The invention discloses an automobile drive-by-wire mechanical dual-mode free steering system and an automobile, and relates to the technical field of automobile design and manufacturing, the automobile drive-by-wire mechanical dual-mode free steering system comprises a steering wheel assembly, a steering shaft assembly and a steering pull rod assembly which are sequentially connected, a shell is arranged at the bottom end of the steering wheel assembly, and a dual-mode converter is arranged in the shell; the dual-mode converter comprises a sleeve, a spline, an elastic piece, an elastic clamping piece and a position sensor, and a clamping sliding groove matched with the elastic clamping piece is formed in the inner wall of the shell. According to the dual-mode converter, the meshing state and the non-meshing state of the key groove and the spline are reflected through the relative position information of the elastic clamping piece and the clamping sliding groove, the relative position information of the elastic clamping piece and the clamping sliding groove is transmitted to the controller through the position sensor, and then the controller controls failure and effectiveness of the steering mode. The steering-by-wire mode and the mechanical steering mode of the automobile can be stably and flexibly switched only by simply lifting and pressing the steering wheel assembly, operation is convenient, and the structure is simple.

    本发明公开一种汽车线控机械双模自由转向系统及汽车,涉及汽车设计和制造技术领域,包括依次连接的方向盘组件、转向轴组件和转向拉杆组件,方向盘组件底端设置有外壳,外壳内设置有双模转换器,双模转换器包括套筒、花键、弹性件、弹性卡接件和位置传感器,外壳的内壁上设置有与弹性卡接件适配的卡接滑槽。本发明的双模转换器利用弹性卡接件与卡接滑槽的相对位置信息反应键槽与花键的啮合和非啮合状态,通过位置传感器将弹性卡接件与卡接滑槽的相对位置信息传输给控制器,再通过控制器控制线控转向模式的失效与生效,仅需进行简单的上抬、下压方向盘组件的动作,即可平稳实现汽车线控转向模式和机械转向模式的灵活切换,操作方便,结构简单。
