Thorough documentation of these processes is crucial for meeting warranty requirements and effective verification of safety systems.

Comparing Static and Dynamic Calibration Methods

A key component of ADAS technology is maintaining precise calibration, which is performed through both static and dynamic methods.

Static calibration is performed with the vehicle stationary, often in a specialized workspace like a workshop. This requires a flat surface, regulated lighting, and professional calibration instruments. This technique offers high precision, but it necessitates a designated area and tends to be time-consuming. It's more rigid and incurs higher facility costs but ensures predictable performance, not influenced by weather.

On the other hand, dynamic calibration, also known as mobile calibration, takes place while the vehicle is moving. This process requires clear weather, well-defined lane markers, and particular vehicle velocities. The advantage lies in its flexibility, as it tests the system in real-world conditions and needs less specific hardware. However, it relies significantly on weather and road conditions, and the results can vary.

Deciding between these methods hinges on vehicle requirements, manufacturer requirements, and your facility's capabilities. In many cases, both calibrations are required to maintain ideal ADAS performance, especially after services like windscreen changes or wheel alignments.

Each method needs professional expertise and must be approached with precision to maintain system integrity.

Camera and Radar System Diagnostics
