A method (100) for trimming a variable gear steering column (G) according to a speed (v) of a vehicle, the method (100) comprising: a step (101) of characterizing a desired maneuverability of the vehicle for a speed V1 and a desired stability for a speed V2; step (102): determining a value G1 of a gear ratio allowing a desired maneuverability to be obtained at a speed V1 and a value G2 of a gear ratio allowing a desired stability to be obtained at a speed V2, Step (103): calculating a parameter p1 and a parameter p2 as a function of the speed V1, the speed V2, the value G1 and the value G2 such that when the speed (V) is comprised between a first threshold value and a second threshold value, the parameter p1 is greater than the parameter p2, and if the speed (V) is less than the first threshold value, the parameter p2 is greater than the first threshold value. The relationship between the gear ratio (G) and the speed (V) of the vehicle is defined by the equation G = p2 + p1/V. 一种用于根据车辆的速度(v)微调可变齿轮转向柱(G)的方法(10
