The invention relates to a vehicle steer-by-wire control method, a vehicle steer-by-wire control system and a computer readable medium. The vehicle steer-by-wire control method comprises the steps that the operation torque of a steering wheel is obtained; obtaining a value of a target torque output to the steering gear according to the operation torque and the transmission ratio; outputting the target torque; wherein the corresponding vehicle speed is below the first speed, and the target torque is the product of the operation torque and the first transmission ratio A1; the corresponding vehicle speed is between the first speed and the second speed, and the target torque is the product of the operation torque and a second transmission ratio A2; when the corresponding vehicle speed is higher than the second speed, the target torque is the product of the operation torque and a third transmission ratio A3; wherein the relation among the first transmission ratio A1, the second transmission ratio A2 and the third transmission ratio A3 is the transmission ratio of the planetary gear mechanism: A1 = 1 + alpha; a2 = alpha; a3 = 1 + 1/alpha; wherein alpha is greater than 1.
