The invention provides a vehicle steering system, a vehicle and a vehicle steering system control method. The vehicle steering system comprises a front axle, a rear axle, a steering angle sensor, a power assisting unit and an electric control unit, the power assisting unit comprises a power assisting piece, and the power assisting piece is connected with the rear axle; the electric control unit comprises a controller and a driving part which are electrically connected, the rotation angle sensor is used for detecting the rotation angle of the front axle and sending a rotation angle signal representing the rotation angle to the controller, and the controller is configured to control the driving part to drive the power assisting part to move according to the rotation angle signal so that the power assisting part can drive the rear axle to rotate. The steering angle of the rear axle tire can be accurately matched, abnormal abrasion of the tire is effectively relieved, and the steering safety of the rear axle is improved.

    本发明提供一种车辆转向系统、车辆及车辆转向系统控制方法。车辆转向系统包括前桥、后桥、转角传感器、助力单元以及电控单元,助力单元包括助力件,助力件与后桥连接;电控单元包括电连接的控制器和驱动件,转角传感器用于检测前桥的转动角度,且向控制器发送表征转动角度的转动角度信号,控制器被配置为根据转动角度信号控制驱动件驱动助力件移动,以使助力件带动后桥转动。本发明使得后桥轮胎转角得以精准匹配,有效减轻轮胎异常磨损,提高后桥转向安全性。
