The invention discloses a steering method based on an articulated four-wheel-drive chassis, the articulated four-wheel-drive chassis comprises an articulated frame formed by hinging two supports, eachsupport is provided with two walking wheels driven by an independent rotary driving device, and the four walking wheels on the two supports are located in the same plane. The hinged axes of the two supports coincide with the intersection point of the two diagonal lines of an assumed rectangle, the four walking wheels on the two supports are correspondingly arranged at the four corners of the assumed rectangle respectively, and the hinged four-wheel drive chassis further comprises a steering drive assembly used for driving the two supports to rotate relatively. According to the steering method, steering is controlled by combining driving of the steering driving assembly and active adjustment of the rotating speed of each walking wheel, so that the instantaneous steering origin of the articulated frame is located on the axis of the walking wheel at the rear end, and the articulated frame has the advantages of being good in driving flexibility, simple and compact in structure, easy to manufacture, low in cost, stable and reliable in work, accurate in steering path and the like.

    本发明公开了一种基于铰接式四驱底盘的转向方法,铰接式四驱底盘包括由两个支架铰接而成的铰接式车架,每个支架上均安装有两个由独立旋转驱动装置驱动的行走车轮,两个支架上的四个行走车轮位于同一平面内,两个支架的铰接轴线与一假定矩形的两条对角线交点重合,两个支架上的四个行走车轮分别对应设于假定矩形的四个角上,铰接式四驱底盘还包括用于驱动两个支架相对转动的转向驱动组件。转向方法是结合转向驱动组件的驱动和主动调节各行走车轮的转速来控制转向,使铰接式车架的瞬时转向原点位于后端行走车轮的轴线上,本发明具有行驶灵活性好、结构简单紧凑、易于制作、成本低、工作稳定可靠、转向路径精准等优点。
