The invention provides a redundant steer-by-wire system, a control method and a vehicle. The system comprises a vehicle state observation unit, a first control unit, a second control unit, a first motor driving unit, a second motor driving unit, a six-phase road sensing motor and a six-phase steering motor. Wherein the vehicle state observation unit comprises a two-way torque sensor, the first control unit and the second control unit respectively receive a main voltage value and an auxiliary voltage value from the two-way torque sensor, and calculate a first target torque value and a second target torque value according to the respectively received voltage values; the two target torque values are sent to a first motor driving unit and a second motor driving unit, so that the first motor driving unit drives the six-phase road feeling motor based on at least one of the two target torque values; and the second motor driving unit drives the six-phase steering motor based on at least one of the two target torque values.

    本申请提供一种冗余线控转向系统、控制方法以及车辆,该系统包括:车辆状态观测单元、第一控制单元、第二控制单元、第一电机驱动单元、第二电机驱动单元、六相路感电机以及六相转向电机。其中,车辆状态观测单元包括双路扭矩传感器,第一控制单元和第二控制单元分别从双路扭矩传感器接收到主电压值和副电压值,根据各自接收到的电压值计算出第一目标扭矩值以及第二目标扭矩值,并将两个目标扭矩值向第一电机驱动单元和第二电机驱动单元发送,以便第一电机驱动单元基于两个目标扭矩值中的至少一个目标扭矩值驱动六相路感电机,以及第二电机驱动单元基于两个目标扭矩值中的至少一个目标扭矩值驱动六相转向电机。
