer-by-wire control device. The system is advantaged in that the steer-by-wire control device can receive three paths of steering wheel angle signals, redundancy of the steering wheel angle signals is achieved, and when one path of steering wheel angle signal breaks down,front wheel steering control can still be conducted according to the other two paths of steering wheel angle signals.

    本发明实施例公开了一种线控转向系统、控制方法和存储介质。该线控转向系统包括路感模拟装置、转向执行装置和线控转向控制装置,路感模拟装置包括第一扭矩转角传感器、路感电机和路感电机控制器。第一扭矩转角传感器根据方向盘的转动输出两路方向盘转角信号给线控转向控制装置以及路感电机控制器根据路感电机的转子位置信号确定一路方向盘转角信号也发送给线控转向控制装置,使得线控转向控制装置可以接收三路方向盘转角信号,实现了方向盘转角信号的冗余,当其中一路方向盘转角信号出现故障时,仍可以根据另外两路方向盘转角信号进行前轮转向控制。
