The invention discloses a redundant backup system of a steer-by-wire device, a control method of the redundant backup system, a vehicle and the steer-by-wire device, the steer-by-wire device comprises at least one CAN transceiver, a controller and at least one set of driving modules, and the system comprises a detection module used for detecting the running state of the controller; and the redundant backup controller is connected with the CAN transceiver and is used for transmitting and outputting a steering control signal to the driving module through the CAN transceiver when the running state of the controller is abnormal, so that the driving module drives the steering motor and the road sensing motor. According to the system, the steering motor and the road feeling motor can be controlled when the steer-by-wire device is abnormal, so that steering control and driving safety of the vehicle can be guaranteed, the design can be simplified, and the cost can be reduced.
本发明公开了一种线控转向装置的冗余备份系统及其控制方法和车辆,线控转向装置,线控转向装置包括:至少一个CAN收发器、控制器和至少一组驱动模块,系统包括:检测模块,检测模块用于检测控制器的运行状态;冗余备份控制器,冗余备份控制器与CAN收发器相连,用于在控制器的运行状态出现异常时,通过CAN收发器发送输出转向控制信号给驱动模块,以使驱动模块驱动转向电机和路感电机。本发明的系统可以在线控转向装置出现异常时控制转向电机和路感电机,从而能够保障车辆的转向控制以及行车安全,并且能够简化设计,降低成本。
