A method for fine-tuning a variable-gear steering column according to a speed of the vehicle, the method includes: a step of characterizing a desired handling of the vehicle for a speed V1 and of characterizing a desired stability for a speed V2; a step of determining a value G1 of the gear ratio allowing obtaining the desired handling at the speed V1, and a value G2 of the gear ratio allowing obtaining the desired stability at the speed V2, a step of calculating a parameter p1 and a parameter p2 according to the speed V1, the speed V2, the value G1 and the value G2 so that the relationship between the gear ratio and the speed of the vehicle is defined by the equation G=p2+p1/V, when the speed is included between a first threshold and a second threshold.
