The invention discloses a vehicle steer-by-wire system. The steer-by-wire system comprises a steering wheel, a first steering shaft, a torque sensor, a first motor, a first differential mechanism, a first angle sensor, a first controller, a first clutch, a second steering shaft, a universal joint, a second motor, a second differential mechanism, a second angle sensor, a gear and rack mechanism, anaxle and a second controller. The steer-by-wire system not only can be applied to traditional vehicle steering, but also can be applied to a steering system of an automatic driving technology, on onehand, automatic switching between traditional steering and automatic driving steering is achieved, and on the other hand, function backup of the automatic driving steering system can be achieved.

    本发明公开了一种车用线控转向系统,其包括:方向盘、第一转向轴、力矩传感器、第一电机、第一差速器、第一角传感器、第一控制器,第一离合器、第二转向轴、万向节、第二电机、第二差速器、第二角传感器、齿轮齿条机构、车轴与第二控制器。该套转向系统既可以应用在传统的车辆转向上,也可以应用在自动驾驶技术的转向系统上,一方面实现传统转向与自动驾驶转向的自动切换,同时还可以实现自动驾驶转向系统的功能备份。
