The invention discloses a road feeling feedback method and device based on steer-by-wire. The method comprises the steps that vehicle signal data including execution motor current are collected; wherein the execution motor current reflects rack force on a rack connected with a wheel, and road excitation passes through the wheel and is transmitted to the execution motor through the rack force, so that the execution motor current is formed; obtaining road feeling intensity and road feeling frequency according to the vehicle signal data; generating a road sensing moment according to the road sensing intensity and the road sensing frequency; wherein the road sensing moment reflects contact information of a tire and a road surface and vehicle motion state information; and the road sensing torque is fed back to a steering wheel. According to the invention, the authenticity of sensing the characteristics of the road surface experienced by the current wheel through the steering wheel is improved, and the driving safety is improved.
