Comprehensive logging of calibration steps remains critical for meeting warranty requirements and reliable safety system verification.

Dynamic vs Static Calibration Methods

A crucial aspect of ADAS technology is ensuring precise calibration, which is achieved through either static or dynamic methods.

The static calibration process takes place with the vehicle at rest, often in a controlled setting like a workshop. This requires a flat surface, regulated lighting, and professional calibration instruments. This method provides high precision, but it necessitates a specialized facility and is often time-consuming. It's less adaptable and incurs higher facility costs but delivers consistent results, independent of weather.

In contrast, dynamic calibration, or on-road calibration, takes place while the vehicle is in motion. This approach needs clear weather, visible road markings, and particular vehicle velocities. The advantage lies in its flexibility, as it evaluates 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.

Deciding between these methods hinges on vehicle requirements, OEM guidelines, and your workshop's resources. Frequently, both calibrations are necessary to maintain ideal ADAS performance, specifically after services like windscreen changes or wheel alignments.

Each method demands technical knowledge and must be handled carefully to ensure system integrity.

ADAS Camera and Radar Diagnostics

Today's ADAS-equipped vehicles need thorough assessment of sensing systems to guarantee reliable functionality.
