The invention relates to the field of vehicle steering systems, and discloses a multi-mode steering multi-axle steering system and a control method thereof.The multi-axle steering system comprises a control assembly and multiple sets of steering assemblies, the multiple sets of steering assemblies and axles are installed in a one-to-one correspondence mode, and each set of steering assembly comprises a steering engine and a shell fixed to the corresponding axle; one end of the straight pull rod is hinged to a steering plumbing arm of the steering engine, and the other end of the straight pull rod is hinged to a lower knuckle arm of a steering knuckle on any side of the axle; two ends of the tie rod are respectively hinged to upper knuckle arms of two steering knuckles of the axle; the control assembly is connected with all the steering machines and used for receiving a steering instruction of a driver, obtaining the turning angle of each axle according to the steering instruction and controlling a steering plumbing arm of the steering machine of each axle to rotate to the corresponding target angle. The multi-shaft steering system has the effect that a steering angle sensor at the steering knuckle can be omitted, so that the production cost of the multi-shaft steering system is reduced.

    本申请涉及车辆转向系统领域,公开了一种多模式转向的多轴转向系统及其控制方法,其中多轴转向系统包括控制组件和多组转向组件,多组转向组件分别与各车桥一一对应安装,各组转向组件包括:转向机,固定于车桥的壳体;直拉杆,其一端铰接于所述转向机的转向垂臂,另一端铰接于所述车桥任意一侧转向节的下节臂;横拉杆,其两端分别铰接于所述车桥的两个转向节的上节臂;所述控制组件和各个所述转向机连接,用于接收驾驶员的转向指令并根据转向指令得到各车桥的转角,控制各车桥所述转向机的转向垂臂转动至各自对应的目标角度。具有可以取消转向节处的转角传感器,从而降低多轴转向系统的生产成本的效果。
