Thorough documentation of calibration steps is essential for meeting warranty requirements and proper safety system verification.

Comparing Static and Dynamic Calibration Methods

An essential element of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which can be accomplished through two main methods.

Static calibration takes place with the vehicle at rest, usually in a specialized workspace like a workshop. The process demands a flat surface, controlled lighting, and professional calibration instruments. This approach provides high precision, but it necessitates a dedicated workspace and can be time-consuming. It's less adaptable and involves greater facility costs but delivers predictable performance, independent of weather.

Alternatively, the dynamic method, or mobile calibration, takes place while the vehicle is in motion. This method demands clear weather, visible road markings, and controlled driving speeds. This method offers its flexibility, as it tests the system in actual driving situations and demands less specific hardware. However, it relies significantly on weather and road conditions, and the outcomes may fluctuate.

Deciding between these methods depends on vehicle requirements, OEM guidelines, and your workshop's resources. Frequently, both calibrations are necessary to maintain ideal ADAS performance, especially after services like windshield replacements or wheel balancing.

Each technique needs specialized skills and should be handled carefully to preserve system integrity.

Diagnostic Procedures for Camera and Radar Systems
