Thorough documentation of calibration steps is essential for warranty compliance and proper verification of safety systems.

Static vs Dynamic Calibration Methods

A key component of driver assistance systems is maintaining precise calibration, which is performed through two main methods.

The static calibration process is performed with the vehicle at rest, typically in a controlled setting like a workshop. You'll need a flat surface, proper illumination, and specific calibration equipment. This technique offers high precision, but it demands a designated area and tends to be time-consuming. It's more rigid and involves greater facility costs but delivers consistent results, independent of weather.

In contrast, dynamic calibration procedures, also known as mobile calibration, takes place while the vehicle is in motion. This approach demands clear weather, clear road lines, and particular vehicle velocities. The advantage lies in its flexibility, as it evaluates the system in actual driving situations and demands less dedicated tools. However, it relies significantly on weather and road conditions, and the results can vary.

Selecting from these methods is based on automotive specifications, manufacturer requirements, and your workshop's resources. Often, both calibrations are required to maintain ideal ADAS performance, especially after services like glass installations or wheel alignments.

Each method demands specialized skills and must be approached with precision to preserve system integrity.

Diagnostic Procedures for Camera and Radar Systems
