The invention provides a road feeling simulator for steer-by-wire and a control system and method of the road feeling simulator. The road feeling simulator comprises a magnetorheological fluid damper and a steering column. The steering column comprises a steering column shell, a steering shaft is installed in the steering column shell, and one end of the steering shaft extends out of the steering column shell. In the steering column shell, the steering shaft at least comprises a section of lead screw structure, a lead screw nut is installed on the circumference of the outer side of the lead screw structure, a sliding groove is formed in the circumference of the outer side of the lead screw nut, and a limiting block is embedded in the sliding groove. A first spring seat and a second spring seat are installed on the two sides of the lead screw nut respectively, and the steering shaft is configured to rotate relative to the first spring seat and the second spring seat. A first spring is installed between the first spring seat and the lead screw nut, a second spring is installed between the second spring seat and the lead screw nut, and the first spring and the second spring are in a compressed state. The operation hand feeling of the road feeling simulator is improved, and noise generated by the road feeling simulator is reduced.

    本发明提供了一种用于线控转向的路感模拟器及其控制系统、方法,所述路感模拟器包括磁流变液阻尼器和转向柱;转向柱包括转向柱壳体,在转向柱壳体内安装转向轴,转向轴一端伸出转向柱壳体;在转向柱壳体内,转向轴至少包括一段丝杠结构,在丝杠结构外侧圆周安装丝杠螺母,丝杠螺母外侧圆周开设滑槽,滑槽内嵌入一限位块;在丝杠螺母两侧分别安装第一弹簧座和第二弹簧座,并且转向轴被配置为:相对第一弹簧座和第二弹簧座转动;第一弹簧座与丝杠螺母之间安装第一弹簧,第二弹簧座与丝杠螺母之间安装第二弹簧,并且第一弹簧和第二弹簧处于压缩状态。本发明提升了路感模拟器的操作手感,降低了路感模拟器产生的噪声。
