Abstract
The present invention relates to the technical field of automobile maintenance and discloses a calibration device for a lane keeping assist (LKA) system. The calibration device includes a support apparatus, a laser and a pattern board. The support apparatus includes a horizontal graduated scale. The laser is configured to be mounted on the body of an automobile and to emit a laser beam to the horizontal graduated scale. The pattern board is mounted on the support apparatus and is configured to attach an alignment pattern. By means of the calibration device, two lasers are mounted on wheels on two sides of the automobile. Two laser beams that are emitted from equal distances with the wheels being reference points are irradiated to the horizontal graduated scale. Based on marks on the horizontal graduated scale, the support apparatus may be moved to an appropriate position to calibrate the centerline of the automobile.
