The invention discloses an automobile steer-by-wire road feel simulation device and a control method thereof, and relates to the technical field of automobile steering experiments, the road feel simulation device comprises a mechanical transmission mechanism and an information acquisition and control mechanism, and the road feel simulation device comprises a road feel simulation mechanism and a steering wheel aligning mechanism. The road feel feedback device which is accurate in control and rapid in response is provided for a vehicle steer-by-wire system, the adopted magneto-rheological dampercan provide road feel feedback torque in real time according to different road conditions and working conditions under excitation of different exciting currents, and road feel feedback information isprovided for a driver; when the road feel feedback moment is given to the steer-by-wire system, the connection with the magneto-rheological damper can be accurately disconnected during automatic aligning, and the influence of friction and viscous resistance moment of the magneto-rheological damper on automatic aligning is avoided; the safety problem caused by the fact that the feedback motor drives the steering wheel to rotate disorderly when the control system breaks down is avoided, and safety of drivers and passengers is guaranteed.
