Detailed recording of these processes is essential for meeting warranty requirements and reliable verification of safety systems.

Dynamic vs Static Calibration Methods

An essential element of Advanced Driver Assistance Systems (ADAS) is maintaining precise calibration, which is achieved through either static or dynamic methods.

The static calibration process takes place with the vehicle immobile, usually in a specialized workspace like a workshop. This requires a level floor, controlled lighting, and professional calibration instruments. This approach delivers high precision, but it demands a dedicated workspace and can be time-consuming. It's less flexible and involves greater facility costs but delivers consistent results, independent of weather.

In contrast, dynamic calibration, or on-road calibration, occurs while the vehicle is being driven. This approach demands clear weather, visible road markings, and controlled driving speeds. The advantage lies in its flexibility, as it evaluates the system in real-world conditions and needs less specific hardware. However, it relies significantly on weather and road conditions, and the outcomes may fluctuate.

Deciding between these methods depends on automotive specifications, manufacturer requirements, and your facility's capabilities. Frequently, both calibrations are essential to guarantee ideal ADAS performance, especially after services like glass installations or alignment services.

Each approach needs technical knowledge and should be approached with precision to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems
