Thorough documentation of these procedures is essential for meeting warranty requirements and reliable verification of safety systems.

Dynamic vs Static Calibration Methods

An essential element of Advanced Driver Assistance Systems (ADAS) is maintaining precise calibration, which is achieved through both static and dynamic methods.

The static calibration process takes place with the vehicle immobile, often in a controlled environment like a workshop. The process demands a flat surface, proper illumination, and specialized calibration tools. This approach delivers high precision, but it requires a specialized facility and tends to be time-consuming. It's less flexible and involves greater facility costs but guarantees reliable outcomes, unaffected by weather.

On the other hand, dynamic calibration, also known as mobile calibration, occurs while the vehicle is being driven. This approach needs clear weather, well-defined lane markers, and controlled driving speeds. The advantage lies in its flexibility, as it evaluates the system in real-world conditions and needs less specialized equipment. However, it relies significantly on weather and road conditions, and the outcomes may fluctuate.

Deciding between these methods hinges on automotive specifications, OEM guidelines, and your workshop's resources. Often, both calibrations are necessary to maintain ideal ADAS performance, particularly after services like glass installations or alignment services.
