Detailed recording of these procedures remains critical for meeting warranty requirements and reliable verification of safety systems.

Dynamic vs Static Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which can be accomplished through both static and dynamic methods.

Static calibration is conducted with the vehicle immobile, often in a specialized workspace like a workshop. You'll need a level surface, controlled lighting, and specialized calibration tools. This approach offers high precision, but it demands a designated area and tends to be time-consuming. It's less adaptable and requires substantial facility costs but ensures predictable performance, independent of weather.

On the other hand, dynamic calibration, or mobile calibration, occurs while the vehicle is moving. This process requires clear weather, visible road markings, and particular vehicle velocities. You'll benefit from its flexibility, as it evaluates the system in real-world conditions and demands less specialized equipment. However, it depends heavily on weather and road conditions, and the results can vary.

Choosing between these methods depends on automotive specifications, OEM guidelines, and your service center's capacity. Often, both calibrations are required to guarantee ideal ADAS performance, especially after services like windscreen changes or alignment services.

Each approach demands technical knowledge and needs to be approached with precision to preserve system integrity.

Diagnostic Procedures for Camera and Radar Systems
