The invention provides a network redundancy method and device of a steer-by-wire system and a storage medium. The method comprises the steps that two hand feeling control units are used for independently controlling hand feeling force, and steering wheel turning angle information is obtained; steering wheel turning angle information is transmitted to a steering control unit through a private bus, an internal bus and/or a public bus; according to the steering wheel angle information, steering force used for driving wheels to steer is output through a steering control unit. According to the network redundancy method and device for the steer-by-wire system and the storage medium, the hand feeling control units are used for independently controlling the hand feeling force, network routing and signal redundancy are achieved through the multiple buses between the control units, and the robustness and safety of the steer-by-wire system are improved.

    本申请提供一种线控转向系统的网络冗余方法、装置及存储介质。该方法包括:通过两个手感控制单元分别独立进行手感力控制,获得方向盘转角信息;通过私有总线、内部总线和/或公有总线传输方向盘转角信息至转向控制单元;根据方向盘转角信息,通过转向控制单元输出用于驱动车轮转向的转向力。本申请提供的线控转向系统的网络冗余方法、装置及存储介质,使用多个手感控制单元单独进行手感力控制,并通过控制单元之间的多种总线实现网络路由和信号冗余,提升了线控转向系统的健壮性和安全性。
