Comprehensive logging of these procedures is essential for warranty compliance and reliable safety system verification.

Static vs Dynamic Calibration Methods

A key component of ADAS technology is maintaining precise calibration, which is achieved through either static or dynamic methods.

The static calibration process is conducted with the vehicle stationary, often in a controlled environment like a workshop. The process demands a flat surface, regulated lighting, and specialized calibration tools. This method delivers high precision, but it demands a dedicated workspace and is often time-consuming. It's more rigid and incurs higher facility costs but guarantees predictable performance, not influenced by weather.

In contrast, dynamic calibration procedures, also known as mobile calibration, takes place while the vehicle is moving. This method demands clear weather, well-defined lane markers, and specific driving speeds. The advantage lies in its flexibility, as it tests the system in real-world conditions and demands less specific hardware. However, it depends heavily on weather and road conditions, and the performance can differ.

Deciding between these methods is based on specific vehicle needs, manufacturer specifications, and your facility's capabilities. In many cases, both calibrations are required to guarantee ideal ADAS performance, specifically after services like windscreen changes or alignment services.

Each approach demands professional expertise and needs to be executed precisely to ensure system integrity.

ADAS Camera and Radar Diagnostics
