Description

Technical Field

[0001] The present invention relates to the technical field of brackets, in particular to a universal ADB system calibration bracket. Background Art

[0002] At present, most traditional LED lighting systems only require hard-wired controllers to work, while the ADB lighting system requires CAN communication controllers, camera sensors, and VLS sensors in addition to LED lights. The ADB ECU collects information through cameras and VLS sensors, and the ADB lights execute a variety of LED light matrixes. Therefore, software calibration of the ADB system is required during the research and development stage. At present, developmental software calibration is generally performed on actual vehicles. Since the ADB system is generally an early research and development project, there are almost no matching vehicles for software calibration, and only non-matching vehicles can be used for calibration.

[0003] Currently, ADB system calibration requires high-precision vehicle testing, which is generally done in the pre-research and development stage. There is no vehicle matching test in the ADB development stage, and only basic functions can be implemented, but accurate calibration cannot be completed. Summary of the invention
