The invention discloses a middle-position calibrating method for an electric power-assisted steering tube column. The middle-position calibrating method comprises the following steps: S1, detecting whether the whole vehicle state, including tire pressure values of tires, and toe-in values of front wheels, meet requirements or not before starting an engine, and besides, detecting whether a handwheel, a steering mechanism and a steering wheel are positioned at the middle position of the whole vehicle; S2, if middle-position calibration is not performed on the electric power-assisted steering tube column, or the middle-position calibration for the electric power-assisted steering tube column is not finished, executing S3, wherein an indication module continuously flashes for indication; S3, comparing standard middle-position information with middle-position calibration information of the electric power-assisted steering tube column, which is detected in real time, if the middle-position calibration information of the electric power-assisted steering tube column, which is detected in real time, is not matched with the standard middle-position information, performing middle-position calibration correcting operation; and S4, if the electric power-assisted steering tube column does not need to continue middle-position calibration, indicating that the middle-position calibration of the electric power-assisted steering tube column is correct by the indication module. The middle-position calibrating method disclosed by the invention is convenient and easy to operate.
