Thorough documentation of these processes is essential for warranty compliance and reliable verification of safety systems.

Comparing Static and Dynamic Calibration Methods

A crucial aspect of Advanced Driver Assistance Systems (ADAS) is maintaining precise calibration, which is performed through two main methods.

The static calibration process takes place with the vehicle at rest, usually in a specialized workspace like a workshop. The process demands a level floor, controlled lighting, and professional calibration instruments. This technique offers high precision, but it demands a specialized facility and tends to be time-consuming. It's less adaptable and incurs higher facility costs but delivers reliable outcomes, independent of weather.

On the other hand, dynamic calibration, also known as mobile calibration, takes place while the vehicle is in motion. This method requires clear weather, visible road markings, and specific driving speeds. This method offers its flexibility, as it tests the system in actual driving situations and demands less dedicated tools. However, it relies significantly on weather and road conditions, and the performance can differ.

Selecting from these methods hinges on automotive specifications, manufacturer requirements, and your facility's capabilities. Often, both calibrations are required to ensure ideal ADAS performance, particularly after services like windscreen changes or wheel alignments.
