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

Dynamic vs Static Calibration Methods

An essential element of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which is performed through two main methods.

The static calibration process is conducted with the vehicle immobile, often in a controlled setting like a workshop. The process demands a level surface, controlled lighting, and professional calibration instruments. This approach offers high precision, but it requires a specialized facility and tends to be time-consuming. It's less flexible and incurs higher facility costs but guarantees reliable outcomes, not influenced by weather.

In contrast, dynamic calibration procedures, or mobile calibration, occurs while the vehicle is in motion. This process demands clear weather, well-defined lane markers, and controlled driving speeds. This method offers its flexibility, as it assesses the system in practical scenarios and requires less specialized equipment. However, it relies significantly on weather and road conditions, and the results can vary.

Selecting from these methods hinges on vehicle requirements, manufacturer requirements, and your facility's capabilities. In many cases, both calibrations are necessary to ensure ideal ADAS performance, especially after services like windshield replacements or alignment services.
