Detailed recording of calibration steps remains critical for meeting warranty requirements and effective safety system verification.

Dynamic vs Static Calibration Methods

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

The static calibration process is conducted with the vehicle immobile, often in a controlled environment like a workshop. You'll need a level surface, regulated lighting, and specific calibration equipment. This approach delivers high precision, but it necessitates a designated area and tends to be time-consuming. It's less flexible and requires substantial facility costs but ensures reliable outcomes, unaffected by weather.

In contrast, dynamic calibration procedures, also known as mobile calibration, occurs while the vehicle is in motion. This approach needs clear weather, well-defined lane markers, and particular vehicle velocities. This method offers its flexibility, as it assesses the system in actual driving situations and demands less specific hardware. However, it relies significantly on weather and road conditions, and the performance can differ.

Choosing between these methods hinges on automotive specifications, OEM guidelines, and your service center's capacity. Frequently, both calibrations are necessary to ensure ideal ADAS performance, specifically after services like windscreen changes or alignment services.

Each method demands specialized skills and should be executed precisely to maintain system integrity.

ADAS Camera and Radar Diagnostics

Modern ADAS vehicles require a meticulous approach to diagnosing camera and radar systems to ensure optimal performance.
