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

Comparing Static and Dynamic Calibration Methods

An essential element of ADAS technology is guaranteeing precise calibration, which is achieved through both static and dynamic methods.

Static calibration is performed with the vehicle stationary, often in a specialized workspace like a workshop. The process demands a flat surface, regulated lighting, and professional calibration instruments. This method delivers high precision, but it necessitates a specialized facility and tends to be time-consuming. It's less flexible and incurs higher facility costs but guarantees predictable performance, not influenced by weather.

Alternatively, dynamic calibration, or mobile calibration, is performed while the vehicle is moving. This process demands clear weather, visible road markings, and controlled driving speeds. The advantage lies in its flexibility, as it tests the system in actual driving situations and needs less specific hardware. However, it is greatly influenced by weather and road conditions, and the results can vary.

Deciding between these methods is based on specific vehicle needs, OEM guidelines, and your service center's capacity. Frequently, both calibrations are required to guarantee ideal ADAS performance, particularly after services like windshield replacements or wheel balancing.

Each technique demands professional expertise and must be executed precisely to preserve system integrity.

ADAS Camera and Radar Diagnostics
