Comprehensive logging of these procedures is essential for meeting warranty requirements and effective safety system verification.

Static vs Dynamic Calibration Methods

A crucial aspect of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which is performed through two main methods.

Static calibration procedures takes place with the vehicle at rest, typically in a controlled environment like a workshop. This requires a level surface, controlled lighting, and professional calibration instruments. This approach offers high precision, but it requires a specialized facility and tends to be time-consuming. It's more rigid and incurs higher facility costs but delivers consistent results, unaffected by weather.

On the other hand, dynamic calibration procedures, also known as mobile calibration, is performed while the vehicle is in motion. This approach needs clear weather, visible road markings, and controlled driving speeds. You'll benefit from its flexibility, as it tests the system in real-world conditions and demands less specific hardware. However, it is greatly influenced by weather and road conditions, and the outcomes may fluctuate.

Deciding between these methods is based on specific vehicle needs, manufacturer requirements, and your service center's capacity. Often, both calibrations are essential to maintain ideal ADAS performance, specifically after services like glass installations or wheel balancing.
