Static vs Dynamic Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which can be accomplished through two main methods.

Static calibration procedures takes place with the vehicle stationary, often in a controlled environment like a workshop. The process demands a level surface, proper illumination, and professional calibration instruments. This approach offers high precision, but it requires a dedicated workspace and tends to be time-consuming. It's more rigid and requires substantial facility costs but guarantees reliable outcomes, independent of weather.

On the other hand, dynamic calibration procedures, or on-road calibration, occurs while the vehicle is in motion. This approach demands clear weather, well-defined lane markers, and particular vehicle velocities. This method offers its flexibility, as it assesses the system in practical scenarios and needs less specialized equipment. However, it depends heavily on weather and road conditions, and the outcomes may fluctuate.

Deciding between these methods is based on specific vehicle needs, OEM guidelines, and your service center's capacity. In many cases, both calibrations are required to ensure ideal ADAS performance, specifically after services like windshield replacements or alignment services.

Each method demands technical knowledge and should be executed precisely to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems
