Detailed recording of calibration steps is essential for warranty compliance and effective safety system verification.

Dynamic vs Static Calibration Methods

An essential element of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which is achieved through either static or dynamic methods.

Static calibration procedures is conducted with the vehicle stationary, usually in a specialized workspace like a workshop. The process demands a flat surface, regulated lighting, and professional calibration instruments. This method provides high precision, but it demands a dedicated workspace and is often time-consuming. It's less adaptable and requires substantial facility costs but ensures consistent results, not influenced by weather.

On the other hand, dynamic calibration, or mobile calibration, is performed while the vehicle is being driven. This approach requires 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 requires less dedicated tools. However, it is greatly influenced by weather and road conditions, and the results can vary.

Selecting from these methods depends on vehicle requirements, OEM guidelines, and your workshop's resources. In many cases, both calibrations are essential to guarantee ideal ADAS performance, specifically after services like windscreen changes or alignment services.

Each approach demands technical knowledge and should be approached with precision to ensure system integrity.

Camera and Radar System Diagnostics
