The invention provides a steering system of a steer-by-wire passenger vehicle, the vehicle and a control method of the steering system. The steering system comprises a steering wheel system, the steering wheel system comprises a steering wheel, a first steering angle sensor and a controller ECU1, and the first steering angle sensor is used for detecting a steering angle signal of the steering wheel; the backup control mechanism comprises a steering ball, a second steering angle sensor and a controller ECU2, and the second steering angle sensor is used for detecting a steering angle signal of the steering ball; the main controller ECU is connected with the steering executing mechanism, and the main controller ECU is selectively connected with at least one of the controller ECU1 and the controller ECU2; when the main controller ECU is connected with the controller ECU1, the steering wheel system controls the steering executing mechanism to conduct steering action. And when the main controller ECU is connected with the controller ECU2, the backup control mechanism controls the steering execution mechanism to perform steering action. According to the scheme, the problem that in the prior art, a steering system cannot guarantee the safety of passengers when a steering wheel system breaks down is solved.

    本发明提供了一种线控转向乘用车的转向系统、车辆、转向系统的控制方法。转向系统包括:方向盘系统,方向盘系统包括转向盘、第一转角传感器和控制器ECU1,第一转角传感器用于检测转向盘转角信号;备份操纵机构,备份操纵机构包括转向球、第二转角传感器和控制器ECU2,第二转角传感器用于检测转向球转角信号;主控制器ECU,主控制器ECU与转向执行机构连接,主控制器ECU可选择地与控制器ECU1、控制器ECU2中的至少一个连接;主控制器ECU与控制器ECU1连接时,方向盘系统控制转向执行机构进行转向动作;主控制器ECU与控制器ECU2连接时,备份操纵机构控制转向执行机构进行转向动作。本方案解决了现有技术中转向系统在转向盘系统故障时无法保障乘员安全的问题。
