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.

    本申请涉及一种车辆线控转向的控制方法、控制系统以及计算机可读介质。其中,所述车辆线控转向的控制方法包括:获取方向盘的操作力矩;根据该操作力矩与传动比得到向转向器输出的目标力矩的值;输出该目标力矩;其中,对应车辆速度在第一速度以下,所述目标力矩为所述操作力矩与第一传动比A1的乘积;对应车辆速度在第一速度与第二速度之间,所述目标力矩为所述操作力矩与第二传动比A2的乘积;对应车辆速度在第二速度以上,所述目标力矩为所述操作力矩与第三传动比A3的乘积;其中,所述第一传动比A1、第二传动比A2、第三传动比A3的之间的关系为行星齿轮机构的传动比:A1=1+α;A2=α;A3=1+1/α;其中,α大于1。
