The embodiment of the invention provides a steer-by-wire redundancy control method and system and a vehicle. The method comprises the following steps: determining first working state information and fault diagnosis information of a first management and control system currently executing a steer-by-wire task; receiving second working state information of a second management and control system; and determining a steering working mode based on a matching result of the first working state information, the second working state information and the fault diagnosis information. And performing working mode matching according to the first working state information, the second working state information and the fault diagnosis information to obtain a steering working mode. The steering-by-wire system can be comprehensively monitored, the fault type can be timely and accurately judged, the steering working mode and the corresponding power assisting capacity value are adjusted, and therefore it is ensured that the steering-by-wire system works stably.
本申请实施例提供线控转向冗余控制方法、系统、车辆。该方法包括:确定当前执行线控转向任务的第一管控系统的第一工作状态信息和故障诊断信息;接收第二管控系统的第二工作状态信息;基于所述第一工作状态信息、所述第二工作状态信息和所述故障诊断信息的匹配结果,确定转向工作模式。根据第一工作状态信息、第二工作状态信息和故障诊断信息进行工作模式匹配,得到转向工作模式。能够实现对线控转向系统全面监控,及时、准确的判断故障类型并对转向工作模式以及对应的助力能力值进行调整,从而确保线控转向系统稳定工作。
