This application relates to an electronically controlled air suspension (ECAS) system. When a vehicle starts, the ECAS system receives data from a wheel height sensor and sets the received height as a default height. When driving, a high-speed line profiler scans the road surface in front of the tires of the vehicle. This information is processed by an image processing unit to determine the amount of air in the corresponding damper. If there is a bump on the road, the ECAS system may reduce the amount of air on the tire side in advance, and if there is a dip, the ECAS system may increase the amount of air on the tire side in advance to minimize vibration. Regarding the residual vibration after passing through the bump or dip, the amount of air is adjusted so that the vibration stops quickly by receiving real-time data from the wheel height sensor.
