The invention relates to a steer-by-wire system and an automobile. The steer-by-wire system comprises a steering gear, a hydraulic cylinder unit, a damper unit and a steering wheel. The hydraulic cylinder unit is provided with a first hydraulic cavity and a second hydraulic cavity; when the steering wheel rotates clockwise, the steering gear can apply force to the hydraulic cylinder unit so as to compress the first hydraulic cavity; when the steering wheel rotates anticlockwise, the steering gear can apply force to the hydraulic cylinder unit so as to compress the second hydraulic cavity; the damper unit is provided with a first cavity, a second cavity and a torsion bar, the first cavity is communicated with the first hydraulic cavity, the second cavity is communicated with the second hydraulic cavity, and the torsion bar is connected with the steering wheel; when fluid is introduced into the first chamber body, the torsion bar can be driven to rotate anticlockwise; and when fluid is introduced into the second chamber body, the torsion bar can be driven to rotate clockwise. During steering, the steering gear can directly apply force to the hydraulic system, and the feedback force is transmitted to the steering wheel through the hydraulic system, so that the steering hand feeling is more real and reliable and meets the expectation, and a driver is prevented from feeling unsafe.

    本发明涉及一种线控转向系统及汽车,包括转向器、液压缸单元、阻尼器单元及方向盘;液压缸单元具有第一液压腔和第二液压腔;方向盘顺时针转动时,转向器能够对液压缸单元施力,以压缩第一液压腔;方向盘逆时针转动时,转向器能够对液压缸单元施力,以压缩第二液压腔;阻尼器单元具有第一腔室、第二腔室及扭杆,第一腔室与第一液压腔连通,第二腔室与第二液压腔连通,扭杆与方向盘连接;第一腔室体内通入流体时,能够驱动扭杆逆时针转动;第二腔室体内通入流体时,能够驱动扭杆顺时针转动。转向时,转向器可以直接对该液压系统施力,并通过该液压系统将反馈力传递至方向盘,从而使转向手感更加真实可靠并满足预期,从而避免驾驶员出现不安全感。
