Detailed recording of these procedures remains critical for warranty compliance and effective verification of safety systems.

Dynamic vs Static Calibration Methods

A crucial aspect of Advanced Driver Assistance Systems (ADAS) is maintaining precise calibration, which can be accomplished through either static or dynamic methods.

The static calibration process takes place with the vehicle at rest, usually in a controlled environment like a workshop. This requires a flat surface, regulated lighting, and specific calibration equipment. This method delivers high precision, but it requires a specialized facility and is often time-consuming. It's more rigid and incurs higher facility costs but delivers consistent results, unaffected by weather.

On the other hand, dynamic calibration, also known as mobile calibration, occurs while the vehicle is moving. This process demands clear weather, clear road lines, and controlled driving speeds. The advantage lies in its flexibility, as it assesses the system in actual driving situations and demands less dedicated tools. However, it depends heavily on weather and road conditions, and the outcomes may fluctuate.

Selecting from these methods hinges on vehicle requirements, manufacturer specifications, and your facility's capabilities. Often, both calibrations are required to maintain ideal ADAS performance, specifically after services like windshield replacements or wheel balancing.

Each approach requires technical knowledge and must be executed precisely to preserve system integrity.

Diagnostic Procedures for Camera and Radar Systems
