The invention discloses a steer-by-wire redundancy control method and system and a vehicle, and relates to the field of automobile steering. The method comprises the following steps: determining a target ratio of a steering side wheel speed to a non-steering side wheel speed according to a steering angle of a steering wheel, and correspondingly adjusting at least one steering side and/or non-steering side wheel speed according to the target ratio. When the steer-by-wire system has a fault that steering cannot be controlled, the steering function of the automobile can be achieved on the basis of not depending on steering components of the steer-by-wire system, meanwhile, compared with a redundancy technology depending on hardware backup in the prior art, the size and mass of the automobile cannot be increased basically, and the cost is reduced. And the use cost is reduced while the steering function of the vehicle is ensured.

    本发明公开了一种线控转向冗余控制方法、系统及车辆,涉及汽车转向领域。该方法的步骤包括:根据方向盘转向角度确定转向侧轮速和非转向侧轮速的目标比值,根据目标比值对应调节至少1个转向侧和/或非转向侧轮速。本发明在线控转向系统出现无法控制转向的故障时,能够在“不依赖”线控转向系统的转向部件的基础上,实现汽车的转向功能,与此同时,与现有技术中依靠硬件备份的冗余技术相比,本发明基本不会增加车辆的体积和质量,在保证车辆具备转向功能的同时,降低了使用成本。
