METHOD FOR ALIGNING CALIBRATION DEVICE WITH VEHICLE AND AUXILIARY TARGET

The present invention relates to the field of the vehicle maintenance and repair as well as device calibration and provides a method and auxiliary target for aligning a calibration device to a vehicle. The calibration device includes a calibration bracket and a calibration laser emitter. The calibration bracket includes a crossbar. The method includes: placing a vehicle on a horizontal plane; setting a calibration center point, so that the calibration center point is located on a line of intersection of a central axial plane of the vehicle and the horizontal plane and the calibration center point is at a preset calibration distance from a plane extending through a head of the vehicle and perpendicular to the horizontal plane, or the calibration center point is at the preset calibration distance from a plane extending through centers of two front wheels of the vehicle and perpendicular to the horizontal plane; turning on the calibration laser emitter, so that the calibration laser emitter emits two sector-shaped rays of light, the two sector-shaped rays of light forming, on the horizontal plane, a first laser line and a second laser line that intersect and are perpendicular to each other; and adjusting a position of the crossbar, so that a point of intersection of the first laser line and the second laser line coincides with the calibration center point and the first laser line coincides with the line of intersection of the central axial plane of the vehicle and the horizontal plane. By means of the method for aligning a calibration device to a vehicle, alignment of the calibration device to the vehicle can be achieved easily and quickly.
