A vehicle steering system includes a front wheel steering device, a rear wheel steering device, a steering domain controller, and a vehicle controller for outputting a zero-radius steering command or a four-wheel steering command to the steering domain controller, and when the zero-radius steering command is output, the four-wheel steering command is output to the steering domain controller, and when the four-wheel steering command is output, the four-wheel steering command is output to the steering domain controller. When a four-wheel steering instruction is output, the steering domain controller can control the two front wheel rotation transmission assemblies and the two rear wheel rotation transmission assemblies to output rotation movement in different steering directions, and when a four-wheel steering instruction is output, the steering domain controller can control the two front wheel rotation transmission assemblies to output rotation movement in the same steering direction. And the two rear wheel rotating transmission assemblies are controlled to output rotating motion in the same rotating direction. According to the vehicle steering system, multi-mode and multi-functional steering functions such as a zero-radius steering mode or a four-wheel steering mode can be realized, so that the driving safety of the vehicle is improved.

    一种车辆转向系统和转向方法,转向系统包括:前轮转向装置,后轮转向装置,转向域控制器以及车辆控制器,车辆控制器用于向转向域控制器输出零半径转向指令或四轮转向指令,当输出零半径转向指令时,转向域控制器可控制两个前轮转动传动组件和两个后轮转动传动组件均输出不同转向的旋转运动,当输出四轮转向指令时,转向域控制器可控制两个前轮转动传动组件均输出相同转向的旋转运动,控制两个后轮转动传动组件均输出相同转向的旋转运动。本车辆转向系统能够实现零半径转向模式或者四轮转向模式等多模式、多功能的转向功能,以提高车辆行驶安全性。
