Detailed recording of these processes remains critical for warranty compliance and reliable verification of safety systems.

Static vs Dynamic Calibration Methods

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

Static calibration procedures is performed with the vehicle at rest, usually in a specialized workspace like a workshop. You'll need a flat surface, proper illumination, and specific calibration equipment. This method offers high precision, but it necessitates a designated area and tends to be time-consuming. It's more rigid and involves greater facility costs but delivers predictable performance, independent of weather.

In contrast, dynamic calibration, also known as mobile calibration, is performed while the vehicle is in motion. This approach requires clear weather, clear road lines, and particular vehicle velocities. This method offers its flexibility, as it evaluates the system in actual driving situations and demands less specialized equipment. However, it depends heavily on weather and road conditions, and the performance can differ.

Choosing between these methods depends on specific vehicle needs, manufacturer specifications, and your facility's capabilities. Frequently, both calibrations are essential to maintain ideal ADAS performance, specifically after services like windscreen changes or wheel balancing.

Each approach demands professional expertise and should be approached with precision to maintain system integrity.

Camera and Radar System Diagnostics
