The invention relates to a steer-by-wire system of a vehicle and a control method of the steer-by-wire system. The system comprises a supporting beam, the supporting beam comprises two supporting ends, a steering knuckle is arranged at each supporting end, and each steering knuckle can rotate around the corresponding supporting end of the supporting beam; the driving mechanisms are arranged in one-to-one correspondence with the steering knuckles, each driving mechanism comprises an electric driving device and a transmission device, and the transmission devices are connected to the electric driving devices and engaged with the steering knuckles so as to transmit power provided by the electric driving devices to the steering knuckles when the electric driving devices are started, so that the steering knuckles can rotate; and the connecting rod comprises two connecting end parts, and each connecting end part is connected with one steering knuckle lever, so that the two steering knuckles move synchronously. According to the invention, pure electric wheel edge steering is realized on the basis of high bearing capacity; the types of key parts are reduced, and the manufacturing cost is reduced; when one-side steering fails, the vehicle can run normally.
本发明是关于一种车辆的线控转向系统及其控制方法。该系统包括:支撑梁,支撑梁包括两个支撑端部,在每个支撑端部处分别设置有一个转向节,每个转向节能够绕着支撑梁的相应的支撑端部转动;与每个转向节一一对应地设置的驱动机构,驱动机构包括电力驱动装置和传动装置,传动装置连接至电力驱动装置并且与转向节相接合,从而在电力驱动装置被启用时将由电力驱动装置提供的动力传输至转向节,以使转向节能够转动;连接杆,连接杆包括两个连接端部,每个连接端部分别与一个转向节杠杆连接,从而使两个转向节的运动同步。本发明在高承载的基础上实现纯电动轮边转向;减少关键零部件种类,降低制造成本;在单侧转向失效时,使车辆能够正常行驶。
