The invention discloses a self-adaptive steering control crawler-type chassis system and a control method thereof. The self-adaptive steering control crawler-type chassis system comprises a chassis frame and a controller. Crawler belt assemblies are respectively arranged on two sides of the chassis frame; the crawler belt assembly comprises a driving wheel, a driven wheel, a bearing wheel, a tensioning wheel and a crawler belt; the driving wheel, the driven wheel and the tensioning wheel are all rotationally connected with the chassis frame, and the driving wheel, the driven wheel, the bearing wheel and the tensioning wheel are sleeved with the crawler belt. The bearing wheels are connected with the lifting mechanism, the lifting mechanism is connected with the chassis frame, and the lifting mechanism can drive the bearing wheels to move along the tracks to change the contact area between the tracks and the ground; and the controller is used for controlling the lifting mechanism on the inner side of the turning to drive the bearing wheels to move along the tracks when the vehicle starts to steer, so that the contact area between the tracks on the inner side of the turning and the ground is reduced. During steering, the contact area between the inner side track and the ground during turning is reduced, and the maneuverability, flexibility and response speed of vehicle steering are improved.
本发明公开的一种自适应转向控制的履带式底盘系统及其控制方法,包括底盘框架和控制器;底盘框架的两侧分别设置履带组件;履带组件包括主动轮、从动轮、承载轮、张紧轮和履带;主动轮、从动轮和张紧轮均与底盘框架转动连接,履带套设于主动轮、从动轮、承载轮和张紧轮上;承载轮与提升机构连接,提升机构与底盘框架连接,提升机构能够驱动承载轮沿履带移动,从改变履带与地面的接触面积;控制器,用于当车辆开始转向时,控制转弯内侧的提升机构,来驱动承载轮沿履带移动,减小转弯内侧履带与地面的接触面积。通过转向时,减小转弯内侧履带与地面的接触面积,提升车辆转向的机动性、灵活性和响应速度。
