[0003] For commercial vehicles equipped with air suspension, the ECAS controller needs to be calibrated for airbag height adjustment parameters. The calibration process requires multiple (3-10 times) inflation and deflation measurements to check the height of the airbag from the ground.

The process is cumbersome, resulting in high intensity, low efficiency, and poor consistency in ECAS calibration work, which seriously affects employee enthusiasm. The existing distance measuring device measures the process of air suspension calibration adjustment with repeated manual measurements and hidden dangers such as deflection and inaccurate distance measurement. The measurement accuracy is low, and it is inconvenient to carry, operate, and use. Utility Model Content
