Comprehensive logging of these procedures is essential for meeting warranty requirements and reliable verification of safety systems.

Comparing Static and Dynamic Calibration Methods

A crucial aspect of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which is achieved through either static or dynamic methods.

The static calibration process takes place with the vehicle immobile, typically in a controlled setting like a workshop. This requires a flat surface, proper illumination, and specialized calibration tools. This approach offers high precision, but it requires a specialized facility and tends to be time-consuming. It's less flexible and involves greater facility costs but delivers predictable performance, independent of weather.

On the other hand, dynamic calibration, also known as mobile calibration, is performed while the vehicle is being driven. This process requires clear weather, well-defined lane markers, and controlled driving speeds. This method offers its flexibility, as it evaluates the system in practical scenarios and demands less specialized equipment. However, it relies significantly on weather and road conditions, and the performance can differ.

Deciding between these methods depends on vehicle requirements, manufacturer requirements, and your workshop's resources. Often, both calibrations are required to guarantee ideal ADAS performance, specifically after services like glass installations or wheel alignments.

Each technique needs professional expertise and should be handled carefully to ensure system integrity.

Camera and Radar System Diagnostics
