The invention discloses a calibration method of an electric adjustment steering column, and relates to the technical field of automobiles, and the method comprises the following steps: setting a zeroposition of the steering column according to an extreme position of the steering column, and determining a mapping relationship between the number of turns of rotation of a motor and the displacementof the steering column; taking the power-off position of the steering column as a power-off memory position and storing the power-off memory position, and then adjusting the steering column to the zero position of the steering column; the number of rotation turns corresponding to the steering column moving from the zero position to the power-off memory position is used as the theoretical number ofrotation turns of the motor; when the vehicle is powered on again, the steering column is controlled to move according to the theoretical number of turns of rotation, and the powered-on position of the steering column is obtained; and if the error between the power-off memory position and the power-on position is within a preset range, indicating that calibration is completed, otherwise, modifying the mapping relationship between the number of turns of rotation of the motor and the displacement of the steering column according to the error. By means of the calibration method, the steering column can be adjusted more quickly and accurately.

    本申请公开了一种电动调节转向管柱的标定方法,涉及汽车技术领域,该方法包括步骤:根据转向管柱的极限位置,设定转向管柱的零位,并确定电机的旋转圈数与转向管柱位移的映射关系;以转向管柱下电时的位置为下电记忆位置并存储,然后调节转向管柱至转向管柱的零位;以转向管柱自零位移动至下电记忆位置对应的旋转圈数,作为电机的理论旋转圈数;车辆再次上电时,根据理论旋转圈数控制转向管柱移动,得到转向管柱的上电位置;若下电记忆位置与上电位置的误差在预设范围内,则表示标定完成,否则根据误差修改电机的旋转圈数与转向管柱位移的映射关系。本申请的标定方法,可使转向管柱的调节更加快速准确。
