The invention discloses a vehicle electric-control steering road-feel control method based on the drive-by-wire technology. The method comprises the following steps: 1, initializing a system, and continuing with step 2 if no failure is found; 2, centering the steering wheel turning angle and front-wheel turning angle, namely when it is guaranteed that the steering wheel turning angle and the front-wheel turning angle are both at zero point, triggering the road-feel control function, and entering step 3; 3, collecting and identifying the steering system and signals related to the vehicle state and parameters; 4, processing the signals collected in step 3, and obtaining an ideal road-feel feedback target torque value through calculation; 5, conducting closed-loop control on a road-feel simulation motor through the target torque value calculated and obtained in step 4, and achieving the target torque value; 6, adopting a compensation control method for conducting compensation control on the road-feel motor torque value according to the running state of the road-feel simulation motor, and repeating work in step 3 and step 6 till a vehicle shuts down.
