The invention relates to a full-degree-of-freedom steering drive-by-wire chassis platform applied to unmanned driving. The platform comprises a suspension system installed between a vehicle frame anda driving system, and the driving system comprises four hub motor belt tire assemblies installed below the suspension system; the four wheels are independently steered through the four steering motorsrespectively, the steering motors conduct speed reduction and torque increase through the speed reducers, the control precision and torque are improved, and steering control over the four wheels is conducted through the chassis controller and the motor controller according to the steering angle of the whole vehicle. The four wheels are connected without a fixed mechanical structure, and the steering angles of the four wheels are adjusted and controlled by the controller, so that the functions of small steering radius, zero steering radius and even transverse driving of the whole vehicle can be realized, the flexibility of the whole vehicle is greatly improved, and the application range is expanded.
一种运用于无人驾驶的全自由度转向的线控底盘平台,包括安装在车架和驱动系统之间的悬架系统,所述驱动系统包括四个安装在悬架系统下的轮毂电机带轮胎总成;通过四个转向电机分别对四个车轮进行独立的转向,转向电机通过减速机进行减速增扭,提高控制精度及扭矩,并通过底盘控制器及电机控制器根据整车的转向角度对四个车轮分别进行转向控制,四个车轮间没有固定的机械结构进行连接,四个车轮转向角度由上述控制器进行调节和控制,因此可以实现整车小转向半径、零转向半径甚至横向行驶功能,极大的提高了整车的灵活性,扩展了使用范围。
